Somas aleatórias Poisson misturadas e modelos normais misturados associados
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE ESTATÍSTICAPrograma de Pós-Graduação em EstatísticaUFMG, 2020-02-18)
The sum of a random number of random variables, besides being interesting from a probabilistic point of view, appears in applications involving processes that evolve over time. An important and widely studied example is ...
Integrability vs supersymmetry: Poisson structures of the pohlmeyer reduction
(Springer, 2011-11-01)
We construct recursively an infinite number of Poisson structures for the supersymmetric integrable hierarchy governing the Pohlmeyer reduction of superstring sigma models on the target spaces AdS(n) x S(n), n = 2, 3, 5. ...

Scaling limit of subcritical contact process
(Elsevier Science, 2017-08)
In this paper we study the subcritical contact process on Zd for large times, starting with all sites infected. The configuration is described in terms of the macroscopic locations of infected regions in space and the ...
Algoritmos para a redução de ruído Poisson e estimativa de parâmetros utilizando distâncias estocásticas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCCCâmpus São Carlos, 2018-06-14)
Noise is present in all applications of digital imaging. Due to its stochastic nature, it is impossible to determine exact procedures to completely remove noise from the image. Thus, the target signal may be affected during ...
Filtragem de sinograma tomográfico afetado por ruído Poisson utilizando wavelets anisotrópicas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCCCâmpus São Carlos, 2017-02-07)
The diagnostic imaging by computed tomography has become popular in recent decades. As the image acquisition method is effected by exposing the human body to X-ray dose (ionizing radiation), the frequent realization of ...
The histogram Poisson, lab ele d multi-Bernoulli multi-target tracking filter
(Elsevier, 2020)
A Random Finite Set (RFS) based multi-target filter is proposed, which utilizes a labeled Multi-Bernoulli distribution to model the multi-target state, together with a Poisson RFS distribution to model target birth. Referred ...
Lotka's law: Application of the Langrarian Poisson distribution model to author's productivityLa Ley de Lotka: aplicaciones del modelo Lagrangian Poisson a la productividad de autores

Greedy clearing of persistent Poissonian dust
(Elsevier Science, 2014-10)
Given a Poisson point process on R, assign either one or two marks to each point of this process, independently of the others. We study the motion of a particle that jumps deterministically from its current location to the ...
