A residual based A POSTERIORI error estimator for an augmented mixed finite element method in linear elasticity [PDF]
In this paper we develop a residual based a posteriori error analysis for an augmented mixed finite element method applied to the problem of linear elasticity in the plane. More precisely, we derive a reliable and efficient a posteriori error estimator

Maximum norm a posteriori error estimate for a 2d singularly perturbed semilinear reaction-diffusion problem [PDF]
A singularly perturbed semilinear reaction-diffusion equation, posed in the unit square, is discretized on arbitrary nonuniform tensor-product meshes. We establish a second-order maximum norm a posteriori error estimate that holds true uniformly in the ...

Maximum norm a posteriori error estimation for parabolic problems using elliptic reconstructions [PDF]
A semilinear second-order parabolic equation is considered in a regular and a singularly perturbed regime. For this equation, we give computable a posteriori error estimates in the maximum norm.

A posteriori corrections for cubic and quintic interpolating splines at equally-spaced knots [PDF]
The method proposed recently by Lucas [13], for the a posteriori correction of odd degree interpolating periodic splines is extended to non-periodic cubic and quintic ...

Saturation Assumption and Finite Element Method for a One-Dimensional Model [PDF]
In this paper we refer to the hierarchical finite element method and stabilization techniques for convection–diffusion equations. In particular, the aim is to outline an application of saturation assumption to a posteriori error estimates for such ...

A Priori or a Posteriori? [PDF]
What is the significance of the distinction between the a priori and the a posteriori in metametaphysics? The primary relevance of the distinction concerns the source of metaphysical knowledge and our epistemic access to that source. For instance, how can we gain knowledge about things like numbers and sets, which are abstract objects?

In this paper, we develop an a posteriori error analysis for the stationary Stokes-Darcy coupled problem approximated by conforming the finite element method on isotropic meshes in ℝd, d∈2,3.

Residual based a posteriori error estimation for Dirichlet boundary control problems [PDF]
We study a residual–based a posteriori error estimate for the solution of Dirichlet boundary control problem governed by a convection diffusion equation on a two dimensional convex polygonal domain, using the local discontinuous Galerkin (LDG) method ...

Universal a posteriori metrics game [PDF]
Over binary input channels, uniform distribution is a universal prior, in the sense that it allows to maximize the worst case mutual information over all binary input channels, ensuring at least 94.2% of the capacity. In this paper, we address a similar question, but with respect to a universal generalized linear decoder.
