Ultrasound Tomography is an emerging technology for medical imaging that is quickly approaching its clinical utility. Research groups around the globe are engaged in research spanning from theory to practical applications. The International Workshop on Medical Ultrasound Tomography (1.-3. November 2017, Speyer, Germany) brought together scientists to exchange their knowledge and discuss new ideas and results in order to boost the research in Ultrasound Tomography.

By using COSMO-ART, highly resolved process study simulations for 2-3 July 2016 are conducted to assess the aerosol effect on the meteorological conditions of southern West Africa. The meteorological phenomenon Evening Monsoon Flow Enhancement (EMFE) is identified as highly susceptible to the aerosol direct effect, leading to a spatial shift of the EMFE front. In a second aerosol feedback chain the aerosol variation leads to a temporal shift of the stratus-to-cumulus transition.

Single crystalline, µm-sized cantilevers are fabricated out of epitaxially grown Ag thin films by a lithography-based procedure and are deflected by a nanoindenter system. The microstructure of the plastically deformed cantile-vers is investigated using transmission Kikuchi diffraction (TKD) on the cantilever cross section. 3D discrete dislocation dynamics simulations (DDD) are performed for further analysis. A mechanism to explain the formation of dislocation networks upon loading is suggested.

In dieser Arbeit wird das oxidische Material Li₁₊ₓAlₓTi₂₋ₓ(PO₄)₃ (LATP) im Detail auf seine Eignung als Festkörperelektrolyt untersucht. Ausgehend von der Rohmaterialherstellung von LATP mittels Sol-Gel-Methoden über die Pulveraufbereitung bis zur Sinterung vollkeramischer Proben wird der vollständige Herstellungsprozess von LATP abgebildet und analysiert. In this work, the oxide material Li₁₊ₓAlₓTi₂₋ₓ(PO₄)₃ (LATP) is extensively investigated with the scope of using it as a solid state electrolyte. Starting with the synthesis of raw LATP material by sol-gel process, the whole production process of LATP is analyzed, including powder conditioning and sintering of ceramic samples.

Die Arbeit befasst sich mit dem vielschichtigen Interessenausgleich sowie der technikrechtlichen Regulierung an der Schnittstelle von Energiewirtschaftsrecht und Datenschutzrecht. Im Smart Grid wird für die Optimierung von Regulierungswissen ein Verfahren der Bundesnetzagentur vorgeschlagen. Durch dessen Anreicherung um Aspekte der datenschutzkonformen Technikgestaltung kann eine Komplexitätsreduzierung auch durch Visualisierung - angelehnt an das Bau- und Planungsrecht - erreicht werden. This work is concerned with regulation and the reconciliation of interests at the interface of energy sector and privacy law. To improve regulatory knowledge within the Smart Grid, an existing procedure of the Federal Network Agency is proposed. By enriching this procedure through aspects of data protection compliant technical engineering and elements of visualisation - drawn from construction and planning law - it is also possible to reduce the complexity of regulatory knowledge generation.

Modelle, die das Verhalten einer Lithium-Ionen Batterie beschreiben können, sind sowohl für die Produktentwicklung als auch für die zuverlässige Steuerung des Batteriebetriebs durch ein Batteriemanagementsystem unabdingbar. In dieser Arbeit wird ein Modell entwickelt, parametriert und validiert, das in der Lage ist, das elektrische Verhalten einer Lithium-Ionen Zelle während ihrer gesamten Lebensdauer zu prädizieren. Models that can describe the behavior of a lithium-ion battery are indispensable for product development as well as for the reliable control of the battery operation by a battery management system. In this work a model is developed, parametrized and validated that can predict the electric behavior of a lithium-ion cell throughout its entire lifetime.

In this work, we present a modelling approach in order to depict service rules holistically. The developed model is called multi-queue system with multiple departure streams (MQSMDS). The MQSMDS is modelled as a discrete time Markov chain. On the basis of a numerical study, the system characteristics are evaluated. The results of this work enable a rapid and low-cost analysis of material handling and production systems as well as a fast and easy identification of suitable service rules.

In dieser Arbeit wird ein prädiktives Regelungskonzept für multimodale Energieverteilsysteme vorgestellt. Zunächst wird ein durchgängiges Modellierungskonzept für alle Arten von multimodalen Verteilnetzzellen entwickelt. Mithilfe dieser Modelle wird dann eine modellprädiktive Regelungsstrategie zum optimalen Betrieb des multimodalen Energieverteilsystems entworfen. Die Ergebnisse zeigen, dass sowohl eine Betriebskostenreduktion, als auch eine lokalere Nutzung von EE erreicht werden kann. This work presents a model predictive control for Multi-Carrier Energy (MCE) systems. Therefore a general modeling concept for all kind of MCE distribution grids is developed. Based on these models a predictive control strategy for the optimal operation of the system is designed. The results show that by using this control scheme a more locale use of renewables or a significant reduction of the operation costs can be achieved.

This book shows how arbitrary acoustic wavefronts can be encoded in the thickness profile of a phase plate - the acoustic hologram. The workflow for design and implementation of these elements has been developed and is presented in this work along with examples in microparticle assembly, object propulsion and levitation in air. To complement these results, a fast thermographic measurement technique has been developed to scan and validate 3D ultrasound fields in a matter of seconds.

The operation frequency of superconducting integrated THz receivers can be enhanced by replacing the commonly used elementary niobium with niobium nitride. This work presents the technology development of high-quality niobium nitride thin films and superconductor-insulator-superconductor multilayers along with the simulation and realization of high-frequency circuits for a superconducting integrated THz receiver using niobium nitride electrodes.
