Studiu teoretic şi experimental asupra deplasării navelor cu pernă de aer
(Universitatea "Dunărea de Jos" din Galaţi, 1977)La deplasarea unei nave în apă şi aer, întregul ei corp este supus unor reacţiuni hidro şi aerodinamice. Aceste reacţiuni, care sunt forţe de suprafaţă, se compun din forţe de presiune, normale la suprafaţa corpului şi ... 
A Comparative Study Above Two SelfTuning Controllers With Aplication To The Control Of Synchronous Generator Excitation System
("Dunarea de Jos" University of Galati, 2000)This paper presents two selftuning control structures synthesized through the minimization of two criterion functions. It is described the computation methodology of the control laws, both being particularized for the ... 
Properties Of Potential Function Based Clustering Algorithms
("Dunarea de Jos" University of Galati, 2000)The clustering algorithms based on potential functions are capable of clustering a set of data, making no implicit assumptions on the cluster shapes and without knowing in advance the number of clusters. They are ... 
Some results on the modelling of TSS manufactiring lines
("Dunarea de Jos" University of Galati, 2000)This paper deals with the modelling of a particular class of manufacturing lines, governed by a decentralised control strategy so that they balance themselves. Such lines are known as “bucket brigades” and also as “TSS ... 
Modular neurofuzzy networks: sollutions for explicit and implicit knowledge integration
("Dunarea de Jos" University of Galati, 2000)In this paper we propose a unified approach for integrating implicit and explicit knowledge in neurosymbolic systems as a combination of neural and neurofuzzy modules. In the developed hybrid system, training data set ... 
Gis Components: an Overview of the Software Format Approaches
("Dunarea de Jos" University of Galati, 2000)The paper proposes a softwarel multimedia point of view of the resources and fi1e formats used in GIS applications. An overview of the most known software approaches for GIS data management and components is proposed in ... 
A Hybrid Aproach to Dynamic Course Generation on the WWW
("Dunarea de Jos" University of Galati, 2000)In recent years, hypermedia has been grown in interest in advanced research on teaching and learning. Futhermore, the extension of hypermedia toward intelligent hypermedia comes more than obviously to meet specific ... 
Secure Analog Data Transmission Based on Rössler Chaotic System Behavior
("Dunarea de Jos" University of Galati, 2000)This paper describes a new methodology for increasing the security of analog data transmission based on a mixture of the original analog signal with one of the state variables of Rössler chaotic system. The method is ... 
On Process Modelling Using Physical Oriented and Phenomena Based Principles
("Dunarea de Jos" University of Galati, 2000)This work presents a modelling framework based on phenomena description of the process. The approach is taken to easy understand and construct process model in heterogeneous possible distributed modelling and simulation ... 
On Phenomena Based Metamodelling  A Process System Engineering Point Of View
("Dunarea de Jos" University of Galati, 2000)This work is looking to methodological aspects of process modelling. The point of view is more from Process System Engineering (PSE) in order to develop formal and generic techniques for process modelling, and to use ... 
Finding Exception for Association Rules Via SQL Queries
("Dunarea de Jos" University Galati, 2000)Finding association rules is mainly based on generating larger and larger frequent set candidates, starting from frequent attributes in the database. The frequent sets can be organised as a part of a lattice of concepts ... 
The Application of Euler – Lagrange Method of Optimization for Electromechanical Motion Control
("Dunarea de Jos" University of Galati, 2000)Industrial and nonindustrial 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 ... 
On the harmonics reduction using wavelet based signal processing
("Dunarea de Jos" University of Galati, 2000)This paper presents a method for calculating the reference currents needed for the command of an active filter. By using the Discrete Wavelet Transform (DWT) the highfrequency components of the currents are eliminated. ... 
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 ... 
The Textual Idea and its Relationship to discourse structure
("Dunarea de Jos" University of Galati, 2000)The textual idea could be characterized through a series of either detailing the current form of idea or continuing a previous form of it. Every element of the series has associated a span of the given text that carries ... 
Tempoaspectualitate contrastivă
(2000)Lucrarea “Valențe ale timpurilor verbale în discurs” (în engleză și română) a fost elaborată avânduse în vedere, pe de o parte, un scop teoretic, iar pe de alta, unul practic. Obiectivul teoretic este acela de a oferi o ... 
Neural Network Schemes in Cartesian Space Control of Robot Manipulators
("Dunarea de Jos" University of Galati, 2001)In this paper we are studying the Cartesian space robot manipulator control problem by using Neural Networks (NN). Although NN compensation for model uncertainties has been traditionally carried out by modifying the joint ... 
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 (SDE) to suppress error propagation. In its first section, the paper presents the principle of the ... 
On a TakagiSugeno Fuzzy Controller with NonHomogenous Dynamics
