Among the electrical machines the shaded pole motors are the most difficult ones in terms of modeling and analysis. This difficulty is arising from the non-uniform airgap and unbalanced windings on its stator. Because ofthese the airgap flux contains rich space harmonics, and this complicates the mathematical modeling and simulation of these machines. On the other hand, small size of these machines results in strong end effects. Hence the 3-D modeling of magnetic field analysis poses an important advantage. Therefore, in this presentation a 15 W, 4 pole shaded pole motor has been modelled in 3-D using Finite Elements (FE) method to determine some important performance parameters such as the airgap flux distribution and the saturation effects in the motor laminations. In this process magnetic field distribution have been obtained for three different case which are: a) Main winding is excited but shading rings and rotor cage are not excited b) Shading rings are excited, but stator winding and rotor cage are not excited c) Both the stator winding and shading rings are excited, but rotor cage is not excited Finally, advantages accrued from such an analysis is discussedin detail.

Thyroid cancer is the type of cancer caused by the cells of the thyroid gland. This is less common than other types of cancer. If the correct diagnosis is made and appropriate treatment is given, the disease can be completely removed. In this study, 3D models of thyroid cancer were modeled using DICOM images. As is known, dicom is the de-facto file standard in medical imaging, and these files contain many metadata. We used some of these meta-attributes to calculate the Hounsfield Unit. In addition, the pixel values are calculated according to the average attenuation of the tissue corresponding to a scale of -1024 to + 3071 on the Hounsfield scale. The DICOM images used in the study were obtained from real patients under the supervision of specialist doctors. Thyroid cancer tumors were modeled as 3D using the pixel values of Marching Cubes Algorithm.

In any working environment, to perform visual tasks efficiently and accurately, adequate and appropriate lighting should be provided. The quantity and quality of illumination in any work place control by the type and duration of activity. The Illumination can be provided by daylight and artificial light together or separately. To calculate the illumination intensity at point C on the R plane from a light source at point A where the light distribution in space is known; besides the direct rays from point A to point C, the rays reflected from other planes must also be considered. By using this information, for inner work area a computer-aided modeling application has been developed by developing an algorithm that recommends the number and location of the selected luminaire considering the minimum illumination level recommendation specified in EN 12464-1 standard (which is European Standard that specifies lighting requirements for indoor work places). In this study, it was aimed to provide visual comfort in closed areas by focusing on only artificial light illumination.

The number of people with some kind of physical disabilities in the world is around 1 billion. The rate of people who need physiotherapy increases with the aging world population every passing day. Physiotherapy may not be completed with exercises made only in hospital. Therefore, patients should do the exercises given by the physiotherapist at home. The main problem here is that only 31% of the exercises performed by the patients are done correctly. Nowadays, in addition to traditional treatment methods there are studies on telerehabilitation to solve such problems. The aim of this study is to ensure that the shoulder rehabilitation exercises are performed at home by the patients and to provide physiotherapists with meaningful data about the exercises. In this study, Improved Shoulder Physiotherapy Application (ISPA) was presented using Microsoft Kinect 2 for shoulder rehabilitation exercises. ISPA is a hardware and software product that uses the joints on the patient's skeletal system. In the proposed system, the angular values are calculated using the joint points taken from Kinect 2 and the patients are simultaneously guided to do shoulder rehabilitation exercises correctly.

Forest fire is an important issue that damages thousands of hectares of forest and all creatures inside it. In this study we have developed an early fire detection system running on low-cost, lightweight Raspberry Pi module integrated with an infrared camera. The infrared camera acquires the live video of the fields, then if a fire occurs, our software detects the fire by taking both motion and color characteristics of a flames into account. In our study, there exist two phases: first, motion detection phase is applied to the view, if a motion is detected in the view, then, color detection phase is applied to determine the flames. Obtained results indicates that our fire detection system can detect a forest fire clearly and smoothly without requiring any external equipment and manual intervention.

It has been widely assumed by the research community that the network reconnaissance attacks in IPv6 networks are unfeasible because they would take tremendous effort to perform address scanning of 2^64 hosts in an IPv6 subnet. However, recent research has revealed feasibility of these attacks by investigating a number of native IPv6 networks. The research concluded that an intelligent attacker could easily reduce the target search space by predicting the network host addressing schemes when performing the scanning. This indeed enhances security concerns and undermines the chances of IPv6 being deployed. This paper overviews the IPv6 addressing strategies currently used and proposes a new replacement strategy to mitigate reconnaissance attacks. The new strategy is evaluated against some reconnaissance attack approaches. The experimental results confirm the effectiveness and validation of the new addressing strategy in terms of the mitigation of reconnaissance attacks.

In this study a novel four dimensional (4D) chaotic system is introduced. To prove chaotic behavior of the system, time series and phase portraits are presented. A novel pseudo random number generator (PRNG) application of the chaotic system is realized to show the system is suitable for engineering applications like encryption and data hiding. In order to realize PRNG, the chaotic system is discretized with numerical methods. The next step is selection of different number of bits from different state variables obtained from the chaotic system. NIST 800-22 statistical tests, the highest international standard, are performed for the generated random numbers to prove the proposed PRNG has sufficient randomness and successful results are obtained.

Measuring software maintainability is of vital importance for improving software product quality. Using a software quality model in the development life cycle, the quality of the system can be continuously evaluated and improved to reduce the maintenance cost. According to ISO/IEC 25010 Software Quality Models Standard, the maintainability characteristic of software product quality is composed of five sub characteristics; modularity, modifiability, reusability, analyzability and testability. This paper proposes a quality measurement model to evaluate the maintainability of software classes in terms of their reusability and modifiability characteristics in large-scale software systems. The model is based on software properties that are strongly related to reusability and modifiability, such as size, complexity, cohesion, coupling, and inheritance. First, our method categorizes metric values of software classes in the test system as low, medium and high. This categorization is done based on the average and median values for these metrics that are obtained from reference software systems. Then, the proposed measurement method uses the levels of the metrics to calculate the reusability and modifiability scores of each class in the system. The scores fall in one of the five categories; very low, low, medium, high, and very high. The developers of the software system can examine classes with low and very low scores and then refactor them if necessary. This continuous evaluation and refactoring during the development can increase the quality of the system and reduce maintenance costs. We applied our model on two largescale industrial mobile applications and discussed the results with the development teams of the systems. We saw that our approach could reasonably grade classes on their reusability and modifiability characteristics.

The main objective of this research is design and realization of a wireless, secure, remote monitoring, control and feedback systemusing GSM technology for the patient health. In this study, CRUD (Create, Read, Update and Delete) operations can be performed on a Windows Communication Foundation (WCF) server using the developed mobile application andMySQL database. This system also includes a ripped QR scanner that prevents the browsers from entering QR code information because a crypto QR definition of the patient's identity number was developed. All the patients’ assay results and their radiological views are recorded along their reports. Patients who need regular follow-up can send their daily, weekly and monthly results to the physician using this application. In an instant panic situation, this system can communicate to the 112-emergency services and by the help of a push-to-talk button, system can send the patient's instant location to the phone number indicated by short message service (SMS). If 112-emergency departments support the connection, system can also send this location information automatically to 112-emergency systems. Transmitted data is archived and visualized both on a mobile phone and on a central server. The experiments on the proposed system gave promising results that is accurate in scanning, clear in monitoring, intelligent in decision making and reliable in communication.

As known, web crawlers are programs that automatically browse on the web. Their purpose is to automatically navigate pages, saving source links that have target links, marking pages according to the words in those links, saving, indexing, collecting data to bring personalized ads, etc. Although the web crawlering algorithm is simple, it has various difficulties with respect to the existing pages on the web and the resulting amount of data. The semantic web works on generating computer readable data and is intended to overcome the quantity of data generated. Ontologies represent a pivoting source for semantic web applications. Ontology based crawlers scan the web by focusing on related web pages along with a specific ontology based on area ontology. The main advantage of the ontology based web crawlers over other crawlers is that no Conformance Feedback or Training Procedure is required to move wisely. In addition, both the number of documents and the more effective and efficient results will be obtained during the scanning process. As a result; The main advantage of an ontology based web crawler over other web crawlers is that it does not require intelligent, efficient operation and relevant feedback. In this study, traditional and ontology based web crawlers approaches and its infrastructure are examined. In addition, differences between ontology based web crawlers and traditional web crawlers have been investigated. A brief of literature summary on the subject has been included.

Neural networks (NNs) is used to solve many engineering and science problem. Generally, feedforward architecture is preferred and gradient-based learning algorithms are extensively operated to tune all parameters of NN iteratively. This training method is a conventional one, but training process takes a long time due to the slowness of gradient-based learning algorithms. This slowness has been an important drawback in their applications. To overcome this disadvantage, extreme learning machine (ELM) concept introduced to science community in near past. Essentially, ELM is a data-driven learning algorithm for single-hidden layer feedforward neural networks (SLFNs). This algorithm provides extremely fast learning speed. In this study, performance of SLFNs learned by ELM algorithm is investigated on the problem of highly nonlinear dynamic system identification. As a result of studies on selected benchmark problems in the literature, it has been seen that ELM may not provide a good generalization success due to randomly chosen the number of hidden nodes and weight parameters for inputs in SLFN. For both the training and the test data set, very poor results have been obtained and observed surprisingly during the above-mentioned studies. Here, a simple heuristic approach has been proposed in this study in order to eliminate this bad situation and the findings obtained with this approach are discussed. Based on the obtained experimental results, it has been shown that the proposed approach determines the optimal the number of hidden nodes and a reasonable random selection of input weights required for a good generalization performance.

The air transport has become the widely used option for the travel. The time saving and comfortable conditions encourage people to choose the airlines. The fierce competition and attractive market forced companies develop different pricing strategies to gain a competitive advantage. The ticket price, the charges for the luggage weight, special good carrying and seat selection are just many of the strategies developed by airline companies. The reaction of the customer is usually to choose the most economic option. Airline companies need a decision support system that will simulate the customer behavior against their strategies considering the strategies of their competitors. In this research we develop a simulation methodology for the domestic market in which we include different prices imposed by the airline companies and the buying preferences of the customers with the assumption that customer always choose the ticket with the minimum price. The airline companies then can analyze the consequences of their price strategies and expected strategies of their competitors.

Researchers have been studying to understand and classify biological signals for better diagnose diseases and developing assistive technologies. These technologies are sometimes making it possible to communicate in ALS (Amyotrophic lateral sclerosis) patients, sometimes possible to use our computer, faster and more efficient without using our muscular systems. The steady state visual evoked potential (SSVEP) approach currently provides the high performance and reliable communication for the implementation of these technologies. Performance is usually measured by Information Transfer Rate (ITR) and the most important factor affecting ITR is signal window length. In the presented paper a SSVEP based BCI (Brain Computer Interface) speller application is introduced and system performance is analyzed for different signal window lengths in experiments. The BCI speller has six box which has six letters in each box on the screen. The six letters in the selected box are distributed as one letter each box after the first selection by application. With the second selection, the letter which desired is displayed on the screen. The application contains Latin letters as well as Turkish letters. Experiments are performed on 3 healthy subjects. Subjects try to choose letter by focusing boxes which has flickering different frequencies. The minimum energy combination (MEC) method is applied to EEG segments that are different length in order to detect SSVEPs. The highest ITR value of 77.55 bit/min is obtained for subject 1 with 2 s signal window length. High accuracy and more useful a BCI system observed when system signal window length set 3 s.

Self-Adaptive Systems (SASs) are systems that monitor and adapt their behavior autonomously in response to dynamic state and environmental conditions. A typical architecture of SASs is constituted of a Manager (Autonomic) Sub-System that controls a Managed Sub-System. A well known architecture of the Autonomic Sub-System is the MAPE-K model. It is constituted of the Monitor, the Analysis, the Plan, and the Execution stages and the Knowledge Base. The major challenge of SAS is that all the stages are subject to uncertainty. Consequently, it has a significant impact on the adaptation quality. Currently, uncertainty is considered as a first-class concern in constructing Self-Adaptive Systems. However, few detailed works have been done about uncertainty in MAPE-K Control Loop. This paper intends to survey the most recent research on uncertainty in the MAPE-K using FRAMESELF architecture which is a detailed MAPE-K loop. Precisely, we present the sources of uncertainty in each process of the FRAMESELF model. In addition, we focus on missedsources of that we believe the community should consider.

In this study, a voice encryption application is realized by using a four dimensional (4D) chaotic system with single parameter. The main purpose of use of a single parameter chaotic system is reduction of computational load in order to run the voice encryption application on low performance hardware. Since the chaotic system is four dimensional, the system has four state variables and for every state variable different values of initial conditions can be used. This makes the key space length sufficiently long. In the application, the state variables are obtained with Runge-Kutta (RK4) method. The voice encryption is realized by XORing the obtained state variables with the voice data. The security performance of the voice encryption is proved by comparing the encrypted and original voice data in both time and frequency domain.

