Research ArticleOpen accessIn the abstractA Multiderivative Collocation Method for 5th Order Ordinary Differential EquationsS. J. Kayode, D. O. AwoyemiProblem statement: The conventional methods of solving higher order differential equations have been by reducing them to systems of first order equations. This approach is cumbersome and increases computational time. Approach: To address this problem, a numerical algorithm for direct solution of 5th order initial value problems in ordinary differential equations (odes), using power series as basis function, is proposed … …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 8,931 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Sixtic Lacunary Spline Solutions of Second Order Initial Value ProblemJwamer Karwan Hama FarajProblem statement: The lacunary problem, which we had investigated in this study, consider in finding the spline function of degree six S(x) of deficiency four, interpolating data given on the function value and third, forth order in the interval [0,1]. Also, on the extra initial condition was prescribed on the first derivative. Other purpose of this construction was to solve … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,766 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe 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 · 8,176 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Sliding Mode Command for a System of Coupled ReservoirsRiadh Gamoudi, Mahmoud Ellouze, Abdelkader MamiThis study consisted to determine a discreet order by sliding method that was applied on a regulation procedure of a formed level by communicating reservoirs. The model that represents the system is determined by parametric identification based on the algorithm of the recursive least square with forgetfulness factor. Problem statement: The purpose is to develop a robust order that assuring … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 6,555 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Order Six Zero-Stable Method for Direct Solution of Fourth Order Ordinary Differential EquationsKayode Sunday JacobA zero-stable numerical method for direct solution of fourth order differential equations reduces the computational burden and computer time wastage involved in the method of reducing such equations to a system of first order equations. The method adopted is the collocation of the differential system and the interpolation of the approximate solution to the problem using the power series as … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,177 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Prediction Model for Milling 618 Stainless Steel Using Response Surface MethodologyK. Kadirgama, K. A. Abou-El-HosseinThis study discussed the development of the first and second order power prediction model for milling 618 stainless steel with coated carbides cutting tool. The first and second order model has been developed by using response surface methodology with 4 factors. The surface methodology has been analysis by using statistical software Minitab. From the model the equation that relates the … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 7,088 accessesView PDFCite

Research ArticleOpen accessIn the abstractTasks Scheduling using Ant Colony OptimizationA. P. Shanthi, G. Umarani Srikanth, V. Uma Maheswari, Arul SiromoneyProblem statement: Efficient scheduling of the tasks to heterogeneous processors for any application is critical in order to achieve high performance. Finding a feasible schedule for a given task set to a set of heterogeneous processors without exceeding the capacity of the processors, in general, is NP-Hard. Even if there are many conventional approaches available, people have been looking at … …Journal of Computer Science, Vol. 8, Issue 8 · 25 Jul 2012 · 7,672 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Neuro Fuzzy Technique for Process Grain Scheduling of Parallel JobsS. V. Sudha, K. ThanushkodiProblem statement: We present development of neural network based fuzzy inference system for scheduling of parallel Jobs with the help of a real life workload data. The performance evaluation of a parallel system mainly depends on how the processes are co scheduled?

Research ArticleOpen accessIn the abstractMessage Based Random Variable Length Key Encryption AlgorithmHamid Mirvaziri, Kasmiran Jumari Mahamod Ismail, Zurina Mohd HanapiProblem statement: A block ciphers provides confidentiality in cryptography but cryptanalysis of the classical block ciphers demonstrated some old weaknesses grabbing a partial key in any stage of encryption procedure leads to reconstructing the whole key. Exhaustive key search shows that key generation should be indeterminist and random for each round. Matching cipher-text attack shows that larger size of block … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 6,810 accessesView PDFCite
