Design of computationally efficient yet perceptually realistic room auralisation algorithms require a careful selection of the early reflections to be auralised. A perception-based simplification algorithm is presented for the selection of the early reflections using a criterion which depends both on the arrival time and on the angle of incidence of the early reflection with respect to the listener. Results of two subjective tests for the evaluation of the proposed algorithm are presented. The proposed algorithm is shown to provide a significant reduction in the number of early reflections without significantly affecting the tested localisational or spatial qualities of auralisation.

Probabilistic approach to assess URM walls with openings using discrete rigid block analysis (D-RBA) Pulatsu, Bora; Gonen, Semih; Parisi, Fulvio; Erdogmus, Ece; Tuncay, Kağan; Funari, Marco Francesco; Lourenco, Paulo B. (2022-12-01) This study aims to improve our current understanding of the seismic assessment of load-bearing unreinforced masonry (URM) systems by proposing a probabilistic computational modeling framework using the discrete element method (DEM). The main objective is to predict the structural behavior and capacity of URM walls with openings subjected to lateral loading, considering uncertainties in material properties. The proposed modeling strategy represents masonry as an assembly of rigid blocks interacting along the...
Retraction Free Motion Approach and Its Application in Automated Robotic Edge Finishing and Inspection Processes Nemer, Mahmoud; Konukseven, Erhan İlhan (null; 2016-12-15) In this paper, a motion generation algorithm for a six Degrees of Freedom (DoF) robotic hand in a static environment is presented. The purpose of developing this method is to be used in the path generation of the end-effector for edge finishing and inspection processes by utilizing the CAD model of the considered workpiece. Nonetheless, the proposed algorithm may be extended to be applicable for other similar manufacturing processes. A software package programmed in the application programming interface (AP...
Perceptual quality preserving adversarial attacks Aksoy, Bilgin; Temizel, Alptekin; Department of Modeling and Simulation (2019) Deep learning is used in various succesful computer vision applications such as image classification. Deep neural networks (DNN) especially convolutional neural networks have reached above human level accuracy rates for image classification tasks. While DNNs have solved the image classification task and enabled its use in many practical applications, recent research has unveiled some properties which could degrade their performance. Adversarial images are samples that are intentionally modified by adding no...
Extended Target Tracking Using Polynomials With Applications to Road-Map Estimation Lundquist, Christian; Orguner, Umut; Gustafsson, Fredrik (Institute of Electrical and Electronics Engineers (IEEE), 2011-01-01) This paper presents an extended target tracking framework which uses polynomials in order to model extended objects in the scene of interest from imagery sensor data. State-space models are proposed for the extended objects which enables the use of Kalman filters in tracking. Different methodologies of designing measurement equations are investigated. A general target tracking algorithm that utilizes a specific data association method for the extended targets is presented. The overall algorithm must always ...
Scattering delay networks with aperture size control for simulating coupled volume acoustics Atalay, Timuçin Berk; Hacıhabiboğlu, Hüseyin; Department of Modeling and Simulation (2019) Artificial reverberators provide a computationally viable alternative to full-scale room acoustics simulation methods when used in interactive, immersive systems. Scattering delay network (SDN) is a relatively recent artificial reverberator that allows direct parametric control over the geometry of a simulated rectangular enclosure as well the directional characteristics of the simulated sound sources and microphones. Coupled volume SDN aims to extend the SDN structure for enclosures coupled via an aperture...
