Seismic loss estimation studies require fragility curves which are usually derived using ground motion datasets. Ground motion records can be either in the form of recorded or simulated time histories compatible with regional seismicity. The main purpose of this study is to investigate the use of alternative ground motion datasets (simulated and real) on the fragility curves. Simulated dataset is prepared considering regional seismicity parameters corresponding to Erzincan using the stochastic finite-fault ...
Derivation of the parallel PIC/MCC numerical code and its application to the kinetic analysis of photoresonance plasma and the problem of identification of impurities within the PLES method
Kuşoğlu Sarıkaya, Cemre; Rafatov, İsmail; Department of Physics (2017)
1d3v Particle in Cell/Monte Carlo Collision (PIC/MCC) code for numerical simulations of gas discharge plasma was developed. The efficiency of the code was increased by its parallelization using Open MPI. In order to verify the applicability of the code, the benchmark tests were performed under the RF capacitively coupled discharge conditions. The effects of the particle weighting and the Courant number on the computed plasma properties were examined and the convergence of the numerical method with respect t...
Derivation and analysis of near field tofar field transformation algorithm for spherical scanning
Korkmaz, Hülya; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2019)
This thesis focuses on the improvement of a far field transformation algorithm of spherical near field scanning by using different quadrature techniques for numerical integration process. In this thesis, spherical vector wave expansion of E field is studied and numerical calculation for expansion coefficients of E field is performed. In the scope of this study quadrature techniques like Gauss, Trapezoid and Simpsons are investigated and advantages and disadvantages of these techniques are discussed. A decis...
Analysis of a New Method for Measurement of Parameters of Real Thermoelectric Module Employed in Medical Cooler for Renal Hypothermia
AHISKA, RAŞİT; Ahiska, G.; Ahiska, K. (Informa UK Limited, 2009-01-01)
In the present study, a new method for searching all exit parameters of the thermoelectric module has been realized. The new method is based on measurement of thermo-emf of a working module and comparing the results obtained with those of classical methods. The new method is used for investigation of the values of parameters of a standard thermoelectric module of Melcor with production code of CP1.0-127-05L, used in medical coolers for renal hypothermia. The theoretical results calculated by the means of ne...
Verification of empirically determined support systems of the Kılıçlar highway tunnel by numerical modelling
Çelik, Gözde; Topal, Tamer; Department of Geological Engineering (2011)
The aim of this study is to determine the geological and geotechnical characteristics of Kılıçlar Tunnel on Ankara-Kırıkkale Highway, to suggest the appropriate support and excavation systems and verify these suggested support systems via numerical modeling. The length of Kılıçlar Tunnel is 1110 m. The width of tunnel is 16 m, the height is 10 m and the maximum overburden height is 90 m. Since Ankara-Kırıkkale Highway consists of 2x3 lanes, the tunnel is designed as a twin tube tunnel. Kılıçlar Tunnel is pl...
