Research ArticleOpen accessIn the abstractEfficient Simulator Based on Meta-Heuristic for FMS and AGV Systems Design and ControlSlim Ben Saoud, Amel Jaoua, Narjès Bellamine-Ben SaoudFlexible Manufacturing Systems (FMS) based on Automated Guided Vehicles (AGV) have emerged as highly competitive manufacturing technologies of the last decade. However, their design and control are complex tasks since the decision problems related to the different system parameters such as sizing and scheduling are usually shown as NP-hard. Nowadays, computer simulation is one of the most commonly used methods … …Journal of Computer Science, Vol. 1, Issue 1 · 1 Dec 2020 · 5,949 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn-silico Rational Protein Engineering and Design Approach to Improve Thermostability of a Haloalkane Dehalogenase EnzymeRaghunath Satpathy, V. Badireenath Konkimalla, Jagnyeswar RathaThermostability of enzymes is a major prerequisite for use in industrial enzymology. There are as such no simple general principles for achieving thermostability in case of enzymes as many factors are required to fulfil for different enzymes. The present study describes computational methods to design thermostable haloalkane dehalogenase enzyme using the crystal structure available Protein Data Bank (PDB ID: 1EDE). … …Current Research in Bioinformatics, Vol. 4, Issue 2 · 13 Oct 2015 · 8,279 accessesView PDFCite
Research ArticleOpen accessIn the abstractParallel Memetic Algorithm for VLSI Circuit Partitioning Problem using Graphical Processing UnitsP. Subbaraj, P. SivakumarProblem statement: Memetic Algorithm (MA) is a form of population-based hybrid Genetic Algorithm (GA) coupled with an individual learning procedure capable of performing local refinements. Here we used genetic algorithm to explore the search space and simulated annealing as a local search method to exploit the information in the search region for the optimization of VLSI netlist bi-Partitioning problem. However, … …Journal of Computer Science, Vol. 8, Issue 5 · 27 Feb 2012 · 7,090 accessesView PDFCite
Research ArticleOpen accessIn the abstractCrystal Structure of 2-(4-Hydroxy-3-Methoxyphenyl)-6- (4-Hydroxy-3-Methoxystyryl)-1-Methyl-2, 3-Dihydropyridine-4 (1H)-One by X-Ray Powder DiffractionBahjat A. Saeed, Kawkab Y. Saour, Rita S. Elias, Deng XiaodiProblem statement: The studied dihydropyridone was synthesized for the first time via the microwave assisted reaction of curcumin and methylamine and it is important to support the mechanism by the crystal structure. Approach: The crystal structure of the title compound was determined using high resolution x-ray diffraction. PowderSolve program was used to solve the structure while the refinement was done … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 7,160 accessesView PDFCite
Research ArticleOpen accessIn the abstractTakagi-Sugeno Fuzzy Gains Scheduled PI Controller for Enhancement of Power System StabilityLokman H. Hassan, M. Moghavvemi, Haider A.F. MohamedProblem statement: Power system oscillations affect system stability and may lead to failure if not properly controlled. Approach: A Takagi-Sugeno Fuzzy Gains Scheduled Proportional and Integral (FGPI) controller was proposed for a Thyristor Controlled Series Capacitor (TCSC)-based stabilizer to enhance the power system stability. Linguistic rules and fuzzy inference mechanism are utilized to tune the controller parameters on-line in different … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,541 accessesView PDFCite
Research ArticleOpen accessIn the abstractCalculation of Total Cost, Tolerance Based on Taguchi's, Asymmetric Quality Loss Function ApproachR. Sampath Kumar, N. Alagumurthi, R. RameshProblem statement: Current world market force the manufacturing sectors to develop high quality product and process design with minimum possible cost. About 80% of problems in production units may be attributed to 20% of design tolerance causes. While design typically represents the smallest actual cost elements in products (around 5%), it leverages the largest cost influence (around 70%). So design … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,045 accessesView PDFCite

Research ArticleOpen accessIn the abstractIntegrating Gene Expression Programming and Geographic Information Systems for Solving a Multi Site Land Use Allocation ProblemKhalid A. EldrandalyProblem statement: Land use planning may be defined as the process of allocating different activities or uses to specific units of area within a region. Multi sites Land Use Allocation Problems (MLUA) refer to the problem of allocating more than one land use type in an area. MLUA problem is one of the truly NP Complete (combinatorial optimization) problems. Approach: … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,849 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeuristic Algorithm in Optimal Discrete Structural DesignsAlongkorn Lamom, Thaksin Thepchatri, Wanchai RivepiboonThis study proposes a Heuristic Algorithm for Material Size Selection (HAMSS). It is developed to handle discrete structural optimization problems. The proposed algorithm (HAMSS), Simulated Annealing Algorithm (SA) and the conventional design algorithm obtained from a structural steel design software are studied with three selected examples. The HAMSS, in fact, is the adaptation from the traditional SA. Although the SA … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,345 accessesView PDFCite
