Research ArticleOpen accessEvery word in the titleEvaluation of Biogas Plants by the Application of an Internal Rate of Return and Debt Service Coverage ApproachGiuseppe Bonazzi, Mattia IottiEnergy production using renewable energy has an effect on environmental sustainability and on public expenditure. In fact, this industry is heavily assisted by public support from the European Union and the Italian State. Developing and applying a method to evaluate the return on investment for companies operating in the field of renewable energy allows them to quantify their efficient use … …American Journal of Environmental Sciences, Vol. 11, Issue 1 · 6 Apr 2015 · 7,637 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTHROUGHPUT AND BIT ERROR RATE ANALYSIS OF LUBY TRANSFORM CODES WITH LOW AND MEDIUM NODAL DEGREE DISTRIBUTIONSI. Joe Louis Paul, S. Radha, J. RajaThis study presents two degree distributions namely low and medium nodal degree distributions aiming to build a low overhead Luby Transform (LT) codes. The motivation is to design a fast encoder/decoder especially for real-time multimedia streaming and multicasting applications using LT codes. The key idea of this study is to restrict the average degree of the transmitted encoded symbols as … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 12 Aug 2014 · 6,617 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA JUMP-DIFFUSION WITH STOCHASTIC VOLATILITY AND INTEREST RATEPairote Sattayatham, Paiboon PeeraparpIn this study, we present the application of Time Changed Levy method to model a jump-diffusion process with stochastic volatility and stochastic interest rate. We apply the Lewis Fourier transform method as well as the risk neutral expectation pricing method to derive a formula for a European option pricing. These combining methods give quite a short route to derive the … …Journal of Mathematics and Statistics, Vol. 9, Issue 1 · 27 Mar 2013 · 6,891 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCorn Response to Nitrogen Timing and Rate under Strip Tillage and Low-Yield Environment in Southeastern Coastal PlainsPawel Wiatrak, Ahmad Khalilian, Guihua ChenProblem statement: Insufficient rainfall under low yield environment may affect nitrogen management, plant growth indices and grain yields of corn (Zea mays L.). Approach: The objective of this study was to determine the effects of two N application timings (all at planting and as split application with N applied at planting and V6 stage) and five N fertilizer rates (0, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 10 Mar 2011 · 7,994 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Novel Low-Power CMOS Operational Amplifier with High Slew Rate and High Common-Mode Rejection RatioIsmail Nabhan, Moussa AbdallahProblem statement: High speed operational amplifier is always an on-going research topic since major high speed application are needed. Approach: A two-stage operational amplifier (op amp) is designed, simulated and fabricated using a UMC 0.5 μm 2P2M CMOS technology. Results: This chip includes a compensation technique to ensure stability and zero systematic input-offset-voltage. The fabricated chip achieves a 84 dB … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,241 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Oxygenated Gasoline on Fuel and Air Mass Flow Rates and Air-Fuel RatioWaleed Momani, Suleiman Abu-Ein, Montaser Momani, Sayel M. FayyadThe effects of excess feeding oxygen to the fuel-air mixture on air and fuel mass flow rates and also on air-fuel ratio are investigated here experimentally. This study concerned with the effects of injecting pure oxygen quantity to the mixture of fuel and air before interring the combustion chambers. It is found that the mass flow rate of fuel with … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,370 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effect of Acute Administration of Artemisia Persia Extracts on Arterial Blood Pressure and Heart Rate in RatsFarzaneh Esmaeili, Gholamreza Sepehri, Ghollam-Reza Moshtaghi-Kashanian et al.Problem statement: Artemisia Persia (AP) used for its therapeutic effects in folk medicine whiles some species of Artemisia shown a hypotensive effect. To determine the cardiovascular effect of AP, we tested the pharmacological responses of aqueous and methanolic extracts of AP on blood pressure (BP) and Heart Rate (HR) of normotensive and ephedrine induced hypertensive rats using a tail-cuff computerized … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,659 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRecent Sedimentation Rate and Sediment Ages Determination of Kemaman-Chukai Mangrove Forest, Terengganu, MalaysiaB.Y. Kamaruzzaman, M.C. OngTwo 20 cm sediment cores were collected with a D-section corer in the Kemaman-Chukai mangrove forest and analyzed for 210Pbex (excess 210Pb) in order to understand the sedimentation pattern. The activities of 210Pb along with the 208Po tracer were measured by Alpha Spectrometry on a silicon surface barrier detector connected to a multi channel analyzer. Sedimentation rates were determined applying … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 9,305 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEarthquake Risk Management Strategy Plan Using Nonparametric Estimation of Hazard RateAflaton Amiri, Ramin TabatabaeiEarthquake risk is defined as the product of hazard and vulnerability studies. The main aims of earthquake risk management are to make plans and apply those for reducing human losses and protect properties from earthquake hazards. Natural risk managers are studying to identify and manage the risk from an earthquake for highly populated urban areas. They want to put some … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,745 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetermining the Hazardous Medical Waste Generation Rates of Private Health Care Facilities-Case Study from Dhaka City of BangladeshMd. Yousuf Rumi, Rezaul KarimMany developing countries are lagging behind the developed countries to properly manage their hazardous healthcare waste.
