Second, I point to areas for future research. Third, I deduce policy implications from the studies under review. In sum, the studies show that taxes distort banks’ pricing decisions, the relative attractiveness of debt and equity financing, the decision to report on or off the balance sheet and banks’ investment allocations.

As a result, it ultimately slows down the adoption of machine learning approaches in softwarised networks.

One approach to do so is app merging. We implemented the Android Merge Tool (AMT) following this approach and show that its novel aspects can be used to produce scaled up and accurate benchmarks. For such benchmarks Android app analysis tools do not suffer from the scalability-accuracy trade-off anymore. We show this throughout detailed experiments on DROIDBENCH employing three different analysis tools (AMANDROID, ICCTA, FLOWDROID). Benchmark execution times are largely reduced without losing benchmark accuracy. Moreover, we argue why AMT is an advantageous successor of the state-of-the-art app merging tool (APKCOMBINER) in analysis lift-up scenarios.}}, author = {{Pauck, Felix and Zhang, Shikun}}, booktitle = {{2019 34th IEEE/ACM International Conference on Automated Software Engineering Workshop (ASEW)}}, isbn = {{9781728141367}}, keywords = {{Program Analysis, Android App Analysis, Taint Analysis, App Merging, Benchmark}}, title = {{{Android App Merging for Benchmark Speed-Up and Analysis Lift-Up}}}, doi = {{10.1109/asew.2019.00019}}, year = {{2019}}, } @article{15875, author = {{Camberg, Alan Adam and Tröster, Thomas and Bohner, F. and Tölle, J.}}, issn = {{1757-899X}}, journal = {{IOP Conference Series: Materials Science and Engineering}}, pages = {{012057}}, title = {{{Predicting plasticity and fracture of severe pre-strained EN AW-5182 by Yld2000 yield locus and Hosford-Coulomb fracture model in sheet forming applications}}}, doi = {{10.1088/1757-899X/651/1/012057}}, volume = {{651}}, year = {{2019}}, } @misc{15883, author = {{Kumar Jeyakumar, Shankar}}, title = {{{Incremental learning with Support Vector Machine on embedded platforms}}}, year = {{2019}}, } @inproceedings{15908, author = {{Müller, Jens and Brinkmann, Marcus and Poddebniak, Damian and Böck, Hanno and Schinzel, Sebastian and Somorovsky, Juraj and Schwenk, Jörg}}, booktitle = {{28th {USENIX} Security Symposium ({USENIX} Security 19)}}, isbn = {{978-1-939133-06-9}}, pages = {{1011--1028}}, publisher = {{{USENIX} Association}}, title = {{{"Johnny, you are fired!" -- Spoofing OpenPGP and S/MIME Signatures in Emails}}}, year = {{2019}}, } @inproceedings{15909, author = {{Merget, Robert and Somorovsky, Juraj and Aviram, Nimrod and Young, Craig and Fliegenschmidt, Janis and Schwenk, Jörg and Shavitt, Yuval}}, booktitle = {{28th {USENIX} Security Symposium ({USENIX} Security 19)}}, isbn = {{978-1-939133-06-9}}, pages = {{1029--1046}}, publisher = {{{USENIX} Association}}, title = {{{Scalable Scanning and Automatic Classification of TLS Padding Oracle Vulnerabilities}}}, year = {{2019}}, } @inproceedings{15910, author = {{Engelbertz, Nils and Mladenov, Vladislav and Somorovsky, Juraj and Herring, David and Erinola, Nurullah and Schwenk, Jörg}}, booktitle = {{Open Identity Summit 2019}}, editor = {{Roßnagel, Heiko and Wagner, Sven and Hühnlein, Detlef}}, pages = {{ 95--106 }}, publisher = {{Gesellschaft für Informatik, Bonn}}, title = {{{Security Analysis of XAdES Validation in the CEF Digital Signature Services (DSS)}}}, year = {{2019}}, } @misc{15920, abstract = {{Secure hardware design is the most important aspect to be considered in addition to functional correctness. Achieving hardware security in today’s globalized Integrated Cir- cuit(IC) supply chain is a challenging task. One solution that is widely considered to help achieve secure hardware designs is Information Flow Tracking(IFT). It provides an ap- proach to verify that the systems adhere to security properties either by static verification during design phase or dynamic checking during runtime. Proof-Carrying Hardware(PCH) is an approach to verify a functional design prior to using it in hardware. It is a two-party verification approach, where the target party, the consumer requests new functionalities with pre-defined properties to the producer. In response, the producer designs the IP (Intellectual Property) cores with the requested functionalities that adhere to the consumer-defined properties. The producer provides the IP cores and a proof certificate combined into a proof-carrying bitstream to the consumer to verify it. If the verification is successful, the consumer can use the IP cores in his hardware. In essence, the consumer can only run verified IP cores. Correctly applied, PCH techniques can help consumers to defend against many unintentional