Die Wurzeln des militärische Luftbildwesens reichen bis in die Zeit vor dem Ersten Weltkrieg zurück. Die Entwicklungslinien in den deutschen Staaten bis 1945 nachzuverfolgen, ist Gegenstand dieses Buches. Im Mittelpunkt stehen Frage nach dem Zusammenwirken von Militär und dieser Technologie. Diese Veröffentlichung hat propädeutischen Charakter, indem sie diese Grundlagen für die deutschen Luftaufnahmen erläutert und auf Zugangs- und Verwendungsmöglichkeiten hinweist. An overview on the history of military aerial photography in the German military from the beginning to the end of World War II.

Thema dieser Arbeit ist die Bildung von Revieren, d.h. die Aufteilung von homogenen Kunden auf die Anbieter in einem experimentellen Oligopol-Kontraktmarkt. Es wird ein Revierindikator auf Basis der Kaufhistorie und fehlender Anbietergebote definiert. Untersucht wird, inwiefern Revierbildung durch die Zeit, fehlende Kommunikationsmöglichkeit oder fehlende Angebotstransparenz beeinflusst wird sowie die Wirkung von Revieren auf die Transaktionspreise. This work focusses on the establishment of territories, i.e. the allocation of homogeneous customers among the suppliers in an experimental oligopoly contract market. A territory indicator is defined based on the purchase history and missing supplier offers. It is examined to what extent the establishment of territories is influenced by time, lack of communication or lack of offer transparency as well as the effect of territories on transaction prices.

The presented work provides an approach and an implementation for enabling decentralized control in distributed applications composed of heterogeneous components by benefiting from the interoperability provided by the Web stack and relying on semantic technologies for enabling data integration. In particular, the concept of Smart Components enables adaptability at runtime through an adaptation layer and is complemented by a reference architecture as well as a prototypical implementation.

This work presents a design methodology for pattern reconfigurable antennas in automotive applications. Channel simulation is used to identify the relevant beam directions prior to the design of the antenna. Based on this knowledge several reconfigurable multiple antenna systems are designed. These antennas are evaluated by the channel capacity calculation from virtual and real-world test drives. An increase of the channel capacity by a factor of 2 compared to a conventional system is observed.

Im Rahmen der Arbeit wird ein Fahrerassistenzsystem für vorausschauendes automatisiertes Fahren entwickelt. Es umfasst die Längs- und Querführung des Fahrzeugs sowie die Steuerung der relevanten Triebstrangkomponenten. Dabei werden Vorausschauinformationen über die Fahrzeugumgebung ausgewertet, um ein energie- und komfortoptimales Fahrverhalten zu erreichen. The work covers the development of a driver assistance system for anticipatory automated driving that controls lateral and longitudinal vehicle motion as well as relevant drivetrain components. It evaluates predictive information about the vehicle's environment to enable energy-efficient and comfortable driving.

Perovskite solar cells are the new hope of next-generation photovoltaic concepts for sustainable energy generation. Regarding their favorable optoelectronic properties, bound electron-hole pairs (so-called excitons) play a significant role and are thoroughly investigated utilizing various spectroscopic methods. Moreover, bandgap instabilities caused by segregation effects in mixed perovskites are analyzed in detail using electroreflectance spectroscopy and structural characterization techniques.

This work addresses recycling effects on carbon fibres and their composites. Developments in single fibre testing, such as the consideration of non-circular fibre shapes and direct strain measurements, are presented. The bulk moulding compound process appears to be a straightforward recycling route for end-of-life fibres and production waste. The investigations shall encourage industry do substitute virgin material with recycled fibres, supporting their pursuit of sustainable mobility.

Superconducting nanowire single-photon detectors (SNSPDs) are very promising as integrated detectors for future quantum photonic integrated circuits. In this work, main technological challenges for the integration of NbN based SNSPDs onto GaAs based phonic circuits are addressed. A new approach to improve the performance of meander style SNSPDs based on a variable thickness is introduced and the first full integration of a quantum photonic chip on a scalable monolithic platform is demonstrated.

In this work, the dynamic behavior of a lean combustion race engine is investigated with regard to cycle-averaged component temperatures, heat fluxes and piston failure under high cycle fatigue loading. A special focus lies on the influence of various engine settings, like ignition time and the airfuel ratio. For the introduced stationary, as well as transient, temperature calculation method, in cylinder pressure curves are measured and processed statistically by probability density functions.

Diese Arbeit thematisiert die Homogenisierung gleitsystemübergreifender Versetzungsreaktionen in einer physikalisch begründeten Formulierung der Metallplastizität. Basierend auf Vergleichen mit diskreten Versetzungsdynamiksimulationen wird eine Beschreibung von Versetzungsnetzwerken entwickelt. Damit wird die Verfestigung als eine Folge der Evolution von Versetzungsnetzwerken erreicht, welche wiederum aus einem Zusammenspiel aus plastischer Scherung und physikalischen Mechanismen entsteht. This work deals with the homogenization of dislocation reactions across slip systems in a physically based three-dimensional formulation of metal plasticity. Based on comparisons with discrete dislocation dynamics simulations, a description of dislocation networks is developed. Thereby, strain hardening is achieved as a consequence of the evolution of dislocation networks, which in turn results from an interaction of plastic slip and physical mechanisms.
