Nonconforming Mixed Discretization of Second Orderelliptic

Nonautonomous Discrete Dynamics: Discretization and Taylor Approximation

In this talk, we consider a class of nonautonomous difference equations (recursions) possessing an attractive invariant manifold in the extended state space. It is our aim to study the behavior of this manifold, as well as of its corresponding asymptotic phase under perturbation. Our framework is sufficiently general to include discrete counterparts of (center-)unstable and inertial manifolds. ...

Nonconforming Mixed Discretization of Second Order Elliptic Problems

In the realm of nite element discretizations of elliptic problems a basic distinction can be made between conforming and nonconforming methods. The latter rely on approximations not contained in the space the exact solution lives in. Since additional diiculties are thus introduced nonconforming approaches usually are a last resort: if satisfactory conforming spaces prove elusive they are given ...

Further modified Taylor retractor for spinal surgery.

New techniques have minimized the incision length and thus required modifications of surgical instruments. The Taylor retractor is one of these instruments. We therefore designed several modifications of the classical Taylor retractor. The following structural modifications were made on the classical Taylor retractor: First, we provided detachable blades with three different lengths (60, 70, 80...

A Modified Chi2 Algorithm for Discretization

ÐSince the ChiMerge algorithm was first proposed by Kerber in 1992, it has become a widely used and discussed discretization method. The Chi2 algorithm is a modification to the ChiMerge method. It automates the discretization process by introducing an inconsistency rate as the stopping criterion and it automatically selects the significance value. In addition, it adds a finer phase aimed at fea...
