This paper analyses how many euro coins outflow from Germany and which composition of coins is to be expected in the long run. To this end, a simple mathematical model is formulated and calibrated for €1 coins. The introduction of the euro coins in 2002 presented a unique opportunity to...

Das vorliegende Papier beschäftigt sich mit der Frage, wie viele ausländische Euro-Münzen pro Tag in ein Euro-Land einströmen. Dafür formulieren wir ein kleines formalmathematisches Modell, das wir für den Fall Deutschlands und 1-Euro-Münzen kalibrieren. Die Einführung der Euro-Münzen...

The performance of various structure characteristics in the task of indicating structural peculiarities in packings of hard spheres is investigated. Various characteristics based on Voronoi polyhedra, spherical harmonics, and Delaunay simplices are considered together with the pair correlation...

Second-order characteristics are important in the description of various geometrical structures occurring in foams, porous media, complex fluids, and phase separation processes. The classical second order characteristics are pair correlation functions, which are well-known in the context of...
