  text: This study presents a numerical approach using a 3D finite element model to
    quantify the remaining clamp load of a plastic nut joint after a specific time.
    The viscoelastic relaxation of a thermoplastic nut, which is predominantly screwed
    on a welding stud, is described by a material card using Prony Series. Prony Series
    are derived from experimental Dynamical Mechanical Analysis with different moisture
    and fiber contents of the thermoplastic. Since plastic nuts usually do not have
    preformed threads, the increased temperatures and resulting stresses from the
    thread-forming process are considered in the simulation. Firstly, the FE model
    is verified by substrate stress relaxation tests. Subsequently, experimental clamp
    load measurements with miniature compression load cells verify the clamp load
    prediction. Finally, the developed model is used to analyze the clamp load distribution
    within the threads

  text: Die Inbetriebnahme von Steuerungen und Regelungen stellt sicher, dass ein
    mechatronisches System ordnungsgemäß funktioniert und den Anforderungen gerecht
    wird. Der modellbasierte Entwurf basiert auf einem genauen Simulationsmodell.
    Allerdings ist dieser klassische Weg bei komplexen Systemen oft nicht praktikabel,
    da die analytische Modellierung zu kompliziert und zeitaufwendig ist. Diese Forschungslücke
    wird durch Verfahren adressiert, die eine effiziente und sichere Inbetriebnahme
    ermöglichen. Diese Verfahren kombinieren Regelungstechnik und Reinforcement Learning
    und nutzen vorhandenes Wissen über die Regelungsaufgabe, um Korrekturen basierend
    auf Messdaten und der probabilistischen Gauß-Prozess-Regression vorzunehmen. Das
    Vorwissen kann als teilweise bekanntes physikalisches Modell oder als Steuerungsfunktion
    vorliegen. Anwendungsbeispiele sind der Ultraschalldrahtbondprozess, verschiedene
    Pendelsysteme und ein Hexapod. Eine angepasste Bayessche Optimierung wird zur
    Identifikation einer Steuerparametrisierung für das Ultraschallbonden eingesetzt.
    Außerdem wird eine hybride Optimalsteuerung für das Doppelpendel auf einem Wagen
    entwickelt und erfolgreich validiert. Fur einen Hexapod zur Fahrzeugachsprüfung
    wird eine hybride Zustandslinearisierung formuliert und ein Funktionsnachweis
    im Rahmen einer Simulation erbracht. Die Einhaltung technischer Rahmenbedingungen
    und stabiles Systemverhalten werden durch probabilistische Pradiktionen gewährleistet.
    In allen Anwendungsfällen wird eine Steigerung der Effizienz und Güte erzielt.

  text: The commissioning of control systems ensures that a mechatronic system functions
    properly and meets the requirements. Model-based design is based on a precise
    simulation model. However, this classic approach is often impractical for complex
    systems, as analytical modeling is too complicated and time-consuming. This research
    gap is addressed by methods that enable efficient and safe commissioning. These
    methods combine control engineering and reinforcement learning and use existing
    knowledge about the control task to make corrections based on measurement data
    and probabilistic Gaussian process regression. The prior knowledge can be available
    as a partially known physical model or as a control function. Application examples
    include the ultrasonic wire bonding process, various pendulum systems and a hexapod.
    An adapted Bayesian optimization is used to identify a control parameterization
    for ultrasonic bonding. In addition, a hybrid optimal control for the double pendulum
    on a cart is developed and successfully validated. A hybrid state linearization
    is formulated for a hexapod for vehicle axle testing and a proof of concept is
    provided in a simulation. Compliance with technical framework conditions and stable
    system behavior are ensured by probabilistic predictions. An increase in efficiency
    and quality is achieved in all use cases.

  text: <jats:p>Similar to bulk metal forming, clinch joining is characterised by
    large plastic deformations and a variety of different 3D stress states, including
    severe compression. However, inherent to plastic forming is the nucleation and
    growth of defects, whose detrimental effects on the material behaviour can be
    described by continuum damage models and eventually lead to material failure.
    As the damage evolution strongly depends on the stress state, a stress-state-dependent
    model is utilised to correctly track the accumulation. To formulate and parameterise
    this model, besides classical experiments, so-called modified punch tests are
    also integrated herein to enhance the calibration of the failure model by capturing
    a larger range of stress states and metal-forming-specific loading conditions.
    Moreover, when highly ductile materials are considered, such as the dual-phase
    steel HCT590X and the aluminium alloy EN AW-6014 T4 investigated here, strong
    necking and localisation might occur prior to fracture. This can alter the stress
    state and affect the actual strain at failure. This influence is captured by coupling
    plasticity and damage to incorporate the damage-induced softening effect. Its
    relative importance is shown by conducting inverse parameter identifications to
    determine damage and failure parameters for both mentioned ductile metals based
    on up to 12 different experiments.</jats:p>

