@inproceedings{9913, abstract = {{Reconfigurable hardware has received considerable attention as a platform that enables dynamic hardware updates and thus is able to adapt new configurations at runtime. However, due to their dynamic nature, e.g., field-programmable gate arrays (FPGA) are subject to a constant possibility of attacks, since each new configuration might be compromised. Trojans for reconfigurable hardware that evade state-of-the-art detection techniques and even formal verification, are thus a large threat to these devices. One such stealthy hardware Trojan, that is inserted and activated in two stages by compromised electronic design automation (EDA) tools, has recently been presented and shown to evade all forms of classical pre-configuration detection techniques. This paper presents a successful pre-configuration countermeasure against this ``Malicious Look-up-table (LUT)''-hardware Trojan, by employing bitstream-level Proof-Carrying Hardware (PCH). We show that the method is able to alert innocent module creators to infected EDA tools, and to prohibit malicious ones to sell infected modules to unsuspecting customers.}}, author = {{Ahmed, Qazi Arbab and Wiersema, Tobias and Platzner, Marco}}, booktitle = {{Applied Reconfigurable Computing}}, editor = {{Hochberger, Christian and Nelson, Brent and Koch, Andreas and Woods, Roger and Diniz, Pedro}}, isbn = {{978-3-030-17227-5}}, location = {{Darmstadt, Germany}}, pages = {{127--136}}, publisher = {{Springer International Publishing}}, title = {{{Proof-Carrying Hardware Versus the Stealthy Malicious LUT Hardware Trojan}}}, doi = {{10.1007/978-3-030-17227-5_10}}, volume = {{11444}}, year = {{2019}}, } @inproceedings{36529, author = {{Bruns, Julia and Gasteiger, Hedwig}}, booktitle = {{Proceedings of the 43rd Conference of the International Group for the Psychology of Mathematics Education}}, editor = {{Graven, Mellony and Venkat, Hamsa and Essien, Anthony and Vale, Pamela}}, location = {{Pretoria, South Africa}}, pages = {{129--136}}, title = {{{VimaS_num: Measuring situational perception in mathematics of early childhood teachers}}}, volume = {{2}}, year = {{2019}}, } @inproceedings{36542, author = {{Bruns, Julia and Gasteiger, Hedwig}}, booktitle = {{Beiträge zum Mathematikunterricht 2019}}, editor = {{Frank, Andreas and Krauss, Stefan and Binder, Karin}}, location = {{Regensburg}}, pages = {{169--172}}, publisher = {{WTM-Verlag}}, title = {{{Mathematikdidaktischen Wissen von frühpädagogischen Fachkräften aus kognitiv-situationsbezogener Perspektive – Theoretisches Konstrukt und empirische Erfassung}}}, doi = {{10.17877/DE290R-20771}}, year = {{2019}}, } @misc{15874, author = {{Lienen, Christian}}, publisher = {{Universität Paderborn}}, title = {{{Implementing a Real-time System on a Platform FPGA operated with ReconOS}}}, year = {{2019}}, } @article{46803, abstract = {{ABSTRACTDrawing on the political theory of judicial decision making, our paper proposes a new and parsimonious ex ante litigation risk measure: federal judge ideology. We find that judge ideology complements existing measures of litigation risk based on industry membership and firm characteristics. Firms in liberal circuits (the third quartile in ideology) are 33.5% more likely to be sued in securities class action lawsuits than those in conservative circuits (the first quartile in ideology). This result is stronger after the U.S. Supreme Court's ruling in the Tellabs case. We next show that the effect of judge ideology on litigation risk is greater for firms with more sophisticated shareholders and with higher expected litigation costs. Furthermore, judicial appointments affect litigation risk and the value of firms in the circuit, highlighting the economic consequences of political appointments of judges. Finally, using our new measure, we document that litigation risk deters managers from providing long‐term earnings guidance, a result that existing measures of litigation risk cannot show.