For 2863 - Ultrawideband Sampling
The metrology of wireless communication has to properly represent the complex interaction of the digital and analog signal domains. The high bandwidth at THz frequencies allows for extreme radio frequency (RF) bandwidth and hence also very large baseband bandwidth. In the baseband the broadband analog signals are digitized by broadband ...

FOR 2863 - Active THz Transceiver Components
Compared to radios operating at purely optical wavelengths or RF/microwave frequencies, the combination of extremely high absolute bandwidths and high relative bandwidths in the THz frequency regime, paired with the severe performance limitations of technologies operating in the so-called "THz-gap", imposes unique challenges on modern digital ...

Der Kampf um die Reichsabtei Corvey im Drei?igj?hrigen Krieg – Akteure, Strategien und Allianzen (Arbeitstitel)
Das Thema ?Corvey im Drei?igj?hrigen Krieg“ hat in der bisherigen wissenschaftlichen Auseinandersetzung mit der Klostergeschichte Corveys wenig Beachtung erfahren. Dieser Umstand ist erstaunlich, werden doch diese Jahrzehnte in der Literatur h?ufig als ?Tiefpunkt“ der Abteigeschichte beschrieben, welche bereits ab der Zeit des Sp?tmittelalters als ...

Electron dynamics at surface-modified photocathodes
This project aims to understand the fundamental processes that govern electron dynamics and energetics of prototypical photoelectrode surfaces, the associated internal interfaces near semiconductor surfaces and related model systems in view of photoelectrochemical hydrogen generation. The detailed mechanisms of interfacial electron transfer ...

CRC 901 - Practicable Cryptographic Techniques for Secure and Data-efficient Customer Loyalty Systems (Transfer project T2)
In subproject a new customer loyalty system for the retail sector will be developed and evaluated. Compared to existing systems, which are expensive and expensive, lack transparency and require trust in the operator, the new system will set new standards in terms of security, privacy, and economic efficiency. To achieve this goal the cryptographic ...

Super-Brownian Motion with single point source: Regularization, approximation and path properties
So called Hamiltonians with point interactions have intensively and successfully been studied for a rather long time mainly form the perspective of mathematical physics as a model of a quantum mechanical system having an extremly short range interaction. A very thorough survey about major results and properties concerning point interactions can be ...

Looking at Patterns - Exploring pattern-recognition of primary school children with eye tracking
This project examines the potential of using eye tracking to investigate pattern-recognition processes of children with mathematical talents and children with difficulties in learning mathematics at the end of primary school. The initial focus is on the question how processes of pattern-recognition processes can be reconstructed from eye tracking ...

t.evo – Die Evolution von komplexen Textmustern: Entwicklung und Anwendung eines korpuslinguistischen Analyseverfahrens zur Erfassung der Mehrdimensionalit?t des Textmusterwandels
Ziel des Projekts t.evo war die Ermittlung geeigneter Indikatoren für historischen Textmusterwandel anhand einschl?giger Textsorten der Gebrauchsliteratur der jüngeren Sprachgeschichte (Presse- und Erbauungsschrifttum). Trotz der sprachhistorischen Bedeutung der betrachteten Textsorten erfolgten Untersuchungen zu deren Textmusterwandel bislang nur ...
