Degradation modeling for reliability analysis with time-dependent structure based on the inverse gaussian distribution
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2017-04-07)
Conventional reliability analysis techniques are focused on the occurrence of failures over
time. However, in certain situations where the occurrence of failures is tiny or almost null, the
estimation of the quantities ...
Spectral mixture kernels for Multi-Output Gaussian processes
(Universidad de Chile, 2017)
Multi-Output Gaussian Processes (MOGPs) are the multivariate extension of Gaussian processes (GPs \cite{Rasmussen:2006}), a Bayesian nonparametric method for univariate regression. MOGPs address the multi-channel regression ...
A class of mixtures of dependent tail-free processes
(OXFORD UNIV PRESS, 2011)
We propose a class of dependent processes in which density shape is regressed on one or more predictors through conditional tail-free probabilities by using transformed Gaussian processes. A particular linear version of ...
Mixture of changing uniaxial micellar forms in lyotropic biaxial nematics
(TAYLOR & FRANCIS LTD, 2008)
Lyotropic nematics consisting of surfactant-cosurfactant water solutions may present a biaxial phase or direct U(+) <-> U(-) transitions, in different regions of the temperature-relative concentration phase diagram, for ...
Non-Gaussian Stochastic Volatility Model with Jumps via Gibbs Sampler
(Universidade Federal de Minas GeraisUFMG, 2017-02-21)
To understand the behavior of asset prices is essential for capital allocation decisions between the available investment option. Such decision depends on what one thinks about risks and returns associated with these ...
Spectral simulation of vector random fields with stationary gaussian increments in d-dimensional euclidean spaces
(Springer, 2017)
This paper addresses the problem of simulating multivariate random fields with stationary Gaussian increments in a d-dimensional Euclidean space. To this end, one considers a spectral turning-bands algorithm, in which the ...
Energy nonequipartition in a collisional model of a confined quasi-two-dimensional granular mixture
(American Physical Society, 2020)
A collisional model of a confined quasi-two-dimensional granular mixture is considered to analyze homogeneous steady states. The model includes an effective mechanism to transfer the kinetic energy injected by vibration ...
