Research ArticleOpen accessIn the abstractImproving Mechanical Characteristics of Inverter-induction Motor Drive SystemHussein Sarhan, Rateb IssaAn inverter-three-phase squirrel-cage induction motor drive system with improved mechanical characteristics is presented. The proposed system provides mechanical characteristics with constant maximum torque or increased maximum torque and reduced slip speed at frequencies below the nominal frequency. The control algorithm is based on the constant volts per hertz principle using two improvement techniques: keeping maximum torque constant or keeping magnetic … …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Aug 2006 · 7,659 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Simulation-Based Comparison of Multimedia Traffic Prioritization Schemes for High-Performance Input-Queued Packet SwitchesSalman A. AlQahtaniThis study investigates the problem of enabling Quality of Service (QoS) of multimedia traffic at the input port of high-performance input-queued packet switches using a simulation-based evaluation. We focus on the possibility of assuring QoS of multimedia traffic in such switches by implementing traffic prioritization at the input port where each input-queue has been modified to provide a separate buffer … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 7,074 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Classification of Aspect Mining ApproachesBounour Nora, Ghoul Said, Atil FadilaIn object oriented paradigm, the implementation of a concern is typically scattered over many locations and tangled with the implementation of other concerns, resulting in a system that is hard to explore and understand. Identifying such code automatically greatly improves both the maintainability and the evolveability of the application. Aspect mining aims to identify crosscutting concerns in existing systems, thereby … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 6,774 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Dynamic Weight Assignment Approach for Index TermsKamel E. Haouam, Farhi MarirCurrently in the development of Informational Retrieval (IR) systems, a set of keywords represents the semantics of a text document and after assigning weights to the set of keywords, they are used for indexing, searching and retrieval purposes. The current approaches for assigning weights are provided by an IR model that is used by an IR system. The main objective … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,943 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomatic Discovery of Association Paths in Relational Databases Using Software VisualizationHaider Ali RamadhanWe introduce a visual framework for facilitating tasks associated with database maintenance and re-use. The prototype system embodying the framework is presented. The system utilizes various techniques and features of software visualization. The system supports visual displays of the database structure along with various implicit relationships found in it such as associations and path views. Information visualized is automatically extracted … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling Load Balancing in Heterogeneous Unstructured P2P SystemsZhi Jun Li, Ming Hong LiaoLoad balancing is a generally concerned problem in peer-to-peer (P2P) systems. Many researches on load balancing in the structured P2P systems have been launched currently, such as Chord or other DHTs. Although the researches on load balancing in unstructured P2P systems are emerged nowadays, the simple mechanisms achieved can only perform effectively in uniform environment. In this study, the influence … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,783 accessesView PDFCite
Research ArticleOpen accessIn the abstractConception and Development of a Dynamic Web Site: Dedicated to a University LibrarySafia Nait BahloulThe world wide web is a group of web pages related between them with hypertext links. That forms a huge and complex web mail. A single click allow us to surf from document to another. From each document we can refer to different types of information: text, sound, video. In most cases, first sites were static, their principal aim were … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,588 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimized Energy Efficient Virtual Machine Placement Algorithm and Techniques for Cloud Data CentersSanjay Patel, Ramji M. MakwanaCloud computing is an internet based computing technology that provide on demand computing for end users. Normally, data centers allocation for application on statically based. But today so many data centers have a problem how to reduce energy consumption? Due to increase use of cloud services and infrastructure by various cloud providers, uses of energy day by day increase that's … …Journal of Computer Science, Vol. 12, Issue 9 · 24 Nov 2016 · 7,356 accessesView PDFCite
Research ArticleOpen accessIn the abstractBinding Interaction between Bovine Serum Albumin and Chicoric Acid, a Food Functional ComponentHaifang Xiao, Quancai Sun, Xuebo Liu, Yuanda SongFuorescence, FTIR and UV-Vis absorption spectroscopy were used to explore the binding between chicoric acid and Bovine Serum Albumin (BSA). Binding characteristics at various levels of temperature have been calculated. The results indicated that chicoric acid statically quenched the intrinsic fluorescence of BSA. The binding constants (Ka) were 4.14×105 L mol-1 at 273K and 4.29×106 L mol-1 at 298 k. … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 3 · 19 Sep 2016 · 7,552 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiochemical Alterations in Zinc Deficient Sheep Associated by HyperlactatemiaAli Hafez El-FarBlood samples from diseased and clinically healthy Balady sheep of both sexes were collected and subjected for biochemical analysis of serum glucose, fructosamine, lactate, growth hormone, insulin, creatine phosphokinase, Lactate dehydrogenase and aldolase. The obtained results revealed a significant decrease in serum zinc and growth hormone were stated. In contrary, serum glucose and lactate, insulin, CPK, LDH and aldolase were … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 3 · 30 Aug 2013 · 6,908 accessesView PDFCite
