Over the past two decades, some very efficient techniques for the numerical solution of partial differential equations have been developed. We are especially interested in adaptive local grid refinement on unstructured meshes, multigrid solvers and parallelization techniques. Up to now, these innovative techniques have been implemented mostly in university… (More)
In the present paper we describe and classify these numerous variants such as BPX, hierachical basis, HBMG, local multi-grid etc. in the framework of multi-grid. We compare additive and multiplicative multi-grid and particularly investigate the different behaviour with respect to smoothing. Theoretical as well as numerical results are presented.
Ground penetrating radar (GPR) typically operates in an electromagnetic near field situation. The electromagnetic fields in this region are in general not plane TEM waves. We investigate an electromagnetic full-wave modeling approach in the time-domain for the analysis of GPR signals.
Fluorescence techniques are widely used as sensitive detection methods in bio-analytics. The use of the bio-physical parameter fluorescence lifetime additional to the spectral characteristics of fluorescence has the potential to improve fluorescence-related detection methods in terms of selectivity in signal recognition, robustness against disturbing… (More)
