    • Preliminary Design of A Torus Type Axial Flux Generator for Direct-Driven Tidal Current Turbine 
      Communication avec acte
      JIN, Jing; CHARPENTIER, Jean-Frederic; TANG, Tianhao (IEEE, 2014)
      This paper focuses on the preliminary design of a TORUS type AFPM generators used in the MW graded tidal current application. Two different structures can be derived based on the orientation of the main flux. In this paper, ...
    • Fuzzy logic based energy management strategy for a fuel cell/battery/ultra-capacitor hybrid ship 
      Communication avec acte
      ZHU, Lisi; PENG, Dongkai; HAN, Jingang; WANG, Tianzhen; TANG, Tianhao; CHARPENTIER, Jean-Frederic (IEEE, 2014)
      In this paper, energy management strategy based on fuzzy logic is proposed for a fuel cell hybrid ship, combining proton exchange membrane fuel cell (PEMFC), battery and ultra-capacitor (UC). This hybrid system aims to ...
    • On the Uncertainty of CFD in Sail Aerodynamics 
      Article dans une revue avec comité de lecture
      VIOLA, Ignazio Maria; RIOTTE, Matthieu; ccBOT, Patrick (Wiley, 2013)
      A verification and validation procedure for yacht sail aerodynamics is presented. Guidelines and an example of application are provided. The grid uncertainty for the aerodynamic lift, drag and pressure distributions for ...
    • A Modeling Approach for the Extraction of Semantic Information from a Maritime Corpus 
      Communication avec acte
      TSATCHA, Dieudonné; ccCLARAMUNT, Christophe; ccSAUX, Eric (Springer Berlin Heidelberg, 2013)
      This paper introduces an algorithm for retrieving semantic information from a maritime corpus. The method is based on Natural Language Processing (NPL) and combines a segmentation of large documents with principles of a ...
    • A Global Approach for the Design of a Rim- Driven Marine Turbine Generator for Sail Boat 
      Communication avec acte
      DROUEN, Laurent; CHARPENTIER, Jean-Frederic; ccSEMAIL, Eric; ccSEMAIL, Eric; ccCLENET, Stephane (IEEE, 2012)
      Development of new ways to provide clean onboard electric energy is a key feature for the sailing boat industry and sail race teams. This is why marine turbines (MT), are considered to provide onboard energy. These turbines ...
    • State of the Art of Fuel Cells for Ship Applications 
      Communication avec acte
      HAN, Jingang; CHARPENTIER, Jean-Frederic; TANG, Tianhao (IEEE, 2012)
      Fuel cells promise to be far more efficient, produce lower or zero emissions, and operate cleaner than conventional internal-combustion engine and gas turbine. They are already used for transportation application (buses, ...
    • A Visibility and Spatial Constraint-Based Approach for Geopositioning 
      Communication avec acte
      LE YAOUANC, Jean-Marie; ccCLARAMUNT, Christophe; ccSAUX, Eric (Springer-Verlag, 2010)
      Over the past decade, automated systems dedicated to geopositioning have been the object of considerable development. Despite the success of these systems for many applications, they cannot be directly applied to qualitative ...
