Research ArticleOpen accessAll words, across the recordPerformance Comparison of Active Queue Management TechniquesT. B. Reddy, A. AhammedCongestion is an important issue which researchers focus on in the Transmission Control Protocol (TCP) network environment. To keep the stability of the whole network, congestion control algorithms have been extensively studied. Queue management method employed by the routers is one of the important issues in the congestion control study. Active Queue Management (AQM) has been proposed as a router-based … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,193 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 recordConformational Analysis of Trans-3, 6-Dibutanal-1, 2, 4, 5-TetroxaneEduardo A. Castro, Mariela I. Profeta, Jorge M. Romero et al.We report the results of theoretical semiempirical AM1 and PM3 molecular orbital methods on the conformational analysis of the title compound. The relative stability of different isomers and conformers are discussed on the basis of well defined electronic and steric effects, which are rather helpful in order to understand the relative stabilities. …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,695 accessesView PDFCite
