Abstract Multi-Agents Used in Industrial Fault Diagnosis
("Dunarea de Jos" University of Galati, 2012)Industrial diagnosis systems aim to anticipate the occurrence of failures or, if failures have occurred, to detect them and identify their cause, based on observable symptoms captured by sensors from the process. In case ... -
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 ... -
On Image Transmission in Communication Channels Using Alamouti Space-Time Codes
("Dunarea de Jos" University of Galati, 2012)Transmitting large amounts of data through wireless communication channels, at high speed and low error probability, is a major challenge for the researchers in the field. In this paper, aspects of image transmission in ... -
Numerical Evaluation of Reliability Indicators Under Optimal Renewal Strategies
("Dunarea de Jos" University of Galati, 2012)This paper investigates the opportunity of using a numerical procedure for computing the renewal parameters of an equipment. The reasons of this approach reside in the sampled way we measure the process variables and the ... -
Multiple Bistreams Generation Using Chaotic Sequences
("Dunarea de Jos" University of Galati, 2012)This article presents a method to transform a chaotic sequence of real numbers into multiple bitstreams, using multi-level discretization. Although the original intent was to achieve a higher/multiple flow of bits, much ... -
Designing a Modular Simulator for a Navigation Lock
("Dunarea de Jos" University of Galati, 2012)When building a simulator for an industrial installation, a divide and conquer approach can have very good results. This means that the original installation is divided into smaller components which are simulated independently ... -
Pill Model for Grid Voltage Reference Reconstruction
("Dunarea de Jos" University of Galati, 2012)In power electronics area, the PLL (Phase Lock Loop) circuit is needed to reconstruct the sinusoidal reference signal used on the APF (active power filters) or grid-tied inverters, starting from the distorted grid voltage. ... -
Modeling and Control of Assembly/Disassembly Mechatronic Line Served by Robotic Manipulator Mounted on Mobile Platform
("Dunarea de Jos" University of Galati, 2012)The new idea of this paper is to make reversible an assembly mechatronic line, i.e. to allow complete disassembly, by using a mobile platform equipped with robotic manipulator. The approach is a hybrid one, in which the ... -
Robust Routing Information Updating in IPV6 Networks
("Dunarea de Jos" university of Galati, 2012)The mechanism that classical routing protocols use to transmit routing updates and to maintain adjacency can be susceptible to packets loss and to bandwidth limitation. We propose a new method for transmitting routing ... -
