A Posteriori Error Estimators for Hierarchical B-Spline Discretizations
(World Scientific, 2018-07)
In this paper we develop function-based a posteriori error estimators for the solution of linear second order elliptic problems considering hierarchical spline spaces for the Galerkin discretization. We obtain a global ...
Local problems on stars: A posteriori error estimators, convergence, and performance
(American Mathematical Society, 2003-07)
A new computable a posteriori error estimator is introduced, which relies on the solution of small discrete problems on stars. It exhibits built-in flux equilibration and is equivalent to the energy error up to data ...
A Posteriori Error Estimates for Lumped Mass Finite Element Method for Linear Parabolic Problems Using Elliptic Reconstruction
(TAYLOR & FRANCIS INC, 2017)
We study residual-based a posteriori error estimates for both the spatially discrete and the fully discrete lumped mass finite element approximation for parabolic problems in a bounded convex polygonal domain in (2). In ...
Interpolation in Jacobi-weighted spaces and its application to a posteriori error estimations of the p-version of the finite element method
(Elsevier Science, 2016-11)
The goal of this work is to introduce a local and a global interpolator in Jacobi-weighted spaces, with optimal order of approximation in the context of the p-version of finite element methods. Then, an a posteriori error ...
A posteriori error estimates for elliptic problems with Dirac measure terms in weighted spaces
(Edp Sciences, 2014-02)
In this article we develop a posteriori error estimates for second order linear elliptic problems with point sources in two- and three-dimensional domains. We prove a global upper bound and a local lower bound for the error ...
A posteriori error estimates for elliptic problems with Dirac measure terms in weighted spaces
(2014)
In this article we develop a posteriori error estimates for second order linear elliptic problems with point sources in two- and three-dimensional domains. We prove a global upper bound and a local lower bound for the error ...
An a posteriori error analysis of a velocity-pseudostress formulation of the generalized Stokes problem
(Journal of Computational and Applied Mathematics, 2020)
Inferência bayesiana para teste disgnóstico.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2004-03-05)
The simpler screening tests applied to detect disease instead of the more elaborated, usually result in the risk of incorrect diagnostic. However, these tests are only useful when the risks of misclassifications are known ...
