Intraoperative Gamma Cameras are becoming increasingly common for radio-guided surgery. Coded Aperture Imaging has been proposed as a collimation technique, because it offers a better trade-off between sensitivity and spatial resolution, but requires image reconstruction. Therefore, a Convolutional Encoder-Decoder Network was developed and quantitatively compared with analytical methods. Furthermore, 3D-localization of point-like sources was investigated.

The focus of this work is on human driving behavior in road traffic. Two aspects of it are covered, the prediction of it, including the identification of relevant influencing factors, as well as the behavior generation for autonomous vehicles.
The behavior prediction is based on a field study during which participants drove a measurement vehicle through inner-city traffic. Using the driven trajectories and lidar recordings complexity features to describe the surroundings at the intersection, the traffic there and the driving path are defined. The driving behavior is characterized by further features. Based on the complexity features regression models are trained to predict the behavior features. For that, linear regression, random forest and gradient boosting machine are utilized. Different complexity feature sets, including ones that are reduced with the help of an autoencoder, are used for prediction. The results show that the driving behavior can be predicted reliably. However, when using complexity feature sets with only few features the prediction performance is reduced.
In order to obtain a complexity score that is in line with human perception of complexity, an online study using videos of approaches to intersections was conducted. In pairwise comparisons participants were asked to identify the more complex situation. From that data complexity scores for the intersection passes included in the study are calculated. Several methods are used to assign these scores to the runs of the original field study. Behavior regression models are trained using these assigned complexity scores. The results show that behavior prediction with the complexity scores is possible, however, most variants require to also consider the turning direction as a second feature.
The behavior generation for decision-making at T-intersections is based on a discrete event system (DES). For it, several features are used to define events that describe the status of the decision-making process at the intersection. The events trigger the transitions between the states of the DES. All states are associated with either offensive or defensive driving behavior, which is implemented using the intelligent driver model. The algorithm is validated with a simulation framework. Using a generic map and several real maps, the decision-making model is simulated 14400 times while interacting with further cooperation vehicles. None of these runs resulted in a collision involving the vehicle running the algorithm and the times to pass the intersection can be explained by the numbers of cooperation vehicles and the intersection layouts. Further simulations are used to investigate the influence of limited visibility at the intersections on the model.

Distributed usage control allows to regulate the use of data even after sharing. However, existing solutions are susceptible to manipulation by dishonest data receivers. This work investigates the use of trusted computing to achieve a trustworthy usage control enforcement process. For this, a suitable system architecture and several remote attestation protocols are designed and implemented. The resulting usage control framework is evaluated using a smart manufacturing application scenario.

Angesichts der Energiewende in Deutschland, stehen Netzbetreiber vor der Herausforderung eine zuverlässige Energieübertragung bereitzustellen. Der Einsatz supraleitender Kabel stellt hierbei eine Alternative für konventionelle Mittel- und Hochspannungstechnik dar. Daher werden in dieser Arbeit unterschiedliche hochtemperatursupraleitende Mehrleiterkonzepte für ein dreiphasiges Mittelspannungskabel untersucht. Ziel ist ein kompaktes Kabeldesign bei geringen elektrischen Verlusten.
Given the energy transistion in Germany, network operators face the challenge of providing reliable energy transmission. The use of superconducting cables represents an alternative for conventional medium- and high-voltage technology. Therefore, this work investigates various high-temperature superconducting multi-conductor concepts for a three-phase medium-voltage cable, aiming to achieve a compact cable design with low electrical losses.

This work proposes a passivity-based framework for the decentralized stabilization of networked energy systems. Its key innovation are equilibrium-independent, passivity-based conditions for modularly inferring asymptotic stability. The framework allows for topology-independent, flexible system configurations in a plug-and-play fashion and extends to other control solutions and technologies, enabling holistic system and control approaches for networked multi-energy systems.
