  text: <jats:p>Historical condition monitoring data from technical systems can be
    utilized to develop data-driven models for predicting the remaining useful life
    (RUL) of similar systems, whereas the Health Index (HI) often is a crucial component.
    The development of robust and accurate models requires meaningful features that
    reflect the system’s degradation process, enabling an accurate prediction of the
    system's HI. Traditionally, the identification of those is supported by one of
    various feature ranking methods. In literature, feature interdependencies and
    their transferability across various similar systems are not sufficiently considered
    in feature selection, exacerbating the challenge of HI prediction posed by the
    scarcity of data and system diversity in real-world applications. This work addresses
    this gaps by demonstrating how filter-based feature selection, incorporating failure
    thresholds and cross correlations, enhances feature selection leading to improved
    HI prediction. The proposed methodology is applied to a novel dataset* obtained
    from run-to-failure experiments on geared motors conducted as part of this study,
    which presents the aforementioned challenges. It is revealed that classical feature
    selection, consisting of feature ranking only, leaves potential untapped, which
    is utilized by the proposed selection methodology. It is shown that the proposed
    feature selection methodology leads to the best result with a RMSE of 0.14 in
    predicting the HI of a constructive different gearbox, while the features, determined
    by classical feature selection, lead to a RMSE of 0.19 at best.</jats:p>

  text: This paper investigates the remaining useful lifetime (RUL) estimation of
    bearings under dynamic, i.e., time-varying, operating conditions (OC). Unlike
    conventional studies that assume constant OC in bearing accelerated life tests,
    we introduce a dataset with time-varying OC during run-to-failure experiments,
    simulating real-world scenarios. We explore data-driven approaches to identify
    the transition point from a healthy to an unhealthy state and estimate the RUL.
    Additionally, we examine strategies for integrating OC information to enhance
    RUL estimations. These methodologies are evaluated through numerical experiments
    using various machine learning algorithms.

  text: This paper presents a comprehensive study on diagnosing a spacecraft propulsion
    system utilizing data provided by the Prognostics and Health Management (PHM)
    society, specifically obtained as part of the Asia-Pacific PHM conference’s data
    challenge 2023. The objective of the challenge is to identify and diagnose known
    faults as well as unknown anomalies in the spacecraft’s propulsion system, which
    is critical for ensuring the spacecraft’s proper functionality and safety. To
    address this challenge, the proposed method follows a systematic approach of feature
    extraction, feature selection, and model development. The models employed in this
    study are kMeans clustering and decision trees combined to ensembles, enriched
    with expert knowledge. With the method presented, our team was capable of reaching
    high accuracy in identifying anomalies as well as diagnosing faults, resulting
    in attaining the seventh place with a score of 93.08 %.

  text: "Ultraschall-Drahtbonden ist eine Standardtechnologie im Bereich der Aufbau-
    und Verbindungstechnik von Leistungshalbleitermodulen. Um Prozessschritte und
    damit wertvolle Zeit zu sparen, sollen die Kupferdickdrähte für die Leistungshalbleiter
    auch für die Kontaktierung von eingespritzten Anschlusssteckern im Modulrahmen
    verwendet werden. Das Kontaktierungsverfahren mit diesen Drähten auf Steckern
    in dünnwandigen Kunststoffrahmen führt häufig zu unzureichender Bondqualität.
    In dieser Arbeit wird das Bonden von Anschlusssteckern experimentell und anhand
    von Simulationen untersucht, um die Prozessstabilität zu steigern.\r\n\r\nZunächst
    wurden Experimente auf Untergründen mit hoher Steifigkeit durchgeführt, um Störgrößen
    von Untergrundeigenschaften zu verringern. Die gewonnenen Erkenntnisse erlaubten
    die Entwicklung eines Simulationsmodells für die Vorhersage der Bondqualität.
    Dieses basiert auf einer flächenaufgelösten Reibarbeitsbestimmung im Fügebereich
    unter Berücksichtigung des Ultraschallerweichungseffektes und der hierdurch entstehenden
    hohen Drahtverformung.\r\n\r\nExperimente an den Anschlusssteckern im Modulrahmen
    zeigten eine verringerte Relativverschiebung zwischen Draht und Stecker, was zu
    einer deutlichen Verringerung der Reibarbeit führt. Außerdem wurden verminderte
    Schwingamplituden des Bondwerkzeugs nachgewiesen. Dies führt zu einer weiteren
    Reduktion der Reibarbeit. Beide Effekte wurden mithilfe eines Mehrmassenschwingers
    modelliert. Die gewonnenen Erkenntnisse und die erstellten Simulationsmodelle
    ermöglichen die Entwicklung von Klemmvorrichtungen, welche die identifizierten
    Störgrößen gezielt kompensieren und so ein verlässliches Bonden der Anschlussstecker
    im gleichen Prozessschritt ermöglichen, in dem auch die Leistungshalbleiter kontaktiert
    werden."

