Research ArticleOpen accessIn the abstractA Dynamic Resource Synchronizer Mutual Exclusion Algorithm for Wired/Wireless Distributed SystemsAhmed Sharieh, Mariam Itriq, Wafa DbabatA mobile host has small memory, relatively slow processor, low power batteries, and communicate over low bandwidth wireless communication links. Existing mutual exclusion algorithms for distributed systems are not enough for mobile systems because of several limitations. In this study, a mutual exclusion algorithm that is more suitable for mobile computer systems is developed. The algorithm tends to minimize the … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,161 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Deduced Protein Database Using Variable Bit Binary EncodingB. Parvathavarthini, B. Rajesh Kanna, L. RajeswarideviA large amount of biological data is semi-structured and stored in any one the following file formats such as flat, XML and relational files. These databases must be integrated with the structured data available in relational or object-oriented databases. The sequence matching process is difficult in such file format, because string comparison takes more computation cost and time. To reduce … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,512 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Conceptual Design of Module Documentation Based Testing ToolSalmi Baharom, Zarina ShukurSoftware testing plays an important role to assure the quality of software and can be highly effective if performed rigorously. Studies found that testing can benefit from formal specification as it provides precise description of expected software behavior and most importantly, it is in a form that it can be manipulated easily for automation purpose. Grey-box testing approach usually based … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,532 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Error Correction Intuitive Approach in Quantum Communications ProtocolsAris Skander, Merabtine Nadjim, Malek BenslamaQuantum Error Correction will be necessary for preserving coherent states against noise and other unwanted interactions in quantum computation and communication. We develop a general theory of quantum error correction based on encoding states into larger Hilbert spaces subject to known interactions. We obtain necessary and sufficient conditions for the perfect recovery of an encoded state after its degradation by … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 6,838 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of AODV in Wireless Ad Hoc NetworksZeyad M. Alfawaer, GuiWei Hua, Nidal A. HamdehAODV is a mature and widely accepted routing protocol for Mobile Ad hoc Networks (MANET), it has low processing and memory overhead and low network utilization, and works well even in high mobility situation. We modified AODV to use these dominating sets, resulting in the AODV-DS protocol. Our contribution in addressing the fragility of a minimum connected dominating set in … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 7,160 accessesView PDFCite
Research ArticleOpen accessIn the abstractGas Turbine Ontology for the Industrial ProcessesF. Z. Laallam, M. SellamiThe activity of supervision and control of the industrial processes is a very complex spot and require a great experiment because of the dynamic characteristics of the process. This experiment was acquired with the passing of years. What makes departure of an expert in retirement a great loss of the know-how. The problem thus consists to capture this know-how and … …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 7,298 accessesView PDFCite
Research ArticleOpen accessIn the abstractPacked Forest Chart ParserQi Haoliang, Li Sheng, Yang Muyun, Zhao TiejunPacked forest chart parser, like the traditional chart parsing algorithm, uses charts to store all the information produced while parsing to avoid redundant works. Its advantage over the traditional chart parser was the packed forest representation. The algorithm not only shares the non-terminal categories as what was done in the shared parse forest, but also shares the leftmost common elements. … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 6,556 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Network on Chip resources allocation for QoS ManagementAbdelhamid HELALI, Adel SOUDANI, Jamila BHAR, Salem NASRIThe increasing complexity of integrated circuits and application requirements drive the research of new on-chip interconnection architectures. A network on chip draws on concepts inherited from distributed systems and computer networks subject areas to interconnect IP cores in a structured and scalable way. The main goal pursued is to achieve superior bandwidth when compared to conventional on-chip bus architectures. The … …Journal of Computer Science, Vol. 2, Issue 10 · 31 Oct 2006 · 6,307 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of an IP Library for the Synthesis of Image Compression SystemsChokri Souani, Ihsen Gazzah, Kamel BesbesTo design a hardware system we may use generated Intellectual Property (IP) cores from a library with optimized parameters. The IP parameters are area minimization, memory use optimization and speed acceleration. The designed system depends on such IP parameters. In this paper, we propose the design of an IP library optimized with different constraints. The created IPs may be used … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,458 accessesView PDFCite