The Student Model is dedicated to personalize and to adapt the learning. With pedagogical strategy self-switching, the monitoring of the student model is the cornerstone of pedagogical strategy adapting. To efficiently achieve the monitoring operation, we propose a fine grained WildCAT based Observable Bayesian Student Model. On one side, it represents how the user relates to the concepts of the knowledge structure using the pedagogical component. On the other side, it integrates concept level sensors that results in an Observable Networks’ Sensors. This permits to ensure the collect of the instant student knowledge level. In addition, it uses a publish/subscribe communication model to notify the Student Cognitive changes to the monitoring component. On this side, the Monitoring Component subscribe as a receiver of appropriate cognitive changes. To experiment the likelihood and the usefulness of this model, a framework is constructed using WildCAT on a Student Cognitive Level.

On the first step, we discretize curves using the proposed adaptive method. Then, we construct Voronoi diagram of the discretized objects and process the obtained Voronoi graph such that redundant edges and cells are removed. Finally, the edges of the processed graph are approximated by Bezier curves giving the parametric representation of the final Voronoi diagram. The total complexity of the described algorithm is O(n log n) in average.

In the past two decades, human action recognition has been among the most challenging tasks in the field of computer vision. Recently, extracting accurate and cost-efficient skeleton information became available thanks to the cutting edge deep learning algorithms and low-cost depth sensors. In this paper, we propose a novel framework to recognize human actions using 3D skeleton information. The main components of the framework are pose representation and encoding. Assuming that human skeleton can be represented by spatiotemporal poses, we define a pose descriptor consists of three elements. The first element contains the normalized coordinates of the raw skeleton joints information. The second element contains the temporal displacement information relative to a predefined temporal offset and the third element keeps the displacement information pertinent to the previous timestamp in the temporal resolution. The final descriptor of the skeleton sequences is the concatenation of frame-wis e descriptors. To avoid the problems regarding high dimensionality, PCA is applied on the descriptors. The resulted descriptors are encoded with Fisher Vector (FV) representation before they get trained with an Extreme Learning Machine (ELM). The performance of the proposed framework is evaluated by three public benchmark datasets. The proposed method achieved competitive results compared to the other methods in the literature.

Today, breast cancer is the most common non-skin cancer affecting women. Because mammograms do not give clear findings until a certain age for the diagnosis of breast cancer, ultrasounds are applied as an imaging technique. Then, according to the findings in ultrasounds, imaging techniques like mammograms or other detection techniques are applied. Patient will be required mammograms if ultrasound findings look suspicious or the patient is above a certain age. Patients will have biopsy according to the mammogram findings and other risk factor values. Each step in this process will lead the patient anxiety, and expenditures. But the results of not performing these processes will lead one case of cancer and leads the patient more serious problems and expenditures. Therefore, every step of the process is vital importance to predict the most accurate information available. Computer-aided diagnostics (CADx) models are helpful in working on a huge number of variables, and related the risk factors and risk estimation together. Many CADx models provide support for experts by evaluating the mammographic findings and are used by radiologists to increase the detection rate of missed cancer patients. In this study, application of well-known data mining techniques is done on a public breast cancer data set. As a novelty, Migrating Birds Optimization (MBO) which is a fairly new metaheuristic is also applied on the same data set and the results are discussed. It is shown empirically that the MBO meta-heuristic presents preferable performance to the well-known data mining techniques.

- A complete knowledge of Tibiofemoral (TF) joint kinematics is essential in understanding the function of he al thy and pathological joint. The objective of the present study is to determine the six degrees’ translations and rotations of TF joi nt during 10-minute in-vivo creep loading while standing using Dual Fluoroscopic (DF) images. A computational model was develope d for the kinematics analysis of the right knee of a 24-year old female participant with healthy legs. Magnetic Resonance Imaging (MRI) was obtained for the unloaded joint and used for reconstruction of the knee joint model, including soft tissues. A high-resolution DF system was used to image the distal femur and proximal tibia during 10 minutes of standing. Braces were used to minimize flexions and rotations of the TF joint during the measurement. Translations and rotations of TF joint as functions of time were determined from the DF images with the JointTrack software. Coordinate systems were established for 3D model of distal femur and proximal tibia anatomically. Rotational and translational orientations of the TF joint were calculated based on these coordinate systems. The maximum relative rotations of the distal femur with respect to the proxi mal tibia during 10-minute creep with approximately half body weight were 1.167 degrees in varus-valgus rotation, 4.334 degrees in internal-external rotation, and 0.541 degrees in flexion. The results showed a vertical displacement of 0.234 mm with very small rotations during 10-minute standing. Finite element modeling of the joint is in progress.

In this study, we consider an intelligent placement of electrical materials such as luminaire, oven, dishwasher, washing machine, refrigerator, TV-phone socket, etc. for the appropriate places for drawing electrical installation diagrams. Electrical installation project drawings of the buildings are prepared on the architectural projects which are prepared by the architects. When the electrical materials as symbols are placed on the project, with the type of building, the type and size of the inner area, the purpose of use and most importantly other descriptive symbol drawings (named as “architectural furnishing symbols”) are taken into consideration. For example, if an oven symbol is found in a drawing part, then it means that this part most likely is a kitchen. Although any of one architectural furnishing has dozens of different symbols, they are basically similar to each other with small differences. In our application, "architectural furnishing symbols" are introduced to the system using artificial neural networks, then “electrical material symbols” are automatically placed according to the furnishing symbols detected at the site.

When the evolution of human being is analyzed, it is seen that almost all activities are developed by trial and error method. However, it is also known that these methods are not productive and cause much time loss. Therefore, various methods have been developed to solve the problems encountered in different situations. As to educational activities, they mainly have quite different qualities than others. In general, education and training is done collectively by bringing people at the same level together. Although we accept individuals who are brought together of the same nature, this is not a very correct approach in many cases. In fact, people have different levels of knowledge and experience. Scientific studies have even shown that each individual's learning method differs. Therefore, whatever method is used, it is difficult to obtain the desired efficiency in collective learning. In this study, a new learning method based on interactive learning and knowledge based learning systems has been developed with reference to the personal differences that emerged during learning. With this method, first, the strong and weak aspects of the person related to the subject to be learned are determined and then the interactive learning is provided with the designed interface. In this learning method where learning is performed at different periods with asynchronous learning techniques, creating permanent learning by taking individual differences into account is the ultimate goal.

Turkish Sign Language (TSL), which is a mother tongue of hearing-impaired individuals, is a natural language. Expression patterns used in this language are carried out within the settings of the rules of the language. In this study, a textual interpretation system from Turkish to TSL was developed. Within this context, a corpus consists of 230 sentences was composed. Beside the sentences included in the corpus, also the interpretation of the sentences entered by the user interactively can be made. The rules of both languages were taken into consideration in the interpretation of the sentences. Firstly, Turkish sentences were parsed to words and then, morphological analyses of the sentences were performed withZe mberek. As a result of the morphological analyses, root/stem of the words and the affixes attached to the words were determined. Some affixes are not considered as necessary in TSL. Therefore, the affixes which are not considered as necessary should be determined and ignored within the interpretation. Moreover, various rules were constructed for the transformation by considering the results of the morphological analysis rules and usage samples. Descriptions related to 489 signs and 6 non-manual signs were made in order to express the sentences included in the corpus in TSL. The number of the signs out of 489 were as follows: 81 static, 408 dynamic, 334 single, 155 repetitive, 6 sign union and 2 word combination. 6 non-manual signs were as fol l ows; baş önde (head ahead)" bö", baş yukarı da (he ad up) "by", kaş yükseltme (eyebrow raising) "ky", kaş i ndi rme (e yebrow l owe ri ng) "ki", past aspect "di" (past tense suffix) and continuous aspect "yor" (present continuous tense suffix). Usage numbers of the nonmanual signs were as follows: 66 "bö", 12 "by", 38 "ky", 40 "ki", 94 "di" and 31 "yor".

In the empirical sciences, experiments are carried out in the laboratory so that the results may be applied in other locations where the conditions are the same as in the laboratory. Hence, it should be possible to establish certain causal statements in the laboratory, which can be transported to real-world environment. In the present paper, experiments were carried out on wireless sensor networks in the laboratory and the results were transported to environments where experimentation is impossible. The tool Tetrad was used to arrive at the causal directed acyclic graph for the wireless sensor network in the laboratory. The concepts of selection diagram, the principle of transportability and the condition for failure of transportability are discussed. The applicability of transportation algorithm for typical environment and also the failure of the same are analyzed. Simulations are carried out using the simCausal package in R programming and the validity of the probability expressions transported by the transportation algorithm are shown to be correct.

In this paper, performance of joint transmit and receive antenna selection in cooperative MIMO channels is investigated over Rayleigh fading environments. A cooperative MIMO communication scenario in which all of the terminals are equipped with multiple antennas is considered where source want to transmit data to the destination with the help of the relay. The techniques developed in literature to combat error propagation effect in digital relaying networks such as cooperative maximal ratio combining (C-MRC), virtual noise (VN) based detection and selective relaying (SR) are exploited in this study to obtain new antenna selection criteria for cooperative MIMO systems. Only one antenna is selected and activated at each of the three terminals in a manner to minimize the end-to-end bit error rate (BER) of the overall system. This approach eliminates the requirement of space-time signaling in system design and reduces the complexity and cost by minimizing the number of the required RF chains in the network. Unlike most of the studies in the literature, we assume that the direct link between source and destination exists. Numerical results have shown that a diversity order of (nS + nR) * nD can be achieved for VN and SR based transmissions where nS, nR, and nD are the total number of the antennas at the source, relay and destination, respectively. Among the considered schemes, the best performance is obtained in case of SR based system model.

The main purpose of the semantic web is to develop standards and technologies that will enable well-defined and linked information and services to be easily computer-readable and computer-understandable in the web environment. Linked data is one of the approaches used to acquire meaningful integrity by gathering data-related data collections by creating semantic links between the web pages that make up the content of the semantic web. Linked data is based on RDF (Resource Description Framework) technology. RDF is a data model that provides space-independent formal semantics with respect to chart resources. In a linked data application, the most important decision point is how to access the linked data. Linked data crawler is a program that explores linked data in web by tracking RDF links. In this work, DBLP (Database Systems and Logic Programming) data set is used as a source of Linked Data. DBLP gradually expanded toward all fields of computer science. An example will be presented related to pageRank sorting of RDF resources in the DBLP dataset. As a result; the search area has shrunk and search results have improved.

In this study, Artificial Atom Algorithm, which is a new meta-heuristic algorithm approach, have been used to calculate the threshold value which is frequently performed in image processing applications. The entropy-based method has been adopted for the target function which is common in the meta-heuristic algorithms. For this aim, Shannon entropy and a new entropy method, Fractional Order Entropy, have been used. It is seen on standard test images that the Artificial Atom Algorithm can be applied to image processing applications. In addition, the results of the application were supported by comparing the values produced by certain parameters of fractional entropy with the values produced by Shannon Entropy.

New and less energy consuming methods are developed to reduce the increasing heating costs day by day. Heat transfer method is one of the most commonly used methods for heating an environment. The amount of heat required to heat an environment in a heat transfer technique is found by the amount of heat lost from the environment. In this study, artificial neural networks were used for estimating the monthly heat demand for the heating needs of a greenhouse in Elazığ province with 2017 meteorological and spatial data. The amount of heating has been tried to be estimated using the MATLAB program with the lowest error. Heating Degree-Day (HDD) values and latitude, longitude and altitude data were used for analyzes to be made in the artificial neural network model. It has been estimated that the heat requirement for the heating of the greenhouse is lower than the heat requirement for the heat transfer method in the designed artificial neural network model.The artificial neural networks model has been found to be a useful method for studying the heating of greenhouses.

Text classification, which is a sub-field of the natural language processing, is utilized for the solutions of problems in various areas. One of these areas is the author detection in written texts. When a person writes a text, he or she makes several marks due to the spelling characteristics. Author detection or recognition means that ownership of the text is questioned by comparing these spelling features. Different features belonging to the author can be extracted from texts and many comparisons can be made. In this study, author recognition was performed using bigram, trigram and quadrigram frequency property with the Naïve Bayesian approach for decision making. 120 different Turkish books written by 20 Turkish authors in different distributions were studied. Initially, the authors' bigram, trigram and quadrigram frequency properties were extracted from the books. Then, the comparison of the n-grams performances attained by Naïve Bayesian method is examined through this paper.

Recognition and interpretation of human activities are very interesting and hot topics that are frequently studied in the field of computer vision. Especially with the advent and development of the Microsoft Kinect depth sensors, the expansion of the study fieldhas gained momentum in the positive direction. Thanks to RGBD cameras, which also provide depth information in addition to the RGB image, researchers benefit from many advantages in terms of privacy, accuracy and precision. In this study, automatic segmentation of repeated 3D human activity is proposed. A public dataset containing the repeated action sequences are recorded using the RGBD camera. The action sequence in this dataset includes similar and different action information. In order to identify and label each action in sequence, it is necessary to perform the segmentation process. To be able to perform a successful segmentation process, the data must be preprocessed to remove noise. For this purpose, a total variation based noise removal method is used. Human action recognition and detailed error analysis can be performed through the segments derived from the output of this work.

