Abstract Recent years have seen a massive development of geospatial sensing systems informing the use of space. However, rarely do these sensing systems inform transformation towards urban sustainability. Drawing on four global urban case examples, w

This paper starts from the hypothesis that streetscapes with shorter façade lengths are more pleasant for pedestrians than long and monotonous façades. It analyses four case studies where short façade lengths were implemented by applying different

We use perturbation theory and the relativistic Cowling approximation to numerically compute characteristic oscillation modes of rapidly rotating relativistic stars which consist of a perfect fluid obeying a polytropic equation of state. We present a

Using several approximations, we calculate an estimate of the gravitational radiation emitted when two equal mass black holes coalesce at the end of their binary inspiral. We find that about 1% of the mass energy of the pair will emerge as gravitatio

Computations of the strong field generation of gravitational waves by black hole processes produce waveforms that are dominated by quasinormal (QN) ringing, a damped oscillation characteristic of the black hole. We describe here the mathematical prob

Perturbation techniques can be used as an alternative to supercomputer calculations in calculating gravitational radiation emitted by colliding black holes, provided the process starts with the black holes close to each other. We give a summary of th

Quasinormal modes have played a prominent role in the discussion of perturbations of black holes, and the question arises whether they are as significant as normal modes are for self adjoint systems, such as harmonic oscillators. They can be signific

In der religionssoziologischen Konversionsforschung steht derzeit der Islam im Vordergrund. Das rührt daher, dass muslimische KonvertitInnen im Islamic State-Dschihadismus übervertreten sind. So wird häufig argumentiert, dass KonvertitInnen mehr a
