    • Audio watermarking via EMD 
      Article dans une revue avec comité de lecture
      KHALDI, Kais; ccBOUDRAA, Abdel-Ouahab (Institute of Electrical and Electronics Engineers, 2013)
      In this paper a new adaptive audio watermarking algorithm based on Empirical Mode Decomposition (EMD) is introduced. The audio signal is divided into frames and each one is decomposed adaptively, by EMD, into intrinsic ...
    • Concepts, Modélisation et Commandes des Hydroliennes 
      Chapitre d'ouvrage scientifique
      ccBENBOUZID, Mohammed; ccASTOLFI, Jacques Andre; BACHA, Seddik; ccCHARPENTIER, Jean-Frederic; MACHMOUN, Mohamed; MAITRE, Thierry; ROYE, Daniel (Hermes Science Publications, 2011)
      Face au problème de la gestion des déchets nucléaire et aux émissions de gaz à effet de serre, les énergies renouvelables occupent une place avancée parmi les énergies d’avenir grâce à leur faible impact sur l’environnement ...
    • Psi_B-energy operator and cross-power spectral density 
      Article dans une revue avec comité de lecture
      ccBOUDRAA, Abdel-Ouahab; CHONAVEL, Thierry; CEXUS, Jean-Christophe (Elsevier, 2014)
      In this paper we consider the hermitian extension of the cross-Psi_B-energy operator that we will denote by Psi_H. In addition, cross energy terms are formalized through multivariate signals representation. We investigate ...
    • 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 ...
    • Induction machine bearing failures detection using stator current frequency spectral subtraction 
      Communication avec acte
      EL BOUCHIKHI, El Houssin; CHOQUEUSE, Vincent; BENBOUZID, Mohamed; CHARPENTIER, Jean-Frederic (IEEE, 2012)
      Abstract—Induction machines are widely used in industrial applications. Safety, reliability, efficiency and performance are major concerns that direct the research activity in the field of electrical machines. Though the ...
    • A Modeling Approach for the Extraction of Semantic Information from a Maritime Corpus 
      Communication avec acte
      TSATCHA, Dieudonné; ccSAUX, Eric; ccCLARAMUNT, Christophe (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 ...
    • Implications of Control Schemes for Electrical system design in tidal energy converters 
      Chapitre d'ouvrage scientifique
      BENELGHALI, Seifeddine; BENBOUZID, Mohamed; CHARPENTIER, Jean-Frederic (IET, 2013)
      The tidal current turbulences and the system parameter drift due to the system wear out can significantly influence the MCT dynamic performance. In this context, various control techniques, suitable to any particular MCT ...
