Research ArticleOpen accessIn the keywordsDetermining Road Lighting Impact on Traffic Stream CharacteristicsBen-Edigbe Johnnie, Kurnia Yuli AstridThe study is aimed at estimating road lighting impact on traffic stream characteristics; flow, speed, density and headway for an uninterrupted traffic flow. Volume, speed and headway data were collected during daylight, road lighting and dry weather conditions. Flowrate, speed, density and headways were estimated for daylight and road lighting periods; then compared. Since flowrate, free-flow speed, optimum speed critical … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 2 Jul 2013 · 7,020 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPrevention of Spoofing Attacks in the Infrastructure Wireless NetworksWesam S. Bhaya, Samraa A. AlAsadyProblem statement: Spoofing Attack is one of the vulnerabilities in the wireless networks, which is a situation in which the intruder successfully masquerades as legal one. Spoofing Attacks will decrease the performance of the network and violate many security issues. In the networks that use MAC address based filtering approach to authenticate the clients, the spoofer just needs to get … …Journal of Computer Science, Vol. 8, Issue 10 · 4 Sep 2012 · 7,838 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUnmet Needs in Chronic Obstructive Pulmonary Disease: A Metasynthesis ProtocolRebecca T. Disler, Anna Green, Tim Luckett et al.Problem statement: Chronic obstructive pulmonary disease is a chronic progressive illness. Despite the high burden experienced by individuals in the advanced stages of illness, individuals with advanced COPD continue to have unmet needs and limited access to palliative care. This Metasynthesis seeks to describe: the barriers and facilitators care access and provision; the unmet needs of individuals with advanced COPD, … …International Journal of Research in Nursing, Vol. 3, Issue 1 · 19 Jun 2012 · 7,579 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLifestyles and Migraine AttackHui Jun Chih, Wenbin LiangProblem statement: Migraine is a headache disorder of serious public health concerns as many sufferers are permanently disabled and incapable of carrying out simple daily routines. Migraine is contributed by biological and lifestyle factors. Understanding the association between these factors and migraine, particularly the modifiable lifestyle factors, can reduce the prevalence of this chronic disease and ease the burden on … …Current Research in Medicine, Vol. 2, Issue 2 · 2 Dec 2011 · 7,517 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDistributed Cluster Based Routing Technique with Multiple Sinks for Wireless Sensor NetworksS. V. Manisekaran, R. VenkatesanProblem Statement: In order to reduce or minimize energy consumption and to improve bandwidth utilization in Wireless Sensor Networks (WSN), it was essential to consider its architecture in the network topology, power consumption, data rate and fault tolerance. Our objective is to formulate an effective cluster formation of nodes with multiple sinks to reduce power consumption and minimize the data … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 28 Jun 2012 · 6,865 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Improved Location aided Cluster Based Routing Protocol with Intrusion Detection System in Mobile Ad Hoc NetworksS. Mangai, A. TamilarasiProblem statement: Routing and security are the main challenges for ad hoc networks due to dynamic topology as well as resource constraints. A designed protocol must provide scalable routing with better security. Lack of any central coordination and shared wireless medium makes them more vulnerable to attacks than wired networks. And also resource constraints such as limited energy and size … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 7,103 accessesView PDFCite

Research ArticleOpen accessIn the keywordsBy-pass Devices as Effective Means of Protection from the Hydraulic HammerKhalid S. Al-RababaSwitching-off the parallel working pump units causes sudden discharge changes in parallel pipe lines, as a result of that hydraulic shocks takes place. The damping of these shocks can be achieved by the installation of the by-pass devices between the parallel lines of the piping system. The analytical calculations demonstrate that the reduction in hydraulic shocks reaches 40% and considerable … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,912 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Operational Features of Pumping Stations Equiped with Parallel-Connected Centrifugal Pumps for Land-ReclamationKhalid S. Al-RababaThe required water supply of a pump could be provided by means of different combinations of pressure piping and pumping units at different operational costs. The basic indices describing the operational modes for the individual and group pumping units, including the values of the efficiency, are computed. The adequacy of the calculational results that based on the developed mathematical models … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,802 accessesView PDFCite
