The carbon allotrope glitter as n-diamond and i-carbon nanocrystals [PDF]
Diffraction data taken from nanocrystalline n-diamond and i-carbon forms is fit to a so-called glitter model, in which the geometry of the C lattice has been optimized by density functional theory (DFT).

On the Sequential Hierarchical Cognitive Diagnostic Model
Model data fit plays an important role in any statistical analysis, and the primary goal is to detect the preferred model based on certain criteria. Under the cognitive diagnostic assessment (CDA) framework, a family of sequential cognitive diagnostic ...

Composite Goodness of Fit in Reaeration Coeffcient Modeling [PDF]
Determination of reaeration coefficient is an important factor in surface water quality modeling as it determines the efficiency of the Streeter-Phelps model used for predicting dissolved oxygen deficit of any stream. This study compared the efficiency

A New 5-Flavour LO Analysis and Parametrization of Parton Distributions in the Real Photon [PDF]
New, radiatively generated, LO quark (u,d,s,c,b) and gluon densities in a real, unpolarized photon are presented. We perform a global 3-parameter fit, based on LO DGLAP evolution equations, to all available data for the structure function F2^gamma(x,Q^2).

BACKGROUND:Many methods of spatial smoothing have been developed, for both point data as well as areal data. In Bayesian spatial models, this is achieved by purposefully designed prior(s) or smoothing functions which smooth estimates towards a local or ...

A shortcoming of least-squares unrestricted factor analysis (UFA) procedures, which are widely used in psychometric applications is that a test statistic for assessing model-data fit cannot be easily derived from the minimum fit function value. This paper proposes a chi-square type goodness-of-fit test statistic intended for the principal-axis, MINRES,
