An <i>a posteriori</i> error indicator for discontinuous Galerkin approximations of fourth-order elliptic problems

Emmanuil H. Georgoulis, Paul Houston and Juha Virtanen.

in IMA Journal of Numerical Analysis

January 2011; p ublished online September 2009 .

Journal Article. Subjects: Mathematics. 0 words.

We introduce a residual-based a posteriori error indicator for discontinuous Galerkin discretizations of the biharmonic equation with essential boundary conditions. We show that the...

An a posteriori error indicator for discontinuous Galerkin discretizations of <i>H</i>(curl)-elliptic partial differential equations

Paul Houston, Ilaria Perugia and Dominik Schötzau.

in IMA Journal of Numerical Analysis

January 2007; p ublished online January 2007 .

Journal Article. Subjects: Mathematics. 0 words.

We introduce a residual-based a posteriori error indicator for discontinuous Galerkin discretizations of H(curl; Ω)-elliptic boundary value problems that arise in eddy current models. We...

A 'taut string algorithm' for straightening a piecewise linear path in two dimensions

MJD Powell.

in IMA Journal of Numerical Analysis

January 1998; p ublished online January 1998 .

Journal Article. Subjects: Mathematics. 0 words.

A piecewise linear path in two dimensions is formed by drawing straight lines between adjacent points in the sequence {ui :i=1,2,...,n}. Let Δ be a given positive number such...

The Aalen additive gamma frailty hazards model

Torben Martinussen, Thomas H. Scheike and David M. Zucker.

in Biometrika

December 2011; p ublished online October 2011 .

Journal Article. Subjects: Probability and Statistics. 0 words.

In this paper, we consider clustered right-censored time-to-event data. Such data can be analysed either using a marginal model if one is interested in population effects or using so-called...

Aalen Additive Hazards Change-Point Model

Torben Martinussen and Thomas H. Scheike.

in Biometrika

December 2007; p ublished online August 2007 .

Journal Article. Subjects: Probability and Statistics. 0 words.

We study a test comparing the full Aalen additive hazards model and the change-point model, and suggest how to estimate the parameters of the change-point model. We also study a test for no...
