Research ArticleOpen accessIn the abstractAn Optimal Path Management Strategy in Mobile Ad Hoc Network Using Fuzzy and Rough Set TheoryP. Seethalakshmi, M. Joseph Auxilius Jude, G. RajendranProblem statement: Mobile Ad Hoc Network (MANET) is a collection of wireless mobile nodes that dynamically forms a network. Most of the existing ad-hoc routing algorithms select the shortest path using various resources. However the selected path may not consider all the network parameters and this would result in link instability in the network. The problems with existing methods are … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 15 Oct 2011 · 7,667 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Metadata Analysis and Base Analysis Techniques in Data Qualities Framework for Data WarehousesAzwa Abdul Aziz, Md Yazid Mohd Saman, Mohd Pouzi HamzahInformation provided by any applications systems in organization is vital in order to obtain a decision. Due to this factor, the quality of data provided by Data Warehouse (DW) is really important for organization to produce the best solution for their company to move forwards. DW is complex systems that have to deliver highly-aggregated, high quality data from heterogeneous sources … …American Journal of Economics and Business Administration, Vol. 3, Issue 1 · 31 Jan 2011 · 7,526 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Laboratory Study of Curiosity Behavior in Feedback-Based DecisionsTakemi FujikawaProblem statement: This study adopts an interdisciplinary approach in conducting the study on "curiosity" with a toolset of experimental economics. Approach: I hypothesized that the Decision Makers (DMs) tended to exhibit curiosity behavior when two conditions were met: (1) The DMs faced "small feedback-based" decision problems; (2) The DMs bore tangible costs of their curiosity behavior. Results: This study was … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,461 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Emerging Consumer Culture in Bangladesh: Everyday Life and Festivals in Rural AreasMd. Motaher HossainProblem statement: Bangladesh, often better known to the outside world as a country of natural calamities, is a poor and low-income country. Bangladesh’s main challenge is to reduce poverty through increasing equitable income. Although Bangladesh has faced many problems since its independence in 1971, its gross domestic product has been growing steadily and the country has achieved much success in … …Journal of Social Sciences, Vol. 6, Issue 3 · 30 Sep 2010 · 9,208 accessesView PDFCite
Research ArticleOpen accessIn the abstractAlgorithm Development for Measurement and Prediction the Traffic in Broad Band Integrated Service NetworksMohammad Al Rawajbeh, Ibrahim Mansi, Majed HussienProblem statement: In this study an effort had been made to develop an algorithm for traffic prediction and measurement for a wide use networks such as B-ISDN. Such algorithm should base on valuable parameters during the various stages of data elements transmission. The offered algorithm was expected to enforce the main sources of congestion problem in network. With this technique … …Journal of Computer Science, Vol. 6, Issue 10 · 10 Aug 2010 · 7,481 accessesView PDFCite
Research ArticleOpen accessIn the abstractStochastic Optimization for Portfolio Selection Problem with Mean Absolute Negative Deviation MeasureAnton Abdulbasah Kamil, Adli Mustafa, Khlipah IbrahimProblem statement: The most important character within optimization problem is the uncertainty of the future returns. Approach: To handle such problems, we utilized probabilistic methods alongside with optimization techniques. We developed single stage and two stage stochastic programming with recourse. The models were developed for risk adverse investors and the objective of the stochastic programming models is to minimize the … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 6,947 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Solution Methodology of Bi-Level Linear Programming Based on Genetic AlgorithmM. S. Osman, W.F. Abd El-Wahed, Mervat M.K. El Shafei, Hanaa B. Abd El WahabProblem statement: We deal with the bi-level linear programming problem. A bi-level programming problem is formulated for a problem in which two Decision-Makers (DMs) make decisions successively. Approach: In this research we studied and designs a Genetic Algorithm (GA) of Bi-Level Linear Programming Problems (BLPP) by constructing the fitness function of the upper-level programming problems based on the definition of … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,184 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulated Annealing with Deterministic DecisionsTaisir EldosProblem statement: Simulated Annealing (SA) algorithms have been used in solving a wide range of discrete optimization problems for many years, with well know drawbacks like the computational time and difficulties related to the parameters settings. One of the other issues that open the door for research is the acceptance decision that provides for hill climbing; the standard SA algorithms … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,119 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplying Simulated Annealing For Optimal Operation of Multi-Reservoir SystemsF. Khodabakhshi, A. R. Ghirian, N. KhakzadThe need to optimize the operation of water reservoirs is an issue that is becoming increasingly a concern for water resources planners in developing countries. This issue particularly becomes more significant in large systems with multiple reservoirs where operation of one reservoir has an impact on the others. In other word, the set of reservoirs in these systems act like … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,620 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Analysis of Urban Land Development Using Multi-Criteria Decision Model and Geographical Information System (A Case Study of Babolsar City)Sedigheh Lotfi, Kiomarth Habibi, Mohammad Javad KoohsariProblem Statement: The unplanned physical expansion of cities has been one of the most important problems of urban management in developing countries. Iran, like other developing world has experienced a high level of urbanization growth which transformed the physical fabric of urban areas. North of Iran is one of most rapid growing region of the country where the moderate climate … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 8,708 accessesView PDFCite
