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 · 7,661 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutonomic Middleware Services for Just-In-Time Grid Services ProvisioningWail M. Omar, A. Taleb-Bendiab, Yasir KaramThe advent of widespread distributed computing environment, such as information systems and computational grids computing has enabled a new generation of applications that are based on seamless access, aggregation and interaction. The dramatic side of the story is a strong presence of the plea that those decentralized Grids are potentially affected by a number of primitives derived from their anatomy, … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 6,584 accessesView PDFCite
Research ArticleOpen accessIn the abstractPredictive Autonomicity of Web Services in the MAWeS FrameworkEmilio P. Mancini, Massimiliano Rak, Roberto Torella, Umberto VillanoIn Web Services designs classical optimization techniques are not applicable. A possible solution to guarantee critical requirements is the use of an autonomic architecture, able to auto-configure and to auto-tune. This study presents MAWeS (MetaPL/HeSSE Autonomic Web Services), a framework whose aim is to support the development of self-optimizing predictive autonomic systems for Web service architectures. It adopts a simulation-based … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 7,073 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutonomic and Dependable Computing: Moving Towards a Model-Driven ApproachYuan S. Dai, Tom Marshall, Xiaohong GuanThe rapidly increasing complexity of computing systems is driving the movement towards autonomic systems that are capable of managing themselves without the need for human intervention. Without autonomic technologies, many conventional systems suffer reliability degradation and compromised security. Autonomic management techniques reverse this trend. This study describes the roles and functions of various autonomic components, and systematically reviews past and … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 6,303 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioceramics for Tissue Engineering Applications-A ReviewSunho Oh, Namsik Oh, Mark Appleford, Joo L. OngThree dimensional (3-D) scaffolds have been explored in an attempt to persuade the body to heal or repair tissues that do not do so spontaneously. Considerable advances in tissue engineering and regeneration have been accomplished over the last decade. However, the material and 3-D scaffolds ideal for optimal regeneration of missing or lost tissues has not been identified. While current … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 10,423 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 · 6,778 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntelligent Control for Self-erecting Inverted Pendulum Via Adaptive Neuro-fuzzy Inference SystemA. A. Saifizul, Z. Zainon, N. A.Abu Osman et al.A self-erecting single inverted pendulum (SESIP) is one of typical nonlinear systems. The control scheme running the SESIP consists of two main control loops. Namely, these control loops are swing-up controller and stabilization controller. A swing-up controller of an inverted pendulum system must actuate the pendulum from the stable position. While a stabilization controller must stand the pendulum in the … …American Journal of Applied Sciences, Vol. 3, Issue 4 · 30 Apr 2006 · 7,326 accessesView PDFCite
Research ArticleOpen accessIn the abstractTaxonomically Clustering Organisms Based on the Profiles of Gene Sequences Using PCAE. Ramaraj, M. PunithavalliThe biological implications of bioinformatics can already be seen in various implementations. Biological taxonomy may seem like a simple science in which the biologists merely observe similarities among organisms and construct classifications according to those similarities[1], but it is not so simple. By applying data mining techniques on gene sequence database we can cluster the data to find interesting similarities … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,753 accessesView PDFCite
