BabuDB is an embedded non-relational database system suitable for storing large numbers of arbitrary key-value pairs. It is capable of accomodating databases that exceed...
Short waiting and journey times are the most important features of an elevator group control with high quality of service. Classical systems use landing calls and car...
Within urban development areas domestic and trade wastewater as well as extensive quantities of rainwater dependent on the percentage of impermeability accrue. Since the...
The overall objective of the XtreemOS project is the design, implementation, evaluation and distribution of an open source Grid operating system (named XtreemOS) with...
Symmetries arise naturally in integer programs. Often, there is no reason to distinguish certain objects among others. For instance, the actual number that a certain bus...
The aim of GridChem is to bring computational chemistry onto the Grid, and to contribute to the establishment of (de facto) standards in chemistry-related Grid computing...
In this project we developed a novel theory of path connectivity that generalizes the Steiner tree problem to a hypergraph setting. Main results include a Menger...
Chip Design Verification with Constraint Integer Programming
In the design process of integrated circuits and other electronic hardware, a huge amount of time and resources is spent on the verification of the design and the final...
Digital Neuroanatomy, Data Visualization, and Modelling
This project continues the research started in Virtual NeuroLab.
In this project we will establish a standardized pipeline for the creation of surface-based brain atlases...
Recent progress in basic research has lead to visions how to use new self-organizing networks for advanced information systems. These networks function without central...
The cost sharing problem is a kind of game, in which the costs of an common infrastructure among different members of an organization or a cooperation is partitioned. The...
The structure of fixed telecommunication networks currently undergoes significant changes. More and more applications/services (e-mail, video, fixed and mobile phone...
ENT-Surgery under Consideration of Optimal Nasal Air Flow
Our objective is to analyze and understand the physiology and patho-physiology of normal nasal breathing. To this end, airflow simulations based on computational fluid...
In telecommunication systems different processes consisting of requests have to be served. Various scheduling disciplines are applied for overload control, prioritizing...
The BMBF-project Eibone focused on the investigation and development of fundamentals for an efficient, robust and reliable communication network, which should satisfy the...
Community grid computing aims to provide researchers in a scientific field (i.e. climate research) with an integrated environment for efficient, and secure collaborative...
Cycle and Path Polytopes with and without Length Restrictions
Cycle or path polytopes are the convex hulls of the incidence vectors of (directed) cycles or paths in graphs (digraphs), respectively. By admitting not all cardinalities...
Laser welding has grown up to a key technology in modern car body manufacturing during the last 10 years. In one welding phase, a number of welding robots (usually 2-6)...
For pre-operative planning of interventions in dental implantology as well as maxillofacial surgery an accurate geometric reconstruction of the relevant anatomical...
Discrete Morse theory was developed by Forman as a combinatorial analog to the classical smooth Morse theory. There are numerous applications to questions in...
