Research ArticleOpen accessIn the abstractComputer Arithmetic Algorithms for Mega-Digit Floating Point Numbers' PrecisionMusbah J. Aqel, Mohammed H. SalehIEEE standard 754 floating point is the most common representation used for floating point numbers, and many computer arithmetic algorithms are developed for basic operations on this standard. In this study, new computer algorithms are proposed to increase the precision range and to solve some problems that are available while using these algorithms. However, these algorithms provide an optional range … …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 6,649 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring Strategies for Parallel Computing of RS Data Assimilation with SWAP-GAShamim Akhter, Kiyoshi Honda, Yann Chemin, Putchong UthayopasAn agro-hydrological simulation model is useful for agriculture monitoring. One issue in running such model is parameter identification, especially when the target area is large such as provincial or country level. Remote Sensing (RS) provides us with useful information over large area. RS cannot observe input parameters of agro-hydrological models directly. However, a method to estimate input parameters of such … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 7,209 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards an Exclusion Mutual Tolerant Algorithm to FailuresM. Senouci, A. Liazid, D. BenhamamouchThe distributed algorithmic is widely used in various economic and industrial fields as finance, medical, industry, telecommunication. New technologies are increasing rapidly. From now on, applications must associate two conditions: auto-execution on heterogeneous grid computers, on the one hand and on the other hand, satisfaction of the temporal and safety constraints. Hence this paper deals with performing an algorithm based … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 6,726 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeterministic Timed AFA: A New Class of Timed Alternating Finite AutomataAbdelaziz Fellah, Zachary Friggstad, Soufiane NoureddineTimed Alternating Finite Automata (TAFA), a natural generalization of Timed Finite Automata (TFA), are synchronous and powerful models for real-time computations. They become an effective and expressive model for developing embedded systems with real-time constraint computations which are required in many applications. We introduce Deterministic Timed Alternating Finite Automata (DTAFA), a new class of timed alternating finite automata, extended with … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 7,499 accessesView PDFCite

Research ArticleOpen accessIn the abstractE-Government Readiness Assessment ModelAhmed Al-Omari, Hussein Al-OmariThis study presents a general framework model for E-Government Readiness Assessment. There are six necessary key factors to implement any E-government initiative worldwide. These factors represent the basic components to be assessed before launching the "e-initiative" to guarantee the right implementation in the right direction. The organization building blocks need to be assessed are: Organizational Readiness, Governance and leadership Readiness, … …Journal of Computer Science, Vol. 2, Issue 11 · 30 Nov 2006 · 8,307 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Hybrid Mobile Agent Protocol for Wireless Multihop Internet AccessA. Velmurugan, R. RajaramInternet-based Mobile Ad Hoc Networking (MANET) is an emerging technology that supports self-organizing mobile networking infrastructures. This is expected to be of great use in commercial applications for the next generation Internet users. A number of technical challenges are faced today due to the heterogeneous, dynamic nature of this hybrid MANET. A new hybrid routing scheme AODV_ALMA is proposed, which … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,119 accessesView PDFCite
Research ArticleOpen accessIn the abstractSome Enabling Technologies for Ubiquitous NetworksJunaid A. Chaudhry, Chaudhry S. Hussain, Seungkyu ParkEvery new technology that makes its way in the market is supported by a collection of core components called enabling technologies. These components play a major role in making that new technology a success. In this paper we discuss Autonomic Computing (AC) and especially self management and Service Discovery (SD) as the enabling technologies for ubiquitous networks. The AC puts … …Journal of Computer Science, Vol. 2, Issue 8 · 31 Aug 2006 · 6,536 accessesView PDFCite
Research ArticleOpen accessIn the abstract2D Object Description with Discrete SegmentsNbhan D. Salih, David C.L. Ngo, Hakim Mellah2D object shape description has gained considerable attention in field of content-based image retrieval (CBIR) and in various applications that concerned with the shapes of objects. Object shape descriptors in the literature are commonly classified into two forms: contour-based and region-based. In this paper we present our contour-based shape representation and description, where the object shape is represented and describe … …Journal of Computer Science, Vol. 2, Issue 7 · 31 Jul 2006 · 6,540 accessesView PDFCite
