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 · 6,654 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleApplying Information Theory Analysis for the Solution of Biomedical Data Processing ProblemsDavid Blokh, Ilia StamblerThe use of information-theoretical methods can be highly valuable for the solution of biomedical data processing problems. Some of the problems that can be solved by those methods include: The assessment of the influence of diagnostic parameters, biomarkers and risk factors, on the emergence of disease; the discretization of diagnostic parameters; the analysis of a combined influence of a group … …Current Research in Bioinformatics, Vol. 3, Issue 1 · 13 Jan 2015 · 9,631 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Cryptosystem Based on Factoring and Discrete Logarithm ProblemsE.S. Ismail, M.S.N. HijaziProblem statement: A cryptosystem allows a sender to send any confidential or private message using a receiver’s public key and later the receiver confirms the integrity of the received message using his secret key. Currently the existing cryptosystems were developed based on a single hard problem like factoring, discrete logarithm, residuosity, knapsack or elliptic curve discrete logarithm. Although these schemes … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 18 Jul 2011 · 7,786 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Existence, Uniqueness and Error Bounds of Approximation Splines Interpolation for Solving Second-Order Initial Value ProblemsAbbas Y. Al Bayati, Rostam K. Saeed, Faraidun K. Hama-SalhProblem statement: The lacunary interpolation problem, which we had investigated in this study, consisted in finding the six degree spline S(x) of deficiency four, interpolating data given on the function value and third and fifth order in the interval [0,1]. Also, an extra initial condition was prescribed on the first derivative. Other purpose of this construction was to solve the … …Journal of Mathematics and Statistics, Vol. 5, Issue 2 · 30 Jun 2009 · 8,172 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Experimental Study of Petty Corrupt Behaviour in Small Decision Making ProblemsTakemi FujikawaThis research discusses small decision making problems and petty corruption as their practical applications with a structured economic experiment. One of examples of petty corruption considered includes demands for petty bribes by traffic officials followed by police. We examine that it is caused by subjective underweighting of rare events and its objective probabilities. This literature reports results of an experiment, … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 3 Dec 2005 · 8,105 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumerical Solution of First Order Initial Value Problems Using a Self-Starting Implicit Two-Step Obrechkoff-Type Block MethodZurni Omar, Oluwaseun AdeyeyeThe conventional two-step implicit Obrechkoff method is a discrete scheme that requires additional starting values when implemented for the numerical solution of first order initial value problems. This paper therefore presents a two-step implicit Obrechkoff-type block method which is self-starting for solving first order initial value problems, hence bypassing the rigour of developing and implementing new starting values for the … …Journal of Mathematics and Statistics, Vol. 12, Issue 2 · 13 Jun 2016 · 8,078 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePlacebo-Driven Clinical Trials of Transfer Point Glucan #300 in Children with Chronic Respiratory Problems: III. Clinical FindingsVetvicka Vaclav, Richter Josef, Svozil Vladimir et al.The role of glucan in stimulation of immune reactions has been studied for decades. In this report we focused on the effects of orally administered glucan in children with chronic respiratory problems. We measured the physical endurance using a 6MWT test and the levels of eNO in 50 children aged 8-12 years and evaluated the effects of 100 mg/d oral … …American Journal of Immunology, Vol. 9, Issue 3 · 20 Aug 2013 · 9,028 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePlacebo-Driven Clinical Trials of Transfer Point Glucan #300 in Children with Chronic Respiratory Problems: Antibody ProductionVetvicka Vaclav, Richter Josef, Svozil Vladimir et al.The role of glucan in stimulation of immune reactions has been well-established. In this report, we focused on the antibody production in glucan-supplemented children with chronic respiratory problems. We measured the levels of salivary IgA, IgM and IgG in 40 children aged 8-12 years and evaluated the effects of 100 mg d-1 oral dose of glucan. We found a significant … …American Journal of Immunology, Vol. 9, Issue 2 · 5 Jun 2013 · 10,462 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Novel Ensemble Method for Regression via Classification ProblemsSami M. Halawani, Ibrahim A. Albidewi, Amir AhmadProblem statement: Regression via Classification (RvC) is a method in which a regression problem is converted into a classification problem. A discretization process is used to covert continuous target value to classes. The discretized data can be used with classifiers as a classification problem. Approach: In this study, we use a discretization method, Extreme Randomized Discretization (ERD), in which bin … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 7,383 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProducing Television Agriculture Program: Issues and Problems among Malaysian Television ProducersMd. Salleh Hassan, Hayrol Azril Mohamed Shaffril, Bahaman Abu Samah et al.Problem statement: One of the developing sectors in Malaysia is agriculture. Agriculture doubtlessly has assisted this country in terms of enhancing the economic level, offering a huge number of employment opportunities and uplifting the socio-economy status of the community.
