    • Performance Improvement of a Darrieus Tidal Turbine with Active Variable Pitch 
      Article dans une revue avec comité de lecture
      DELAFIN, Pierre-Luc; DENISET, François; ccHAUVILLE, Frederic (MDPI AG, 2021)
      Vertical axis turbines, also called Darrieus turbines, present interesting characteristics for offshore wind and tidal applications but suffer from vibrations and a lower efficiency than the more conventional horizontal ...
    • Knowledge-Based Recommendation for On-Demand Mapping: Application to Nautical Charts 
      Article dans une revue avec comité de lecture
      KOTEICH, Bilal; ccSAUX, Eric; LADDADA, Wissame (MDPI AG, 2021)
      Maps have long been seen as a single cartographic product for different uses, with the user having to adapt their interpretation to his or her own needs. On-demand mapping reverses this paradigm in that it is the map that ...
    • Development of an Experimental Blade-controlled Cycloidal Propeller 
      Communication avec acte
      FASSE, Guillaume; GERMAIN, Gregory; BECKER, Florent; ccHAUVILLE, Frederic (AFM, 2019)
      As an interesting naval propulsion system, this paper presents the development of an experimental cycloidal propeller. Cross-flow propellers are characterized by the rotation of several blades around a vertical axis ...
    • Development of a 6-DOF Dynamic Velocity Prediction Program for offshore racing yachts 
      Article dans une revue avec comité de lecture
      KERDRAON, Paul; HOREL, Boris; LETOURNEUR, Adrien; LE TOUZÉ, David; ccBOT, Patrick (Elsevier, 2020)
      Thanks to high lift-to-drag ratios, hydrofoils are of great interest for high-speed vessels. Modern sailing yachts fitted with foils have thus reached impressively high speeds on the water. But this hydrodynamic efficiency ...
    • Numerical study of a sinusoidal transverse propeller 
      Communication avec acte
      FASSE, Guillaume; CURUTCHET, Arnaud; PAILLARD, Benoît; ccCOUTIER-DELGOSHA, Olivier; ccHAUVILLE, Frederic; ccBAYEUL-LAINÉ, Annie-Claude (2018)
      In order to obtain higher propulsion efficiency for marine transportation, the authors have numerically tested a novel trochoidal propeller using a sinusoidal blade pitch function. The main results presented here are the ...
    • Extracting Global Shipping Networks from Massive Historical Automatic Identification System Sensor Data: A Bottom-Up Approach 
      Article dans une revue avec comité de lecture
      WANG, Zhihuan; WANG, Yinhai; ccCLARAMUNT, Christophe (MDPI, 2019)
      The increasing availability of big Automatic Identification Systems (AIS) sensor data offers great opportunities to track ship activities and mine spatial-temporal patterns of ship traffic worldwide. This research proposes ...
    • Ontologies for Geospatial information: progress and challenges ahead 
      Article dans une revue avec comité de lecture
      ccCLARAMUNT, Christophe (JOSIS, 2020)
      Over the past 50 years or so the representation of spatial information within computerized systems has been widely addressed and developed in order to provide suitable data manipulation, analysis, and visualisation mechanisms. ...
