Research ArticleOpen accessIn the abstractTolerances 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
Research ArticleOpen accessIn the abstractTransverse Velocity, Transverse Boundary Shear Stress and Flow Deviation in Meandering Open ChannelsYoussef Ismail HafezThis study presents a novel approach for characterizing the mechanics of flow in mildly meandering open channels, specifically focusing on the development of a new vertical distribution equation for transverse velocity. Unlike existing equations in the literature that rely on complex logarithmic or integral forms or infinite series forms, which are impractical for hydraulic engineers, the proposed equation employs ordinary … …American Journal of Environmental Sciences, Vol. 20, Issue 1 · 25 Jul 2024 · 5,058 accessesView PDFCite
Research ArticleOpen accessIn the abstractInventory Models with Power Demand and Inventory-Induced Demand with Holding Cost FunctionsRakesh Prakash Tripathi, Sarla Pareek, Manjit KaurIn real life customers are motivated to buy more if there is more availability of product. In this study, we develop inventory model for inventory dependent demand with different holding cost function. Mathematical formulations are discussed for two situations i.e., power demand rate with inventory dependent holding cost functions and inventory-induced demand rate with time and inventory dependent holding cost … …American Journal of Applied Sciences, Vol. 14, Issue 6 · 6 Apr 2017 · 7,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractRobust Linear Discriminant AnalysisSharipah Soaad Syed Yahaya, Yai-Fung Lim, Hazlina Ali, Zurni OmarLinear Discriminant Analysis (LDA) is the most commonly employed method for classification. This method which creates a linear discriminant function yields optimal classification rule between two or more groups under the assumptions of normality and homoscedasticity (equal covariance matrices). However, the calculation of parametric LDA highly relies on the sample mean vectors and pooled sample covariance matrix which are sensitive … …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 4 Jan 2017 · 7,649 accessesView PDFCite
Research ArticleOpen accessIn the abstractConformal Mapping of Temperature Variation in Compost HeapJonah Chukwuemeka Agunwamba, Oji Achuka NwokeLaboratory in vessel trapezoidal compost system was designed and constructed. Temperature variation in the compost heap was measured for five days at various depths. Mathematical model for the variation of temperature of the composting process was developed using Conformal Mapping Technique. One of the parameters in the model had two distinct roots, one a positive root and the other negative … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 17 Jun 2016 · 7,347 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Influence of Local Wisdom on the Actualisation of Educative, Scientific and Religious Behaviour on anAcademic Environment in a UniversityEdi Suryadi, KusnendiThis paper examines the influence of local wisdom on academic environment in an Institution of higher education. The Sundanese values have been used as a case in point to examine how culture, scientific and religious values can influence educationwithin an academic society. In Sundanese culture, we find patterned intellectual and moral creativity which contains a system ofmoral values and norms … …American Journal of Applied Sciences, Vol. 13, Issue 4 · 2 May 2016 · 7,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractEconomic Order Quantity with Linearly Time Dependent Demand Rate and ShortagesR. P. Tripathi, D. Singh, Tushita MishraThis paper presents an inventory model with linearly time dependent rate and shortages under trade credits. We show that the total cost per unit is convex function of time. Some properties have also been discussed based an optimal solution. The results are discussed with the help of numerical examples. Sensitivity analyses with a variety of numerical results showing the effect … …Journal of Mathematics and Statistics, Vol. 11, Issue 1 · 26 Jun 2015 · 7,006 accessesView PDFCite

Perez-Rebollar et al.Leptin is a hormone that regulates energy balance. Since its discovery two decades ago, several efforts have been made to fully understand its role in metabolic regulation of feeding behavior, reproduction, glucose homeostasis, immune function, bone formation, lipid metabolism, among others. Its use as a therapeutic option in obese patients is still limited due to the syndrome known as Leptin … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 9 Jul 2014 · 7,386 accessesView PDFCite
Research ArticleOpen accessIn the abstractReligion and Schools in a Liquid WorldFrank PetersThis study is an exploration of the changing contexts within which schools are required to function. As global borders have become more porous schools are challenged to deal with students from increasingly diverse cultural, linguistic and religious backgrounds, frequently in a political context that is explicitly secular or nondenominational. This perspective may not be perceived by all to be as … …Journal of Social Sciences, Vol. 8, Issue 3 · 10 Aug 2012 · 7,624 accessesView PDFCite
