    • FSI Investigation on Stability of Downwind Sails with an Automatic Dynamic Trimming 
      Communication avec acte
      DURAND, Mathieu; LOTHODE, Corentin; ccHAUVILLE, Frederic; LEROYER, Alban; VISONNEAU, Michel; FLOCH, Ronan; GUILLAUME, Laurent (Ecole Navale, 2013)
      Gennakers are lightweight and flexible sails, used for downwind sailing configurations. Qualities sought for this kind of sail are propulsive force and dynamic stability. To simulate accurately the flow around such a sail, ...
    • A classification approach to efficient global optimization in presence of non-computable domains 
      Article dans une revue avec comité de lecture
      SACHER, Matthieu; DUVIGNEAU, Régis; LE MAÎTRE, Olivier; DURAND, Mathieu; BERRINI, Elisa; ccHAUVILLE, Frederic; ccASTOLFI, Jacques Andre (Springer Verlag (Germany), 2018)
      Gaussian-Process based optimization methods have become very popular in recent years for the global optimization of complex systems with high computational costs. These methods rely on the sequential construction of a ...
    • Dynamic measurements of pressures, sail shape and forces on a full-scale spinnaker 
      Communication avec acte
      DEPARDAY, Julien; ccBOT, Patrick; ccHAUVILLE, Frederic; MOTTA, Dario; LE PELLEY, David; FLAY, Richard G.J. (2014)
      This work presents a full-scale experimental study on a sailing yacht in downwind conditions with simultaneous time-resolved measurements of pressures, sail shape and loads. Those on-water experiments on a J/80 class yacht ...
    • Fictive motion extraction and classification 
      Article dans une revue avec comité de lecture
      EGOROVA, Ekaterina; MONCLA, Ludovic; GAIO, Mauro; ccCLARAMUNT, Christophe; PURVES, Ross (Taylor & Francis, 2018)
      Fictive motion (e.g. ‘The highway runs along the coast’) is a pervasive phenomenon in language that can imply both a static and a moving observer. In a corpus of alpine narratives, it is used in three types of spatial ...
    • Passive stochastic matched filter for Antarctic blue whale call detection 
      Article dans une revue avec comité de lecture
      BOUFFAUT, Léa; DRÉO, Richard; LABAT, Valérie; ccBOUDRAA, Abdel-Ouahab; BARRUOL, Guilhem (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 ...
    • Improving SIEM for Critical SCADA Water Infrastructures Using Machine Learning 
      Ouvrage scientifique
      HINDY, Hanan; ccBROSSET, David; BAYNE, Ethan; SEEAM, Amar; BELLEKENS, Xavier (Springer International Publishing, 2019)
      Network Control Systems (NAC) have been used in many industrial processes. They aim to reduce the human factor burden and efficiently handle the complex process and communication of those systems. Supervisory control and ...
    • Experimental analysis of a strong fluid–structure interaction on a soft membrane — Application to the flapping of a yacht downwind sail 
      Article dans une revue avec comité de lecture
      DEPARDAY, Julien; AUGIER, Benoit; ccBOT, Patrick (Elsevier, 2018)
      In the present study we investigate the flapping instability of a light, soft, highly cambered membrane subject to wind loading. An original in-situ experiment is developed where time-resolved pressures and forces are ...
