Research ArticleOpen accessPhrase in the titleApplications of Parallel Computing for Facility Location-Transportation Problems for Disaster ResponseChansiri Singhtaun, Suriya NatsupakpongThis study extends the capability and increases the performance of a traditional Branch and Bound (BB) algorithm to solve Facility Location-Transportation problems for Disaster Response (FLTDR) using parallel computing. A Two-Stage Branch and Bound (TBB) algorithm was developed to support two parallel computing approaches. This algorithm divides problems into two small sub-problems, which are a facility location sub-problem and a … …Journal of Computer Science, Vol. 11, Issue 4 · 3 Jun 2015 · 6,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractSulfur Dioxide and Volatile Organic Compound Exposure to a Community in Texas City, Texas Evaluated Using Aermod and Empirical Monitoring DataJoyce A. Chen, Andrew R. Zapata, Anders J. Sutherland et al.According to emissions data reported to the United States Environmental Protection Agency (USEPA) and the Texas Commission on Environmental Quality (TCEQ), the BP Products North America Inc. (BP) Texas City Refinery is the worst polluter of all the industries in Texas City and is one of the worst polluting refineries in the country. The facility has reported releasing substantial emissions … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 1 Jan 2013 · 8,715 accessesView PDFCite
Research ArticleOpen accessIn the abstractDifferent Sorption Approaches and Leachate Fluxes Affecting on Mn2+ Transport through Lateritic AquiferSrilert Chotpantarat, Chakkaphan SutthiratProblem statement: Contamination of the underlying aquifer beneath a mining area is usually of great concern even when a prevention plan has been implemented. Approach: To assess the potential risk of heavy metal contamination, the simulation of heavy metal transport was carried out with different leachate fluxes and sorption parameters derived from equilibrium models with linear and Langmuir isotherms and … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 6,145 accessesView PDFCite
Research ArticleOpen accessIn the abstractIndoor Positioning System Using Artificial Neural NetworkHamid Mehmood, Nitin K. Tripathi, Taravudh TipdechoProblem statement: Location knowledge in indoor environment using Indoor Positioning Systems (IPS) has become very useful and popular in recent years. A number of Location Based Services (LBS) have been developed, which are based on IPS, these LBS include asset tracking, inventory management and security based applications. Many next-generation LBS applications such as social networking, local search, advertising and geo-tagging … …Journal of Computer Science, Vol. 6, Issue 10 · 30 Aug 2010 · 8,838 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Exact Algorithms for Rectilinear Distance Single-Source Capacitated Multi-Facility Weber ProblemsChansiri Singhtaun, Peerayuth CharnsethikulProblem statement: The objective of this study is to develop efficient exact algorithms for a single source capacitated multi-facility location problem with rectilinear distance. This problem is concerned with locating m capacitated facilities in the two dimensional plane to satisfy the demand of n customers with minimum total transportation cost which is proportional to the rectilinear distance between the facilities … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,524 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Indoor Positioning System (IPS) using Grid ModelWutjanun Muttitanon, Nitin Kumar Tripathi, Marc SourisTo date many positioning systems are available to determine or track a user's location; three main categories include Global Positioning System (GPS), wide area location system and indoor positioning system. GPS has its limitation (poor signals) in indoor or urban uses, while wide-area location systems are cellular networks dependent. For indoor positioning system many approaches like infrared sensing, radio frequency, … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 7,175 accessesView PDFCite
