Research ArticleOpen accessIn the abstractFinite Element Analysis of Composite Hardened Walls Subjected to Blast LoadsGirum S. UrgessaProblem statement: There is currently no standard design guideline to determine the number of composites needed to retrofit masonry walls in order to withstand a given explosion. Past design approaches were mainly based on simplified single-degree-of-freedom analysis. A finite element analysis was conducted for concrete masonry walls hardened with composites and subjected to short duration blast loads. Approach: The analysis … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,266 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Policy-Based Admission Control Scheme for Voice over IP NetworksSami Alwakeel, Agung PrasetijoProblem statement: In Voice Over IP (VOIP) network, when more calls are admitted to the network, more voice packet traffic is created. Since bandwidth is always limited, this may result network congestion and/or may affect voice quality. Thus, we needed a mechanism for improving the Quality of Service (QoS) by controlling VOIP calls admission. Approach: Given a specified bandwidth and … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 6,609 accessesView PDFCite

Research ArticleOpen accessIn the abstractElectroosmotic Phenomena in Organic SoilsAfshin Asadi, Bujang B.K. Huat, M. M. Hassim et al.Organic soils or peat represent an accumulation of disintegrated plant remains which have been preserved under condition of incomplete aeration and high water content. In order to develop a fundamental understanding of electroosmotic phenomena in peat, initially microelectrophoresis studies were carried out to conceptualize the electrokinetic phenomena. Then electroosmosis experiments were conducted on rigid cube samples containing 0.0001 M NaCl-water … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,101 accessesView PDFCite
Research ArticleOpen accessIn the abstractHuman Computer Interaction Approach in Developing Customer Relationship ManagementMohd H.N.M. Nasir, Mustaffa Kamal, Wan A.W. RozaliProblem statement: Many published studies have found that more than 50% of Customer Relationship Management (CRM) system implementations have failed due to the failure of system usability and does not fulfilled user expectation. This study presented the issues that contributed to the failures of CRM system and proposed a prototype of CRM system developed using Human Computer Interaction approaches in … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 7,140 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. The OFB mode of encryption implemented to test five images of different resources, by using three combinations (schemes): a combination … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,193 accessesView PDFCite

MalowProblem statement: Delinquent adolescents with substance abuse disorders frequently engage in behaviors that elevate their risk of contracting HIV. Although effective risk reduction interventions are urgently needed, there is uncertainty about the nature of interventions required to produce change. Approach: This study evaluated whether Modified version of Becoming A Responsible Teen (M-BART) produced greater reductions in drug use and sexual … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 6,339 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrating Software Architecture Concepts into the MDA Platform with UML ProfileAdel Alti, Tahar Khammaci, Adel SmedaArchitecture Description Languages (ADLs) provide an abstract representation of software systems. Achieving a concrete mapping of such representation into the implementation is one of the principal aspects of MDA (Model Driven Architecture). Integration of ADLs within MDA confers to the MDA platform a higher level of abstraction and a degree of reuse of ADLs. Indeed they have significantly different platform … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,602 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation of Magnetic Paper from Kenaf: Lumen Loading and in situ Synthesis MethodC. H. Chia, S. Zakaria, S. Ahamd et al.Magnetic papers have been successfully prepared from unbleached kenaf (hibiscus cannabinus) kraft pulps via the lumen loading and in situ synthesis process. The lumen loading method allows the magnetic fillers to be introduced into the lumen of fibres and at the same time leaving the external surfaces free from filler, resulting the better inter-fibre bonding and subsequently its papermaking properties … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,514 accessesView PDFCite
