BOUDRAA, Abdel-Ouahab; (2017)
More than 30 years after the institution of the moratorium on commercial whaling by the International Whaling Commission, one of the biggest challenges in whale monitoring, e.g. Antarctic Blue Whales (ABW), is assessing ... -
Antarctic Blue Whale Calls Detection Based on an Improved Version of the Stochastic Matched Filter Communication avec acte; ; ; ;BOUDRAA, Abdel-Ouahab (2017)
As a first step to Antarctic Blue Whale monitoring, a new method based on a passive application of the Stochastic Matched Filter (SMF) is developed. To perform Z-call detection in noisy environment, improvements on the ...

While sailing offwind, the trimmer typically adjusts the downwind sail “on the verge of luffing”, occasionally letting the luff of the sail flap. Due to the unsteadiness of the spinnaker itself, maintaining the luff on the ...

Chapitre d'ouvrage scientifique; ;BOT, Patrick; HAUVILLE, Frederic (Editions de l'Ecole Polytechnique, 2013)
The dynamic Fluid Structure Interaction (FSI) of yacht sails submitted to a harmonic pitching motion is numerically investigated to address both issues of aerodynamic unsteadiness and structural deformation. The model ...
