    • Comparison of PMSG and DFIG for Marine Current Turbine Applications 
      Communication avec acte
      BENELGHALI, Seifeddine; CHARPENTIER, Jean-Frederic; BENBOUZID, Mohamed (IEEE, 2010)
      Emerging technologies for marine current turbine are mainly relevant to works that have been carried out on wind turbines and ship propellers. It is then obvious that many electric generator topologies could be used for ...
    • Application of Flow Battery in Marine Current Turbine System for Daily Power Management 
      Communication avec acte
      ZHOU, Zhibin; CHARPENTIER, Jean-Frederic; TANG, Tianhao; ccSCUILLER, Franck; BENBOUZID, Mohamed (IEEE, 2014)
      Predictable tidal current resources make marine current turbine (MCT) generation system highly attractive as an electricity supply source for coastal areas and remote islands. However, the tidal speed varies greatly due ...
    • Bearing Fault Detection in DFIG-Based Wind Turbines Using the First Intrinsic Mode Function 
      Communication avec acte
      AMIRAT, Yacine; CHOQUEUSE, Vincent; CHARPENTIER, Jean-Frederic; BENBOUZID, Mohamed (IEEE, 2010)
      Wind energy conversion systems have become a focal point in the research of renewable energy sources. In order to make the DFIG-based wind turbines so competitive as the classical electric power stations it is important ...
    • Multicomponent AM-FM signals analysis based on EMD-B-splines ESA 
      Article dans une revue avec comité de lecture
      BOUCHIKHI, Abdelkhalek; ccBOUDRAA, Abdel-Ouahab (Elsevier, 2012)
      In this paper a signal analysis framework for estimating time-varying amplitude and frequency functions of multicomponent amplitude and frequency modulated (AM–FM) signals is introduced. This framework is based on local ...
    • Voiced speech enhancement based on adaptive filtering of selected intrinsic mode functions 
      Article dans une revue avec comité de lecture
      KHALDI, Kais; TURKI, Monia; ccBOUDRAA, Abdel-Ouahab (World Scientific, 2010)
      In this paper a new method for voiced speech enhancement combining the Empirical Mode Decomposition (EMD) and the Adaptive Center Weighted Average (ACWA) filter is introduced. Noisy signal is decomposed adaptively into ...
    • 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 ...
    • On the behavior of EMD and MEMD in presence of symmetric alpha-stable noise 
      Article dans une revue avec comité de lecture
      KOMATY, Ali; NOLAN, John; DARE-EMZIVAT, Delphine; ccBOUDRAA, Abdel-Ouahab (Institute of Electrical and Electronics Engineers, 2015)
      EmpiricalMode Decomposition (EMD) and its extended versions such as Multivariate EMD (MEMD) are data-driven techniques that represent nonlinear and non-stationary data as a sum of a finite zero-mean AM-FM components referred ...
