This paper proposes a framework model for the analysis of sound source localisation under the precedence effect using Gaussian mixtures. The model quantifies the effect of the lagging sound over the angular position and the width of the perceived auditory event, and incorporates some well-known aspects of the precedence effect in a single framework. Two sound source localisation experiments were carried out in order to show the utility of the proposed model. In the first experiment, the localisation accuracy for single sound sources was measured. In the second experiment, the subjects localised spectrally coherent lead-lag stimulus pairs with different angular separations. The responses were analysed using the proposed model. It is shown that the model can be used for assessing the fusion, localisation dominance, and the lag discrimination suppression aspects of the precedence effect as well as the associated widening of the auditory event.

An Efficient Approach for Evaluation of Multilayered Media Green's Functions ÖZGÜN, ÖZLEM; Li, Chao; Kuzuoğlu, Mustafa; Mittra, Raj (2021-01-01) © 2021 IEEE.In this study, a novel approach is presented for efficient evaluation of Sommerfeld integrals arising in spatial-domain Green's functions in planar multilayered media. This approach allows us to tackle the difficulties encountered during the integration of the Sommerfeld integrals, which exhibit highly oscillatory and slowly decaying nature occurring especially at very high frequencies, e.g., at millimeter waves, that are finding increasing use in applications such as 5G and beyond. The oscillat...
AN ANALYSIS TO IMPROVE STABILITY OF DRIVE-MODE OSCILLATIONS IN CAPACITIVE VIBRATORY MEMS GYROSCOPES Alper, S. E.; Sahin, K.; Akın, Tayfun (2009-01-29) This paper presents an analysis showing that it is possible to determine the factors that limit the stability of drive-mode oscillations of a vibratory MEMS gyroscope with precise modeling. Specifically, unwanted electrical resonance characteristics of the gyroscope drive-mode are analyzed together with analytical expressions, whereas the results of the theoretical analyses are verified both by simulations and measurements, which agree very well. It is demonstrated that the stability of the drive-mode oscil...
An algorithm for line matching in an image by mapping into an n-dimensional vector space Sultanov, Raiymbek; Atakan, Ahmet; Ismailova, Rita (2019-01-01) This paper proposes a minimal length difference algorithm for construction of a line in an image by solving the problem of optimal contour approximation. In this algorithm, a method for finding interest points is proposed, and the object matching (classification) is done by mapping interest points onto a vector space. In cases where the lines in the representation of the images are not smooth, the algorithm converges rapidly. The results of the experiments showed that for convergence of the contour simplifi...
Application of ODSA to population calculation Ulukaya, Mustafa; Demirbaş, Kerim; Department of Electrical and Electronics Engineering (2006) In this thesis, Optimum Decoding-based Smoothing Algorithm (ODSA) is applied to well-known Discrete Lotka-Volterra Model. The performance of the algorithm is investigated for various parameters by simulations. Moreover, ODSA is compared with the SIR Particle Filter Algorithm. The advantages and disadvantages of the both algorithms are presented.
Constrained discrete-time optimal control of uncertain systems with adaptive Lyapunov redesign ALTINTAS, Oguz Han; Turgut, Ali Emre (2021-01-01) All rights reserved.In this paper, the conventional estimation-based receding horizon control paradigm is enhanced by using functional approximation, the adaptive modifications on state estimation and convex projection notion from optimization theory. The mathematical formalism of parameter adaptation and uncertainty estimation procedure are based on the redesign of optimal state estimation in discrete-time. By using Lyapunov stability theory, it is shown that the online approximation of uncertainties acti...
