This project is concerned with the visualization and analysis of three-dimensional tensor fields. Due to the complexity of tensor data, visualization methods have to be...
The goal of this project is to generate stochastic anisotropic samples with Poisson-disk characteristic over a two-dimensional domain. In contrast to isotropic samples...
The goal of this project is to develop a method for computing a tensor field segmentation based on the topological structure of the eigenvector-fields and the...
Analysis and comparison of vector fields can be done via a segmentation of the flow field into regions of similar behavior and a subsequent extraction of the topological...
Global online services have millions of customers with thousands of servers located throughout the world. At this scale, components fail continuously and it is difficult...
For large-scale, nonlinear, time-dependent PDE constrained optimization problems with a 3D spatial domain, reduced methods are a viable algorithmic approach. The...
Nowadays, the airlines use discrete optimization in many fields in order to plan and control resources like crews and aircraft. The biggest recent problem is a growing...
Zentrale Eigenschaft des aus zwei Komplexen (ZIB und RRZN/Universität Hannover) bestehenden Gesamtsystems ist die Ein-System-Eigenschaft. Das verteilte Gesamtsystem wird...
The DGI project develops a robust, flexible, and sustainably usable Grid infrastructure in Germany, that will become the basis for new ways of working in science and...
Image-Based Analysis of Pore and Particle Structures
The goal of this project is to develop an analysis environment for high-resolution CT scans of porous materials. This environment will integrate methods to compute the...
Visualization and Feature Extraction for Flow Fields
Flow fields play an important role in science and engineering. We developed various methods for the visual analysis of flow fields. See publications below for details.
Binding of a multivalent ligand to a multivalent receptor consists of kinetically different elemetary steps. The first binding event is an intermolecular process, whereas...
