Research ArticleOpen accessIn the abstractTrade Related Environmental Measures in Multilateral Environmental Agreements and the WTO: Irreconcilable Differences?Nidhi SinghProblem statement: WTO adopted a multilateral trading system without ignoring the importance of protecting environment. Exceptions in Article XX, Clause (b) and (g) checks trade at the cost of environment. It is difficult to establish a relationship between Trade Related Environmental Measures (TREMs) in Multilateral Environmental Agreements (MEAs) and World Trade Organization (WTO) rules. For the past ten years there … …American Journal of Economics and Business Administration, Vol. 1, Issue 3 · 30 Sep 2009 · 8,621 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetically Modified Organism Trade Route and Biosafety-Is It a Failing Synthesis?Debdatta Dobe, Rohini SenProblem statement: GM regulations have spawned international conflicting reactions especially between US and EU, with countries requiring food aid caught midway. This article covers the following issues: Whether biotechnology policies of other countries affect the developing countries’ trade in agricultural crops?" Does unregulated GM expansion and contamination, render the system fallacious? Can there be synthesis between trade and environment? Approach: … …American Journal of Economics and Business Administration, Vol. 1, Issue 3 · 30 Sep 2009 · 7,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Original Geometric Programming Problem Algorithm to Solve Two Coefficients Sensitivity AnalysisAbbas Y. Al-Bayati, Huda E. KhalidProblem statement: It has been noticed by Dinkel and Kochenberger that they developed sensitivity procedure for Posynomial Geometric Programming Problems based on making a small changes in one coefficient. Approach: This study presented an original algorithm for finding the ranging analysis while studying the effect of perturbations in the original coefficients without resolving the problem, this proposed procedure had been … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,366 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Approach to Modeling Software Safety in Safety-Critical SystemsBen Swarup Medikonda, Seetha Ramaiah PanchumarthySoftware for safety-critical systems has to deal with the hazards identified by safety analysis in order to make the system safe, risk-free and fail-safe. Software safety is a composite of many factors. Problem statement: Existing software quality models like McCall’s and Boehm’s and ISO 9126 were inadequate in addressing the software safety issues of real time safety-critical embedded systems. At … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,732 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Nonlinear Optimal Feedback Law for Satellite Injection Problem Using Neighboring Optimal ControlHamed Hossein Afshari, Alireza Basohbat Novinzadeh, Jafar RoshanianAn optimal trajectory design of a nonlinear satellite injection problem for transfer to a final target orbit by minimizing the time was investigated. Indeed, this design was an exact solution to the nonlinear two-point boundary value problem which determined optimal control history as well as optimal state trajectories in the open-loop form. Furthermore, the obtained optimal guidance strategy was exerted … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 7,256 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical and Biological Responses of Forests to Tropical Cyclones Affecting the United States Atlantic Ocean and Gulf of Mexico CoastsKrista Merry, Pete Bettinger, Jeffrey HepinstallProblem Statement: Natural resources within the southern United States have repeatedly been subjected to the impact of tropical cyclones. While the frequency of tropical cyclones hitting either coast varies from year to year, it is crucial for natural resource managers and land owners to be prepared for the damage resulting from such storms. The goal of this review paper is … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Sliding Mode Command for a System of Coupled ReservoirsRiadh Gamoudi, Mahmoud Ellouze, Abdelkader MamiThis study consisted to determine a discreet order by sliding method that was applied on a regulation procedure of a formed level by communicating reservoirs. The model that represents the system is determined by parametric identification based on the algorithm of the recursive least square with forgetfulness factor. Problem statement: The purpose is to develop a robust order that assuring … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 6,551 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of Distributed Architecture Based on Internet GIS for Geomorphologic Data and Environmental Management: Case Study of Damavand Volcano Conic, IranEbrahim Moghimi, Ali Mansourian, Mojgan Zarei Nejad, Mohammad Saber MoghimiDespite the great significance of geomorphologic-environmental data in different disciplines, there are sundry problems in relation to availability, accessibility and their applicability. Primarily the problems dealing with these data were investigated and then technical solutions to remove each of the above problems and how to manage geomorphologic-environmental data were suggested. The solution for availability lies in participation of various organizations … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,046 accessesView PDFCite
Research ArticleOpen accessIn the abstractSelf-Generation ART-1 Neural Network with Gradient-Descent Method Aid for Latin Alphabet RecognitionMbaïtiga ZacharieProblem statement: In this study a self-generation ART-1 neural network that is an efficient algorithm that emulates the self-organizing pattern recognition developed to avoid the stability-plasticity dilemma in competitive networks learning, is presented for Latin alphabet recognition to use in a vision system for road sings recognition. Approach: The first step of our approach deals with the training process where … …Journal of Computer Science, Vol. 4, Issue 8 · 31 Aug 2008 · 6,566 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectronic Energies in Delta Doped AlGaAs/GaAs HeterostucturesA. Meftah, H. Ajlani, A. Marzouki et al.The band bending of the potential at the AlGaAs/GaAs interface increases with the electrons concentration in the GaAs channel. This band bending is often ignored in the theoretical calculation of the electronic energies and a linear potential approximation was used. This led to imprecise energy values and occupied subband configurations. We have taken account of the band bending in the … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 6,931 accessesView PDFCite
