Research ArticleOpen accessIn the abstractMeasuring the Resiliency of the Manhattan Points of Entry in the Face of Severe DisruptionMayada Omer, Ali Mostashari, Roshanak NilchianiProblem statement: Resilient infrastructure systems are able to continue to provide the expected service levels following disruptive events. Implementing resiliency in infrastructure systems requires knowledge of the current resiliency of the system and a methodology by which different resiliency strategies can be evaluated. In the transportation infrastructure in particular, disruptions cause delays, which will in turn incur substantial economic losses … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 15 Mar 2011 · 9,671 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Quantum and Classical Key Scheme for Two Servers Password AuthenticationA. Krishnan, T.S. ThangavelProblem statement: Traditional user authentication system uses passwords for their secured accessibility in a central server, which is prone to attack by adversaries. The adversaries gain access to the contents of the user in attack prone servers. To overcome this problem, the multi-server systems were being proposed in which the user communicate in parallel with several or all of the … …Journal of Computer Science, Vol. 6, Issue 12 · 2 Nov 2010 · 6,644 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving the Performance of Backpropagation Neural Network Algorithm for Image Compression/Decompression SystemOmaima N.A. AL-AllafProblem statement: The problem inherent to any digital image is the large amount of bandwidth required for transmission or storage. This has driven the research area of image compression to develop algorithms that compress images to lower data rates with better quality. Artificial neural networks are becoming attractive in image processing where high computational performance and parallel architectures are required. … …Journal of Computer Science, Vol. 6, Issue 11 · 26 Oct 2010 · 8,370 accessesView PDFCite
Research ArticleOpen accessIn the abstractParallel Calculation Sensitivity Function for Multi Tasking EnvironmentsHamed Al Rjoub, Ahmed Al-Sha'orProblem statement: Calculating sensitive functions for a large dimension control system to find the unknowns vectors for a linear system in both single and multi processors, is not considered internally compatible with multi tasking environments, so breaking the process can cost time and memory and it couldn't be paused, resumed and saved as patterns for later continuity. This study is … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Aug 2010 · 6,445 accessesView PDFCite

Research ArticleOpen accessIn the abstractA Novel Methodology for Designing Radix-2n Serial-Serial MultipliersAbdurazzag Sulaiman AlmiladiProblem statement: The fast growth and increase in complexity of digital and image processing systems necessitate the migration from ad hoc design methods to methodological ones. Methodologies will certainly ease the trade off selection for those systems and shortens the design time. To increase those gained values and expand the searching space more appropriate methodologies need to be developed. Approach: … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcoustic Echo Cancellation: Dual Architecture ImplementationB. Stark, B. D. BarkanaProblem statement: With the rise in mobile communication, it is becoming more frequent to use a communication device in an enclosed noisy environment, such as a subway or in a lobby. In this setting however, the received microphone is severely degraded by the echo from the speaker and background noise. The audio processing necessary to clarify the desired speech can … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,382 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Test Time for System-on-Chip Designs using Fuzzy Logic and Process AlgebraG. Rohini, S. SalivahananProblem statement: Test scheduling is crucially important for optimal SoC test automation to allocate the limited available test resources. In this study we introduced a fuzzy based engine to allocate test resources. The minimized test application time can be achieved by test pipelining. However the test power consumption incurred during test procedure must be controlled in order not to offend … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 7,520 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improved Lazy Release Consistency ModelChapram Sudhakar, T. RameshProblem statement: A network of workstations, viewed as a distributed shared memory system can be used to develop and test parallel algorithms. Approach: For implementing parallel algorithms on such DSMs shared memory consistency model plays a vital role. Results: However on a LAN, strict consistency models like Sequential Consistency model (SC) are not useful since the communication is slow. In … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 7,144 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulti Microkernel Operating Systems for Multi-Core ProcessorsRami MatarnehProblem statement: In the midst of the huge development in processors industry as a response to the increasing demand for high-speed processors manufacturers were able to achieve the goal of producing the required processors, but this industry disappointed hopes, because it faced problems not amenable to solution, such as complexity, hard management and large consumption of energy.
