It then observes a corresponding (random) reward, provided the (random) amount of consumed resources remains below the limit. Otherwise, the observation is censored, i.e., no reward is obtained. 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. We derive the theoretical lower bound on the cumulative regret and propose a learning algorithm having a regret upper bound that matches the lower bound. In a simulation study, we show that our learning algorithm outperforms straightforward extensions of standard multi-armed bandit algorithms.}}, author = {{Bengs, Viktor and Hüllermeier, Eyke}}, booktitle = {{arXiv:2011.00813}}, title = {{{Multi-Armed Bandits with Censored Consumption of Resources}}}, year = {{2020}}, } @article{21539, author = {{Ortmann, Regina and Pelster, Matthias and Wengerek, Sascha Tobias}}, issn = {{1544-6123}}, journal = {{Finance Research Letters}}, title = {{{COVID-19 and investor behavior}}}, doi = {{10.1016/j.frl.2020.101717}}, year = {{2020}}, } @inproceedings{21541, abstract = {{In this publication, the near-field to far-field transformation using the self-built near-field scanner NFS3000 is examined with regard to its geometry. This device allows to measure electric and magnetic fields in small distances to the DUT (Device under Test) with high geometric precision and high sensitivity. Leading to a fast examination of EMC (Electromagnetic Compatibility) problems, because the electromagnetic properties are better understandable and therefore easier to solve than e.g. measurements in a far-field chamber. In addition, it is possible to extrapolate the near-fields into the far-field and to determine the radiation pattern of antennas and emitting objects. For this purpose, this paper deals with the basis of this transformation, the so-called surface equivalence theorem. This principle is then adapted to the measurement of near-field scanners and implemented accordingly. Due to the non-ideal design of the near-field scanner, the effects on a far-field transformation are finally presented and discussed.}}, author = {{Lange, Sven and Schroder, Dominik and Hedayat, Christian and Hangmann, Christian and Otto, Thomas and Hilleringmann, Ulrich}}, booktitle = {{2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE}}, isbn = {{978-1-7281-5580-7}}, issn = {{2325-0364 }}, keywords = {{Near-Field Scanner, Near-Field to Far-Field Transformation, Directivity, Surface Equivalence Theorem, Huygens’ Box}}, location = {{Rome, Italy }}, publisher = {{IEEE}}, title = {{{Investigation of the Surface Equivalence Principle on a Metal Surface for a Near-Field to Far-Field Transformation by the NFS3000}}}, doi = {{10.1109/emceurope48519.2020.9245697}}, year = {{2020}}, } @inbook{21542, abstract = {{Using near-field (NF) scan data to predict the far-field (FF) behaviour of radiating electronic systems represents a novel method to accompany the whole RF design process. This approach involves so-called Huygens' box as an efficient radiation model inside an electromagnetic (EM) simulation tool and then transforms the scanned NF measured data into the FF. 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}}, }
