Research ArticleOpen accessIn the keywordsHill Climbing Method Using Claus Model for Categorical DataB. OnoghojobiProblem statement: In this study, a locally unbiased test statistic based on the Claussian method was presented. Approach: In this respect, exploiting special structures of modified quadratic hill climbing method and the Claussian statistics were considered. Results: We derived a non-modified quadratic hill-climbing procedure. The performance of the model in testing the estimation of Latent data was shown. Conclusion/Recommendations: The … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,298 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNexus between CO2 Emission, Energy Consumption and Economic Growth in ASEAN Countries Plus ChinaGhulam Mustafa, Ismail Abd Latif, Said Zamin Shah, Muhammad Khalid BashirThis study mainly contributes to test the Environmental Kuznets Curve (EKC) hypothesis using panel data for the ASEAN (Malaysia, Indonesia, Thailand and Philippines) countries plus China. Empirical focus of the study is to examine the nexus between CO2 emission, energy consumption and economic growth. While using panel data for 1971-2008 and applying panel co-integration techniques, the emergent findings of the … …American Journal of Environmental Sciences, Vol. 12, Issue 4 · 19 Aug 2016 · 7,856 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA New Separable Logarithmic Algorithm for Non-Linear OptimizationAbbas Y. Al-Bayati, Hawraz N. JabbarProblem statement: The idea of this study stemmed from the fact that most of the currently used optimization algorithms use a local quadratic representation of the objective function. It also arisen from the fact that the objective function may not be represented adequately by quadratic functions and the global minimizer may be obtained for objective functions. So, in this study, … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 6,872 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Extraction and Fractionation Period on the Yield of a Tropical Peat Soil (Hemists) Humic AcidsSusilawati Kasim, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Khanif YusopThe isolation of humic acids from soils is laborious and time consuming. Factors that affect the yield of humic acids isolated from soils include extraction, fractionation and purification periods. This study was conducted to investigate whether a relationship could be separately established between extraction time, fractionation time, and the yield of humic acids of a tropical peat soil (Hemists), as … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 8,099 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Linear and Quadratic Nature of Sequences for Determining Prime Numbers by Elimination of CompositesJonathan M. Dugas, Brian M. O’ConnorA previously derived set of sequences for generating prime numbers is modified by various algebraic and trigonometric manipulations. The modified sequences are then used to more efficiently generate prime numbers. The modified sequences are simplified from their original form and are much easier to implement into a computer program. It is shown by computation that the modified sequences more efficiently … …Journal of Mathematics and Statistics, Vol. 14, Issue 1 · 16 May 2018 · 7,405 accessesView PDF Cite
