This is partly due to missing powerful lead-free piezoelectric ceramic parts in the commercial market. There has been much research on lead-free materials but developing them into marketable parts seems to be an ongoing process. The actual exemption of ROHS has expired, but as the new exemption has already been requested, ceramic suppliers keep on selling lead containing products. 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.

At the beginning of the 1950s, the first ultrasonic cleaning devices finally came onto the market. Today, the range of applications ranges from household appliances for jewellery and eyewear cleaning to classic cleaning baths for metal parts and systems for cleaning highly sensitive electronic components. There is a certain gap in handheld, mobile cleaning equipment. Although devices for spot cleaning of textiles are known, the cleaning effect is usually low. \r\nDue to the directive 2011/65/EU on the restriction of the use of hazardous substances in electrical and electronic equipment (RoHS) [1] lead should no longer be used in technical devices. As today’s standard ceramics for medium and high-power ultrasonic transducers typically contain lead, there is a need to explore the use of lead-free ceramics in this field. Honda [2] already offers a cleaning transducer based on lead-free piezoelectric ceramics, but it is designed to be used in cleaning baths.\r\nThis article presents the model-based development of a highly innovative ultrasonic cleaner. On the one hand, lead-free piezoelectric ceramics are used, and on the other hand, a special sonotrode has been developed that concentrates the sound in such a way that a strong cavitation and thus cleaning effect is achieved with comparatively low power in a short time. Coupled field finite element method was used to find an appropriate geometry for the focussing sonotrode. The comparison of simulation and measurement results shows that the lead-free piezoceramics used do their job well and can keep up with standard ceramics, but more ceramic volume is needed to achieve same power. An advanced control concept was elaborated to ensure continuous hard cavitation at varying distances between the sonotrode and the part to be cleaned. Cleaning results for different surfaces and contaminations are presented. The concept of the focusing sonotrode shows that a convincing cleaning result can be achieved even with low power and in short time, provided that the oscillation system and control electronics are suitably coordinated.\r\n\r\nReferences\r\n[1] http://data.europa.eu/eli/dir/2011/65/2024-08-01 \r\n[2] https://en.honda-el.co.jp/product/ceramics/lineup/lead_off/lead-off \r\n"}],"citation":{"bibtex":"@inproceedings{Hemsel_Scheidemann_Bornmann_Littmann_Sextro_2025, title={Intensive ultrasonic cleaning of surfaces by means of lead-free ultrasonic transducer with focussing sonotrode}, author={Hemsel, Tobias and Scheidemann, Claus and Bornmann, Peter and Littmann, Walter and Sextro, Walter}, year={2025} }","ama":"Hemsel T, Scheidemann C, Bornmann P, Littmann W, Sextro W.

