The Influence of Electric Transformers' Specific Parameters Modification on Power Distributions and on Technological Appropriate Consumption (TAC) Within the Energetic System
(The Annals of "Dunarea de Jos" University of Galati, 2005)
The paper deals with a comparative analysis – using DINIS(E) programming environment – of the way electric transformers' specific variables (Iron losses, the parameters of the equivalent scheme, the level of primary power ...
A Survey Text Clustering Techniques Used for Web Mining
("Dunarea de Jos" of Galati, 2005)
This paper contains an overview of basic formulations and approaches to clustering. Then it presents two important clustering paradigms: a bottom-up agglomerative technique, which collects similar documents into larger and ...
Fuzzy Queries in Romanian Language. An Intelligent Interface
("Dunarea de Jos" University of Galati, 2005)
The most accessible interfaces querying databases must be so intelligent, able to understand natural language expressions and including vague terms in selection criteria. The paper proposes a general architecture for a ...
Classification Process in a Text Document Recommender System
("Dunarea de Jos" University of Galati, 2005)
This paper presents the classification process in a recommender system used for textual documents taken especially from web. The system uses in the classification process a combination of content filters, event filters and ...
Feedback Linearization Control of Wind Power Systems
("Dunarea de Jos" University of Galati, 2004)
This paper focuses on the development of a feedback linearization control for a variable speed fixed pitch wind turbine driving a permanent magnet synchronous generator. The power system is considered to operate on an ...
The Distribution of the Electricfield and of the Current Density in Casa of Electrocorrosion Countermeasures Using the Sacrifice Anodes Technique
("Dunarea de Jos" University of Galati, 2005)
An electric field oriented from sea water towards the ship, can develop an extraction work. The corrosion process was thus diminished, by a change in the ship’s hull mass, due to a continuous tore of the material from its ...
Modeling and Speed Control of Induction Motor Drives Using Neural Networks
("Dunarea de Jos" University of Galati, 2010)
Speed control of induction motor drives using neural networks is presented.
The mathematical model of single phase induction motor is developed. A new simulink
model for a neural network-controlled bidirectional chopper ...
Simulation Results of Closed Loop Controlled Interline Power Flow Controller System
("Dunarea de Jos" University of Galati, 2010)
The Interline Power Flow Controller (IPFC) is the latest generation of Flexible
AC Transmission Systems (FACTS) devices which can be used to control power flows
of multiple transmission lines. A dispatch strategy is ...
Fea Based Axial Flux Permanent Magnet Linear Oscillating Motor
("Dunarea de Jos" University of Galati, 2010)
In this paper the development, finite element analysis(FEA) and electronic
control of an axial flux permanent magnet linear oscillating motor (PMLOM) suitable
for short strokes is described. The forces for aluminium mover ...
Digital Simulation of Closed Loop ZVS-ZCS Bidirectional DC-DC Converter for Fuel Celland Battery Application
("Dunarea de Jos" University of Galati, 2010)
A closed loop ZVS-ZCS bidirectional dc-dc converter is modeled and
appropriate digital simulations are provided. With the ZVS-ZCS concept, the MATLAB
simulation results of application to a fuel cell and battery application ...
