The idea is to provide a possibility to change the objective in real-time, e.g. as a reaction to changes in the environment or the system state itself. The algorithm utilises elements from various well-established concepts, namely multiobjective optimal control, economic as well as explicit model predictive control and motion planning with motion primitives. In order to realise real-time applicability, we split the computation into an online and an offline phase and we utilise symmetries in the open-loop optimal control problem to reduce the number of multiobjective optimal control problems that need to be solved in the offline phase. The results are illustrated using the example of an electric vehicle where the longitudinal dynamics are controlled with respect to the concurrent objectives arrival time and energy consumption.}}, author = {{Peitz, Sebastian and Schäfer, Kai and Ober-Blöbaum, Sina and Eckstein, Julian and Köhler, Ulrich and Dellnitz, Michael}}, issn = {{2405-8963}}, journal = {{Proceedings of the 20th World Congress of the International Federation of Automatic Control (IFAC)}}, number = {{1}}, pages = {{8674--8679}}, title = {{{A multiobjective MPC approach for autonomously driven electric vehicles}}}, doi = {{10.1016/j.ifacol.2017.08.1526}}, volume = {{50}}, year = {{2017}}, } @inproceedings{29430, author = {{Gail, T. and Ober-Blöbaum, Sina and Leyendecker, S. }}, booktitle = {{ECCOMAS Thematic Conference on Multibody Dynamics}}, title = {{{Variational multirate integration in discrete mechanics and optimal control}}}, year = {{2017}}, } @misc{13078, author = {{Kampmann, Matthias and Hellebrand, Sybille}}, keywords = {{WORKSHOP}}, title = {{{X-tolerante Prüfzellengruppierung für den Test mit erhöhter Betriebsfrequenz}}}, year = {{2017}}, } @inproceedings{10576, author = {{Kampmann, Matthias and Hellebrand, Sybille}}, booktitle = {{20th IEEE International Symposium on Design & Diagnostics of Electronic Circuits & Systems (DDECS'17)}}, isbn = {{9781538604724}}, publisher = {{IEEE}}, title = {{{Design-for-FAST: Supporting X-tolerant compaction during Faster-than-at-Speed Test}}}, doi = {{10.1109/ddecs.2017.7934564}}, year = {{2017}}, } @misc{31301, author = {{Schütte, Philipp}}, title = {{{Identifying and Realizing Symmetries in Quantum Walks - Symmetry Classes and Quantum Walks}}}, year = {{2017}}, } @article{31268, author = {{Faure, Frédéric and Weich, Tobias}}, issn = {{0010-3616}}, journal = {{Communications in Mathematical Physics}}, keywords = {{Mathematical Physics, Statistical and Nonlinear Physics}}, number = {{3}}, pages = {{755--822}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Global Normal Form and Asymptotic Spectral Gap for Open Partially Expanding Maps}}}, doi = {{10.1007/s00220-017-3000-0}}, volume = {{356}}, year = {{2017}}, } @article{31272, author = {{Harris, Benjamin and Weich, Tobias}}, issn = {{0001-8708}}, journal = {{Advances in Mathematics}}, keywords = {{General Mathematics}}, pages = {{176--236}}, publisher = {{Elsevier BV}}, title = {{{Wave front sets of reductive Lie group representations III}}}, doi = {{10.1016/j.aim.2017.03.025}}, volume = {{313}}, year = {{2017}}, } @inproceedings{31370, author = {{Hoffmann, Max and Biehler, Rolf}}, booktitle = {{Beiträge zum Mathematikunterricht 2017}}, editor = {{Kortenkamp, Ulrich and Kuzle, Ana}}, pages = {{441--444}}, publisher = {{WTM-Verlag}}, title = {{{Schnittstellenaufgaben für die Analysis I – Konzept, Beispiele und Evaluationsergebnisse}}}, doi = {{10.17877/DE290R-18534}}, year = {{2017}}, } @inbook{31857, author = {{Häsel-Weide, Uta and Nührenbörger, M.}}, booktitle = {{Gemeinsam Mathematik lernen - mit allen Kindern rechnen.}}, editor = {{Häsel-Weide, Uta and Nührenbörger, M.}}, pages = {{8--21}}, publisher = {{Grundschulverband e.

This complements a previous result of T. Povel, who considered the same question in the case where the drift is strictly smaller than the intensity. We also show that the end point of the process conditioned on survival up to time t rescaled by √t converges in distribution to a non-trivial random variable, as t tends to infinity, which is in fact invariant with respect to the drift h>0. We thus prove that it is sub-ballistic and estimate the speed of escape.

As of today, users wishing to pass this data to their favorite applications, e.g., their calendars, cookbooks, price comparison applications or even smart devices such as TV receivers, rely on cumbersome and error-prone workarounds such as reentering the data or a series of copy and paste operations. In this paper, we present Semantic Data Mediator (SDM), an approach that allows the easy transfer of semantic data to a multitude of services, ranging from web services to applications installed on different devices. SDM extracts semantic data from the currently displayed web page on the client-side, offers suitable services to the user, and by the press of a button, forwards this data to the desired service while doing all the necessary data conversion and service interface adaptation in between. To realize this, we built a reusable repository of service descriptions, data converters, and service adapters, which can be extended by the crowd. Our approach for linking services to websites relies solely on semantic data and does not require any additional support by either website or service developers.
