Research ArticleOpen accessIn the keywordsSimulations on Single Vacancy Defect Transients for Face-Center-Cubic StructureKwuanchanok Chansawang, Sunchai NilsuwankositThe simulations on single vacancy defect transients for FCC structure were conducted to study the change in its final structure, especially the average atomic volume. The numerical code &#34ALINE&#34 was employed for this purpose. The results obtained showed that when a single vacancy defect occurred in a perfect FCC-crystal structure, the average atomic volume was found to be suddenly increased … …Current Research in Biostatistics, Vol. 3, Issue 1 · 4 Sep 2013 · 6,675 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsModeling of an Industrial Riser in the Fluid Catalytic Cracking UnitMehran Heydari, Habib Ale Ebrahim, Bahram DabirProblem statement: The aim of this study is to obtain a model that can simulate the performance of an industrial fluid catalytic cracking unit in steady state. Approach: The reactions in the riser occur in a transported bed with the fluid and the solids in ideal plug flow. One of the main advantages of the model is that it does … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 8,117 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsStudy of Seven-Lump Kinetic Model in the Fluid Catalytic Cracking UnitMehran Heydari, Habib AleEbrahim, Bahram DabirProblem statement: The effective simulation of the Fluid Catalytic Cracking (FCC) operation requires a good understanding of many factors such as, reaction kinetic, fluid dynamics and feed and catalyst effects. Approach: In this model the reactor has been considered as an isothermal riser. The reactions in the riser occur with the fluid and the solids in ideal plug flow. Because … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,607 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsImproved Vertex Chain Code Based Mapping Algorithm for Curve Length EstimationHabibollah Haron, Amjad Rehman, L.A. Wulandhari, Tanzila SabaProblem statement: Image representation has always been an important and interesting topic in image processing and pattern recognition. However, curve tracing and its relative operations are the main bottleneck. Approach: This research presents the mapping algorithm that covers one of the vertex chain code cells, the rectangular-VCC cell. The mapping algorithm consists of a cell-representation algorithm that represents a thinned … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,841 accessesView PDF Cite

Review ArticleOpen accessIn the abstractA Review on Cognitive Radio for Next Generation Cellular Network and its ChallengesNandhakumar Pandi, Arun KumarCognitive Radio (CR) is considered an intelligent technology. It improves the utilization of the radio spectrum. The increasing number of new devices has resulted in growing congestion of the ISM bands. FCC issued an order only permitting unlicensed users (secondary users) to operate in white space without interfering with licensed users (primary users). Cognitive Radio Networks (CRNs) provides a solution … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 4 Apr 2017 · 8,986 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA New Approach in Individual Tree Counting of Nyatoh (Palaquium spp.) Using an Airborne SpectroradiometerKamaruzaman JusoffProblem statement: In Malaysia inadequate data are available to make decisions regarding the sustainable management of Nyatoh (Palaquium spp.). Factual data and estimation of Nyatoh in the lowland dipterocarp forest resources are still lacking or, if available, are not complete, reliable or up to date. The collection and compilation of information and updating of existing data in near real time … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,955 accessesView PDF Cite
