Research ArticleOpen accessEvery word in the titleCost 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 · 6,881 accessesView PDFCite

The objectives of the study were to identify its potential application in Malaysia and to determine research areas that can be explored further to promote its application. Approach: Information required for the study was obtained … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 7,431 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Evolution Strategy for the Induction of Fuzzy Finite-state AutomataMozhiwen, WanminThis study presents an evolution strategy used to infer fuzzy finite-state automata from examples of a fuzzy language. We describe the fitness function of an generated automata with respect to a set of examples of a fuzzy language, the representation of the transition of the automata as well as the output of the states in the evolution strategy and the … …Journal of Mathematics and Statistics, Vol. 2, Issue 2 · 30 Jun 2006 · 6,699 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProduction of Cellulase from Oil Palm Biomass as Substrate by Solid State BioconversionMd. Z. Alam, Nurdina Muhammad, Mohd E. MahmatSolid state bioconversion (SSB) of lignocellulosic material oil palm biomass (OPB) generated from palm oil industries as waste was conducted by evaluating the enzyme production through filamentous fungus in lab-scale experiment. OPB in the form of empty fruit bunches (EFB) was used as the solid substrate and treated with the fungus Trichoderma harzianum to produce cellulase. The results presented in … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,445 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleStateless Aggregate Fair Marking Scheduler for Differentiated Service NetworksNandhini Sivasubramaniam, Palaniammal SenniappanIn diffserv networks, as the traffic flows vary constantly, it is very difficult to maintain the per-flow state. The computation of rate information of the traffic flow also becomes complex. In this study, we propose a Stateless Aggregate Fair Marking (SAMQ) with Multiple Queue Priority Scheduler for Differentiated Service (DiffServ) networks. Initially, priority scheduler is applied to the flows entering … …Journal of Computer Science, Vol. 9, Issue 1 · 9 Feb 2013 · 7,517 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Overview on Studying 222Rn Exhalation Rates using Passive Technique Solid-State Nuclear Track DetectorsMohamed Abd-ElzaherProblem statement: Uranium is a radiotoxic element found in trace quantities in alomost all natural accurring materials like soil, rock. Radon an inert radioactive gas whose predecessor in uranium, is emitted from soil beneath the house and from building materials. Accurate knowledge of exhalation rate plays an important role in characterization of the radon source strength in some building materials … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 17 Aug 2012 · 8,516 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIntrahydrogen Bonding and Transition States Between Enol and Enethiol Tautomers in β-ThioxoketonesBahjat A. Saeed, Rita S. Elias, Ebraheem Abdu MusadProblem statement: Hydrogen bonding is one of the most important concepts in chemistry because it is crucial to understand many different interactions both in gas phase and in condensed media. A particular subset is presented by the intramolecular hydrogen bonds where two ends of the same molecule interact, resulting in a ringlike structure. Approach: The study involved theoretical investigation of … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 18 Jul 2011 · 7,457 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCellulolytic Enzymes Production by Solid State Culture Using Pecan Nut Shell as Substrate and SupportMiguel A. Medina-Morales, José L. Martínez-Hernández, Heliodoro de la Garza, Cristóbal Noé AguilarProblem Statement: Great interest in the use of lignocellulosic biomass is increasing in order to diminish the accumulation of residues, such as pecan nut shells. One of the alternatives is the fungal degradation of these residues. Approach: The capacity of Trichoderma (coded as T1, T2 and T3) strains to produce cellulase and xylonite was evaluated. Results: Pecan nut shell fibers … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 8,027 accessesView PDFCite
