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 ...
Noise pollution in the hospital environment of a developing country: A case study of Lahore (Pakistan)
(
Taylor and Francis Inc.
, 2018 , Article)
The present study investigates the noise pollution levels in public- and private-sector hospitals of Lahore. The noise pollution parameters were investigated from 20 public and 10 private hospitals. We observed that the ...
Radioactivity levels in the marine environment along the Exclusive Economic Zone (EEZ) of Qatar
(
Elsevier
, 2015 , Article)
A study on 137Cs, 40K, 226Ra, 228Ra, and 238U was carried out along the EEZ of Qatar. Results serve as the
first ever baseline data. The level of 137Cs (mean value 1.6 ± 0.4 Bq m 3) in water filters was found to be in
the ...
Isomorphic Hilbert spaces associated with different complex contours of the PT-symmetric (-x^4) theory
(
World Scientific Publishing Co.
, 2014 , Article)
In this work, we stress the existence of isomorphisms which map complex contours from the upper half to contours in the lower half of the complex plane. The metric operator is found to depend on the chosen contour but the ...
An iterative method for common solution to various problems
(
Jangjeon Mathematical Society
, 2019 , Article)
In this paper, we introduce a new iterative method to find a common solution of a generalized mixed equilibrium problem, a variational inequality problem and a hierarchical fixed point problem for demicontinuous nearly ...
Interval estimation of quantile difference in the two-parameter exponential distributions
(
ASTM International
, 2018 , Article)
We consider the interval estimation of the difference between the quantiles of two random variables with independent two-parameter exponential distributions based on Type II censored data. We derive asymptotic intervals ...
Iterative scheme for an elliptic non-local free boundary problem
(
Taylor & Francis
, 2016 , Article)
In this paper we treat a non-local free boundary problem arising in financial bubbles, where the model is set in the framework of viscosity solutions. We suggest an iterative scheme which consists of a sequence of obstacle ...
Numerical Computation of the Conformal Map onto Lemniscatic Domains
(
Springer
, 2016 , Article)
We present a numerical method for the computation of the conformal map from unbounded multiply-connected domains onto lemniscatic domains. For ℓ -times connected domains, the method requires solving ℓ boundary integral ...
Fate of accidental symmetries of the relativistic hydrogen atom in a spherical cavity
(
Elsevier Masson
, 2015 , Article)
The non-relativistic hydrogen atom enjoys an accidental SO(4) symmetry, that enlarges the rotational SO(3) symmetry, by extending the angular momentum algebra with the Runge–Lenz vector. In the relativistic hydrogen atom ...
On computing joint invariants of vector fields
(
Elsevier
, 2015 , Article)
A constructive version of the Frobenius integrability theorem-that can be programmed effectively-is given. This is used in computing invariants of groups of low ranks and recover examples from a recent paper of Boyko etal. (2009).
