Mesh size functions for implicit geometries and PDE-based gradient limiting
Mesh generation and mesh enhancement algorithms often require a mesh size function to specify the desired size of the elements. We present algorithms for automatic generation of a...

Improving Goodput by Relaying in Transmission-Power-Limited Wireless Systems
In wireless communication systems, the capacity of a cell (the amount of correctly delivered traffic in unit time) is a precious resource that can not be arbitrarily increased. T...
