A Simple Load Power Estimator for Quasi-Direct AC-AC Converter System
("Dunarea de Jos" University of Galati, 2003)In this paper a simple load power estimator for the three-phase quasi-direct acac converter system is reported. Since the ac-ac converter control by means of pulsewidth modulation (PWM) is based on the power balance ... -
Vague Criteria Relational Database Queries
("Dunarea de Jos" University of Galati, 2003)The most accessible interfaces querying relational database should allow vague terms included in selection criteria. The gradual property stands for the simplest vague selection criterion, but more categories of vague ... -
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 ... -
Structure of Management Information in SNMP
(2003)In this article we present the Structure of Management Information from SNMP, for all three versions of SNMP, as well as the main differences between them. In the first part, two version of SNMP are presented: version ... -
The Influence of the Ship's Steering Machine Over Yan and Roll Motions
("Dunarea de Jos" University of Galati, 2003)The steering machine is a nonlinear system, with two important limitations: the maximum rudder angle and rudder rate. Therefore, the commands from yaw and rudder-roll control systems are modified and the expected effect ... -
The Parametric Identification of a Stationary Process
("Dunarea de Jos" University of Galati, 2003)In the problems of identification it is supposed that the process has at least one measurable input size and at least one measurable output size. The identification of a process has three stages: the obtaining of a ... -
A New Method of Gene Coding for Genetic Algorithm Designed for Parametric Optimization
("Dunarea de Jos" University of Galati, 2003)In a parametric optimization problem the genes code the real parameters of the fitness function. There are two coding techniques known under the names of: binary coded genes and real coded genes. The comparison between ... -
On Estimation of the Orientation of Mobele Robots Ising Turning Fuctions and Sonar Information
("Dunarea de Jos" University of Galati, 2003)SONAR systems are widely used by some artificial objects, e.g. robots, and by animals, e.g. bats, for navigation and pattern recognition. The objective of this paper is to present a solution on the estimation of the ... -
Building Similarity Maps of the Environment Using Sonar Information for the Navigation of Mobile Robots
("Dunarea de Jos" University of Galati, 2003)The objective of the work is to present a representation called similarity map based on some results in the evaluation of the SONAR system of a mobile robot. As environment a corner of our lab it is considered. Based on ... -
A Novel Parametric Model for the Human Respiratory System
("Dunarea de Jos" University of Galati, 2003)The purpose of this work is to present some recent results in an ongoing research project between Ghent University and Chess Medical Technology Company Belgium. The overall aim of the project is to provide a fast method ... -
The Disturbance Model in Based Predictive Control
("Dunarea de Jos" Univesity of Galati, 2003)Model Based Predictive Control (MBPC) is a control methodology which uses a process model on-line in the control computer; this model is used for calculating output predictions and optimizing control actions. The importance ... -
Flexible Joints Robotic Manipulator Control by Adaptive Gain Smooth Sliding Observer-Controller
("Dunarea de Jos" University of Galati, 2003)An adaptive gain sliding observer for uncertain parameter nonlinear systems together with an adaptive gain sliding controller is proposed in this paper. It considered nonlinear, SISO affine systems, with uncertainties ... -
Automatic Processing of Radar Images for Electronic River Chart Generation in Ecdis Format
("Dunarea de Jos" University of Galati, 2003)Presenting the navigation environment in electronic format – ECDIS – triggers a major change of the classic method of cartography and raises up the need to approach a way of producing the charts in vector-like format. ... -
Decomposition Methods to Optimise the Structure and Parameters of Transfer line with Parallel and Sequential Machining
("Dunarea de Jos" University of Galati, 2003)The paper is devoted to a preliminary design problem of paced automatic transfer lines. At this design stage, the following decisions are to be made: the partitioning of the given set of operations into subsets performed ...
