  text: 'In order to reduce the fuel consumption and consequently the greenhouse emissions,
    the automotive industry is implementing lightweight constructions in the body
    in white production. As a result, the use of aluminum alloys is continuously increasing.
    Due to poor weldability of aluminum in combination with other materials, mechanical
    joining technologies like clinching are increasingly used. In order to predict
    relevant characteristics of clinched joints and to ensure the reliability of the
    process, it is simulated numerically during product development processes. In
    this regard the predictive accuracy of the simulated process highly depends on
    the implemented friction model. In particular, the frictional behavior between
    the sheet metals affects the geometrical formation of the clinched joint significantly.
    This paper presents a testing method, which enables to determine the frictional
    coefficients between sheet metal materials for the simulation of clinching processes.
    For this purpose, the correlation of interface pressure and the relative velocity
    between aluminum sheets in clinching processes is investigated using numerical
    simulation. Furthermore, the developed testing method focuses on the specimen
    geometry as well as the reproduction of the occurring friction conditions between
    two sheet metal materials in clinching processes. Based on a methodical approach
    the test setup is explained and the functionality of the method is proven by experimental
    tests using sheet metal material EN AW6014. '

  text: Ultrasonic wire bonding is a solid-state joining process, used in the electronics
    industry to form electrical connections, e.g. to connect electrical terminals
    within semiconductor modules. Many process parameters affect the bond strength,
    such like the bond normal force, ultrasonic power, wire material and bonding frequency.
    Today, process design, development, and optimization is most likely based on the
    knowledge of process engineers and is mainly performed by experimental testing.
    In this contribution, a newly developed simulation tool is presented, to reduce
    time and costs and efficiently determine optimized process parameter. Based on
    a co-simulation of MATLAB and ANSYS, the different physical phenomena of the wire
    bonding process are considered using finite element simulation for the complex
    plastic deformation of the wire and reduced order models for the transient dynamics
    of the transducer, wire, substrate and bond formation. The model parameters such
    as the coefficients of friction between bond tool and wire and between wire and
    substrate were determined for aluminium and copper wire in experiments with a
    test rig specially developed for the requirements of heavy wire bonding. To reduce
    simulation time, for the finite element simulation a restart analysis and high
    performance computing is utilized. Detailed analysis of the bond formation showed,
    that the normal pressure distribution in the contact between wire and substrate
    has high impact on bond formation and distribution of welded areas in the contact
    area.

  text: As an effective and accurate method for modelling composite materials, mean-field
    homogenization is still not well studied in modelling non-linear and damage behaviours
    of UD composites. Investigated micro FE-simulations show that the matrix of UD
    composites exhibits different average plastic behaviour, named as average asymmetric
    matrix plasticity (AAMP), when the composite behaves different under shear, longitudinal
    and transverse loadings. In this study, a non-linear mean-field debonding model
    (NMFDM) combining a mean-field model and a fibre–matrix interface debonding model,
    is developed to simulate UD composites under consideration of AAMP, fibre–matrix
    interface damage and progressive failure. AAMP is considered by using so-called
    stress mode factor, which is expressed in terms of basic invariants of the matrix
    deviatoric stress tensor and is used as an indicator for detection of differences
    in the loading mode. The material behaviour of UD composites with imperfect interface
    is assumed identical as for perfect interface and stiffness reduced fibres. Progressive
    failure criteria are established with consideration of fibre breakage and matrix
    crack for different fibre orientations. As a representative example for the NMFDM,
    a C30/E201 UD composite is studied. To verify the model, experiments are conducted
    on polymers, carbon fibres and UD CFRPs. Finally, the model is applied to simulate
    a perforated CFRP laminate, which shows excellent prediction ability on deformation,
    debonding and progressive failure.

