Research ArticleOpen accessIn the abstractEffective Coagulation Technology for Treatment of Grease Filter WashwaterAbdel E. Ghaly, A. Snow, B.E. FaberThe treatment of grease filter washwater by chemical coagulation and sedimentation using different dosages of aluminum sulfate was investigated. Pollutant removal efficiency was measured in terms of total solids, pH and optical density. The process was found to be effective at the room temperature and the filter washwater pH (9.5). The optimum aluminum sulfate dosage was 2 g/L. The treatment … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 6,819 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuzzy Logic Controller Based Three-phase Shunt Active Filter for Line Harmonics ReductionC. Sharmeela, M. R. Mohan, G. Uma, J. BaskaranHarmonic distortion is a form of electrical noise. It is a superposition of signals, which are of multiples of fundamental frequency. Proliferation of large power electronic systems results in increased harmonic distortion. Harmonic distortion results in reduction of power quality and system stability. This paper presents fuzzy control applicable for active power filter for three-phase systems, which are comprised of … …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 7,111 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe 2D Eulerian Approach of Entrained Flow and Temperature in a Biomass Stratified Downdraft GasifierA. Rogel, Jasni AguillónThis paper describes a “1-D+2-D” numerical model used to simulate the gasification of pine wood pellets in a stratified downdraft gasifier whereby Eulerian conservation equations are solved for particle and gas phase components, velocities and specific enthalpies. The model takes into account the biomass particle process such as heating up, drying, primary pyrolysis of biomass, secondary pyrolysis of tar, homogeneous … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 7,257 accessesView PDFCite
Research ArticleOpen accessIn the abstractReliability Evaluation of Distributed Computer Systems Subject to Imperfect Coverage and Dependent Common-Cause FailuresLiudong Xing, Akhilesh ShresthaImperfect coverage (IPC) occurs when a malicious component failure causes extensive damage due to inadequate fault detection, fault location or fault recovery. Common-cause failures (CCF) are multiple dependent component failures within a system due to a shared root cause. Both imperfect coverage and common-cause failures can exist in distributed computer systems and can contribute significantly to the overall system unreliability. … …Journal of Computer Science, Vol. 2, Issue 6 · 28 Sep 2006 · 6,840 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacteristics of Effective Dynamics and its Use in Developing the Product Quality and Proceeds in Inclusively FirmNasir Al KloubControlling product size type and quality is a set of technical, technological, organizational and preparatory procedures correlated in one process. Indexes for the demand for product in foreign and local markets vary according to its quality, and consequently technological processes should guarantee and warrant protects of subtle qualities and quality indexes. Securing quality of the product in all industrial sectors … …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Aug 2006 · 6,248 accessesView PDFCite
Research ArticleOpen accessIn the abstractLoad Balancing on Open Networks: A Mobile Agent ApproachR. B. Patel, Neetu AggarwalIn order to disperse the load on a Web server, generally the server cluster is configured to distribute access requests, or mirror servers are distributed geographically on different networks. Use of the Internet and the World-Wide-Web (WWW) has become widespread in recent years and mobile agent technology has proliferated at an equally rapid rate to evenly distribute the requests to … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 6,620 accessesView PDFCite
