Die Kombination aus Prüfung unter Temperatureinfluss und in situ Computertomographie (CT) eröffnet neue Möglichkeiten für die Fügeprozessanalyse. Dazu wurde dazu eine Thermokammer entwickelt und in eine bestehende in situ CT-Anlage integriert. Anwendungsszenarien sind die Herstellung und Prüfung von Fügepunkten unter Temperatur. Die Erwärmung erfolgt über einzeln regelbare Heizzonen, welche eine gezielte Temperaturführung über die gesamte Probengeometrie ermöglichen.

Nevertheless, these should be replaced by lead-free alternatives for environmental and health issues. \r\nThis contribution focuses on exploring the technological readiness level of lead-free hard piezoceramics for prestressed ultrasonic transducers. A small series of bolted Langevin transducers was set up with standard PZT material and three commercial lead-free variants. Results of the building process from individual ring ceramic characteristics to transducer load tests are presented. The main finding of this study is that the lead-free materials technically can compete with the standard PZT for medium-power applications. Some adaptations in the ultrasonic system must be done: the geometry must be altered to fit resonance frequency, and higher voltages or thinner ceramics are needed to achieve the same vibration level at low load. For reaching same power, the volume of lead-free ceramics must be 1.5 to 3 times larger. As already promoted in literature, mechanical losses at high vibration levels are smaller for the lead-free materials. This might help to argument lead-free piezoelectric materials in some applications.\r\n\r\nReferences\r\n1.\tDirective 2011/65/EU of the European Parliament and of the Council of 8 June 2011 on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment.

Yet students’ digital competences often vary significantly, largely influenced by socio-economic background. Some schools—termed “resilient schools”—effectively counter these disadvantages and foster high digital competence. This study investigates the prevalence of such schools and examines how they differ from others. (2) Methods: Drawing on representative ICILS 2023 data, quantitative secondary analyses—including descriptive statistics, t-tests, and multiple regression—were conducted. Following the identification of resilient schools, in-depth analyses focus on those countries with substantial proportions of resilient schools above 10 percent (Austria, Italy, and Portugal), as these countries seem to have effective strategies to foster school resilience. (3) Results: The findings highlight considerable cross-national variation, indicating that school resilience is context-dependent. Resilient schools consistently emphasise student learning-related factors—such as ICT-related attitudes and educational aspirations—while the influence of home environments is less pronounced than in other schools. (4) Conclusions: Strengthening student learning-related factors appears to be crucial for building digital resilience.

However, the structural and semantic differences among these graphs necessitate training or fine-tuning a tailored model for each one. In this paper, we propose UniQ-Gen, a unified query generation approach to generate SPARQL queries across various knowledge graphs. UniQ-Gen integrates entity recognition, disambiguation, and linking through a BERT-NER model and employs cross-encoder ranking to align questions with the Freebase ontology. We conducted several experiments on different benchmark datasets such as LC-QuAD 2.0, GrailQA, and QALD-10. The evaluation results demonstrate that our approach achieves performance equivalent to or better than models fine-tuned for individual knowledge graphs. This finding suggests that fine-tuning a unified model on a heterogeneous dataset of SPARQL queries across different knowledge graphs eliminates the need for separate models for each graph, thereby reducing resource requirements.","lang":"eng"}],"doi":"https://doi.org/10.1007/978-3-031-77792-9_11","_id":"57324","page":"174–189","date_updated":"2024-11-22T12:58:59Z","publication":"Knowledge Engineering and Knowledge Management","date_created":"2024-11-22T12:56:54Z","publisher":"Springer Nature Switzerland","publication_identifier":{"isbn":["978-3-031-77792-9"]},"year":"2025","type":"conference","language":[{"iso":"eng"}],"status":"public"},{"status":"public","year":"2025","publication_identifier":{"isbn":["978-3-11-152346-0"]},"language":[{"iso":"ger"}],"publisher":"DeGruyter","date_created":"2024-05-08T14:13:58Z","date_updated":"2025-01-08T15:54:30Z","_id":"54106","intvolume":"       166","place":"Berlin/Boston","author":[{"first_name":"Tillmann","full_name":"Heise, Tillmann","id":"103827","last_name":"Heise"}],"department":[{"_id":"5"}],"publication_status":"published","series_title":"Studien und Texte zur Sozialgeschichte der Literatur","citation":{"ama":"Heise T. <i>Das ‚andere‘ Europa der Schriftsteller.

