Efficient Classification of Noisy Speech Using Neural Networks (2003)

C. Shao, M. Bouchard

The classification of active speech vs. inactive speech in noisy speech is an important part of speech applications, typically in order to achieve a lower bit-rate. In this work, the error rates for...

Recursive Least-Squares Algorithms with Good Numerical Stability for Multichannel Active Noise Control (2001)

F. Yu, M. Bouchard

Some recursive least-squares algorithms for multichannel active noise control have recently been introduced, including computationally efficient (i.e. "fast") versions. However, these...

Recursive Least-Squares Algorithms with Improved Numerical Stability and Constrained Least-Squares Algorithms for Multichannel Active Noise Control Systems (2000)

M. Bouchard

This paper deals with the convergence of adaptive FIR filters used for multichannel active noise control (ANC) systems [1]. In a recent paper [2], recursive least-squares (RLS) algorithms and...

A Comparison of Software Tools for the Implementation of Spatial Sounds in Virtual Environments (2000)

F. Yu, M. Bouchard

this paper, we review some of the current software tools available for creating the illusion of threedimensional sounds in virtual environments using binaural technology, and we attempt to evaluate...

Multichannel Active Noise Control Algorithms Using Inverse Filters (2000)

F. Yu, M. Bouchard

In this paper, a simple inverse structure for multichannel active noise control (ANC) is introduced. This structure, combined with adaptive FIR filters and filtered-x LMS--based algorithms, can...

Multichannel Active Noise Control Algorithms Using Inverse Filters (2000)

M. Bouchard, Yu F.

this paper, a simple multichannel algorithm that can both reduce the computational load and increase the convergence speed compared to the multichannel filtered-x LMS algorithm or its fast exact...

Solvent history dependence of gramicidin-lipid interactions: a Raman and infrared spectroscopic study.

Bouchard, M, Auger, M

We have investigated the interactions between gramicidin and a model membrane composed of one phospholipid, dimyristoylphosphatidylcholine, as a function of the cosolubilization solvent and...

High-speed magic angle spinning solid-state 1H nuclear magnetic resonance study of the conformation of gramicidin A in lipid bilayers.

Bouchard, M, Davis, J H, Auger, M

One- and two-dimensional solid-state 1H nuclear magnetic resonance spectra of gramicidin A incorporated in a dimyristoylphosphatidylcholine membrane have been obtained with use of high-speed magic...

Solvent effects on the conformation of the transmembrane peptide gramicidin A: insights from electrospray ionization mass spectrometry.

Bouchard, M, Benjamin, D R, Tito, P, Robinson, C V, Dobson, C M

The binding of sodium ions to the transmembrane channel peptide gramicidin A has permitted the use of electrospray ionization mass spectrometry to study its conformation in different solvent...

Characterization of the oligomeric states of insulin in self-assembly and amyloid fibril formation by mass spectrometry.

Nettleton, E J, Tito, P, Sunde, M, Bouchard, M, Dobson, C M, Robinson, C V
