Estimation of effective parameters and operational response of tuned vibration absorbers Özden, Hasan Can; Özgen, Gökhan Osman; Department of Mechanical Engineering (2019) In this study, swing up and stabilization of on/off type of cold gas thruster driven inverted pendulum is accomplished. First, pulse width modulator (PWM) design method is generated to obtain quasi-linear thrust output from on/off type of thruster. Than, single axis angle controller is designed. Designed angle controller and PWM scheme are tested and verified on single axis angle control test setup. Finally, an other freedom is attached to single axis test setup and rotary inverted pendulum (Furuta Pendulum...
Estimation of optimum isolator parameters for effective mitigation of seismic risk for bridges Karalar, M.; Dicleli, Murat (2010-07-15) In this study, closed form equations as functions of the isolator, bridge and ground motion properties are formulated to calculate the optimum characteristic strength, Q(d) and post-elastic stiffness, k(d), of the isolator to minimize the maximum isolator displacement (MID) and force (MIF) for seismic isolated bridges (SIBs). This formulation required more than 13000 nonlinear time history analyses of simplified SIB models. The analyses results revealed that the optimum Qd and kd are highly dependent on the...
Estimation of probability of failure for stepped path sliding with three joint sets Korgan, H; Ozgenoglu, O (1999-08-28) In jointed rock masses, sliding along a stepped path surface formed by two or more joint sets and sometimes shearing through the intact rock portion between the joints, is much likely to occur than sliding along single continuous surface. Although it has been focused on the two-joint set (i.e. one major and one cross joint set) stepped path sliding problem, there is little work on the analysis of stepped path sliding with three joint sets. In this paper, a simulation model developed for the analysis of step...
Estimation of earthquake damage probabilities for reinforced concrete buildings Yücemen, Mehmet Semih (2003-05-13) Due to uncertainties involved both in the occurrence of earthquakes and in structural response, earthquake damage prediction has to be treated in a probabilistic manner. In this study two statistical methods are presented for the prediction of potential seismic damage to low and mid-rise reinforced concrete buildings in Turkey. These methods are based on the utilization of damage probability matrices and reliability theory. The damage data compiled during recent earthquakes that occurred in Turkey are used ...
Estimation of time-dependent link costs using GPS track data Ünsal, Ahmet Dündar; Usul, Nurünnisa; Department of Geodetic and Geographical Information Technologies (2006) Intelligent Transport Systems (ITS) are becoming a part of our daily lives in various forms of application. Their success depends highly on the accuracy of the digital data they use. In networks where characteristics change by time, time-based network analysis algorithms provide results that are more accurate. However, these analyses require time-based travel speed data to provide accurate results. Conventionally, traffic data are usually obtained using the data provided from loop-detectors. These detectors...
