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 · 8,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulated Annealing with Deterministic DecisionsTaisir EldosProblem statement: Simulated Annealing (SA) algorithms have been used in solving a wide range of discrete optimization problems for many years, with well know drawbacks like the computational time and difficulties related to the parameters settings. One of the other issues that open the door for research is the acceptance decision that provides for hill climbing; the standard SA algorithms … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,119 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Low Complexity Lossless Coding Algorithm for Medical ImagesS. E. Ghrare, M.A. Mohd. Ali, K. Jumari, M. IsmailProblem statement: Nowadays a large number of various medical images are generated from hospitals and medical centers with sophisticated image acquisition devices, the movement toward digital images in radiology presents the problem of how to conveniently and economically store, retrieve and transmit the volume of digital images. Thus digital image data compression is necessary in order to solve this problem. … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,091 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Enhancement of Weightlifters during Snatch through Reducing Torque on Joints by Particle Swarm OptimizationFirooz Salaami, Nima Jamshidi, Mostafa Rostami, Siamak NajarianIn this research, an athlete's body on sagittal plane in tension phase of snatch weightlifting has been modeled in two dimensions for calculating the generated torques in joints. The error back propagation multi-layer perceptrons has been used for modeling the torque through changing the angular velocity, angular acceleration and absolute angle of each segment. Finally, the torque in joints has … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,101 accessesView PDFCite
Research ArticleOpen accessIn the abstractSolving Protein Folding Problem using Elitism-Based Compact Genetic AlgorithmAmr Badr, Ibtehal M. Aref, Basma M. Hussien, Yosr EmanProteins are vital components of living cells. A number of diseases such as Alzheimer's, Cystic fibrosis and Mad Cow diseases are shown to result from misfunctioning of proteins. Problem statement: Protein folding problem is the process of predicting the optimal 3D molecular structure of a protein, or tertiary structure, which is an indication of its proper function. Approach: An enhancement … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 6,856 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring Strategies for Parallel Computing of RS Data Assimilation with SWAP-GAShamim Akhter, Kiyoshi Honda, Yann Chemin, Putchong UthayopasAn agro-hydrological simulation model is useful for agriculture monitoring. One issue in running such model is parameter identification, especially when the target area is large such as provincial or country level. Remote Sensing (RS) provides us with useful information over large area. RS cannot observe input parameters of agro-hydrological models directly. However, a method to estimate input parameters of such … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 7,209 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improved Scheme for Digital Watermarking Using Functional Link Artificial Neural NetworkBanshidhar Majhi, Hasan ShalabiThe present study proposes a novel technique for copyright protection by utilizing digital watermarking of Images. The watermark is embedded and detected by using Functional Link Artificial Neural Network (FLANN) and Discrete Cosine Transform (DCT). The exhaustive simulation results of the proposed scheme show improved performance over the existing methods in all cases, i.e. when the watermarked image is subjected … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,861 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordA Survey of Quadratization Methods Used in QUBO Formulations and their Usage in Quantum and Digital AnnealingGeethika Prabhath, Anuradha Mahasinghe, Nalin Ranasinghe, Kasun De ZoysaQuantum annealing is a metaheuristic method aimed at finding the global minimum of a pseudo-Boolean quadratic function. To solve a problem by a quantum annealer, it must be restated as a QUBO (quadratic unconstrained binary optimization) problem, the standard format acceptable to an annealer. However, there are many natural problems that turn out be of cubic or higher order, yet … …Journal of Computer Science, Vol. 22, Issue 1 · 16 Feb 2026 · 2,554 accessesView PDFCite
