    • On the behavior of EMD and MEMD in presence of symmetric alpha-stable noise 
      Article dans une revue avec comité de lecture
      KOMATY, Ali; ccBOUDRAA, Abdel-Ouahab; NOLAN, John; DARE-EMZIVAT, Delphine (Institute of Electrical and Electronics Engineers, 2015)
      EmpiricalMode Decomposition (EMD) and its extended versions such as Multivariate EMD (MEMD) are data-driven techniques that represent nonlinear and non-stationary data as a sum of a finite zero-mean AM-FM components referred ...
    • Upwind sail aerodynamics : A RANS numerical investigation validated with wind tunnel pressure measurements 
      Article dans une revue avec comité de lecture
      VIOLA, Ignazio; ccBOT, Patrick; RIOTTE, Matthieu (Elsevier, 2012)
      The aerodynamics of a sailing yacht with different sail trims are presented, derived from simulations performed using Computational Fluid Dynamics. A Reynolds-averaged Navier-Stokes approach was used to model sixteen sail ...
    • Dynamic Behaviour of a Flexible Yacht Sail Plan 
      Article dans une revue avec comité de lecture
      AUGIER, Benoit; ccBOT, Patrick; ccHAUVILLE, Frederic; DURAND, Mathieu (Elsevier, 2013)
      A numerical investigation of the dynamic Fluid Structure Interaction (FSI) of a yacht sail plan submitted to harmonic pitching is presented to address both issues of aerodynamic unsteadiness and structural deformation. The ...
    • An ontology for the generalization of the bathymetry on nautical charts 
      Communication avec acte
      YAN, Jingya; GUILBERT, Eric; SAUX, Eric (2014)
      On nautical charts, undersea features are portrayed by sets of soundings (depth points) and isobaths (depth contours) from which map readers can interpret landforms. Different techniques were developed for automatic soundings ...
    • Energy Storage Technologies for Smoothing Power Fluctuations in Marine Current Turbines 
      Communication avec acte
      ZHOU, Zhibin; BENBOUZID, Mohamed; CHARPENTIER, Jean-Frederic; ccSCUILLER, Franck; TANG, Tianhao (IEEE, 2012)
      With regard to marine renewable energies, significant electrical power can be extracted from marine tidal current. However, the power harnessed by a marine current turbine varies due to the periodicity of the tidal phenomenon ...
    • Power Limitation Control for a PMSG-Based Marine Current Turbine at High Tidal Speed and Strong Sea State 
      Communication avec acte
      ZHOU, Zhibin; ccSCUILLER, Franck; CHARPENTIER, Jean-Frederic; BENBOUZID, Mohamed; TANG, Tianhao (IEEE, 2013)
      This paper deals with the control strategies for a fixed-pitch marine current turbine (MCT) when the marine current speed exceeds the rated value corresponding to the rated power of generator and converter. Over-rated ...
    • A fault-tolerant multiphase permanent magnet generator for marine current turbine appications 
      Communication avec acte
      MEKRI, Fatiha; BENELGHALI, Seifeddine; BENBOUZID, Mohamed; CHARPENTIER, Jean-Frederic (IEEE, 2011)
      Tidal currents are being recognized as a resource for sustainable electrical power generation. However, the main challenge for marine current energy development is to minimize the operation costs and maintenance operations ...
