    • Minimizing the Error Tracking of Mobile Terminals by Kalman Filtering 

      Bogdan, Ion (2006)
      A method to track mobile terminals in a cellular communication network is presented. It uses the received field strength from the surrounding base stations. A subsequent Kalman filtering is used to minimize the tracking error.
    • Non-Conventional Method for Friction Compensation in DC Drive Position Tracking 

      Dumitriu, Teodor; Culea, Mihai; Nichita, Mihai; Munteanu, Traian ("Dunarea de Jos" University of Galati, 2006)
      Friction, especially its nonlinear components, may degrade the tracking performance of any servo drive systems. Focused on high precision positioning of DC electrical drive the paper proposes an easy method to compensate ...
    • A Novel Feature Extraction Method for Isolated Word Recognition Based on Nested Temporal Averaging 

      Dogaru, Radu; Costache, Gabriel Nicolae; Dumitru, Octavian; Gavat, Inge ("Dunarea de Jos" University of Galati, 2006)
      A novel preprocessing method is proposed. It has a reduced complexity and therefore is aimed to be used in low power, VLSI implemented, speech recognizers. Our algorithm extracts a feature vector made from up to 3 feature ...
    • On the Potential of Using Fractional-Order Systems to Model the Respiratory Impedance 

      Ionescu, Clara; De Keyser, Robin ("Dunarea de Jos" University of Galati, 2006)
      This contribution provides an analysis of the human respiratory system in frequency domain by means of estimating the respiratory impedance. Further on, analysis of several models for human respiratory impedance is done, ...
    • Optimal Coding for Qualitative Sources on Noiseless Channels 

      Munteanu, Valeriu; Tarniceriu, Daniela ("Dunarea de Jos" University of Galati, 2006)
      In this paper we perform the encoding for sources which are only qualitatively characterized, that is, each message the source delivers possesses a certain quality, expressed as cost, importance or utility. The proposed ...
    • 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 ...
