  text: "The first order optimality conditions of optimal control problems (OCPs)
    can\r\nbe regarded as boundary value problems for Hamiltonian systems. Variational
    or\r\nsymplectic discretisation methods are classically known for their excellent\r\nlong
    term behaviour. As boundary value problems are posed on intervals of\r\nfixed,
    moderate length, it is not immediately clear whether methods can profit\r\nfrom
    structure preservation in this context. When parameters are present,\r\nsolutions
    can undergo bifurcations, for instance, two solutions can merge and\r\nannihilate
    one another as parameters are varied. We will show that generic\r\nbifurcations
    of an OCP are preserved under discretisation when the OCP is\r\neither directly
    discretised to a discrete OCP (direct method) or translated\r\ninto a Hamiltonian
    boundary value problem using first order necessary\r\nconditions of optimality
    which is then solved using a symplectic integrator\r\n(indirect method). Moreover,
    certain bifurcations break when a non-symplectic\r\nscheme is used. The general
    phenomenon is illustrated on the example of a cut\r\nlocus of an ellipsoid."

  text: Phase-shift modulated full bridge converters suffer from thermal imbalances
    of the inverter switches. The lagging leg switches are subject to larger commutation
    currents compared to those of the leading leg as the transformer current reduces
    in the freewheeling interval. Furthermore, after this interval, the energy in
    the series inductance may not be large enough to achieve zero-voltage switching
    (ZVS) for the leading leg. Both effects result in thermal imbalances. This paper
    analyzes the alternating-asymmetrical phase-shift modulation to achieve balanced
    conduction and switching losses for all four switches while showing that this
    modulation is easily implemented on standard DSPs. The modulation has been implemented
    to LLC converters where experimental measurement results proved its effectiveness
    for LLC converters by reducing the temperature deviation from 6.3 K to only 0.2
    K such that the peak temperature is reduced from 95 °C to 92 °C. The paper also
    proves that the modulation can be utilized to improve the efficiency of LLC converters
    operated at very low gains while simultaneously reducing the junction temperature
    of all four switches compared to the conventional complementary modulation. Finally,
    EMI implications are analyzed, which show that the modulation may be beneficial
    for reducing the common-mode emissions around the operating frequency.

  text: LLC resonant converters are typically unsuitable to be applied for wide voltage-transfer
    ratio applications. With a full-bridge inverter, however, they can be operated
    in a variety of different modulations. Most notably, by permanently turning on
    one MOSFET and turning off the other MOSFET of the same bridge leg, the LLC can
    be operated in half-bridge configuration reducing the gain by a factor of two.
    The resonant capacitor is hereby charged to an average voltage of half the input
    voltage. In this modulation, however, the switch that is permanently turned on
    is stressed by the complete resonant current while exhibiting no switching losses.
    This paper proves that the frequency-doubler modulation can better balance the
    losses among all MOSFETs and should be the preferred mode of operation favored
    over the conventional half-bridge modulation. This paper analyzes the beneficial
    loss distribution, proposes an on-the-fly morphing modulation and discusses potential
    operating strategies to further reduce the junction temperature. Furthermore,
    it is shown that this modulation can also be altered to achieve the asymmetrical
    LLC operation. Experimental measurement results show that the modulation results
    in a substantial decrease of the maximum MOSFET temperature and shows that the
    converter can be smoothly transitioned during operation from full-bridge modulation
    to the frequency-doubler half-bridge operation and back.

  text: One of the main objectives of production engineering is to reproducibly manufacture
    (complex) defect-free parts. To achieve this, it is necessary to employ an appropriate
    process or tool design. While this will generally prove successful, it cannot,
    however, offset stochastic defects with local variations in material properties.
    Closed-loop process control represents a promising approach for a solution in
    this context. The state of the art involves using this approach to control geometric
    parameters such as a length. So far, no research or applications have been conducted
    with closed-loop control for microstructure and product properties. In the project
    on which this paper is based, the local martensite content of parts is to be adjusted
    in a highly precise and reproducible manner. The forming process employed is a
    special, property-controlled flow-forming process. A model-based controller is
    thus to generate corresponding correction values for the tool-path geometry and
    tool-path velocity on the basis of online martensite content measurements. For
    the controller model, it is planned to use a special process or microstructure
    (correlation) model. The planned paper not only describes the experimental setup
    but also presents results of initial experimental investigations for subsequent
    use in the closed-loop control of α’-martensite content during flow-forming.

  text: In the industry 4.0 era, there is a growing need to transform unstructured
    data acquired by a multitude of sources into information and subsequently into
    knowledge to improve the quality of manufactured products, to boost production,
    for predictive maintenance, etc. Data-driven approaches, such as machine learning
    techniques, are typically employed to model the underlying relationship from data.
    However, an increase in model accuracy with state-of-the-art methods, such as
    deep convolutional neural networks, results in less interpretability and transparency.
    Due to the ease of implementation, interpretation and transparency to both domain
    experts and non-experts, a rule-based method is proposed in this paper, for prognostics
    and health management (PHM) and specifically for diagnostics. The proposed method
    utilizes the most relevant sensor signals acquired via feature extraction and
    selection techniques and expert knowledge. As a case study, the presented method
    is evaluated on data from a real-world quality control set-up provided by the
    European prognostics and health management society (PHME) at the conference’s
    2021 data challenge. With the proposed method, our team took the third place,
    capable of successfully diagnosing different fault modes, irrespective of varying
    conditions.

