Research ArticleOpen accessIn the abstractA New Weighted Rank CorrelationTahani A. Maturi, Ezz H. AbdelfattahProblem Statement: There have been many cases in real life where two independent sources have ranked n objects, with the interest focused on agreement in the top rankings. Spearman's rho and Kendall's tau coefficients assigned equal weights to all rankings. As a result, the literature proposed several weighted correlation coefficients with emphasis on the top rankings, including the top-down, weighted … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 8,826 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuzzy Based Digital Automatic Voltage Regulator of a Synchronous Generator with Unbalanced LoadsA. Darabi, S.A. Soleamani, A. HassanniaVoltage stability and power quality of the electrical systems depend on proper operation of the Automatic Voltage Regulators (AVR) of generators. Nowadays, design technology of the AVRs is being broadly improved. According to wide range operating conditions of the generators and loads, the fuzzy AVRs are going to be the modern type of regulators, particularly, for the genset alternators operating … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,602 accessesView PDFCite

EditorialOpen accessIn the abstractON THE CHALLENGES OF THE USE AND INTEGRATION OF RENEWABLE ENERGY SOURCESMariano MartínOverview: Although renewable energy sources are plentiful, their availability is highly volatile in time and distributed across regions while and the processes that transform them into useful power or chemicals are underdeveloped. In this work we discuss on the scope for the use and integration of renewable energy sources and the future development of the alternatives. Energy, the sources and … …Energy Research Journal, Vol. 5, Issue 1 · 11 Sep 2014 · 7,540 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Wireless Sensor Network Channel in Agricultural ApplicationNaseer Sabri, S. A. Aljunid, R. B. Ahmad et al.Problem statement: In this study, the behavior of small scale fading channel due to a moving sink node of a Wireless Sensor Network (WSN) or moving of surrounding objects is presented. Approach: Specifically, this research introduces the effects of multipath and scattering on the transmitted signal due to mobile sink node within forest or closed field filled of reflectors and … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 24 Nov 2011 · 7,096 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of the Cuttings Cleaning During the Drilling OperationHussain H. Al-Kayiem, Nadia Mohd Zaki, Muhamad Z. Asyraf, Mahir Elya ElfeelProblem statement: Oil well cleaning is the ability of a drilling fluid to suspend and transport drilled cuttings from the down hole (bit face) to the surface. The cleaning performance was affected by many factors such as fluid viscosity, annular flow velocity, angle of inclination and drill cuttings size and shape and. Approach: Navier-Stoke equations, the continuity equation and the … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,249 accessesView PDFCite

Research ArticleOpen accessIn the abstractSeparation, Purification and Anti-aging Activity of Tobacco PolysaccharidesMengyue Huang, Jingwu Song, Shuaishuai Chang et al.To separate tobacco polysaccharides and investigate their antioxidant and anti-aging properties, crude tobacco polysaccharides were extracted from raw tobacco using hot water, followed by purification through DEAE-52 cellulose column chromatography. The molecular weight and monosaccharide composition of the isolated polysaccharides were analyzed using HPGPC and HPLC. The antioxidant activities of these tobacco polysaccharides were tested using DPPH, ABTS, hydroxyl radicals … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 15 Jan 2025 · 5,103 accessesView PDFCite
Review ArticleOpen accessIn the abstractThe Yield of the Thermal EnginesNicolae Petrescu, Florian Ion Tiberiu PetrescuThis paper presents an algorithm for determining the dynamic parameters of the main classic mechanism of internal combustion engines. It shows the distribution of forces (on the main engine mechanism) to internal combustion engines. With these forces and together with the kinematic coupling speeds, the efficiency of the thermal engine is determined. The method applies separately for two distinct situations: … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 14 May 2019 · 6,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Analysis of Bipolar Plate for 500w Pem Fuel Cell StackA. Kalaiyarasan, C. Srinivasan, S. SundaramThe PEM Fuel Cell (PEMFC) performance depends on the operating parameters like temperature, pressure, stoichiometric ratio of reactants, relative humidity, back pressure on anode and cathode flow channels, and the design parameters like rib width to channel width (L:C), channel depth, shape of the flow channel and number of pass on the flow channel. The voltage and power produced by … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 13 Jan 2018 · 7,895 accessesView PDFCite
