Learning Bayesian Dependence Model for Student Modelling
("Dunarea de Jos" University of Galati, 2008)
Learning a Bayesian network from a numeric set of data is a challenging
task because of dual nature of learning process: initial need to learn network
structure, and then to find out the distribution probability tables. ...
Pid Self-Tuning Controllers Used in Different Structures of the Control Loops
("Dunarea de Jos" University of Galati, 2008)
The paper investigates the behavior of digital PID self-tuning controllers
(STC) in different structures of the control loops used in adaptive systems. In the two
phases of this type of systems which use a STC-PID, the ...
Mathematical Analysis of Uncertainty
("Dunarea de Jos" University of Galati, 2008)
Classical Logic showed early its insufficiencies for solving AI problems. The
introduction of Fuzzy Logic aims at this problem. There have been research in the
conventional Rough direction alone or in the Fuzzy direction ...
Modelling Inteligent Systems With Level Petri Nets
("Dunarea de Jos" University of Galati, 2008)
Level Petri Nets are formalism for modeling hierarchical multi-agent system.
They are a Petri nets extension, allowing tokens to be nets themselves. This paper is
inspired by two classes of level Petri nets: object Petri ...
Selection of the Diagnostic Hypotheses Through Fuzzy Decizion in Medical Diagnosis System
(The Annals of "Dunarea de Jos" University of Galati, 2008)
The paper presents an evaluation of the diagnostic hypotheses’ selection step
within the medical diagnosis hybrid system DiaMed. Medical diagnoses are described in
DiaMed through fuzzy decision functions that are used ...
Web User Profile Using XUL and Information Retrieval Techniques
("Dunarea de Jos" University of Galati, 2008)
This paper presents the importance of user profile in information retrieval,
information filtering and recommender systems using explicit and implicit feedback. A
Firefox extension (based on XUL) used for gathering data ...
Recommendation Process SRI Web Document Recommender System
("Dunarea de Jos" University of Galati, 2008)
This paper presents a recommender system for web documents (given as
bookmarks). The system uses for classification a combination of content, event and
collaborative filters and for recommendation a modified Pearson-r ...
An Algorithm for Thresholding in the Context of Signal Denoising with Wavelets
("Dunarea de Jos" University of Galati, 2008)
The problem of estimating a signal corrupted by additive noise has been of
interest to many researchers for practical as well as theoretical reasons. Wavelet based
methods have become increasingly popular, due to a number ...
Optimal Control Development System for Electrical Drives
("Dunarea de Jos" University of Galati, 2008)
In this paper the optimal electrical drive development system is presented. It
consists of both electrical drive types: DC and AC. In order to implement the optimal
control for AC drive system an Altivar 71 inverter, a ...
Estimation of Steel Solidified Layer Thickness, for Continuous Casting Control Purposes
(2008)
An important goal in continuous casting automation process rest in
establishing a proper casting speed being able to assure a compromise between machine
productivity and solidified skin cracking protection on the mould ...
