Research ArticleOpen accessIn the abstractA Heapify Based Parallel Sorting AlgorithmM. A.A.A. Hija, A. Zabian, S. Qawasmeh, O. H.A.A. HaijaQuick sort is a sorting algorithm whose worst case running time is θ(n2) on an input array of n numbers. It is the best practical for sorting because it has the advantage of sorting in place. Problem statement: Behavior of quick sort is complex, we proposed in-place 2m threads parallel heap sort algorithm which had advantage in sorting in place … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,766 accessesView PDFCite

Research ArticleOpen accessIn the abstractShort-Term and Medium-Term Load Forecasting for Jordan's Power SystemI. Badran, H. El-Zayyat, G. HalasaSeveral electric power companies are now forecasting electric loads based on conventional methods. However, since the relationship between loads and factors influencing these loads is nonlinear, it is difficult to identify its nonlinearity by using conventional methods. Most of papers deal with 24-h-ahead load forecasting or next day peak load forecasting. These methods forecast the demand power by using forecasted … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,081 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of Solar Radiation in High Energy Intensive of the World by PV SystemU. Ali RahomaSolar energy can be converted directly into electricity by means of solar cells. Solar cells currently cost around $3.50 per watt for crystalline cells and $2 per watt for thin-film wafers, which are less efficient but can be integrated into building materials. Industry analysts note that between 2000 and 2005, each doubling of cumulative production resulted in a price drop … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 9,680 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntisocial Psychopathy and HIV Risk among Alcohol and Other Drug (AOD) Abusing Adolescent OffendersRobert M. Malow, Jessy Dévieux, Rhonda Rosenberg et al.While the consensus is that HIV prevalence has remained low among adolescent offenders, the prevalence of STDs and HIV transmission risk behaviors is alarming, particularly for those abusing alcohol and other drugs and those displaying antisocial or conduct disorder characteristics. In the current study, 269 male and 110 female inner city, culturally diverse alcohol and other drug (AOD) abusing adolescent … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 6,811 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Token-Based Fair Algorithm for Group Mutual Exclusion in Distributed SystemsAbhishek Swaroop, Awadhesh Kumar SinghThe group mutual exclusion (GME) problem is a generalization of the mutual exclusion problem. In group mutual exclusion, a process requests a session before entering its critical section (CS). Processes requesting the same session are allowed to be in their CS simultaneously, however, processes requesting different sessions must execute their CS in mutually exclusive way. The paper presents a token-based … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 7,095 accessesView PDFCite

Md ArshadThis study presents methodology to generate sinusoidal pulse width modulation (SPWM) signal using Field Programmable Gate Array, FPGA technology. We discussed the unipolar switching scheme and the methodology to generate the signal with the predetermined switching frequencies. Simulation on the designed pulses was conducted using Altera Max Plus II simulation tools. This simulation method was used to get the desired … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,396 accessesView PDFCite
Research ArticleOpen accessIn the abstractProximity Aware Routing in Ad Hoc NetworksValerie Alandzi, Alejandro QuinteroMost of the existing routing protocols for ad hoc networks are designed to scale in networks of a few hundred nodes. They rely on state concerning all links of the network or links on the route between a source and a destination. This may result in poor scaling properties in larger mobile networks or when node mobility is high. Using … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,733 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Analysis of Plasticity- Induced Fatigue Crack Closure with Singular ElementR. Rahgozar, H. Saffari, R. TabatabaeiDeveloping a new method is presented to compute crack opening values in planar geometries using the crack surface nodal force distribution under minimum loading as determined from finite element analyses (FEM). In this technique, two-dimensional elastic-perfectly plastic finite element analyses of middle-crack tension (MT) geometry is conducted to study fatigue crack closure and to calculate the crack opening values under … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 6,850 accessesView PDFCite
