General direction-of-arrival tracking with acoustic nodes
Volkan Cevher,James H. McClellan +1 more
TL;DR: A new model is introduced that incorporates an acceleration component along the heading direction of the target and it is shown that by incorporating the acceleration into the state vector, the tracking performance can be improved in certain cases as expected.

Simultaneous-Speaker Voice Activity Detection and Localization Using Mid-Fusion of SVM and HMMs
TL;DR: A mid-fusion approach to perform both VAD and SSL for multiple active and inactive speakers is proposed by analyzing the individual speakers' spatio-temporal activities and mouth movements by using Support Vector Machines and Hidden Markov Models for assessing the video and audio modalities through an RGB camera and a microphone array.

Ulf Micheland,Stefan Funke +1 more
TL;DR: In this paper, a new data analysis method SODIX (SOurce DIrectivity modelling in cross-spectral matriX) was developed for this purpose and applied to the experimental data obtained with a high-bypass ratio turbofan engine in an open air test bed.

Direction of arrival estimation using music algorithm
Revati Joshi,Ashwinikumar Dhande +1 more
TL;DR: Analysis of the performance of MUSIC (Multiple Signal Classification) algorithm for DOA estimation shows that MUSIC provide better angular resolution for increasing number of array element, distance between array element and number of samples.
Dissertation
Seafloor depth estimation by means of interferometric synthetic aperture sonar
TL;DR: A novel solution for the depth estimate using sidelooking sonar is presented, and an elegant solution to co-registration and unwrapping is found by interpolating the sonar data in ground-range.
