Inversion géoacoustique passive en milieux petits fonds à partir de signaux représentatifs des émissions de cétacés

This paper presents a geoacoustic inversion scheme relying on the inversion of signal close to marine mammals vocalizations on a single hydrophone in shallow waters. Our method makes best use of the multipath propagation of vocal calls and of their time-frequency signature to extract an observable used by the inversion algorithm to estimate sea bottom features. This method requires vocalization...

Système d'accès à des bases de données hétérogènes dans le cadre de l'aide à la décision

Decision Support System has, for several years, been a very active domain of research. The deciders of today are faced with an ever increasing flow of data, which is becoming more and more diverse. It is therefore difficult, in a company, for the decision taker to find the data which is necessary for him to make decisions. It is in this context that is placed our study. We propose in this artic...
