    • 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 ...
    • Débruitage fréquentiel de signaux par EMD 
      Communication avec acte
      KOMATY, Ali; DARE-EMZIVAT, Delphine; ccBOUDRAA, Abdel-Ouahab (2013)
      Dans cet article, nous proposons un nouveau schéma de débruitage des signaux basé sur la décomposition modale empirique associée à une analyse fréquentielle. Le principe de l’approche consiste à seuiller les modes extraits ...
    • Instantaneous frequency estimation of FM signals by Psi_B-energy operator 
      Article dans une revue avec comité de lecture
      ccBOUDRAA, Abdel-Ouahab (IET, 2011)
      Psi_B energy operator is an extension of the cross Teager-Kaiser energy operator which is an non-linear energy tracking operator to deal with complex signals and its usefulness for non-stationary signals analysis has been ...
    • Nonlinear disturbance evolution in a two-dimensional boundary layer along an elastic plate and induced radiated sound 
      Article dans une revue avec comité de lecture
      GOBERT, Marie-Laure; EHRENSTEIN, Uwe; ccASTOLFI, Jacques Andre; ccBOT, Patrick (Elsevier, 2010)
      The interaction between a boundary-layer flow and an elastic plate is addressed by direct numerical simulation, taking into account the full coupling between the fluid flow and the flexible wall. The convectively unstable ...
    • 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 ...
    • Cable length optimization for trawl fuel consumption reduction 
      Article dans une revue avec comité de lecture
      KHALED, Ramez; PRIOUR, Daniel; BILLARD, Jean-Yves (Elsevier, 2013)
      A numerical method for optimization of the cable lengths in trawls with respect to the ratio between the estimated trawl drag and the predicted catch efficiency is developed and applied. The trawl cables of interest are ...
    • Loop detection of mobile robots using interval analysis 
      Article dans une revue avec comité de lecture
      AUBRY, Clément; DESMARE, Rozenn; JAULIN, Luc (Elsevier, 2013)
      This paper proposes an original set-membership approach for loop detection of mobile robots in the situation where proprioceptive sensors only are available. To detect loops, the new concepts of the t-plane (which is a two ...
