    • A Dempster-Shafer based approach to the detection of trajectory stop points 
      Article dans une revue avec comité de lecture
      HOSSEINPOOR, AMIN; ABBASPOUR, Rahim Ali; ccCLARAMUNT, Christophe (Elsevier, 2018)
      Nowadays, location-based data collected by GPS-equipped devices such as smartphones and cars are often stored as spatio-temporal sequences of points denoted as trajectories. The analysis of the large generated trajectory ...
    • A semantic model for human mobility in an urban region 
      Article dans une revue avec comité de lecture
      JIN, Meihan; ccCLARAMUNT, Christophe (2018)
      The continuous development and complexity of many modern cities offer many research challenges for urban scientists searching for a better understanding of mobility patterns that happen in space and time. Today, very large ...
    • An integrated Methodology for the Study of Spatial Data Infrastructures Use: the Case of Coastal Stakeholders in France 
      Article dans une revue avec comité de lecture
      GEORIS CRESEVEAU, Jade; GOURMELON, Françoise; ccCLARAMUNT, Christophe (Taylor & Francis, 2018)
      Nowadays the continuous development of Spatial Data Infrastructures provides a favorable context for environmental management. But in fact, the real contribution of SDIs depends on the answers they provide to their users. ...
    • Classification des Signaux sur Graphes par Mesures Spectrales Algébriques 
      Communication avec acte
      BAY-AHMED, Hadj-Ahmed; ccBOUDRAA, Abdel-Ouahab; DARE-EMZIVAT, Delphine; PREAUX, Yves (2017)
      La notion de mesure de similarité est très importante dans de nombreux domaines tels que l’apprentissage statistique, la fouille de données ou les sciences cognitives. Dans cet article, nous nous intéressons à la similarité ...
    • Flexible hydrofoil optimization for the 35th America's cup with constrained ego method 
      Communication avec acte
      SACHER, Matthieu; DURAND, Mathieu; BERRINI, Elisa; DUVIGNEAU, Régis; LE MAITRE, Olivier; ccHAUVILLE, Frederic (2017)
      This paper investigates the use of constrained surrogate models to solve the multi-design optimization problem of a flexible hydrofoil. The surrogate-based optimization (EGO) substitutes the complex objective function of ...
    • Graph Signals Classification Using Total Variation and Graph Energy Informations 
      Communication avec acte
      BAY-AHMED, Hadj-Ahmed; DARE-EMZIVAT, Delphine; ccBOUDRAA, Abdel-Ouahab (2017)
      In this work, we consider the problem of graph signals classification. We investigate the relevance of two attributes, namely the total variation (TV) and the graph energy (GE) for graph signals classification. The TV is ...
    • Speedometer Fault Detection and GNSS Fusion using Kalman Filters 
      Communication avec acte
      KERHASCOET, Hugo; LAURENT, Johann; SENN, Eric; ccHAUVILLE, Frederic (2016)
      Navigation systems used in racing boats require sensors to be more and more sophisticated in order to obtain accurate information in real time. To meet the need for accuracy of the surface speed measurement, the mechanical ...