Vor diesem Hintergrund untersucht das vorliegende Paper die Rolle der Kreislaufwirtschaft als wegweisendes Wirtschaftsmodell, das von der Europäischen Union gefördert wird. Ziel der Kreislaufwirtschaft ist es, den Ressourcenverbrauch und die Abfallproduktion zu minimieren, indem ein kontinuierlicher Kreislauf aus Nutzung, Wiederverwendung und Recycling von Materialien geschaffen wird. \r\nEin zentraler Aspekt dabei ist der Produktentwicklungsprozess (PEP) - ein vielschichtiger Prozess mit zahlreichen Einflussfaktoren und theoretisch unbegrenzten Gestaltungsmöglichkeiten. Diese Vielfalt führt jedoch zu erheblichen Entscheidungsunsicherheiten, die die Umsetzung von Kreislaufwirtschaftsprinzipien erschweren können. Um diese Herausforderungen zu adressieren, wird ein methodischer Prozess vorgestellt, der eine systematische Klassifizierung im Zusammenhang mit umliegenden Bauteilen ermöglicht. Die Methodik basiert auf einer strukturierten Bewertung von Bauteilen hinsichtlich ihrer Relevanz für die Kreislaufwirtschaft. Dabei werden zentrale Aspekte wie Wiederverwendbarkeit, Recyclingfähigkeit und Ressourceneffizienz berücksichtigt, darunter: \r\n•\tHandelt es sich um ein Gebrauchs- oder Verbrauchsprodukt?\r\n•\tIst das Bauteil eine Wiederverwendung oder eine Neufertigung?\r\n•\tIst das Bauteil standardisiert, zugekauft oder individuell ausgerichtet?\r\n•\tWelche primäre Funktion nimmt das Bauteil ein?\r\nDiese strukturierte Klassifizierung unterstützt die Entscheidungsfindung bereits früh im PEP. Sie ermöglicht es Produktentwickelnden, Potenziale für die Kreislaufwirtschaft frühzeitig zu erkennen und gezielt nachhaltige Maßnahmen zu ergreifen.\r\nDie entwickelte Methodik bildet somit eine Grundlage für die Integration kreislaufwirtschaftlicher Prinzipien in den Entwicklungsprozess. Insbesondere im Kontext moderner Anforderungen des Mobility Management zeigt sich ihr Potenzial, nachhaltige Innovationen gezielt zu fördern und die Umsetzung der Kreislaufwirtschaft in der industriellen Praxis zu erleichtern."}],"publication":"Solving Conflicts on the Way to Sustainable Mobility: Technische und betriebswirtschaftliche Aspekte"},{"date_updated":"2026-03-03T13:57:25Z","has_accepted_license":"1","year":"2025","status":"public","title":"Modellgestützte Optimierung eines Ultraschall-Torsionsschweißsystems","author":[{"full_name":"Dohmen, Markus Daniel","first_name":"Markus Daniel","last_name":"Dohmen","id":"69217"},{"full_name":"Bornmann, Peter","last_name":"Bornmann","first_name":"Peter"},{"full_name":"Littmann, Walter","last_name":"Littmann","first_name":"Walter"},{"last_name":"Hemsel","first_name":"Tobias","full_name":"Hemsel, Tobias","id":"210"},{"id":"21220","first_name":"Walter","last_name":"Sextro","full_name":"Sextro, Walter"}],"user_id":"210","ddc":["620"],"_id":"64804","language":[{"iso":"eng"}],"abstract":[{"lang":"ger","text":"Das Ultraschallschweißen ist in der Verpackungs-, Halbleiter- und Automobilindustrie weit verbreitet. Neben dem Schweißen von Blechen bietet es die Möglichkeit, Folien oder Hülsen zu verschweißen. Konventionelle Schweißsysteme arbeiten mit Längs- oder Biegeschwingungen, deren Hauptanteil in der Schweißebene liegt. Der orthogonale Anteil verursacht zusätzliche Belastungen im Schweißgut. Bei der Verwendung von Torsionsschwingungen wird die orthogonale Komponente der Schwingung nahezu eliminiert. \r\nIn diesem Beitrag wird ein System vorgestellt, bei dem die Torsionsschwingung durch tangentiale Polarisation der Piezokeramiken erzeugt wird. Der Transducer ist axial oberhalb des Schweißpunktes platziert, sodass die Normalkraft momentfrei aufgebracht wird. Das Schweißwerkzeug weicht beim Schweißvorgang daher seitlich nicht aus. Zudem wird das Schweißen an schwer zugänglichen Positionen vereinfacht, da der Systemaufbau deutlich schlanker ist als konventionelle Ultraschallschweißsysteme.\r\nDie Auslegung des Torsionsschwingsystems stellt eine Herausforderung dar. Insbesondere muss die Lagerung des Schwingers betrachtet werden, da diese die Normalkraft übertragen und zugleich die Schwingung nicht beeinträchtigen soll. Der Schweißprozess bewirkt eine Verschiebung von Schwingungsknoten und Resonanzfrequenzen. Im Rahmen des Vortrags wird ein Finite-Elemente-Simulationsmodell vorgestellt, das in Kombination mit einem Lastmodell das Systemverhalten während des Schweißprozesses abbildet. Die Geometrie des Transducers wurde schrittweise so angepasst, dass die Schwingamplitude im Lagerungspunkt minimiert wird.  \r\n"}],"file_date_updated":"2026-03-02T12:01:28Z","citation":{"mla":"Dohmen, Markus Daniel, et al. <i>Modellgestützte Optimierung Eines Ultraschall-Torsionsschweißsystems</i>. 2025.","apa":"Dohmen, M.

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.

