Research ArticleOpen accessIn the abstractPerformance Optimization of Physics Simulations Through Genetic AlgorithmsOksana Shadura, Federico Carminati, Anatoliy PetrenkoThe GeantV R&D approach is revisiting the standard particle transport simulation approach to be able to benefit from “Single Instruction, Multiple Data” (SIMD) computational architectures or extremely parallel systems like coprocessors and GPUs. The goal of this work is to develop a mechanism for optimizing the programs used for High-Energy Physics (HEP) particle transport simulations using a “black-box” optimization approach. … …Journal of Computer Science, Vol. 15, Issue 1 · 8 Jan 2019 · 8,091 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of the Thermodynamic Equilibrium of Fragrance Mixtures, Limonene, Linalool and Geraniol, using the Unifac and Cosmo-Sac Models and the Estimation of their Combined Properties in Binary, Ternary and Quaternary MixturesLavínia Mota Cristianismo Silva, José Izaquiel Santos da Silva, Rogério Alexandre Alves de Melo, Edilailsa Januário de MeloPerfume is a non-ideal complex mixture of chemicals originating from the extraction of essential oils and these oils are volatile components extracted from plants, some animals, or even synthesized. For this reason, to compose a fragrance, there are countless possibilities to combine one element and another, which makes the process slow and expensive. Therefore, in this study, we will combine … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 2 · 14 Jun 2022 · 7,454 accessesView PDFCite
Review ArticleOpen accessIn the abstractEducational Challenges in Computer-based Finite Element Analysis and Design of StructuresVagelis Plevris, Gro MarkesetComputer simulations and computational methods, such as the Finite Element Analysis (FEA) have become essential methodologies in science and engineering during the last decades, in a wide variety of academic fields. Six decades after the invention of the digital computer, advanced FE simulations are used to enhance and leapfrog theoretical and experimental progress, at different levels of complexity. Particularly in … …Journal of Computer Science, Vol. 14, Issue 10 · 26 Oct 2018 · 8,625 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Modeling Framework for Highway Traffic Pollution Estimation and DispersionShu Yang, Yao-Jan Wu, John WoolschlagerAir quality is of great concern to the public. Airborne pollutants, such as carbon monoxide (CO), carbon dioxide (CO2) and Particulate Matter (PM), negatively impact people’s living conditions. In particular, vehicular exhaust is a major source of these pollutants. Extensive previous research has contributed to modeling traffic pollutant emission. Popular approaches include computational simulation-based methods, which have been dominant in … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 13 May 2016 · 7,434 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 abstractIntegrating PowerWorld and MatLab for Optimal Dispatch and Unit Commitment Study of Competitive Electric Power MarketsDong Zhang, Shuhui LiThe transition to competitive wholesale and retail markets for electric utilities around the world has been a difficult and controversial process. One of the difficulties that hindered the development and growth of the competitive wholesale power market is the absence of efficient computational tools to assist the design, analysis and operation of a competitive power market. PowerWorld simulator is an … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 23 May 2015 · 7,848 accessesView PDFCite
Research ArticleOpen accessIn the abstractImplementing Mitogen Activated Protein Kinases Cascade on Membrane Computing Using P-LinguaBareq Shaalan, Ravie Chandren MuniyandiThe Mitogen Activated Protein Kinases (MAPK) cascade has been used as a case study for different computational software tools in both modelling and simulation of real-life problems. This study focuses on the development of new techniques for solving a MAPK cascade by using membrane computing. Membrane computing is an unconventional computational approach that provides a platform for modelling discrete system. … …Journal of Computer Science, Vol. 11, Issue 1 · 15 Sep 2014 · 6,815 accessesView PDFCite
Research ArticleOpen accessIn the abstractEDGE PRESERVED IMAGE COMPRESSION USING EXTENDED SHEARLET TRANSFORMS. Thayammal, D. SelvathiThe motivation of the proposed compression method is to reduce the bit rate for image transmission or memory requirement for image storage while maintaining image quality. The edges are one of the prominent features in an image and they are essential for maintaining image quality. JPEG compression standards like JPEG98 and JPEG2000 produce visual artifacts in reconstructed image at low … …Journal of Computer Science, Vol. 11, Issue 1 · 15 Sep 2014 · 7,041 accessesView PDFCite
Research ArticleOpen accessIn the abstractUSE OF COMPUTATIONAL FLUID DYNAMIC TO PREDICT AIRFLOW AND TEMPERATURE DISTRIBUTION IN A RESIDENTIAL BUILDING WITH AN UNDER FLOOR AIR DISTRIBUTION SYSTEMAbd Alnasser Almate A. Ali, Ahmed Cherif Megri, Paul A. Dellenback, Yao YuOur objective is to demonstrate the use of Computational Fluid Dynamic (CFD) in building applications. In particular, CFD has been used for temperature and airflow predictions of building spaces conditioned using Under Floor Air Distribution (UFAD) System. The space used is an instrumented laboratory room (old daycare center) located at the University of Wyoming. The use of the CFD simulation … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 11 Apr 2014 · 8,250 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE USE OF DIFFERENT LEVELS OF MULTI-ROOM MODELING APPROACH-APPLICATION TO BUILDING POLLUTION TRANSPORT AND EFFICIENCY OF OFF-HOUR VENTILATIONAhmed Cherif MegriSeveral building simulation programs have been developed for design, analysis and prediction of the distribution of temperature, airflow and heat transfer between inside and outside of a building and/or between different zones of the same building. These programs are categorized as mono-zone models, multi-room models, zonal models, Computational Fluid Dynamics (CFD) models and multi-zone models.
