  text: <jats:p>This research investigates how Artificial Intelligence (AI) can be
    systematically integrated into existing business processes by combining suitable
    competencies with graphical AI workflow modelling. While AI offers a high potential
    for automation and increased efficiency, its implementation often fails due to
    a lack of interdisciplinary competencies that bridge the gap between domain expertise
    and IT know-how. Low-code platforms and visual modelling tools are increasingly
    recognised as enablers, empowering non-programmers to intuitively create graphical
    AI- based workflows. Nevertheless, specific competencies are required to realise
    the full potential of AI, the domain specific knowledge and align technical understanding
    with AI capabilities. The paper reviews the state of the art in AI-driven business
    process automation and competencies for visual low-code approaches. It then presents
    a practical solution to identify and systematise essential competence areas. Based
    on this, a practical competence model is developed to support the design of user-friendly,
    AI-enabled workflows. This is tested in a practical application context — emergency
    management — where it supports critical decision-making processes and is validated
    through expert feedback. The study concludes by offering actionable recommendations
    to help organisations foster the necessary competencies and methods for competently
    integrating AI into their digital processes.</jats:p>

  text: Zur Steigerung der Ressourceneffizienz technischer Komponenten sind neben
    dem Leichtbau insbesondere neuartige Fertigungstechnologien und Prozessketten
    mit geschlossenen Stoffkreisläufen von großer Bedeutung. Im Beitrag werden am
    Beispiel einer Demonstratorstruktur aus hybriden Leichtbauprofilen (Aluminium
    und faserverstärktes Polyamid) technisch-technologische Lösungsoptionen für die
    gesamte Prozesskette inklusive des Recyclings vorgestellt und in Pilotversuchen
    bewertet.

  text: "Aluminium-Silizium-Legierungen (AlSi) werden insbesondere bei der gießtechnischen\r\nHerstellung
    von Leichtbaukomponenten für Fahrzeuge verwendet. Dieses Legierungssystem hat
    hervorragende\r\nGießeigenschaften bei gleichzeitig akzeptablen mechanischen Eigenschaften.
    Aufgrund des hohen\r\nSilizium-(Si)-Gehaltes, wodurch die Volumenkontraktion im
    Phasenübergang von flüssig-fest nahezu\r\nunterbunden wird, neigen AlSi-Legierungen
    dazu, feinere oder gröbere Si-Platten bei unterschiedlichen\r\nErstarrungsgeschwindigkeiten
    zu bilden. Um die mechanischen Eigenschaften zu verbessern, werden\r\ndem Legierungssystem
    in der Schmelzphase entweder Natrium (Na) oder Strontium (Sr) zugesetzt. Dies\r\nhat
    zur Folge, dass sich eine fein lamellare Si-Morphologie bei der Erstarrung ausbildet;
    dies kann ebenfalls\r\ndurch hohe Erstarrungsgeschwindigkeiten erreicht werden.
    Ein nachfolgendes Lösungsglühen bewirkt\r\neine Sphäroidisierung der Si-Partikel
    und dient der Steigerung der Duktilität. Aktuell fehlen fundierte\r\nErkenntnisse
    zur Ausprägung der Si-Morphologie in Abhängigkeit der Erstarrungsgeschwindigkeit
    oder\r\ninfolge einer Wärmebehandlung. Vor diesem Hintergrund werden in dieser
    Studie verschiedene Behandlungsparameter\r\nin Bezug auf das Einformverhalten
    der Si-Partikel mit einem bildauswertenden Verfahren\r\nevaluiert sowie unter
    Bezug auf verschiedene chemische Zusammensetzungen miteinander korreliert."

  text: "Aluminium-silicon alloys (AlSi) are used in the casting of lightweight vehicle
    components. This\r\nalloy system has excellent casting properties accompanied
    by acceptable mechanical properties. Due to\r\nthe high silicon (Si) content,
    which almost completely prevents volume contraction during the liquid-solid\r\nphase
    transition, AlSi alloys tend to form finer or coarser Si plates at different solidification
    rates. To\r\nimprove the mechanical properties, either sodium (Na) or strontium
    (Sr) is added to the alloy system in\r\nthe melting phase. This results in the
    formation of a fine lamellar Si morphology during solidification, which\r\ncan
    also be achieved by high solidification rates. Subsequent solution annealing causes
    spheroidisation\r\nof the Si particles and increases ductility. Currently, there
    is a lack in scientific knowledge regarding the\r\nSi-morphology as a function
    of solidification rate or as a result of heat treatment. Therefore, this study\r\nevaluates
    various treatment parameters in relation to the shaping behaviour of Si particles
    using an image\r\nanalysis method and correlates them with different chemical
    compositions."

