Research ArticleOpen accessEvery word in the titleCollaborative Caching Architecture for Continuous Query in Mobile DatabaseMohamed Ahmed Elfaki, Hamidah Ibrahim, Ali Mamat, Mohamed OthmanProblem statement: Cooperative caching, which allows sharing and coordination of cached data among clients, is a potential technique to improve the data access performance and availability in mobile ad hoc networks. However, variable data sizes, frequent data updates, limited client resources, insufficient wireless bandwidth and client’s mobility make cache management faces many challenges. Approach: In this study, we propose a … …American Journal of Economics and Business Administration, Vol. 3, Issue 1 · 7 Jan 2011 · 8,875 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleArtificial Neural Networks Based Modeling and Control of Continuous Stirred Tank ReactorR. Suja Mani Malar, T. ThyagarajanContinuous Stirred Tank Reactor (CSTR) is one of the common reactors in chemical plant. Problem statement: Developing a model incorporating the nonlinear dynamics of the system warrants lot of computation. An efficient control of the product concentration can be achieved only through accurate model. Approach: In this study, attempts were made to alleviate the above mentioned problem using &#34Artificial Intelligence&#34 … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,209 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleQuality Monitoring Using Principal Component Analysis and Fuzzy Logic Application in Continuous Casting ProcessSalah Bouhouche, Malek Lahreche, Abdelkrim Moussaoui, Jürgen BastThis paper deals with non linear system monitoring, based on a combined use of Principal Components Analysis (PCA) and fuzzy logic to process and quality monitoring. PCA coupled to fuzzy logic was used to estimate the fault or defect according to the dynamic changes in the process inputs-outputs characterized by T2 Hoteling and Squared Prediction Error (SPE). Correlation between the … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,238 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleConstrained Single Period Stochastic Uniform Inventory Model With Continuous Distributions of Demand and Varying Holding CostHala A. Fergany, M. E. El-SaadaniThis paper derives the single period stochastic inventory model with continuous distributions of demand and the holding unit cost is a function of the purchased (ordered) quantity. The objective is to find the optimal purchased quantity which minimizes the expected total cost for the period under a restriction on the expected varying holding cost when the demand during the period … …Journal of Mathematics and Statistics, Vol. 2, Issue 1 · 31 Mar 2006 · 7,156 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFeasibility of Continuous Flow Sequencing Batch Reactor in Domestic Wastewater TreatmentAmir Hossein Mahvi, A. R. Mesdaghinia, Farham KarakaniThe purpose of this study was to determine whether continuous flow SBR could provide efficient pollutant removal in domestic wastewater. The experiment was carried out using a pilot scale at Tehran University of Medical Sciences and in wastewater treatment plant. The results showed that 97.7% of BOD removal, 94.9% COD removal, 85.4% TKN removal, 71.4 % TN removal, 55.9% TP … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,765 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleKINETIC MODELLING OF CONTINUOUS-MIX ANAEROBIC REACTORS OPERATING UNDER DIURNALLY CYCLIC TEMPERATURE ENVIRONMENTE. A. Echiegu, A. E. GhalyA two-culture dynamic model which incorporated the effects of diurnally cyclic temperature was developed and used to predict the dynamic response of anaerobic reactors operated on dairy manure under two diurnally cyclic temperature ranges of 20-40°C and 15-25°C which represent the summer and winter in Nigeria. The digesters were operated at various hydraulic retention times and solid concentrations and some … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 2 · 29 Aug 2014 · 7,290 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Diurnally Cyclic Temperature on the Performance of a Continuous Mix Anaerobic DigesterAbdel E. Ghaly, Mariam T. Al HattabProblem statement: Concentrated livestock production is a major contributor to environmental problems through the production of large quantity of husks on relatively small land area. Anaerobic digestion represents a valuable means of cover by these husks into methane while reducing manure pollution problems. Methodology: An experimental apparatus, including data acquisition and control system, was developed and used to investigate the … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 4 · 19 Jan 2012 · 9,226 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStatistical Tool for Testing Agreement Level on Continuous DatasetsBasavarajaiah Mariyappa Doddagangavadi, B. Narasimha Murthy, Netra RajpurohitVarious analytical studies explored the new innovation for testing agreement level in medical and life sciences which can be simulated by Cohen ‘κ’ based on the practical applications. From the past medical literature, many authors suggested that, there is some disproportion research gaps that exists in the statistical methods for measuring the agreements between two or more observers from ‘Cohen … …Current Research in Biostatistics, Vol. 11, Issue 1 · 19 May 2021 · 11,780 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAccelerators in Macroeconomics: Comparison of Discrete and Continuous ApproachesVasily E. Tarasov, Valentina V. TarasovaWe prove that the standard discrete-time accelerator equation cannot be considered as an exact discrete analog of the continuous-time accelerator equation. This leads to fact that the standard discrete-time macroeconomic models cannot be considered as exact discretization of the corresponding continuous-time models. As a result, the equations of the continuous and standard discrete models have different solutions and can predict … …American Journal of Economics and Business Administration, Vol. 9, Issue 3 · 10 Nov 2017 · 8,633 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Manifestation of the Discrete and Continuous Types of Bioelectric Control of Natural Locomotion at the Over-Five AgeKazbek Chermit, Anatoliy Zabolotniy, Angelina ShakhanovaThe concept of physiology of activity by N.A. Bernstein, developed on the grounds of in-depth theoretical and empirical analysis of natural human locomotion, served as a basis for understanding the target determination of human behavior, the mechanisms of motor skills formation and levels of building movements. Scientific and technological progress has determined the emergence of new methods for registration of … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 27 May 2016 · 7,098 accessesView PDFCite
