Most standard-model VRFs rely on admissible hash functions (AHFs) to achieve security against adaptive attacks in the standard model. Known AHF constructions are based on error-correcting codes, which yield asymptotically efficient constructions. However, previous works do not clarify how the code should be instantiated concretely in the real world. The rate and the minimal distance of the selected code have significant impact on the efficiency of the resulting cryptosystem, therefore it is unclear if and how the aforementioned constructions can be used in practice. First, we explain inherent limitations of code-based AHFs. Concretely, we assume that even if we were given codes that achieve the well-known Gilbert-Varshamov or McEliece-Rodemich-Rumsey-Welch bounds, existing AHF-based constructions of verifiable random functions (VRFs) can only be instantiated quite inefficiently. Then we introduce and construct computational AHFs (cAHFs). While classical AHFs are information-theoretic, and therefore work even in presence of computationally unbounded adversaries, cAHFs provide only security against computationally bounded adversaries. However, we show that cAHFs can be instantiated significantly more efficiently.

On the other hand, the disclosure of a favourable low ETR could attract the attention of tax auditors and the public and ultimately result in disclosure costs. We empirically test disclosure behaviour by examining the relation between disclosure visibility and different ETR conditions that reflect different stakeholder specific costs and benefits. While we find that unfavourable ETR conditions are not highlighted, we observe higher disclosure visibility for favourable ETRs (smooth, close to the industry average, decreasing).

For this problem setting, we introduce a measure of regret, which incorporates the actual amount of allocated resources of each learning round as well as the optimality of realizable rewards. Thus, to minimize regret, the learner needs to set a resource limit and choose an arm in such a way that the chance to realize a high reward within the predefined resource limit is high, while the resource limit itself should be kept as low as possible.

For this, the basic idea of the Huygens'box principle and the NF-to-FF transformation are briefly presented. The NF is measured on the Huygens' box around a device under test using anNF scanner, recording the magnitude and phase of the site-related magnetic and electric components. A comparison between a fullwave simulation and the measurement results shows a good similarity in both the NF and the simulated and transformed FF.Thus, this method is applicable to predict the FF behaviour of any electronic system by measuring the NF. With this knowledge, the RF design can be improved due to allowing a significant reduction of EM compatibility failure at the end of the development flow. In addition, the very efficient FF radiation model can be used for detailed investigations in various environments and the impact of such an equivalent radiation source on other electronic systems can be assessed.}}, author = {{Schröder, Dominik and Lange, Sven and Hangmann, Christian and Hedayat, Christian}}, booktitle = {{Tensorial Analysis of Networks (TAN) Modelling for PCB Signal Integrity and EMC Analysis}}, isbn = {{9781839530494}}, keywords = {{Huygens' box, NF-to-FF transformation, efficient FF radiation model, FF behaviour, EMI assessment, PCB, near-field measurements, efficient radiation model, far-field behaviour, RF design process, far-field prediction, Huygens'box principle, fullwave simulation, electronic system radiation, equivalent radiation source, electromagnetic simulation tool, near-field scan data, EM compatibility failure reduction}}, pages = {{315--346 (32)}}, publisher = {{ The Institution of Engineering and Technology (IET)}}, title = {{{Far-field prediction combining simulations with near-field measurements for EMI assessment of PCBs}}}, doi = {{10.1049/pbcs072e_ch14}}, year = {{2020}}, } @inbook{21579, author = {{Berger, Thomas and Lanza, Lukas Johannes}}, booktitle = {{Progress in Differential-Algebraic Equations II}}, isbn = {{9783030539047}}, issn = {{2199-7497}}, title = {{{Observers for Differential-Algebraic Systems with Lipschitz or Monotone Nonlinearities}}}, doi = {{10.1007/978-3-030-53905-4_9}}, year = {{2020}}, } @inproceedings{21584, author = {{Gatica, Carlos Paiz and Platzner, Marco}}, booktitle = {{Machine Learning for Cyber Physical Systems (ML4CPS 2017)}}, isbn = {{9783662590836}}, issn = {{2522-8579}}, title = {{{Adaptable Realization of Industrial Analytics Functions on Edge-Devices using Reconfigurable Architectures}}}, doi = {{10.1007/978-3-662-59084-3_9}}, year = {{2020}}, } @article{21608, author = {{Meschede, Henning}}, issn = {{0960-1481}}, journal = {{Renewable Energy}}, pages = {{1480--1491}}, title = {{{Analysis on the demand response potential in hotels with varying probabilistic influencing time-series for the Canary Islands}}}, doi = {{10.1016/j.renene.2020.06.024}}, year = {{2020}}, } @article{17331, author = {{Graf-Schlattmann, Marcel and Meister, Dorothee M. and Oevel, Gudrun and Wilde, Melanie}}, journal = {{Forschungsperspektiven auf Digitalisierung in Hochschulen, Zeitschrift für Hochschulentwicklung}}, number = {{1}}, title = {{{Kollektive Veränderungsbereitschaft als zentraler Erfolgsfaktor von Digitalisierungsprozessen an Hochschulen}}}, volume = {{15}}, year = {{2020}}, } @article{17335, author = {{Hampel, Uwe and Schubert, Markus and Döß, Alexander and Sohr, Johanna and Vishwakarma, Vineet and Repke, Jens‐Uwe and Gerke, Sören J. and Leuner, Hannes and Rädle, Matthias and Kapoustina, Viktoria and Schmitt, Lucas and Grünewald, Marcus and Brinkmann, Jost H. and Plate, Dominik and Kenig, Eugeny and Lutters, Nicole and Bolenz, Lukas and Buckmann, Felix and Toye, Dominique and Arlt, Wolfgang and Linder, Thomas and Hoffmann, Rainer and Klein, Harald and Rehfeldt, Sebastian and Winkler, Thomas and Bart, Hans‐Jörg and Wirz, Dominic and Schulz, Jonas and Scholl, Stephan and Augustin, Wolfgang and Jasch, Katharina and Schlüter, Florian and Schwerdtfeger, Natalie and Jahnke, Stefan and Jupke, Andreas and Kabatnik, Christoph and Braeuer, Andreas Siegfried and D'Auria, Mirko and Runowski, Thomas and Casal, Maria Francisco and Becker, Karsten and David, Anna‐Lena and Górak, Andrzej and Skiborowski, Mirko and Groß, Kai and Qammar, Hina}}, issn = {{0009-286X}}, journal = {{Chemie Ingenieur Technik}}, pages = {{926--948}}, title = {{{Recent Advances in Experimental Techniques for Flow and Mass Transfer Analyses in Thermal Separation Systems}}}, doi = {{10.1002/cite.202000076}}, volume = {{92}}, year = {{2020}}, }
