Research ArticleOpen accessIn the abstractA Survey of Protein Fold Recognition AlgorithmsMohammed Said Abual-Rub, Rosni AbdullahProblem statement: Predicting the tertiary structure of proteins from their linear sequence is really a big challenge in biology. This challenge is related to the fact that the traditional computational methods are not powerful enough to search for the correct structure in the huge conformational space. This inadequate capability of the computational methods, however, is a major obstacle in facing … …Journal of Computer Science, Vol. 4, Issue 9 · 30 Sep 2008 · 6,877 accessesView PDFCite

Tahir, Moutaz Saleh et al.Problem Statement: With the free flow of routing data and the high availability of computer resources, possible threats to the networks can result in loss of privacy and in malicious use of information or resources that can eventually lead to large monetary losses. Approach: MD5 Authentication: Due to the major role that routing protocols play in computer network infrastructures, special … …Journal of Computer Science, Vol. 4, Issue 9 · 30 Sep 2008 · 7,204 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Enhancement for Security Mechanism in RoutersKhalid Khanfar, Riyad Khanfar, Walid Al-Ahmad, Eyas El-QawasmehProblem statement: Routers are very important components in any network. They control and organize the in-bound traffic and the out-bound traffic. Controlling a router by an intruder leaves the entire network unsecured. In different studies, Router security was discussed from different aspects such as the routing protocol, the firewall. In this research, we present a new effective security mechanism for … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 7,172 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Electric Power Distribution Using Hybrid Simulated Annealing ApproachWalid Ahmed, Alaa F. ShetaThe key goal of electric power distribution companies is to provide a high quality of service with a low cost of operation. The growing customer needs requires a re-distribution of the Power over various nodes of the Distributed Generation (DG) facilitates. The re-distribution might cause over load on various parts of the networks which if not correctly optimized might increase … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,606 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Digital Count-Down Display on Signalized Junction PerformanceM. R. Ibrahim, M. R. Karim, F. A. KidwaiIntersections are bottleneck in the highway networks and critical determinant of system’s capacity and safety. Recently, several countdown timers had been installed at intersections in Kuala Lumpur and some other cities in Malaysia. The function of these timers is to aid drivers to judge the amount of time left for them to get the green signal for moving (starting) their … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,761 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Study of Power Control Radio Resource Management Over WLANsZ. I. Dafalla, M. B.R. MurthyWireless Local Area Networks (WLANs) based on IEEE 802.11 standard have been rapidly growing. With limitations of the WLAN standard and rapid increase in wireless application demand, the air interface acts as bottleneck even in high-speed WLAN standards such as IEEE 802.11a and 802.11g with expected data transmission rates of up to 54 Mbps. To improve the overall performance of … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 7,255 accessesView PDFCite
Research ArticleOpen accessIn the abstractIrregular Class of Multistage Interconnection Network in Parallel ProcessingSandeep Sharma, K. S. Kahlon, P. K. Bansal, Kawaljeet SinghA major problem in designing a large-scale parallel and distributed system was the construction of an Interconnection Network (IN) to provide inter-processor communication. One of the biggest issues in the development of such a system was the development of an effective architecture and algorithms that have high reliability, give good performance (even in the presence of faults), low cost, low … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 7,057 accessesView PDFCite
Research ArticleOpen accessIn the abstractTesting Image Encryption by Output Feedback (OFB)Yas A. AlsultannyWhen it is necessary to securely transmit data in open networks, the encryption must be performed. Most of the cryptographic algorithms were mainly developed for text data. Unfortunately, algorithms those are good for textual data might not suitable for image.
