Research ArticleOpen accessEvery word in the titleDetermination of Atmospheric Turbidity and its Correlation with Climatologically ParametersU. Ali Rahoma, A. H. HassanStudy of Atmospheric turbidity is important for purposes of meteorology, ecology, climatology and monitoring of atmospheric pollution. Linke Turbidity factor (LT) is commonly used to model the attenuation of solar radiation in the atmosphere. The probable dependence on the water vapor content of the relationship linking LT to Angstrom’s turbidity coefficient B, is discussed. In this study, a procedure for … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 28 Dec 2012 · 6,986 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComputational and Statistical Analysis of Security and Privacy Parameters of Cloud Computing in Information TechnologyJimbo Claver, Edris Hamraz, Takeru Suzuki et al.Information Technology has transformed the way cloud computing itself can help to manage, consume and improve cost efficiencies, accelerate innovation, provide faster time to the market and develop the ability to scale applications on demands and services. In this research work, we present recent developments and some statistical analysis techniques used in cloud computing development with challenges related to the … …Journal of Computer Science, Vol. 16, Issue 11 · 24 Nov 2020 · 7,269 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleKRYLOV’S SUBSPACES ITERATIVE METHODS TO EVALUATE ELECTROSTATIC PARAMETERSMario Versaci, Alessandra Jannelli, Giovanni Angiulli, Francesco Carlo MorabitoMost of the electromagnetic problems can be stated in terms of an inhomogeneous equation Af = g in which A is a differential, integral or integro-differential operator, g in the exitation source and f is the unknown function to be determined. Methods of Moments (MoM) is a procedure to solve the equation above and, by means of an appropriate choice … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 4 Jan 2014 · 7,867 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Heat Treatment Parameters on Distribution and Volume Fraction of Mg2Si in the Structural Al 6063 AlloyG. Al-MarahlehAluminum Profiles -Production by extrusion from aluminum billets require a certain degree of homogeneity because of the segregated second phase particles, which are available in the as cast structure of the billets. Worldwide practice suggests a long homogenizing process at elevated temperatures in order to achieve such condition. This study showed that profiles extruded from homogenized and unhomogenized billets did … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 8 May 2006 · 7,783 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGeneralized Statistical Inference for Quantiles of Two-Parameter Gamma DistributionMalwane AnandaGamma distribution is a widely used distribution to analyze data in many disciplines such as hydrology, meteorology, environmental monitoring, lifetime testing and reliability. In this study, we look at the statistical inference for the quantiles of two-parameter gamma distribution. The testing and estimation of gamma quantile are required especially in areas such as flood frequency analysis and life testing. For … …Journal of Mathematics and Statistics, Vol. 20, Issue 1 · 12 Feb 2024 · 5,910 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleParameter Measurement and Calibration in Discrete Element Simulation of Broken Sweet Potato SeedlingsGuizhi Mu, Xieteng Qi, Wangzhi Zhang et al.Given the lack of accurate parameter values in discrete element simulation of sweet potato seedling mechanized recovery, a direct measurement and virtual calibration method was used to study the Discrete Element Method (DEM) simulation parameters of broken sweet potato stems and leaves. The intrinsic parameters, collision recovery coefficient and static friction coefficient of broken seedlings were acquired by physical experiments. … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 8 Jun 2021 · 6,369 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSEQUENTIAL ESTIMATION OF THE SQUARE OF THE RAYLEIGH PARAMETERMohamed TahirThe problem addressed is that of sequentially estimating the square of the parameter of the Rayleigh distribution, subject to a weighted squared loss plus cost of sampling. We propose a sequential procedure and provide a second-order asymptotic expansion for the incurred regret. It is seen that the asymptotic regret is negative for a range of values of the parameter. …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 19 Jun 2014 · 6,439 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMATERIAL PARAMETER OF RUBBER GLOVE VULCANIZED USING COMBINED INFRARED AND HOT-AIR HEATINGTipapon Khamdaeng, Numpon Panyoyai, Thanasit WongsiriamnuayVulcanization is an important chemical-thermal process in production of rubber products resulting in change of material properties, increased elasticity and strength. In general, Young’s modulus is used as an indicator of elastic deformation at loading configuration. However, rubber is not truly elastic and a single parameter is insufficient to describe the whole deformation contributed by microstructure of rubber network. Therefore, … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 8 Feb 2014 · 7,305 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMODERATING ABILITY OF ITEM RESPONSE THEORY THROUGH PRIOR GUESSING PARAMETERSiow Hoo Leong, Siew Eng Ling, Rasidah MahdiA psycho-technology approach to discouraging guessing in multiple-choice formatted item can be done through reducing the a priori guessing probability of an item. This study proposes a psychometrics framework of Item Response Theory (IRT) to model the effect of having various priori guessing probabilities across different items. A prior guessing parameter is proposed to serves as a moderator of the … …Journal of Mathematics and Statistics, Vol. 9, Issue 4 · 26 Sep 2013 · 7,116 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleParameter Estimation and Determination of Sample Size in Logistic RegressionAdeleke Kazeem Adedayo, Dawud Adebayo AgunbiadeThe determination of Sample-Size is often an important step in planning a statistical study and it is usually a difficult task. Among the important hurdles to be surpassed, one must obtain an estimate of one or more error variances and specify an effective sample size of importance. The study was carried out to check for the estimation of parameter and … …Journal of Mathematics and Statistics, Vol. 8, Issue 4 · 4 Feb 2013 · 6,915 accessesView PDFCite
