Research ArticleOpen accessIn the abstractThe Use of Swimmer Bars as Shear Reinforcement in Reinforced Concrete BeamMoayyad Al-Nasra, Naem Asha, Abdelqader Najmi, Taher Abu-LebdehThe behavior of reinforced concrete beams at failure by shear is distinctly different from their behavior by bending, which is considered to be unsafe mode of failure. The shear failure of beams is usually sudden without sufficient advanced warning and the diagonal cracks that develop due to excess shear forces are considerably wider than the flexural cracks. The cost and … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 15 Mar 2013 · 8,134 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Analysis of Large Capacity Endplate Steel ConnectionsMohamed Eldemerdash, Taher Abu-Lebdeh, Moayyad Al NasraProblem statement: Extended endplate connection is one of the most widely used beam-to column steel connections because of its fabrication simplicity, good overall performance and cost effectiveness compared with other connection types. The objective of this research is to develop three-dimensional finite element models to study the behavior of large capacity eight-bolt extended un-stiffened wide endplate steel connections, using current-technology … …Journal of Computer Science, Vol. 8, Issue 4 · 28 Jan 2012 · 6,912 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance of Thin-Film as Wavelength Filter in Wdm-Pof NetworkMohd Syuhaimi Ab. Rahman, L. S. Supian, Hadi Guna et al.Problem statement: Huge capacity for data transmission and bandwidth are becoming a need nowadays. High cost of implementation using optical fibers prevents utilization of the technology as wide as possible. Approach: Wavelength Division Multiplexing (WDM) was a technique that offers the solution for providing better bandwidth. WDM technique allows several signals that have different wavelengths to be transmitted in a … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 9 Dec 2011 · 7,270 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Network Design for Efficient Energy Utilization in Wireless Sensor NetworksChutima Prommak, Sujitra ModhirunProblem statement: This research presents a study of the optimal network design for efficient energy utilization in continuous data-gathering Wireless Sensor Networks (WSNs). We first examine the problem of minimizing the network cost through the minimum number of relay-station installation. Then we further investigate the problem of minimizing the energy consumption of the sensor nodes. Approach: We model the network … …Journal of Computer Science, Vol. 8, Issue 1 · 3 Nov 2011 · 7,350 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemediation Technologies for Marine Oil Spills: A Critical Review and Comparative AnalysisD. Dave, A.E. GhalyProblem statement: Anthropogenic activities pollute the oceans with oil through land run off, vessels accidents, periodic tanker discharges and bilge discharges. Oil spills are environmental disasters that impact human, plants and wild life including birds, fish and mammals. Approach: In this study, the International Guidelines for Preventing Oils Spills and Response to Disasters were reviewed and the characteristics of oil … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 2 Nov 2011 · 25,601 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Debarking and Insecticidal Treatments Using Cypermethrin on Fresh Logs of Indonesian Pine, Pinus merkusii, on Attack by Ambrosia Beetle, Xyleborus sp.Paimin Sukartana, Mohammad Muslich, Ginuk SumarniProblem statement: Indonesian pine logs (Pinus merkusii Yungh. et de Vr.) are vulnerable to attack by ambrosia beetle Xyleborus sp. Fresh cut logs kept for months in logging area are subject to heavily attack by the beetles. Approach: An experiment was conducted to evaluate effectiveness of debarking and insecticidal treatments using cypermethrin on fresh logs of the wood species on … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 27 Sep 2011 · 7,916 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Challenge for Routing Algorithms in Optical Multistage Interconnection NetworksMehrnaz Moudi, Mohamed OthmanProblem statement: A class of dynamic interconnection networks is Multistage Interconnection Networks (MINs) that connects input devices to output devices through a number of switch stages. MINs have assumed importance in recent years; because of their cost-effectiveness. Optical MINs are one type of MINs that have large transmission capacity in the communication networks. There is a major problem in Optical … …Journal of Computer Science, Vol. 7, Issue 11 · 29 Aug 2011 · 7,852 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Enhancement of Bayesian Inference Network for Ligand-Based Virtual Screening using Features SelectionAli Ahmed, Ammar Abdo, Naomie SalimProblem statement: Similarity based Virtual Screening (VS) deals with a large amount of data containing irrelevant and/or redundant fragments or features. Recent use of Bayesian network as an alternative for existing tools for similarity based VS has received noticeable attention of the researchers in the field of chemoinformatics. Approach: To this end, different models of Bayesian network have been developed. … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,721 accessesView PDFCite
