    • Possibilistic Networks for Uncertainy Knowledge Processing in Student Diagnosis 

      Cocu, Adina ("Dunarea de Jos" University of Galati, 2006)
      In this paper, a possibilistic network implementation for uncertain knowledge modeling of the diagnostic process is proposed as a means to achieve student diagnosis in intelligent tutoring system. This approach is proposed ...
    • Power Conditioning System Topology For Grid Integration of Wind and Fuel Cell Energy 

      Găiceanu, Marian ("Dunarea de Jos" University of Galati, 2006)
      This paper shows the topology of the hybrid grid-connected power system and the performances of the front-end three-phase power inverter. The renewable sources of the hybrid power system consist of a solid oxide fuel cell ...
    • Some Rezults Concerning No-Storage Wide-Diesel Systems Control 

      Vlad, Ciprian; Cutululis, Nicolaos Antonio; Lefebvre, Julie; Ceangă, Emil ("Dunarea de Jos" University of Galati, 2006)
      This paper deal with the dynamics of an autonomous no storage wind-diesel system, comprising a diesel generator and a controlled wind system with a hypo/hyper synchronous cascade. The objective is to maximize the wind ...
    • Sonar Target Localization Based on Spike Coded Spectrograms 

      Peremans, Herbert; Fontaine, Bertrand ("Dunarea de Jos" University of Galati, 2006)
      Target location is coded into the pattern of spikes that run up the auditory nerve to the bat's brain. Realistic scenes containing multiple, closely spaced, reflectors give rise to complex echo signals consisting of multiple ...
    • Spectral Density Correction of a Signal at Frequency Variable Transformation 

      Nicolau, Viorel; Popa, Rustem; Miholca, Constantin ("Dunarea de Jos" University of Galati, 2006)
      The goal of this paper is to determine analytical expression for the spectral density function of a signal, affected by a known frequency transformation, which do not modify the process energy. Such transformations of ...
    • Stationary Frame Active Power Filter Control Based on Multiresolution Analysis 

      Culea, Mihai; Dumitriu, Teodor; Nichita, Mihai; Munteanu, Traian ("Dunarea de Jos" University of Galati, 2006)
      The paper presents an active power filter control method. The reference signal is generated in the stationary reference frame α-β using multiresolution analysis and the controllers used are P-resonant controllers, suitable ...