  text: "Der Transport feiner Pulver mit in der Regel sehr hohen adhäsiven und kohäsiven
    Eigenschaften stellt für viele konventionelle Transportsysteme eine große Herausforderung
    dar. Durch die Anwendung von Ultraschallschwingungen können insbesondere die hohen
    adhäsiven Kontaktkräfte und damit auch die Reibungseigenschaften manipuliert werden.\r\n\r\nEin
    neu entwickeltes Pulvertransportsystem nutzt Ultraschallschwingungen, um die effektiven
    Tangentialkräfte im Pulver-Rohrkontakt zu reduzieren. Durch den koordinierten
    Einsatz von Ultraschallpulsen während einer niederfrequenten harmonischen Axialschwingung
    des Transportrohres wird ein kontinuierlicher Pulvertransport ermöglicht. Nach
    einer Einführung in die Grundlagen der Reibung und Reibungsmanipulation von Festkörpern
    und Pulvern sowie der Charakterisierung von Pulvern wird das Pulvertransportsystem
    auf Basis der Reibungsmanipulation inklusive der Leistungselektronik und der Ansteuerungshardware
    vorgestellt. Eine Sensitivitätsanalyse zeigt, dass die Anregungsparameter des
    Pulvertransportsystems ein großes Optimierungspotential aufweisen. Es wird ein
    effizientes, modulares Modell des Pulvertransportsystems vorgestellt, welches
    neben dem eigentlichen Modell des Transportprozesses ein Modell der Rohrschwingung
    und ein kennlinienbasiertes Modell des Pulver-Rohrkontakts beinhaltet. Mithilfe
    des Modells des Pulvertransportsystems werden Anregungsparameter hinsichtlich
    Amplituden und Frequenzen der auftretenden Schwingungen sowie der Schaltzeiten
    des Ultraschallpulses optimiert. "

  text: With enhancing digitalization, condition monitoring is used in an increasing
    number of application fields across various industrial sectors. By its application,
    increased reliability as well as reduced risks and costs can be achieved. Based
    on different approaches, technical systems are monitored and measured data is
    analyzed to enable condition-based or predictive maintenance. To this end, machine
    learning approaches are usually implemented to diagnose the health states or predict
    the health index of the monitored system. However, these trained models are often
    black-box models, not intuitively explainable for a human. To overcome this shortcoming,
    a model-based approach based on physics is developed for piezoelectric bending
    actuators. Such a model enables a transparent representation of the system. Moreover,
    the model-based approach is extended by a parameter-estimation to account for
    sudden changes in behavior e. g. caused by occurring cracks.

