Coordinated Projects

This thesis aims to analyze techniques for improving the fault detection capabilities of large cyber-physical systems. The Low-Level Radio Frequency (LLRF) control system of the European X-ray Free Electron Laser (XFEL) is the main target system. [...]

Das Hands-on Lab diente neben der Vorstellung des Projekts auch dem gemeinsamen Informations- und Ideenaustausch mit der Community. In fünf Kleingruppen bearbeiteten die Anwesenden folgende Fragestellungen und Themen [...]

We present an approach for solving optimal boundary control problems of nonlinear optics by using deep learning. For computing high resolution approximations of the solution to the nonlinear wave model, we propose higher order space-time finite element methods in combination with collocation techniques. [...]

A Metropolis-Hastings step is widely used for gradient-based Markov chain Monte Carlo methods in uncertainty quantification. By calculating acceptance probabilities on batches, a stochastic Metropolis-Hastings step saves computational costs, but reduces the effective sample size. [...]

Bei der Erfassung von Publikationen richtet sich der Blick bislang auf bibliographische, technische und organisatorische Metadaten. Diese werden von gängigen Datenbanken weitestgehend erfasst und zum Austausch stehen standardisierte Austauschformate zur Verfügung.Durch den Prozess der Open-Access-Transformation stellt sich zusätzlich die Frage, wie Kosten zukünftig sich auf Forschungseinrichtungen verteilen. [...]

Complex particle reconstruction software used by High Energy Physics experiments already pushes the edges of computing resources with demanding requirements for speed and memory throughput, but the future experiments pose an even greater challenge. Although many supercomputers have already reached petascale capacities using many-core architectures and accelerators, numerous scientific applications still need to be adapted to make use of these new resources. [...]

In the future HEP experiments, there will be a significant increase in computing power required for track reconstruction due to the large data size. As track reconstruction is inherently parallelizable, heterogeneous computing with GPU hardware is expected to outperform the conventional CPUs. [...]

Embedded digital devices, such as Field-Programmable Gate Arrays (FPGAs) and Systems on Chip (SoCs), are increasingly used in dependable or safety-critical systems. These commodity devices are subject to notable hardware ageing, which makes failures likely when used for an extended time. [...]
