Concentrations of environmental radioactivity in sediment cores from kulakcayiri lake
(Turkish Chemical Society, 2018)
This paper is about measurements of environmental radioactivity in samples taken from a lake bed and from different depths. The study is based on gamma spectrometric analysis of some radioisotopes encountered in sediment ...
Modeling and analysis of dielectric materials by using gradient-descent optimization method
(World Scientific Publ Co Pte Ltd, 2017)
This study presents a numerical method based on parallel RC equivalent circuit model fitting methodology for analysis and modeling of dielectric materials. The proposed method employs gradient-descent optimization method ...
An aridity index defined by precipitation and specific humidity
(Elsevier, 2012)
The United Nations Environmental Programme (UNEP), defined an aridity index (AI) by the ratio of the annual precipitation and potential evapotranspiration (PET) totals. In this work, specific humidity was used instead of ...
The sub-climate regions and the sub-precipitation regime regions in Turkey
(Elsevier, 2012)
A matrix created from the correlation coefficients of the meteorological data was used as input for cluster analysis and this application yielded much better results in high cluster solutions as compared to classical ...
Contemporary surface wind climatology of Turkey
(Springer Wien, 2013)
The aim of this study was to examine the climatological characteristics of boundary layer gradient winds in Turkey in detail. In the study, monthly average wind speed (V (m)) data measured at 267 stations for the 16 ...
Periodic Structures of Great Lakes Levels Using Wavelet Analysis
(Sciendo, 2011)
The recently advanced approach of wavelet transforms is applied to the analysis of lake levels. The aim of this study is to investigate the variability of lake levels in four lakes in the Great Lakes region where the method ...
Overall cost optimization of prestressed concrete bridge using genetic algorithm
(Korean Society Of Civil Engineers-Ksce, 2013)
Overall cost optimization of Prestressed Concrete (PC) bridges is investigated in this study. The purpose of this study is to determine the optimum span number and optimum cross-sectional properties of multi-span bridges. ...
Recycling of Coal Ash as A Building Material Via A Stabilization/Solidification Method
(Global Network Environmental Science & Technology, 2013)
This study examines stabilization/solidification (S/S) techniques for coal ash/cement systems that involve the production of construction products while minimizing contamination and recycling the coal ash (CA). In these ...
Tracks of Foreign Architects of the Early Republic Period in Turkey, Franz Hillinger Sample
(Yildiz Technical Univ, Fac Architecture, 2018)
In 30's, the conceptual debates on Modern Architecture in Turkey gained a new dimension by the arrival of german speaking and German avant-garde architects and urban planners. These architects and urban planners have tried ...
Optimization of durability properties of concrete containing fly ash using Taguchi's approach and Anova analysis
(Pontificia Univ Catolica Chile, Escuela Construccion Civil, 2018)
In this study, optimization of durability properties of the concretes was performed by using Taguchi method and Anova analysis. The durability performance of the concretes was evaluated using measurements of rapid chloride ...
