Wideband Direction of Arrival Estimation with Sparse Linear Arrays

This paper concerns wideband direction of arrival (DoA) estimation with sparse linear arrays (SLAs). We rely on the assumption that the power spectrum of the wideband sources is the same up to a scaling factor, which could in theory allow us to resolve not only more sources than the number of antennas but also more sources than the number of...

Design and evaluation of a virtual environment for the treatment of anger

Cognitive-behavioural therapy is often used for anger treatment. An important element of this therapy is exposure to anger evoking stimuli. In this paper virtual reality is put forward as a technology that can effectively create these stimuli by exposing patients to social scenes that include anger stressors such as aggressive dialogues with...
