Research ArticleOpen accessPhrase in the titleAn 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 accessPhrase in the titleSensitivity Analysis of an Optimal Access Road Location in HillyForest Area: A GIS ApproachMohd I. Hasmadi, J.C. TaylorThere are various models for establishing the efficient forest road allocation and evaluating optimum density of forest roads network for the transport of timber commodity. Most of them are based on the calculation of common timber transport costs and costs for forest roads. Today, forest road design from traditional method continues to be transformed by remote sensing technology and advancement … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,609 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAntibiotic Sensitivity Pattern of Blood Isolates of Acinetobacter Species in a Tertiary Care Hospital: A Retrospective AnalysisP. S. Shareek, D. Sureshkumar, Ramgopalakrishnan et al.Problem statement: Multi-drug resistant Acinetobacter bacterium is one of the major causes of sepsis in ICUs in tertiary care hospitals in India. In this report we describe the antibiotic sensitivity patterns of Acinetobacter species isolated from blood over a one year period at a tertiary care hospital. Approach: We retrospectively analyzed the sensitivity pattern of Acinetobacter species isolated from blood … …American Journal of Infectious Diseases, Vol. 8, Issue 1 · 24 Mar 2012 · 8,564 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOn the Sensitivity of a Dynamic Measure of Financial InequalityGuglielmo D’Amico, Stefania Scocchera, Loriano StorchiIn the present work, we investigate the sensitivity of the dynamic Theil index computed under a Markov reward model with respect to structured perturbations affecting the underlying Markov process. The model is applied to the sovereign credit spread evolution as a proxy for financial risk, which are driven by the sovereign credit rating dynamic. The introduction of such perturbations allows … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 25 Oct 2019 · 7,264 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGenerator Dynamic Performance Affected by Parameter’s UncertaintyAkbar Beik Khormizi, Mohammad Reza Aghamohammadi, Mina RezaeeThis study investigates the effect of generator parameters inaccuracy on the transient stability performance of generator and power system. Normally, generator parameters are identified either by calculation based on design specification or by measurements. In both approaches the parameters are obtained with some degree of inaccuracy. Inaccuracy and uncertainty in the obtained parameters can affect the dynamic performance and transient … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 8 Jun 2013 · 6,630 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Study on the Increase of Numerical Stability and Accuracy of the Transfer Matrix MethodIoannis S. Zotos, Theodore N. CostopoulosProblem Statement: The transfer matrix method is a very useful tool for the static and dynamic analysis of structures. There are a number of issues though that worsens the numerical stability and the accuracy of this method. Approach: This study proposed a simple technique that can be used to handle these numerical difficulties and overcome the problems they give. Its … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,030 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimal Control of the D-Policy M/G/1 Queueing System with Server BreakdownsKuo-Hsiung Wang, Ching-Chang Kuo, Jau-Chuan KeThis study deals with a single server in the D-policy M/G/1 queueing system in which the server is turned off at the end of each complete period and is activated again only when the cumulative completion times of the customers in the system exceeds a given level D. While the server is working, he is subject to breakdowns according to … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,604 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTolerances Applied in Combinatorial OptimizationBoris Goldengorin, Gerold Jäger, Paul MolitorIn this paper we deal with sensitivity analysis of combinatorial optimization problems and its fundamental term, the tolerance. For three classes of objective functions (∑, ∏, MAX) we give some basic properties on upper and lower tolerances. We show that the upper tolerance of an element is well defined, how to compute the upper tolerance of an element and give … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 18,423 accessesView PDFCite

SkopinThe theoretical outcomes and experimental results of applying of Artificial Neural Networks towards mortality structure examination in Russian Federation are presented in the paper. The most influencing classes of diseases are selected by sensitivity analysis. It is proved that Neural Network Models appear to be an adequate tool for mortality structure examination. Some interesting results for males and females total … …American Journal of Applied Sciences, Vol. 3, Issue 2 · 28 Sep 2006 · 7,056 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Economic Feasibility of Rebuilding Al-Isra University Tunnel — Mechanical FactorsBassam Al-HelouEconomic feasibility is the cornerstone in the decision making on an economic venture. The more positive the economic signs, the less the risk and foreseen losses. This study throws light on some economic advantages of rebuilding Al-Isra tunnel, especially in terms of shortening the car/bus trip by six kilometers go and fro, and in terms of reducing the trip schedule … …American Journal of Applied Sciences, Vol. 3, Issue 4 · 30 Apr 2006 · 7,154 accessesView PDFCite
