Effect of variable relative permittivity on the thermodynamics of asymmetric valency aqueous salts

Condensed Matter Physics
Experimentally determined empirical formulae for the concentration dependent relative permittivity of aqueous solutions of MgCl2 and NiCl2 are utilized to calculate the osmotic coefficient and the mean activity coefficient of these salts for a range of ...

Approximation of the classes $W^{r}_{\beta,\infty}$ by three-harmonic Poisson integrals

Karpatsʹkì Matematičnì Publìkacìï, 2019
In the paper, we solve one extremal problem of the theory of approximation of functional classes by linear methods. Namely, questions are investigated concerning the approximation of classes of differentiable functions by $\lambda$-methods of summation ...

Compound Poisson approximation with association or negative association via Stein's method

, 2013
In this note we show how the properties of association and negative association can be combined with Stein's method for compound Poisson approximation.

A Compound Poisson Approximation Inequality [PDF]

Journal of Applied Probability, 2006
We give conditions under which the number of events which occur in a sequence ofm-dependent events is stochastically smaller than a suitably defined compound Poisson random variable. The results are applied to counts of sequence pattern appearances and to system reliability. We also provide a numerical example.

Compound poisson approximation in systems reliability [PDF]

Naval Research Logistics, 1996
Summary: The compound Poisson ``local'' formulation of the Stein-Chen method is applied to problems in reliability theory. Bounds for the accuracy of the approximation of the reliability by an appropriate compound Poisson distribution are derived under fairly general conditions, and are applied to consecutive-2 and connected-\(s\) systems, and the 2 ...

Poisson-type approximation for sums of 1-dependent indicators

Lietuvos Matematikos Rinkinys, 2009
The sum of 1-dependent indicators is approximated by compound Poisson type distribution. Estimates are obtained for the uniform Kolmogorov and local metrics.

A non-uniform bound on Poisson approximation for a sum of negative binomial random variables [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2017
This paper uses the Stein–Chen method to determine a non-uniform bound on the point metric between the distribution of a sum of independent negative binomial random variables and a Poisson distribution with mean 1 n i i i r q     , where r i

Poisson-type approximation for sums of 1-dependent indicators

Lietuvos Matematikos Rinkinys, 2008
The sum of 1-dependent indicators is approximated by two-parametric Poisson type signed measure. Estimates are obtained for the local and total variation norms.