modifications and malicious alterations of the modules they receive. There are numerous published examples of how to use PCH to detect any change in the functionality of a circuit, i.e., pairing a PCH approach with functional equivalence checking for combinational or sequential circuits. For non-functional properties, since opening new covert channels to leak secret information from secure circuits is a viable attack vector for hardware trojans, i.e., intentionally added malicious circuitry, IFT technique is employed to make sure that secret/untrusted information never reaches any unclassified/trusted outputs. This master thesis aims to explore the possibility of adapting Information Flow Tracking into a Proof-Carrying Hardware scenario. It aims to create a method that combines Infor- mation Flow Tracking(IFT) with a PCH approach at bitstream level enabling consumers to validate the trustworthiness of a module’s information flow without the computational costs of a complete flow analysis.}}, author = {{Keerthipati, Monica}}, publisher = {{Universität Paderborn}}, title = {{{A Bitstream-Level Proof-Carrying Hardware Technique for Information Flow Tracking}}}, year = {{2019}}, } @inproceedings{15921, abstract = {{Ranking plays a central role in a large number of applications driven by RDF knowledge graphs. Over the last years, many popular RDF knowledge graphs have grown so large that rankings for the facts they contain cannot be computed directly using the currently common 64-bit platforms. In this paper, we tackle two problems: Computing ranks on such large knowledge bases efficiently and incrementally. First, we present D-HARE, a distributed approach for computing ranks on very large knowledge graphs. D-HARE assumes the random surfer model and relies on data partitioning to compute matrix multiplications and transpositions on disk for matrices of arbitrary size. Moreover, the data partitioning underlying D-HARE allows the execution of most of its steps in parallel. As very large knowledge graphs are often updated periodically, we tackle the incremental computation of ranks on large knowledge bases as a second problem. We address this problem by presenting I-HARE, an approximation technique for calculating the overall ranking scores of a knowledge without the need to recalculate the ranking from scratch at each new revision. We evaluate our approaches by calculating ranks on the 3 × 10^9 and 2.4 × 10^9 triples from Wikidata resp. LinkedGeoData. Our evaluation demonstrates that D-HARE is the first holistic approach for computing ranks on very large RDF knowledge graphs. In addition, our incremental approach achieves a root mean squared error of less than 10E−7 in the best case.

For a sample of 100 countries for the year 2016, we find that the level of tax complexity varies considerably across countries, while tax code and framework complexity also vary within countries. From a global perspective, tax complexity is strongly driven by the complexity of both transfer pricing regulations in the tax code and tax audits in the tax framework. When analyzing the associations with other country characteristics, we identify different correlation patterns. For example, tax framework complexity is negatively associated with countries’ governance, suggesting that strongly governed countries tend to have less complex tax frameworks, while tax code complexity is positively associated with the statutory tax rate, indicating that high tax countries tend to have more complex tax codes.

Within the scope of this study, an intrinsically lubricated deep drawing die fabricated via laser beam melting (LBM) is investigated. In contrast to the common objective of generating highly dense LBM components, this work endeavors to achieve intended micro-scale porosity. By utilizing permeable structures, in-process closed-loop control of lubrication during the forming operations is feasible. Based on a modified AM scan strategy, the required filigree, porous structures can be generated. Thus, in the present work three permeable specimens are additively generated from the maraging steel 1.2709. The cylindrical specimens are then analyzed via light microscopy (LM), microcomputer tomography (microCT), and with regard to the oil throughput rate. Subsequently, an intrinsically lubricated, AM deep drawing tool die is manufactured and experimentally tested. The findings reveal interesting results for deep drawn specimens with AM deep drawing dies.