Statistical inference for non-homogeneous Poisson process with competing risks: a repairable systems approach under power-law process
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2019-08-30)
In this thesis, the main objective is to study certain aspects of modeling failure time data of repairable systems under a competing risks framework. We consider two different models and propose more efficient Bayesian ...
Nonhomogeneous Euclidean first-passage percolation and distance learning
(Institute of Mathematical Statistics, 2022-02)
Consider an i.i.d. sample from an unknown density function supported on an unknown manifold embedded in a high dimensional Euclidean space. We tackle the problem of learning a distance between points, able to capture both ...
A Bayesian approach for modeling stochastic deterioration

Nova classe de modelos paramétricos para análise de sistemas reparáveis
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2023-01-13)
The Arithimetic Reduction of Age (ARA) model class from Doyen e Gaudoin (2004) has been
widely used in the analysis of repairable systems, whose repair effect is expressed by an arithmetic
age reduction. However, the ...
Nonparametric estimation and bootstrap confidence intervals for the optimal maintenance time of a repairable system
(Computational Statistics & Data Analysis, 2013)
Consider a repairable system operating under a maintenance strategy that calls for complete preventive repair actions at pre-scheduled times and minimal repair actions whenever a failure occurs. Under minimal repair, the ...
Bayesian inference for power law processes with applications in repairable systems
(2012)
Statistical models for recurrent events are of great interest in repairable systems reliability and maintenance. The adopted model under minimal repair maintenance is frequently a nonhomogeneous Poisson process with the ...
Metodologias para modelagem de cargas de consumidores de baixa tensão considerando a integração de resposta da demanda, geração distribuída e veículos elétricos
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2017-03-03)
Accurate load modeling is a crucial task in distribution systems expansion planning. Traditionally, the load peak, which is viewed as the worst-case scenario, has been used to quantify new investment requirements. However, ...
