Research ArticleOpen accessIn the abstractNew Approach to Compute Integral TransformsA. Adawi, F. AwawdehIntegral transforms find special applicability within scientific and mathematical disciplines. A powerful and efficient homotopy methodology in evaluating integrals arises in integral transforms was presented. The method depends on solving a related first order linear differential equation by homotopy analysis method HAM. The Laplace transform, Fourier transform and the moment generating function of the standard normal distribution were used as … …Journal of Mathematics and Statistics, Vol. 4, Issue 2 · 30 Jun 2008 · 6,718 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Ethical Appraisal of Hormesis: Towards a Rational Discourse on the Acceptability of Risks and BenefitsOrtwin RennIt is ethically mandated that potential beneficial aspects of low exposure to potentially hazardous material are incorporated in the risk-benefit balancing procedure. The potential harm done by pollutants does not justify the invocation of a categorical principle. Minimisation of risk is not required if health benefits are also at stake. Society needs to find an informed consent on the threshold … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,080 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Modelling of an Industrial Smelter Furnace and Converter Off-gas SystemHelen Shang, Megan Dillabough, Phillip Nelson, Bryan SaltIn smelters, metal ores or concentrates are smelted to reduce a metal oxide to a metal through a series of reactions and processes. In a smelting process, a large amount of off-gas emissions are often generated, which can cause serious environmental and plant hygiene problems if not properly treated. Off-gas systems extract and treat the off-gas emissions, and ensure that … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 7,158 accessesView PDFCite
Research ArticleOpen accessIn the abstractGOSTE: Group Oriented Simulation Training EnvironmentKorichi Ahmed, Belattar BrahimThe purpose of this study is to explore the contribution of the CSCW (Computer Supported Cooperative Work) in the collaborative project conduct and more specifically in the conduct of a simulation training project. We justify the adequacy of the CSCW concepts with the method of conduct of a simulation project. The practice of the web-based simulation as well as the … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,988 accessesView PDFCite
Research ArticleOpen accessIn the abstractModule Management Tool in Software Development OrganizationsAhmad A. Al-Rababah, Mohammad A. Al-RababahModule management is an important task at developers’ level in software development organizations. So we consider in this paper software as collection of several modules. Also we study a method of clustering of modules of a large software system. The need of doing such clustering is justified to be an important part of software management in the software development organizations. … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 7,038 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Bayes Estimation of the First Order Moving Average ModelMahmoud M. Smadi, Ahmed A. Abu-TalebIn this work, Bayes estimation of the first order moving average model (MA(1)) were studied. Theoretical justification of the Bayes estimates based on the estimated innovations is given. The convergence of Bayes and maximum likelihood estimates are examined via simulation using different parameter values. Also, Bayes estimates were determined when the model is invertible using the estimated innovations. For long … …Journal of Mathematics and Statistics, Vol. 2, Issue 3 · 30 Sep 2006 · 6,524 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurvival in the Current Healthcare Environment How Close Are We to Socialized Medicine?Eldo E. FrezzaIn the 1980's, some hospitals established internal agencies to regulate cash flow and capital expense. State agencies promoted the evolution of healthcare facilities into more business-like organizations. Attention to the following matters will reduce hospital costs: 1) prevent or reduce nosocomial infections; 2) treat diseases at a stage amenable to outpatient therapy; 3) obtain complete information about the policies of … …Journal of Social Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 6,693 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrice-Taking in General EquilibriumMurray C. KempThe Arrow-Debreu and McKenzie existence propositions of 1954 rest on the assumption of price-taking behaviour by households and firms. No attempt was made to justify the assumption or to relate it to other assumptions. It is here suggested that, given other assumptions common to the Arrow-Debreu and McKenzie models, price-taking implies that each household is incompletely informed and/or incompletely rational. … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 22 Dec 2005 · 7,721 accessesView PDFCite
