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 ... -
Arhitectura of a computer based instructional system
("Dunarea de Jos" University of Galati, 2000)The paper describes the architecture of a tutorial system that can be used at various engineering graduate and postgraduate courses. The tutorial is using Internetstyle WWW services to provide access to the teaching ... -
Artifacts Removing in Ultrasonic Images by Fusion Processes
("Dunarea de Jos" University of Galati, 2013)Allmost airborne ultrasonic images used in robotics have artefacts and distorstions, when comparing real objects with those presented in ultrasonic images. The differences between reral and reference images have various ... -
Aspects Regarding the Neuro-Adaptive Control Structura Proprieties. Application to the Nonline Pneumatic Servo System Benchmark
("Dunarea de Jos" Universsity of Galati, 2006)Generally, control techniques based on multilayer neural networks are used especially in the case of non-linear process and less in case of linear process, because classical control techniques are good enough and relatively ... -
Automatic Modeling of the Linguistic Values for Database Fuzzy Querying
("Dunare de Jos" University of Galati, 2007)In order to evaluate vague queries, each linguistic term is considered according to its fuzzy model. Usually, the linguistic terms are defined as fuzzy sets, during a classical knowledge acquisition off-line process. But ... -
