The controlled drift detector as an x-ray imaging device for diffraction enhanced imaging
Özkan, Çiğdem; Serin, Meltem; Department of Physics (2009)
Diffraction Enhanced Imaging (DEI) is an X-ray imaging technique providing specific information about the molecular structure of a tissue by means of coherently scattered photons. A Controlled Drift Detector (CDD) is a novel 2D silicon imager developed to be used in X-ray imaging techniques. In this work a final (complete and detailed) analysis of DEI data taken with the CDD in the ELETTRA synchrotron light source facility in Trieste (Italy) in 2005, is presented and the applicability of both this new techn...
A simulation study on marginalized transition random effects models for multivariate longitudinal binary data
Yalçınöz, Zerrin; İlk Dağ, Özlem; Department of Statistics (2008)
In this thesis, a simulation study is held and a statistical model is fitted to the simulated data. This data is assumed to be the satisfaction of the customers who withdraw their salary from a particular bank. It is a longitudinal data which has bivariate and binary response. It is assumed to be collected from 200 individuals at four different time points. In such data sets, two types of dependence -the dependence within subject measurements and the dependence between responses- are important and these are...
Investigation of electromigration induced hillock and edge void dynamics on the interconnect surface by computer simulation
Çelik, Aytaç; Oğurtanı, Tarık Ö.; Department of Metallurgical and Materials Engineering (2004)
The Electromigration-induced failure of metallic interconnects is a complicated process, which involves flux divergence, vacancy and atom accumulation with or without compositional variations, void and hillocks nucleation, growth and shape changes. Hillocks and surface void dynamics in connection with the critical morphological evaluation have been investigated in order to understand the conditions under which premature failure of metallic thin interconnects occur. In this thesis, an interconnect is idealiz...

Correctly accounting for the uncertainty in ground-motion prediction is a critical component of probabilistic seismic-hazard analysis (PSHA). This prediction is commonly achieved using empirical ground-motion prediction equations. The differences between the observed and predicted ground-motion parameters are generally assumed to follow a normal distribution with a mean of zero and a standard deviation sigma. Recent work has focused on the development of partially nonergodic PSHA, where the repeatable effec...
An adaptive PHD filter for tracking with unknown sensor characteristics
Zhao, Yuxin; Yin, Feng; Gunnarsson, Fredrik; Amirijoo, Mehdi; Özkan, Emre; Gustafsson, Fredrik (2013-07-09)
The particle filter provides a general solution to the nonlinear filtering problem with arbitrarily accuracy. However, the curse of dimensionality prevents its application in cases where the state dimensionality is high. Further, estimation of stationary parameters is a known challenge in a particle filter framework. We suggest a marginalization approach for the case of unknown noise distribution parameters that avoid both aforementioned problem. First, the standard approach of augmenting the state vector w...