  text: "The online fitting of a microscopic traffic simulation model to reconstruct
    the current state of a real traffic\r\narea can be challenging depending on the
    provided data. This paper presents a novel method based on limited\r\ndata from
    sensors positioned at specific locations and guarantees a general accordance of
    reality and\r\nsimulation in terms of multimodal road traffic counts and vehicle
    speeds. In these considerations, the actual\r\npurpose of research is of particular
    importance. Here, the research aims at improving the traffic flow by\r\ncontrolling
    the Traffic Light Systems (TLS) of the examined area which is why the current
    traffic state and\r\nthe route choices of individual road users are the matter
    of interest. An integer optimization problem is derived\r\nto fit the current
    simulation to the latest field measurements. The concept can be transferred to
    any road traffic\r\nnetwork and results in an observation of the current multimodal
    traffic state matching at the given sensor\r\nposition. First case studies show
    promosing results in terms of deviations between reality and simulation."

  text: Using near-field (NF) scan data to predict the far-field (FF) behaviour of
    radiating electronic systems represents a novel method to accompany the whole
    RF design process. This approach involves so-called Huygens' box as an efficient
    radiation model inside an electromagnetic (EM) simulation tool and then transforms
    the scanned NF measured data into the FF. For this, the basic idea of the Huygens'box
    principle and the NF-to-FF transformation are briefly presented. The NF is measured
    on the Huygens' box around a device under test using anNF scanner, recording the
    magnitude and phase of the site-related magnetic and electric components. A comparison
    between a fullwave simulation and the measurement results shows a good similarity
    in both the NF and the simulated and transformed FF.Thus, this method is applicable
    to predict the FF behaviour of any electronic system by measuring the NF. With
    this knowledge, the RF design can be improved due to allowing a significant reduction
    of EM compatibility failure at the end of the development flow. In addition, the
    very efficient FF radiation model can be used for detailed investigations in various
    environments and the impact of such an equivalent radiation source on other electronic
    systems can be assessed.

  text: "Due to the strong reduction of PV prices, storage plays a dominating role
    in overall system costs. A \r\nsteeper elevation angle would result in a more
    balanced seasonal PV yield, at the cost of PV yield reductions during \r\nsummer,
    but allowing reduced storage capacities. Additionally, the effect of a single-axis
    tracking system has been \r\ninvestigated, generating more electricity during
    the morning and evening hours, thus reducing daily storage \r\nrequirements. The
    necessary PV size and storage capacities required for the German energy supply
    (1,500 TWh after \r\nelectrification of all sectors) via 100% renewable energies
    and a 50% solar share have been calculated via the \r\nHOMER Pro software, considering
    the bridging of periods of \"dark lulls“ in winter, using costs of 2030 (Table
    1). \r\nResults: The increase of module elevation angles above the typical 30°
    leads to a reduction of investment and supply \r\ncosts. The optimum is reached
    at a cost reduction of -1.5% for an elevation angle at the latitude of the installation
    \r\nsite. An explanation is that high elevation angles are favorable for clear
    winter days, but not at all for the critical days \r\nwith diffuse irradiance
    only, so the battery capacity must be increased. For the same reason, tracking
    systems do not \r\noffer any cost advantage (at least for the ones without an
    option for horizontal positioning during diffuse days)."

  text: Dynamical systems often admit geometric properties that must be taken into
    account when studying their behavior. We show that many such properties can be
    encoded by means of quiver representations. These properties include classical
    symmetry, hidden symmetry, and feedforward structure, as well as subnetwork and
    quotient relations in network dynamical systems. A quiver equivariant dynamical
    system consists of a collection of dynamical systems with maps between them that
    send solutions to solutions. We prove that such quiver structures are preserved
    under Lyapunov--Schmidt reduction, center manifold reduction, and normal form
    reduction.

