    • A Geometric Framework for Detection of Critical Points in a Trajectory Using Convex Hulls 
      Article dans une revue avec comité de lecture
      HOSSEINPOOR MILAGHARDAN, Amin; ABBASPOUR, Rahim Ali; ccCLARAMUNT, Christophe (MDPI, 2018)
      Large volumes of trajectory-based data require development of appropriate data manipulation mechanisms that will offer efficient computational solutions. In particular, identification of meaningful geometric points of such ...
    • A Spatio-Temporal Entropy-based Framework for the Detection of Trajectories Similarity 
      Article dans une revue avec comité de lecture
      HOSSEINPOOR MILAGHARDAN, Amin; ABBASPOUR, Rahim Ali; ccCLARAMUNT, Christophe (MDPI, 2018)
      The rapid proliferation of sensors and big data repositories offer many new opportunities for data science. Among many application domains, the analysis of large trajectory datasets generated from people’s movements at the ...
    • Fluid Structure Interaction of Yacht Sails in the Unsteady Regime 
      Chapitre d'ouvrage scientifique
      AUGIER, Benoit; ccBOT, Patrick; ccHAUVILLE, Frederic; DURAND, Mathieu (Editions de l'Ecole Polytechnique, 2013)
      The dynamic Fluid Structure Interaction (FSI) of yacht sails submitted to a harmonic pitching motion is numerically investigated to address both issues of aerodynamic unsteadiness and structural deformation. The model ...
    • A Survey of Modelling Trends in Temporal GIS 
      Article dans une revue avec comité de lecture
      SIABATO, Willington; ccCLARAMUNT, Christophe; ILARRI, Sergio; MANSO-CALLEJO, Miguel Angel (Association for Computing Machinery, 2018)
      The main achievements of spatio-temporal modelling in the field of Geographic Information Science that spans over the past three decades are surveyed. This article offers an overview of: (i) the origins and history of ...
    • Wind tunnel investigation of dynamic trimming on upwind sail aerodynamics 
      Article dans une revue avec comité de lecture
      AUBIN, Nicolas; AUGIER, Benoit; ccBOT, Patrick; ccHAUVILLE, Frederic; SACHER, Matthieu; FLAY, Richard G.J. (The Society of Naval Architects and Marine Engineers, 2017)
      An experiment was performed in the Yacht Research Unit’s Twisted Flow Wind Tunnel (University of Auckland) to test the effect of dynamic trimming on three IMOCA 60 inspired mainsail models in an upwind ( AW = 60°) unheeled ...
    • Modal Analysis of Pressures on a Full-Scale Spinnaker 
      Article dans une revue avec comité de lecture
      DEPARDAY, Julien; ccBOT, Patrick; ccHAUVILLE, Frederic; AUGIER, Benoit; RABAUD, Marc; MOTTA, Dario; LE PELLEY, David (The Society of Naval Architects and Marine Engineers, 2017)
      While sailing offwind, the trimmer typically adjusts the downwind sail “on the verge of luffing”, occasionally letting the luff of the sail flap. Due to the unsteadiness of the spinnaker itself, maintaining the luff on the ...
    • The influence of aeration and compressibility on slamming loads during cone water entry 
      Article dans une revue avec comité de lecture
      ELHIMER, Mehdi; JACQUES, Nicolas; EL MALKI ALAOUI, Aboulghit; GABILLET, Céline (Elsevier, 2017)
      The problem of the impact between a rigid body and a gas-liquid mixture is relevant to various engineering applications, including the design of breakwaters and LNG containers. In the present study, the specific problem ...
