Adaptive control of local errors for elliptic problems using weighted Sobolev norms
(John Wiley & Sons Inc, 2017-07)
We develop an a posteriori error estimator which focuses on the local H1 error on a region of interest. The estimator bounds a weighted Sobolev norm of the error and is efficient up to oscillation terms. The new idea is ...
On a Multiscale a Posteriori Error Estimator for the Stokes and Brinkman Equations
(2015)
This work proposes and analyzes a residual a posteriori error estimator for the Multiscale Hybrid-Mixed (MHM) method for the Stokes and Brinkman equations. The error estimator relies on the multi-level structure of the MHM ...

Error estimates for a neumann problem in highly oscillating thin domains
(2013-01-01)
In this work we analyze the convergence of solutions of the Poisson equation with Neumann boundary conditions in a two-dimensional thin domain with highly oscillatory behavior. We consider the case where the height of the ...

Application of Affine Estimators to Single Tone Frequency Estimation
(Sociedad Argentina de Informática, 2012)
Affine estimation has emerged as a promising technique toreduce the mean squared error (MSE) between the estimated parametersand the true value of these parameters. The aim of this paper is to obtainan affine estimator for ...
