Research ArticleOpen accessIn the abstractHeterogeneous Modeling, Identification and Simulation of Activated Sludge ProcessesIbrahim H. Mustafa, G. Ibrahim, Ali Elkamel, A. H. ElahwanyProblem statement: The activated sludge system is a complex dynamic process and must account for a large number of reactions between large numbers of components. There is necessity for simulation models which describe the dynamic behavior of the activated sludge process. The application of the models in most treatment plants is limited due to lack of appropriate data acquisition and … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,595 accessesView PDFCite
Research ArticleOpen accessIn the abstractValidation of the Calculation and Measurement Techniques of Earth Resistance ValuesN. Mohamad Nor, R. Rajab, K. RamarMuch research has been published in the literature on the mathematical approaches to obtain the most accurate earth resistance and resistivity values. However, the published research only conducted the comparisons among the mathematical/computational techniques and so far none has conducted validation tests of these mathematical/computational methods against the real earth resistance measurement at real field sites. Thus, the main contribution … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,220 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Response Time of Authorization Process of Credit Card System Using Multi-Threading and Shared-Memory Pool TechniquesSiti H.A. Hamid, Mohd H.N.M. Nasir, Wong Y. Ming, Hazrina HassanCurrent credit card authorization was developed on single-threaded model whereby authentication process takes longer time to respond due to sequential process of card's risk management profile and its limitation of handling huge number of simultaneous transactions at single point of time. As a result, the performance of the authorization system was affected during peak hours. This study presented an architectural … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,238 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of an Automatic Blast Furnace through Integrated Simulation ModelingAli Azadeh, S. F. GhaderiThe objective of this study was to develop an integrated simulation model of an automatic blast furnace in a full-scale steelmaking factory. The integrated simulation model introduces a set of optimizing alternatives through sensitivity analysis. The simulation model is built by considering all major and detailed operations and interacting systems of the blast furnace workshop. The workshop is composed two … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 7,099 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Solar Radiation SystemM.S. Alam, Sushanta Kumar Saha, M.A.K. Chowdhury et al.In this research work, a mathematical model for simulation of the solar radiation system has been developed by using a system dynamics methodology. Bangladesh is used here for model validation. The simulated results obtained from this model have compared with the experimental results and found reasonably a good agreement. Therefore the performance of the model is to be expected as … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Systematic Literature Review for Implementing Data Ops in the Data Warehouse Lifecycle during the ETL PhaseAhmed Bahaa, Sherif Ragab Eldemerdash, Hanan FahmyNowadays, no one can deny the importance of Data Ware House (DWH) in all organizations. The most important components in Data Ware House (DWH) are the Extraction, Transformation, Loading (ETL) phase. Data cleaning is a basic piece of the transformation stage in Data Warehousing. This may affect critical activities such as data collection and decision-making in various organizations Data Ops … …Journal of Computer Science, Vol. 17, Issue 11 · 10 Nov 2021 · 7,554 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Alternative Cropping and Nutrient Management Systems with Soil and Water Assessment Tool for the Raccoon River Watershed Master PlanPhilip Gassman, Manoj Jha, Calvin Wolter, Keith SchillingThe Soil and Water Assessment Tool (SWAT) ecohydrological model was used to assess a suite of adaptive nutrient management, alternative cropping system and combination scenarios in support of a Master Plan that was developed to help guide policy makers, land owners and other stakeholders in improving water quality for the 9,400 km2 Raccoon River watershed in west central Iowa, located … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 9 Sep 2015 · 7,619 accessesView PDFCite
Research ArticleOpen accessIn the abstractEMPIRICAL COMPARISON OF TWO METRICS SUITES FOR MAINTAINABILITY PREDICTION IN PACKAGES OF OBJECT-ORIENTED SYSTEMS: A CASE STUDY OF OPEN SOURCE SOFTWAREK.G. MadhwarajSoftware maintainability has been an important external quality attribute that concerns both styles of software development, the proprietary model as well as open source. As lots of open source software are predominantly built using the OO paradigm, there exists a need for empirical validation with respect to certain quality aspects especially maintainability. There are a few studies in the past … …Journal of Computer Science, Vol. 10, Issue 11 · 10 Dec 2014 · 8,218 accessesView PDFCite
Research ArticleOpen accessIn the abstractHOMOLOGY MODELING AND MOLECULAR DYNAMICS STUDIES OF EC1 DOMAIN OF VE-CADHERIN TO ELUCIDATE DOCKING INTERACTION WITH CADHERIN-DERIVED PEPTIDEVivitri Dewi Prasasty, Usman Sumo Friend Tambunan, Teruna Jaya SiahaanVE-cadherin is a protein in the cadherin family that is found at the adherens junctions of the microvessel endothelial cells of the Blood-Brain Barrier (BBB). It is recognized as the homotypic cell adhesion molecules and there is limited structural information on how VE-cadherins mediate cell-cell adhesion. It has been shown that the EC1 domain of cadherins is important for the … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 25 Jun 2014 · 7,534 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Emissions from Power Stations on the Ambient Air Quality of Selected Urban Areas in KuwaitBader N. Al-Azmi, V. Nassehi, A.R. KhanIn Kuwait, two main power stations, one comprising of seven-300MW steam generators at Doha and other with eight-300MW steam generators at Subyia cover the major power requirement of Kuwait city. These stations used different types of fuel oil as the prime source of energy that has different sulpher contents (S%). Comprehensive emission inventories for year the 2001 were used to … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,016 accessesView PDFCite
