Mesh Movement Governed by Entropy Production
The aim of this paper is to study the feasibility of using (irreversible) entropy production as driving force for a moving mesh. Such a method should be able to capture or track p...

Consistent Approximations and Approximate Functions and Gradients in Optimal Control
As shown in [7], optimal control problems with either ODE or PDE dynamics can be solved efficiently using a setting of consistent approximations obtained by numerical discretizati...

On Acoustic Cloaking Devices by Transformation Media and Their Simulation
By transformation optics, we construct and investigate three-dimensional acoustic cloaking devices for which the device itself and the cloaked region can be mapped into two nested ...

A General Method for Estimating Correlated Aggregates over a Data Stream
—On a stream of two dimensional data items (x, y) where x is an item identifier, and y is a numerical attribute, a correlated aggregate query requires us to first apply a selec...
