Research ArticleOpen accessIn the abstractLinear Protection Schemes Analysis in Scattered Placement Fiber-To-The Home-Passive Optical Network Using Customer Access Protection Unit SolutionMohammad Syuhaimi Ab-Rahman, Siti Asma Che Aziz, Kasmiran JumariProblem statement: This study highlights on restoration scheme proposed against failure in working line at the drop region for Fiber-To-The Home (FTTH) with a Passive Optical Network (PON). Whereas PON is a system that brings optical fiber cable and signals all or most of the way to the end user. Approach: Survivability scheme against failure is focused on scattered residence … …Journal of Computer Science, Vol. 8, Issue 1 · 26 Oct 2011 · 7,347 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Fly Negotiation for Urgent Service Level Agreement on Intercloud EnvironmentNawfal A. Mehdi, Ali Mamat, Hamidah Ibrahim, Shamala K. SubramaniamProblem statement: Impatient jobs are the jobs that have strict constraints in starting and completion time and need a fast response and attention in mapping to resources. The negotiation process in cloud computing needs a customer-provider agreement that leads to loss of a significant amount of time for impatient jobs. The huge increasing in cloud service providers makes selecting the … …Journal of Computer Science, Vol. 7, Issue 10 · 11 Aug 2011 · 7,948 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeart Rate Variability Analysis in Different Age and Pathological ConditionsM.E.S. Chelladurai, N. KumaravelProblem statement: Heart Rate Variability (HRV) has been used as a measure of mortality primarily with patients who had undergone cardiac surgery. The analysis of Heart Rate Variability (HRV) demands specific capabilities which are not provided either by parametric or nonparametric conventional estimation methods. The Empirical Mode Decomposition (EMD) adaptively estimates the Intrinsic Mode Functions (IMFs) of nonlinear nonstationary signals. … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 6,818 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign For Test Technique for Leakage Power Reduction in Nanoscale Static Random Access MemoryN. M. Sivamangai, GunavathiProblem statement: As technology scales down, the integration density of transistors increases and most of the power is dissipated as leakage. Leakage power reduction is achieved in Static Random Access Memory (SRAM) cells by increasing the source voltage (source biasing) of the SRAM array. Another promising issue in nanoscaled devices is the process parameter variations. Due to these variations, higher … …Journal of Computer Science, Vol. 7, Issue 8 · 15 Jul 2011 · 6,505 accessesView PDFCite
Research ArticleOpen accessIn the abstractShear Strength of Reinforced Concrete Beam Strengthened by Transverse External Post-tensionSayan Sirimontree, Boonsap Witchayangkoon, Nathavudh Khaosri, Jaruek TeerawongProblem statement: Shear failure of concrete beam is brittle manner without warning so inadequate design for shear of beam and/or material deterioration lead to the possibility of sudden failure of beam. The change of functional use and future increased load of structure lead to the need for strengthening of concrete structure. Approach: This research focuses on behaviors under static loading … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 31 Jan 2011 · 8,863 accessesView PDFCite
Research ArticleOpen accessIn the abstractRock Slopes Failure Susceptibility Analysis: From Remote Sensing Measurements to Geographic Information System Raster ModulesFilipello Andrea, Giuliani Andrea, Mandrone GiuseppeProblem statement: Two important step can be recognised in the rockfall analysis: the potential failure detection and the run out simulation. Analyzing the stability of rock slopes, most important kinematisms are planar or wedge slidings and topplings. The aim of this study was to coupling a deterministic approach for landslide initiation (potential rockfall source areas) with a runout analysis by … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,619 accessesView PDFCite
Research ArticleOpen accessIn the abstractCost Analysis of a Two Dissimilar-Unit Cold Standby Redundant System Subject to Inspection and Random Change in UnitsG. S. Mokaddis, C. H. MattaProblem statement: This study deled with the cost analysis of a two dissimilar unit cold standby redundant system subject to inspection and random change in units. In this system each unit works in two different modes normal and total failure. Assuming that the failure, repair, post repair, interchange of units and inspection times are stochastically independent random variables each having … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,298 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Oil Contamination on Geotechnical Properties of Basaltic Residual SoilZulfahmi Ali Rahman, Umar Hamzah, Mohd. Raihan Taha et al.Problem statement: Oil contamination due to accidental spillage or leakage brings hefty damage to the environments. It percolates steadily into subsurface environments and contaminates the soil and water system. Hydrocarbon contamination has not just affected the quality of the soil but will also alter the physical properties of oil-contaminated soil. Approach: This study presented the geotechnical properties of oil-contaminated soils … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 10,265 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Abnormal Modes of Hoisting DC Electric Drive SystemKosmas ZdrozisProblem statement: Host number of publications in which special attention was given to the behavior of the hoisting drives in abnormal modes was found. The effect of the failure of the main power supply on the electrical and mechanical parts of the hoisting drive when the motor is operating in the regenerative braking mode was not enough studied. Approach: In … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,241 accessesView PDFCite
Research ArticleOpen accessIn the abstractCompare Between Two-Unit Cold Standby and Warm Standby Outdoor Electric Power Systems in Changing WeatherG. S. Mokaddis, M. Salah EL-Sherbeny, Entesar Al-EsayehProblem statement: This study presents the reliability analysis of two mathematical models representing electric power systems operating in fluctuating outdoor weather (i.e., normal and stormy weather) and compared between two models. Approach: Model I deals the reliability analysis of a single-server two-unit cold standby, Model II deals the reliability analysis of a single-server two-unit warm standby, for two systems with … …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 7,439 accessesView PDFCite
