Research ArticleOpen accessEvery word in the titleTHE RATE FUNCTION OF S-MIXING PROCESS AND ITS APPLICATION IN EVALUATING EMPIRICAL LIKELIHOOD TESTSXing WangIn this study we show that the rate function of S-Mixing stationary process with part of the hypermixing condition is equivalent to the Kullback-Leibler distance. This finding can be used to extend the result of the optimality of empirical likelihood test in i.i.d setting to weakly depended case, so that the Asymptotic Relative Efficiency (ARE) of the empirical likelihood test … …Journal of Mathematics and Statistics, Vol. 9, Issue 4 · 28 Oct 2013 · 6,615 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImpact of Four Wave Mixing (FWM) in Routing and Wavelength AssignmentTan Saw Chin, F.M. Abbou, Ewe Hong TatThe impact of Four-Wave-Mixing (FWM) is investigated using the proposed Assign Shortest Path First (ASPF) algorithm for wavelength assignment in Routing and Wavelength Assignment (RWA). Results show that ASPF algorithm indulges more FWM crosstalk in high optical channels for all input light power and low input power able to reduce he effect of FWM. The blocking probability due to FWM … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,753 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Mixing on the Biological Degradation of Toluene under Aerobic ConditionsAbdel E. Ghaly, D.G. Rushton, K. MartinellThe effectiveness of in-vessel bioremediation in reducing the concentration of toluene in contaminated soil under continuous and intermittent mixing conditions using invessel composting system. The results showed that there was a startup period (60 h) during which the average temperature rose from 21 to 32 and 40°C (and then remained constant) for the bioreactors with continuous and intermittent mixing, respectively. … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,497 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMixing Patterns and Residence Time Determination in a Bubbling Fluidized Bed SystemA. E. Ghaly, K. N. MacDonaldFluidized bed gasification can be used to convert the solar energy stored as carboneous compounds in biomass into a carbon neutral fuel with reduced emissions. Canada produces 20.57 million tonnes of wheat straw annually which could be used for green energy production. Wheat straw residue gasification has the capability of replacing 7.5 % (0.62 EJ) of Canada’s annual fossil fuel … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 17 Aug 2012 · 8,115 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Mixing Ratio and Size of Egg-Shell on Boiling and Compression Test of Mixed CharcoalBopit Bubphachot, Rujipas Seeladlao, Songchai WiriyaumpaiwongProblem statement: The use of waste material is one of the options to add value to the residue. Nowadays, solid fuel development is necessary in current situation due to high price fossil fuel and the reduction of resource. Wood charcoal is widely used in the country which has abundant of forest. Becoming charcoal, it needs to be burnt under optimum … …Energy Research Journal, Vol. 1, Issue 1 · 30 Jun 2010 · 8,644 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReducing Ammonia Loss from Urea by Mixing with Humic and Fulvic Acids Isolated from CoalAmeera Abdul Reeza, Osumanu Haruna Ahmed, Nik Muhamad Nik Ab. Majid, Mohamadu Boyie JallohProblem statement: Ammonia volatilization is a major pathway for nitrogen loss from surface applied urea. While all top-dressed ammonia and ammonium based N fertilizers can volatilize, the potential loss is greatest with urea and fluids containing urea. As much as 20-50% of N applied to soils is lost through volatilization alone. Thus, the objective of this laboratory study was to … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 10,897 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReduction of Ammonia Loss from Urea through Mixing with Humic Acids Isolated from Peat Soil (Saprists)Regis Bernard, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Application of urea as a source of nitrogen fertilizer has an adverse effect on ammoniacal loss to the environment. This study was conducted to reduce ammonia loss from urea by mixing with Humic Acids (HA) isolated from Saprists peat. Approach: The effects of urea amended with four different amounts of humic acids, 0.25, 0.50, 0.75 and 1.00 g … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,846 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReduction of Ammonia Volatilization through Mixing Urea with Humic and Fulvic Acids isolated from Palm Oil Mill Effluent SludgeShamsuddin Rosliza, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Ammonia volatilization from surface-applied urea may be substantial but it is possible to control it by mixing urea with acidic substances such as Humic Acids (HA) and Fulvic Acids (FA). The objective of this study was to compare the effects of urea-HA, urea-FA, urea-acidified (HA+FA) mixtures on ammonia loss, soil pH, soil exchangeable ammonium and available nitrate accumulation … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,350 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExperimental Evaluation of Anti-Stripping Additives Mixing in Road Surface Pavement MaterialsTienfuan Kerh, Yu-Min Wang, Yulern LinMost road surfaces in Taiwan are paved with asphalt concrete but the phenomena of rutting, cracking and stripping of the pavement are frequently occurring due to the effects of traffic flow, thermal variation and water erosion caused by rain. In this study, a series of experiments were performed to examine the effectiveness of anti-stripping fillers, which include; rock flour, rock … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,911 accessesView PDFCite
