A New Approach to E-Commerce Multi-Agent Systems
("Dunarea de Jos" University of Galati, 2007)
The negotiation process between two humans is an art. To capture the magic behind negotiation, a first step will be to build a model that incorporates human emotions and community emotional opinions. A model like this will ...
A Student Model in a Multi-Agent Intelligent System
("Dunarea de Jos" University of Galati, 2007)
The paper presents an intelligent tutoring system which provides a Student Model using the “overlay method”. The system’s tasks are distributed among the intelligent agents (software agents), each having clearly specified ...
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 ...
Automatic Modeling of the Linguistic Values for Database Fuzzy Querying
(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 ...
Knowledge Based Diagnostic System With Probabilistic Approach
("Dunarea de Jos" University of Galati, 2007)
This paper presents a knowledge learning diagnostic approach implemented in an educational system. Probabilistic inference is used here to diagnose knowledge understanding level and to reason about probable cause of learner’s ...
Omline industrial Proces Broacast and Control Based on IP and Serial Networks
("Dunarea de Jos" University of Galati, 2007)
The Internet network in conjunction with a strong security policy can be an
ideal online broadcast system for the industrial processes monitoring and control. Because
the distributed controllers are connected through ...
Control of a Multivariable Web Winding System
("Dunarea de Jos" University of Galati, 2007)
To guarantee a good productivity and a better quality of the industrial systems, it is necessary to know the evolution of its various parameters but also its operation mode. The main goal of this work is to carry out a ...
Thermal Processes Identification Using Virtual Instrumentation
("Dunarea de Jos" University of Galati, 2007)
In this paper the experimental identification problem of thermal processes is presented, in order to establish their mathematical models which permit the adoption of the automation solutions, respectively the specification ...
The Optimal Control for D.C. Position Drive System
("Dunarea de Jos" University of Galati, 2007)
A position drive system with D.C. motor is operated using conventional position, speed and current controls. These controls provide a good dynamic and steady-state behaviour, but they do not take in consideration the ...
Buck Supplies Outiput Voltage Ripple Reduction Using Fuzzy Control
("Dunarea de Jos" University of Galati, 2007)
Using the PWM control for switching power supplies the peaks EMI noise appear at the switching frequency and its harmonics. Using randomize or chaotic PWM control techniques in these systems the power spectrum is spread ...
