Research ArticleOpen accessIn the abstractA New Approach for Sub-Channels Assignment in Downlink Fourth Generation Mobile SystemsFakhreddine Khelifa, Abdelaziz SametProblem statement: We proposed a new heuristic method for subchannels allocation problem in the context. Approach: In this system, OFDM transmission method has been used, in order to reduce the effect of multipath fading, OFDMA to achieve multiple access schemes and flexibility in resource allocation. Results: An adaptive method for subchannels allocation is necessary in order to exploit the multiuser … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 6,593 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrating Components in Software Product Line to Build High Quality ProductsLena KhaledProblem statement: The main part of building any system is achieving high level of quality and developing qualities it is achieve. Many organizations do not take into account the highest level of quality as a main necessary part through building its systems; they think mainly on budget and reducing time to market. Approach: One of the important approached to achieved … …Journal of Computer Science, Vol. 7, Issue 8 · 14 Jul 2011 · 6,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance of MMSE Receiver based Multi Input Multi Output-Interleave Division Multiple-Access System with Multi-user Detection over Frequency Selective Wireless Communication ChannelKuttathatti Srinivasan Vishvaksenan, R. SeshasayananProblem statement: This study presents the performance analysis of turbo assisted Interleave Division Multiple-Access (IDMA) system with Multi Input Multi Output (MIMO) support for multi user scenario over correlated frequency selective and uncorrelated frequency selective channel. Approach: The key principle of IDMA is that interleaver unique which distinguishes the users in contrast to spreading sequence in Code Division Multiple Access … …Journal of Computer Science, Vol. 7, Issue 7 · 30 Jun 2011 · 6,837 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Ultra-Precision Polishing of Large Aperture Reaction Bonded Silicon Carbide MirrorYong Shu, Yifan Dai, Ziwen Zheng, Shengyi LiProblem statement: Silicon Carbide (SiC) optical materials have become the first choice for mirrors in space optical systems and large ground-based optical systems due to their outstanding mechanical, physical and optical properties. Compared with traditional optical glasses, SiC optical materials are provided with the characteristics of high hardness and multiphase, which embarrass the high efficient fabrication of SiC mirrors with … …Current Research in Nanotechnology, Vol. 1, Issue 2 · 21 Jun 2011 · 10,826 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpartan-3AN Field Programmable Gate Arrays Truncated Multipliers Delay StudyMohammed H. Al MijalliProblem statement: The image processing applications, such as MPEG video compression used in CT scan frames requires real time conditions and the algorithms should be verified and optimized before implementation which cannot be done with Application Specific Integrated Circuits (ASICs) because they are not reconfigurable and cost is very high. Approach: The FPGA is a viable technology that could be … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,431 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Secure Mobile Agent System against Tailgating AttacksP. Marikkannu, Adri Jovin, PurusothamanProblem statement: A lot of real time applications have extended their hands towards Mobile Agents to accomplish various tasks, due to its flexibility in its functionalities. Since Mobile Agent Systems are used in a distributed environment, it is obvious that they may be vulnerable to various security threats.
