Benefiting and accessing high-performance computing resources can be quite difficult. Unlike domain scientists with a background in computational science, non-experts coming from, e.g., various medical fields, have almost no chance to run numerical simulations on large-scale systems. [...]

We present technical details of an analysis of pseudo-scalar data from a QCD simulation with staggered fermions. The data were obtained close to the physical point with an inverse lattice spacing of about 3 GeV, and N_f =2+1+1. [...]

In the simulation of pedestrian bottleneck flow with velocity-based models stable clogging could be observed, which is not in line with the movement of pedestrians in the real world. Four velocity-based models with different structures are selected in this paper to explore the cause of the phenomenon by identifying and analysing stable clogging. [...]

We present experiments on the behaviour of participants in front of a bottleneck. The waiting area was limited by a corridor of barriers leading straight to an entrance gate. [...]

This paper compares three methods for smoothing trajectories from controlled experiments to determine the main movement direction: central moving average, spline interpolation of inflection points, and moving convex hull. The often-used method of averaging needs an adaptation due to the velocity but nevertheless is less accurate than the others. [...]

Voronoi diagrams are an established method in the analysis of pedestrian motion for constructing a density from two-dimensional positions. It is in turn used to give pointwise values for speed, movement direction, flow etc. [...]

The distribution of passengers waiting for a train is one of the limiting factors when improving the performance of a train station, as it heavily influences the boarding and alighting times of trains. We introduce a probability-based model for the pedestrians' choice of a waiting position. [...]
