Research ArticleOpen accessIn the abstractAn Investigation of Thermal Characteristics of a Sintered-Wick Heat Pipe with Double Heat SourcesNattawut Tharawadee, Pradit Terdtoon, Niti Kammuang-lueHeat pipes have been used extensively in the electronic industry for decades especially in laptop computers. For cost-effectiveness, a single heat pipe is designed to simultaneously transfer heat from both the Central Processing Unit (CPU) and the Graphics Processing Unit (GPU) inside the main board to the heat sink. This causes the efficiency of the heat pipe to change without … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,229 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Efficiency Investigation on Heat Recovery System Used in a Solar-Powered Desalination ProcessAouatef Rachdi, Louy Qoaider, Mahmoud Ben-Amara, AmenAllah GuizaniThe aim of this work is to experimentally study, the effect of the heat recovery on water production in a solar desalination process that is working with multiple stage humidification technique. The water production, the temperature and the humidity were tested for such a pilot plant, which operates without and with a heat recovery system. The humidifier efficiency increases with … …Energy Research Journal, Vol. 3, Issue 2 · 11 Mar 2013 · 7,264 accessesView PDFCite
Research ArticleOpen accessIn the abstractGaseous Emissions and Combustion Efficiency Analysis of Hydrogen-Diesel Dual Fuel Engine under Fuel-Lean ConditionPrateep Chaisermtawan, Sompop Jarungthammachote, Sathaporn Chuepeng, Thanya KiatiwatExhaust gas emissions from diesel engine combustion using alternative fuel may change in their quantities that can affect exhaust gas after-treatment devices and environmental ambient. This study presents theoretical analysis of combustion generated emissions and efficiency of hydrogen-diesel duel fuel in fuel-lean condition. A chemical equilibrium method by minimizing Gibbs free energy is employed to estimate exhaust gas products from … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 1 Sep 2012 · 7,509 accessesView PDFCite
Research ArticleOpen accessIn the abstractArtificial Neural Network Based Rotor Capacitive Reactance Control for Energy Efficient Wound Rotor Induction MotorK. Ranjith Kumar, S. Palaniswami, K. Siva KumarProblem statement: The Rotor reactance control by inclusion of external capacitance in the rotor circuit has been in recent research for improving the performances of Wound Rotor Induction Motor (WRIM). The rotor capacitive reactance is adjusted such that for any desired load torque the efficiency of the WRIM is maximized. The rotor external capacitance can be controlled using a dynamic … …Journal of Computer Science, Vol. 8, Issue 7 · 26 May 2012 · 7,162 accessesView PDFCite
Research ArticleOpen accessIn the abstractMinority Serving College and University Cost EfficienciesG. Thomas SavProblem statement: Higher education minority enrollment growth has far outstripped white non-minority growth in the United States. Minority serving colleges and universities have disproportionately attended to that growth and will continue to play a critical role in providing minority educational opportunities in a knowledge based and globally diverse economy. However, they will face new and challenging budgetary and managerial reforms … …Journal of Social Sciences, Vol. 8, Issue 1 · 21 Jan 2012 · 7,843 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeveloping the Environment of Information Technology Education using Cloud Computing InfrastructureChen-Feng Wu, Liang-Pang HuangThe education of Information Technology (IT) in Taiwan has been promoted since 1997. However, there were still problems with the current environment of IT education. Problem statement: The major problem was that students were unable to practice after school with the same environment and there was no appropriate space to save their files for students, so it was not convenient … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 1 Aug 2011 · 7,652 accessesView PDFCite
Research ArticleOpen accessIn the abstractBanking Efficiency in Lebanon: An Empirical InvestigationMouataz Zreika, Nasser ElkanjProblem statement: The main goal behind this study is to identify whether banks are working at full efficiency or not and spot the changes in efficiency for banks operating in Lebanon after 2007 financial crisis. Approach: This study was conducted to examine the technical efficiency of 40 banks operating in Lebanon over the two sub-periods 2002-2006 and 2006-2009 using Data … …Journal of Social Sciences, Vol. 7, Issue 2 · 12 Feb 2011 · 8,297 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Comprehensive Computer Program for Predicting Farm EnergyS.A. Al-Hamed, S.A. Al-Suhaibani, F.S. Mohammad, M.F.I. WahbyProblem statement: The agricultural industry is a major user of energy. Energy is used directly for operating agricultural machinery and equipment on the farm and indirectly in the manufacturing of fertilizers and pesticides and processing of agricultural products off the farm. In order to reduce the cost of agricultural production, energy uses on the farm must be identified and optimized … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,061 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Model of Double Pass Photovoltaic Thermal Air Collector with FinsEbrahim M. Ali Alfegi, Kamaruzzaman Sopian, Mohd Yusof Hj Othman, Baharudin Bin YatimProblem statement: The efficiency of photovoltaic cells is generally temperature dependent (efficiency decrease when the temperature of the photovoltaic cells increase). This problem can be solved by cooling the solar cells during operation and operated at low temperature. Approach: This study presented a numerical model of double pass Photovoltaic Thermal (PV/T) solar air collector with fins attached to the back … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 8,006 accessesView PDFCite
