Research ArticleOpen accessIn the abstractApplication of Newton Raphson Algorithm for Optimizing Transmission Control Protocol PerformanceJ. Viji Priya, S. SuppiahWireless networks are growing rapidly. TCP is the most widely-used protocol on Internet and so optimizing TCP performance is very important for fast efficient data transfer. The different existing TCP variants and solutions they have not been analyzed together to identify the bottlenecks in wireless networks. TCP has a major problem in its congestion control algorithm which does not allow … …Journal of Computer Science, Vol. 9, Issue 5 · 20 May 2013 · 6,302 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUsing Threads to Overcome Synchronization Delays in Parallel Multiple Progressive Alignment AlgorithmsEvandro A. Marucci, Geraldo F.D. Zafalon, Julio C. Momente et al.Problem statement: The parallelization of multiple progressive alignment algorithms is a difficult task. All known methods have strong bottlenecks resulting from synchronization delays. This is even more constraining in distributed memory systems, where message passing also delays the interprocess communication. Despite these drawbacks, parallel computing is becoming increasingly necessary to perform multiple sequence alignment. Approach: In this study, it is … …Current Research in Bioinformatics, Vol. 1, Issue 1 · 8 Mar 2012 · 14,192 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModeling of Multi-Level Capacitated Lot-Size Scheduling ProblemZuhaimy Ismail, Diyana Abd Mahad, Tan Siew ChingProblem statement: Lot-size is the clustering of items for transportation or manufacturing processes occurring at the same time. The issue in lot-size problem is to design production processes so that the feasible production quantities are equal to customer demand quantities and the timing of production is such that inventory positions are almost zero. Approach: In this study, we explore the … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,319 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimization of an Automatic Blast Furnace through Integrated Simulation ModelingAli Azadeh, S. F. GhaderiThe objective of this study was to develop an integrated simulation model of an automatic blast furnace in a full-scale steelmaking factory. The integrated simulation model introduces a set of optimizing alternatives through sensitivity analysis. The simulation model is built by considering all major and detailed operations and interacting systems of the blast furnace workshop. The workshop is composed two … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 7,092 accessesView PDF Cite
