Developments in immersive audio technologies have been evolving in two directions: physicallymotivated and perceptually-motivated systems. Physically motivated techniques aim to reproduce a physically accurate approximation of desired sound fields by employing a very high equipment load and sophisticated computationally intensive algorithms. Perceptually-motivated techniques, on the other hand, aim to render only the perceptually relevant aspects of the sound scene by means of modest computational and equipment load. This article presents an overview of perceptually motivated techniques, with a focus on multichannel audio recording and reproduction, audio source and reflection culling, and artificial reverberators.

Broadband microwave diode mixer design and implementation Koç, Emrah; Demir, Şimşek; Department of Electrical and Electronics Engineering (2016) Mixers play a critical role in design and development of wireless communication systems. Demanding requirements of the mixers are improvements in conversion efficiency, bandwidth, cost, and linearity. Schottky barrier diodes attract mixer designers due to their favorable characteristics leading to wide bandwidth, low-cost, and high efficient designs. This thesis demonstrates the design and implementation of two passive mixing circuits using Schottky barrier diodes at microwave frequencies. The first circuit...
Improving the accuracy of a mobile robot for localization and mapping of an unknown environment Gümrükcü, Gülşah; Konukseven, Erhan İlhan; Department of Mechanical Engineering (2003) This thesis deals with sensor based motion planning of a mobile robot for localization in an unknown environment. Using the developed algorithm the robot may construct the map (GVG) of any bounded environment, and the minimum distance between any two locations in the mapped environment can be determined. In addition, the accuracy of the robot, facing dead-reckoning error can be improved. With this study, the mobile robot finds the optimum path between any two locations in any bounded environment and traces ...
Simulation of turbulence induced sound generation inside stenosed femoral artery models with different severities and eccentricities Ozden, Kamil; Yazıcıoğlu, Yiğit; Sert, Cüneyt (2021-09-01) Background and objectives: Recent developments of low-cost, compact acoustic sensors, advanced signal processing tools and powerful computational resources allow researchers design new scoring systems for acoustic detection of arterial stenoses. In this study, numerical simulations of blood flow inside stenosed arteries are performed to understand the effect of stenosis severity and eccentricity on the turbulence induced wall pressure fluctuations and the generated sound. Methods: Axisymmetric and eccentric...
Turbomachinery Noise Radiation through the Engine Exhaust (TURNEX) Özyörük, Yusuf(2005-1-01) Research is needed to develop innovative concepts and enabling technologies to reduce aeroengine noise at source. Turbomachinery noise radiating from the bypass and core nozzles is becoming the dominant noise source on modern aircraft, but, while recent EU research programmes have made significant progress in reducing both the generation of turbbmachinery noise and the radiation of noise from the intake, little work has been conducted on reducing the radiation of turbomachinery noise from exhaust nozzles. ...
Control electronics for mems gyroscopes and its implementation in a CMOS technology Eminoğlu, Burak; Akın, Tayfun; Department of Electrical and Electronics Engineering (2011) This thesis, for the first time in literature, introduces a comprehensive study about analog controller designs for MEMS vibratory gyroscopes. A controller of a MEMS gyroscope is mandatory for robust operation, which is insensitive to sensor parameters and ambient con- ditions. Errors in the controller design not only deteriorate transient performance, such as settling time and overshoot, but also cause performance degradation due to stability problems. Accordingly, true controller design for a gyroscope is...
