Research ArticleOpen accessAll words, across the recordAn Independent Rough Set Approach Hybrid with Artificial Bee Colony Algorithm for Dimensionality ReductionNambiraj Suguna, Keppana Gowder ThanushkodiProblem statement: Dimensionality reduction is viewed as an important pre-processing step for pattern recognition and data mining. As the classical rough set model considers the entire attribute set as a whole to find the subset, comparing all possible combinations of sets of attributes is difficult. Approach: In this study, we have introduced an improved Rough Set-based Attribute Reduction (RSAR) namely … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 8,342 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOptimization of the Geometrical Parameters of a Solar Bubble Pump for Absorption-Diffusion Cooling SystemsN. Dammak, B. Chaouachi, S. Gabsi, M. BourouisProblem statement: The objective of this study was to optimize the geometrical parameters of a bubble pump integrated in a solar flat plate collector. Approach: This solar bubble pump was part of an ammonia/water/helium (NH3/H2O/He) absorption-diffusion cooling system. Results: An empirical model was developed on the basis of momentum, mass, material equations and energy balances. The mathematical model was solved … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 8,378 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordModeling and Optimization of the Vortex Tube with Computational Fluid Dynamic AnalysisK.K. Zin, A. Hansske, F. ZieglerProblem statement: This study illustrated the influence of the Length to Diameter (L/D) on the fluid flow characteristics inside the counter-flow Ranque-Hilsch vortex tube predicted by Computational Fluid Dynamic (CFD) and validated through experiment. Approach: The swirl velocity, axial velocity, radial velocity component and also secondary circulation flow (back-flow) along with the pressure within the vortex tube were simulated and … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,833 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOptimization of Field Development Scheduling, East Unity Oil Field, SudanTagwa A. Musa, Ahmed A.E. Ibrahin, Guan ZhenLiang, Fei QiIn order to improve the reservoir performance in East Unity oil field Sudan, the studies focused on characterization, modeling and simulation of the actual performance and future development. A model was constructed using a three-phase, three dimensional, black oil simulator (ECLIPSE). In this study a data from East Unity oil field Sudan started production at July 1999 was used to … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,166 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA New Approach to Model Concentrating PV Cells Under Non-Uniform IlluminationHang Zhou, Yuehong Su, Gang Pei et al.Concentrating PV (CPV) cells are often designed optimally depending on solar concentrator characteristics and operating conditions to ensure the best system performance. Before reaching a PV cell, solar radiation may experience some optical losses caused by the different physical phenomena occurring in a solar concentrator. A particular issue with the CPV technology is the non-uniformity of the concentrated radiation, which … …Energy Research Journal, Vol. 8, Issue 2 · 30 Aug 2017 · 7,144 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordInventory Models with Power Demand and Inventory-Induced Demand with Holding Cost FunctionsRakesh Prakash Tripathi, Sarla Pareek, Manjit KaurIn real life customers are motivated to buy more if there is more availability of product. In this study, we develop inventory model for inventory dependent demand with different holding cost function. Mathematical formulations are discussed for two situations i.e., power demand rate with inventory dependent holding cost functions and inventory-induced demand rate with time and inventory dependent holding cost … …American Journal of Applied Sciences, Vol. 14, Issue 6 · 6 Apr 2017 · 7,544 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNew Strategy to Optimize Lean Supply Chain Design by Meta-HeuristicThi Hong Dang Nguyen, Thien My DaoThis paper aims at presenting one novel quantitative strategy of optimizing the design of Lean supply chain using Meta-Heuristics. While classifying Lean Manufacturing tools in two categories, namely Functional and Tier Lean tools, we propose a new framework to design the Lean supply chain by implementing the former into a 5-echelon Fat supply chain. As the following step, we investigate … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 9 Mar 2017 · 7,953 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOptimization of Biodiesel Production from Spent Palm Cooking Oil Using Fractional Factorial Design Combined with the Response Surface MethodologyS.M. Zakir Hossain, Nahid Sultana, Muhammad Faisal Irfan et al.Fractional Factorial Design (FFD) of the experiments combined with the response surface methodology was used to determine the optimum conditions for the production of biodiesel from Used Cooking Oil (UCO) in a batch reactor. Spent palm olein cooking oil was used as a raw material for biodiesel production as it is commonly used in most of the restaurants in Bahrain. … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 22 Nov 2016 · 8,446 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOptimization of Enzymatic Hydrolysis of Freeze-Dried Sea Cucumber Powder with Response Surface Methodology and Its Antioxidant EvaluationYahui Pang, Jianfeng Sun, Qian LiuIn this study, freeze-dried sea cucumber powder was used as raw material and the preparation processing conditions were studied for hydrolysis of sea cucumber powder with neutral protease using Response Surface Methodology (RSM) to obtain a high concentration of sea cucumber polypeptide. The effects of hydrolysis temperature, pH, enzyme dosage and hydrolysis time on the degree of hydrolysis (DH) were … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 17 Oct 2016 · 7,435 accessesView PDFCite
