The goal of this study is to model rainfall-runoff process using HEC-HMS developed by U.S. Army Corps of Engineers for the 10,508 km2 catchment that has E01A012-Yenicegörüce stream gage at its outlet which is located just at the upstream of the point where Meric and Ergene Rivers meet. This study is conducted as a part of 115Y064 numbered “Development of a geographical information systems based decision-making tool for water quality management of Ergene watershed using pollutant fingerprints” project funded by TÜBİTAK. First, meteorological parameters such as daily precipitation and temperature, and daily streamflow data that are observed in and around the study catchment are collected. Then land use, hydrologic soil groups and digital elevation data of the catchment are collected and integrated into Geographic Information System (GIS) environment. Digital maps compiled in GIS environment were transferred into WMS for the calculation of basin parameters, and then the hydrological model for the basin is developed in HEC-HMS using these data. The model is calibrated using daily streamflow values of 1997-2002 and validated for 2003-2005 data. The model results obtained at the Yenicegoruce stream gage has Nash-Sutcliffe Efficiency (NSE) values of 0.8 and 0.75 for calibration and validation, respectively. Hydrological models for Hayrabolu, Luleburgaz and Inanli sub-catchments represented by stream gages D01A008, E01A006 and E01A012, respectively are developed and calibrated as well. Model performances are evaluated using statistical measures such as NSE values and correlations.

Understanding consumer innovativeness via theory of goal directed behavior: an investigation of factors affecting adoption of online games
Baybaş, Gülnur; Yılmaz, Cengiz; Department of Business Administration (2015)
This study aims to analyze the factors behind adoption of online games, using a theoretical foundation based mostly on the theory of goal-directed behavior and diffusion of innovations model. Factors affecting the adoption behavior are determined on the basis of the goal directed behavior theory, and differences between adopter categories of online game buyers are investigated by applying Rogers’ diffusion of innovations (DOI) theory. Online survey was conducted to reach target group by using social media a...
Synthesis of compliant bistable four-link mechanisms for two positions
Subaşı, Levent; Söylemez, Eres; Department of Mechanical Engineering (2005)
The aim of this study is to present a design approach for compliant bistable four-link mechanisms. The design constraints are the two positions of the mechanism, the force required to snap between the positions and the fatigue life of the designed mechanism. The theory presented here will be applied to the door lock mechanism used in commercial dishwashers, which is originally designed as a rigid inverted slider crank mechanism snapping between two positions with the force applied by a spring. The mechanism...
Modeling and Simulation of High Speed Railway Vehicle Dynamics
Tuğçe, Yüksel; Ünlüsoy, Yavuz Samim (null; 2015-03-04)
This study aims to provide mathematical model(s) for the simulation of high speed railway vehicles. The dynamic behavior of a high speed train is divided into three uncoupled motions: vertical, lateral, and longitudinal. Two models with different complexities are used to simulate vertical plane response of the vehicle to track vertical irregularities. Different wheel-rail contact formulations are utilized to simulate the lateral plane motion of the vehicle on tangent and curved tracks. For both vertical and...
Design optimization in chemically reacting flows
Yumuşak, M.; Eyi, Sinan (2011-12-01)
The objective of this study is to develop a reliable and efficient design tool that can be used in chemically reacting flows. The flow analysis is based on axisymmetric Euler and the finite rate chemical reaction equations. These coupled equations are solved by using Newton's method. Both numerical and analytical methods are used to calculate Jacobian matrices. Sensitivities are evaluated by using adjoint method. The performance of the optimization method is demonstrated for a rocket motor nozzle design. © ...
Comparison of different yield criteria in various deep drawn cups
Cogun, Ferah; Darendeliler, Haluk (Springer Science and Business Media LLC, 2017-03-01)
The aim of the study is to evaluate the performance of three recent yield criteria namely; BBC2008-8p, Yld2003-8p, Hu2003 through the simulation of the hemispherical, cylindrical and square cup drawing processes by comparing the results with the ones obtained by using the von Mises criterion for the isotropic, kinematic and combined hardening and the Hill'48 criterion. For this purpose, two different sheet materials, SS304 stainless steel and DKP6112 steel, and various punch travels were used in the simulat...
