Research ArticleOpen accessAll words, across the recordPerformance Analysis of Global Search Algorithm Based Multiuser Detector for Multi Carrier Code Division Multiple Access System under Clipping NoiseS. Sivanesskumar, R. SukaneshProblem statement: Multi Carrier Code Division Multiple Access (MC-CDMA), a promising technology for the 4G communication systems. The major limitation of MC-CDMA system is the Multiple Access Interference (MAI) which is due to near-far effect, frequency offset and nonlinear power amplification due to clipping noise. Approach: The performance of MC-CDMA under clipping noise using Global search algorithm based Multiuser detector … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 6,687 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordComputer Simulator: An Educational Tool for Computer ArchitectureMihyar HessonThe great advancement in computer architecture and cache memory design and technology had a considerable influence on the way computer architecture was taught in universities. This requires students to be able to visualize the detailed activities that take place within a computer processor and its interaction with memory system. Computer simulators could effectively be used to enhance the understanding and … …American Journal of Applied Sciences, Vol. 3, Issue 11 · 30 Nov 2006 · 7,468 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordMorphing Mechanisms Part 1: Using Iterative Learning Control to Morph Cam Follower MotionNonglak Phetkong, Meng-Sang Chew, Richard W. LongmanThis study introduces the concept of morphing mechanisms. Mechanisms are normally designed for specific operating conditions and once they are built one may wish to use them under different operating conditions. In some cases, a mechanism may be imperfectly fabricated and one would like to get the intended ideal performance. In these cases, instead of designing, fabricating and replacing the … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,837 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordNumerical Simulation of the Transient Flow in Natural Gas Transmission Lines Using a Computational Fluid Dynamic MethodPedram Ghaseminejad, Nikan NoorbeheshtUntil now, almost all tools that are used to analyze gas transportation networks are based on steady flow conditions. Some design problems can be solved by the assumption of a steady state. However, some circumstances force us to use transient analyses, which commonly include changes in customer demand, the failure of a compressor station or gas pipeline ruptures. In this … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 6 Jan 2013 · 7,457 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSimulation of Phosphorus Movement in Unconfined Aquifer by Means of Visual MODFLOWSeyed Reza Saghravani, Sa'ari Mustapha, Shaharin Ibrahim et al.Problem statement: In three recent decays, computer software’s are used for assessing and predicting of what happened and what will happen for surface and subsurface water. These supplementary tools are calculating and presenting potential recharge of contamination to estimate and assess important issue in hydrogeology such as amount of contamination in drinking water. There is a source of contamination in … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 7,407 accessesView PDF Cite
