Abstract Cars are dominating urban traffic in cities around the world, even though daily trips many often realized with active modes of transportation or public transport. Urban transport planning processes need to adapt this reality and necessity climate change mitigation. Against background, research project “Mobility Reporting”, a joint undertaking district Pankow Berlin researchers from TU ...

We introduce a new mechanism-design problem called fair imposition. In this setting a center wishes to fairly allocate tasks among a set of agents whose cost structures are known only to them, and thus will not reveal their true costs without appropriate incentives. The center, with the power to impose arbitrary tasks and payments on the agents, has the additional goal that his net payment to t...

In 1965, T. J. Willmore conjectured that the integral of the square of the mean curvature of a torus immersed in R is at least 2π. We prove this conjecture using the min-max theory of minimal surfaces.

We assess the behaviour of 5 different feature extraction methods for an acoustic event classification task—built using the same SVM underlying technology—by means of two different techniques: accuracy and the entropy triangle. The entropy triangle is able to find a classifier instance whose relatively high accuracy stems from an attempt to specialize in some classes to the detriment of the ove...

It is known that Jovian radio and high energy electron emissions are observed near Earth. The question we address in this study whether the quasi-periodic ~10 h ~40/15–20 min (QP-10 h, QP-40/15–20 min) energetic particle magnetic field periodicities by Ulysses during its distant encounter with Jupiter 2003 were also detectable as far Earth’s orbit. Surprisingly, found at end of extreme Hallowee...
