A Comparative study on nonlinear modeling of structural walls
Dursun, Süleyman Eren; Kurç, Özgür; Sucuoğlu, Haluk; Department of Civil Engineering (2018)
The need for tall buildings increases day by day because of many reasons such as increase in population. Representing the behavior of tall buildings under seismic loads is a complicated problem. Thus, in structural engineering, performance based analysis and design approach is generally used for tall buildings which may require nonlinear analysis of buildings. In such an analysis, however, modeling of structural walls has several challenges especially for the ones with irregular cross sections. Therefore, t...
A comparative study on Kalman filtering techniques designed for state estimation of industrial AC drive systems
Akin, B; Orguner, Umut; Ersak, A (2004-06-05)
In this paper, two different Kalman Filtering techniques, Unscented Kalman Filter (UKF) and Extended Kalman Filter (EKF) are investigated and compared both experimentally and theoretically. These non-linear, stochastic observers are employed as a state estimation tool in field-oriented control (FOC) of sensorless AC drives in this work. Using the superiorities of Kalman filtering, rotor speed and dq-axis fluxes of an induction motor are estimated only with the sensed stator currents and voltages information...
A comparative study on pose estimation algorithms using visual data
Çetinkaya, Güven; Alatan, Abdullah Aydın; Department of Electrical and Electronics Engineering (2012)
Computation of the position and orientation of an object with respect to a camera from its images is called pose estimation problem. Pose estimation is one of the major problems in computer vision, robotics and photogrammetry. Object tracking, object recognition, self-localization of robots are typical examples for the use of pose estimation. Determining the pose of an object from its projections requires 3D model of an object in its own reference system, the camera parameters and 2D image of the object. Mo...
A comparative study on ILP-based concept discovery systems
Kavurucu, Yusuf; Karagöz, Pınar; Toroslu, İsmail Hakkı (2011-09-01)
Inductive Logic Programming (ILP) studies learning from examples, within the framework provided by clausal logic. ILP has become a popular subject in the field of data mining due to its ability to discover patterns in relational domains. Several ILP-based concept discovery systems are developed which employs various search strategies, heuristics and language pattern limitations. LINUS, GOLEM, CIGOL, MIS, FOIL, PROGOL, ALEPH and WARMR are well-known ILP-based systems. In this work, firstly introductory infor...
A comparative study of anisotropic hyperelastic models of biological soft tissues
Açan, Alp Kağan; Dal, Hüsnü; Department of Mechanical Engineering (2021-8)
In the last two decades, there has been significant growth of interest in the mechanical behavior of biological soft tissues approached from the continuum mechanical perspective. A plenty of constitutive models have been proposed that represent the anisotropic hyperelastic behavior of biological soft tissues. Generally, invariant and fiber dispersion-based models are two main categories considered during the modeling steps. Among the anisotropic models, fiber dispersion-based constitutive models are known t...
