Research ArticleOpen accessEvery word in the titleStatistical Modelling of Botswana’s Monthly Maximum Wind Speed using a Four-Parameter Kappa DistributionOliver Moses, Bhagabat Prasad ParidaWind speed modelling has been key to many environmental and engineering applications, particularly in environmentally friendly wind power generation to meet energy demands. Efficient assessment of wind speed at different recurrence intervals requires the choice of a suitable statistical distribution and an unbiased method of parameter estimation. This study suggests the use of a four parameter Kappa distribution, with its … …American Journal of Applied Sciences, Vol. 13, Issue 6 · 22 Jun 2016 · 7,546 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleParameter Settings for New Generational Genetic Algorithms for Solving Global Optimization ProblemsSiew Mooi Lim, Md. Nasir Sulaiman, Norwati Mustapha, Abu Bakar Md. SultanThis study operates within experimental design with two main tools of Taguchi method namely orthogonal array and signal to noise ratio to discover the optimal parameter settings for newly proposed generational genetic algorithms; they are Laplace Crossover-Scale Truncated Pareto Mutation (LX-STPM) and Rayleigh Crossover-Scale Truncated Pareto Mutation (RX-STPM). It concluded that GA parameter settings are algorithms and problems dependent. …Journal of Computer Science, Vol. 11, Issue 11 · 7 Jan 2016 · 6,404 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleON THE ABSENCE OF ANTIMATTER FROM THE UNIVERSE, DARK MATTER, THE FINE STRUCTURE PARAMETER, THE FLUCTUATIONS OF THE COSMIC MICROWAVE BACKGROUND RADIATION AND THE TEMPERATURE DIFFERENCE BETWEEN THE NORTHERN AND SOUTHERN HEMISPHERE OF THE UNIVERSEEmmanuil ManousosThe theory of selfvariations correlates five cosmological observations considered to be unrelated by the physical theories of the previous century. The absence of antimatter from the Universe, the Dark Matter, the slight variation of the fine structure parameter, the temperature fluctuations of the cosmic microwave background radiation and the temperature difference between the northern and southern hemisphere of the Universe … …Physics International, Vol. 5, Issue 1 · 28 Nov 2014 · 8,881 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGenerator Dynamic Performance Affected by Parameter’s UncertaintyAkbar Beik Khormizi, Mohammad Reza Aghamohammadi, Mina RezaeeThis study investigates the effect of generator parameters inaccuracy on the transient stability performance of generator and power system. Normally, generator parameters are identified either by calculation based on design specification or by measurements. In both approaches the parameters are obtained with some degree of inaccuracy. Inaccuracy and uncertainty in the obtained parameters can affect the dynamic performance and transient … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 8 Jun 2013 · 6,630 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Development of Parameter Estimation on Hazard Rate of Trivariate Weibull DistributionIrfan Wahyudi, Purhadi, Irhamah, SutiknoIn this study, the interrelation concepts of trivariate distribution function, trivariate survival function, trivariate probability density function and trivariate hazard rate function of trivariate Weibull distribution are presented. The goal of this contribution is to estimate the trivariate Weibull hazard rate parameters. To reach this goal, we will use an analitical approach in estimating called the Maximum Likelihood Estimation (MLE) … …Current Research in Biostatistics, Vol. 2, Issue 2 · 11 Aug 2012 · 8,923 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCross-Layer Design for Reducing the Energy Consumption based on Mobility Parameter in DSR for Mobile Ad-Hoc NetworkV. Bhanumathi, R. DhanasekaranProblem statement: The main idea is to design an energy efficient algorithm for reducing the amount of overhearing based on RSS value in a Mobile Ad-hoc Network (MANET). Approach: A cross layer framework is designed by combining the physical, MAC and network layer. RSS value is taken from the physical layer and it is used for finding the Mobility Parameter … …Journal of Computer Science, Vol. 8, Issue 4 · 28 Jan 2012 · 6,814 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleElectronegativity, Interaction Parameter and Electronicpolarizability for Bisumth Borate Metal GlassesEl-Sayed Moustafa, Farid ElkhatebProblem statement: In the present work, we applied the concept of the optical electronegativity to predict basic properties of some ternary oxide glasses. Recently Optical electronegativity of many binary oxide glasses has been evaluated on the basis of two different parameters, the linear refractive index and the energy gap, which have demonstrated remarkable correlation. Approach: In this study, the refractive … …Physics International, Vol. 2, Issue 1 · 1 Dec 2011 · 7,312 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimization of Hydraulic Parameters of Iranshahr Alluvial AquiferJafar Rahnama-Rad, Mohammad Yaghoub Bavali, Reza DerakhshaniProblem statement: The Iranshahr aquifer consists of an unconfined layer. We simulated groundwater flow of the Iranshahr aquifer in a conceptual model. This model is a suitable tool for management of groundwater system and would also be effective when applied in other countries. Approach: In this study, we constructed the conceptual model of Iranshahr aquifer, which is important and applicable … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,539 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleLippia multiflora (Verbenacae, Mold.) Leaves Dietary Supplementation Effect on Broiler Chickens’ Growth, Hematological Parameters, and Serum BiochemistryKelemin Awa Koné, Tagouèlbè Tiho, Yapo Magloire Yapi, Vama Etienne TiaThe continued overuse of synthetic antibiotics has led to microbial resistance, responsible for numerous therapeutic failures in both animal and human health. This resistance has prompted the search for natural alternatives to the use of synthetic antibiotics in the poultry sector. The essay evaluated Lippia multiflora (Lm) leaves’ effects on chickens’ growth, health, and fatty acid profile.