}}, author = {{Bader, Fabian and Hengsbach, Florian and Hoyer, Kay-Peter and Homberg, Werner and Schaper, Mirko}}, booktitle = {{PROCEEDINGS OF THE 22ND INTERNATIONAL ESAFORM CONFERENCE ON MATERIAL FORMING: ESAFORM 2019}}, title = {{{Intrinsically lubricated tool inserts for deep drawing applications generated by selective laser melting}}}, doi = {{10.1063/1.5112720}}, year = {{2019}}, } @article{15028, abstract = {{Friction-spinning is an incremental forming process, which is accompanied by complex thermal and mechanical loads in the tool and the formed part. To influence the process temperature, two main process parameters, i.e. the rotation speed and the feed rate, can be adapted. With the objective to improve the tool performance and the quality of the workpiece, this study focuses on a coating concept for friction-spinning tools made of high speed steel (HS6 5 2C, 1.3343). On the one hand, atmospheric plasma sprayed (APS) Al2O3 and ZrO2-8Y2O3 coatings serve as a thermal insulator, and, on the other hand, physically vapor deposited (PVD) TiAlSi7.9N and CrAlSi7.5N films are applied to increase the hardness and wear resistance of the tools. In addition, duplex coatings, combining the APS and PVD technique, are synthesized to influence both the heat transfer and the tribological properties of friction-spinning tools. Subsequently, all coated tools are tested in a friction-spinning process to form flanges made of AW-6060 (AlMgSi 3.3206) tube materials. The tool temperatures are determined in-situ to investigate the impact of the tool coating on the process temperature. Compared to an uncoated tool, the alumina and zirconia coatings contribute to a reduction of the tool temperature by up to half, while the PVD films increase the hardness of the tool by 20 GPa. Furthermore, it is shown that the surface quality of thermally sprayed (TS) or PVD coated tools is directly related to the surface roughness of the resulting workpiece. }}, author = {{Tillmann, Wolfgang and Fehr, Alexander and Stangier, Dominic and Dildrop, Markus and Homberg, Werner and Lossen, Benjamin and Hijazi, Dina}}, issn = {{0944-6524}}, journal = {{Production Engineering}}, pages = {{449--457}}, title = {{{Al2O3/ZrO2-8Y2O3 and (Cr,Ti)AlSiN tool coatings to influence the temperature and surface quality in friction-spinning processes}}}, doi = {{10.1007/s11740-019-00899-y}}, year = {{2019}}, } @phdthesis{15030, abstract = {{Working-media-based forming processes (WMBF) represent a great potential regarding the production of complex sheet-metal lightweight components with excellent surface quality, shape accuracy and dimensional stability. The working-media-based forming processes characterize the sheet-metal forming process, where the sheet metal blank is formed during the forming process by means of a (quasi-)static or dynamic working media pressure into a contouring forming tool. Although the WMBF offers improved utilization of the formability of the used materials compared to conventional sheet metal forming processes, there are limits in the production of complex deeper or sharp edged components with (quasi-)static and dynamic WMBF processes, which can not be overcome by using these methods alone. In order to overcome this, multi-level WMBF process sequences for components with spherical and stepped geometries are developed in this work. Here the developed strategies combine the advantages of (quasi-)static and dynamic WMBF processes. Furthermore, based on analytical, experimental and numerical investigations, innovative process management strategies were derived, which completely compensate the local wall thickness changes, make better use of existing material resources and thus enable the safe production of mentioned geometries.}}, author = {{Djakow, Eugen}}, keywords = {{High Speed Forming}}, pages = {{188}}, publisher = {{Shaker}}, title = {{{Ein Beitrag zur kombinierten (quasi-)statischen und dynamischen Umformung von blechförmigen Halbzeugen}}}, doi = {{ISBN 978-3-8440-6723-1}}, year = {{2019}}, } @article{15031, author = {{Linnemann, M. and Psyk, V. and Djakow, Eugen and Springer, R. and Homberg, W. and Landgrebe, D.}}, issn = {{2351-9789}}, journal = {{Procedia Manufacturing}}, pages = {{21--26}}, title = {{{High-Speed Incremental Forming – New Technologies For Flexible Production Of Sheet Metal Parts}}}, doi = {{10.1016/j.promfg.2018.12.038}}, year = {{2019}}, } @article{15036, author = {{Piper, M. and Zibart, A. and Djakow, Eugen and Springer, R. and Homberg, W. and Kenig, E.Y.}}, issn = {{1359-4311}}, journal = {{Applied Thermal Engineering}}, pages = {{142--146}}, title = {{{Heat transfer enhancement in pillow-plate heat exchangers with dimpled surfaces: A numerical study}}}, doi = {{10.1016/j.applthermaleng.2019.02.082}}, year = {{2019}}, } @inproceedings{15080, author = {{Hartel, Rita and Dunst, Alexander}}, booktitle = {{International Conference on Multimedia Modeling, MMM}}, isbn = {{9783030057152}}, issn = {{0302-9743}}, location = {{Thessaloniki, Greece}}, pages = {{662--671}}, publisher = {{Springer}}, title = {{{How Good Is Good Enough?
