Symbiotic Organisms Search Algorithm for multilevel thresholding of images
(Pergamon-Elsevier Science Ltd, 2020)Thresholding is a frequently used method in image processing because of its consistency and low computational cost. Otsu's and Kapur's methods are two important techniques that were proved to be best thresholding methods. ... -
Assessment of the concentration and environmental impacts of potential hazardous elements in coalfields in Northeastern Turkey
(Springer, 2021)To investigate the impact of potential hazardous element (PHE) contamination on environmental and human health, the coaly shale, coal and shale coal outcrops of four sites, namely Ozyurt, Tarhanas, Kayadibi (Gumuhane), and ... -
Aflatoxin levels in raw and processed hazelnuts in Turkey
(Taylor & Francis Ltd, 2012)Aflatoxin levels in hazelnut samples obtained from exporter companies were monitored over a 3-year period. A total of 3188 samples of raw and processed hazelnuts were analysed using an HPLC method. The total aflatoxin ... -
A comparison of alternative curve fitting techniques for different earthquake fault parameters of Iranian earthquakes
(Univ Nacional De Colombia, 2020)In this study, we tried to estimate the optimum linear equations among the parameters associated with different earthquake fault mechanisms for Iranian earthquakes. For this purpose, we tested different curve fitting methods ... -
Power Spectrum Analysis of EEG for Watching 2D & 3D Videos and Resting State
(IEEE, 2018)Analysis of the brain waves has become useful over than 80 years. Along with the medical application, the brain signal is also used for other research works in the last fifteen years. In this study, by considering the depth ... -
Crustal Contamination of Tertiary Volcanic Rocks: Evidence from K, U, Th and Radiogenic Heat Production Data in Eastern Pontides (NE Turkey)
(Springer Basel Ag, 2021)Herein, we present new U-238, Th-232, and K-40 radionuclide concentrations, density and radiogenic heat production (RHP) data on the Tertiary volcanic rocks outcropping in Borcka, Gumushane and Trabzon regions within the ... -
U-Pb zircon ages and petrogenesis of the Late Cretaceous I-type granitoids in arc setting, Eastern Pontides, NE Turkey
(Pergamon-Elsevier Science Ltd, 2021)The Eastern Pontides Orogenic Belt (EPOB) as a well-preserved ancient magmatic arc situated in the eastern part of the Sakarya Zone and has key importance to allow for proper reconstruction of the geodynamic evolution of ... -
Complementary and alternative treatment methods for menopausal hot flashes used in Turkey
