Higher order Hamiltonian fluid reduction of Vlasov equation [PDF]

open access: yes, 2014
From the Hamiltonian structure of the Vlasov equation, we build a Hamiltonian model for the first three moments of the Vlasov distribution function, namely, the density, the momentum density and the specific internal energy. We derive the Poisson bracket

INVESTIGATING POPULATION BALANCE IN THE STATE OF GEORGIA USING SPATIAL CLUSTERING [PDF]

open access: yesریاضی و جامعه
Identification of population ratio disruption in the population structure is one of the challenges that every country faces. Population aging is a kind of demographic abnormality that lack of attention causes population problems.

Poisson convergence on the free Poisson algebra

open access: yes, 2015
Based on recent findings by Bourguin and Peccati, we give a fourth moment type condition for an element of a free Poisson chaos of arbitrary order to converge to a free (centered) Poisson distribution.

Nyquist method for Wigner-Poisson quantum plasmas [PDF]

open access: yes, 2002
By means of the Nyquist method, we investigate the linear stability of electrostatic waves in homogeneous equilibria of quantum plasmas described by the Wigner-Poisson system.

Generalized Linear Models in Vehicle Insurance

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014
Actuaries in insurance companies try to find the best model for an estimation of insurance premium. It depends on many risk factors, e.g. the car characteristics and the profile of the driver.

The Complementary Exponentiated Lomax-Poisson Distribution with Applications to Bladder Cancer and Failure Data

open access: yesAustrian Journal of Statistics, 2021
A new continuous four-parameter lifetime distribution is introduced by compounding the distribution of the maximum of a sequence of an independently identically exponentiated Lomax distributed random variables and zero truncated Poisson random variable ...

A new method for obtaining sharp compound Poisson approximation error estimates for sums of locally dependent random variables

open access: yes, 2010
Let $X_1,X_2,...,X_n$ be a sequence of independent or locally dependent random variables taking values in $\mathbb{Z}_+$. In this paper, we derive sharp bounds, via a new probabilistic method, for the total variation distance between the distribution of ...

A Generalization of the Exponential-Poisson Distribution

open access: yes, 2008
The two-parameter distribution known as exponential-Poisson (EP) distribution, which has decreasing failure rate, was introduced by Kus (2007). In this paper we generalize the EP distribution and show that the failure rate of the new distribution can be ...
