Research ArticleOpen accessAll words, across the recordObservational Study of Wind Shear in Northeastern BrazilFernando R. Martins, André R. Gonçalves, Enio B. PereiraThe wind energy share is growing fast in Brazil and a better understanding of wind speed vertical profiles is essential for accurate power density estimates. The wind shear is highly variable in space and time, being influenced by surface layer stability. Studies concerning wind vertical profiles may have a significant contribution to the Brazilian energy sector. However, wind observational data … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 12 Mar 2016 · 8,219 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEXPERIMENTAL MEASUREMENTS AND MODELING USING CESFAMBTM SOFTWARE OF THE PRODUCT GAS COMPONENTS ON THE 2MWTH GASIFIER PLANTI.V. Dyakov, G.V. Baron, S. Bram et al.The work assesses the performance of a prototype 2MWth plant as an auxiliary source of energy based on biomass gasification using wood pellets as a fuel. During steady operation, process temperature, process pressure and concentrations of components in the product gas have been measured the measurements are compared to the simulation results obtained with the CeSFaMBTM software. The underlying model … …Energy Research Journal, Vol. 5, Issue 1 · 1 Dec 2014 · 6,548 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordUSE OF COMPUTATIONAL FLUID DYNAMIC TO PREDICT AIRFLOW AND TEMPERATURE DISTRIBUTION IN A RESIDENTIAL BUILDING WITH AN UNDER FLOOR AIR DISTRIBUTION SYSTEMAbd Alnasser Almate A. Ali, Ahmed Cherif Megri, Paul A. Dellenback, Yao YuOur objective is to demonstrate the use of Computational Fluid Dynamic (CFD) in building applications. In particular, CFD has been used for temperature and airflow predictions of building spaces conditioned using Under Floor Air Distribution (UFAD) System. The space used is an instrumented laboratory room (old daycare center) located at the University of Wyoming. The use of the CFD simulation … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 11 Apr 2014 · 8,256 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAn Experimental Comparison Between Demand Systems of Major Food Groups in Urban EconomicsMahmoud Daneshvar Kakhki, Naser Shahnoushi, Fatemeh RezapourProblem statement: This study examined the eleven major food groups demand for urban areas of Iran during1361-1386. Approach: AIDS, ROTTERDAM, CBS and NBR models was compare together and Sur method was applied for estimating of systems, too. Results: Results of study showed cream and fresh fruits have smallest and largest income elasticity, respectively. Also, cream, bread, dairy, egg, fresh vegetables, … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 6,994 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Garcinia Atroviridis on Oxidative Stress and Atherosclerotic Changes in Experimental Guinea PigsAdel. A. Amran, Zaiton Zakaria, Faizah Othman, Paden MoratProblem statement: Oxidative stress plays a major role in hypercholesterolemia induced atherosclerosis. Garcinia atroviridis has been shown to exhibit antioxidant properties. Approach: The present study aimed to investigate the effect of Garcinia atroviridis on the oxidative stress in guinea pigs fed with high cholesterol diet. Twenty-four male Guinea pigs were divided into four groups. Group I served as control while … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 2 · 30 Jun 2010 · 9,038 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBackscattered Acoustic Energy by Monobubbles Experimental Approach and Statistical Study of the AttenuationAli Khelil, Claude ManteProblem statement: As the number of air bubbles in the sea is very high, they are so many acoustic diffusers who make illegible the recordings the purpose of which is to quantify the alive bodies. The signals backscattered by air bubbles constitute a parasite in offshore recordings and must be eliminated. It is planned to finalize techniques allowing the localization … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,585 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExperimental Investigation on Geomechanical Properties of Tropical Organic Soils and PeatBujang B.K. Huat, Afshin Asadi, Sina KazemianProblem statement: Organic soils and peat were believed to be geotechnically problematic due to their very high compressibility, very low shear strength and difficult accessibility. Although conventional soil mechanics theory could be applied to the soils, it was found that important anomalies existed which required special considerations. Correlations between geomechanical parameters for the soils were known to be important for … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 10,177 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAn Experimental Study of Petty Corrupt Behaviour in Small Decision Making ProblemsTakemi FujikawaThis research discusses small decision making problems and petty corruption as their practical applications with a structured economic experiment. One of examples of petty corruption considered includes demands for petty bribes by traffic officials followed by police. We examine that it is caused by subjective underweighting of rare events and its objective probabilities. This literature reports results of an experiment, … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 3 Dec 2005 · 8,108 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordImpact of the Edges of a Backside Diffusive Reflector on the External Quantum Efficiency of Luminescent Solar Concentrators: Experimental and Computational ApproachMauro Pravettoni, Cristina S. Polo Lòpez, Robert P. KennyLuminescent Solar Concentrators (LSCs) have been proposed in the 1970s as cheap planar concentrators for residential applications and nowadays represent a novel idea with excellent perspectives for building integration photovoltaics. The interest in LSCs has increased in the last years, due to improved stability of luminescent dyes, the introduction of quantum dots and nanorods and the overall reported increase in … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 18 Jan 2016 · 8,368 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExperimental Evaluation of the Raking Energy in Damping System of Steel Stud Partition WallsSalah Amer, Sameer Hamoush, Taher M. Abu-LebdehNonstructural partition walls are usually specified based on the best practice without any structural design calculations. However, given the likely severe earthquake damage to nonstructural components and the substantial cost of repair to such components, it is imperative that we develop an understanding of the seismic response of the nonstructural partition walls when subjected to earthquake loading conditions. The main … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 6 Nov 2015 · 7,644 accessesView PDFCite