İngiltere’nin AB’ye girişi sancılı olmuştu. İki kez Fransa tarafından veto edildikten sonra 1973’te, o zamanki adıyla Avrupa Ekonomik Topluluğu’na üye olan İngiltere, içine girdiği andan itibaren en kritik konularda Birlik için hep sorun oldu. Ekonomik bütünleşme için son derece önemli iki konu olan Schengen Alanı ile Avro Alanının dışında kalmayı tercih eden İngiltere, siyasi konularda da sık sık Almanya-Fransa eksenindeki ülkelerle ters düştü. İngiltere’nin AB’den çıkış tartışmalarının hız kazanması Aralık 2009’da yürürlüğe giren Lizbon Antlaşması’ndan sonradır. Brexit, Birleşik Krallık’ın Avrupa Birliği ile ilişkilerinde en önemli dönüm noktası olmuştur. Bu nedenle, Brexit’e giden süreci, nedenlerini ve sonuçlarını incelemek konunun daha iyi anlaşılmasını sağlayacaktır. Referandum, arkasında bölünmüş bir ülke bırakmıştır. Özellikle İskoçya ve Kuzey İrlanda'da gençler ve kentsel nüfus AB'de kalmayı tercih ederken, büyük metropol alanlarının dışında yaşayan daha yaşlı ve az eğitimli nüfus İngiltere’nin AB’den ayrılması yönünde oy kullanmıştır. Referandum sonrasında Avrupa’nın geri kalanı şok içinde ve güvensiz bir durumda kalmıştır. Kimin kazandığının tam olarak belli olmadığı bir referandumun ardından, Brexit’in sonucunda da ne olacağı tam olarak belli değildir. Referandum neticesinde İngiltere tarafından elde edilen siyasi pozisyon, Birleşik Krallık'ın ve belki de AB'nin, dünya siyasetinde egemenlik iddiasını bırakması sonucunu doğurabilir. Bu çalışmanın amacı; AB üyeliğinin devamının İngiltere açısından ekonomik getirileri açıkça ortadayken Brexit nasıl gerçekleşmiştir? Birleşik Krallık’ın AB’ye tam üyeliğine ilişkin alternatifleri nelerdir? Antlaşmasız bir ayrılığın taraflar açısından sonuçları neler olabilir? sorularının yanıtını bulmaktır.

In large scale software applications, bug localization is a difficult and costly process. Many issues or bugs may be reported at both development and maintenance phase of software development lifecycle. Hence, it is important for developers to discover the location of the bug. In general, source codes and bug reports are used for identifying bug location with the help of Information Retrieval (IR) techniques. In this paper, we present an IR-based bug localization approach named BugSTAiR that uses structured information of source files, source code history, bug reports and bug similarity data if exists. To do best of our knowledge it is the first system developed for JavaScript source files. The experimental results show that accuracy of the system is promising (~%30 on Top 1) on file level bug localization.

With the increasing of data size in recent years, processing and analyzing of the big data has become difficult. Therefore, interest in this area has also gone up. In 2006, Geoffrey Hinton, the pioneers in the field of machine learning, developed a deep learning model at the University of Toronto. The basis of the deep learning model is based on the use of a large number of hidden layers in artificial neural networks. Previously, increasing the number of hidden layers in artificial neural networks, deepening the network, was not preferred because it caused complexity in calculation processes. Deep learning that provides a nonlinear transformation of the big data can model complex relationships with a multi-layered structure. As this model provides more comprehensive attribute learning, the classification becomes more successful. For this study, Convolutional Neural Network (CNN) model is represented for the large-scale image classification. CNN is the most widely used deep learning model in feature learning, recognition, and classification. In order to obtain a powerful image classifier, there should be large amount training data. Because of that, data augmentation techniques are used to boost the performance of the deep networks. In this study, data was increased using image augmentation methods that create artificial training examples through different ways of processing techniques such as adding noise, rotating, shifting, shearing, and resizing. The data that consists of car photos taken from the rear and are provided from the literature are separated into 40 categories. Finally, the classification performances using different deep learning CNN models such as AlexNet, VGG16, and VGG19 are evaluated and experimental results are reported.

In the last decade, technological innovations and a changing economic and regulatory environment have resulted in a renewed interest for distributed generation. In most cases distributed generation systems are represented in the form of autonomous energy centers, since the connection of distributed generation to centralized electrical networks is being limited to the lack or imperfection of the regulatory framework and effective means of controlling technological regimes. In this paper is carried out a comparative analysis of the operation principles and options for connecting to the distribution network of autonomous power plants using different types of distributed energy resources. While connection of distributed energy resources to distribution network, one of the main tasks is distribution of loads between generating capacities. An algorithm for solving this problem is also presented in the paper.

By the development of technology, image classification algorithms frequently use to identify land use and land cover of any area in remote sensing studies. Due to the diversity and complexity of land cover on the wetland areas, it is quite difficult to obtain accurate results related to the earth's surface. The main purpose of this research is to compare the overall accuracies of object based and pixel based image classification methods. Arslantaş Dam Lake is structured on Ceyhan River for irrigation, flood control and electricity generation in Osmaniye province. In this study, Landsat-8 LDCM satellite image of Aslantaş Dam Lake with spatial resolution of 30m, acquired on December 29, 2017 was used. Firstly, image was classified by pixel based classification with support vector machines (SVM) method. After that, image was reclassified by object based classification with K-nearest neighbour (KNN) method. Five classes namely lake, agricultural area, soil, vegetation and building area were determined by using these algorithms. Ground truth data were gathered from aerial photographs, available maps and personal informations. Finally, overall accuracies of these methods were compared. It is observed from the classification results that object based KNN method provide higher accuracy than the other classification method.

In parallel with the development of the technology, the storage of the data more easily and quickly and the faster processing on the stored data can make an important contribution to the creation and analysis of networks of coexistence. Complex networking plays an important role in analyzing and revealing common characteristics and structures of connected clusters depending on various characteristics. In this study, a network of association between male tennis player in the Australian Open, the French Open, the US Open and the Wimbledon tennis tournaments, known as four major international tennis tournaments between 2000 and 2017, has been established.While each tennis player is defined as a node in the network of associations created, the competitions of the tennis players with each other are defined as the links connecting these nodes. The universal principles of complex networks such as scale-free, small world, clustering have been examined. Furthermore, through Gephi software, the structural characteristics of networks are visualized by using the data obtained from this association network. As a result of the study, it was seen that the networks among the tennis players struggling in the related tournaments were carrying real world network characteristics and that the data obtained from these networks can be used for network analysis.

Today, with the development of information technologies, studies on the evaluation of relations between people, objects and events to put it simply relations between creatures and facts have taken place among general topics. As the data related to the relationships between creatures and facts continue to increase and become storable together with developing technology, new methods are being developed for analyzing and evaluating these data. There are both semantic and structural relations within the obtained data stacks. Complex network analysis is one of the most common methods used to reach semantic relationships as a result of analyzing and evaluating these relations. In this study, a network was formed among the teams who competed in the UEFA Europe League between 2004-2017 by using the data of football competitions played after the groups. As a result of the evaluation, different categories such as last 32, last 16, quarter final, semi final and final matches are analyzed and the similarities of the networks to the real world networks are compared with the data obtained about the network structures. As a result of the study, it is observed that the teams that compete in the UEFA Europe League are similar to the real world networks.

Existing networking systems are hardware-based and rely on inflexible architectures. In recent years, Software defined networks (SDNs) has emerged as a new paradigm for nextgeneration networks. SDNs are proposed to separate control plane and data forwarding plane in the traditional networks to reduce the increasing complexity of the network equipment. This separation enables a programmable and flexible hardware infrastructure via OpenFlow protocol and provides great opportunities in terms of reducing operating cost, simplifying network management tasks, gathering network statistics, and accelerating innovation. Logging is a structure that records the events of a system and the users in the system. With logging operations, the actions making by each device can be recorded. Especially in places where more than one person connects to the internet such as hotels, cafes, restaurants, student dorms and companies etc., it is necessary to monitor and take logs of the events. Already, by the Law No 5651, to combat certain crimes committed on the internet, it has become obligatory to take logs to institutions or people who provide collective internet services. In this paper, a logging and monitoring system has been designed and implemented. For logging and monitoring proceses, sFlow, OpenFlow, Floodlight, Open vSwitch, node.js, and MySQL technologies have been used. sFlow technology is used to monitor the networks. sFlow standard gives complete visibility into the use of networks enabling performance optimization, usage, and defense against threats. OpenFlow is a protocol used in SDN environments to enable the SDN controller to interact with the data forwarding plane of the network devices. Floodlight software is used by SDN controller for network operations. Open vSwitch software which enables to handle the traffic loads is installed at Raspberry Pi 3 hardware. The obtained results show that the proposed system can take the flowtable records, transfer the records to node.js via sFlow, and save the records to MySQL via node.js. Finally, the network traffic is successfully monitored and logged.

Geostatistical techniques had both the capability of producing a prediction surface and provide some measure of the certainty or accuracy of the predictions. Kriging method depended on mathematical and statistical models. Kriging was an interpolation that can be exact or smoothed depending on the measurement error model. Kriging used for statistical models that allow a variety of output surfaces including probability. We used an instrumental catalog for Ms≥4.0 magnitude between 1900-2017 period. Additionally, Kriging method fitted a mathematical function to a specified number of earthquakes or all earthquakes within a specified radius, to determine the output value for each region. We have used

Network security has become one of the most important issues in today's world. Along with the widespread use of the Internet, corporations and companies share important confidential information over networks. The protection of this information, which may lead to serious harm if third-parties have access to it, is vital. Moreover, with increased cyber attacks, corporate or private networks are under serious threat. Increasing the security of networks is of vital importance, because corporate networks are especially critical to national security. In this study, necessary protocols, equipment, technologies and necessary precautions have been investigated in order to make data communication in virtual private networks, which is one of the most used network technologies today, to be done safely.

Direction of gravity is a natural way of orienting oneself in an unknown environment. Human beings do thi s wi th equilibrioception. It would be beneficial to estimate the directi on of gravity from a single image for many tasks such as autonomous driving and augmented reality where the knowledge of location of the agent is very important. Extracting this knowledge from an image usually requires a reference to be identified. For example, a traffic light can give away the direction of gravity as it has to be placed in an environment in a specific way with respect to the gravity. Reference-based approaches require a lot of hand modeling for solving the problem. When there are a lot of images with ground truth data is available, one can model these references implici tly using machine learning techniques. We propose to use a set of images along with readings from inertial magnetic unit (IMU) taken from a smart camera observing an indoor environment. This data includes a lot of images as well as ground truth labels for gravity direction extracted from the IMU readings. The data is fed to a convolutional deep neural network to estimate the gravity directions formulated as regression as well as classification problem. We show that this modeling works quite well with a fe w hundred images when we formulate the estimation as a classification problem. The details of the networks trained and the results obtained are presented in depth. Further research with more images but with less accurate ground truth data is underway.

The technology to calculate the fire and failure rate of the glass from the glass line in the glass factories that are manufactured is facilitated by the technology. Waste and mistakes must be identified and improved for product and service quality. One of the methods used to calculate these rates is Failure Mode Effect Analysis (FMEA). The FMEA technique is a very powerful numerical analysis technique for preventing errors before they occur. In this study, a sample application of the Process FMEA study, one of the FMEA variants, was carried out for the glass sector. The problem to be addressed is defined as determining the error and waste rates of the glass from the thermopane line in a quality oriented business with the Perfect Scanner machine to reduce these ratios and increase the productivity. Types of errors obtained from Perfect Scanner data; the questionnaire survey conducted in the production area and the feedback from the customers were collected in 5 issues. These; scratches, stains (fingerprints), coating failure, stains between laminating glass, air bubbles. We determined and implemented the changes that will improve the process to eliminate or reduce the reasons for the types of errors encountered. Thus, by measuring the performance of the thermopane line of this company which has an important place in the glass industry, the negativity of the performance in production is minimized and customer satisfaction is increased.

Data collection, data retention and analysis are becoming more and more important every day because of the fact that technology is involved almost all our life. The processing and analysis of the data can become more difficult with increasing precision. In three-dimensional surface modeling, due to the increase in sensitivity and data size depending on the surface state and extent of the surface, collecting and processing the data may become difficult. As a solution to this situation, we can see that Computational Geometry is used extensively. Computational Geometry derives intermediate interpolations by taking the start and end data as references instead of keeping each data separately. In this way, it is possible to model by determining intermediate values based on the mentioned reference points. There are various methods in Computational Geometry such as intersection detection, point position and triangulation. According to the needs, a solution way can be produced by various geometric computations. In our study, "Delaunay Triangulation" which is the most used type of triangulation methods will be examined.

