Advanced peptide-based nanomaterials composed of self-assembling peptides (SAPs) are of emerging interest in pharmaceutical and biomedical applications. The introduction of fluorine into peptides, in fact, offers unique opportunities to tune their biophysical properties and intermolecular interactions. In particular, the degree of fluorination play...
Gas turbine engines play a key role in current and future energy markets due to their high load and fuel flexibility, but efficiency gains for these systems are incremental. Pressure gain combustion, through the use of rotating detonation combustors (RDC), promises to bring about a step change in thermodynamic efficiency for propulsion and power ge...
Music-related decision-making encompasses a wide range of behaviours including those associated with listening choices, composition and performance, and decisions involving music education and therapy. Although research programmes in psychology and economics have contributed to an improved understanding of music-related behaviour, historically, the...
Tropical Arenosols may be challenging for agricultural use, particularly in semi-arid regions. The aim of this study was to evaluate the impact of the addition of increasing shares of biochar and clay on the nutrient sorption capacity of a tropical Arenosol. In batch equilibrium experiments, the sorption of ammonium-N (NH+4-N), nitrate-N (NO−3-N), ...
The fight against climate change makes extreme but inevitable changes in the energy sector necessary. These in turn lead to novel and complex challenges for the transmission system operators (TSOs) of gas transport networks. In this thesis, we consider four different planning problems emerging from real-world operations and present mathematical pro...
In the face of ubiquitous surveillance and people’s loss of control over their personal data, informational privacy is widely perceived as irretrievably “dead”. Illustrating the complexity of the problem and contributing to the search for realistic solutions, this cumulative dissertation deals with privacy threats posed by mobile apps, web tracking...
Die Herstellung von variantenreichen Produkten durch hochautomatisierte Anlagen stellt zunehmend eine Kernkompetenz in der Automobilindustrie dar. Insbesondere die Schnittstelle zwischen der Produktentwicklung und der Produktion – der Produktionsentwicklung – trägt diesbezüglich eine hohe Verantwortung und muss sich steigenden Herausforderungen ste...
Die Arbeits- und Pflegesituation in der stationären Demenzpflege ist für Pflegekräfte und Menschen mit Demenz unzureichend. Eine Ursache hierfür ist die Arbeitsverdichtung, die aus dem Mangel an Pflegekräften und der steigenden Zahl pflegebedürftiger Menschen mit Demenz resultiert. Sie führt zu einer erhöhten psychischen und physischen Belastung de...
We consider best approximation problems in a nonlinear subset ℳ of a Banach space of functions (𝒱,∥•∥). The norm is assumed to be a generalization of the L 2-norm for which only a weighted Monte Carlo estimate ∥•∥n can be computed. The objective is to obtain an approximation v ∈ ℳ of an unknown function u ∈ 𝒱 by minimizing the empirical norm ∥u − v...
Aims. The VLBI Global Observing System (VGOS), which is the next generation of geodetic very long baseline interferometry (VLBI), observes simultaneously in four frequency bands in the range 3.0-10.7 GHz (expected to be extended to 14 GHz). Because source structure changes with frequency, we aim to study the source position estimates from the obser...
