Approach: Firstly, we analyse the actual data set and then we choose the finite mixture Lognormal distributions … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 16 Jan 2012 · 9,300 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Modified Gaussian Mixture Model for Color-Texture SegmentationM. Sujaritha, S. AnnaduraiProblem statement: This study presents a new, simple and efficient modified Gaussian mixture model based clustering algorithm for color-texture segmentation. The proposed mixture model introduces a new component density function which incorporates spatial information and the weighting factor for neighborhood effect is fully adaptive to the image content. Approach: It enhances the smoothness towards piecewise-homogeneous segmentation and reduces the edge-blurring … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,329 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effects of Excess Oxygen to Mixture on the Gasses Emissions of a Gasoline EngineWaleed MomaniProblem statement: The effects of excess feeding oxygen to the fuel-air mixture on the exhausts gasses emissions concentrations are investigated here. It is known that spark-ignition and diesel engines are considered as major sources of urban air pollution; such pollutants are CO2, CO, HC. Hence, many techniques have been used to decrease such emissions such as: Catalytic converters, oxidizers, traps … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,513 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCharcoal-Oil Mixture as an Alternative Fuel: A Preliminary StudyRoila Awang, Choo Yuen MayThe fast depletion of fuel oil and continuous increase in the demand for power is a global issue. The world energy consumption is projected to grow at an average of 2.7-3.7% from 1996 to 2010. Therefore search for alternative fuel is highly prioritized. Thus this study presents the results on the characteristic of charcoal-oil mixture as an alternative fuel.

Mahmood Mat Yunus, Azmi Zakaria et al.Thermal effusivity of virgin coconut oil-methanol mixtures were measured using open photoacoustic cell technique. The samples were prepared by simply mixing virgin coconut oil and methanol using similar procedure applied for preparation of biodisel. Thermal effusivity of the sample was obtained by fitting the experimental data of photoacoustic amplitude signal to the expression of photoacoustic signal as a function of … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,596 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Note on Model Selection in Mixture ExperimentsKadri Ulaş AkayIn mixture experiments, determination of the best model for modeling the mixture system is significant in both understanding and interpreting the system. For obtaining the best model in mixture experiments, different methods have been used. Most commonly used methods are the stepwise type methods. However, the models obtained with these methods are not always the best model depending on the … …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 6,939 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Use of Polyethylene in Hot Asphalt MixturesMohammad T. Awwad, Lina ShbeebThe increase in road traffic during the last two decades in combination with an insufficient degree of maintenance due to shortage in funds has caused an accelerated and continuous deterioration of the road network in Jordan. To alleviate this process, several types of measures may be effective, e.g., securing funds for maintenance, improved roadway design, use of better quality of … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 14,664 accessesView PDFCite

Literature ReviewOpen accessEvery word in the titleOptimizing the Surface-Active Performances of Cat-Anionic Mixtures: A Short ReviewCamillo A. La MesaMixtures of oppositely charged surfactants are used for applications requiring extensive foaming. This holds true for cat-anionic systems. Their bulk behavior is known in detail, when surface, or interface, properties do not attract the same attention. The thermodynamic features of such systems and the strategies interrelating the behavior in bulk to that at surfaces are outlined. Such systems are strongly … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 4 · 4 Nov 2023 · 4,931 accessesView PDFCite