This paper describes an antenna design that is suitable for microwave imaging and radar applications. Microwave imaging technology has attracted many interests nowadays and it has been used in a variety of applications such as: non-destructive testing and evaluation, through-the-wall imaging, concealed weapon detection at security check points, structural health monitoring and medical imaging. Similarly, radar-based applications have been popular in many areas. The basic idea of using microwave imaging and radar systems is to transmit electromagnetic waves from a transmitting antenna to the target material and receive the scattered waves at a receiving antenna. For this reason, the choice of the antenna plays an important role for the system. There is a need for compact sized, low cost and high efficiency antennas which can radiate ultra-wideband signal to transmit short pulses. Furthermore, these antennas should have similarly end-fire radiation pattern to obtain good resolution of the produced images for using both in imaging systems and radar applications. In this study, firstly a conventional compact-sized rectangular patch antenna is designed. Then, various optimizations are performed on that antenna by using High Frequency Structural Simulator (HFSS) software. After that, this antenna is fabricated and tested with Vector Network Analyzer. The fabricated antenna has a simulated and measured bandwidth from 4 GHz to 9 GHz for |S11|<10 dB, respectively. The return loss results show that the good impedance matching is obtained through the working frequency band. The proposed antenna has nearly stable end-fire radiation patterns throughout the frequency range. All of the results exhibit that the designed antenna can be used in high range radar applications and is a good candidate for microwave imaging applications.

Easy availability and cheapness of microcontrollers, intelligent sensors and wireless technology equipments have paved the way for different engineering and industrial applications of control systems. Conventional closed greenhouses, which are one of these spaces, have been converted into high-tech plant production units. A low-cost greenhouse automation system which can be monitored at computer environment by virtue of an interface created in Matlab GUI programming language is proposed in this study. To this end, a model greenhouse system taking into consideration temperature, air humidity, light intensity and soil’s physical quantities as input parameters was made. The output parameters used in the model greenhouse were heating, ventilation, irrigation and lighting control. It was determined that the system created by comparing with conventional control systems, was more advantageous in terms of usage, monitoring and programming. Ease of use was provided to the user due to control and monitoring of physical quantities in the greenhouse by virtue of the Matlab GUI interface. The most prominent characteristic of the offered system is that it can easily be used for other agriculture and poultry stockbreeding areas by making small changes in the software infrastructure.

Metamaterials are man-made artificial materials that are not a natural material but rather have different electromagnetic properties. One of the features mostly studied in recent years is that it nearly absorbs all incoming electromagnetic waves. These features make it possible to invisibility against remote sensing systems. Thus, the radar cross-section area (RCA) representing the radar visibility can be reduced by covering the target plane with metamaterial. As a first step in this work, the unit cell of the metamaterial, which has a resonance effect, is designed to achieve high absorption at 6.0 GHz. Then, using the unit cell's scalability feature for this metamaterial, two more-unit cells with resonance effect at 5.0 GHz and 7.0 GHz were designed, respectively. Subsequently, all three were brought next to each other and super-cell structure was introduced. The structure obtained shows 94.62% absorption at 5.08 GHz, 99.95% absorption at 5.98 GHz and 90.42% absorption at 7.02 GHz, respectively, in the C band region (4-8 GHz).

Unmanned Aerial Vehicles (UAVs), are air aircraft that can fly autonomously without human control or that can be controlled by a ground station. In parallel with the technological developments of the present day, it has been observed that the use of UAVs is also greatly increased. In this context, new working areas were needed together with the widespread use of UAVs. As a result of the researches, the autonomous control works was seen to become the foreground. Within the scope of this study, an autonomous landing system has been implemented for UAVs. The images taken with the help of the camera located at the bottom of the UAV are subjected to image processing techniques on the Linux based operating system to determine the landing track. In the scope of the study, the landing station detected is a circle with a "H" in the middle. The letter "H" on the landing station can be changed color according to the location. For example; the landing station can be red in football ground, can be blue in empty ground. Images taken from the camera are subject to the image processing technique. First of all, the image is removed from noises. Then, it is classified according to the “H” letter color on landing station. Pixels which are same with "H" letter are changed to white color, others changed to black color. So that, it is determined how many shaped has been found. The shapes are ordered according to their size and compared with the landing station. If the similarity rate is over 75%, the target is determined.Once the determination, the altitude of UAV will gradually decrease and the image acquisition and measurement process will be repeated until it reaches a desired position. After arriving at the desired position (Eg z<=20 cm), the UAV performs descent by stopping engines.

One of the purposes of video surveillance systems is to detect anomalies which are unexpected situations at a certain location or at a frame. Anomalies can be related to motion or appearance according to its spatial position. In this paper, we propose an anomaly detection system based on spatio-temporal features. Features from Accelerated Segment Test (FAST) is used for detection of corners location. Optical Flow magnitude and orientation of these points is used as spatio-temporal features. A grid is to the frames to neutralize the effect of proximity to the camera. Normal patterns are clustered with an unsupervised neural network so called Self-Organizing Maps (SOM). In test videos if extracted features cannot model with normal clusters, associated grid cell will be marked as anomaly Keywords - Video Surveillance, Anomaly Detection, Features from Accelerated Segment Test (FAST), Optical Flow, SelfOrganizing Maps (SOM)

In the literature, machine learning algorithms are frequently used in detecting anomalies in network traffic and in building intrusion detection systems. Deep learning is a subfield of machine learning that trains a computer-based system to perform humanitarian tasks, such as disease diagnosis, speech recognition, image recognition, fraud detection, and making predictions. In the experimental study, NSL-KDD dataset was used for evaluating the performance of the proposed deep learning based DDoS detection model. NLS-KDD dataset contains normal network traffic and 23 different DDoS attacks that consists of 41 features. In the experimental study two different experiments are carried out. Firstly, the proposed deep neural network detected the Dos attacks with 0.988 classification accuracy. In the second experiment, the number of features of NSL-KDD is reduced to 24 by examining the previous feature reduction research on NSL-KDD dataset. The proposed deep neural network classified the all cyber-attacks with 0.984 classification accuracy. The 10-fold cross validation is used for all experiments. As a result, the proposed deep learning based DDoS detection achieved good performance.

Inventory control models are one of the most mature fields in the area of supply chain management but it is not obvious how to extend inventory control models under different types of problems where each problem has specific features and includes many different limitations and constraints. In addition, the dynamism of the real-world interactions occurring in inventory control systems should be modeled with much details, realities, and complexities. At this point, Simulation Optimization (SO) models along with modern computing power provide a significant opportunity to respond effectively in a dynamic and stochastic environment. To remain competitive and viable in today’s business climate, SOcan be explicitly taken into account as a complementary tool. In this study, SO is used to develop a multi-objective search for the inventory control system with supplier selection where objectives of the SO model are minimizing total supply chain cost and maximizing average service level. The optimal values of the initial inventory, re orde r point, and order-up-to level for supply chain members are determined by proposed SO model. The proposed model has an ability to analyze dynamics of the supply chain members and to transform it into a clear structure for supply chain decisions. This is very important in real-world settings because proposed models lead to a large number of variants to manage a wide range of decisions in the supply chain.

Social media platforms such as Twitter have grown at a tremendous pace in recent years and have become an important source of data providing information countless field. This situation was of interest to researchers and many studies on machine learning and natural language processing were conducted on social media data. However, the language used in social media contains a very high amount of noisy data than the formal writing language. In this article, we present a study on diacritic restoration which is one of the important difficulties of social media text normalization in order to reduce the noise problem. Diacritic is a set of marks used to change the sound values of letters and is used on many languages besides Turkish. We suggest a 3-step model for this study to overcome the top of the diacritic restoration problem. In the first stage, a candidate word producer produces possible word forms, in the second stage the language validator chooses the correct word forms and at the final word2vec is used to create vector representations of the words and make the most appropriate word choice by using cosine similarities. The proposed method was tested on both synthetic and real data sets, and we achieved a relative error reduction of 37.8% in our data sets compared to the previous study with an average of 94.5% performance.

As an instrument of democracy, voting is a critical issue. Although paper-based voting systems are still used commonly, e-voting systems have started to substitute under favor of improvements in the technology. This situation gives rise to need for secure, reliable, and transparent e-voting systems to make people trust. To do this, there are some security requirements that should be concerned and satisfied such as privacy, fairness, verifiability etc. This study has an educational intuition that analyzes those requirements, theoretical background information related to cryptographic schemes behind them and creates a place-based e-voting design which was implemented for kiosk voting. As a contribution, Paillier homomorphic cryptosystem is used in our system. Moreover, our study includes a detailed criticism for the implemented system in terms of chosen cryptosystems and design modules with security and e-voting requirements.

Visible light communication (VLC), popularly known as light fidelity (Li-Fi), is a promising alternative to overcome the limitations of radio-wave communication. VLC is a green technology which uses light-emitting diode (LED) illumination to transmit data without needing fibre cables. VLC is applicable for both indoor and outdoor communication. In this study, we investigate the effect of sandstorms on VLC via simulating a vehicular-to-road VLC (V2LC) outdoor application. Sandstorms are a weather phenomenon which frequently occurs in the Arab peninsula and other parts of the world; in this context, researchers have not thus far addressed the effect of sand particles, which absorb and scatter light, on VLC. Our simulation is conducted using MATLAB software, and the results show that the effect of sandstorms on VLC is similar to that of fog and rain as investigated by other researchers. However, sandstorms are also different in terms of the nature of sandstorm particles, with different sizes and refraction indices when compared with rain and fog particles. We also find that high-density-clay sandstorms, among other types of storms, most severely affect VLC communication and limit the transmission range. Other low- and medium-density storms less severely affect VLC while exhibiting a relatively larger communication range.

This article attempts to solve the problem of efficient design of proportional+integral+derivative (PID) controller applied to automatic voltage regulator (AVR) by employing recently introduced symbiotic organism search (SOS) algorithm for the first time. SOS is a metaheuristic proved recently to be promising by benefitting from the idea of imitating natural phenomena of interactive behavior seen among organisms living together in a similar environment. PID controller design needs proper determination of three control parameters. Such a design problem can be taken as an optimization task and SOS is invoked to find out better controller parameters through the new cost function defined in the paper, which allows to evaluate the control behavior in both time-domain and frequency-domain. For the performance analysis, distinct analysis techniques are deployed such as transient response analysis, root locus analysis and bode analysis. The efficacy of the presented technique is widely illustrated by comparing the obtained results with those reported in some prestigious journals and it is shown that our proposal leads to a more satisfactory control performance from the perspective of both time-domain and frequency-domain specifications.

— Concrete steel bars used in the construction sector are produced according to Turkish Standard, “TS 708 Steel for The Rainforcement of Concrete- Reinforcing Steel”. Suppliers, produce concrete steels using the Tempcore system that provide the desired properties by developing processes for high safety and low cost. The tempcore system is a process of giving a certain amount of water to the surface of the concrete steel bar coming from the finish rolling mill. In our study, our purpose is estimating the mechanical physics properties of the concrete steel bar produced by the tempcore system which is most common method with multiple linear regression. Generating to elements of chemical composition which are carbon, manganese and silica, also parameters (water discharge, size etc.) affecting the strength in the rolling process were determined as “independent variables”. “The Yield Strength” and “Tensile Strength” as a dependent variable is estimated by the Multiple Linear Regression Method. As a result of the study, it is aimed to reduce the amount of scrap product that is erroneous and/or to be released to the waste by preventing the production faults by predicting which yield values of the input variables such as water flow will yileding in the chemical composition.

Social network analysis investigates relationships in a networked structure in order to interpret the roles of individuals and evaluate their respective importance. The common approach is employing graph theory that models the network as a graph data structure. Graphs are mathematical abstractions to model pairwise relations between objects. A graph is comprised of nodes connected with edges. While nodes indicate individuals in a network, edges signify relationships or interactions. In this paper, we evaluate the research performance of the European countries considering the research activities within the framework of European Cooperation in Science and Technology (COST). Founded in 1971, COST is the oldest and widest scientific intergovernmental framework in Europe supporting 37 countries including Turkey. COST can be considered as an incubator to set up interdisciplinary research networks since it provides support for network activities such as meetings, training schools, short scientific exchanges, etc. but does not fund the research itself. Therefore, we believe that the research network under COST can be a good indicator to analyze relationships between countries in research activities and evaluate the research performance of the countries. In this paper, we considered research actions funded by COST between 2012-2017 and evaluated research performance of the countries according to their participations andinteractions. To assess the performance, we modeled the relationships between countries on a directed graph and applied centrality analysis which is a common approach to evaluate the relative importance of a node within the network. Each action is coordinated by a management committee which is composed of a chair and at most two delegates per participant country. In the graph, each participant country is denoted with a node. We classify the countries according to their roles in the action. Since the proposer of the action becomes the chair, usually,we regard the country of the chair as a gateway to access the action. Therefore, to signify the relationship between two countries, a directed edge is added from the participant country to the respective country of the chair. Note that several projects were considered over a span of 6 years and multiple interactions between two nodes are indicated as the edge weight.

