LohProblem statement: Southern Waste Management environment (SWM environment) is a company responsible for the collection and disposal of solid waste for the city of Johor Bahru, a city with over one million populations. The company is implementing an integrated solid waste management system where it involved in the optimization of resources to ensure the effectiveness of its services. Formulating this … …Journal of Mathematics and Statistics, Vol. 5, Issue 3 · 30 Sep 2009 · 8,020 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAttitudes of Sultan Qaboos University Students towards Some Environmental Problems and their Willingness to Take Action to Reduce themAhmed Bin Hamad Al-Rabaani, S. S. Mohammed Al-MekhlafiProblem statement: Our earth suffers from many environmental problems which need to be tackled at the individual level, requiring individuals to develop those attitudes which will guide them to environmentally supportive behavior. The objectives of this study were to investigate (i) the attitudes of Sultan Qaboos University students to some environmental problems, (ii) their willingness to take action to ameliorate … …Journal of Social Sciences, Vol. 5, Issue 1 · 31 Mar 2009 · 8,835 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSpeedup of Particle Transport Problems with a Beowulf ClusterZhongxiang Zhao, G. Ivan MaldonadoThe MCNP code is a general Monte Carlo N-Particle Transport program that is widely used in health physics, medical physics and nuclear engineering for problems involving neutron, photon and electron transport[1]. However, due to the stochastic nature of the algorithms employed to solve the Boltzmann transport equation, MCNP generally exhibits a slow rate of convergence. In fact, engineers and scientists … …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Dec 2006 · 6,923 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGuerrilla Marketing Communication Tools and Ethical Problems in Guerilla AdvertisingCanan Ay, Pinar Aytekin, Sinan NardaliProblem statement: Companies attempt to reach private worlds of consumers and give them memorable experience with their brands by using guerrilla marketing tools. Guerrilla advertising, which is one of the guerrilla marketing tools, usually attracts the attention of consumers but sometimes irritates and annoys the consumers and even breaks the law. Approach: The study determined these ethical aspects by evaluating … …American Journal of Economics and Business Administration, Vol. 2, Issue 3 · 30 Sep 2010 · 22,520 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Laboratory Study of Bayesian Updating in Small Feedback-Based Decision ProblemsTakemi Fujikawa, Sobei H. OdaThis study explores small feedback-based decision problems experimentally. Conducted were the experiments in which the decision-maker’s payoff distribution was limited to either favorable distribution or unfavorable distribution. The first remarkable observation revealed complexity/loss aversion in the experiment. The second observation included the law of small numbers. Deviations from maximization were also observed. Finally, we investigated the imperfect Bayesian decision-makers observed … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,760 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleConjugate Gradient ‎Method: A Developed Version to Resolve Unconstrained Optimization ProblemsAhmad Alhawarat, Nguyen-Thoi Trung, Zabidin SallehOne of the important methods that are widely utilized to resolve ‎unconstrained ‎optimization problems is the Conjugate Gradient (CG) method. This paper aims to propose a new version of the CG method on the basis of Weak Wolfe-Powell (WWP) line search. The assumption is bounded below optimization problems with the Lipschitz continuous gradient. The new parameter obtains global convergence properties … …Journal of Computer Science, Vol. 16, Issue 9 · 18 Sep 2020 · 6,894 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlep ≠ np: The Set of Deterministic Problems that are Solvable in Polynomial Time is Unequal to the Set of Non-Deterministic Problems that are Solvable in Polynomial TimeAndres BoldoriThis study constructs a solution to the “p vs. np” problem using complexity theory. We show through counterexamples that p ≠ np and formalize the two sets using stochastic, probabilistic and non-deterministic modeling. While the well-known sets “pspace” and “npspace”, analyzing the storage of a device, can be claimed to be equal, p and np differ and are exclusively defined … …Journal of Computer Science, Vol. 20, Issue 10 · 8 Aug 2024 · 7,112 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleE-Saddle Point Criteria for E-differentiable Vector Optimization Problems with Inequality and Equality ConstraintsTadeusz Antczak, Najeeb Abdulaleemn this study, the class of E-differentiable vector optimization problems with both inequality and equality constraints is considered. For such (not necessarily) differentiable multicriteria optimization problems, two E-Lagrange functions and their E-saddle points are defined. Then the so-called E-saddle point criteria are established for such (not necessarily) differentiable multiobjective programming problems with E-differentiable E-convex functions. …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 11 May 2019 · 7,407 accessesView PDFCite
Research ArticleOpen accessEvery word 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 · 6,658 accessesView PDFCite