  text: Sandwich packings are assembled from two conventional structured packings
    with different geometrical surface areas stacked alternatingly within a separation
    column. When operated under partially flooded conditions, they provide significant
    mass transfer improvement compared to common structured packings. In this work,
    a rate-based model including novel mass transfer correlations is presented and
    validated using a comprehensive experimental database for the reactive absorption
    of CO2 into aqueous monoethanolamine. The proposed rate-based approach is capable
    of accounting for axial dispersion, thereby enabling the evaluation of the effect
    of liquid-phase backmixing on the mass transfer performance. The validated rate-based
    model is used to evaluate the separation performance of sandwich packings. Compared
    with structured packings, up to 10 % higher mass transfer rates are obtained.

  text: <jats:p>Titanium alloys are widely employed for biomedical implants due to
    their high strength, biocompatibility, and corrosion resistance, yet their lack
    of intrinsic antibacterial activity remains a major limitation. Incorporating
    copper, an antibacterial and β-stabilising element, offers a promising strategy
    to enhance implant performance. This study investigates Ti-6Al-7Nb modified with
    1–9 wt.% Cu via in situ alloying during metal-based laser powder bed fusion (PBF-LB/M),
    with the aim of assessing processability, microstructural evolution, and mechanical
    properties. Highly dense samples (&gt;99.9%) were produced across all Cu levels,
    though chemical homogeneity strongly depended on processing parameters. Increasing
    Cu content promoted β-phase stabilisation, Ti2Cu precipitation, and pronounced
    grain refinement. Hardness and yield strength increased nearly linearly with Cu
    addition, while ductility decreased sharply at ≥5 wt.% Cu due to intermetallic
    formation, hot cracking, and brittle fracture. These results illustrate both the
    opportunities and constraints of rapid alloy screening via PBF-LB/M. Overall,
    moderate Cu additions of 1–3 wt.% provide the most favourable balance between
    mechanical performance, manufacturability, and potential antibacterial functionality.
    These findings provide a clear guideline for the design of Cu-functionalised titanium
    implants and demonstrate the efficiency of in situ alloy screening for accelerated
    materials development.</jats:p>

  text: "The carbon footprint of modern vehicles and their mechatronic systems is
    more\r\nimportant than ever. Research by the publicly funded Nalyses project and
    the HELLA\r\ncompany shows that the headlamps use phase makes a significant contribution
    to the life\r\ncycle footprint taking into account the current electricity mix
    [1]. Today, functionalities\r\nsuch as adaptive curve light or glare-free high
    beam ensure comfort and safety by\r\nassessing the state of the vehicle and evaluating
    the driving scenario ahead. In future,\r\nthis evaluation will be expanded and
    used to adapt the headlamp to the driving scenario\r\nin such a way that as little
    light as possible is emitted, but as much light as necessary. In\r\norder to achieve
    this goal, an overall evaluation of the regulatory compliant energy\r\nsaving
    potential is crucial in a first step and leads to constraints for a dynamic adaption\r\nwhile
    driving. In this paper, the potential is illustrated by evaluating UNECE Regulation\r\nNo.
    149 and optimizing luminous intensity distributions. Depending on the different\r\nresolutions
    of matrix LED headlamps, this approach can result in a significantly lower\r\nluminous
    flux. On the other hand, the results are point-like distributions that raise the\r\nquestion
    of whether the regulation still provides for sensible minimum requirements for\r\nmodern
    matrix LED headlamps. The results are further presented in a simulated virtual\r\nenvironment
    with regard to the resulting luminance in different driving scenarios. We\r\nthen
    present an approach to integrate regulatory requirements into a control algorithm
    by\r\nsetting optimization constraints and saturating the control. Finally, we
    classify the found\r\nluminous intensity distributions qualitatively according
    to common lighting criteria. In summary, although the investigated minimum distributions
    are by no means desirable\r\nfor drivers themselves, they form the basis on which
    energy-saving distributions for\r\nilluminated areas and twilight scenarios could
    be adaptively controlled in the future."

  text: In the context of decarbonization initiatives, the repairability and recyclability
    of components have become a major concern in various industrial sectors, particularly
    for resource-intensive components. The development of innovative bonding and debonding
    processes that must adhere to the stringent mechanical specifications of the manufacturers
    and facilitate their efficient disassembly is a major issue faced in the implementation
    of a sustainable circular economy. Although adhesively bonded joints satisfy the
    stringent requirements for mechanical performance, they present several challenges
    during the repair and recycling process. Solvolytically debondable epoxy resin
    adhesives may be employed to overcome this issue. In this study, we aim to conduct
    an exploratory feasibility study on the application of such chemical debonding
    mechanisms within an adhesive bond as well as to systematically analyse and evaluate
    the suitability of such adhesive systems for various applications. To this end,
    we employed various thermo-analytical methods and quasi-static tensile tests to
    characterise the mechanical adhesive and joint properties of two solvolytically
    debondable adhesive systems. Furthermore, we analysed the debondability of the
    adhesive joints and evaluated their feasibility in an industrial environment.
    The results indicate considerable application potential for solvolytically debondable
    adhesives, along with further development steps currently required.

