Research ArticleOpen accessIn the abstractEnhanced Route Re-Construction Method for Associativity Based Routing Protocol for Mobile Ad hoc NETworks (MANET)Fawaz A.M. Masoud, Said A. Shaar, Ayman Murad, Ghassan KanaanA mobile Ad-hoc NETwork (MANET) is wireless network composed of mobile nodes that are dynamically and randomly located in such a manner that the interconnections between nodes are capable of changing on a continual basis. In order to facilitate communication within the network, a routing protocol is used to discover routes between nodes. The primary goal of such an ad-hoc … …Journal of Computer Science, Vol. 2, Issue 12 · 31 Dec 2006 · 6,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractMobile Agents in Heterogeneous Networks: A Look on PerformanceR. B. Patel, Neeraj GoelMobile agents can be seen as a new paradigm for distributed computing. One characteristic of mobile agents is their autonomy and pro-activity. This article present a framework designed on top of PMADE (Platform for Mobile Agent Distribution and Execution) to support our research in this domain. Our framework consists of three modules. The Map Module collects information on the available … …Journal of Computer Science, Vol. 2, Issue 11 · 30 Nov 2006 · 6,490 accessesView PDFCite
Research ArticleOpen accessIn the abstractModelling and Forecasting Volatility of Returns on the Ghana Stock Exchange Using Garch ModelsFrimpong Joseph Magnus, Oteng-Abayie Eric FosuThis paper models and forecasts volatility (conditional variance) on the Ghana Stock Exchange using a random walk (RW), GARCH(1,1), EGARCH(1,1), and TGARCH(1,1) models. The unique ‘three days a week’ Databank Stock Index (DSI) was used to study the dynamics of the Ghana stock market volatility over a 10-year period. The competing volatility models were estimated and their specification and forecast … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 7,551 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Implementing Calls Prioritization with Different Queuing Disciplines in Mobile Wireless NetworksSalman A. AlQahtani, Nasser-Eddine RikliIt is known that efficient call handling mechanisms can greatly improve cellular network performance. One way to improve system performance of cellular network is to use efficient handover schemes when users changes between cells. This paper focuses on the performance evaluation of originating and handover calls prioritization using different queue size and discipline. Both calls will be queued until they … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,470 accessesView PDFCite
Research ArticleOpen accessIn the abstractMPLS over Segmented WDM Optical Packet Switching NetworksHakim Mellah, Fouad M. AbbouWavelength Division Multiplexing (WDM) is a promising solution for data transport in future all-optical wide area networks. Such networks consist of fibers joined by dynamically controllable cross-connects which provide purely optical transport between pairs of network access stations. Optical packet switching (OPS) is optical switching with the finest granularity. Incoming packets are switched all-optically without being converted to electrical signal. … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,750 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimating the Optimal Farm Size under Uncertainty: an Application of Real Options MethodologyAnastasios Ch. Michailidis, Konstadinos A. MattasFarm structure and optimal farm size have always attracted the interest of research as they constitute some of the intense problems of farm efficiency and farm income. Although several approached have been employed to handle with this problem a real options approach can significantly contribute on this matter. This article provides an empirical example of applying real options approach in … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 1 · 31 Mar 2006 · 7,664 accessesView PDFCite
Research ArticleOpen accessIn the abstractLocation Based Throughput Maximization Routing in Energy Constrained Mobile Ad-hoc NetworkV. Sumathy, P. Narayanasamy, R. PrabhuIn wireless Ad-hoc network, power consumption becomes an important issue due to limited battery power. One of the reasons for energy expenditure in this network is irregularly distributed node pattern, which impose large interference range in certain area. To maximize the lifetime of ad-hoc mobile network, the power consumption rate of each node must be evenly distributed and the over … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,823 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlow of Dividends under a Constant Force of InterestJuma Kasozi, Jostein PaulsenThis study addresses the issue of maximization of dividends of an insurer whose portfolio is exposed to insurance risk. The insurance risk arises from the classical surplus process commonly known as the Cramér-Lundberg model in the insurance literature. To enhance his financial base, the insurer invests in a risk free asset whose price dynamics are governed by a constant force … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,386 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Stability of a Certain Class of Linear Time-Varying SystemsM. De la SenThis study firstly considers the exponential stability of unforced linear systems of slowly time-varying dynamics. Possible switchings of the system structure to unstable dynamics during certain finite time intervals are admitted. The maintenance of global exponential stability does not necessarily require at most a finite number of switchings in the dynamics while infinitely many switches can also lead to stability. … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,935 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Neural Network for Generating Adaptive LessonsHassina Seridi-Bouchelaghem, Toufik Sari, Mokhtar SellamiTraditional sequencing technology developed in the field of intelligent tutoring systems have not find an immediate place in large-scale Web-based education. This study investigates the use of computational intelligence for adaptive lesson generation in a distance learning environment over the Web. An approach for adaptive pedagogical hypermedia document generation is proposed and implemented in a prototype called KnowledgeClass. This approach … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 7,269 accessesView PDFCite
