  • Selişteanu, Dan; Ionete, Cosmin; Petre, Emil ("Dunarea de Jos" University of Galati, 2001)
    The paper presents on-line estimation strategies for bioprocesses, which are characterized by strongly nonlinear dynamics. A general form for the state observers is analysed and the exponential observability of bioprocesses ...
  • Cernega, Daniela Cristina; Mînzu, Viorel ("Dunarea de Jos" University of Galati, 2001)
    This paper proposes a control problem statement in the framework of supervisory control technique for the assembly workstations. A desired behaviour of an assembly workstation is analysed. The behaviour of such a workstation ...
  • Aiordăchioaie, Dorel ("Dunarea de Jos" University of Galati, 2001)
    The paper is looking to the dynamic feature of the meta-models of the process modelling process, the time. Some principles are considered and discussed as main dimensions of any modelling activity: the compatibility of ...
  • Ionete, Cosmin; Petre, Emil; Selişteanu, Dan ("Dunarea de Jos" University of Galati, 2001)
    The paper presents a robust control design strategy for bioprocesses, which are characterized by strongly nonlinear dynamics. More precisely, we present the H2 methodology in order to compute the controller for a recycle ...

    The paper describes the internal architecture of an Intelligent Tutoring System, CSTutor. The architectural design of the tutorial system was developed in a collaborative work at the Department of Computer Science of the ...
  • Oltean, Virginia Ecaterina; Cârstoiu, Dorian ("Dunarea de Jos" University of Galati, 2001)
    Hybrid systems have received a lot of attention in the past decade and a number of different models have been proposed in order to establish mathematical framework that is able to handle both continuous and discrete ...
  • Neagu, Ciprian-Daniel; Neagu, Daniela; Georgescu, Lucian; Palade, Vasile ('Dunarea de Jos" University of Galati, 2001)
    This work illustrates the necessity of an Artificial Intelligence (AI)-based approach of air quality in urban and industrial areas. Some related results of Artificial Neural Networks (ANNs) and Fuzzy Logic (FL) for ...
  • Judele, Stelian; Solea, Răzvan; Dugan, Viorel ("Dunarea de Jos" University of Galati, 2001)
    The goal of this paper is to analyze the limitations of a static VAr compensator (SVC) with switched capacitor, when this operate as an active filter. The limitations considered and studied by simulation are in the zone ...
  • Caraman, Sergiu; Frangu, Laurenţiu; Turtoi, Maria ("Dunarea de Jos" University of Galati, 2001)
    The paper deals with the development of a software system (BIOCALC) for the modelling, identification and simulation of the biotechnological processes. BIOCALC is based on the algorithm developed by George Bastin and ...
  • Turtoi, Maria; Hopulele, Traian; Caraman, Sergiu ("Dunarea de Jos" University of Galati, 2001)
    The surface response methodology is used to verify predicted models and to adapt them on particular conditions of growth. The effect of solvent addition during the linear cell growth on the enhancement of biodegradation ...
  • Popa, Ioan Şerban; Popescu, Mihai Octavian; Popescu, Claudia ("Dunarea de Jos" University of Galati, 2002)
    An energetic description of the electric transport urban system ASTRAIK 415T is proposed according to a specific formalism. This is used to simulate the trolleybus system, equipped with a chopper and a direct current ...
  • Fetecău, Grigore; Iordache, Viorel-Eugen; Hug, Eric (2002)
    The paper synthetically presents the results obtained over the degradation of magnetic properties of soft ferromagnetic sheets Fe-3%Si NO required mechanically in plastic deformation area. Chronologically, the evolution ...
  • Alexandru, Decebal; Enache, Monica-Adela; Marinas, Paul ("Dunarea de Jos" University of Galati, 2002)
    The induction motors supply by converters leads to a distorted regime accompanied by some parasite torques and some supplementary losses. These aspects are emphasized further on because their quantitative determinations ...
  • Imecs, Maria; Incze I., Ioan; Szabó, Csaba ("Dunarea de Jos" University of Galati, 2002)
    The paper deals with rotor-field-oriented vector control structures for the induction motor drives fed by the so-called tandem frequency converter. It is composed of two different types of DC-link converters connected ...
  • Bivol, Ion; Roşu, Emil; Ceangă, Emil ("Dunarea de Jos" University of Galati, 2002)
    The development in continuous casting process has been strongly dominated by the demands of quality improvement and reduced costs for steel products in recent years. To achieve these goals consideration has been given ...
