Innovation in times of crisis has experienced a flood of research in the wake of recent events. These studies are dispersed over a broad range of fields and do not adequately reflect earlier research or prior crises. To encourage the convergence of related literature streams,&...

Collision avoidance is a topic of growing importance for any satellite orbiting Earth. Especially those satellites without thrusting capabilities face the problem of not being able to perform impulsive collision avoidance manoeuvres. For satellites in low Earth orbits, though, perturbing accelera...

Existing model validation studies in geoscience often disregard or partly account for uncertainties in observations, model choices, and input parameters. In this work, we develop a statistical framework that incorporates a probabilistic modeling technique using a fully Bayesian approach to perfor...

AbstractBeta-glucans are polysaccharides that can be used for different applications, for example as an immunomodulator in food or feed or for managing high cholesterol levels. Certain microalgae species use beta-glucans as energy storage, accumulating them during nutrient depletion. In this stud...

Let q be a prime power and F4(q)be the Chevalley group of type F4over a finite field with q elements. Marcelo and Shinoda (Tokyo J Math 18:303-340, 1995) determined the values of the unipotent characters of F4(q)on all unipotent elements, extending earlier work by Kawanaka...

The adoption of machine learning (ML) in organizations is characterized by the use of multiple ML software components. When building ML systems out of these software components, citizen data scientists face practical requirements which go beyond the known challenges of ML, e. g.,  data&...

This thesis analyzes the behavior of supersecondary structures in the context of embeddings. For this purpose, data from the Protein Topology Graph Library was provided with embeddings. This resulted in a structured graph database, which will be used for future work and analyses. I...

Das rasante Wachstum der E-Mobilität hat zu einem deutlichen Anstieg der Zulassungen von Elektrofahrzeugen (EV) und dem Einsatz von Stromversorgungsanlagen (EVSE) in Deutschland geführt. Entscheidend für den zukünftigen Erfolg der E-Mobilität ist die standardisierte Kommunikation zwischen EV und EVSE, ...

Plasma turbulence, and edge density fluctuations in particular, can under certain conditions broaden the cross-section of injected microwave beams significantly. This can be a severe problem for applications relying on well-localized deposition of the microwave power, like the control of MHD ...

One-dimensional maps with discontinuities are known to exhibit bifurcations somewhat different to those of continuous maps. Freed from the constraints of continuity, and hence from the balance of stability that is maintained through fold, flip, and other standard bifurcations, the attractors ...

We report on photodetection in deep subwavelength Ge(Sn) nano-islands on Si nano-pillar substrates, in which self-aligned nano-antennas in the Al contact metal are used to enhance light absorption by means of local surface plasmon resonances. The impact of parameters such as substrate d...

The screw dislocation mobility in bcc Nb has been studied by molecular dynamics (MD) simulations at different strain rates and temperatures using an embedded-atom method (EAM) potential. Static properties of the screw dislocation, as determined with the EAM potential, are in agreement w...

In the present work, a standard large eddy simulation is combined with tracer particle seeding simulations to investigate the different PIV bias errors introduced by intermittent particle seeding and particle lag. The intermittency effect is caused by evaluating the velocity from tracer ...

Heutzutage finden Laserentfernungsmesser in einer Vielzahl an militärischen, wissenschaftlichen und zivilen Anwendungen Einsatz. Diese werden in alltäglichen Anwendungen, wie etwa beim Sport im Bereich des Golfen und Schießsports um die Entfernung zu bestimmen, welche hierbei für die sportliche Leistung&#x...

This thesis explores the transformative role of machine learning, especially deep learning (DL), in engineering simulations, using material science as a key application area. By transitioning from human-driven to computer-analyzed simulations, DL can accelerate simulation workflows and enhance data in...

Stereotypical assumptions associating high levels of giftedness and outstanding performance with maladaptive behavioral characteristics and personality traits (cf. disharmony stereotype) are rather prevalent in the school context as well as in the musical domain. Such preconceptions among teachers can ...

Der Einsatz von Cloud-Computing bietet Unternehmen durch die Virtualisierung von Rechenressourcen in Verbindung mit dem Zugriff über das Internet eine Vielzahl neuer Möglichkeiten. Innovative digitale Dienstleistungen können in Form von Cloud-Services genutzt und angeboten werden. Infolge wurden die Entwic...

In this paper, we introduce voltage-controlled oscillators (VCOs) as a new type of nuclear magnetic resonance (NMR) detector, enabling dead time-free detection of NMR signals after an excitation pulse as well as the real-time inductive detection of Rabi oscillations during the pulse. To...
