Power-grid systems constitute one of the most complex man-made spatially extended structures. These operate with strict operational bounds to ensure synchrony across the grid. This is particularly relevant for power-grid frequency, which operates strictly at 50 Hz (60 Hz). Nevertheless, small fluctuations around the mean frequency are present at very short time scales <2 s and can exhibit highly complex spatio-temporal behaviour. Here we apply superstatistical data analysis techniques to…

Statistical characterization of airplane delays
The aviation industry is of great importance for a globally connected economy. Customer satisfaction with airlines and airport performance is considerably influenced by how much flights are delayed.
The master programme in Applied Geology aims to provide comprehensive knowledge based on various branches of Geology, with special focus on Applied geology subjects in the areas of Geomorphology, Structural geology, Hydrogeology, Petroleum Geologists, Mining Geology), Remote Sensing and Environmental geology.
Superstatistical modelling of protein diffusion dynamics in bacteria
A statistical model is developed for the diffusive motion of the proteins within the bacterium, based on a superstatistics with two variables that hierarchically takes into account the joint fluctuations of both the anomalous diffusion exponents and the diffusion constants.
Quasiequilibrium self-gravitating systems
Because of the long-range nature of the gravitational interaction, self-gravitating systems never reach thermal equilibrium in the thermodynamic limit but remain trapped in nonequilibrium stationary