This has led to the emergence of a field called Social XAI, which is concerned with understanding how explanations are actively shaped in the interaction between a human user and an AI system. Recognizing this turn in XAI toward making XAI systems more “social” by providing explanations that focus on human information needs and incorporating insights from human–human explanatory interactions, in this paper we provide a formal foundation for Social XAI. We do so by proposing novel ontological accounts of the key terms used in Social XAI based on Basic Formal Ontology (BFO). Specifically, we provide novel ontological accounts for explanandum, explanans, understanding, explanation, explainer, explainee, and context. In doing so, we discuss multifaceted entities in Social XAI (having both continuant and occurrent facets; e.g., explanation) and the relationship between understanding and explanation. Additionally, we propose solutions to seemingly paradoxical views on some terms (e.g., social constructivist vs. individual constructivist perspective on explanandum)."}],"extern":"1","date_created":"2025-09-08T14:00:45Z","department":[{"_id":"660"}],"type":"book_chapter","conference":{"name":"15th International Conference on Formal Ontology in Information Systems","start_date":"2025-09-08","location":"Catania, Italy","end_date":"2025-09-12"},"status":"public","_id":"61150","publisher":"IOS Press","page":"255–268","user_id":"76456","citation":{"short":"M.

However, the knowledge contained therein cannot be fully utilized without finding links between the entities contained in these datasets. Equivalent entities can not be identified solely by checking the equivalence of IRIs because of the different origins and naming schemes of different data providers. Yet, such equivalences can be discovered by computing the similarity of their attributes. In this paper we propose GLIDE, an approach that links entities from two different datasets by embedding a joint model of these datasets enriched by additional relations describing the similarity of literals. The joint model is embedded into a latent vector space while paying attention to juxtaposing similar literals. We evaluate our approach against state-of-the-art algorithms using real-world datasets commonly used in link discovery literature. The results show that GLIDE outperforms all baselines on 5 of 7 datasets with perfect or near-perfect accuracy. Our approach achieves its best performance on datasets that feature several literals with similarities. Our experiments indicate that researchers should not only pay attention to equal literals in knowledge graph embedding but should also be aware of the distance between similar literals."}],"place":"Nara, Japan","date_created":"2025-09-11T10:04:16Z","department":[{"_id":"574"}],"keyword":["becker sherif enexa sailproject dice simba ngonga whale"],"type":"conference","conference":{"name":"ISWC 2025"},"author":[{"full_name":"Becker, Alexander","last_name":"Becker","first_name":"Alexander"},{"id":"65716","full_name":"Ngonga Ngomo, Axel-Cyrille","first_name":"Axel-Cyrille","last_name":"Ngonga Ngomo"},{"full_name":"Sherif, Mohamed ","first_name":"Mohamed ","last_name":"Sherif"}],"status":"public","title":"GLIDE: Knowledge Graph Linking using Distance-Aware Embeddings","year":"2025","date_updated":"2025-09-11T10:34:52Z","_id":"61202","language":[{"iso":"eng"}],"user_id":"67234"},{"date_updated":"2025-09-11T10:32:16Z","title":"Leveraging Cognitive States for Adaptive Scaffolding of Understanding in\n  Explanatory Tasks in HRI","status":"public","year":"2025","author":[{"full_name":"Groß, André","last_name":"Groß","first_name":"André"},{"last_name":"Richter","first_name":"Birte","full_name":"Richter, Birte"},{"first_name":"Bjarne","last_name":"Thomzik","full_name":"Thomzik, Bjarne"},{"full_name":"Wrede, Britta","first_name":"Britta","last_name":"Wrede"}],"user_id":"93405","_id":"61213","abstract":[{"lang":"eng","text":"Understanding how scaffolding strategies influence human understanding in\nhuman-robot interaction is important for developing effective assistive\nsystems.

In an adaptive strategy, the user state with respect to the\ncurrent state of understanding and processing capacity was estimated via a\nscoring scheme based on task performance, prior scaffolding strategy, and\ncurrent eye gaze behavior.

Our findings indicate that using adaptive\nscaffolding strategies with SHIFT tends to (1) increased processing costs, as\nreflected in longer reaction times, but (2) improved task understanding,\nevidenced by a lower error rate of almost 23%. We assessed the efficiency of\nSHIFT's selected scaffolding strategies across different cognitive states,\nfinding that in three out of five states, the error rate was lower compared to\nthe baseline condition.
