Boudiaf, Besma; Şen, Zekai; Boutaghane, Hamouda (Springer Science and Business Media Deutschland GmbH, 2021)Climate change impacts affect the hydrological cycle and hence the availability of water resources and their management. Rainfall, the most important hydro-meteorological event and as the main source of water, may have ... -
Climate change impacts on sea surface temperature (SST) trend around Turkey seashores
Dabanlı, İsmail; Şişman, Eyüp; Güçlü, Yavuz Selim; Birpınar, Mehmet Emin; Şen, Zekai (Springer International Publishing AG, 2021)This paper focuses on sea surface temperature (SST) trends due to the importance of temperature difference in climate change impact research. These trends are not only essential for climate, but they are also important for ... -
Conceptual monthly trend polygon methodology and climate change assessments
Şen, Zekai (Taylor & Francis Ltd, 2021)Climate change impact search methodologies, for a single hydro-meteorological record, are based mostly on probabilistic, statistical and stochastic processes. The application of these methodologies requires some restrictive ... -
Fuzzy string matching procedure
Şen, Zekai (Bentham Science Publishers, 2020)Background: There are different methodologies for DNA comparison based on two string algorithms, which are dependent on crisp logical principles, where there is no room for verbal (linguistic) uncertainty. These are ... -
Groundwater recharge level estimation from rainfall record probability match methodology
Şen, Zekai (Springer, 2019)Groundwater reservoirs’ assessment and management studies present more difficulties compared to surface water resources, because their storage media are geological formations, which have spatial heterogeneities that cannot ... -
Improved standard precipitation index and drought characteristics
Şen, Zekai (Inderscience Publishers, 2021)In many regions of the world, and particularly in the eastern Mediterranean region, there is a general precipitation decrease tendency according to the global circulation model (GCM) and the regional climate change models ... -
Innovative equivalent elastic modulus based stress calculation methodology for reinforced concrete columns
Şen, Zekai; Mangır, Atakan (MDPI, 2023)The combination of linearity and elasticity assumptions provides classical calculation procedures for the reinforced concrete (RC) columns and beams against internal and external seismic loads. In these calculation procedures, ... -
Innovative multi-cross trend model and application
Şen, Zekai (Inderscience Publishers, 2022)Abstract This paper presents an innovative multi-cross trend (IMCT) approach based on the number of crossings, which yield not only on the average trends like the classical methodologies but additionally high and low ... -
