Research ArticleOpen accessIn the abstractUsing Both a Probabilistic Evolutionary Graph and the Evidence Theory for Color Scene AnalysisNassim Ammour, Abderrezak Guessoum, Daoud BerkaniIn this research, we introduce a new color images segmentation algorithm. The color scene analytic method is based on the progress of a probabilistic evolutionary graph. The strategy consists in making grow an evolutionary graph, which presents the scene elements in an unsupervised segmented image. The graph evolution development is based on the computation of the belonging probabilities to the … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,018 accessesView PDFCite
Research ArticleOpen accessIn the abstractCalculate Sensitivity Function Using Parallel AlgorithmH. A. RjoubProblem statement: To calculate sensitivity functions for a large dimension control system using one processor, it takes huge time to find the unknowns vectors for a linear system, which represents the mathematical model of the physical control system. This study is an attempt to solve the same problem in parallel to reduce the time factor needed and increase the efficiency. … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,749 accessesView PDFCite
Research ArticleOpen accessIn the abstractCollocation Discrete Least Squares (CDLS) Method for Elasticity Problems and Grid Irregularity Effect AssessmentM. Naisipour, M. H. Afshar, B. Hassani, A. R. FiroozjaeeA meshless approach, collocation discrete least square (CDLS) method, is extended in this paper, for solving elasticity problems and grid irregularity effect is assessed. In the present CDLS method, the problem domain is discretized by distributed field nodes. The field nodes are used to construct the trial functions. The moving least-squares interpolant is employed to construct the trial functions. Some … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,093 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing the Spreadsheet to Understand Random Sampling Procedures in Relation to the Central Limit TheoremRamzi Naim NasserIn many statistics courses in colleges and universities, random sampling has not been presented to students through a hands-on and practical approach. This research described a real-life method to random sampling was used as an exercise in the statistics class. The method allowed students to recursively select 5, 10, 20, 30, 40, 50, 60 and 70 samples and list these … …Journal of Mathematics and Statistics, Vol. 4, Issue 3 · 30 Sep 2008 · 6,981 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance of Unequal Error Protection Using Maximum A- posteriori Probability Algorithm and Modified MAP in Additive White Gaussian Noise and Fading ChannelT. Gnanasekaran, K. DuraiswamyProblem statement: In this study we propose a method to improve the performance of Maximum A-Posteriori Probability Algorithm, which is used in turbo decoder. Previously the performance of turbo decoder is improved by means of scaling the channel reliability value. Approach: A modification in MAP algorithm proposed in this study, which achieves further improvement in forward error correction by means … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 6,689 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeterministic Parallel Sorting Algorithm for 2-D Mesh of Connected ComputersHamed Al Rjoub, Arwa Zabian, Ahmad OdatSorting is one of the most important operations in database systems and its efficiency can influences drastically the overall system performance. To accelerate the performance of database systems, parallelism is applied to the execution of the data administration operations. We propose a new deterministic Parallel Sorting Algorithm (DPSA) that improves the performance of Quick sort in sorting an array of … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,825 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of Vehicle Flows and Emissions for Various Scenarios of Street Network Modifications in Mexico CityAngelica Lozano, Francisco Granados, Juan Pablo AntunWe estimate flows and emissions (NOx, HC, CO) generated by vehicles circulating on the main streets of the Mexico City Metropolitan Area. The estimation is made for various scenarios, which include a set of changes to the street network for current and future horizons. These changes encompass the construction of new arcs or improvement of existing arcs. Network flows are … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 6,215 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Microscopic Study of Language-Related Cortex in AutismEdith López-Hurtado, Jorge J. PrietoImpaired language function is a principle criterion for the diagnosis of autism. The present study of brain from age-matched autistic and control subjects compared brain regions associated with the production and processing of speech. Wernicke's area (Brodmann 22, speech recognition), Broca's area (Brodmann 44, speech production) andthe gyrus angularis (Brodmann 39, reading) from autistic subjects (7-44 years of age) and … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 8,547 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrostructural Study of Al-Si-Mg Alloy Reinforced with Stainless Steel Wires Composite via Casting TechniqueMazlee Mohd. Noor, Shamsul Baharin Jamaludin, Kamarudin HussinThe microstructural study of Al-Si-Mg alloy reinforced with stainless steel wires (Al-Si-Mg/SSw) has been investigated and focused on the both microstructures in the matrix and near to the interface and also the wetting condition at the interface. The wettability of solid metals by liquid metals is very important in determining the needed properties of the composite systems. In this study, … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 6,655 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputational Discrete Time Markov Chain with Correlated Transition ProbabilitiesPeerayuth CharnsethikulThis study presents a computational procedure for analyzing statistics of steady state probabilities in a discrete time Markov chain with correlations among their transition probabilities. The proposed model simply uses the first order Taylor’s series expansion and statistical expected value properties to obtain the resulting linear matrix equations system. Computationally, the bottleneck is O(n4) but can be improved by distributed … …Journal of Mathematics and Statistics, Vol. 2, Issue 4 · 31 Dec 2007 · 6,650 accessesView PDFCite
