Since Augmented Reality\r\n(AR) faces similar challenges, it is used as the 5G application. This research aims\r\nto determine the extent to which a learning unit using 5G and AR for collaborative\r\nwork can increase the intention to use these technologies in the vocational setting\r\nand gathers the factors that make up 5G acceptance. It is based on the Technology Acceptance Model 2 (TAM2). The sample includes 23 industrial mechanics\r\nstudents who participated in the developed learning unit. All items are scored on\r\nseven-tiered Likert scales (0 “totally disagree”; 6 “totally agree”).\r\nThe results showed a non-significant change in behavioural intention to use\r\n5G, 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\r\n3.12 (SD: 1.38) at pre-test to 3.37 (SD: 1.16) at post-test. The factors Perceived\r\nUsefulness, Image, and Relevance had the lowest mean scores, indicating areas for\r\ntargeted improvement. The significant change in Output Quality ratings is likely to\r\nreflect initial overestimation by students. The difference in Behavioural Intentions\r\nbetween 5G and AR suggests that AR may not be an effective technology for\r\nincreasing 5G adoption in educational contexts. One recommendation is to address\r\n5G in the learning unit not only indirectly."}],"series_title":"Lecture Notes in Networks and Systems","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://link.springer.com/chapter/10.1007/978-3-031-83520-9_8"}],"doi":"10.1007/978-3-031-83520-9_8","author":[{"id":"68949","full_name":"Schäfers, Johannes","last_name":"Schäfers","first_name":"Johannes"},{"full_name":"Temmen, Katrin","first_name":"Katrin","last_name":"Temmen","id":"30086"}],"publication_identifier":{"issn":["2367-3370","2367-3389"],"isbn":["9783031835193","9783031835209"]},"year":"2025","title":"The Influence of an Immersive-Collaborative Learning Unit on the Technology Acceptance of 5G and AR of Industrial Mechanic Students","intvolume":"      1281","date_updated":"2026-03-17T13:49:57Z","publication_status":"published","place":"Cham","citation":{"ieee":"J.

While this comes with many advantages such as a more efficient economy, it has also created more and more opportunities for various adversaries to manipulate communication or eavesdrop on it. The Snowden revelations in 2013 further highlighted the seriousness of these threats. To protect the communication of people, companies, and states from such threats, we require cryptography with strong security guarantees.\r\nDifferent applications may require different security properties from cryptographic schemes. For most applications, however, so-called adaptive security is considered a reasonable minimal requirement of security. Cryptographic schemes with adaptive security remain secure in the presence of an adversary that can corrupt communication partners to respond to messages of the adversaries choice, while the adversary may choose the messages based on previously observed interactions.\r\nWhile cryptography is associated the most with encryption, this is only one of many primitives that are essential for the security of digital interactions. This thesis presents novel identity-based encryption (IBE) schemes and verifiable random functions (VRFs) that achieve adaptive security as outlined above. Moreover, the cryptographic schemes presented in this thesis are proven secure in the standard model. That is without making use of idealized models like the random oracle model."}],"doi":"10.25926/rdtq-jw45","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://elpub.bib.uni-wuppertal.de/servlets/DerivateServlet/Derivate-14686/de2107.pdf","open_access":"1"}],"date_updated":"2022-02-07T13:32:28Z","publication_status":"published","author":[{"first_name":"David","last_name":"Niehues","full_name":"Niehues, David","id":"36113"}],"year":"2022","title":"More Efficient Techniques for Adaptively-Secure Cryptography","oa":"1","project":[{"_id":"1","name":"SFB 901: SFB 901"},{"_id":"4","name":"SFB 901 - C: SFB 901 - Project Area C"},{"name":"SFB 901 - C1: SFB 901 - Subproject C1","_id":"13"}],"supervisor":[{"id":"64669","full_name":"Jager, Tibor","first_name":"Tibor","last_name":"Jager"},{"first_name":"Anja","last_name":"Lehmann","full_name":"Lehmann, Anja"}],"citation":{"mla":"Niehues, David. <i>More Efficient Techniques for Adaptively-Secure Cryptography</i>. 2022, doi:<a href=\"https://doi.org/10.25926/rdtq-jw45\">10.25926/rdtq-jw45</a>.","ama":"Niehues D. <i>More Efficient Techniques for Adaptively-Secure Cryptography</i>.; 2022. doi:<a href=\"https://doi.org/10.25926/rdtq-jw45\">10.25926/rdtq-jw45</a>","bibtex":"@book{Niehues_2022, title={More Efficient Techniques for Adaptively-Secure Cryptography}, DOI={<a href=\"https://doi.org/10.25926/rdtq-jw45\">10.25926/rdtq-jw45</a>}, author={Niehues, David}, year={2022} }","apa":"Niehues, D.

However, improvement of their catalytic performance to the same level as state-of-the-art noble metal catalysts requires an in depth understanding of their working principle on an atomic level. As a contribution to this aim, a series of iron oxide catalysts with varying Fe loadings from 1 to 20 wt% immobilized on a γ-Al2O3 support is presented here, and a multidimensional structure–activity correlation is established. The CO oxidation activity is correlated to structural details obtained by various spectroscopic, diffraction, and microscopic methods, such as PXRD, PDF analysis, DRUVS, Mössbauer spectroscopy, STEM-EDX, and XAS. Low Fe loadings lead to less agglomerated but high percentual amounts of isolated, tetrahedrally coordinated iron oxide species, while the absolute amount of isolated species reaches its maximum at high Fe loadings. Consequently, the highest CO oxidation activity in terms of turnover frequencies can be correlated to small, finely dispersed iron oxide species with a large amount of tetrahedrally oxygen coordinated iron sites, while the overall amount of isolated iron oxide species correlates with a lower light-off temperature."}]},{"publication":"2021 Conference on Lasers and Electro-Optics Europe and European Quantum Electronics Conference","citation":{"bibtex":"@inproceedings{Domeneguetti_Conradi_Kleinert_Kießler_Stefszky_Herrmann_Silberhorn_Andersen_Neergaard-Nielsen_Gehring_2021, title={Nonlinear waveguides for integrated quantum light source}, booktitle={2021 Conference on Lasers and Electro-Optics Europe and European Quantum Electronics Conference}, publisher={Optica Publishing Group}, author={Domeneguetti, Renato R. and Conradi, Hauke and Kleinert, Moritz and Kießler, Christian and Stefszky, Michael and Herrmann, Harald and Silberhorn, Christine and Andersen, Ulrik L. and Neergaard-Nielsen, Jonas Schou and Gehring, Tobias}, year={2021}, pages={eb_4_1} }","ama":"Domeneguetti RR, Conradi H, Kleinert M, et al.
