Research ArticleOpen accessEvery word in the titleSolving the Vehicle Routing Problem with Stochastic Demands via Hybrid Genetic Algorithm-Tabu SearchZ. Ismail, IrhamahThis study considers a version of the stochastic vehicle routing problem where customer demands are random variables with known probability distribution. A new scheme based on a hybrid GA and Tabu Search heuristic is proposed for this problem under a priori approach with preventive restocking. The relative performance of the proposed HGATS is compared to each GA and TS alone, … …Journal of Mathematics and Statistics, Vol. 4, Issue 3 · 30 Sep 2008 · 7,957 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePerformance Comparison of Two On-demand Routing Protocols for Ad-hoc Networks based on Random Way Point Mobility ModelGeetha Jayakumar, G. GopinathAd hoc networks are characterized by multihop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols plays an important role. We compare the performance of two prominent on-demand routing protocols for mobile ad hoc networks: Dynamic Source Routing (DSR), Ad Hoc On-demand distance Vector Routing (AODV). A detailed simulation model with MAC and physical layer … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,693 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAggregate Import Demand and Expenditure Components in GhanaOteng-Abayie Eric Fosu, Frimpong Joseph MagnusThe behaviour of Ghana’s imports during the period 1970-2002 was studied using disaggregated expenditure components of total national income. We used newly developed bounds testing approach to cointegration and estimated an error correction model to separate the short- and long-run elements of the import demand relationship. The study revealed inelastic import demand for all the expenditure components and relative price. … …Journal of Social Sciences, Vol. 4, Issue 1 · 31 Mar 2008 · 7,769 accessesView PDFCite

A much more crucial paradox, as far as certain European countries are concerned, is produced by the inertia of the democratic game it self. That is the construction of religious and ethnic affiliation as the very entrance … …Journal of Social Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 7,744 accessesView PDFCite

Crustacean waste is the most important chitin source for commercial use. Demineralization is an important step in the chitin purification process from crustacean waste. … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 1 · 31 Mar 2007 · 8,806 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleE-DemocracyKevin Curran, Eric NicholsDemocracy means majority rule. This raises some interesting questions. In a truly democratic society, when a majority of citizens vote for one candidate to govern them, then that person would be the elected governor of those people. Following this line of reasoning, if the majority of people do not vote for a leader, does democracy mean not having a leader? … …Journal of Social Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,068 accessesView PDFCite
