The empirical relation between density and velocity of pedestrian movement is not completely analyzed, particularly with regard to the ‘microscopic’ causes which determine the relation at medium and high densities. The simplest system for the investigation of this dependency is the normal movement of pedestrians along a line (single-file movement). This(More)
Capacity estimation is an important tool for the design and dimensioning of pedestrian facilities. The literature contains different procedures and specifications which show considerable differences with respect to the estimated flow values. Moreover do new experimental data indicate a stepwise growing of the capacity with the width and thus challenge the(More)
For the proper understanding and modelling of pedestrian dynamics, reliable empirical data is necessary for analysis and verification. This paper discusses laboratory experiments at T-junctions: the setup, the extraction of the trajectories of the pedestrians and the analysis of the resulting data. Such experiments give us the opportunity to selectively(More)
The modeling of large biomolecular assemblies frequently requires a combination of multi-resolution data from a variety of biophysical sources. Several algorithmic solutions to this docking problem have been proposed which are usually based on the spatial cross correlation. In [1] it was shown that Laplace-filtering techniques can improve the docking(More)
We present a system to conduct laboratory experiments with thousands of pedestrians. Each participant is equipped with an individual marker to enable us to perform precise tracking and identification. We propose a novel rotation invariant marker design which guarantees a minimal Hamming distance between all used codes. This increases the robustness of(More)
Traffic research has reached a point where trajectories are available for microscopic analysis. The next step will be trajectories which are connected to human factors, i.e information about the agent. The first step in pedestrian dynamics has been done using video recordings to generate precise trajectories. We go one step further and present two(More)
Since the pioneering work of Greenshields the fundamental diagram is used to characterize and describe the performance of traffic systems [1,2]. During the last years the discussion and growing data base revealed the influence of human factors, traffic types or ways of measurements on this relation, see e.g. [3,4] and many others. The manifoldness of(More)
We describe an immersive visualization system for structural biology using real-time load balancing of virtual reality and haptic rendering. In structural biology a variety of image reconstruction techniques are employed to determine geometric aspects of large macromolecular assemblies at various levels of resolution. Hybrid modeling techniques are the most(More)
