Es werden sowohl die theoretischen Ergebnisse analysiert als auch die praktische Umsetzung in Simulationen und am Prüfstand untersucht. Das Manöver, welches hier hauptsächlich betrachtet wird, ist der Aufschwung des Pendels aus der stabilen unteren Ruhelage in die instabile obere Ruhelage. Dabei werden mit Hilfe von Methoden der Mehrzieloptimierung viele Varianten von Lösungen berechnet, die die zwei gegenläufigen Zielgrößen Dauer des Manövers und Steueraufwand unterschiedlich stark berücksichtigen. So ist es möglich eine komplexe Bibliothek von optimalen Lösungen zu erhalten und diese weitergehend bezüglich des Gesamtsystemverhaltens zu analysieren. Ein weiterer Ansatz ist die Entwicklung von Strategien für eine optimale Steuerung auf Mannigfaltigkeiten, die besondere dynamische Strukturen des Pendelsystems für einen optimalen Aufschwung nutzen. Auf der stabilen Mannigfaltigkeit kann sich das dynamische System kostenlos in die Ruhelage bewegen. Dies ist somit ein besonderer physikalisch motivierter Ansatz, um optimale Manöver zu finden.}}, author = {{Timmermann, Julia}}, title = {{{Optimale Steuerung und Mehrzieloptimierung von dynamischen Systemen untersucht am Beispiel des Mehrfachpendels}}}, year = {{2014}}, } @article{8171, abstract = {{The polynomial hierarchy plays a central role in classical complexity theory. Here, we define a quantum generalization of the polynomial hierarchy, and initiate its study.

Using the same techniques, we also obtain hardness of approximation for the class QCMA.

While improved concepts of privacy have been suggested, the paper aims to argue that people acting in full conformity to those privacy norms still can infringe the privacy of others in the context of ubiquitous computing and “big data”. Design/methodology/approach – New threats to privacy are described. Helen Nissenbaum's concept of “privacy as contextual integrity” is reviewed concerning its capability to grasp these problems. The argument is based on the assumption that the technologies work, persons are fully informed and capable of deciding according to advanced privacy considerations. Findings – Big data and ubiquitous computing enable privacy threats for persons whose data are only indirectly involved and even for persons about whom no data have been collected and processed. Those new problems are intrinsic to the functionality of these new technologies and need to be addressed on a social and political level. Furthermore, a concept of data minimization in terms of the quality of the data is proposed. Originality/value – The use of personal data as a threat to the privacy of others is established. This new perspective is used to reassess and recontextualize Helen Nissenbaum's concept of privacy. Data minimization in terms of quality of data is proposed as a new concept. }}, author = {{Matzner, Tobias}}, issn = {{1477-996X}}, journal = {{Journal of Information, Communication and Ethics in Society}}, number = {{2}}, pages = {{93--106}}, title = {{{Why privacy is not enough privacy in the context of “ubiquitous computing” and “big data”}}}, doi = {{https://doi.org/10.1108/jices-08-2013-0030}}, volume = {{12}}, year = {{2014}}, } @article{41582, author = {{Fuchs, Christian and Sandoval, Marisol}}, journal = {{tripleC: Communication, Capitalism & Critique}}, number = {{2}}, pages = {{486--563}}, title = {{{Digital Workers of the World Unite!
