Research ArticleOpen accessIn the abstractMultivariable Proportional Integral Controllers for Multi-Inputs-Multi-Outputs Desalination System Fed by a Photovoltaic GeneratorAbderrahmen Ben Chaabene, Anis SellamiProcess control is an essential part of the desalination industry that requires for driving at the optimum operating conditions an increase in the life time of the plant and reduction of the unit product cost. The desalination is a highly complex process, so that the majority of dynamic models are of the form of Multi-Inputs-Multi-Outputs (MIMO) systems. Problem statement: Driving … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,934 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergetic Performances Study of an Integrated Collector Storage Solar Water HeaterO. Helal, B. Chaouachi, S. Gabsi, C. BoudenProblem statement: Although that the interest attributed to the solar energy remains relatively limited, we attend today to the conception of several installations using the sun as energy source among which we quote the solar water heater. Approach: A study of energetic performances was taken on an integrated collector/storage solar water heater made in the National School of Engineers of … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 7,894 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Quality Improvement Using DVRC. Benachaiba, B. FerdiVoltage sags and swells in the medium and low voltage distribution grid are considered to be the most frequent type of power quality problems based on recent power quality studies. Their impact on sensitive loads is severe. The impact ranges from load disruptions to substantial economic losses up to millions of dollars. Different solutions have been developed to protect sensitive … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 8,040 accessesView PDFCite

A mineral ultrafiltration tubular membrane of CARBOSEP M2 … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,538 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Simulation of an Input Queuing Packet SwitchAzeddine Bilami, Mustapha Lalam, Mohamed BenmohammedMany Architectures of Internet routers, ATM and Ethernet switches have been proposed and analysed in literature. Theoretically reliable and valid solutions have been developed to achieve high performances, but a lot of them are not feasible in practice for commercial and technological reasons. Few papers develop the implementation and simulation aspects. The objective of this study is the design of … …Journal of Computer Science, Vol. 1, Issue 3 · 19 Sep 2005 · 6,926 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Impact of Business IT Strategic Alignment on Corporate PerformanceJohanes Fernandes Andry, Aziza Chakir, Ronald Maraden Parlindungan Silalahi et al.Information technology's role is vital for a company's progress in its business management. Companies must implement differentiation and cost-reduction strategies to gain a competitive advantage in intense competition, especially among electrical appliance distributors. The implementation of cost reduction cuts business processes by streamlining IT/IS. However, business processes still have not implemented information systems, such as stock data collection, transaction problem … …Journal of Computer Science, Vol. 19, Issue 3 · 28 Feb 2023 · 7,919 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAdvanced Grasshopper Optimization Scheduling Algorithm (AGOSA) for Multi-Cloud EnvironmentsS. Gowri, A. SumathiThe multi-cloud scheduling problem refers to the challenging task of efficiently allocating and managing resources across multiple cloud environments, involving the optimization of task scheduling, resource allocation to minimize makespan, reduce resource costs, and handle the complexity of multi-cloud environments while making optimal scheduling decisions. To overcome this issue. The paper proposes a novel scheduling algorithm, the Advanced Grasshopper Optimization … …Journal of Computer Science, Vol. 21, Issue 10 · 24 Nov 2025 · 2,646 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordInventory Management Systems with Hazardous Items of Two-Parameter Exponential DistributionAzizul Baten, Anton Abdulbasah KamilProblem statement: An exponentially decaying inventory was first developed by[10]. The certain commodities were observed to shrink with time by a proportion which can be approximated by a negative exponential function of time. Here, the novelty we took into consideration was that a constant hazardous rate followed by the two-parameter exponential distribution. Approach: We studied the inventory system with two-parameter … …Journal of Social Sciences, Vol. 5, Issue 3 · 30 Sep 2009 · 8,297 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCost Analysis of Two-Dissimilar-Unit Cold Standby System with three States and Preventive Maintenance Using Linear First Order Differential EquationsM. Y. HaggagProblem statement: Several researchers have studied the reliability behavior of a three state systems, but no attention was paid to the reliability evaluation due to preventive maintenance. The better maintenance of the system originates better reliability. Also, standby support increases the reliability of the system. Approach: Determine the efficacy of preventive maintenance on the reliability and performance of the system. … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 6,873 accessesView PDFCite
