Research ArticleOpen accessPhrase in the titleImplementation of Line Stability Index for Contingency Analysis and Screening in Power SystemsC. Subramani, Subhransu Sekhar Dash, Vivek Kumar, Harish KiranProblem statement: Estimating the margin in the loadability of the power system is essential in the real time voltage stability assessment. Voltage stability is currently one of the most important research areas in the field of electrical power system. In power system operation unpredictable events is termed as contingency and may be caused by line outage in the system which … …Journal of Computer Science, Vol. 8, Issue 4 · 11 Feb 2012 · 7,132 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Analysis of High Dimensional Contingency Table with InteractionsKeorapetse Sediakgotla, Lesego Gabaitiri, Keamogetse Setlhare et al.This paper is focused on the analysis of categorical data in a 2 × c × K contingency table. The theoretical frame work of a 2 × c design is extended to 2 × c × K with provision for testing interactions among subsets of either lower or upper columns of the designated table. The developed chi square tests for … …American Journal of Applied Sciences, Vol. 14, Issue 8 · 30 Aug 2017 · 7,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Rating of Operating Performance of Domestic Auto IndustryKuo-Wei Lin, Chia-Mu Kuan, Ming-Huang NiThe financial crisis in 2007 delivered a setback to the auto industry in Taiwan. However, the domestic auto companies had adopted various contingency measures that not only overcame the economic downturns but also enhanced their operating performances. It was the perfect storm. This study focuses on the changes of operating performances by domestic auto companies in Taiwan after financial crisis … …Journal of Computer Science, Vol. 8, Issue 11 · 15 Sep 2012 · 6,567 accessesView PDFCite
Research ArticleOpen accessIn the abstractDecompositions for Ordinal Quasi-Symmetry Model in Square Contingency Tables with Ordered CategoriesKouji Yamamoto, Satoru Shinoda, Sadao TomizawaProblem statement: For square contingency tables with ordered categories, this study considers four kinds of extensions of the marginal homogeneity model and gives decompositions for the ordinal quasi-symmetry model. The decompositions are extensions of some existing decompositions. Approach: This study gives a decomposition theorem that the ordinal quasi-symmetry model holds if and only if the quasi-symmetry model and the proposed … …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 28 Oct 2011 · 7,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractDecomposition of Marginal Homogeneity into Logit and Mean Ridits Equality for Square Contingency TablesKiyotaka Iki, Kouji Tahata, Sadao TomizawaProblem statement: For square contingency tables with ordered categories, if the Marginal Homogeneity (MH) model holds, then the probability that X selected at random from the row marginal distribution is less than Y selected independently at random from the column marginal distribution equals the probability that X is greater than Y. However, the converse does not hold. We are interested … …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 7,297 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 abstractAgricultural Waste Management Extension Education (AWMEE) The Ultimate Need for Intellectual ProductivityIraj Malek MohammadiExtension education is significant range of fields like Agriculture, Natural Resources, Environmental and Bio Diversity Conservation, Rural Development, Home Management Skill Development, Disaster Management, Waste Management, Value Adding Management. Among them, waste management extension is highly significant because of the millions of tons of annual waste in vegetal, animal, environmental and natural resources products as well as millions of hectors … …American Journal of Environmental Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 7,402 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAnalysis of Unaided Vision Data using New Decomposition of SymmetryKouji Yamamoto, Sadao TomizawaProblem statement: First, this study considers how the structure of symmetry for probabilities is decomposed into two structures. Secondly, this study infers the structure of unknown probabilities which indicates how the right eye is better (or worse) than the left eye for three kinds of data on unaided distance vision of (1) women in Britain, (2) students in an university … …Current Research in Medicine, Vol. 3, Issue 1 · 25 Feb 2012 · 7,449 accessesView PDFCite