Recently, object tracking methods based on deep learning have shown great successes. Using deep neural network methods allows following the object even in highly complex scenarios by learning more details of the object in the video and the object motion model. The developed network architecture needs to be trained with a powerful dataset. The variety and size of the selected dataset affect the success of object tracking methods’ results directly. Some object tracking studies have also used image datasets to obtain the diversity in the training set in addition to the video dataset. The object in the image has gained some kind of artificial motion/action between the two images by making the certain rotational or translational movements. But the uses of this technique brings out the question of whether the object has gained a right action or not. In this study, a new perspective is introduced to provide the data the diversity which is required by deep learning-based methods. In this paper, ADnet, which is a deep learning based object tracking method, is used to test our new perspective which is mentioned above. For the training of the ADNet method, color spaces such as HSV, L*a*b*, NTSC, YCbCr, inverted HSV (converted to HSV channeled by taking BGR instead of RGB) were analyzed. As a result of the analysis, HSV and inverted HSV (IHSV) color spaces have been found out to provide stronger and more varied training dataset. Moreover, in order to prepare a proper training set for the object tracking, two different datasets were created with the videos taken from Vot2015 and Vot2014 datasets. Six different training sets were created for each group by translating them into RGB, HSV and IHSV color spaces. A separate ADNet network architecture was trained for each training set. Tests were carried out for each method with the dataset, which included 61 videos. This test dataset includes some videos which are not used in training dataset. In conclusion, it was found that stronger training sets could be created by applying different color transformations such as HSV and IHSV to strengthen the training set.

In this paper, the magnetic field exposure analysis of a human body due to underground power cables is carried out as the simulation study. Simulations are implemented through a finite element method (FEM). Human body is modeled as a two layered cylinder. Upper layer of the cylinder is selected as an average skin tissue and the inner layer is formed as an average muscle tissue with realistic values at an extremely low frequency (ELF) region. Shielding is applied as the mitigation technique and aluminum (Al) is used as a shielding material. The thickness of 1, 2, 3 and 4 mm shielding materials are applied, respectively. Evaluations are implemented with respect to the magnetic flux density and the induced current density. 4 mm shielding which is the thickest material used simulations shows the best shielding results to mitigate the magnetic flux density and induced current density. The worst shielding is obtained for the 1 mm thickness of the material, as expectedly. Furthermore, as the distance of the source increases, both magnetic flux density and induced current density decrease. In other words, these parameters depend on the distance between a source and observation points. Different induced current density values of skin and muscle are observed due to the different electrical properties of tissue. Assessments have been done according to exposure limits published by the wellknown organizations.

As known, attribute selection is a method that is used before the classification of data mining. In this study, a new data set has been created by using attributes expressing overall satisfaction in Turkey Statistical Institute (TSI) Life Satisfaction Survey dataset. Attributes are sorted by Ranking search method using attribute selection algorithms in a data mining application. These selected attributes were subjected to a classification test with Naive Bayes and Random Forest from machine learning algorithms. The feature selection algorithms are compared according to the number of attributes selected and the classification accuracy rates achievable with them. In this study, which is aimed at reducing the dataset volume, the best classification result comes up with 3 attributes selected by the Chi2 algorithm. The best classification rate was 73% with the Random Forest classification algorithm.

Computational forensic is a far-reaching field for criminal and civil laws in this age. Aim of this project is to develop an educational tool to analyze persistent storage devices to find possible evidences. Evidences are found as metadata information on these drives. These metadata information are collected in a comma separated value-CSV format document. This CSV file can be imported to a database and can be easily analyzed. By the classical forensic investigator tools mostly can analyze only one media at a time, but by this way more than one digital evidence can be comparatively analyzed. Also, deleted files may hold evidences, so recovering of deleted files is an additional topic for this study. The structured codes and related documents have shared on github as an open project; to give a chance to extension of this study by new projects and we hope that the product of this study can be useful tool for computational forensic courses.

In this paper, we propose an anti-spoofing method that employs the fusion of various full-reference and no-reference image quality assessment techniques to detect fake and real ear images presented to biometrics systems under print attacks. In this context, full-reference image quality assessment measures such as Error Sensitivity Measures, Pixel Difference Measures, Correlation-Based Measures, Edge-Based Measures, Spectral Distance Measures, Gradient-Based Measures, Structural Similarity Measures and Information Theoretic Measures are used. Additionally, no-reference image quality assessment measures such as Distortion Specific Measures, Training Based Measures and Natural Scene Statistics Measures are implemented to distinguish fake and real ear images. A comparative analysis of the performance of these quality metrics and the proposed method using decision-level fusion of all aforementioned measures are performed. The experimental results are presented using AMI and UBEAR ear databases by creating print attack counterparts of the ear images used in these databases.

Image Enhancement is a required and indispensable technique in order to improve the image quality of digital images. Much as the digital cameras and mobile phones are available everywhere, lack of clearness on the side textures, emerging of dark or bright areas and creation of noise occurs due to reasons such as failure of camera foci, lack of lighting and atmospheric disturbances. As such, it is necessary and beneficial to develop an effective improvement algorithm in digital images addressing such negative issues and noises. The fundamental function of image improvement is to generate a new density value for each pixel value in the image through utilization of the transformation function after the density value of each pixel of introduction image is received. The proposed conversion function is named Regional Similarity Transfer Function (RSTF) in the study and the conversion is applied by taking into account the density distribution similarity between neighbor pixels. The intuitional optimization technique preferred mostly in engineering applications recently, named Gravitational Search Algorithm (GSA) has been utilized with an eye to optimize the parameter values of the proposed RSTF conversion function (1). An objective evaluation criterion was employed with a view to measure the quality of the images by finding the parameters of the conversion function with GSA. The objective function three performance measures-namely entropy value of images, sum of edge densities and number of edges- of which were combined, was preferred (2). Our experimental results reveal the fact that the proposed method efficiently eliminates the noises received from the images while increasing the image quality.

In this paper, one-shot-learning gesture recognition methods are reviewed and an approach of hand gesture recognition using one-shot-learning is proposed. This approach aims to recognize new categories of gestures from a single video clip of each gesture. The gestures are generally related to a particular task, for instance, hand signals used by divers, finger codes to represent numerals, etc. In this study, both RGB and depth images are utilized for a given dataset. A rich dataset, namely the ChaLearn Gesture Dataset (CGD2011), are employed. The dataset is divided into 20 different files which include 940 videos in total. Although training the system with only one example is difficult, depth and RGB images provide many new possibilities. We used the standard deviation of the depth images of a gesture and motion history image (MHI) method. Also, two dimensional fast fourier transform (2D FFT) is used to reduce the effect of camera shift. It is seen that FFT has no distinct effect on the image quality. Then, we compare image templates based on the correlation coefficients and Levenshtein, Mahalanobis, Frobenius distance measures. The Levenshtein distance measure is more suitable to match image templates compared to other distance measures. It is observed that MHI method gives better hand gesture recognition accuracy about one-shot-learning.

In software development processes, architectural documents can be prepared by the beginning of the project like Big Design Up front (BDUF) if software projects requirements are prepared with details and reviewed by the team. However, software projects with a lot of uncertainties or ambiguous requirements do not have any process to prepare and record architectural decisions during the software development. In recent years, agile software development has become very popular in the software industry. Therefore software development teams try to adopt their software processes against changing requirements and dynamic market conditions with using agile methodologies. Because of the underlying philosophy of agile, agile teams started paying more attention to working product over comprehensive documentation and big design up front. However agile software development also contains architectural and design decisions during the development. One of the agile principles also points that the best architectures, requirements, and designs emerge from the agile team during the development. Nevertheless, agile methodologies do not offer any processing cycle for architectural documentation in their process. In this article, we will propose how the architectural decisions will be documented in agile frameworks, which one is the most popular Scrum framework.

As is known, it is often difficult to store and transmit images used in various computer applications. A possible solution to this problem is to use one of the known data compression techniques because they help to reconstruct the image with a lower number of measurements. In this study, a new Singular Value Decomposition (SVD)based technique is proposed to compress images. The advantage of using SVD is that it both has energy compression capability and is easily adaptable to local statistical variations of the image. Furthermore, the SVD can be implemented with non-square, non-reversible matrices of size m x n. However, how to determine the threshold value for image compression in the SVD technique is still one of the fundamental problems. In this study, the desired threshold value is calculated by dividing the sum of the differences between the obtained singular values by the rank of the matrix. Simulation results confirm the feasibility of our proposed method.

Today, there are some difficulties of planning a social activity. One of the biggest challenges is that people have more mobile lifestyles in the last few decades. For this reason, the possibility of participating of people in a particular event varies according to the person’s current location. However, the fact that today's people are mobile as well as online, this makes it possible to reach them virtually even if they are not physically reachable. In this study, an approach has been developed to identify and recommend the most suitable candidates according to the compliance and location of the people for a social activity that is planned at a certain capacity. In the developed approach, people are weighted according to their compliance and physical distance to the event. Then, people are sorted by the location of the event. The most suitable people are identified, not more than the capacity of the event. The proposed approach uses person characteristics (gender, age, areas of interest), the Euclidean distance of the people to the event and the location where the event is to be done. The proposed approach also uses the Clarke & Wright Saving Algorithm, which is a heuristic algorithm and is mostly used in vehicle routing problems in the logistics area. Thus, the most appropriate persons can be identified that can be invited to an event with minimal cost. Furthermore, in addition to the use of this algorithm, if people invited to the event are taken by car, it is possible to determine the most suitable routes and to ensure that people are collected according to these routes and participate in the event.

Computer-aided curve and surface design models are used to design surfaces that do not have a particular shape. Since these surfaces cannot be expressed by known mathematical functions, curve and surface modeling methods such as Bezier, B-Spline and Non-Uniform Rational B-Spline (NURBS) have been developed. In this study, an application is developed that allows the NURBS curve algorithm, which is used as a method in 3D modeling, to be computed using Field Programmable Gate Array (FPGA) with parallel processing capability and displayed on the LCD touch screen. The B-Spline basis function which NURBS based on are sampled mathematically. The parametric values used in the display of the NURBS curves and surfaces are presented on the LCD with user interaction. Parametric values such as control points, knot vector, and weight vector are separately sampled for curves and mathematical solutions are given. The NURBS curve for user-defined control points can be displayed in real time on the screen. In addition, an implementation of the NURBS algorithm in the Visual Studio platform was developed and obtained results were compared.

In daily life we may encounter many different optimization problems. There are many different algorithms developed for solving these problems. The abundance of optimization problems in every field, such as science, engineering, economics, health, communication, production, etc., have made these algorithms are more popular. These algorithms are divided into two main groups as mathematical based and meta-heuristic based algorithms. The meta-heuristic algorithms are inspired by the nature events in general. In this study, we deal with the Vortex Search (VS) algorithm, which is one of the meta-heuristic algorithms. This algorithm is inspired from the vortex pattern produced by the vortical flow of stirred fluids. We proposed some improvements on vortex search algorithm to increase the performance of the original VS algorithm. To show the performance of Improved Vortex Search (ImpVS) algorithm, we used well-known meta-heuristic algorithms, such as Differential Evolution (DE) algorithm, Particle Swarm Optimization (PSO) algorithm, Artificial Bee Colony (ABC) algorithm, Simulated Annealing (SA) algorithm and original Vortex Search (VS) algorithm. The obtained Benchmark results show that the proposed ImpVS algorithm has got the competitive performance for the optimization problems.

Using Synthetic Aperture Radar images become popular in many military or civilian applications such as algorithm design, geo-referencing and Automatic Target Recognition. One of the main reason is SAR images can be obtained in any weather condition like rainy or cloudy weather even without daylight.However, Synthetic Aperture Radar (SAR) images contain multiplicative noise called speckle which makes analyzing images difficult. Therefore, there are many algorithms developed about despeckling SAR images in last decades. Each algorithm has strengths and weaknesses such as some algorithms work great in texture areas and some can work fine about homogeneous regions. To achieve more efficient result in despeckling SAR images, we proposed a method which uses 3 despeckling algorithms (SSD, MSAR_BM3D and FANS) and apply those algorithms in the regions which they are powerful. The proposed method splits a SAR image into smaller images and use Convolutional Neural Networks to categorize the sub images to find which algorithm is the best for that region. Afterwards, sub images despeckled using the algorithm which CNN selected and sub images come together and create the final despeckled image. The proposed method aimed despeckling of noises from the Synthetic Aperture Radar images more effective than the available despeckling algorithms.

Hiding and securing information is a basic demand throughout humanity. People have used their own bodies, languages, writings, etc. to provide this need. Steganography is acknowledged by science and art that researches hiding information methods. Steganography consists of two element basically that cover and secret information. In the past, people used their bodies and poems, diaries for cover and used tattoo and acrostic methods for secret information. In recently thanks to the developments of technology, Steganography has widened its methods and study areas. There are four Steganography methods which are text, image, audio and video in computer science. All types of Steganography methods have distinctive different ways to hide information. But if we want to mention the most used ones, we can say that changing characteristic of text (like color, font size) in text Steganography and changing Least Significant Bit(LSB) way for other types of Steganography methods. The LSB is a way that we overwrite the LSB of each byte of the cover (image, video, audio) with secret information binary representation. In our project, we are developing an android mobile application that allows user to hide a secret information inside any image. The image can be captured instantly or selected from user gallery. We are using LSB image Steganography method in order to hide secret information in image. Beside this, we encrypt the secret information with an encryption algorithm before inserting it in image. At the end, user can save the result image for the future or share with somebody who able to see the secret information only with this application.

