    • Analysis and Design of Embedded Controlled Parallel Resonant Converter 

      Chandrasekhar, P.; Rama Reddy, S. ("Dunarea de Jos" University of Galati, 2009)
      Microcontroller based constant frequency controlled full bridge LC parallel resonant converter is presented in this paper for electrolyser application. An electrolyser is a part of renewable energy system which generates ...
    • Spatio-Temporal Dynamics in Celular Neural Networks 

      Goras, Liviu ("Dunarea de Jos" University of Galaţi, 2009)
      Analog Parallel Architectures like Cellular Neural Networks (CNN’s) have been thoroughly studied not only for their potential in high-speed image processing applications but also for their rich and exciting spatio-temporal ...
    • Power Estimation of Pipeline FFT Processors 

      Talebiyan, S. Reza; Hosseini-Khayat, Saied ("Dunarea de Jos" University of Galati, 2009)
      Pipeline FFT processors are used in mobile communication systems and in particular in OFDM-based systems. This paper presents a method for power analysis of pipeline FFT processors. This method applies to various ...
    • The Phase Spectra Based Feature for Robust Speech Recognition 

      Ali, Abbasian; Hosslen, Marvi ("Dunarea de Jos" University of Galati, 2009)
      Speech recognition in adverse environment is one of the major issue in automatic speech recognition nowadays. While most current speech recognition system show to be highly efficient for ideal environment but their ...
    • Channel Allocation Management Using Agents Technology 

      Sîrbu, Gabriel; Bogdan, Ion ("Dunarea de Jos" University of Galati, 2009)
      Channel allocation schemes are management techniques meant to solve the radio access problem in the telecommunications area. There are several known schemes namely: static, dynamic, hybrid and flexible channel allocation ...
    • Accurate Localization of Communicant Vehicles Using GPS and Vision System 

      Challita, G.; Mousset, S.; Nashashibi, F.; Bensrhair, A. ("Dunarea de Jos" University of Galati, 2009)
      The new generation of ADAS systems based on cooperation between vehicles can offer serious perspectives to the road security. The inter-vehicle cooperation is made possible thanks to the revolution in the wireless mobile ...
    • A Distortion Input Parameter in Image Denoising Algorithms with Wavelets 

      Gogu, Anista; Aiordăchioaie, Dorel ("Dunarea de Jos" University of Galati, 2009)
      The problem of image denoising based on wavelets is considered. The paper proposes an image denoising method by imposing a distortion input parameter instead of threshold. The method has two algorithms. The first one is ...
    • Active Power Filter with Indirect Control for Line-Frequency Controlled Rectifiers 

      Roşu, E.; Culea, M.; Dumitriu, T. ("Dunarea de Jos" University of Galati, 2009)
      Line-frequency controlled rectifiers have two major disadvantages: variable displacement power factor and high harmonic current fed to the power supply. If the power converter is large, e.g. for rolling mills drives, it ...
    • Proton Exchange Membrane Fuel Cell Modelling Using Moving Least Squares Technique 

      Tîrnovan, R.; Giurgea, S.; Miraoui, A. ("Dunarea de Jos", 2009)
      Proton exchange membrane fuel cell, with low polluting emissions, is a great alternative to replace the traditional electrical power sources for automotive applications or for small stationary consumers. This paper ...
    • Integrated Solid Oxide Fuel Cell Power System Characteristics Prediction 

      Gâlceanu, Marian; Orsello, Glanmichele ("Dunarea de Jos" University of Galati, 2009)
      The main objective of this paper is to deduce the specific characteristics of the CHP 100kWe Solid Oxide Fuel Cell (SOFC) Power System from the steady state experimental data. From the experimental data, the authors have ...
