Research ArticleOpen accessEvery word in the titleOn 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 accessEvery word in the titleAN EXAMINATION OF THE GROWING LEVEL OF INCOME INEQUALITYAllen L. WebsterThis study examines the dispute surrounding the perceived gap in incomes of different socio-economic classes. The trend in income inequality based on the Gini coefficient in America in contrast to that of other nations in the Organization for Economic Cooperation and Development is displayed. Global and national forces seen as causes for the increased separation of income levels are discussed. … …American Journal of Economics and Business Administration, Vol. 6, Issue 1 · 2 Apr 2014 · 6,902 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBoundary Distributions with Respect to Chebyshev's InequalityPeter Bias, Shawn Hedman, David RoseVariables whose distributions achieve the boundary value of Chebyshev’s inequality are characterized and it is found that non-constant variables with this property are symmetric discrete with at most three values. Nevertheless, the bound of Chebyshev’s inequality remains optimal for the class of continuous variables. …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 8,633 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHow Serious Regional Economic Inequality in Jordan? Evidence from Two National Household SurveysMohammed Issa ShahateetThe objective of this study is to measure and explain the extent of regional economic inequalities in Jordan. To do so, this study uses the raw data of two national household surveys on expenditure and income that covers 5,971 and 11,153 households in 1997 and 2002, respectively. As a check on the empirical results, the study applies four measures of … …American Journal of Applied Sciences, Vol. 3, Issue 2 · 28 Feb 2006 · 7,212 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleE-Saddle Point Criteria for E-differentiable Vector Optimization Problems with Inequality and Equality ConstraintsTadeusz Antczak, Najeeb Abdulaleemn this study, the class of E-differentiable vector optimization problems with both inequality and equality constraints is considered. For such (not necessarily) differentiable multicriteria optimization problems, two E-Lagrange functions and their E-saddle points are defined. Then the so-called E-saddle point criteria are established for such (not necessarily) differentiable multiobjective programming problems with E-differentiable E-convex functions. …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 11 May 2019 · 7,401 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn a Proof of Inequality of PvsNPAngelo Raffaele MeoThis study is a new version of a previous paper. Its purpose is to simplify some sections of the old version and, above all, to present the proofs of some theorems which had been omitted for the sake of brevity. The analysis discussed in this study and its previous version is based on a well-known NP-complete problem which is called … …Journal of Computer Science, Vol. 19, Issue 1 · 16 Jan 2023 · 7,531 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn the P VS NP Question: A New Proof of InequalityAngelo Raffaele MeoThe analysis discussed in this study is based on a well-known NP-complete problem which is called “satisfiability problem or SAT”. From SAT a new NP-complete problem derives, which is described by a Boolean function of the number n of the clauses of SAT called “core function”. In this study a new proof is presented according which the number of gates … …Journal of Computer Science, Vol. 17, Issue 5 · 27 May 2021 · 9,442 accessesView PDFCite

Research ArticleOpen accessIn the keywordsController Based Observer in Switched System with Norm Bounded UncertaintyMongi Besbes, Elyes MaherziProblem statement: This study discusses the robust stabilization of norm bounded discrete switched systems. Approach: The proposed method is using the second Lyapunov approach and the poly-quadratic function concept. The stabilization conditions are written through linear matrix inequality relations. The control law is based on a static output feedback with the use of a switched observer. The synthesis conditions of … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 11 May 2012 · 6,904 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTime Clustering of the Occurrence of Sleep ApneaNur Zakiah Mohd SaatProblem statement: In this study, the inequality of apnea rates during sleep was investigated. Approach: This study used a database comprising 13 patients with apnea problems. The data was extracted from the MIT-BIH database. The Lorenz curve and Gini index were used to determine the inequality of apnea rates. In order to test for cluster, random or regular patterns of … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 23 Sep 2011 · 6,858 accessesView PDFCite
