Let F be a local or global field and let G be a linear algebraic group over F. We study Tannakian categories of representations of the Kottwitz gerbes Rep(Kt_F) and the functor G → B(F,G) defined by Kottwitz in [28]. In ...

The seamless connection of control devices, physical assets, and IT systems through internet-based networks is one of the current megatrends. Especially the manufacturing industry experiences disruptive changes in how ...

Interferometry is the ultimate technology for overcoming the limitations which diffraction and the atmosphere-induced seeing impose on the resolution achievable with ground-based telescopes. The latest generation of ...

In der vorliegenden Arbeit wird eine neue Methodenkombination aus dynamischer Festphasenextraktion (Headspace solid-phase dynamic extraction, HS-SPDE), Gaschromatographie (GC) und Massenspektrometrie (MS) oder Tandem-Mas ...

Ziel dieser Arbeit war es, die Kenntnisse über die Reaktivität modifizierter einkristalliner Platinoberflächen zu vertiefen und mögliche Strategien zur gezielten Modifizierung solcher geordneten, periodisch gestuften ...

This dissertation focuses on the challenges and methods in analyzing multivariate time series (MVTS) data, crucial in various fields like finance, healthcare, and sports. The raw MVTS data, often complex due to its volume ...

A certain two-phase model is considered, which stands some relation with a description of the vortex sheet configuration in a perfect fluid.
Both a sharp and a relaxed version of the evolution can be understood as ...

Dark matter studies in elliptical galaxies were long hampered by the lack of suitable dynamical tracers. The advent of 8 m-class telescopes equipped with multi-object spectrographs has made it possible to use globular ...

The thesis set out to investigate the nature and genesis of the peculiar class of X-shaped radio galaxies. X-shaped sources are puzzling because of the extremely low number of objects of that type. Three scenarios were ...