  text: <jats:p>Helhmoltz–Kirchhoff equations of motions of vortices of an incompressible
    fluid in the plane define a dynamics with singularities and this leads to a Zermelo
    navigation problem describing the ship travel in such a field where the control
    is the heading angle. Considering one vortex, we define a time minimization problem
    which can be analyzed with the technics of geometric optimal control combined
    with numerical simulations, the geometric frame being the extension of Randers
    metrics in the punctured plane, with rotational symmetry. Candidates as minimizers
    are parameterized thanks to the Pontryagin Maximum Principle as extremal solutions
    of a Hamiltonian vector field. We analyze the time minimal solution to transfer
    the ship between two points where during the transfer the ship can be either in
    a strong current region in the vicinity of the vortex or in a weak current region.
    The analysis is based on a micro-local classification of the extremals using mainly
    the integrability properties of the dynamics due to the rotational symmetry. The
    discussion is complex and related to the existence of an isolated extremal (Reeb)
    circle due to the vortex singularity. The explicit computation of cut points where
    the extremal curves cease to be optimal is given and the spheres are described
    in the case where at the initial point the current is weak.</jats:p>

  text: "This work considers the problem of control and resource allocation in networked\r\nsystems.
    To this end, we present DIRA a Deep reinforcement learning based Iterative Resource\r\nAllocation
    algorithm, which is scalable and control-aware. Our algorithm is tailored towards\r\nlarge-scale
    problems where control and scheduling need to act jointly to optimize performance.\r\nDIRA
    can be used to schedule general time-domain optimization based controllers. In
    the present\r\nwork, we focus on control designs based on suitably adapted linear
    quadratic regulators. We\r\napply our algorithm to networked systems with correlated
    fading communication channels. Our\r\nsimulations show that DIRA scales well to
    large scheduling problems."

  text: "<jats:title>Zusammenfassung</jats:title>\r\n               <jats:p>Zukünftige
    Regelungskonzepte werden verstärkt auf Cloud-Computing und verteiltes Rechnen
    setzen. In den resultierenden vernetzten Regelungssystemen werden sensible Daten
    über öffentliche Netzwerke kommuniziert und auf Plattformen Dritter verarbeitet.
    Verschlüsselte Regelungen zielen darauf ab, die Vertraulichkeit dieser Daten im
    gesamten Regelkreis zu sichern. Um dieses Ziel zu erreichen, werden klassische
    Regelungsalgorithmen so modifiziert, dass sie verschlüsselte Regeleingriffe basierend
    auf verschlüsselten Systemzuständen berechnen. Zum Einsatz kommen dabei homomorphe
    Verschlüsselungsverfahren, die einfache mathematische Operationen auf verschlüsselten
    Daten ermöglichen. Der Artikel erläutert die Implementierung verschlüsselter Regelungen
    anhand von drei wegweisenden Realisierungen in der Cloud.</jats:p>"

  text: Reliability-adaptive systems allow an adaptation of system behavior based
    on current system reliability. They can extend their lifetime at the cost of lowered
    performance or vice versa. This can be used to adapt failure behavior according
    to a maintenance plan, thus increasing availability while using up system capability
    fully. To facilitate setup, a control algorithm independent of a degradation model
    is desired. A closed loop control technique for reliability based on a health
    index, a measure for system degradation, is introduced. It uses self-optimization
    as means to implement behavior adaptation. This is based on selecting the priorities
    of objectives that the system pursues. Possible working points are computed beforehand
    using model-based multiobjective optimization techniques. The controller selects
    the priorities of objectives and this way balances reliability and performance.
    As exemplary application, an automatically actuated single plate dry clutch is
    introduced. The entire reliability control is setup and lifetime experiments are
    conducted. Results show that the variance of time to failure is reduced greatly,
    making the failure behavior more predictable. At the same time, the desired usable
    lifetime can be extended at the cost of system performance to allow for changed
    maintenance intervals. Together, these possibilities allow for greater system
    usage and better planning of maintenance.

  text: 'Recent studies highlight early childhood teachers’ mathematics-related competence.
    Developing this competence should be a main aspect of early childhood teachers’
    education. This is, however, not the case in all countries. Consequently, high-quality
    professional development courses are needed. Based on research results, we developed
    a competence-oriented continuous professional development course ("EmMa") and
    examined the effects of "EmMa" by asking: How does "EmMa" affect the development
    of early childhood teachers’ i) mathematical content knowledge, ii) mathematical
    pedagogical content knowledge and iii) beliefs towards mathematics in general?
    To answer these questions, we conducted a pre-test/post-test study including a
    control group with 99 in-service early childhood teachers. Results show that the
    course affected teachers’ mathematical pedagogical content knowledge and static
    orientation towards mathematics positively. From this we conclude that scaling-up
    "EmMa" might be a suitable approach to bridge the gap between pre-service education
    with nearly no mathematics and the challenges of early mathematics education.'

  text: "Version Control Systems (VCS) are a valuable tool for software development\r\nand
    document management. Both client/server and distributed (Peer-to-Peer)\r\nmodels
    exist, with the latter (e.g., Git and Mercurial) becoming\r\nincreasingly popular.
    Their distributed nature introduces complications,\r\nespecially concerning security:
    it is hard to control the dissemination of\r\ncontents stored in distributed VCS
    as they rely on replication of complete\r\nrepositories to any involved user.\r\n\r\nWe
    overcome this issue by designing and implementing a concept for\r\ncryptography-enforced
    access control which is transparent to the user. Use\r\nof field-tested schemes
    (end-to-end encryption, digital signatures) allows\r\nfor strong security, while
    adoption of convergent encryption and\r\ncontent-defined chunking retains storage
    efficiency. The concept is\r\nseamlessly integrated into Mercurial---respecting
    its distributed storage\r\nconcept---to ensure practical usability and compatibility
    to existing\r\ndeployments."
