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 · 18,430 accessesView PDFCite
Review ArticleOpen accessIn the keywordsThe Influence of Bedding Application in Feedlot Cattle: A ReviewDathan Thomas Smerchek, Zachary Kidd Foster SmithA sizable portion of cattle on feed in the United States are fed in the Upper Midwest and Northern Plains region where temperatures routinely fall below freezing during late fall, winter and early spring. The persistent cold temperatures coupled with snow accumulation, wind, moisture and ice can cause undesirable pen conditions for confined cattle, ultimately resulting in decreased insulative capacity … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 23 Feb 2021 · 6,721 accessesView PDFCite

LooProblem statement: The proliferation of mobile phone use among the youths worldwide has sparked the interest of many researchers, especially those related to the mobile phone adoptions and use. However, there is a lack of study in assessing the impact of the mobile design on its users, especially in relation to the Short Messaging Service application. Due to this, an … …Journal of Social Sciences, Vol. 7, Issue 2 · 21 Mar 2011 · 7,872 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNonparametric Analysis on System Availability: Confidence Bound and Power FunctionJau-Chuan Ke, Yunn-Kuang ChuIn this study we consider the steady-state availability, denoted A, of a system with distribution-free failure and repair time. In particular, we are interested in constructing a lower confidence bound and a testing framework for A. We first show that the natural estimator  of A, defined as the ratio of the failure time sample mean to the sum of … …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 6,696 accessesView PDFCite
Literature ReviewOpen accessIn the keywordsIntracranial Atherosclerotic Disease: Treatment Potential and Diagnostic OpportunitiesAnastasia Vladimirovna Poznyak, Victoria Alexandrovna Khotina, Anton Yuvenalievich Postnov et al.Atherosclerosis, characterized by the accumulation of atherosclerotic plaques within large arteries, substantially increases the risk of cardiovascular events, including ischemic stroke. Intracranial atherosclerotic disease (ICAD) represents a particularly significant clinical threat given its strong association with ischemic stroke across multiple intracranial arterial territories. This review provides a comprehensive analysis of the pathogenesis, diagnosis, and management of intracranial atherosclerosis. Special attention … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 5 May 2026 · 1,096 accessesView PDFCite

Research ArticleOpen accessIn the keywordsClassification of Textures by Avoiding Complex PatternsV. V. Kumar, B. E. Reddy, U. S.N. Raju, A. SureshThe present research advocates a new method for texture classification based on primitive patterns. For this, an optimal set of eight simple patterns are selected based on their discrimination. The percentage of frequency of occurrences is computed for these patterns on entire texture image. Textures can be classified by using frequency of occurrences, for complex patterns also. The present research … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 6,976 accessesView PDFCite

It has been suggested that statins appear to have therapeutic benefits in diseases that are unrelated to elevated serum cholesterol levels. The aim of this study was to evaluation the effect of intraperitoneally injection of different doses of … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 4 · 11 Jan 2012 · 7,511 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSingularity Analysis of a Hybrid Serial-Cable Driven Planar RobotSamir Lahouar, Lotfi RomdhaneIn this study, we address the problem of singularities of a hybrid serial-cable driven planar robot. Based on an analytical kinetostatic analysis three types of singularities are determined, i.e., serial, parallel, and combined singularities. In addition, cable tensions should be positive, otherwise, the robot will be uncontrollable. The serial singularity corresponds to positions where the serial port of the robot … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 3 · 26 Sep 2022 · 5,610 accessesView PDFCite
