Research ArticleOpen accessPhrase in the titlePerformance Evaluation of Channel Propagation Models and Developed Model for Mobile CommunicationYahia ZakariaPropagation models represent a solidifying of mathematical equations and algorithms that are used for radio signal propagation prediction in specific regions. In this research different propagation models are analyzed and compared. These propagation models have been proposed at the operating frequency of 3.8 GHz for different transmitter antenna heights in all types of terrain. These propagation models depend on location, … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 25 Feb 2017 · 8,409 accessesView PDFCite

Research ArticleOpen accessPhrase in the titlePerformance Evaluation of an Oxidation Ditch System with a Disc AeratorAbdel Ghaly, Ashley ThistleProblem statement: The oxidation ditch system has been used to treat various types of wastewaters. Several types of aerators are used to supply the treatment process with oxygen. Among these devices, the disc aerator has certain advantages regarding foam generation over the brush and paddle type rotors, but the main disadvantages of this aerator is the limited oxygenation capacity. The … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 8,113 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCombining ANP and TOPSIS Concepts for Evaluation the Performance of Property-Liability Insurance CompaniesHui-Yin Tsai, Bao-Huey Huang, An Siou WangThis is a significant problem for the property-liability insurance industry. The study first uses Modified Delphi Method to sift influence property-liability insurance effects out norms. Moreover, the evaluation weights are determined using Analytic Network Process (ANP). Finally, the technique for ordering preference by similarity to the ideal solution (TOPSIS) constructs performance evaluation model of property-liability insurance companies in Taiwan. This … …Journal of Social Sciences, Vol. 4, Issue 1 · 31 Mar 2008 · 8,204 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Liquefaction Return Period for Bangalore Based on Standard Penetration Test Data: Performance Based ApproachK. S. Vipin, T. G. SitharamProblem statement: The conventional liquefaction evaluation is based on a deterministic approach. However in this method the uncertainty in the earthquake loading is not properly taken into account. However recent research in this field indicates that this uncertainty in the earthquake loading has to be considered in the liquefaction potential evaluation. Moreover the evaluation of liquefaction return period is not … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 7,741 accessesView PDFCite
