Active Power Filter with Indirect Control for Line-Frequency Controlled Rectifiers
("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 ... -
Adaptive Filter Used as a Dinamic Compensator in Automatic Gauge Control of Strip of Rolling Proceses
("Dunarea de Jos" University of Galati, 2010)The paper deals with a control structure of the strip thickness in a rolling mill of quarto type (AGC – Automatic Gauge Control). It performs two functions: the compensation of errors induced by unideal dynamics of the ... -
An ADCSP-Based Non-Monotonic Framework for Medical Diagnosis
("Dunarea de Jos" University of Galati, 2010)The ability to reason within a dynamical environment is of crucial importance in Artificial Intelligence. The present paper models nonmonotonic reasoning by means of a DCSP (Dynamic Constraint Satisfaction Problems) ... -
An Algorithm for Thresholding in the Context of Signal Denoising with Wavelets
("Dunarea de Jos" University of Galati, 2008)The problem of estimating a signal corrupted by additive noise has been of interest to many researchers for practical as well as theoretical reasons. Wavelet based methods have become increasingly popular, due to a number ... -
Algorithms for Wireless Channel Equalization with Joint Coding and Soft Decizion Feedback
("Dunarea de Jos" University of Galati, 2001)The paper proposes a new approach based on Joint Entropy Maximisation (JEM) using a soft decision feedback equalizer (S-DE) to suppress error propagation. In its first section, the paper presents the principle of the ... -
Analysis and Design of Embedded Controlled Parallel Resonant Converter
("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 ... -
Analysis and Experimental Verification of Series Resonant PFC DC to DC Converter
("Dunarea de Jos" University of Galati, 2010)The aim of this work is to simulate and implement Series Resonant PFC DC – DC converter using Matlab Simulink. The quality of power consumption in terms of power factor and electromagnetic interference (EMI) levels are ... -
Analysis of a Neuro-Fuzzy Approach of Air Pollution: Building a Case Study
('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 ... -
Analysis of Functional Stability of the Triphased Asynchronous Generator Used in Conversion Systems of a Eolian Energy Into Electric Energy
("Dunarea de Jos" University of Galati, 2003)This paper presents a study of the influence of the main perturbation agent over the functional stability of the triphased asynchronous generator (for the two alternative: with coiled and short circuit rotor), used for ... -
An Analysis of Regimes of Parallel Generators Operation in Wind Turbine System
(Universitatea "Dunărea de Jos" din Galaţi, 2011-07)The parallel connection of different types of AC generators, used as example in isolated sites, represents a difficult problem due to the different particularities of the that generators involved. This paper analyses the ... -
Aodv Backup Node Mechanism with QOS Enable Routing in Mobile AD-HOC Networks
(Universitatea "Dunărea de Jos" din Galați, 2017)To manage the intrinsic properties of MANETs, a backup path algorithm for quick reconnection during link failures, is proposed. Also, proposed model reduces current recovery time by improving reliability of network. ... -
The Application of Euler – Lagrange Method of Optimization for Electromechanical Motion Control
("Dunarea de Jos" University of Galati, 2000)Industrial and non-industrial processes such as production plans, robots, pumps, compressors, home applications, transportation of people and goods etc., require some kinds of motion control. The main functions of ... -
Applications of the Emergence in Cognitive Mas
("Dunarea de Jos" University of Galati, 2012)The emergence and self-organization have been extensively studied in Multi-Agent Systems comprising simple, ant-like agents. When it comes to human multi-agent systems, the inter-agent, and agent-environment interactions ... -
The Appoach for Optimization of Transmission Over Power Links Using the Thyristor-Controlled Series Compensation
(The Annals of "Dunarea de Jos" University of Galati, 2008)The energy transportation networks can be improved by multiplying or creating new lines. This is not always the case for various reasons. The series capacities controlled by SCRs (Silicon Controlled Rectifiers) represent ... -
