    • 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 ...

    • 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 ...

    • An ICA Based Method for Texture Recognition 

      Colţuc, Daniela; Fournel, Thierry; Becker, Jean-Marie; Boutant, Yann ("Dunarea de Jos" University of Galati, 2006)
      The method proposed in this paper uses the Independent Component Analysis (ICA) for an application of unsupervised recognition of textures. The analysed texture is modelled by a weighted sum of almost statistically independent ...

    • Identification of the Non-Linear Systems Using Internal Recurrent Neural Networks 

      Puşcaşu, Gheorghe; Codreş, Bogdan; Stancu, Alexandru ("Dunarea de Jos" University of Galati, 2006)
      In the past years utilization of neural networks took a distinct ampleness because of the following properties: distributed representation of information, capacity of generalization in case of uncontained situation in ...

    • Frequency Content Oriented Modification of Quantization Matrix in DCT-Based Compression 

      Tarniceriu, Daniela; Munteanu, Valeriu; Beldianu, Florin ("Dunarea de Jos" University of Galati, 2006)
      In order to improve the compression rate for comparable values of error metrics, we propose a method to modify the standard quantization matrix used in JPEG, according to image frequency content. Unlike the method which ...

    • A Critical Evaluation of Indian Government’s Strategies to Bridge Digital Divide 

      Bhatt, Nityesh (Universitas Galatiensis, 2006-01)
      Emergence of Information and Communication Technology (ICT) has been a landmark for India. In one way, this sunshine sector has been instrumental in the economic growth of country and has glorified its image in the whole ...

    • Methodology of diagnosing enterprise activity and techniques of diagnosis 

      Onica, Mihaela Cristina (Universitas Galatiensis, 2006-01)
      The diagnosing methodology, on one hand, should allow liberation of the main elements for elaboration of the survey and, besides that, for thorough research in case of abnormalities and, on the other hand, should neglect ...
