Research ArticleOpen accessIn the abstractNew Entry, International Location Patterns and WelfareWataru JohdoProblem statement: Recently, firms have very actively invested across national borders and the international concentration of industrial activities in emerging countries and developed countries has been rapid. In the new international trade literature, static trade models with firms’ location have been widely used, but do not allow for endogenous spatial distribution of firms in the literature. In addition, few studies … …American Journal of Economics and Business Administration, Vol. 1, Issue 2 · 30 Jun 2009 · 7,225 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Block-Based Multi-Scale Background Extraction AlgorithmSeyed Hashem Davarpanah, Fatimah Khalid, Maryam GolchinProblem statement: To extract the moving objects, vision-based surveillance systems subtract the current image from a predefined background image. The efficiency of these systems mainly depends on accuracy of the extracted background image. It should be able to adapt to the changes continuously. In addition, especially in real-time applications the time complexity of this adaptation is a critical matter. Approach: … …Journal of Computer Science, Vol. 6, Issue 12 · 6 Nov 2010 · 7,213 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Discrete Event Modeling and Simulation of Wave Division Multiplexing Unidirectional Slotted Ring Metropolitan Area NetworkH. A. Fua’ad, S. Shamala, M. Othman, Z. ZuriatiProblem statement: The lack of uniformity in the choice of simulation platforms for optical WDM networks stands behind the difficulty of developing a common simulation environment. Correlating WDM unidirectional slotted ring network to Discrete Event Simulation (DES) encompassing event definition, time advancing mechanism and scheduler has yet to be developed. Approach: The study focused on the proposed and the development … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 6,680 accessesView PDF Cite
