Research ArticleOpen accessIn the abstractControl of Incoming H2/O2 Flows in a PEM Fuel CellDhia Mzoughi, Nabila Khili, Hatem Allagui, Abdelkader MamiIt has become crucial, with the dwindling of energy resources related to the depletion risk of fossil and fissile resources, to find energy alternatives which have the same properties as those of a hydrocarbon in terms of transport and storage. In this context, the fuel cell appears as a very serious element both at the industrial and research levels. The … …American Journal of Applied Sciences, Vol. 12, Issue 1 · 26 Feb 2015 · 7,276 accessesView PDFCite
Research ArticleOpen accessIn the abstractCompressive and Shear Analysis of Rubber Block Under Large StrainK. Sridharan, R. SivaramakrishnanThe Elastomeric materials have found use in a wide range of applications, including hoses, tires, gaskets, seals, vibration isolators, bearings and dock fenders. The analysis of rubber blocks for its compression and shear behavior has been carried out using the imaging techniques. The dynamic stressing and its associated change in shape of the rubber blocks during large compression are very … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 18 Jun 2013 · 6,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Behavior of Tyre Tread BlockK. Sridharan, R. SivaramakrishnanThe Tyre tread pattern is the arrangement of blocks, grooves and voids, sipes and channels designed into the tread to enhance its grip on the road. Tread is the uppermost part of any tyre which contact into the road and it has its own performance towards mileage, traction, low noise and heat built up properties. It would be meaningful to … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 28 Jul 2012 · 9,791 accessesView PDFCite
Research ArticleOpen accessIn the abstractInter-Area Power Systems Stability Improvement by Static Synchronous Series CompensatorPrechanon KumkratugProblem statement: The inter-area power systems have special characteristic of the stability behavior. The improvement of inter-area power system is one of the important aspects in power system. Approach: This study applies the Static Synchronous Series Compensator (SSSC) to improve stability of inter-area systems. The SSSC is modeled and then is applied to be incorporated into the power system model … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 7,006 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatic and Dynamic Performance Improvement of Conventional Computer Numerical Control Machine Tool Bed with Hybrid Welded SteelS.S. Abuthakeer, P.V. Mohanram, G. MohankumarProblem statement: The advancements in machine tools to maximize the production by increasing spindle speeds have caused vibration in machine tools. The two functional requirements of machine tool bed for machine tools are high structural stiffness and high damping, which cannot be satisfied simultaneously if conventional metallic materials such as cast iron are employed. Hence there is a need to … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 11,479 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatic Segmentation of the Lips for Follow-UpM. L. Hamidatou, M. Guerti, S. Ait-AoudiaProblem statement: The objective of this study particularly aims the static segmentation of the lips. Approach: For that, we proposed algorithms for the determination of certain characteristic points of the lips, as well as a method of optimal slope allowing to trace the cubic ones forming external contours of the lips. Results: Finally to make sure of the performance of … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 6,755 accessesView PDFCite
Research ArticleOpen accessIn the abstractA GA Based Transmission Network Expansion Planning Considering Voltage Level, Network Losses and Number of Bundle LinesS. Jalilzadeh, H. Shayeghi, M. Mahdavi, H. HadadianTransmission Network Expansion Planning (TNEP) was studied considering voltage level, network losses and number of bundle lines using decimal codification based genetic algorithm (DCGA).