  text: Batch and process fluctuations during the fabrication of sheet metal components
    result in discrepancies in the resulting component properties, affecting subsequent
    process steps and potentially leading to production rejects. Consequently, the
    identification of deviations and knowledge of the effects of fluctuations are
    crucial for achieving consistently high product quality, reducing waste and thus
    increasing resource efficiency of production processes through countermeasures
    derived from this. The approach presented to address this is the use of data-driven
    metamodeling to map entire process chains and predict process parameters in order
    to compensate for process and batch fluctuation. The investigated process chain
    consists of the sub-processes deep drawing, clamping and clinching. For each process
    step, relevant input and output variables are identified, numerical simulation
    models are created, and subsequently validated. Variant simulations of the sub-processes
    are conducted and evaluated to generate a database for the metamodeling of the
    individual process steps. Machine learning techniques are utilized for the automated
    selection and optimization of learning methods to create models that depict the
    relationships between input and output variables. Finally, the models for the
    sub-processes are linked together to form a superordinate metamodel for the entire
    process chain, with the aim to make inline-process adaptations possible.<br

  text: Within the current energy and environmental crisis, new material- and energy-saving
    processes are needed. For this reason, this study focuses on the development of
    a new forming technology for Ti-6Al-4V sheet metal. It is based on combination
    of solution treatment by resistive heating with rapid tool-based quenching and
    subsequent annealing. This new “TISTRAQ” process is comparable with press-hardening
    already known for steels and hot die quenching known for aluminium alloys. One
    of the main influencing factors for this process is the heat transfer coefficient
    (HTC). It is an important driver for adjustment of basic parameters, as selection
    of tool material or the forming speed but also plays an important role while elaborating
    temperature distribution in the numerical model. Therefore, a new and unique test
    rig was developed to determine the HTC and to perform tool-based heat treatment
    at specimen level under laboratory conditions. The test rig was used to investigate
    the influence of the titanium-tool-lubricant system on HTC and cooling rate. Further
    the effect of heat treatment in the test rig and tool-based quenching on microstructure
    and mechanical properties was studied. To improve the prediction of the temperature
    distribution of the titanium during cooling, the HTC was integrated into the numerical
    process simulation

    \               <jats:p>Cardiopulmonary exercise testing (CPET) is considered
    the gold standard for assessing cardiorespiratory fitness. To ensure consistent
    performance of each test, it is necessary to adapt the power increase of the test
    protocol to the physical characteristics of each individual. This study aimed
    to use machine learning models to determine individualized ramp protocols based
    on non-exercise features. We hypothesized that machine learning models will predict
    peak oxygen uptake (<jats:inline-formula><jats:alternatives><jats:tex-math>$$\\dot{V}$$</jats:tex-math><mml:math

  text: '<jats:title>Abstract</jats:title><jats:sec><jats:title>Aim</jats:title><jats:p>To
    investigate the associations of the Dietary Approaches to Stop Hypertension (DASH)
    score with subcutaneous (SAT) and visceral (VAT) adipose tissue volume and hepatic
    lipid content (HLC) in people with diabetes and to examine whether changes in
    the DASH diet were associated with changes in these outcomes.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>In
    total, 335 participants with recent‐onset type 1 diabetes (T1D) and type 2 diabetes
    (T2D) from the German Diabetes Study were included in the cross‐sectional analysis,
    and 111 participants in the analysis of changes during the 5‐year follow‐up. Associations
    between the DASH score and VAT, SAT and HLC and their changes were investigated
    using multivariable linear regression models by diabetes type. The proportion
    mediated by changes in potential mediators was determined using mediation analysis.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>A
    higher baseline DASH score was associated with lower HLC, especially in people
    with T2D (per 5 points: −1.5% [−2.7%; −0.3%]). Over 5 years, a 5‐point increase
    in the DASH score was associated with decreased VAT in people with T2D (−514 [−800;
    −228] cm<jats:sup>3</jats:sup>). Similar, but imprecise, associations were observed
    for VAT changes in people with T1D (−403 [−861; 55] cm<jats:sup>3</jats:sup>)
    and for HLC in people with T2D (−1.3% [−2.8%; 0.3%]). Body mass index and waist
    circumference changes explained 8%‐48% of the associations between DASH and VAT
    changes in both groups. In people with T2D, adipose tissue insulin resistance
    index (Adipo‐IR) changes explained 47% of the association between DASH and HLC
    changes.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>A
    shift to a DASH‐like diet was associated with favourable VAT and HLC changes,
    which were partly explained by changes in anthropometric measures and Adipo‐IR.</jats:p></jats:sec>'