  text: "Artificial intelligence (AI) has the potential for far-reaching – in our
    opinion – irreversible changes.\r\nThey range from effects on the individual and
    society to new societal and social issues. The question arises\r\nas to how students
    can learn the basic functioning of AI systems, what areas of life and society
    are affected\r\nby these and – most important – how their own lives are affected
    by these changes. Therefore, we are developing and evaluating school materials
    for the German ”Science Year AI”. It can be used for students of all\r\nschool
    types from the seventh grade upwards and will be distributed to about 2000 schools
    in autumn with\r\nthe support of the Federal Ministry of Education and Research.
    The material deals with the following aspects\r\nof AI: Discussing everyday experiences
    with AI, how does machine learning work, historical development\r\nof AI concepts,
    difference between man and machine, future distribution of roles between man and
    machine,\r\nin which AI world do we want to live and how much AI would we like
    to have in our lives. Through an\r\naccompanying evaluation, high quality of the
    technical content and didactic preparation is achieved in order\r\nto guarantee
    the long-term applicability in the teaching context in the different age groups
    and school types.\r\nIn this paper, we describe the current state of the material
    development, the challenges arising, and the results\r\nof tests with different
    classes to date. We also present first ideas for evaluating the results."

  text: Das Nasspressverfahren ist ein Serienherstellungsprozess für Bauteile aus
    duroplastischen Faserverbundkunststoffen (FVK) mit einer geringen Geometriekomplexität.
    Im Rahmen dieser Arbeit wurde ein modiﬁziertes Nasspressverfahren untersucht,
    welches die Herstellung von hybriden Blech-FVK-Strukturen ermöglicht. Die stoffschlüssige
    Verbindung zwischen dem metallischen Trägerbauteil und einem lokalen FVK-Verstärkungselement
    wird durch Co-Bonding im Nasspresswerkzeug aufgebaut. Epoxidbasierte Matrixharze
    und Klebstoffe wurden mit Methoden der Klebtechnik sowie thermischen und rheometrischen
    Prüfungen charakterisiert, um ein materialspeziﬁsches Fertigungsprozessfenster
    einzugrenzen. Experimentelle Untersuchungen zum Nasspressen von GFK-Laminaten
    und Stahl-GFK-Hybridstrukturen fokussierten die Mikrostruktur und das strukturelle
    Verhalten von stoffschlüssigen Hybridverbindungen. Unter anderem wurden Einﬂüsse
    von zeit-, temperatur- und druckabhängigen Fertigungsparametern sowie der Einsatz
    von Strukturklebstoffﬁlmen und internen Trennmitteln analysiert. Anhand von Fallturmtests
    an hybriden Demonstratorkomponenten konnte das modiﬁzierte Nasspressverfahren
    für die Herstellung crashrelevanter Karosseriebauteile qualiﬁziert werden.

  text: Ultraschall wird zur Effizienzsteigerung in verfahrenstechnischen Prozessen
    eingesetzt. Die Betriebsparamter der Ultraschallsysteme werden empirisch ermittelt,
    da derzeit keine systematische Analyse der Wechselwirkung zwischen Ultraschallwandler
    und Schallfeld sowie kein Verfahren zur Messung der Kavitationsaktivität ohne
    zusätzlichen Sensor existieren. Auf Basis einer experimentellen Analyse des betrachteten
    sonochemischen Reaktors wird ein Finite-Elemente-Modell aufgebaut, das die Wechselwirkung
    zwischen Schallfeld und Ultraschallwandler berücksichtigt. Die modellbasierte
    Analyse zeigt, dass wegen der akustischen Eigenschaften des Autoklavs nur direkt
    an der Sonotrode Kavitation entsteht. Die Wechselwirkung zwischen Ultraschallwandler
    und Schallfeld ermöglicht Aussagen über das Schallfeld und die Kavitationsaktivität
    auf Basis der Rückwirkung auf den Ultraschallwandler. Die lineare Schalldruckverteilung
    ermöglicht eine Prognose über die Verteilung von Kavitationszonen. Das beschriebene
    Modell liefert wertvolle Erkenntnisse für die Auslegung, Analyse und Skalierung
    sonochemischer Reaktoren. Auf Grund der rauen Prozessrandbedingungen ist die Applikation
    von Sensoren zur Überwachung der Kavitationsaktivität in vielen sonochemischen
    Prozessen nicht möglich. Zur prozessbegleitenden Messung der Kavitationsaktivität
    wird ein Verfahren entwickelt, das die Bewertung der Kavitationsaktivität durch
    Auswertung der Rückwirkung auf den Ultraschallwandler erlaubt. Das Messverfahren
    ermöglicht eine vorhersagbare und reproduzierbare Durchführung kavitationsbasierter
    Prozesse und stellt eine wichtige Erweiterung für bestehende und neue Ultraschallsysteme
    dar.

