  text: "Lead-containing piezoelectric ceramics are still the base for today’s ultrasonic
    transducers used in broad applications. 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

  text: "Intensive ultrasonic cleaning of surfaces by means of a lead-free ultrasonic
    transducer with focusing sonotrode\r\nUltrasonic cleaning baths are probably a
    coincidental development: After underwater sonars had already been successfully
    used to detect submarines before 1920, it was probably observed in this environment
    that the ultrasonic oscillators not only showed a self-cleaning effect but also
    cavitation damage. 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]

  text: 'Artificial intelligence (AI) is driving transformative changes across numerous
    fields, revolutionizing conventional processes and creating new opportunities
    for innovation. The development of mechatronic systems is undergoing a similar
    transformation. Over the past decade, modeling, simulation, and optimization techniques
    have become integral to the design process, paving the way for the adoption of
    AI-based methods. In this paper, we examine the potential for integrating AI into
    the engineering design process, using the V-model from the VDI guideline 2206,
    considered the state-of-the-art in product design, as a foundation. We identify
    and classify AI methods based on their suitability for specific stages within
    the engineering product design workflow. Furthermore, we present a series of application
    examples where AI-assisted design has been successfully implemented by the authors.
    These examples, drawn from research projects within the DFG Priority Program \emph{SPP~2353:
    Daring More Intelligence - Design Assistants in Mechanics and Dynamics}, showcase
    a diverse range of applications across mechanics and mechatronics, including areas
    such as acoustics and robotics.'

  text: "Für die Aufrechterhaltung der natürlichen Ressourcen ist eine effiziente
    Nutzung dieser essenziell. 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."

  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"

  text: '<jats:p>(1) Background: As digitalisation transforms society, digital competences
    are increasingly essential. 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.
    These insights can inform policy and practice aimed at fostering educational equity
    and closing the digital divide, particularly in socio-economically disadvantaged
    contexts.</jats:p>'

  text: 'Die Rolle der Grammatik im Deutschunterricht wird in der sprachdidaktischen
    Forschung intensiv diskutiert. Diese Einführung führt die Diskussion konstruktiv
    fort: Der Band bietet einen erweiterten, oft innovativen Blick auf grammatisches
    Lernen im Primar- und Sekundarbereich, er thematisiert neben den Grundlagen des
    Grammatikerwerbs auch Sprach(en)bewusstheit und Mehrsprachigkeit. Gemäß den aktuellen
    Bildungsstandards für das Fach Deutsch fokussiert er formale und funktionale Aspekte
    von Grammatik. Der Praxisteil liefert Methoden und Konzepte der Vermittlung als
    Best-Practice-Beispiele – nicht nur für Lehramtsstudierende, sondern auch für
    praktizierende Deutschlehrkräfte.'

  text: Generating SPARQL queries is crucial for extracting relevant information from
    diverse knowledge graphs. 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.