This study proposes an information security risk assessment approach based on Bayesian networks and Fuzzy Inference System in order to evaluate and calculate both qualitative and/or quantitative risks. The proposed preliminary model is developed to analyse test processes for a software services company in order to evaluate the information security risks. In order to collect data for our risk assessment model, assets, vulnerabilities, threats, and related risk values are identified and analyzed with experts and managers based on the testing process in the company. Threats, vulnerabilities, risks, and their relations are constructed with a Bayesian network and marginal probabilities for each risk are calculated. Several fuzzy membership functions are designed for assets’ values, risks’ probabilities, and relative risk values. Fuzzy decision rules are constructed for some of the chosen risks by using the assets’ values, relevant risk probabilities, and relative risk values. In the final stage, the impacts of risk (loss) values are calculated by aggregation and defuzzification. Promising results have been obtained so far and this preliminary model will be used as a basis for an enhanced model, which can be successfully used for information security risk assessment and management with less subjectivity, more reliability, and more flexibility.

Osteoarthritis (OA) is the most common form of joint disease, and its impact is set to grow as the prevalence of obesity rises and our elderly population increases. As a result of this disease, it is necessary to make structural examinations for the determination of the deformations that occur. One of the methods used for structural analysis of biological samples is the wide-angle X-Ray scattering (WAXS) device. In this study, hip bone samples taken from humans during surgery were investigated using wide-angle X-ray scattering technique. Hip bone specimens were primarily compared based on regional density and later on based on sex. As a result of scatter patterns, the presence of crystal structures has been determined. The values of crystal structure obtained depending on low and high dense region and sex are different.As a result of gender related comparisons, it was found that crystal structures were better in males than females.

The finite element method (FEM) is a computational technique that is often used to solve biomedical engineering problems. The biphasic cartilage model plays important role in representing the mechanical behaviour of the articular cartilage . In order to obtain accurate results in finite element analysis of articular cartilage, it is necessary to determine appropriate FEM parameters such as mesh density and finite element type. Mode l s with small element sizes in the FEM allow more accurate re sul ts to be obtained however it requires longer calculation time. In contrast, large element size can lead to non-precision results while shortening the calculation time. The type of the elements may also change the results of FEM analysis for biomechanical problems. The purpose of this study is; to evaluate the effect of the mesh size and type of the finite element on the resul ts of the numerical biphasic tissues. In this study, in order to achieve thi s goal a series of compression analyzes were performed on the 3D biomedical models with different mesh density and element types using ABAQUS 6.13 software and the results were compared. The analysis results showed that mesh density element type and element type had little effect on the maximum reaction force . On the contrary, the mesh density had greatly increased the computational time.

Microsoft kinect sensor have been most of used camera among 3d vision systems. Microsoft kinect sensor can obtain depth images of a scene and 3d coordinates of human joints. Thus, anthropometric features can extractable easily. Anthropometric feature and 3d joint coordinate raw datas which captured from kinect sensor is unstable. The strongest reason for this, datas vary by distance between joints of individual and location of kinect sensor. Consequently, usage of this datas without kinect calibration and data optimization does not result in sufficient and healthy. In this study, proposed a novel method to calibrating kinect sensor and optimizing skeleton features. Results indicate that the proposed method is quite effective and worthy of further study in more general scenarios.

Filtering can be used for different purposes in image processing. One of them is to reduce noise in the image. In this study, local variance based on switching filter is designed to remove Gaussian noise from gray scale images. During filtering process, local variances of each pixel is calculated and then pixels are classified as five clusters according to their local variance values by the k-means clustering method. Depending on the result of the clustering, variance of the Gaussian filter kernel is tuned. In the smooth regions, in which variances of the pixels are low, higher standard deviation Gaussian filter is applied. Higher variance pixels represent the edge pixels, therefore lower standard deviation Gaussian kernel is applied to preserve the edges. In clusters with medium variance pixels, the standard deviation value in the Gaussian filter is changed depending on the local variance values. Experimental results show that designed local variance based switching filter gives better performance to remove the Gaussian noise at various levels compared to the classical filters.

In almost all areas of the life-cycle, measurement, contolling and even achieving in stable/desired values of temperature have big importance. The man-kind’s daily activities are influenced by various control systems in almost every direction. Also, control systems are widely used in all sectors of the industry. This study mainly focused on measuring and controlling the temperature values. The purpose is to keep stable the analog temperature data at the desired temperature by performing the necessary control procedures. In designed temperature control system, analog temperature values were measured by K type thermocouple. Since the temperature measured by the thermocouple is in the mV level, this data must be raised to 0-5 V to be supplied to the Arduino analog input (A0). The AD620 instrumentation amplifier was used for the upgrade. The digital output data from the Arduino PWM3 block is transmitted to the SSR (Solid State Relay) using the 74HC244 buffer. Temperature control was performed by the PID control software preparing in the LabVIEW program. In this study, temperature values are successfully obtained with a ±%1.5 accuracy via Labview.

Customer satisfaction plays an essential role in financial institutions. Particularly in the banking sector, a series of customer satisfaction studies is carried out in order to ensure the continuity of the customers with the bank. The most important ones of these are; questionnaires, feedback from the branch staff, and the increase in the client's banking transactions. By analyzing these studies, the satisfaction level of the customers can be measured. However, these measurements do not have a complete mathematical accuracy and can be misleading. In this study; the facial image of the customers who come to the bank are perceived by the camera and evaluated by emotional analysis. In this way, it is determined that the customer is satisfied or non-satisfied when leaving the bank. Problematic banking applications are also identified with the help of the analytical result of emotional analysis. In addition to this, the branch personnel of the bank who behave well to the customers are determined and performance evaluation is made more accurately.

A system is a set of interacting components are connectedin such a way that the vibration or response in the state of one component affects the state of others. A dynamic system is described by time differential equations; therefore, the future response of the system is determined by the present state of the system (the initial conditions) and the present input. Modeling and simulation are the prerequisite to the design of a dynamic system, as the designing and manufacturing a system and then testing it for expected performance would be unavoidably expensive. Wide spread availability of high speed and high storage capacity computers makes the simulation process even more attractive before the manufacturing stage for observing the expected performance of complex dynamic systems. However, before simulation phase of a system the mathematical model of the system must be prepared. For complex mechanical systems it is not always easy to establish the mathematical model. On the other hand, it is much easier to establish the mathematical model of an electrical system. Furthermore, simulation software is richer for electrical systems. For these reasons in this manuscript modeling of a complex mechanical systems will be realized using electrical circuit analog and then will be simulated as an electrical circuit. Advantages of this approach will be explored.

Power quality problems due to short circuit faults, are defined as changes in voltage, current, or frequency in the power system. Among the power quality problems in distributed generation systems are island mode operation, harmonics in current and voltage, voltage sags/swells, voltage interruptions and transients. The most common power quality problem in the distribution system is the voltage sags and swells caused by a short circuit fault. In this study, various Power quality problems due to short circuit faults such as line-to-ground, line-to-line and multistage faults are modeled in MATLAB/Simulink environment. In order to detect the voltage sag and swell problems, firstly the voltage sag that occurs in case of failure is examined and the response of the power system is observed. The study also models multi-stage failures as a result of failure to achieve relay synchronization. Examination of the voltage sags and swells clearly revealed the resulting waveforms, the response of the power system to the fault condition. Another advantage of the realized work is that the developed model can be used to measure the performance of the distributed generation system in failure diagnosis and classification studies.

Today, the use of meta-heuristic algorithms in solving non-linear and complex problems is becoming popular. These algorithms are inspired by natural selection, swarm intelligence, physical events and nature. Crab mating optimization algorithm is one of the meta-heuristic algorithms which was developed by V.R. Chifu in 2014. The crab mating optimization algorithm imitates the mating behavior of crabs in nature. One of the biggest shortcomings of this algorithm is that it has got the quite long running times for optimization problems. In this study, to increase the running speed of the original crab mating optimization algorithm, the mating process of the crabs in population was modified. A male crab mates with only a female crab in the new mating procedure. Therefore, the name of the proposed meta-heuristic algorithm comes from this new mating process as a Monogamous Crab (MC) mating algorithm. Vehicle routing problem (VRP) is the popular combinatorial optimization problem. VRP relates to the most appropriate route design to be delivered to a range of customer service by a number of fleets. In this study, the developed MC algorithm is adapted for the vehicle routing problem. The performance of MC algorithm was compared with those of metaheuristic algorithms. The results show that MC algorithm provides promising and competitive performance.

In this study, its multi-objective variant tree-seed algorithm, MOTSA, is proposed for solving multi-purpose optimization problems by motivating its performance on single-objective problems. In order to overcome selection issue in multi-objective problems, the well-known strategies, non-dominated sorting and crowding distance, of NSGA-II has been integrated with the proposed MOTSA. By doing this, the highest quality solutions from the combined populations of trees and seeds are selected and transferred to the next generation. The MOTSA are applied to solve well-known three multi-objective benchmark problems and obtained results show that MOTSA is an alternative multi-objective optimization algorithm.

Methods: In the provinces of Ankara, Adana and Mersin, 9 chemical working job security survey studies and work safety experts were carried out in this study. Computer software is developed by creating a fuzzy logic based risk assessment analysis model considering various hazards in occupational health and safety in the chemical industry. Results: It is very difficult to model risk in a workplace environment with many specific and ambiguous hazards and model a system to simulate these hazards. Software was developed by creating a fuzzy logic based risk assessment analysis model in consideration of many hazards in occupational health and safety in the chemical industry. An alternative approach to risk assessment has been proposed using fuzzy decision making approach and matrix method.

Wireless Sensor Networks (WSN) are used for the monitoring of objects in various fields of application as well as the monitoring of military and civilian environments. The energy consumption of sensors and the optimization of network lifetime in WSNs are among the important problems that are constantly investigated and for which solutions are developed by linear programming method. Furthermore, different algorithmic solutions have been developed to perform the dynamic deployment of the nodes efficiently for the solution of this problem. The proposed solutions require that the targets in the network are covered by a minimum number of sensors. k-coverage, that determines the degrees of coverage of the targets in the area of interest, is an important criterion in determining the number of sensors covering each target after the deployment of the sensors. Because the coverage of the targets by a minimum number of sensors and the minimization of the intersection area of the sensor increase the lifetime of the network by optimizing the energy consumptions of the sensors. In this study, the dynamic deployment approach based on the Whale Optimization Algorithm was proposed to provide the optimum solution to the k-coverage problem of WSNs by ensuring that the targets in the area are covered by a minimum number of sensors. This approach, that performs the effective dynamic deployment of sensors by covering the maximum number of target points and ensuring the minimum degree of k-coverage, was compared with the MADA-EM in the literature. Simulation results have shown that this approach is optimum and can be recommended in the solution of the k-coverage problem by ensuring that the targets are covered by a minimum number of nodes.

In this paper we present a cross-layer optimization method for adaptive video streaming in cellular networks. The proposed method makes use of a new scheduling algorithm, tailored to adaptive video streaming applications, which provides better allocation of radio resources in order to increase the video quality experienced by the users. After introducing our novel scheduling algorithm, we compare its performance with the stateof-the-art, using DASH as the adaptive video streaming technique and LTE as the cellular network technology. The results show that introducing DASH-awareness into the network increases the streamed video quality and the network utilization. We believe that the proposed novel cross-layer optimization method can also be applied to future cellular network technologies, such as 5G, where application-aware resource allocation will be crucial in supporting the required quality-of-service (QoS).

AntLion Optimization (ALO) algorithm is one recent of the meta-heuristic algorithms that was developed by Mirjalili in 2015. ALO algorithm imitates the antlion's hunting behaviour in its larvae phase. The long run time of ALO algorithm is the biggest disadvantage of this algorithm. To overcome this deficiency, we proposed some improvements on the mechanisms of the original ALO algorithm. In order to improve the ALO algorithm, firstly, the random walking distance was changed as twenty percent of maximum iteration instead of the maximum iteration number in the original ALO algorithm. We defined new movements between boundaries around the antlion on the phase of trapping antlion pits. In addition, the boundary checking process, the catching prey and rebuilding the pit were developed. The parallel machine scheduling problem (PMS) is defined that it is a set of independent jobs to be scheduled on a number of parallel machines. Scheduling process optimizes the production job sequences in terms of the different patterns. When there are the similar type of machines to be existing in multiple numbers, the jobs can be scheduled over these parallel machines at the same time. To show the performance of improved ALO (IALO) algorithm, some of well-known meta-heuristic algorithms were used in comparison works. The obtained PMS results show that the proposed IALO algorithm has very competitive results in terms of the mean, best, worst cost and standard deviation metrics.

