We present a preconditioning technique, called support-graph preconditioning, and use it to analyze two classes of preconditioners. The technique was first described in a talk by Pravin Vaidya, who did not formally publish his results. Vaidya used the technique to devise and analyze a class of novel preconditioners. The technique was later extended by Gremban and Miller, who used it in the deve...

An extension of conventional speaker segmentation framework is presented for a scenario in which a number of microphones record the activity of speakers present at a meeting (one microphone per speaker). Although each microphone can receive speech from both the participant wearing the microphone (local speech) and other participants (cross-talk), the recorded audio can be broadly classified in ...

Thomas Brihaye Université de Mons-Hainaut Model-Checking, bisimulation and word combinatorics. Abstract. In this talk we explain briefly what model-checking is. Then we recall the notion of bisimulation and explain why the study of bisimulations is relevant in the context of model-checking. In particular we focus on bisimulations of dynamical systems and we explain how the dynamics of these sys...

MEG(magnetoencephalogram) is the powerful technique for the analysis of brain activity. The magnetic signal doesn't reduce in a brain, and we can obtain the accurate information about the position of the signal source by using MEG. Our aim of this study is the analysis of the stereoscopic e ect in the brain. In this report, we will talk about our MEG measurement system and our pseudo stereograp...

An optimal design technique of loudspeaker arrays for cross-talk cancellation with application in three-dimensional audio is presented. An array focusing scheme is presented on the basis of the inverse propagation that relates the transducers to a set of chosen control points. Tikhonov regularization is employed in designing the inverse cancellation filters. An extensive analysis is conducted t...

In this paper, we propose a novel double-talk detection (DTD) technique based on a soft decision in the frequency domain. The proposed method provides an efficient procedure to detect the double-talk situation by the use of the global near-end speech presence probability (GNSPP) and voice activity detection (VAD) of the near-end and far-end signal. Specifically, the GNSPP is derived based on a ...
