This article addresses these challenges and introduces the data awareness framework. It focuses on understanding data-driven technologies and reflecting on the role of data in everyday life. The paper also presents an empirical study on young school students' data awareness. The study involves a teaching unit on data awareness framed by a pretest-posttest design using a questionnaire on students' awareness and understanding of and reflection on data practices of data-driven digital artefacts. The study's findings indicate that the data awareness framework supports students in understanding data practices of data-driven digital artefacts. The findings also suggest that the framework encourages students to reflect on these data practices and think about their daily behaviour. Students learn a model about interactions with data-driven digital artefacts and use it to analyse data-driven applications. This approach appears to enable students to understand these artefacts from everyday life and reflect on these interactions. The work contributes to research on data and AI literacies and suggests a way to support students in developing self-determination and agency during interactions with data-driven digital artefacts."}],"language":[{"iso":"eng"}],"doi":"10.1108/ils-06-2023-0075","author":[{"first_name":"Lukas","last_name":"Höper","full_name":"Höper, Lukas","id":"58041"},{"full_name":"Schulte, Carsten","last_name":"Schulte","first_name":"Carsten","id":"60311"}],"publication_identifier":{"issn":["2398-5348","2398-5348"]},"year":"2024","title":"The data awareness framework as part of data literacies in K-12 education","intvolume":"       125","article_type":"original","date_updated":"2024-10-11T12:01:06Z","publication_status":"published","oa":"1","citation":{"apa":"Höper, L., &#38; Schulte, C.

However, the utilization of their network capabilities is often challenging and error-prone because the whole network stack and communication patterns have to be implemented and managed on the FPGAs. Also, this approach conceptually involves a trade-off between the performance potential of improved communication and the impact of resource consumption for communication infrastructure, since the utilized resources on the FPGAs could otherwise be used for computations. In this work, we investigate this trade-off, firstly, by using synthetic benchmarks to evaluate the different configuration options of the communication framework ACCL and their impact on communication latency and throughput. Finally, we use our findings to implement a shallow water simulation whose scalability heavily depends on low-latency communication. With a suitable configuration of ACCL, good scaling behavior can be shown to all 48 FPGAs installed in the system. Overall, the results show that the availability of inter-FPGA communication frameworks as well as the configurability of framework and network stack are crucial to achieve the best application performance with low latency communication.</jats:p>","lang":"eng"}],"publisher":"Springer Nature Switzerland","_id":"56606","user_id":"3145","status":"public","place":"Cham","oa":"1","citation":{"mla":"Meyer, Marius, et al. “Optimizing Communication for Latency Sensitive HPC Applications on up to 48 FPGAs Using ACCL.” <i>Lecture Notes in Computer Science</i>, Springer Nature Switzerland, 2024, doi:<a href=\"https://doi.org/10.1007/978-3-031-69766-1_9\">10.1007/978-3-031-69766-1_9</a>.","apa":"Meyer, M., Kenter, T., Petrica, L., O’Brien, K., Blott, M., &#38; Plessl, C.

The intensive computation and bandwidth demand for ERI evaluation presents a significant challenge for quantum-mechanics-based atomistic simulations with hybrid density functional theory: due to the tens of trillions of ERI computations in each time step, practical applications are usually limited to thousands of atoms. In this work, we propose SERI, a high-throughput streaming accelerator for ERI computation on HBM-based FPGAs. In contrast to prior buffer-based designs, SERI proposes a novel streaming architecture to address the on-chip buffer limitation and the floorplanning challenge, and leverages the high-bandwidth memory to overcome the bandwidth bottleneck in prior designs. Moreover, to meet the varying computation, bandwidth, and floorplanning requirements between the 55 canonical quartet classes in ERI calculation, we design an automation tool, together with an accurate performance model, to automatically customize the architecture and floorplanning strategy for each canonical quartet class to maximize their throughput. Our performance evaluation on the AMD/Xilinx Alveo U280 FPGA board shows that, SERI achieves an average speedup of 9.80 x over the previous best-performing FPGA design, a 3.21x speedup over a 64-core AMD EPYC 7713 CPU, and a 15.64x speedup over an Nvidia A40 GPU. It reaches a peak throughput of 23.8 GERIS ($10^9$ ERIs per second) on one Alveo U280 FPGA. SERI will be released soon at https://github.com/SFU-HiAccel/SERI."}],"main_file_link":[{"url":"https://ieeexplore.ieee.org/document/10705609"}],"language":[{"iso":"eng"}],"doi":"10.1109/fpl64840.2024.00018","year":"2024","title":"SERI: High-Throughput Streaming Acceleration of Electron Repulsion Integral Computation in Quantum Chemistry using HBM-based FPGAs","author":[{"last_name":"Stachura","first_name":"Philip","full_name":"Stachura, Philip"},{"full_name":"Li, Guanyu","last_name":"Li","first_name":"Guanyu"},{"full_name":"Wu, Xin","last_name":"Wu","first_name":"Xin","id":"77439"},{"orcid":"0000-0001-5728-9982","last_name":"Plessl","first_name":"Christian","full_name":"Plessl, Christian","id":"16153"},{"first_name":"Zhenman","last_name":"Fang","full_name":"Fang, Zhenman"}],"publication_status":"published","date_updated":"2024-10-15T08:37:27Z"},{"citation":{"bibtex":"@inproceedings{Möller_Krauter_2024, title={Cost Analysis for a Small-Scale Hybrid, Hydrogen-Based PV Energy System}, booktitle={Proceedings of the 41st European Photovoltaic Solar Energy Conference}, author={Möller, Marius Claus and Krauter, Stefan}, year={2024} }","chicago":"Möller, Marius Claus, and Stefan Krauter. “Cost Analysis for a Small-Scale Hybrid, Hydrogen-Based PV Energy System.” In <i>Proceedings of the 41st European Photovoltaic Solar Energy Conference</i>, 2024.","ama":"Möller MC, Krauter S.

There is growing interest in the challenges students face as they move into more advanced mathematics courses that require a shift toward formal reasoning, proof, modeling, and problem-solving skills. This survey paper explores emerging trends and innovations in the field, focusing on three key areas: innovations in teaching and learning advanced mathematical topics, transitions between different levels and contexts of mathematics education, and the role of proof and proving in advanced university mathematics. The survey reflects the evolving landscape of mathematics education research and addresses the theoretical and practical challenges of teaching and learning advanced mathematics across various contexts.</jats:p>","lang":"eng"}]},{"volume":91,"user_id":"32616","_id":"55519","publisher":"De Gruyter","funded_apc":"1","page":"26-31","conference":{"name":"XXXVIII.

Darüber hinaus kommen in dem Messaufbau Schallwandler zum Einsatz, die eine segmentierte ringförmige Anregung der Probe verursachen und die Sensitivität gegenüber Scherbewegungen erhöhen.

We outline and implement a largely analytic procedure forrigorous modal analysis of three-layer slabs with birefringent, anisotropic core. For Z-cut wave-guides, the slab eigenmode problem separates into uncoupled sets of scalar equations for TE andTM modes. Slabs in X-cut configuration support mostly mildly hybrid eigenmodes, with clear pre-dominant TE or TM polarization, and with effective indices that depend on the propagation directionof the modes, relative to the crystal axes. Strong hybridization can be observed for near degeneratemodes in singular configurations without vertical symmetry, or in symmetric slabs where two nearlydegenerate modes are of the same symmetry class. Dispersion curves for slab thickness and propa-gation angle are discussed, for slabs with oxide and air cover. "}]}]
