    • Passive stochastic matched filter for Antarctic blue whale call detection 
      Article dans une revue avec comité de lecture
      BOUFFAUT, Léa; DRÉO, Richard; LABAT, Valérie; BARRUOL, Guilhem; ccBOUDRAA, Abdel-Ouahab (Acoustical Society of America, 2018)
      As a first step to Antarctic blue whale (ABW) monitoring using passive acoustics, a method based on the stochastic matched filter (SMF) is proposed. Derived from the matched filter (MF), this filter-based denoising method ...
    • Efficient optimization procedure in non-linear fluid-structure interaction problem: Application to mainsail trimming in upwind conditions 
      Article dans une revue avec comité de lecture
      SACHER, Matthieu; DUVIGNEAU, Régis; LE MAÎTRE, Olivier; AUBIN, Nicolas; DURAND, Mathieu; ccHAUVILLE, Frederic (Elsevier, 2017)
      This paper investigates the use of Gaussian processes to solve sail trimming optimization problems. The Gaussian process, used to model the dependence of the performance with the trimming parameters, is constructed from a ...
    • Optimisation de la loi de calage d’un propulseur cycloïdal 
      Communication avec acte
      LECUYER-LE BRIS, Romain; DENISET, François; FASSE, Guillaume; ccHAUVILLE, Frederic (2018)
      Les propulseurs cycloïdaux sont caractérisés par la rotation de plusieurs pales autour d’un axe vertical, associée à un mouvement de chaque pale autour de son axe propre. L’objet de cet article concerne l’étude des lois ...
    • Remote blue whale call detection using a passive version of the stochastic matched filter paper 
      Communication avec acte
      BOUFFAUT, Léa; DREO, Richard; LABAT, Valérie; ccBOUDRAA, Abdel-Ouahab; BARRUOL, Guilhem (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 ...
    • Experimental and numerical trimming optimizations for a mainsail in upwind conditions 
      Communication avec acte
      SACHER, Matthieu; DUVIGNEAU, Régis; LE MAITRE, Olivier; AUBIN, Nicolas; DURAND, Mathieu; ccHAUVILLE, Frederic (2016)
      This paper investigates the use of meta-models for optimizing sails trimming. A Gaussian process is used to robustly approximate the dependence of the performance with the trimming parameters to be optimized. The Gaussian ...
    • Modal Analysis of Pressures on a Full-Scale Spinnaker 
      Communication avec acte
      DEPARDAY, Julien; AUGIER, Benoit; RABAUD, Marc; MOTTA, Dario; LE PELLEY, David; ccBOT, Patrick; ccHAUVILLE, Frederic (2016)
      While sailing offwind, the trimmer typically adjusts the downwind sail "on the verge of luffing", letting occasionally the luff of the sail flapping. Due to the unsteadiness of the spinnaker itself, maintaining the luff ...
    • Aerodynamics of a highly cambered circular arc aerofoil : experimental investigations 
      Communication avec acte
      FLAY, Richard G.J.; PIARD, Arthur; ccBOT, Patrick (2017)
      While the aerodynamics of upwind sails are relatively well understood, flows past downwind sails are still very challenging. Indeed, downwind sails which can be considered as highly cambered thin wing profiles, are well ...