The robots' simplicity imply a\r\nstrong limitation: When the initial configuration is rotationally symmetric,\r\nonly patterns with a similar symmetry can be formed [Yamashita, Suzyuki; TCS\r\n2010]. The only known algorithm to form large patterns with limited visibility\r\nand without memory requires the robots to start in a near-gathering (a swarm of\r\nconstant diameter) [Hahn et al.; SAND 2024]. However, not only do we not know\r\nany near-gathering algorithm guaranteed to preserve symmetry but most natural\r\ngathering strategies trivially increase symmetries [Castenow et al.; OPODIS\r\n2022].\r\n  Thus, we study near-gathering without changing the swarm's rotational\r\nsymmetry for disoriented, oblivious robots with limited visibility (the\r\nOBLOT-model, see [Flocchini et al.; 2019]). We introduce a technique based on\r\nthe theory of dynamical systems to analyze how a given algorithm affects\r\nsymmetry and provide sufficient conditions for symmetry preservation. Until\r\nnow, it was unknown whether the considered OBLOT-model allows for any\r\nnon-trivial algorithm that always preserves symmetry. Our first result shows\r\nthat a variant of Go-to-the-Average always preserves symmetry but may sometimes\r\nlead to multiple, unconnected near-gathering clusters. Our second result is a\r\nsymmetry-preserving near-gathering algorithm that works on swarms with a convex\r\nboundary (the outer boundary of the unit disc graph) and without holes (circles\r\nof diameter 1 inside the boundary without any robots)."}],"doi":"10.4230/LIPIcs.OPODIS.2024.13","project":[{"grant_number":"453112019","_id":"106","name":"Algorithmen für Schwarmrobotik: Verteiltes Rechnen trifft Dynamische Systeme"}],"title":"Symmetry Preservation in Swarms of Oblivious Robots with Limited  Visibility","external_id":{"arxiv":["2409.19277"]},"main_file_link":[{"url":"https://arxiv.org/abs/2409.19277","open_access":"1"}],"keyword":["Swarm Algorithm","Swarm Robots","Distributed Algorithm","Pattern Formation","Limited Visibility","Oblivious"],"user_id":"97359","oa":"1","type":"conference","publication":"28th International Conference on Principles of Distributed Systems (OPODIS 2024)","volume":324,"intvolume":"       324","author":[{"last_name":"Gerlach","id":"32655","full_name":"Gerlach, Raphael","first_name":"Raphael","orcid":"0009-0002-4750-2051"},{"last_name":"von der Gracht","id":"97359","full_name":"von der Gracht, Sören","first_name":"Sören","orcid":"0000-0002-8054-2058"},{"full_name":"Hahn, Christopher","first_name":"Christopher","last_name":"Hahn"},{"full_name":"Harbig, Jonas","first_name":"Jonas","id":"47213","last_name":"Harbig"},{"first_name":"Peter","full_name":"Kling, Peter","last_name":"Kling"}],"editor":[{"full_name":"Bonomi, Silvia","first_name":"Silvia","last_name":"Bonomi"},{"full_name":"Galletta, Letterio","first_name":"Letterio","last_name":"Galletta"},{"full_name":"Rivière,  Etienne","first_name":" Etienne","last_name":"Rivière"},{"last_name":"Schiavoni","first_name":" Valerio","full_name":"Schiavoni,  Valerio"}],"conference":{"end_date":"2024-12-13","location":"Lucca, Italy","start_date":"2024-12-11","name":"28th International Conference on Principles of Distributed Systems (OPODIS 2024)"},"department":[{"_id":"101"}],"publication_status":"published","citation":{"apa":"Gerlach, R., von der Gracht, S., Hahn, C., Harbig, J., &#38; Kling, P.