}}, author = {{HUANG, ALLEN and HUI, KAI WAI and Li, Reeyarn}}, issn = {{0021-8456}}, journal = {{Journal of Accounting Research}}, keywords = {{Economics and Econometrics, Finance, Accounting}}, number = {{2}}, pages = {{431--489}}, publisher = {{Wiley}}, title = {{{Federal Judge Ideology: A New Measure of Ex Ante Litigation Risk}}}, doi = {{10.1111/1475-679x.12260}}, volume = {{57}}, year = {{2019}}, } @inproceedings{13460, abstract = {{Remaining useful lifetime (RUL) predictions as part of a condition monitoring system are focused in more and more research and industrial applications. To establish an efficient and precise estimate of the RUL of a technical product, different uncertainties have to be handled. To minimize the uncertainties of the RUL estimation, a reliable and accurate prognostic approach as well as a good failure threshold are important. Regarding the failure threshold, most often an expert sets a fixed failure threshold. However, neither the a priori known failure threshold nor a fixedthreshold value are feasible in every application. Especially in the case of varying characteristics of the monitored system, an adaptive failure threshold is of great importance concerning the accuracy of the RUL estimation. Rubber-metal-elements, which are used in a wide range of applications for vibration and sound isolation, are mon-itored by thermocouples to allow for lifetime predictions. Therefore, the element’s state is described by its temper-ature during its service life. Aiming to establish accurate RUL predictions of a rubber-metal-element, uncertainties due to nonlinear material characteristics and changing operational conditions have to be considered. Consequently, different temperature-based failure threshold definitions are implemented and compared within a particle filtering approach. }}, author = {{Bender, Amelie and Schinke, Lennart and Sextro, Walter}}, booktitle = {{Proceedings of the 29th European Safety and Reliability Conference (ESREL2019)}}, editor = {{Beer, Michael and Zio, Enrico}}, isbn = {{978-981-11-2724-3}}, keywords = {{RUL prediction, adaptive threshold, prognostics, condition monitoring}}, location = {{Hannover}}, number = {{29}}, pages = {{1262--1269}}, title = {{{Remaining useful lifetime prediction based on adaptive failure thresholds}}}, year = {{2019}}, } @article{12871, author = {{Platzner, Marco and Plessl, Christian}}, issn = {{0170-6012}}, journal = {{Informatik Spektrum}}, title = {{{FPGAs im Rechenzentrum}}}, doi = {{10.1007/s00287-019-01187-w}}, year = {{2019}}, } @inproceedings{13461, abstract = {{As the emerging digitalization of technical systems offers immense opportunities to be exploited by means of bigdata analysis, ubiquitous computing and largely networked systems, the digital twin comes into focus to combineall these aspects to an attendant model of an individual system during design phase as well as during operation.Since state-of-art technical systems are growing increasingly complex due to inherent intelligence and increasingfunctionality, i. e. autonomous behavior so far, it becomes considerably challenging to ensure reliability for thosesystems.

In field, data-based methods, i. e. condition monitoring enabled bythe rise of machine learning approaches, are exploited to ensure a reliable operation based on the current conditionof the monitored system. In order to take advantage of existing models of system reliability during design phaseand condition monitoring systems during operation, a method is proposed to combine both approaches in order toset up a digital twin with focus on system reliability.

There is a consequently a clear need to curate question answering benchmarks periodically. However, the manual alteration of question answering benchmarks is often error-prone. We alleviate this problem by presenting QUANT, a novel framework for the creation and curation of question answering benchmarks. QUANT sup-ports the curation of benchmarks by generating smart edit suggestions for question-query pair and for the corresponding metadata. In addition, our framework supports the creation of new benchmark entries by pro-viding predefined quality checks for queries.

So zeigt sich dahingehend ein Ländereffekt, dass in Deutschland digitale Instrumente stärker genutzt werden als in Österreich. Darüber hinaus haben Auflagen seitens der Verbände zur Verwendung bestimmter Software (z.B. für die Meldung von Wettkampfergebnissen) einen wichtigen Einfluss.
