Using video conferencing systems implies the expectation that online meetings run as smoothly as in-person meetings. Thus, online meetings need to be just as secure and private as in-person meetings, which are secured against disruptive factors and unauthorized persons by physical access control mechanisms. To show the security dangers of conferencing systems and raise general awareness when using these technologies, we analyze the security of two widely used research and education open-source video conferencing systems: BigBlueButton and eduMEET. Because both systems are very different, we analyzed their architectures, considering the respective components with their main tasks, features, and user roles. In the following systematic security analyses, we found 50 vulnerabilities. These include broken access control, NoSQL injection, and denial of service (DoS). The vulnerabilities have root causes of different natures. While BigBlueButton has a lot of complexity due to many components, eduMEET, which is relatively young, focuses more on features than security. The sheer amount of results and the lack of prior work indicate a research gap that needs to be closed since video conferencing systems continue to play a significant role in research, education, and everyday life.}}, author = {{Heitmann, Nico and Siewert, Hendrik and Moog, Sven and Somorovsky, Juraj}}, booktitle = {{Applied Cryptography and Network Security}}, location = {{Abu Dhabi}}, publisher = {{Springer Nature Switzerland}}, title = {{{Security Analysis of BigBlueButton and eduMEET}}}, doi = {{10.1007/978-3-031-54776-8_8}}, year = {{2024}}, } @inbook{54443, abstract = {{Im Gespräch loten Brigitte Leucht und Korinna Schönhärl aus, welche Rolle wirtschafts- und finanzpolitische Überlegungen und Faktoren für den europäischen Einigungsprozess gespielt haben und immer noch spielen. }}, author = {{Schönhärl, Korinna and Leucht, Brigitte}}, booktitle = {{Europäische Einigung zwischen Anspruch und Wirklichkeit.

However, these graph-based methods are limited in their ability to explain classes with multiple sufficient explanations. To provide more expressive explanations, we propose utilizing class expressions (CEs) from the field of description logic (DL). Our approach explains heterogeneous graphs with different types of nodes using CEs in the EL description logic. To identify the best explanation among multiple candidate explanations, we employ and compare two different scoring functions: (1) For a given CE, we construct multiple graphs, have the GNN make a prediction for each graph, and aggregate the predicted scores. (2) We score the CE in terms of fidelity, i.e., we compare the predictions of the GNN to the predictions by the CE on a separate validation set. Instead of subgraph-based explanations, we offer CE-based explanations.}}, author = {{Köhler, Dominik and Heindorf, Stefan}}, booktitle = {{arXiv:2405.12654}}, title = {{{Utilizing Description Logics for Global Explanations of Heterogeneous Graph Neural Networks}}}, year = {{2024}}, } @inproceedings{52231, author = {{Blübaum, Lukas and Heindorf, Stefan}}, booktitle = {{The World Wide Web Conference (WWW)}}, location = {{Singapore}}, pages = {{2204–2215}}, publisher = {{ACM}}, title = {{{Causal Question Answering with Reinforcement Learning}}}, doi = {{10.1145/3589334.3645610}}, year = {{2024}}, } @inproceedings{53638, abstract = {{Abstract. Spring steel wires are usually supplied and stored on coils. The manufacturing and coiling processes of these wires induce inhomogeneous plastic deformations that lead to undesirable residual stresses and varying wire curvatures in the semi-finished product. These residual stresses and curvatures defects are causing varying process conditions in the subsequent manufacturing processes, which have a negative impact on the product quality, leading to wastage and thus affecting the economic and ecological efficiency. Especially the curvature deviations must be compensated for the stability of the subsequent processes. This is usually realised with roller straighteners, which are set manually by the machine operators only at the beginning of a process. In this paper, we introduce a new approach with a modular straightening-machine design and a new set-up process. The more isolated deformation behaviour in a module-based straightener overcomes the complexity of interactions between the close-positioned spaced straightening rollers. This is combined with a set-up process that is independent of conventional material testing, modelling the actual and batch-specific behaviour of the wire in the straightening process. The exact knowledge and time-consuming determination of the material properties thus becomes obsolete. The experimental investigations show the influence of defined straightening strategies on the residual stress evolution and the residual forming limit of the spring steel wires (X10CrNi18-8) in the new straightening process. }}, author = {{Dahms, Frederik Simon and Homberg, Werner}}, booktitle = {{Materials Research Proceedings}}, issn = {{2474-395X}}, location = {{Toulouse}}, publisher = {{Materials Research Forum LLC}}, title = {{{Modular 3D roller straightening – A new approach to straightening and forming of spring steel wires (X10CrNi18-8)}}}, doi = {{10.21741/9781644903131-154}}, year = {{2024}}, } @inbook{54497, abstract = {{Der Beitrag führt in die von uns verfolgte Forschungsperspektive der sozialen Grenzen und Grenzbearbeitungen ein und bringt diese mit den Begriffen Bildung und Bildungsforschung zusammen.
