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 ...
The Structure of the Free Volume in Poly(styrene-co-acrylonitrile) from Positron Lifetime and Pressure Volume Temperature (PVT) Experiments
(
WILEY-VCH Verlag
, 2004 , Article)
Summary: The structure of the free volume and its temperature dependence between 25 and 190 °C of copolymers of styrene with acrylonitrile, SAN (0 to 50 mol-% AN), is studied by pressure volume temperature (PVT) experiments ...
Inverse Adaptive Cluster Sampling with Unequal Selection Probabilities: Case Studies on Crab Holes and Arsenic Pollution
(
Wiley Publishing Asia Pty Ltd.
, 2015 , Article)
Adaptive cluster sampling is an efficient method of estimating the parameters of rare and clustered populations. The method mimics how biologists would like to collect data in the field by targeting survey effort to localised ...
On the estimation of reliabilty function in a Weibull lifetime distribution
(
Taylor & Francis
, 2008 , Article)
The estimation of the reliability function of the Weibull lifetime model is considered in the presence of uncertain prior information (not in the form of prior distribution) on the parameter of interest. This information ...
Mössbauer effect study of Li21+Me4+Fe63+O122−spinels
(
Baltzer Science Publishers, Baarn/Kluwer Academic Publishers
, 1986 , Article)
Mossbauer effect spectra are obtained for the cubic ferrites Li2 Me Fe6 O12 (where Me4+ is one of the tetravalent elements Ge, Si and Ti) at 78K up to their magnetic transition temperatures. In a rather large temperature ...
Sinc-based computations of eigenvalues of Dirac systems
(
Springer Netherlands
, 2007 , Article)
The celebrated classical sampling theorem is used to compute approximate values of the eigenvalues of Dirac systems with eigenvalue parameter in the boundary conditions. We deal with problems with an eigenparameter in one ...
One and two sample confidence intervals for estimating the mean of skewed populations: an empirical comparative study
(
TAYLOR & FRANCIS LTD
, 2009 , Article)
In this paper we consider and propose some confidence intervals for estimating the mean or difference of means of skewed populations. We extend the median t interval to the two sample problem. Further, we suggest using the ...
Error analysis associated with uniform Hermite interpolations of bandlimited functions
(
Korean Mathematical Society
, 2010 , Article)
We derive estimates for the truncation, amplitude and jitter type errors associated with Hermite-type interpolations at equidistant nodes of functions in Paley-Wiener spaces. We give pointwise and uniform estimates. Some ...
Preliminary test estimation in the two parameter exponential distribution based on record values
(
Nova Science Publishers
, 2010 , Article)
We considered estimation of the parameters of the exponential distribution based on record data in the presence of prior information. Preliminary test and shrinkage estimators are developed and their properties are ...
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 ...