  text: Modelling of dynamic systems plays an important role in many engineering disciplines.
    Two different approaches are physical modelling and data‐driven modelling, both
    of which have their respective advantages and disadvantages. By combining these
    two approaches, hybrid models can be created in which the respective disadvantages
    are mitigated, with discrepancy models being a particular subclass. Here, the
    basic system behaviour is described physically, that is, in the form of differential
    equations. Inaccuracies resulting from insufficient modelling or numerics lead
    to a discrepancy between the measurements and the model, which can be compensated
    by a data‐driven error correction term. Since discrepancy methods still require
    a large amount of measurement data, this paper investigates the extent to which
    a single discrepancy model can be trained for a physical model with additional
    parameter dependencies without the need for retraining. As an example, a damped
    electromagnetic oscillating circuit is used. The physical model is realised by
    a differential equation describing the electric current, considering only inductance
    and capacitance; dissipation due to resistance is neglected. This creates a discrepancy
    between measurement and model, which is corrected by a data‐driven model. In the
    experiments, the inductance and the capacity are varied. It is found that the
    same data‐driven model can only be used if additional parametric dependencies
    in the data‐driven term are considered as well.

  text: Das Ultraschall-Dickdrahtbonden mit Aluminiumdraht ist ein Standardverfahren
    zur elektrischenKontaktierung von Leistungshalbleitermodulen. Die steigenden Anforderungen
    an die Effizienzund Zuverlässigkeit der Module haben zu technologischen Weiterentwicklungen
    geführt und eswerden vermehrt Kupferdrähte mit wesentlich besseren elektrischen
    und thermischen Eigenschafteneingesetzt. Hieraus resultieren durch höhere Prozesskräfte
    und Ultraschallleistung neueHerausforderungen bei der Prozessentwicklung; hierfür
    wird ein Simulationsmodell zur Verbesserungder Prozessentwicklung entwickelt.In
    Ultraschall-Drahtbondversuchen mit 400 m Aluminium und Kupfer Drähten wurde der
    Einflussder Prozessparameter auf die Bondqualität untersucht; diese Ergebnisse
    und zusätzliche Messungender Drahtdeformation und Schwingungen wurden für die
    Formulierung der Anforderungenund zur Validierung der Ergebnisse des Simulationsmodells
    genutzt.Es wurde ein Prozessmodell, basierend auf einer Co-Simulation zwischen
    MATLAB und ANSYS,entwickelt; hierbei wurden die phyiskalischen Phänomene wie die
    Ultraschall Werkstoffentfestigung,der Verbindungsaufbau und die dynamischen Systemeigenschaften
    abgebildet.Basierend auf einer Zug-Druck-Prüfmaschine wurde ein Prüfstand zur
    Identifikation der Modellparameterentwickelt. In zusätzlichen Druckversuchen mit
    den Bonddrähten mit und ohneUltraschallanregung wurde die Reduktion der Umformkräfte
    unter Ultraschalleinfluss untersucht.Mit dem entwickelten Prozessmodell wurden
    die Parameterstudien aus den Ultraschall-Drahtbondversuchensimuliert und direkt
    mit den experimentellen Ergebnissen verglichen, wobei sich einerelativ gute Übereinstimmung
    zwischen Simulation und Messung sowohl für Aluminium, als auchfür Kupfer, erzielen

  text: Ultrasonic heavy wire bonding with aluminium wire is a standard process to
    produce electricalcontacts in power semiconductor modules. The increasing demands
    on the efficiency and reliabilityof the modules have led to technological developments
    and copper wires with significantlybetter electrical and thermal properties are
    used more often nowadays. This results in new challengesin process development
    due to higher process forces and ultrasonic power; for this purpose,a simulation
    model is developed to improve process development.Ultrasonic wire bonding tests
    with 400 m aluminium and copper wires were carried out to investigatethe influence
    of the process parameters on the bond quality; these results and additionalmeasurements
    of wire deformation and vibrations were used to define the requirements for themodel
    and validate the results of the simulation.A process model based on a co-simulation
    was developed between MATLAB and ANSYS; thephysical phenomena such as ultrasonic
    softening of the wire material, bond formation and dynamicbehaviour of the components
    were considered.Based on a tensile-compression testing machine, a test rig was
    developed to identify the modelparameters. In additional compression tests with
    the wires with and without ultrasonic excitation,the reduction of the forming
    forces under ultrasonic influence was characterised.With the developed process
    model, the parameter studies from the ultrasonic wire bond testswere simulated
    and directly compared with the experimental results; a relative good agreementbetween
    simulation and measurement could be achieved for both aluminium and copper.

