Analysis of particulate behavior in porous media
(
Shanghai University Press
, 2008 , Article)
In this work, we analyze the behavior of the particle phase in the flow of a particle-laden mixture through a porous medium. An attempt is made to model the diffusion and dispersion processes, and to quantify the deviation ...
Mössbauer study of ZnxNi5/3−xFe1Sb1/3O4 spinel ferrite
(
Springer Verlag
, 1985 , Article)
The antimony substituted nickel ferrite ZnxNi5/3–xFe1Sb1/3O4 with different values ofx are prepared, checked by x-ray and studied with57Fe Mössbauer spectroscopy over a wide temperature range. Characteristic spectra of ...
Regression estimator under inverse sampling to estimate arsenic contamination
(
John Wiley & Sons, Ltd
, 2011 , Article)
The fate of arsenic introduced to the environment as a result of the natural and human activities is an important issue. Surveys of arsenic typically involve sampling from a large area. Measuring arsenic concentrations in ...
Outlier robust nonlinear mixed model estimation
(
John Wiley & Sons, Ltd.
, 2015 , Article)
In standard analyses of data well-modeled by a nonlinear mixed model, an aberrant observation, either within a cluster, or an entire cluster itself, can greatly distort parameter estimates and subsequent standard errors. ...
Dark solitons near potential and nonlinearity steps
(
American Physical Society
, 2016 , Article)
We study dark solitons near potential and nonlinearity steps and combinations thereof, forming rectangular barriers. This setting is relevant to the contexts of atomic Bose-Einstein condensates (where such steps can be ...
High prevalence of the risk of overweight and overweight among Qatari children ages 9 through 11
(
Emerald
, 2009 , Article)
Purpose – The purpose of this paper is to estimate the prevalence of the risk of overweight and
overweight in Qatari children ages 9 through 11 and to compare the prevalence using CDC and IOTF
cut-offs.

Temperature dependence of the pressure induced monoclinic distortion in the spin S=1/2 Shastry–Sutherland compound SrCu2(BO3)2
(
Elsevier Ltd
, 2014 , Article)
We investigate the monoclinic distortion that occurs at 4.7 GPa at room temperature in the frustrated Shastry-Sutherland model quantum magnet SrCu 2(BO3)2 as a function of pressure and temperature by means of powder and ...
LQ (optimal) control of hyperbolic PDAEs
(
Taylor and Francis Ltd.
, 2014 , Article)
The linear quadratic control synthesis for a set of coupled first-order hyperbolic partial differential and algebraic equations is presented by using the infinite-dimensional Hilbert state-space representation of the system ...
On convergence of an implicit iterative algorithm for non self asymptotically non expansive mappings
(
Hacettepe University
, 2014 , Article)
In this paper, we study an implicit iterative algorithm for two nite families of nonself asymptotically nonexpansive mappings. We prove some weak and strong convergence theorems for this iterative algo- rithm. Our results ...
Multivariate multilevel models for attitudes toward statistics: multi-disciplinary settings in Afghanistan
(
Taylor & Francis
, 2016 , Article)
The present paper focuses on examining students' attitudes and perception of statistics in Afghanistan universities and the factor structure of the statistical anxiety rating scale (STARS). In total, 209 undergraduate ...
