@inbook{65032, abstract = {{Despite its status as a key enabling technology, the adoption of 5G in industry remains limited, mainly due to a lack of expertise, which can be addressed by incorporating 5G training into vocational schools. Since Augmented Reality (AR) faces similar challenges, it is used as the 5G application. This research aims to determine the extent to which a learning unit using 5G and AR for collaborative work can increase the intention to use these technologies in the vocational setting and gathers the factors that make up 5G acceptance. It is based on the Technology Acceptance Model 2 (TAM2). The sample includes 23 industrial mechanics students who participated in the developed learning unit. All items are scored on seven-tiered Likert scales (0 “totally disagree”; 6 “totally agree”). The results showed a non-significant change in behavioural intention to use 5G, with a mean of 4.95 (SD: 1.18) for the pre-test and 4.43 (SD: 1.68) for the posttest. The change in intention to use AR did not change significantly either, from 3.12 (SD: 1.38) at pre-test to 3.37 (SD: 1.16) at post-test. The factors Perceived Usefulness, Image, and Relevance had the lowest mean scores, indicating areas for targeted improvement. The significant change in Output Quality ratings is likely to reflect initial overestimation by students. The difference in Behavioural Intentions between 5G and AR suggests that AR may not be an effective technology for increasing 5G adoption in educational contexts. One recommendation is to address 5G in the learning unit not only indirectly.}}, author = {{Schäfers, Johannes and Temmen, Katrin}}, booktitle = {{Proceedings of the 27th International Conference on Interactive Collaborative Learning (ICL2024), Volume 4}}, editor = {{Auer, Michael E. and Rüütmann, Tiia}}, isbn = {{9783031835193}}, issn = {{2367-3370}}, keywords = {{5G, Key Technology, TAM · Augmented Reality, VET}}, location = {{Tallinn}}, pages = {{84 – 91}}, publisher = {{Springer Nature Switzerland}}, title = {{{The Influence of an Immersive-Collaborative Learning Unit on the Technology Acceptance of 5G and AR of Industrial Mechanic Students}}}, doi = {{10.1007/978-3-031-83520-9_8}}, volume = {{1281}}, year = {{2025}}, } @article{60566, author = {{Bocchini, Adriana and Rüsing, Michael and Bollmers, Laura and Lengeling, Sebastian and Mues, Philipp and Padberg, Laura and Gerstmann, Uwe and Silberhorn, Christine and Eigner, Christof and Schmidt, Wolf Gero}}, issn = {{2475-9953}}, journal = {{Physical Review Materials}}, number = {{7}}, publisher = {{American Physical Society (APS)}}, title = {{{Mg dopants in lithium niobate: Defect models and impact on domain inversion}}}, doi = {{10.1103/5wz1-bjyr}}, volume = {{9}}, year = {{2025}}, } @inproceedings{64905, author = {{Bienvenu, Meghyn and Bourgaux, Camille and Khodadaditaghanaki, Atefe}}, booktitle = {{Proceedings of the Thirty-Fourth International Joint Conference on Artificial Intelligence, {IJCAI-25}}}, editor = {{Kwok, James}}, pages = {{4374–4381}}, publisher = {{International Joint Conferences on Artificial Intelligence Organization}}, title = {{{Inconsistency Handling in DatalogMTL}}}, doi = {{10.24963/ijcai.2025/487}}, year = {{2025}}, } @inproceedings{65034, author = {{Schäfers, Johannes and Vernholz, Mats and Jonas-Ahrend, Gabriela and Temmen, Katrin}}, location = {{Potsdam}}, title = {{{Vom Prompt zur Praxis – Kooperatives Seminarkonzept zur KI-gestützten Unterrichtsentwicklung in der gewerblich-technischen Lehramtsausbildung}}}, year = {{2025}}, } @inproceedings{65038, abstract = {{The rapid advancements in digital transformation have led to the emergence of dataspaces as a pivotal element for industry-wide and cross-industry data integration and interoperability across various businesses.

In previous studies, a mathematical model was developed to predict the degradation while compounding on different twin-screw extruder sizes. Additionally, the examination of filled PPs was conducted. To this end, a range of operating parameters and extruder sizes were used to process PP, and the molar mass was then determined by melt flow rate (MFR) and gel permeation chromatography (GPC) measurements to derive the degree of degradation. The model was then modified by adjusting the sensitivity parameters to allow the degradation behavior of the PPs to be described independently of extruder size. Consistent with prior research, comprehensive measurements of a PP/titanium dioxide (TiO2) compound revealed that, with a few exceptions, increasing temperatures and screw speeds and decreasing throughputs generally resulted in higher degradation. However, the application of the model to the compounds did not achieve good agreement with the measured degradation, indicating different degradation conditions due to the different thermodynamic and rheological properties of the compounds.}}, author = {{Albrecht, Paul and Altepeter, Matthias and Brüning, Florian}}, issn = {{2073-4360}}, journal = {{Polymers}}, number = {{11}}, publisher = {{MDPI AG}}, title = {{{Degradation of Polypropylene and Polypropylene Compounds on Co-Rotating Twin-Screw Extruders}}}, doi = {{10.3390/polym17111509}}, volume = {{17}}, year = {{2025}}, }
