Research ArticleOpen accessIn the abstractEnvironmental Pollution Assessment of Different Diesel Injector Location Of Direct-Injection Diesel Engines: Theoretical StudyEyad S. M. Abu-Nameh, Jehad A. A. YaminAn Analytical investigation on the effect of injector location of a four-stroke DI diesel engine on its pollutants’ emissions was carried out under different injector locations ranging from central to peripheral at different engine speeds ranging from 1000 rpm to 3000 rpm. The simulation results clearly indicated the advantages and disadvantages of the central location over the peripheral one. It … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 6,471 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEmpirical Analysis: Business Cycles and Inward FDI in ChinaQiyun Fang, Yao LiuIt is well-known that the current speeding-up of globalization has been, on one hand, spreading macro economic effects around the world, while, on the other, fueling firms' activities of crossing national borders. Then, are there any links between these two influences? In this paper, we chose China as our subject, to try to clarify it. A set of models for … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 6,836 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCombustion Analysis of a CI Engine Performance Using Waste Cooking Biodiesel Fuel with an Artificial Neural Network AidGholamhassan NAJAFI, Barat GHOBADIAN, Talal F. YUSAF, Hadi RAHIMIA comprehensive combustion analysis has been conducted to evaluate the performance of a commercial DI engine, water cooled two cylinders, in-line, naturally aspirated, RD270 Ruggerini diesel engine using waste vegetable cooking oil as an alternative fuel. In order to compare the brake power and the torques values of the engine, it has been tested under same operating conditions with diesel … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 8,196 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPacked Forest Chart ParserQi Haoliang, Li Sheng, Yang Muyun, Zhao TiejunPacked forest chart parser, like the traditional chart parsing algorithm, uses charts to store all the information produced while parsing to avoid redundant works. Its advantage over the traditional chart parser was the packed forest representation. The algorithm not only shares the non-terminal categories as what was done in the shared parse forest, but also shares the leftmost common elements. … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 6,561 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDynamical Properties Analysis of Frictional Winding Mechanism with Bobbin Elastic SupportMohammed A. Alnawafleh, Faisal M. Al-GhathianA mathematical model of the Frictional Winding Mechanism (FWM) with bobbin elastic supports for a search of optimal structural and physical parameters for developing new and updating existing FWMs has been carried out. The model was derived from bobbin equipped with pendulum suspension for forming cylinder shaped packages. In the derivation method it was considered that the model corresponds the … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,886 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSolving Linear Programming Problems on the Parallel Virtual Machine EnvironmentJrJung Lyu, Hsing Luh, Ming-Chang LeeThis study developed a parallel algorithm to efficiently solve linear programming models. The proposed algorithm utilizes the Dantzig-Wolfe Decomposition Principle and can be easily implemented in a general distributed computing environment. The analytical performance of the well-known method, including the speedup upper bound and lower bound limits, was derived. Numerical experiments are also provided in order to verify the complexity … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 7,841 accessesView PDF Cite
