Inelastic panel zone deformation demands in stell moment resisting frames
Tuna, Mehmet; Topkaya, Cem; Department of Civil Engineering (2012)
Panel zone is one of the significant parts of beam-column connections in steel structures. Until the 1994 Northridge Earthquake, a few experimental research and parametric studies had been carried out to understand the behavior of the panel zones. However, after the Northridge Earthquake, it was observed that beam-column connections were unable to show presumed seismic performance. Therefore, current design codes needed to be revised to improve seismic performance of connections in general and panel zones i...
An Analysis of momentum and mean reversion effects on equity indices
Özbilge, Armağan; Yolcu Okur, Yeliz; Nazlıben, Kamil Korhan; Department of Financial Mathematics (2015)
Momentum and mean-reversion effects have become very popular in finance literature for the last two decades since their presence can generate abnormal profit patterns by applying either relative strength or contrarian trading strategy accordingly. Even though there are some common factor explanations for return reversals, they might not provide the full picture for return persistence. In our theoretical framework, we analyse some of the well-known discrete time momentum studies including the initial one and...
A numerical study on special truss moment frames
Ölmez, Harun Deniz; Topkaya, Cem; Department of Civil Engineering (2009)
A three-phase numerical study was undertaken to address some design issues related with special truss moment frames (STMFs). In the first phase, the design approaches for distribution of shear strength among stories were examined. Multistory STMFs sized based on elastic and inelastic behavior were evaluated from a performance point of view. A set of time history analysis was conducted to investigate performance parameters such as the interstory drift ratio and the plastic rotation at chord member ends. The ...
Modeling monostatic sea clutter at low grazing angles by using method of moments
Özbaş, Emre; Kuzuoğlu, Mustafa; Department of Electrical and Electronics Engineering (2021-2-15)
Scatteringof electromagnetic waves from rough surfaces such as sea surface isanimportantproblem for radarengineers,since aradardeviceshould discriminate returns from the desired object(target)from those scattered by theundesired object, which is rough sea surface studied in this work. Since the sea surface is randomly changing with time for varyingwind speeds, sea clutter problem becomes a stochastic problem. The main goal of this thesis is obtaining a model to calculate the backscattered power f...
Implementation of sensorless vector control drive with current position estimation
Filci, Tayfun; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2016)
In this thesis, an algorithm will be developed and implemented online for the estimation of rotor position from the rotor slot harmonics in stator currents. Experiments will be done on an inverter driven induction motor hardware, and the performance of the position detection algorithm will be evaluated in comparison with commercial encoder outputs.
