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 -
Software System for Generating, Identification and Simulation of the Biotechnological Processes Models
("Dunarea de Jos" University of Galati, 2001)The paper deals with the development of a software system (BIOCALC) for the modelling, identification and simulation of the biotechnological processes. BIOCALC is based on the algorithm developed by George Bastin and ... -
Some Considerations Regarding the Efficiency of the Electromechanical Motion
("Dunarea de Jos" University of Galati, 2002)Control techniques for servo drive which run at variable speed for prolonged time is developed on the base of minimum energy dissipation in a feed-forward structure. The optimal control laws are determinate using the ... -
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 ... -
Some Rezults Concerning No-Storage Wide-Diesel Systems Control
("Dunarea de Jos" University of Galati, 2006)This paper deal with the dynamics of an autonomous no storage wind-diesel system, comprising a diesel generator and a controlled wind system with a hypo/hyper synchronous cascade. The objective is to maximize the wind ... -
Sonar Target Localization Based on Spike Coded Spectrograms
("Dunarea de Jos" University of Galati, 2006)Target location is coded into the pattern of spikes that run up the auditory nerve to the bat's brain. Realistic scenes containing multiple, closely spaced, reflectors give rise to complex echo signals consisting of multiple ... -
Spatio-Temporal Dynamics in Celular Neural Networks
("Dunarea de Jos" University of Galaţi, 2009)Analog Parallel Architectures like Cellular Neural Networks (CNN’s) have been thoroughly studied not only for their potential in high-speed image processing applications but also for their rich and exciting spatio-temporal ... -
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 ... -
Speed and Rotor Flux Estimation in Speed Sensorless Control of Induction Motor
("Dunarea de Jos" University of Galati, 2002)The paper compares the performances of several adaptive rotor flux and speed estimation methods used in speed sensorless vector control of induction motor. First, a short review of Luenberger, Gopinath, MRAS, Torque Error ... -
Spread Data Storage-A Means Of Storing in Internet
("Dunarea de Jos" University of Galati, 2012)Recent years have led to the development of new data storage solutions, moving their local storage, to the storage in cloud (Internet). In this case, data loss raises greater problems, since there it is not able to seek ... -
Stability criteria for cellular neural networks
("Dunarea de Jos" University of Galati, 2001)A cellular neural network is an artificial neural network which features a multidimensional array of neurons and local interconnections among the cells. Neural networks are systems with several equilibrium states. It is ... -
