    Description: The design of approaches for future market-based energy network operation faces the technical challenge of needing to coordinate a vast number of network participants spatially and temporally, in order to balance energy supply and demand, while achieving secure network operation. To meet this challenge, the research field of transactive control emerged. Within this work a new transactive control approach for coupled electric power and district heating networks is presented.

    Description: The increasing use of automated laser welding processes causes high demands on process monitoring. This work demonstrates methods that use a camera mounted on the focussing optics to perform pre-, in-, and post-process monitoring of welding processes. The implementation uses machine learning methods. All algorithms consider the integration into industrial processes. These challenges include a small database, limited industrial manufacturing inference hardware, and user acceptance.

    Description: What are the effects of internal migration controls on migrants without a regular residence permit – on “sans papiers”? The book gives an answer to this question with a comparative study of the United States and Germany. Based on expert interviews and in-depth interviews with forty sans papiers, police controls as well as controls in areas such as labor market, health care, housing, schooling and childcare are carefully analysed. The book discusses whether global economic, political or social processes have restricted the ability of advanced capitalist countries to control migration. It argues that migration policy in the OECD countries has become more similar, but this convergence only takes place at the level of policy goals and legal norms. At the level of implementation, national differences persist. The interviews show that sans papiers in the U.S. continue to have many possibilities to participate in society. In contrast, the comprehensive exclusion of sans papiers in Germany confi rms that there is no general “loss of control”.
    Description: Welche Auswirkungen haben interne Migrationskontrollen auf Migrantinnen und Migranten ohne regulären Aufenthaltsstatus - auf »Sans Papiers«? Dieser Frage geht das Buch mit einem Vergleich zwischen den Vereinigten Staaten und Deutschland nach. Anhand von Expertengesprächen und vierzig qualitativen Interviews mit Sans Papiers werden polizeiliche Kontrollen und Kontrollen in den Bereichen Arbeitsmarkt, Gesundheitsversorgung, Wohnen sowie Schule und Kinderbetreuung eingehend untersucht. Das Buch diskutiert, ob globale ökonomische, politische und soziale Prozesse die Fähigkeit von Nationalstaaten einschränken, Migration zu kontrollieren. Es wird gezeigt, dass sich die Migrationspolitik der OECDStaaten in den vergangenen Jahren zwar auf der Ebene der Leitlinien und Gesetze angeglichen hat. Bei der Implementation von Kontrollen bestehen aber nationale Unterschiede fort. Die Interviews belegen, dass Sans Papiers in den USA weiterhin vielfältige Möglichkeiten zur gesellschaftlichen Partizipation haben. Im Gegenzug zeigt das Beispiel Deutschland, dass angesichts der weitgehenden Exklusion von Sans Papiers keine Rede von einem »Kontrollverlust« sein kann.

    Description: Although laser cutting of metals is a well-established process, there is considerable potential for improvement with regard to various requirements for the manufacturing industry. First, this potential is identified and then it is shown how improvements could be made using machine learning. For this purpose, a database was generated. It contains the process parameters, RGB images, 3D point clouds and various quality features of almost 4000 cut edges.

    Description: This work presents a real-time dynamic pricing framework for future electricity markets. Deduced by first-principles analysis of physical, economic, and communication constraints within the power system, the proposed feedback control mechanism ensures both closed-loop system stability and economic efficiency at any given time. The resulting price signals are able to incentivize competitive market participants to eliminate spatio-temporal shortages in power supply quickly and purposively.

    Description: A gyrotron is used in magnetically confined plasma experiments for heating, current drive, plasma stabilization and plasma diagnostics. This work presents the first design and construction of a multi-frequency / multi-purpose coaxial-cavity pre-prototype gyrotron operating at (136)/170/204 GHz with an output power of 2 MW. It is the first step towards operating frequencies up to 240 GHz using the coaxial-cavity gyrotron technology.

    Description: Especially pedestrians rely on the interaction with other road users. The introduction of automated driving systems withdraws this communication from drivers and thus, vehicles need to interact with pedestrians. Therefore, multiple vehicle-pedestrian-communication concepts are evaluated. A driver intention prediction allows pedestrians to learn these newly introduced signals, while driver and vehicle communicate simultaneously.
