Research ArticleOpen accessIn the abstract3D Numerical Study on Laminar Forced Convection in V-Baffled Square ChannelAmnart Boonloi, Withada JedsadaratanachaiThe article presents a mathematical study of fully developed periodic laminar flow visualization and heat transfer characteristics in an isothermal wall square-channel fitted with V-shaped baffles on one wall. The computations based on the finite volume method together with the SIMPLE algorithm have been performed. The investigation covers a range of Re based on the hydraulic diameter of the channel, … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 6,314 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Explanatory Variables of Outward Foreign Direct Investment: Panel EvidenceNicholas Apergis, Dimitrios Asteriou, Kalliroi PapathomaAlong with the traditional macroeconomic determinants of FDI, additional explanatory variables, such as the exchange rates, should be encountered in undertaking physical investment decisions, as these variables affect several comparative costs and the cost of lending. The goal of this study is to examine for the first time panel data evidence of Greek outward FDI flows directed to 16 EU … …American Journal of Economics and Business Administration, Vol. 4, Issue 4 · 6 Jul 2013 · 7,074 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStateless Aggregate Fair Marking Scheduler for Differentiated Service NetworksNandhini Sivasubramaniam, Palaniammal SenniappanIn diffserv networks, as the traffic flows vary constantly, it is very difficult to maintain the per-flow state. The computation of rate information of the traffic flow also becomes complex. In this study, we propose a Stateless Aggregate Fair Marking (SAMQ) with Multiple Queue Priority Scheduler for Differentiated Service (DiffServ) networks. Initially, priority scheduler is applied to the flows entering … …Journal of Computer Science, Vol. 9, Issue 1 · 9 Feb 2013 · 7,517 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRectangular Storm Sewer Design Under Equal Sediment MobilityJaber AlmedeijRectangular storm sewers are conduits delivering water to outfall locations and have sizes that are typically larger than standard pipes, by which they become subject to more sediment deposits during operation and thus require higher flow strengths to maintain the bed clean. This study suggests a design procedure of self-cleansing rectangular sewers based on maintaining a lower limit of Shields … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 19 Jun 2012 · 7,758 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGroundwater Flow Systems and Their Response to Climate Change: A Need for a Water-System View ApproachJoel J. Carrillo-Rivera, Antonio CardonaProblem statement: The interest in early hydrogeological studies was the aquifer unit, as it is the physical media that stores and permits groundwater transfers from the recharge zone to the discharge zone, making groundwater available to boreholes for water extraction. Approach: Recently, the aquifer concept has been complemented by the groundwater flow system theory, where groundwater may be defined by … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 7 Apr 2012 · 8,085 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPurpose-based Versus Flow-Based Access Control for PrivacySabah Al-Fedaghi, Bashayer Al-Babtain, Maha Al-FahadProblem statement: Data protection legislation requires handling of Personal Identifiable Information (PII) in special ways to guarantee privacy. Specifically, the notion of handling purpose plays an important role in current access control mechanisms that allow only actions corresponding to intended purposes. A problem that arises in this context is how to ensure that PII is used solely for the intended … …Journal of Computer Science, Vol. 8, Issue 4 · 8 Feb 2012 · 6,821 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMultipath Adaptive Packet Dispersion for Voice ApplicationsJ. Faritha Banu, V. RamachandranProblem statement: The quality of Voice over IP applications is decided by the main factors like network capacity and technologies such as codec type, Packet Loss Concealment (PLC) and Forward Error Correction (FEC). Approach: In MPLS networks multiple Label Switched Paths (LSP) are established between MPLS ingress and egress nodes to enhance the network performance and QoS for subscribers. To … …Journal of Computer Science, Vol. 8, Issue 4 · 27 Jan 2012 · 7,720 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFramework for Managing the Very Large Scale Integration Design ProcessSabah Al-Fedaghi, Eman Al-DwaisanProblem statement: The VLSI design cycle was described in terms of successive states and substages; it starts with system specification and ends with packaging. At the next descriptive level, currently known methodologies (e.g., flowchart based, object-oriented based) lack a global conceptual representation suitable for managing the VLSI design process. Technical details were intermixed with tool-dependent and implementation issues such as … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 13 Dec 2011 · 7,497 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCongestion Control in Wireless Ad Hoc Networks by Enhancement of Transmission Control ProtocolN. Premalatha, A. M. NatarajanProblem statement: Transmission Control Protocol is the Internet’s most widely used transport control protocol. TCP’s strength lies in the adaptive nature of its congestion avoidance and control algorithm and its retransmission mechanism. In TCP Vegas rerouting (a path), which change the propagation delay of the connection and this may be able to result in a substantial decrease in through put. … …Journal of Computer Science, Vol. 7, Issue 12 · 17 Oct 2011 · 6,690 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Effective Contention Aware Stable Path Finding Approach to Provide Quality of Service in Mobile Ad hoc NetworksD. S. Thenmozhi, M. RajaramProblem statement: The application of Mobile Ad hoc NETworks (MANETs) has been increasing every day. Most applications that attract interest for use in current wired networks (e.g. video conferencing, on line movies and camera enabled instant messenger) would attract interest for MANETs also. Many applications that use MANETs include multimedia data that require Quality of Service (QoS) support for effective … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 6,745 accessesView PDF Cite
