Traditional wooden buildings and their damages during earthquakes in Turkey
(Pergamon-Elsevier Science Ltd, 2006)Wood is one of the oldest structural materials used in structures in many parts of the World. Woodframe buildings were also commonly constructed in Turkey until approximately 1960. After that, as reinforced concrete and ... -
OBJECT BASED CLASSIFICATION OF UNMANNED AERIAL VEHICLE (UAV) IMAGERY FOR FOREST FIRES MONITORING
(Parlar Scientific Publications (P S P), 2019)In case of fire, determination of burned trees and fire direction is very important. Until now, satellite images and aerial photographs have been widely used in forest fire studies. However, these data can be ineffective ... -
The in situ natural radionuclide (U-238,Th-232 and(40)K) concentrations in Gumuhane granitoids: implications for radiological hazard levels of Gumuhane city, northeast Turkey
(Springer, 2019)We have carried out 48 in situ measurements on radioactivities of U-238, Th-232 and K-40 isotopes at the Gumuhane granitoid plutons employing gamma-ray spectrometer with a NaI(Tl) scintillation detector. The radionuclide ... -
Distinct contamination indices for evaluating potentially toxic element levels in stream sediments: a case study of the Harsit Stream (NE Turkey)
(Springer Heidelberg, 2020)This paper revealed that the level of certain potentially toxic elements (PTEs) can be reflected in stream and terrace sediments from Harsit Stream in Northeast Turkey. The potential toxicity of these elements was established ... -
Trace and rare earth elements as indicators of provenance and depositional environments of Lias cherts in Gumushane, NE Turkey
(Elsevier Gmbh, Urban & Fischer Verlag, 2012)Trace elements and rare earth elements (REEs) of Lias-aged cherts in the Gumushane area were studied in order to understand their origin and depositional environment. Twenty three chert samples from five stratigraphic ... -
Genetic characterization of the Akkaraman, Morkaraman and Karayaka sheep through microsatellite variation
(Agricultural Research Communication Centre, 2015)Genotypes have to be controlled periodically and necessary-precautions should be taken in order to ensure that animal biodiversity is not lost. In this study, the genotypes of the Akkaraman, Karayaka and Morkaraman species ... -
Evaluation of potentially toxic element contents and Pb isotopic compositions in Ankara Stream sediments within an urban catchment in central Turkey
(Springer, 2017)This study aimed to interpret the spatial distribution, enrichment factor (EF), and geo-accumulation of potentially toxic elements in the bed sediments (ASBS) and Pleistocene-aged overbank sediments (ASOS) of the Ankara ... -
Geothermal energy: Power for a sustainable future
(Taylor & Francis Inc, 2002)This paper discusses the potential and utilization of geothermal energy in Turkey. Geothermal energy for electricity generation has been produced commercially since 1913, and for 4 decades on the scale of hundreds of MW ... -
A reduced variance unsupervised ensemble learning algorithm based on modern portfolio theory
(Pergamon-Elsevier Science Ltd, 2021)Unsupervised ensemble learning or consensus clustering has gained popularity due to its ability to combine multiple clustering solutions into a single solution that is robust and often performs better than the individual ... -
Estimating the number of clusters in a dataset via consensus clustering
(Pergamon-Elsevier Science Ltd, 2019)In unsupervised learning, the problem of finding the appropriate number of clusters-usually notated as k- is very challenging. Its importance lies in the fact that k is a vital hyperparameter for the most clustering ... -
The Effect of Grain Growth Temperature on the Trapped Magnetic Field of Y358 Superconductors
(Springer, 2021)In this study, three different Y358 samples were produced by the melt-powder-melt-growth (MPMG) method at different maximum grain growth temperatures of 1030 degrees C, 1040 degrees C, and 1050 degrees C. The differential ... -
Mineralogy, petrography and whole-rock geochemistry of the Tertiary granitic intrusions in the Eastern Pontides, Turkey
(Pergamon-Elsevier Science Ltd, 2006)Granitic intrusions in Eocene and post-Eocene volcanic rocks outcrop in the Northern and Southern Zones of the Eastern Pontides. NE Turkey. Intrusions in the Northern Zone extend NW-SE whereas those in the Southern Zone ... -
Geochemical and isotopic characteristics of stream and terrace sediments of the Harsit Stream, NE Turkey
(Geological Soc Publ House, 2017)The current study compares and contrasts the elemental concentrations and the Nd, Sr and O isotopic compositions of sediments collected from the Harsit Stream bed sediments (HSBS) and terrace sediments (HSTS). There are ... -
Tracing provenance and chemical weathering changes in Ankara Stream sediments, central Turkey: Geochemical and Sr-Nd-Pb-O isotopic evidence
(Pergamon-Elsevier Science Ltd, 2018)This study aims to analyze the changes in sediment provenance through the geochemical and Sr-Nd-Pb -O isotopic composition of the Ankara Stream bed and overbank sediments (ASBS and ASOS) and to examine the weathering and ... -
