AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The modulation spectrum is an efficient representation for describing dynamic information in signals. In this work we investigate how to exploit different elements of the modulation spectrum for extraction of information in automatic recognition of speech ...
This paper investigates the combination of evidence coming from different frequency channels obtained filtering the speech signal at different auditory and modulation frequencies. In our previous work \cite{icassp2008} ...

The asymmetrical multilevel inverters allow to obtain a high resolution together with a good efficiency thanks to the switch hybridization. Nevertheless, the supplies of the cells must be insulated one from each other, which increases the converter complex ...
Normal cellular metabolism produces oxidants which are neutralized within cells by antioxidant enzymes and other antioxidants. An imbalance between oxidants and antioxidants has been postulated to lead to the degeneration of specific populations of neurons ...
In scalar-coupled spin systems where in-phase and antiphase coherences have different lifetimes, the envelopes of spin echoes may feature modulations that are induced by relaxation. These modulations are most pronounced when the couplings that lead to the ...
Reactive oxygen species are considered to contribute to the pathogenesis of Parkinson's disease (PD). In order to study viral vector-mediated overexpression of the antioxidant enzyme glutathione peroxidase (GPX) as a potential neuroprotective approach in b ...
This thesis gives an overview of my work over the last four years on the development of analogue electronic building blocks for the auditory pathway, and their application to some models of processing in the auditory brainstem. The anatomy and physiology o ...
The concentration of reduced glutathione (GSH), an antioxidant, may be altered in various brain diseases. MEGA-PRESS was used to edit for the (1)H NMR signal from GSH in the occipital lobe of 12 normal humans. In all studies, GSH was clearly detected with ...
The structure of a crystal of Sr0.61Ba0.39Nb2O6 has been solved and refined as an incommensurate structure in five-dimensional superspace. The structure is tetragonal, superspace group P4bm(pp1/2; p-p1/2), unit-cell parameters a = 12.4566 (9), c = 7.8698 ( ...