  text: <jats:p> A numerical modelling strategy for the direct pin pressing process
    of metallic pins into continuous fibre-reinforced thermoplastic organosheets is
    developed. The joining process is performed above the thermoplast’s melting temperature,
    altering the initial material structure of the composite by fibre rearrangement,
    which in turn influences the load-bearing capacity of the joint. Therefore, the
    modelling strategy aims at predicting the resultant material structure after pin
    pressing. The modelling approach considers both the textile architecture and the
    process parameters (temperature, tool velocity). A sub-meso modelling framework
    for the fibres based on a multi-filament approach is used. The interaction between
    fibres and the thermoplastic melt, as well as the matrix flow, is modelled using
    the Arbitrary Lagrangian Eulerian method. This allows for the prediction of matrix-rich
    zones and fibre rearrangement around the pin. The promising results show a good
    agreement of the resultant material structure in terms of compaction and fibre
    volume content around the pressed pin. Characteristic parameters show an underestimation
    of the laminate thickness below the pin. Moreover, an evaluation method for evaluating
    the orientation changes of the virtual multi-filaments is developed and presented
    to observe and assess fibre rearrangement and fibre volume content in detail during
    the numerical process simulation. It can be seen that only fibres around the pin
    are displaced and not in the whole molten area. Furthermore, it can be observed
    in detail that the initial position of the fibres in relation to the pin determines
    whether the fibres are displaced in the in-plane or out-of-plane direction. </jats:p>

  text: <jats:p>Abstract. Traditionally, joints are cylindrical and rotationally symmetric.
    In the present study, non-rotationally symmetric joints are used for joining steel
    and Glass mat-reinforced thermoplastic sheets (GMT). In addition, the study also
    analyzes the impact of non-rotational symmetric joint rotation on the load-bearing
    capacity. Single lap joint specimens were fabricated using the In-Mold assembly
    technique for joining steel sheets with GMT. Tensile shear tests were performed
    on different orientations of the joint geometry, and it was observed that changing
    the joint orientation influences the load-bearing capacity. The joints are constitutively
    modeled using beam elements and the influence of joint rotation on load distribution
    is examined through a static simulation study. </jats:p>

  text: <jats:p>Simulation models are used to design extruders in the polymer processing
    industry. This eliminates the need for prototypes and reduces development time
    for extruders and, in particular, extrusion screws. These programs simulate, among
    other process parameters, the temperature and pressure curves in the extruder.
    At present, it is not possible to predict the resulting melt quality from these
    results. This paper presents a simulation model for predicting the melt quality
    in the extrusion process. Previous work has shown correlations between material
    and thermal homogeneity and the screw performance index. As a result, the screw
    performance index can be used as a target value for the model to be developed.
    The results of the simulations were used as input variables, and with the help
    of artificial intelligence—more precisely, machine learning—a linear regression
    model was built. Finally, the correlation between the process parameters and the
    melt quality was determined, and the quality of the model was evaluated.</jats:p>

  text: 'This study investigates the potential of using advanced conversational artificial
    intelligence (AI) to help people understand complex AI systems. In line with conversation-analytic
    research, we view the participatory role of AI as dynamically unfolding in a situation
    rather than being predetermined by its architecture. To study user sensemaking
    of intransparent AI systems, we set up a naturalistic encounter between human
    participants and two AI systems developed in-house: a reinforcement learning simulation
    and a GPT-4-based explainer chatbot. Our results reveal that an explainer-AI only
    truly functions as such when participants actively engage with it as a co-constructive
    agent. Both the interface’s spatial configuration and the asynchronous temporal
    nature of the explainer AI – combined with the users’ presuppositions about its
    role – contribute to the decision whether to treat the AI as a dialogical co-participant
    in the interaction. Participants establish evidentiality conventions and sensemaking
    procedures that may diverge from a system’s intended design or function.'
