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 a Nonlinear Pneumatic Servo System Using Modular Neural Networks
("Dunărea de Jos" University of Galati, 2010)Sometimes, in the case of highly nonlinear systems the traditional approaches of identification and control could be difficult to implement. In this case, a good alternative are the neural networks. In this paper a modular ... -
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 ... -
Immpact of Bandwidth for Various Services in Heterogeneous Network and Quality of Service Via Communication Technologies in Malaysian Higher Educational
("Dunarea de Jos" University of Galati, 2007)This study focuses on heterogeneous services and communication technologies for retrieving and sending information between students and lecturers in Malaysian higher educational institutes. It intends to investigate pattern ... -
Imperfect Data in Database Context. How are they Stored in Extended Relational Databases?
("Dunarea de Jos" University of Galati, 2002)Building a more accurate reality model requires taking into account imperfect information present in our knowledge and language. This paper presents several aspects of data imperfection in the database context and the ... -
Improving the Power Factor at Unbalanced Consumers
("Dunarea de Jos" University of Galati, 2010)Unbalanced consumers have led to power quality problems. It is therefore necessary to have on hand solutions and equipment capable of improving the power quality. This paper provides a comparison on improving the power ... -
Indirect Control of a Low Power Single-Phase Active Power Filter
("Dunarea de Jos" University of Galati, 2010)This paper deals with a low power, single phase active filter used to compensate nonlinear loads. The filter uses the indirect control method and it is based on a particular connection between filter, polluting load and ... -
Indirect Control of a Single-Phase Active Power Filter
("Dunarea de Jos" University of Galati, 2006)The control of shunt active power filters using PWM inverters consists in generating a reference by separating, using different methods, the harmonics to be eliminated. The methods used are time-consuming and need dedicated ... -
The Influence of Electric Transformers' Specific Parameters Modification on Power Distributions and on Technological Appropriate Consumption (TAC) Within the Energetic System
(The Annals of "Dunarea de Jos" University of Galati, 2005)The paper deals with a comparative analysis – using DINIS(E) programming environment – of the way electric transformers' specific variables (Iron losses, the parameters of the equivalent scheme, the level of primary power ... -
Influence of High Performance Voltage Converters Supply Upon the Induction Motors Behaviour
("Dunarea de Jos" University of Galati, 2002)The induction motors supply by converters leads to a distorted regime accompanied by some parasite torques and some supplementary losses. These aspects are emphasized further on because their quantitative determinations ... -
The Influence of Non-Homogenous Dielectric Material in the Waveguide Propagation Modes
("Dunarea de Jos" University of Galati, 2006)The aim of this paper is to indicate the equations of electromagnetic wave in homogenous and non-homogenous dielectric material, estabilising the bundary conditions and solves by FEM the equations of the electromagnetic ... -
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 ... -
Integrated Solid Oxide Fuel Cell Power System Characteristics Prediction
("Dunarea de Jos" University of Galati, 2009)The main objective of this paper is to deduce the specific characteristics of the CHP 100kWe Solid Oxide Fuel Cell (SOFC) Power System from the steady state experimental data. From the experimental data, the authors have ... -

("Dunarea de Jos" University of Galati, 2001)The paper describes the internal architecture of an Intelligent Tutoring System, CSTutor. The architectural design of the tutorial system was developed in a collaborative work at the Department of Computer Science of the ... -
Intelligent Software Agents for decizion Making in Enterprise
(Universitatea "Dunarea de Jos" of Galati, 2013)This paper will attempt to highlight the complexity of decision-making mechanisms as well as the interest of integrating the cognitive dimension into the simulation models, with a view to evaluate the impact of technological ... -
Invariance Properties of Time-Varying Linear Systems
("Dunarea de Jos" University of Galati, 2007)This paper formulates and proves two types of necessary and sufficient conditions for the characterization of positively (flow) invariant sets with respect to the state-space trajectories of the time-varying (non-autonomous) ... -
IT&C Solutions for Intelligent Transportation Systems
("Dunarea de Jos" University of Galati, 2013)Road traffic congestion has incredibly high social costs, due to unnecessary fuel consumption, environment pollution, wasted time, and increased risk of accidents. As the road infrastructure obviously grows slower than the ... -
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 ... -
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. ... -
Limitations of a Static VAr Compensator (SVC) with Switched Capacitor Operating as an Active Filter
("Dunarea de Jos" University of Galati, 2001)The goal of this paper is to analyze the limitations of a static VAr compensator (SVC) with switched capacitor, when this operate as an active filter. The limitations considered and studied by simulation are in the zone ...
