This thesis studies the development of LEKID arrays for the use in a mm-wave camera for the IRAM 30m telescope. This includes the design and fabrication of the superconducting microresonators, the modeling and optimization ...
Development of Microactuators Based on the Magnetic Shape Memory Effect
(2013)
The giant magneto-strain effect in Ni-Mn-Ga alloys is particularly attractive for actuator applications. Two different approaches are being pursued to develop MSM microactuators. To observe large deflections of Ni-Mn-Ga ...
Development of a completely decentralized control system for modular continuous conveyors
(2009)
To increase the flexibility of continuous conveyor systems, a completely decentralized control system for a modular conveyor system was developed. The system is able to carry conveyor units without any centralized ...
Development of an Air Coil Superconducting Fault Current Limiter
(2016)
Electrical power grids are the lifeline of technical infrastructure and fundamental for industry and modern lives. Fault Currents can disrupt the continuous supply of electrical energy, cause instable grid conditions and ...

Dynamic Network Notation: A Graphical Modeling Language to Support the Visualization and Management of Network Effects in Service Platforms
(2013)
Service platforms have moved into the center of interest in both academic research and the IT industry due to their economic and technical impact. These multitenant platforms provide own or third party software as metered, ...
Dynamic risk management with Markov decision processes
(2008)
An important tool in risk management is the implementation of risk measures. We study dynamic models where risk measures and dynamic risk measures can be applied. In particular, we solve various portfolio optimization ...
Dynamic Capacity Control in Air Cargo Revenue Management
(2013)
This book studies air cargo capacity control problems. The focus is on analyzing decision models with intuitive optimal decisions as well as on developing efficient heuristics and bounds. Three different models are studied: ...
Elastomerreibung und Kraftübertragung beim Abscheren von aktiv betriebenen Vakuumgreifern auf rauen Oberflächen
(2017)
The present work includes the analysis of the load transmission and the modeling of the friction coefficient ? on rough surfaces during the shearing process of actively-driven vacuum grippers. The two main components of ...
Elastic and Inelastic Scanning Tunneling Spectroscopy on Iron-Based Superconductors
(2019)
Within this work, the pairing mechanism of conventional (Pb) and unconventional superconductors (SrFe2(As1-xPx )2 , FeSe, FeSe/STO) was investigated experimentally by means of elastic and inelastic tunneling spectroscopy ...
Design Space Exploration zur multikriteriellen Optimierung elektrischer Sportwagenantriebsstränge: Variation von Topologie und Komponenteneigenschaften zur Steigerung von Fahrleistungen und Tank-to-Wheel Wirkungsgrad
(2016)
The link between drivetrain topology and energy consumption for all electric sports cars is analyzed. The drivetrain topology is varied along with the characteristics of the used components to find a system optimum instead ...
Design studies towards a 4 MW 170 GHz coaxial-cavity gyrotron
(2011)
In this work the feasibility of a 4 MW 170 GHz coaxial-cavity gyrotron for continuous wave operation is demonstrated. For the first time complete physical designs of the major gyrotron components are elaborated. In a first ...
Diffraktive Optiken im Automobil - Achromatisierung, Athermalisierung, Formung von Scheinwerferlichtverteilungen
