Two-phase sample size estimation with pre-assignedvariance under normality assumption
(
Shiraz University
, 2010 , Article)
We develop a two phase sampling procedure to determine the sample size necessary to estimate the population mean of a normally distributed random variable and show that the resulting estimator has preassigned variance and ...
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.
Design/methodo ...
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 ...
