Bei Hochleistungs-Ultraschallanwendungen sind diese Komponenten erheblichen elektrischen und mechanischen Belastungen ausgesetzt, was zum Auftreten nichtlinearer Effekte führt. Um das nichtlineare Materialverhalten piezoelektrischer Keramiken zu charakterisieren, kann eine statische mechanische Last aufgebracht werden, die den mechanischen Arbeitspunkt verschiebt. Durch Variation dieser statischen mechanischen Belastung kann das lineare Verhalten in jedem Betriebspunkt charakterisiert werden, woraufhin die nichtlinearen Eigenschaften des Materials angenähert werden können. Allerdings ist die Sicherstellung einer homogenen mechanischen Last anspruchsvoll. Alternativ kann eine hydrostatische Belastung realisiert werden, indem die Probe in einen Behälter gegeben wird, der mit unter Druck stehendem Fluid gefüllt ist. Dadurch wird eine gleichmäßige Lastverteilung über die Oberfläche der Probe erreicht. In diesem Beitrag wird ein Versuchsaufbau zur Durchführung elektrischer Impedanzmessungen an piezoelektrischen Keramiken in einem Druckbehälter vorgestellt. Die Probe wird im Inneren des Druckbehälters elektrisch kontaktiert. Unter Verwendung von unter Druck stehendem Argon wird auf diese Weise die Messung der elektrischen Impedanz unter hydrostatischer Last von bis zu 200 bar ermöglicht. Anschließend wird ein inverses Verfahren angewendet, um die Materialparameter in Abhängigkeit von der aufgebrachten Last zu ermitteln.}}, author = {{Friesen, Olga and Pasha, Muhammad Ahsan and Schwengelbeck, Max and Claes, Leander and Baumhögger, Elmar and Henning, Bernd}}, booktitle = {{Fortschritte der Akustik - DAGA 2024}}, location = {{Hannover}}, pages = {{1117–1120}}, title = {{{Untersuchung piezoelektrischer Materialeigenschaften unter hydrostatischer Last}}}, year = {{2024}}, } @article{65861, abstract = {{The study examines whether the announcement and passing of the Corporate Sustainability Reporting Directive (CSRD) impacts the sustainability reporting of German firms. It sheds light on the interdependence of various actors, sectors and policy levels by examining how regulatory changes at the policy level affect the reporting practices of firms across multiple sectors. On the one hand, the scope of the CSRD is being extended, so that new firms falling within its scope may increase their voluntary sustainability reporting as part of the preparation process. On the other hand, the reporting requirements will be more stringent, so that firms currently under the mandate of the Non-Financial Reporting Directive (NFRD) may enhance their sustainability reporting disclosure practices in preparation for the CSRD. First, we find no increase in voluntary sustainability reporting by firms that are not under the scope of the NFRD but will be under the scope of the CSRD. Second, we find enhanced sustainability reporting practices by firms that are subject to the NFRD after the CSRD’s announcement and passing. This finding suggests that these firms begin to implement the new reporting requirements before the first reports are published in 2025. We illuminate the preparation for extensive reporting changes through sustainability reporting disclosure practices as an outcome of the preparation process. These changes may represent a high burden, particularly for firms with no previous experience of sustainability reporting.}}, author = {{Kosi, Urska and Relard, Paula}}, issn = {{2948-1627}}, journal = {{Sustainability Nexus Forum}}, number = {{1}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Are firms (getting) ready for the corporate sustainability reporting directive?}}}, doi = {{10.1007/s00550-024-00541-1}}, volume = {{32}}, year = {{2024}}, } @book{66055, abstract = {{This volume examines the Rabbinic, Qur’anic and Christian understandings of prophecy from a historical and comparative theological perspective.

Even for periodic tasks, providing timing guarantees for tasks with segmented self-suspending behavior is challenging due to timing anomalies, i.e., the reduction of execution or suspension time of some jobs increases the response time of another job. The release jitter of tasks can add further complexity to the situation, affecting the predictability and timing guarantees of real-time systems. The existing worst-case response time analyses for sporadic self-suspending tasks are only over-approximations and lead to overly pessimistic results. In this work, we address timing anomalies without compromising the worst-case response time (WCRT) analysis when scheduling periodic segmented self-suspending tasks with release jitter. We propose two treatments: segment release time enforcement and segment priority modification, and prove their effectiveness in eliminating timing anomalies. Our evaluation demonstrates that the proposed treatments achieve higher acceptance ratios in terms of schedulability compared to state-of-the-art scheduling algorithms. Additionally, we implement the segment-level fixed-priority scheduling mechanism on RTEMS and verify the validity of our segment priority modification treatment.

In the case of the Laplace–Beltrami operator, we show that if the initial data are bi-K-invariant, then the solution to the extension problem behaves asymptotically as the mass times the fundamental solution, but this convergence may break down in the non-bi-K-invariant case. In the second part, we investigate the long-time asymptotic behavior of the extension problem associated with the so-called distinguished Laplacian on G/K.
