Asymptotic formulae for eigenvalues and eigenfunctions of q-Sturm-Liouville problems
(
WILEY-VCH Verlag
, 2011 , Article)
We investigate the asymptotic behavior of the eigenvalues and the eigenfunctions of q-Sturm-Liouville eigenvalue problems. For this aim we study the asymptotic behavior of q-trigonometric functions as well as fundamental ...
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 ...
Adaptive and unequal probability survey designs for environmental management
(
The Modelling and Simulation Society of Australia and New Zealand Inc
, 2011 , Conference Paper)
Designing an efficient large-area survey is a challenge, especially in environmental science when many populations are rare and clustered. Adaptive and unequal probability sampling designs are appealing when populations ...
Multi-species attributes as the condition for adaptive sampling of rare species using two-stage sequential sampling with an auxiliary variable
(
The Modelling and Simulation Society of Australia and New Zealand Inc
, 2011 , Conference Paper)
Assessing populations of rare species is challenging because of the large effort required to locate patches of occupied habitat and achieve precise estimates of density and abundance. The presence of a rare species has ...
Use of post-stratification in composite sampling for estimating mean
(
Springer
, 2011 , Article)
We show with the results of a study conducted in the Hamadan Province, Iran as to how the use of composite sampling for estimating mean zinc concentration in the soil can help reduce analytical costs by reducing the number ...
Inference in simple regression for the intercept utilizing prior information on the slope
(
Wayne State University
, 2011 , Article)
Shrinkage type estimators are developed for the intercept parameter of a simple linear regression model and the case when it is suspected a priori that the slope parameter is equal to some specific value is considered. ...
Empirical likelihood inference for population quantiles with unbalanced ranked set samples
(
Taylor & Francis Group
, 2011 , Article)
We consider nonparametric interval estimation for the population quantiles based on unbalanced ranked set samples. We derived the large sample distribution of the empirical log likelihood ratio statistic for the quantiles. ...
Antihydrogen physics: Gravitation and spectroscopy in AEgIS
(
Canadian science publishing
, 2011 , Article)
AEgIS (Antimatter experiment: gravity, interferometry, spectroscopy) is an experiment approved by CERN with the goal of studying antihydrogen physics. In AEgIS, antihydrogen will be produced by charge exchange reactions ...
Measuring the fall of antihydrogen: The AEGIS experiment at CERN
(
Elsevier B.V.
, 2011 , Conference Paper)
Considerable efforts have been made and are still being made to verify the validity of the principle of the equivalence of gravitational and inertial mass, one of the cornerstones of the classical theory of general relativity. ...
On the boundedness of a class of rough maximal operators on product spaces
(2011 , Article)
In this paper, we study the Lp boundedness of a class of maximal operators T (γ) {Ωj} and a related class of rough singular integrals on product spaces. We obtain appropriate Lp estimates for such maximal operators and ...
