Research ArticleOpen accessIn the keywordsIntervention Model for Analyzing the Impact of Terrorism to Tourism IndustryZ. Ismail, Suhartono, A. Yahaya, R. EfendiProblem statement: It is common in time series data with extreme change in its mean caused by an intervention which comes from external and/or internal factors. This extreme change in mean is known as regime change or structural change. Problems of external factor intervention such as the effect of the Arab oil embargo to consumption level of electricity in United … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,949 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Efficient Algorithm for Capacitated Multifacility Location ProblemsChansiri Singhtaun, Peerayuth CharnsethikulIn this paper, a squared-Euclidean distance multifacility location problem with inseparable demands under balanced transportation constraints is analyzed. Using calculus to project the problem onto the space of allocation variables, the problem becomes minimizing concave quadratic integer programming problem. The algorithm based on extreme point ranking method combining with logical techniques is developed. The numerical experiments are randomly generated to … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,443 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStructure of a Photovoltaic Electric LocomotiveFlorian Ion Tiberiu PetrescuThe paper proposes to start studies at the global level for the implementation of photovoltaic electric locomotives. The question the author asks is why such trains have not been implemented so far, is there no interest in such a thing? This may avoid the current rush to implement 5G technologies in an already extremely dangerous form for humanity, the rush … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 16 Nov 2019 · 7,196 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEnhancing Social Media Face Emotion Recognition Using a Fuzzy ELM ApproachShuchi Gupta, K. Viswanath, S. Gokul Pran et al.Our computational tools for searching, exploring, and sharing personal photographs are falling behind the rapid pace at which these images are being captured digitally. The use of automatic face recognition to categorize images according to the people in them is one potential solution. Accurate recognition on the Internet scale, however, presents the seemingly insurmountable challenge of picking out specific people … …Journal of Computer Science, Vol. 22, Issue 3 · 20 Mar 2026 · 1,991 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Inverse Weibull Distribution: Properties and ApplicationsMona Mustafa Elbiely, Haitham M. YousofIn this work, we introduce a new flexible extension of the Inverse Weibull distribution. Some important mathematical properties of the proposed model are derived along with a numerical analysis of mean, variance, skewness and kurtosis measures of the proposed model. The performance of the maximum likelihood method is assesses via a comprehensive simulation studies in terms of mean squared errors. … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 25 Mar 2019 · 7,509 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRiver Flow Conditions and Dynamic State Analysis of Pahang RiverMuhamad Barzani Gasim, M. E. Toriman, Mushrifah Idris et al.Pahang River (Sg. Pahang) is the longest river in Peninsular Malaysia. Flood is a common event in Pahang River Basin during wet season which triggered by monsoon season. The hydrodynamic study of Pahang River should be well understood especially when it is a target of northeast monsoon which influenced the Pahang River Basin every year (from November to March). 17 … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 10 Jan 2013 · 8,709 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOn Quasi E-Convex Bilevel Programming ProblemE. A. Youness, O. M.A. Al-OlaaBilevel programming problems involve two optimization problems where the data of the first one is implicity determined by the solution of the second. This study introduces the notions of E-convexity and quasi E-convexity in bilevel programming problems to generalize quasi convex bilevel programming problems. …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,574 accessesView PDFCite
