Research ArticleOpen accessIn the abstractOn Recipe Based Service Composition in Ubiquitous Smart SpacesJunaid A. Chowdary, Seung-Kyu Park, Suk-Kyo HongWe present a recipe based service composition scheme in smart spaces. We discuss real time problems of highly synchronized and user customizable processes with the help of an example. On-the-fly Quality of Service (QoS) shows up as a major issue in such environment. Furthermore the QoS of a dynamically composed service depends upon the aggregate QoS of its developing components. … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,766 accessesView PDFCite

RamadhanWith the introduction of Web-Based Instruction (WBI) the traditional classroom-based higher education could be made more effective form of instruction. But the studies have shown the negative results[1]. On the other hand the distance education has derived the direct benefit of WBI through extending classroom instruction in online to reach every remote student. However researchers have identified reasons for the … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,322 accessesView PDFCite

Research ArticleOpen accessIn the abstractRational Rules of Thumb in Finite Dynamic Games N-person Backward Induction with Inconsistently Aligned Beliefs and Full RationalityYanis VaroufakisRecent work has cast considerable doubt on the plausibility of specific assumptions about how rational agents form out-of-equilibrium beliefs in finite extensive games in which beliefs are induced backwards. The point is that the resulting consistently aligned beliefs are incoherent in view of the counterfactuals they rely on. This study asks: How will the possibility of inconsistently aligned beliefs affect … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 16 Dec 2005 · 8,117 accessesView PDFCite
