(R2024) A New Weighted Poisson Distribution For Over- and Under-Dispersion Situations

In this paper, we propose a four-parameter weighted Poisson distribution that includes and generalizes the weighted Poisson distribution proposed by Castillo and Pérez-Casany and the Conway- Maxwell-Poisson distribution, as well as other well-known distributions. It is a distribution that is a member of the exponential family and is an exponential combination formulation between the weighted Poisson distribution proposed by Castillo and Pérez-Casany and the Conway-Maxwell- Poisson distribution. This new distribution with an additional parameter of dispersion is more flexible, and the Fisher dispersion index can be greater than, equal to, or less than one. This last property allows it to model over-dispersed data as well as under-dispersed or equi-dispersed data. Many other properties of the new distribution are studied in this article. The parameters are estimated by two methods: the least squares and the maximum likelihood methods. The properties of the estimators are not studied because they follow directly. Two examples of application to real data, taking into account situations of overdispersion and underdispersion, are examined

ANALYSIS OF A COAXIAL-TYPE MEASUREMENT CELL BY FINITE-ELEMENTS METHOD FOR CHARACTERIZING MAGNETIC ANISOTROPIC MATERIALS: DIRECT PROBLEM

The finite elements method has made proof efficiency and precision in many areas as mechanics, thermal, components physics and more recently in the electromagnetism. Its applications allow the processing of homogeneous, inhomogeneous, isotropic or anisotropic medias for any geometry. Our study, concerns the analysis of a coaxial guide in the presence of a saturated ferrite material, the goal of this study is to deduce the electromagnetic behaviour inside the coaxial guide, by determining physical parameters variations in function of material characteristics. The electromagnetic study; lead us to use a coupled equation system of Helmholtz type, which is difficult to solve analytically. This is why we have developed a method of space discretization called FINITE-ELEMENT METHOD, to solve numerically the problem.The finite elements method has made proof efficiency and precision in many areas as mechanics, thermal, components physics and more recently in the electromagnetism.