In this paper, a particle swarm optimization (PSO) algorithm is introduced to determine learning parameters required for the backpropagation (BP) learning algorithm, which is used for training of a feed-forward neural network (FFNN). PSO algorithm utilized within the paper works slightly different compared to conventional PSO (CPSO) algorithm in such a way that each particle adjusts its position based on the best midposition of all particles and its group’s previous best. The major reason of such a change is to enhance the performance of CPSO algorithm, which is explained in detail in the study suggested by Tamer, S and et.al. To test the proposed method, a FFNN with three layers is designed for function interpolation. Learning parameters of the designed NN are determined by both conventional error and trial method and the proposed method. Afterwards, using these two groups of learning parameters, the NN is trained and tested under the same conditions. According to the test results, learning parameters determined by the PSO provide a better performance and interpolating capability for the NN than those determined by the conventional method.

The Galactic Swarm Optimization (GSO) is a novel method inspired by the movements of stars and star clusters. The GSO is a framework that uses the optimization methods known in the literature. GSO has a two-stage structure. In the first stage, the optimization method identifies possible good solutions by scanning the search space. In the second stage, the best solution is tried to be found by using possible good solutions. In the original GSO study, Particle Swarm Optimization (PSO) was used as an optimization method in both stage. In this study, Tree Seed Algorithm (TSA), a new optimization method in the literature, is used in GSO framework instead of PSO. In the experimental study, the performance of the GSO_TSA model has been investigated on numeric benchmark functions and obtained results are compared with GSO_PSO model.

Handwriting character recognition has been a popular problem among scientists for a few decades. United States Postal Service can be given as an example for a company that uses the recognition of digits in real life environment consistently. USPS uses digit recognition system to extract digits from pay checks and fastens the process of sending and receiving checks. Handwriting character recognition problem can be divided into two categories. Online character recognition and offline character recognition. A recognition pattern mainly based on angle of the strokes of stylus is called online recognition. A system is called offline when system takes images as inputs and tries to predict characters from given images by applying machine learning methods. We have worked on offline character recognition problem in this project. Many machine learning methods have been proposed over the years for solving this problem. In this paper we implemented 6 most popular machine learning methods to solve offline handwriting character recognition problem and compare the performance results to decide which method gives best accuracy results under pre-defined conditions. We have selected 92255 images from NIST Special 19 Database and used them as input images during the training phase of the selected machine learning methods. These methods are SVM, Decision Tree, Bag of Trees, Artificial Neural Networks (ANN), Deep learning network with autoencoders and Convolutional Neural Networks (CNN). We implemented all of these methods and compare the performance of the results according to accuracy metric. The results obtained from the comparison is going to help in deciding which ML method should be used to solve Offline Handwriting Character Recognition problem.

Over past two decades, many algorithms taking inspiration from natural phenomena have been proposed by the researchers. One of the famous algorithms is Artificial Bee Colony (ABC) algorithm which is inspired by the intelligent behaviors of the honey bees. Although original ABC algorithm has been proposed for solving continuous optimization problems, in order to effectively solve binary optimization problems original ABC should be modified. Using logic operator, genetic operator, and transfer function are the strategies to obtain binary solutions. Knapsack is a well-known binary optimization problem which aims to obtain a maximal knapsack packing. In this paper, various binary variants of ABC algorithm (xorABC, crossoverABC, vFunctionABC) are applied to 0–1 knapsack packing problem. The performance of three binary variants of ABC is investigated with respect to time and quality.

In the stand pipes, which are the only evacuation point of the raw gas released during the high temperature coking of the coal, the section reduction occurs due to the carbonization and the problem of degazing of the raw coke gas is experienced. This leads to an increase in the internal pressure of the raw gas in the furnace and emissions to the doors, which are the weakest points for sealing. It also leads to energy losses depending on the amount of leakage. The raw gas passing through the vertical chimneys is 900 degrees and it is isolated with fireclay bricks to protect the metal parts. In this improvement, high-alumina castable mortar is used instead of fireclay bricks. This has resulted in a reduction in emissions and maintenance costs.

RC4 is an algorithm that encrypts a data in the form of a bit string with a specified key. The security of RC4 with high encryption speed depends on the random key. Speed of image encryption is very important parameter due to size of the data. Performance analysis was examined using color image encryption, because RC4 is usually used in speed-critical applications. RC4 showed that the desired values could not be obtained when examining the histogram, correlation coefficient and information entropy analysis results. Because of this, chaotic systems are used to increase the performance criteria of image encryption with RC4. Chaotic systems are very sensitive due to their inherent dependence on the initial conditions and dynamic variables. Not random and non-periodic oscillations these systems are performed in a certain frequency range. The RC4 algorithm are enhanced by using chaotic system-based encryption algorithms because of its key size capability and speed. Performance criteria have been improved using 2D Cat Map, Tent Map and Lorenz chaotic systems. When we examine only the encryption made with RC4 and the encryption made with RC4 supported with chaotic systems; more successful results are obtained from histogram, correlation coefficient and knowledge entropy analysis. In addition, the structure of chaotic systems is increased key sensitivity and key size and thus a more secure algorithm is obtained.

The global problem of the growing city centres has many causes and requiring many different solutions. Existing urban infrastructures are having difficulty to meet the needs within the increasing population and urbanization of the cities. In this context, innovations must be made in many areas of the infrastructure of the cities such as Transport, Energy and Environment cleanliness. The most important increase due to the population growth in urban areas occurs in the traffic intensity. The number of vehicles increasing in traffic brings with it many new problems such as energy, time, and environmental pollution. Several field studies have been done so far to reduce and minimize traffic intensity. In this context, different solutions have been tried, such as speed controls, camera systems equipped with image processing techniques, and measures to reduce the intensity of intersection connections. As a result of interviews and determinations within the scope of this study, it is seen that traffic lights have a serious effect on traffic regulation. In this study, the working principle of traffic lights was first investigated. In particular, the optimization and the techniques of signaling times of traffic lights have been examined. Traffic lights, which usually operate for a fixed period of time, can cause the vehicles to remain in traffic for a longer time and increase traffic intensity. Systems that operate according to the vehicle density cause very important improvements if they are operated through the appropriate mathematical model. In our work, queuing theory is mentioned, the application areas of theory are investigated and the data obtained from the field have been tested through this model. According to the queuing theory, the intensity of the intersection arms, the performance of the lights, arrival and the service ratios were obtained. With this study, it is aimed to bring a new approach to the density at the intersection of the city centers.

Today, approximately 200 million people around the world are required to regularly check blood sugar levels every day, and this number is increasing day by day. If hyperglycaemia and hypoglycemia occur as a result of blood sugar level abnormalities, serious tissue and organ damage and, most importantly, vital risks can occur. In generally, blood glucose level measurement methods are divided into three categories, which are invasive, minimally invasive and non-invasive. In invasive methods people need to measure blood glucose levels by drilling their fingers, squeezing blood droplets on test strips and treating the results with portable glucometers. The process can be uncomfortable and complicated and has to be repeated many times each day. By using minimally invasive methods, the glucose ratio is determined by the help of tissue fluid or very little blood. Actually this method is uncomfortable for human life too. For this reason, there is a growing need for a new generation of non-invasive glucose-level monitoring systems in which the glucose level can be reliably determined. The goal of the ongoing works in literature are to prevent or delay early diagnosis and complications, rather than to treat the diabetes. This review giving a comprehensive knowledge about non-invasive design methods used in the literature.General definitions are given for each of the design methods. Scientists, laboratories and universities have been working on the design of non-invasive glucometer with various methods, yet there is no product that can measure with high accuracy.

Path planning problem plays an important role in mobile robot works. The robotic systems use intelligence algorithms to plan the path of the robot from one point to the other point. The main goal of path planning is to find the allowable movements of a robot in an environment with obstacles. These motions involve a path free of collision from the start position to the target position. In this study, Gray Wolf Optimization (GWO) algorithm was adapted to solve robot path planning problem. GWO algorithm imitates the hunting behavior and social leadership of gray wolves in nature. The leadership hierarchy consists of four grey wolf groups: alpha, beta, delta, and omega wolves. This algorithm comprises hunting mechanism with three stages: searching for prey, encircling prey, and attacking prey. In the test simulations of the robot path planning, we used a map with three circular obstacles. GWO algorithm was adapted to this problem. While finding the candidate solutions in path planning, three coordinate points are used between start and target points. For each iteration, these coordinate points are updated by GWO algorithm. If the solution point is in the obstacle zone, then violation is added to the cost function. The performance of GWO algorithm was evaluated with those of meta-heuristic algorithms for solving the robot path planning problem. The results obtained by GWO algorithm show that the optimal path is found for used test map.

Detection of the breast cancer at the early stage has gained much attention over last decades. In this paper, a simulation study of a radar-based ultra-wideband microwave system is presented to detect breast cancer tumors. The main principle of this technique is based on the significant difference in the dielectric properties of malignant breast tumors and normal breast tissue in the microwave frequencies. The tumor’s electrical properties, in particular conduction and specific absorption rate (SAR), change significantly from those of healthy biological tissue when exposed to microwave radiation. In the measurements, a simple planar breast phantom that consisted low dielectric constant material to represent the fat tissue and high dielectric constant material to represent the tumor is used.

Over the last decade, agile practices become very popular amongst software development. According to one of the phrases of the Agile Manifesto “Working software over comprehensive documentation” sometimes could lead practitioners to the misunderstanding of “documentation is not valuable” or “not needed at all”. Because of this understanding from software community, agile practitioners do not give enough attention to architectural related documents. However, documentation is also a communication way between people and this communication should be also simple and lean considering agile principles. Commonly used traditional architectural documentation is very comprehensive and detailed. Creation and maintenance of this architectural documentation take too much effort for agile teams. Therefore, existing architectural template documents cannot serve agile teams in the best way. Rather than using existing architectural documents, this article presents a new lightweight architectural documentation template that can be used maintained easily in agile projects.

Building effective schedules in academical institutions considering the wishes and needs of administrative staff, professors and students at the same time is a rather difficult and time-consuming activity for staff involved in this work. Despite improvements in software and hardware technology in recent years, charts are still manually created in many educational institutions and the desired efficiency has not achieved. In this study, the course chart of Mersin University Engineering Faculty was built using Ant Colony Optimization (ACO) technique. While the course schedule was being formed, 9 departments, 24 common classrooms, 105 faculty members, 239 courses, 14.374 students who have attendance obligations and 8286 students who have not attendance obligations were taken into consideration. In the placement of the courses, adaptation to ACO algorithm has been achieved by targeting the maximum lecture minimum classroom usage. The appropriate hours of the lecturers were accepted as strict constraints and other cases were added to soft constraints. All courses of Mersin University Engineering Faculty have placed the course schedule to appropriate classrooms at the rate of 99% using ACO technique, and 17 classrooms of common 24 classrooms were determined to be sufficient for educational activities.

Image segmentation is one of the most tedious and challenging research of image processing field and defined as the partitioning of a given image to a finite number of nonoverlapping regions such that every homogenous region is connected through a sharp line. When segmenting an image, each pixel is assigned a label so that similar labelled pixels have certain visual characteristics. Image segmentation is a popular image processing task for image interpretation and analysis. Especially, the scope of medical image segmentation includes a wide spectrum of subjects including locating tumors, measuring tissue volumes, planning the treatment, enhancing the medical images, diagnosis, image retrieval etc. For image segmentation and/or other image processes, various color spaces are used: RGB, CMYK, HSI and YIQ. Each color space was proposed for specific purposes and each of them has certain advantages over the others. Color image segmentation provides the user much more information comparing to grayscale image segmentation. This paper performs different medical image segmentations using CIE L*a*b color space. Images are converted to L*a*b color space and color difference idea is used to segment the user selected regions. This paper also covers commonly used color models such as RGB, CMYK, HSI and YIQ.

The using and importance of web services that flexibly meet the need for communication regardless of parameters such as platform, operating system are increasing day by day. In a simple sense, Web services carry a lot of data because they provide communication. With the increasing usage of web services and evolving technology, various methods have been developed to conceal data, to provide security and to prevent access by third parties in web services. At the same time, attack and injection methods for web service servers or web services have been developed. Some of these methods exploit the fact that the web services are XML-based. For example, XML injection, XPath (which stands for XML path language) injection are some of them. However, perhaps the most common type of attack are DOS and XDOS attacks. The purpose of this study is to gather the reasons of web service attacks, the precautions to be taken against the attack, the solutions for the exploits.