  text: CO oxidation is an extensively studied reaction in heterogeneous catalysis
    due to its seeming simplicity and its great importance for emission control. However,
    the role of particle size and more specifically structure sensitivity in this
    reaction is still controversial. In the present study, colloidal “surfactant-free”
    Pt nanoparticles (NPs) in a size regime of 1–4 nm with narrow size distribution
    and control over particle size were synthesized and subsequently supported on
    Al2O3 to prepare model catalysts. CO oxidation was performed using Pt NPs catalysts
    with particles sizes of 1, 2, 3, and 4 nm at different reaction temperatures.
    It is shown that the reaction exhibits a particle size effect that depends strongly
    on the reaction conditions. At 170 °C, the reaction seems to proceed within the
    same kinetic regime for all particle sizes, but the surface normalized activity
    depends strongly on the particle size, with maximum activity for nanoparticles
    2 nm in diameter. A temperature increase to 200 °C leads to a change of the kinetic
    regime that depends on the particle size. For Pt NPs 1 nm in diameter a reaction
    order of 1 for O2 was observed, indicating that O2 adsorbs molecularly and dissociates
    in a following step, which represents the generally accepted mechanism on Pt surfaces.
    The reaction order of −1 for CO demonstrates that the surface is saturated with
    CO under reaction conditions. With increasing particle size, the reaction orders
    of O2 and CO change. For particles 2 nm in size, an increase in temperature also
    results in reaction orders of 1 for O2 and −1 for CO; NPs of 3 and 4 nm, even
    at higher temperatures, show no clear kinetic behavior that can be explained by
    a single reaction mechanism. Instead, the Boudouard reaction between two adjacent
    adsorbed CO molecules was identified as an important additional reaction pathway
    that occurs preferentially on large particles and causes more complex kinetics.

  text: "Approximate computing has become a very popular design\r\nstrategy that exploits
    error resilient computations to achieve higher\r\nperformance and energy efﬁciency.
    Automated synthesis of approximate\r\ncircuits is performed via functional approximation,
    in which various\r\nparts of the target circuit are extensively examined with
    a library\r\nof approximate components/transformations to trade off the functional\r\naccuracy
    and computational budget (i.e., power). However, as the number\r\nof possible
    approximate transformations increases, traditional search\r\ntechniques suffer
    from a combinatorial explosion due to the large\r\nbranching factor. In this work,
    we present a comprehensive framework\r\nfor automated synthesis of approximate
    circuits from either structural\r\nor behavioral descriptions. We adapt the Monte
    Carlo Tree Search\r\n(MCTS), as a stochastic search technique, to deal with the
    large design\r\nspace exploration, which enables a broader range of potential
    possible\r\napproximations through lightweight random simulations. The proposed\r\nframework
    is able to recognize the design Pareto set even with low\r\ncomputational budgets.
    Experimental results highlight the capabilities of\r\nthe proposed synthesis framework
    by resulting in up to 61.69% energy\r\nsaving while maintaining the predeﬁned
    quality constraints."

- lang: eng
  text: 'This study proposes a simple theoretical framework that allows for assessing
    financial distress up to five years in advance. We jointly model financial distress
    by using two of its key driving factors: declining cash-generating ability and
    insufficient liquidity reserves. The model is based on stochastic processes and
    incorporates firm-level and industry-sector developments. A large-scale empirical
    implementation for US-listed firms over the period of 1980-2010 shows important
    improvements in the discriminatory accuracy and demonstrates incremental information
    content beyond state-of-the-art accounting and market-based prediction models.
    Consequently, this study might provide important ex ante warning signals for investors,
    regulators and practitioners.'
