Maximum a posteriori joint state path and parameter estimation in stochastic differential equations
(Universidade Federal de Minas GeraisUFMG, 2014-08-13)
A wide variety of phenomena of engineering and scientific interest are of a continuous-time nature and can be modeled by stochastic differential equations (SDEs), which represent the evolution of the uncertainty in the ...
Analysis of urban pollution episodes by inverse modeling
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Urban pollution episodes pose two relevant issues: a) was the episode controlled by specific meteorology, a rise of emissions or both? b) Were mitigation measures effective in curbing down pollution? A methodology for ...
A DPG method for linear quadratic optimal control problems
(Elsevier Ltd, 2024)
The DPG method with optimal test functions for solving linear quadratic optimal control problems with control constraints is studied. We prove existence of a unique optimal solution of the nonlinear discrete problem and ...
A-posterirori error estimates for linear exterior problems via mixed-FEM and DtN mappings.
(2002)
In this paper we combine the dual-mixed finite element method with a Dirichlet-to-Neumann mapping (given in terms of a boundary integral operator) to solve linear exterior transmission problems in the plane. As a model we ...

A priori and a posteriori error analyses of a pseudostress-based mixed formulation for linear elasticity
(Computers and Mathematics with Applications vol.71 no.2 585-614 2016, 2016-01-02)
In this paper we present the a priori and a posteriori error analyses of a non-standard mixed finite element method for the linear elasticity problem with non-homogeneous Dirichlet boundary conditions. More precisely, the ...
Uma abordagem bayesiana para modelos de degradação: a obtenção da distribuição preditiva a posteriori dos tempos de falha de unidades amostrais futuras e sob teste: a obtenção da distribuição preditiva a posteriori dos tempos de falha de unidades amostrais futuras e sob teste
(Universidade Federal de Minas GeraisUFMG, 2011-02-21)
Reliability is a branch of Statistical inference which seeks to describe the route failure time distribution of objects of interest. The conventional techniques are geared towards the occurrence of failures over time. ...
