As a result, we require newer vulnerability detection methods to ensure software security without compromising efficiency. The Code Property Graph (CPG) is a program representation that provides a comprehensive overview of program behavior, combining abstract syntax trees, control flow graphs, and program dependence graphs. With such a detailed data structure, we can detect patterns that characterize known vulnerabilities and identify various security threats. Querying the combined data structure instead of the individual graphs enables the detection of multidimensional scenarios. This work aims to integrate the advantages of CPGs into software systems that utilize the Jimple intermediate representation. We introduce JimNode, a novel approach for generating CPGs specifically tailored to Jimple. Despite the model incompatibility, our evaluation, which covered approximately 50,800 methods, reveals an 88.07% similarity of the inter-statement edges compared to Joern, the state-of-the-art tool for CPG generation. We provide a detailed analysis of our methodology and discuss why it is better suited for Jimple programs than Joern’s language-agnostic approach.}}, author = {{Youkeim, Michael Hany Fawzy}}, publisher = {{Paderborn University}}, title = {{{Tailoring Code Property Graphs to Jimple}}}, year = {{2024}}, } @inproceedings{54312, author = {{Büttner, Markus and Alt, Christoph and Kenter, Tobias and Köstler, Harald and Plessl, Christian and Aizinger, Vadym}}, booktitle = {{Proceedings of the Platform for Advanced Scientific Computing Conference (PASC)}}, publisher = {{ACM}}, title = {{{Enabling Performance Portability for Shallow Water Equations on CPUs, GPUs, and FPGAs with SYCL}}}, doi = {{10.1145/3659914.3659925}}, year = {{2024}}, } @inproceedings{54356, abstract = {{Although there are numerous design and control methodologies for the LLC resonant converter, they often do not consider decentralized control strategies to operate them as isolated DC-DC converters within a cascaded H-bridge. The total output power of all LLC converters must be constant to supply a load such as a wa- ter electrolyzer. However, each individual LLC converter can vary its output power as long as the total output power remains constant. This opens new possibilities in increasing the system efficiency and robustness. Usually, the DC-link voltage of each module capacitor shows a 2nd harmonic voltage ripple. However, the total stored energy in all DC-link capacitors is constant within a grid period for a balanced three-phase system. By controlling each LLC converter’s output power locally to be proportional to the energy stored in its DC-link capacitor, modules with a lower instantaneous DC-link voltage transfer less power to the load than modules with a higher DC-link voltage. As a result, a higher efficiency, voltage gain and lower peak resonant capacitor voltage can be achieved with the same components. The 22.2kW experimental prototype of the LLC converter reaches an efficiency of over 97% at resonance which is similar to the precalculated value.}}, author = {{Unruh, Roland and Böcker, Joachim and Schafmeister, Frank}}, booktitle = {{ECCE Europe 2024; IEEE Energy Conversion Congress & Exposition Europe}}, isbn = {{979-8-3503-6444-6}}, keywords = {{Cascaded H-Bridge, Converter Losses, Decentralized Control, Full-Bridge Converter, LLC Resonant Converter}}, location = {{Darmstadt, Germany}}, publisher = {{IEEE}}, title = {{{Experimentally Verified 22 kW, 40 kHz LLC Resonant Converter Design with new Control for a 1 MW Cascaded H-Bridge Converter}}}, doi = {{https://doi.org/10.1109/ECCEEurope62508.2024.10751954}}, year = {{2024}}, } @inproceedings{57528, abstract = {{Based on the surface equivalence principle an equivalent near-field source can be determined by measurements with a near-field scanner.

Due to a limited signal-to-noise ratio in practical applications, noise adds to the near-field source. Hence, noise effects affect the quality of the simulation results and cause uncertainties. The influence of the noise effects is investigated by a simulative approach with artificially added noise. Two test devices with different a geometric dimension, operating frequency and excited power are evaluated for different characteristics and signal-to-noise ratios to assess the impact of the simulation results.

Mostly, they occur in dialogical form where an explainer discusses a concept or phenomenon of interest with an explainee. Leaving the explainee with a clear understanding is not straightforward due to the knowledge gap between the two participants. Previous research looked at the interaction of explanation moves, dialogue acts, and topics in successful dialogues with expert explainers. However, daily-life explanations often fail, raising the question of what makes a dialogue successful. In this work, we study explanation dialogues in terms of the interactions between the explainer and explainee and how they correlate with the quality of explanations in terms of a successful understanding on the explainee{’}s side. In particular, we first construct a corpus of 399 dialogues from the Reddit forum {Explain Like I am Five} and annotate it for interaction flows and explanation quality. We then analyze the interaction flows, comparing them to those appearing in expert dialogues. Finally, we encode the interaction flows using two language models that can handle long inputs, and we provide empirical evidence for the effectiveness boost gained through the encoding in predicting the success of explanation dialogues.}}, author = {{Alshomary, Milad and Lange, Felix and Booshehri, Meisam and Sengupta, Meghdut and Cimiano, Philipp and Wachsmuth, Henning}}, booktitle = {{Proceedings of the 2024 Joint International Conference on Computational Linguistics, Language Resources and Evaluation (LREC-COLING 2024)}}, editor = {{Calzolari, Nicoletta and Kan, Min-Yen and Hoste, Veronique and Lenci, Alessandro and Sakti, Sakriani and Xue, Nianwen}}, pages = {{11523–11536}}, publisher = {{ELRA and ICCL}}, title = {{{Modeling the Quality of Dialogical Explanations}}}, year = {{2024}}, } @inproceedings{57895, abstract = {{In our paper, we present a study in which we investigate which strategies pre-service teachers (PSTs) use to find and, if necessary, reject possible candidates for congruence theorems for quadrilaterals.
