The inputs to the probabilistic seismic-hazard analysis (PSHA) contain large uncertainties regarding the seismic source model parameters; therefore, results may vary significantly due to subjective judgment and interpretation of the limited data. The objective of this study is to show the effect of seismic source models on the hazard results by quantifying the differences in the design ground motions for different hazard levels at different locations around the North Anatolian fault. Analysis showed the variances in the hazard results obtained by different seismic source models are closely correlated with the location of the site and hazard level. Additionally, sensitivity of the hazard results to the uncertainties involved in each source parameter, especially the source zone boundaries, annual slip rate, maximum and minimum magnitudes, fault width, b-value, and scenario weights are analyzed and presented to provide insight on the relative contribution of source or fault parameters to the PSHA results.

Effects of seismic source model parameters on the probabilistic seismic hazard assessment results Vakilinezhad, Marjan; Gülerce, Zeynep; Department of Civil Engineering (2015) The inputs to the Probabilistic Seismic Hazard Analysis (PSHA) contain large uncertainties regarding the seismic source model parameters; therefore, the results may vary significantly due to subjective judgment and interpretation of the limited data. The objective of this study is to show the effect of seismic source model on the hazard results by quantifying the difference in the design ground motions for different risk levels at different locations around an active tectonic structure. Analysis showed that...
Effect of watershed partitioning on hydrologic parameters and estimation of hydrograph of an ungauged basin: a case study in Gokirmak and Kocanaz, Turkey Kocyigit, Musteyde Baduna; Akay, Huseyin; Yanmaz, Ali Melih (Springer Science and Business Media LLC, 2017-08-01) The main goal of this study is to investigate the effect of the size of the subbasins of a watershed on the hydrologic parameters and their spatial variability in an estimation of the hydrologic parameters and hydrograph of a neighbouring ungauged basin. In this paper, Hydrologic Engineering Center-Hydrologic Modelling System (HEC-HMS), a semi-distributed hydrologic model, is used to calibrate and cross-validate two flood events occurred in 1998 and then validate four other flood events occurred in 1991, 19...
Effect of thermal induced flexural strain cycles on the low cycle fatigue performance of integral bridge steel H-piles Karalar, Memduh; Dicleli, Murat (2016-10-01) Close examination of the field measurement data for integral bridges revealed that the measured cyclic flexural strains in steel H-piles at the abutments due to thermal fluctuations consist of large amplitude, primary small amplitude and secondary small amplitude cycles. The effect of the small amplitude strain cycles on the low cycle fatigue life of these steel H-piles has not been extensively studied yet. Accordingly, to investigate the effect of the small amplitude strain cycles on the low cycle fatigue ...
Effects of supersymmetric CP phases on chargino-pair production via the Drell-Yan process at the CERN LHC Cankocak, K; Aydemir, A; Sever, Ramazan (American Physical Society (APS), 2004-04-01) We compute the rates for pp annihilation into chargino pairs via the Drell-Yan process taking into account the effects of supersymmetric soft phases, at a proton-proton collider. In particular, the phase of the mu parameter gains direct accessibility via the production of dissimilar charginos. The phases of the trilinear soft masses do not have a significant effect on the cross sections.
EFFECT OF MOBILITY ON (IV) CHARACTERISTICS OF GaAs MESFET Saidi, Y.; Alliouat, W.; Hamma, I.; Zaabat, M.; Azizi, M.; Azizi, C. (2011-09-10) We present in this paper an analytical model of the current voltage (I-V) characteristics for submicron GaAs MESFET transistors. This model takes account the analysis of the charge distribution in the active region and incorporate a field depended electron mobility, velocity saturation and charge build-up in the channel.we propose In this framework an algorithm of simulation based on mathematical expressions obtained previously. The results obtained of the model are discussed and compared with those of the ...
