a three dimensional, compressible, steady, one phase flow of reactant-product mixture in the air side electrode of proton exchange membrane fuel cell (pemfc) is numerically studied in this paper. the mixture is composed of three species: oxygen, nitrogen and water vapor. the performance of the cell is enhanced by partial blockage of the flow field channels. various types of these blocks also ca...

AUDIENCE-PERFORMER INTERACTION There is a very traditional set of expectations to an audience of a performance [5] and augmenting the audience with technologies can introduce complex interaction.

We propose a general methodology to design a robust voice activity detector that suits the needs of the speech enhancement system it is dedicated to. More than imposing rules, we initiate ideas on how to perform the analysis of the requirements for the Voice Activity Detection (VAD) and how to choose a reference, and evaluate the performances of the explored solutions in order to choose the one...