  text: Tire and road wear are a major source of emissions of nonexhaust particulate
    matter (PM) and make up the largest share of microplastics in the environment.
    To reduce tire wear through numerical optimization of a vehicle's suspension system,
    fast simulations of the representative usage of a vehicle are needed. Therefore,
    this contribution evaluates if instead of a full simulation of a representative
    test drive, only specific driving maneuvers resulting from a clustering of the
    driving data can be used to predict tire wear. As a measure for tire wear, the
    friction work between tire and road is calculated. It is shown that enough clusters
    result in negligible deviations between the total friction work of the full simulation
    and the cluster simulations as well as between the distributions of the friction
    work over the tire width. The calculation time can be reduced to about 1% of the
    full simulation.

  text: 'This article is dedicated to piezoelectric ultrasonic power transducers that
    differ to well known medical ultrasonic diagnostic apparatus or non destructive
    testing devices by the level of power in use; typically several tens of up to
    more than thousand watts are used in a multitude of different applications. After
    a short introduction including historical development, the first focus is on theoretical
    background of the operating principle, design and mechanical modeling. As piezoelectric
    elements transform electrical to mechanical energy and vice versa, equivalent
    circuit modeling is also described. After that, sample applications are delineated
    by the matter wherein ultrasound generates unique effects: incredible high pressure
    level as well in air as in water, micro-bubbles generating temperature peaks for
    very short time instances in fluids, acoustoplastic effect, enhancement of diffusion
    and recrystallization in solids, friction manipulation, incremental deformation
    and micro-cracking of surfaces, or even generation of macroscopic movements in
    motors. At the end, some future directions ranging from novel modeling approaches
    to advanced control and new materials are addressed.'

  text: "To achieve optimum bond results at ultrasonic bonding thick copper wire on
    sensitive components is quite challenging.\r\nBearing in mind that high normal
    force and ultrasonic power are needed for bond quality but as well increase stress
    and finally failure risk of the substrate, methods should be found to achieve
    high bond quality even at lower bond parameters. Therefore, bond experiments with
    different bond tool grove geometries have been conducted for copper and aluminum
    wire on direct copper bonded (DCB) substrates to investigate the impact of geometric
    parameters on bond formation and bond quality. The wire material depending impact
    of geometry changes on the bond formation and deformation was quantified. Additionally,
    a bonding parameter design of experiments (DOE) has been conducted for the reference
    and the most promising groove geometry. Higher shear values were achieved at reduced
    vertical tool displacement for most bonding parameter combinations, compared to
    the reference tool. This behavior allows for reducing ultrasonic power to obtain
    equal shear values; consequently, mechanical stresses in the interface decrease.
    This could potentially reduce the risk of chip damage and thus yield loss."

  text: 'ue to the constantly growing energy demand of power electronics and the need
    to reduce the size of electronic components like power modules for e-mobility,
    new challenges arise for ultrasonic wire bonding: the electrical connection must
    endure higher thermal and mechanical stress while the connecting partners become
    more sensitive or require more energy to get bonded. Past investigations have
    shown already that multi-dimensional ultrasonic bonding and welding yield the
    same or even better bond quality while reducing the load on the components. This
    contribution is intended to show whether multidi-mensional thick wire bonding
    is a promising concept to over-come the new challenges. The focus is on experimental
    investi-gations of different bond tool trajectories in ultrasonic wire bonding
    of aluminum and copper wire on DCB''s and chips. The bond quality is analyzed
    by shear tests, microsections and, in the case of aluminum bonding, by a new machine
    learning method for an objective automated evaluation of the sheared area.'
