Research ArticleOpen accessAll words, across the recordHigher-Order Newton-Cotes FormulasPedro Americo Almeida Magalhaes Junior, Cristina Almeida MagalhaesProblem statement: The present work offers equations of Newton-Cotes Integration until twenty segments. Approach: It shows Newton-Cotes closed and open integration formulas. The new type Newton-Cotes semi-closed or semi-open was proposed. Results: An analysis of error in the technique was made. To estimate the error of integration in discrete data, we propose apply different rules or mix several rules. Conclusion/Recommendations: … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 9,750 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordComputational 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 · 6,648 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordRemoving Useless Productions of a Context Free Grammar through Petri NetMansoor Al-A'ali, Ali A. KhanFollowing the proposal for a Petri Net (PN) representation of the Context Free Grammar (CFG)[1], we propose in this paper, an algorithm to eliminate the useless productions of CFG. First the CFG is represented by a PN. Then, based on the reachability, an algorithm is developed to eliminate Useless-productions. The algorithm is analyzed and implemented in Pascal using examples of … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,670 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordJBOOM: Java Based Object Oriented Model of Software Configuration ManagementBhavya Mehta, S. K. MuttooMost of the present Software Configuration Management systems deal with version and configurations in the form of files and directories, the need today is to have a Software Configuration Management system that handles versions and configurations directly in terms of functions (program module). A major objective of this research is the use of Java in the Software Configuration Management systems. … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,888 accessesView PDFCite

The need for the tools those should be able to absorb this huge information and eliminate this problem is evident especially for IR systems. Text is not a simple sequence of words but carries a structure. It is essential to handle these uncontrollable … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,691 accessesView PDFCite