  text: The integration of data-driven models and specifically machine learning for
    conditon monitoring and predictive maintenance into companies, especially small
    and medium-sized enterprises, offers significant opportunities in reducing costs,
    operating more sustainably, and maintaining long-term competitiveness. However,
    many small and medium-sized enterprises lack the necessary resources and expertise
    to derive knowledge from data and integrate their own machine learning based solutions.
    To address this challenge, a framework is presented that enables the automated
    generation of data-driven models with a particular focus on condition monitoring
    and predictive maintenance, but applicable to other use cases as well. Using a
    dataset from the 2022 data challenge of the prognostics and health management
    society, it is demonstrated that the framework can generate high-performing models,
    achieving F1-scores up to 0.998, exemplarily for a classification task.

  text: <jats:p>Friction-spinning is an incremental thermomechanical forming process
    that has huge potential due to its simple yet effective mechanism of utilising
    friction between a rotating workpiece and a forming tool to increase the workpiece’s
    temperature, which reduces the required forces and increases formability during
    the forming process. Despite the simplicity of the process’s setup, the thermomechanical
    loads and high relative velocities involved, especially in the contact zone, make
    the application of classical methods for characterising friction inaccurate. It
    is therefore essential to find a way to describe the frictional behaviour under
    real process conditions to be able to gain a holistic understanding of the process
    and the effect of the adjustable parameters on the outcome, especially the temperature.
    To achieve this goal, an experimental setup that considers the actual process
    boundary conditions in forming tubes made of EN AW-6060 was used to measure in
    situ normal and frictional forces, in addition to process temperatures, under
    varying rotational speed and feed rate values.</jats:p>

  text: <jats:p>Abstract. Liquid Metal Embrittlement (LME) cracking is a well-documented
    issue encountered during resistance spot welding (RSW) of zinc-coated advanced
    high-strength steels (AHSS) in automotive manufacturing. Given that existing research
    has predominantly focused on laboratory-scale samples and lacks investigation
    into the load-bearing capacity of joints under crash conditions, this study aims
    to fill these gaps by analyzing third-generation zinc-coated AHSS. S-Rail components
    were produced through stamping to replicate real-world manufacturing conditions
    and geometries of automotive parts. To account for the disturbances typically
    encountered in production, samples with LME cracks were intentionally fabricated.
    Subsequently, a modified three-point bending test, assisted by numerical simulations,
    was developed to effectively apply loads to the weld spots of the S-Rail components.
    Results from crash tests demonstrated that observed light crack severity does
    not significantly compromise the joint's load-bearing capacity or lead to earlier
    joint failure.</jats:p>

  text: <jats:p>Abstract. In the field of online condition monitoring, non-destructive
    testing methods using active acoustic testing [1] emerged as innovative tools.
    These techniques are particularly effective because damage in joined structures
    leads to significant changes in their vibrational characteristics. However, the
    consistent use of online condition monitoring through active acoustic testing
    combined with complex pattern recognition for early crack detection in joined
    components has not yet been fully established. This research aims to develop an
    online crack detection system employing pattern recognition techniques under cyclic
    loading during fatigue tests, utilizing non-contact active acoustic testing with
    laser vibrometry. Due to the wide range of materials that can be joined, mechanical
    joining processes can be used in many different industry branches. Self-pierce
    riveting (SPR), in particular, is a well-established joining process. Therefore,
    the investigations for online crack detection initially focus on SPR joints. To
    achieve this, the fatigue behavior of SPR joints in a lap-shear configuration
    was characterized. Experimental fatigue testing demonstrated that SPR joint failure
    occurs either through cracks propagating in the sheet material away from the rivet
    or in the rivet foot, depending on the material combination. Laser vibrometry
    has been successfully used as a crack detection system and has proven to be effective
    in detecting crack initiation in SPR joints. Cracks can be detected without contact
    regardless of the material combination, the damage location, the size of the damage,
    or the type of damage.  The optimization of the crack detection system involved
    several key enhancements, including adjusting data acquisition to improve crack
    detection, incorporating principal component analysis (PCA) to reduce dimensionality,
    and implementing a classification model based on a global training dataset. An
    intuitive, problem-specific software demonstrator for analyzing the crack initiation
    behavior of SPR joints under cyclic loading was developed and iteratively optimized.
    Future work will focus on the implementation of an autoencoder network to further
    enhance crack detection capabilities.</jats:p>
