Spectral Density Correction of a Signal at Frequency Variable Transformation
("Dunarea de Jos" University of Galati, 2006)
The goal of this paper is to determine analytical expression for the spectral density function of a signal, affected by a known frequency transformation, which do not modify the process energy. Such transformations of ...
An ICA Based Method for Texture Recognition
("Dunarea de Jos" University of Galati, 2006)
The method proposed in this paper uses the Independent Component Analysis (ICA) for an application of unsupervised recognition of textures. The analysed texture is modelled by a weighted sum of almost statistically independent ...
Identification of the Non-Linear Systems Using Internal Recurrent Neural Networks
("Dunarea de Jos" University of Galati, 2006)
In the past years utilization of neural networks took a distinct ampleness because of the following properties: distributed representation of information, capacity of generalization in case of uncontained situation in ...
Frequency Content Oriented Modification of Quantization Matrix in DCT-Based Compression
("Dunarea de Jos" University of Galati, 2006)
In order to improve the compression rate for comparable values of error metrics, we propose a method to modify the standard quantization matrix used in JPEG, according to image frequency content. Unlike the method which ...
Three Fuzzy Reasoning Models as a Decisionsuport AID, to Find an Electrical Energy Tariff
("Dunarea de Jos" University of Galati, 2005)
This contribution is a laboratory-work developed as an example of approximate (fuzzy) reasoning for students, possible to be used as a decision – support to estimate an electrical energy (EE) price for consumers. The three ...
Computational experience in Solving Large Linear Matrix Equations for Automatic Control
("Dunarea de Jos" University of Galati, 2004)
State-of-the-art, uni-processor linear matrix equation solvers for automatic
control computations are investigated and compared for various problem sizes. Generalpurpose
SLICOT solvers are the most efficient ones for ...
Smart Home Prototype Remotely Controlled Through Internet
(Universitatea "Dunărea de Jos" din Galați, 2017)
The project aims to implement and use of an autonomous smart home
prototype system, to remotely monitor the important parameters like temperature,
atmospheric pressure, gas leaks, or burglary
On the Applicability of State-of-the-Art Fault Diagnosis Methodologies to Simple and Complex Systems
("Dunarea de Jos" University of Galati, 2010)
This paper performs an analysis on the applicability of state-of-the-art fault diagnosis methodologies to both simple and complex systems. Here, a complex system represents a system whose global behavior, which emerges ...
Active Power Compensator of the Current Harmonics Based on the Instantaneous Power Theory
("Dunarea de Jos" University of Galati, 2005)
The quality of the electrical current becomes a major concern. The proliferation of the power electronic converters, which are used extensively to control electrical apparatus in industrial and commercial applications (dc ...
Development of a Simulink Toolbox for Friction Control Design and Compensation
("Dunarea de Jos" University of Galati, 2005)
This paper focuses on the development of a MATLAB/Simulink® library for servo-systems with friction as a part of a new simulation platform dedicated to model, analysis and control design of friction. It is well known that ...