The Salp Swarm Algorithm (SSA) is one of the recently proposed nature-inspired metaheuristic algorithms. SSA mimics the life cycle of salp swarms. Salp swarm is an animal group which lived in oceans. The navigating and foraging behaviors are the characteristic properties of the salp swarms. These behaviors are modeled as an optimization algorithmin SSA and it is firstly proposed for solving continuous optimization problems. In literature, there is no binary version of this algorithm which uses transfer functions. In this work, SSA is modified for solving binary optimization problems by using transfer functions. Transfer functions are used to convert the continuous decision variables to the binary decision variables. With this modification, the structure of SSA has not been changed, but only the Sigmoid and the Tangent Hyperbolic transfer functions are adapted. In order to validate the performance of the proposed binary SSA, a well-known pure binary optimization problem, uncapacitated facility location problems (UFLP), set is considered. UFLPs are used for a benchmarking of many metaheuristic algorithms such as; artificial bee colony, tree-seed algorithm, particle swarm optimization, differential evolution and artificial algae algorithm. The experimental results of 12 UFLPs are compared with each other and state-of-art algorithms. Experimental results demonstrate that the SSA is a promising solver for lower dimensional problems, but its performance should be improved on higher dimensional problems.

In this study, specific absorption rate (SAR) simulations of rat model have been carried out by using a finite integration technique (FIT). Although FIT is similar with finite difference time domain (FDTD) method in most ways, an integral form of Maxwell’s equations are used in the FIT method. A monopole antenna working at 900 MHz has been designed for the electromagnetic source. Conductivity and permittivity of tissue have been selected from realistic values and implemented for the voxel based rat model. Simulations have been implemented with the 5 W stimulation power. Aforementioned antenna has been located at 3.5 cm and 5 cm away from the nearest point of the rat model, respectively. Total SAR values are found as 0.483 W/kg for the 3.5 cm distance and 0.315 W/kg for the 5 cm distance. Maximum SAR induced at a head region as it is expected. Furthermore, cross section of the head and body results indicate that induced SAR vary in different parts of a body because of electrical properties of each tissue. As the distance of the antenna increases, the SAR value decreases. Results show that average SAR value in 1 gr rat tissue is higher than the value in 10 gr rat tissue.

A well balanced dataset is crucial for the performance of the data mining classification algorithms. In medical datasets, the percentage of normal labeled classes is higher than the percentage of abnormal labeled ones, which is called as class imbalance problem in data mining. If training dataset is imbalanced, the classification algorithm generally predicts the labels of the majority class instances correctly and the minority class instances incorrectly which leads to a major problem for artificial intelligence based medical diagnosis systems. To overcome this problem, many researchers proposed over-sampling and under-sampling techniques in the literature. Over-sampling techniques increase the number of minority class instances, where the randomly chosen instances from minority class is duplicated and added to the new training dataset or synthetic instances are generated from the minority class. Under-sampling techniques decrease the number of majority class, where the randomly chosen subset of majority class is combined with the minority class instances as the new training dataset. In this study, the effect of over-sampling and under-sampling techniques in medical datasets is examined. For the experimental study, several medical benchmark datasets and well-known classification algorithms are used.

There are many qualitative and quantitative decision-making criteria in supplier selection (e.g., cost, quality, service or lead time). The today’s business environment requires choosing the right supplier with the environmental concerns in addition to the well-known selection criteria. We claim that a supplier selection accounting for the environmental concerns increases the supply chain responsibility, e.g. customer satisfaction, cost reduction and a clean environment. Therefore, we introduce a multi-criteria decision-making problem accounting for the environmental and social indicators that might be used to select the supplier of a wood glue which does not contain environmentally hazardous substances. A real-life case encountered in the furniture industry, is analysed with an expert choice software using the analytic hierarchy process decision making methodology.

Nowadays everyone is trying to record the moment everywhere and wants it to be perfect. Beyond resolution, there is a desire to get steady shots regardless of the environmental conditions. The gimbal stabilization system ensures a stable image by blocking motion-related vibrations before they are transferred to the camera lens axes. Thanks to the Three Axis Gimbal, perfect images can be achieved by minimizing the vibrations while jogging, climbing or coming down stairs, cycling, or using any kind of vehicle. In short, a three-axis gimbal can be integrated everywhere a fixed image is needed. It is envisaged that gimbal stabilization system will be needed in many scientific studies in the following periods. The aim of this study is to present the Three Axis Gimbal mechanism. Three separate brushless servo motors are installed on each axis for absorbing unwanted movements. The gimbal is also equipped with an inertial measurement unit consisting of a gyroscope and accelerometer close to the camera mount point. The general control system and PID controller are simulated by using MATLAB and the results are shown graphically.

Quadratic Assignment Problem (QAP) is based the facilities allocation, and it is a difficult combinatorial optimization problem. The objective of this problem is to make total assignment cost minimum while being assigned facilities to locations that are already known. To solve this problem, the different methods are used in the literature. Meta-heuristic algorithms are ones from these methods and in this study, we present a new version of recent antlion optimization algorithm for QAP. AntLion Optimization (ALO) algorithm was developed by Mirjalili in 2015. ALO algorithm is based on the hunting behaviour of the antlion. This algorithm comprises five stages: random walking mechanism, constructing trap, trapping in the antlion’s pit, sliding ants in the pit, catching the prey and reconstructing the pit. Although ALO algorithm is successful in benchmark functions of multi dimensions, it has got some drawbacks. The most notable improvement is the use of tournament method instead of roulette wheel method. In ALO algorithm, the antlion is chosen from the population by roulette wheel method for using in each ant's random walking model. The roulette wheel method is more successful in maximization problems. In the minimization problems, the tournament selection method is more efficient method than the other selection methods Therefore, we used the tournament selection method in this study instead of the roulette wheel method on random walking mechanism. This proposed algorithm has been called the tournament selection based antlion optimization algorithm (TALO). To evaluate the performance of TALO algorithm, we used well-known meta-heuristic algorithms. The results provide the proposed TALO algorithm has the best performance in comparison with those of the other algorithms.

Keeping the quality goals in software is not a matter of chance. It needs proper planning and continuous attention of the development team. The main responsible for achieving the quality goals is the software architect. The architect needs to contribute in: clarifying and defining the goals, make a design that maps the required quality. However, that’s not enough. The architect needs to govern all development and test activities to move towards the goals in harmony as a team. In the end, software quality depends on the design decisions, implementation and the also definition of the goals itself. A process for tracking the architectural quality is presented in this paper with an analogy to the development processes: “V Model” and “W Model”.

In this study, the Opposition based learning Spiral Optimization Algorithm (OBLSOA) is presented for training Multi-Layer Perceptron (MLP). The main idea of Spiral Optimization Algorithm (SOA) is based on the dynamic step dimension in its spiral path trajectory. The primary opposition based learning (OBL) concept first was come from the Yin-Yang symbol in the ancient Chinese philosophy. According to OBL concept, if a candidate point is far from the solution, the opposite point of this candidate can be closer to the solution than that point. We applied OBL concept to spiral optimization algorithm for training MLP. OBLSOA comprises two main stages: the first is the opposition-based learning population initialization and the other is opposition-based learning generation jumping. To evaluate the performance of the proposed OBLSOA, we used eight standard datasets including four classification datasets (XOR, balloon, Iris, breast cancer) and three function-approximation datasets (sigmoid, cosine, and sine). The performance proposed OBLSOA was compared with the original SOA for all datasets in terms of the Mean Square Error (MSE) metric. The training and test results show that the proposed OBLSOA is able to be provide very competitive and effective in training MLPs.

Network coding has emerged as a paradigm for communication systems in which each intermediate node in the network generates and transmits output data by encoding previously received packets in a manner to increase the bandwidth efficiency of the system. The multiple access relay channel (MARC) is one of the real-world reference network coded communication scenarios where multiple users transmit data to a common destination through the use of one or multiple relays. In this paper, performance of demodulate and forward protocol which is among the prominent digital relaying techniques is considered in MARC systems. A convolutional code is used as the channel code. Maximum likelihood (ML) detection and user selective relaying are utilized in order to decrease the performance degradation due to decision errors at the relay. The simulation results obtained for Rayleigh fading channels have shown that the examined joint channel-network coding approach is superior with respect to non-cooperative system by providing full diversity gain.

The main objective of this study is to automatically extract tea gardens from large geographic areas using high-resolution digital orthophoto maps. To achieve this objective, object-based image analysis and decision tree (DT) classifier were integrated. For segmentation, multi-resolution image segmentation algorithm was used which is implemented in Definiens Developer commercial software. Both scale and compactness parameters were empirically calculated that produced optimal results. The segmented objects were selected manually for training the DT classifier from all used images. Spectral and textural features were extracted from each segment and to make the features robust against local variations, they were extracted at two image scales and final feature vector was formed by averaging the two feature vectors. The selected optimal features were used to train the DT classifier and then applied it on the test data to generate thematic maps for tea gardens. The performance of the proposed method was evaluated by comparing results with the reference data that produced promising results for mapping tea gardens (overall accuracy 88%) on our dataset.

Target detection and tracking in video data is a complex problem. Especially for designing and developing surface to air tracking systems should be dealt with this problem strictly. In this study a combination of an image processing technique and Probabilistic Multi-Hypothesis Tracker (PMHT) is used. The target is discriminated from the video data for target initiation. In the subsequent steps the same discrimination method is used to obtain proper data for track continuation. For target identification from video data a transformation is used and target based pixels are discriminated from the background. Then image is transformed into point measurement data with amplitude information. Thus, video data is made suitable for tracking with PMHT. The resulting algorithm performs target detection and tracking operations automatically.

In terms of quantity, around 8 billion of sensors are connected to IoT systems by 2017. These sensors may be utilized in many ways, such as emergency reporting and data collecting. IoT mesh networks function not only in normal conditions, even in emergency situations such as climate disasters, fire, flood, earthquake, tsunami, war or terrorism-related nuclear, biological or chemical attacks or conventional attacks. Such circumstances cause mass panic and chaos resulting in serious consequences unless contained and controlled. In this study, we propose a conceptual design of a functioning prototype which has the operational ability to provide an auxiliary network connection, as well as detecting Internet of Things devices in the area of disaster, collecting IoT device info and providing a mobile WAN access to the user.

In this study, we intended to recommend possible books to be checked out from Seattle Public Library (SPL) within a month. While it seems possible to make daily estimates from existing data, it will be more useful to make monthly data forecasts since SPL provides fresh data every month. The information obtained here will contribute to logistic modelling. Since some assumptions on the location of the books and storage capacity of each location are required for the better management of the resources, this problem can be considered as a warehouse resource allocation problem. In order to perform the required predictions, Naïve Bayes (NB) algorithm is applied on the Seattle Public Library Dataset (SPLD), which contains all of the checkout records between 2005 and 2017 in the SPL.

In production systems, one of the main part routing problems is the determining the best process sequence and the best machine-operation pairing. In real world systems, flexibility is important to provide alternative part routings. The system is considered flexible when certain operation of a part can be processed on more than one machine. However, flexibility increases the complexity of system. This paper deals with assignment of operations to a machine and determining the best process plan for each part under flexible environment. We used a harmony search algorithm to cope with highly complex and nonlinear problem in which makespan is considered as the objective function and evaluated by using a simulation model.

Underwater sensor networks (UWSNs) are composed of a certain amount of sensors and/or vehicles that interactively glean data from underwater environment and cooperatively perform predetermined tasks. Each of these battery-limited sensors dissipates a considerable amount of energy during sensing, communicating and data processing activities, where replenishing the drained batteries is impractical and time consuming, and interrupts the ongoing communication. Therefore, energy conservation and routing strategies are vitally important for accomplishing a certain task for a particular underwater application. In this paper, we review the recent advances in UWSNs, including their applications and joint routing optimization and energy conservation techniques. Finally, several appealing directions for future research on UWSNs are presented.

Faced with the growing demand for quality products in markets and industries in agricultural sectors . from consumers, sellers, and producers. The research aims to respond to this, by using effective and efficient technologies, namely image processing and computer vision, to automate the process of inspection and evaluation of the quality of agricultural products. Conducted for many years by human experts. The use of these technologies concerns both the detection of fruit diseases and their classification. To follow this concept, we chose to focus our work on fruits classification. whose purpose is to separate infected fruits from those that are not affected. However, based on the concepts of computer vision, the proposed technique is centered on three steps. The first step concerns preprocessing and segmentation, in which, we resize and improve the quality of the images. The second step involves, deep pretrained models (Alex-Net), these are used for the extraction of the features in the different fruits (banana, apples, oranges). And finally, we performed the classification, by using multi-class SVM. The studies were conducted on the public dataset, the Kaggle dataset, to obtain a 99.50% classification accuracy and on a new dataset for a accuracy of 85.7%. The results clearly show that the proposed method works well in terms of improvement in classification accuracy and precision.

Automated recognition and classification of bacteria species from microscopic images have significant importance in clinical microbiology. Bacteria classification is usually carried out manually by biologists using different shapes and morphologic characteristics of bacteria species. The manual taxonomy of bacteria types from microscopy images is time-consuming and a challenging task for even experienced biologists. In this study, an automated deep learning based classification approach has been proposed to classify bacterial images into different categories. The ResNet-50 pre-trained CNN architecture has been used to classify digital bacteria images into 33 categories. The transfer learning technique was employed to accelerate the training process of the network and improve the classification performance of the network. The proposed method achieved an average classification accuracy of 99.2%. The experimental results demonstrate that the proposed technique surpasses state-of-the-art methods in the literature and can be used for any type of bacteria classification tasks.
