In this study, heat treatment was applied for four 1040 quality steels and then cooling process was performed
in different conditions. One of the specimens was cooled in furnace and the other specimens were cooled in
air, oil and water respectively to determine the effect of cooling conditions on fracture toughness. Fracture
and precrack surfaces were examined by Nikon Shuttlepix Digital microscope during analysis and Scanning
Electron Microscope(SEM) after fracture toughness measurement. Results show that, cooling conditions
significantly effect the fracture toughness value of specimens.

This paper inspects the deforestation of Trabzon in Turkey, due to urbanization, between 2006 and 2016. For this purpose, Landsat 7 ETM+ (Enhanced Thematic Mapper Plus) images are obtained from United States Geographical Survey (USGS) archive (USGS, 2017a) and their VNIR bands related to this study are utilized. For both years, and for each band, histograms are equalized. Finally, Normalized Difference Vegetation Index (NDVI) values are calculated as images. Resulting vegetation indexes are assessed in comparison to the binary ground truth images. A visual inspection is also done with respect to Google’s Timelapse images for each year to validate and support the results.
