Research ArticleOpen accessEvery word in the titleSimulation Planning for Sustainable Use of Land Resources: Case study in DiamouDiallo Yacouba, Hu Guangdao, Abdurazak Hussien AbdulahiIn this study, we presented the simulation planning scheme to project land and land resources use changes at a local scale for Diamou (MALI). Problem statement: All the land cover types were under the influence of human and livestock population. Diamou has undergone changes in land-cover over the last decades. The shifting cultivation system practiced was probably the main reason … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 7,663 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReal-Time Simulation Method Using Monte Carlo and Clustering Algorithms: A Case Study Covering Drill Bit WearRodolfo Wilvert Reitz, Paulo José de Freitas FilhoMinimization of the cost of drilling an oil well is primarily achieved by reducing the operation completion time, which in turn can be achieved by increasing the Rate of Penetration (ROP). The ROP is the result of a combination of factors, such as lithological formation, operational parameters and bit wear. This paper addresses bit wear during drilling, using a method … …Journal of Computer Science, Vol. 14, Issue 2 · 27 Feb 2018 · 8,217 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStudy of Au/n-Ti2S/p-Si/Al Schottky-Type Thin Film Heterojunction Solar Cells: Computer Simulation ModelingAli IbrahimThe Au/n-Ti2S/p-Si/Al heterojunction with intrinsic thin-layer solar cells were analyzed by AFORS-HET software program. Thickness of the emitter intrinsic layer and the interface state density of such cells were studied. In which, the intrinsic layer inserted between the Ti2S and crystalline p-type silicon substrate, reduce the interface state density. The thinner intrinsic layer is better than thicker one, when the … …American Journal of Applied Sciences, Vol. 12, Issue 4 · 3 Jun 2015 · 6,284 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Frame Study for Post-Processing Analysis on System Behavior: A Case Study of Deadline Miss DetectionJunghee Lee, Jongman KimProblem statement: A lot of data can be obtained by system simulation using transaction level models without affecting the performance of the system. Due to huge amount of the raw data, we often need to post-process them to extract valuable information. Profiling capabilities of commercial tools provide predefined functionalities and don’t allow users to add or modify for their own … …Journal of Computer Science, Vol. 6, Issue 12 · 22 Nov 2010 · 6,746 accessesView PDFCite
Research ArticleOpen accessIn the keywordsConfidence Intervals for Signal to Noise Ratio of a Poisson DistributionFlorence George, B.M. Golam KibriaThe Poisson distribution is one of the most useful probability distributions to fit rare event data. Confidence interval for the SNR is an important issue among the researchers in image processing. This study considers several confidence intervals for the SNR of a Poisson distribution. Different confidence intervals available in literature are reviewed and compared based on the coverage probability and … …Current Research in Biostatistics, Vol. 2, Issue 2 · 19 Sep 2012 · 13,914 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Test for Two-Sample Repeated Measures Designs: Effect of High-Dimensional DataBoonyarit Choopradit, Samruam ChongcharoenProblem statement: High-dimensional repeated measures data are increasingly encountered in various areas of modern science since classical multivariate statistics, e.g,. Hotelling’s T2, are not well defined in the case of high-dimensional data. Approach: In this study, the test statistics with no specific form of covariance matrix for analyzing high-dimensional two-sample repeated measures designs with common equal covariance are proposed. The … …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 28 Oct 2011 · 7,332 accessesView PDFCite
