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 · 7,101 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of Palm oil Biodiesel Blends as a Fuel for Compression Ignition EngineB. Deepanraj, C. Dhanesh, R. Senthil et al.Problem statement: The increasing awareness of the environmental hazards and the alarming levels of air pollution have led to more restrictive regulations on engines emission control in recent years. Approach: The dwindling resources and rising cost of crude oil had resulted in an intensified search for alternate fuels. In the present study biodiesel (palm oil methyl ester) blends with diesel … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 7 Oct 2011 · 8,222 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Air Pollution on Human Health: Focusing on the Rudnyi Altay Industrial AreaVitaliy G. Salnikov, Marat A. KaratayevProblem statement: Air pollution in Kazakhstan is significant environmental problem. The air pollution level of cities and industrial centers remains rather high. The highest level of air pollution is registered in Ridder, Ust-Kamenogorsk, Almaty, Zyryanovsk, Aktau, Atyrau, Shymkent, Taraz, Petropavlovsk and Temirtau. The enterprises of the Rudnyi Altay, Pavlodar Oblast and enterprises of oil and gas complex in West-Kazakhstan, Atyrau … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 21 Jul 2011 · 10,451 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Socially Responsible Investment Markets (SRI) Using Dynamic Conditional Correlation (DCC) Method: Implications for DiversificationGurudeo Anand Tularam, Eduardo Roca, Victor Siew Howe WongProblem statement: Over the last ten years there has been a phenomenal growth in the amount of funds placed in SRI globally estimated to be around US$6.5 trillion while around US$55 billion in the Australian market. Accurate knowledge of correlation of the Australian SRI market with other SRI markets overseas is crucially important for Australian (SRI) investors for international portfolio … …Journal of Mathematics and Statistics, Vol. 6, Issue 4 · 4 Nov 2010 · 16,240 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Process Parameters on Electrical Discharge Machined Job Surface IntegrityA.K.M. Asif Iqbal, Ahsan Ali KhanProblem statement: Electrical Discharge Machining (EDM) is the most widely used non conventional machining process for removing material from workpiece by means of a series of repeated electric discharges. Electrical Discharge milling (ED-milling) is an emerging technology where a cylindrical tool electrode follows a programmed path in order to obtain the desired shape of a part. During machining of metals … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,591 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Replenishing Items with Seasonal Intermittent DemandGary Mitchell, Meike NiederhausenProblem statement: There are numerous difficulties associated with replenishing intermittent demand items and these are compounded when the demand distribution(s) vary seasonally. Excess inventories during an “off” season are typical, while shortages frequently occur during the “in” season, especially at the transition points between “seasons”. Approach: Evaluate the extent to which items characterized by non-stationary (seasonal) intermittent demand can be … …American Journal of Economics and Business Administration, Vol. 2, Issue 1 · 31 Mar 2010 · 7,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimplification of Sun Tracking Mode to Gain High Concentration Solar EnergyOmar Aliman, Ismail Daut, Muzamir Isa, Mohd Rafi AdzmanPower conversion from solar thermal energy to electrical energy is still very cost-intensive. Serious effort has to be given in the development of the concentrator or heliostat structure expenditure which contributing the most expensive component in a central receiver solar power plant. With current development to find alternatives and lower down the capital, a new mode of sun tracking has … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,190 accessesView PDFCite
Research ArticleOpen accessIn the abstractInverse Correlations for Multiple Time Series and Gaussian Random Fields and Measures of Their Linear DeterminismR.J. Bhansali, L. IppolitiFor a discrete-time vector linear stationary process, {X(t)}, admitting forward and backward autoregressive representations, the variance matrix of an optimal linear interpolator of X(t), based on a knowledge of {X(t-j), j≠0}, is known to be given by Ri(0)-1 where Ri(0) denotes the inverse variance of the process. Let A=Is-1Ri(0)ˉ1R(0)ˉ1, where R(0) denotes the variance matrix of {X(t)} and Is an … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,428 accessesView PDFCite
Research ArticleOpen accessIn the abstractRevisiting the Unit Root Hypothesis and Structural Break: Asia and Emerging Economies Foreign Exchange MarketsChristopher Gan, Sirimon Treepongkaruna, Hue Hwa Au YongThis study examines the stationary of ten Asian and for emerging Foreign Exchange (FX) rates during the 1990s.
