  text: "Zusammenfassung: Die Erfindung betrifft ein Verkehrsleitsystem für die Steuerung
    von Lichtsignalanlagen aufweisend:\r\n• Eingänge für Verkehrszustandsermittlungsverfahren
    abhängig von verschiedenen Sensoren, wobei die Sensoren einen aktuellen Verkehrszustand
    eines zugeordneten Verkehrsabschnitts ermitteln,\r\n• Statusregister, die den
    aktuellen Status der gesteuerten Lichtsignalanlagen speichern,\r\n• Phasenregister,
    die alle möglichen Verkehrsleitphasen, die durch die Lichtsignalanlagen angesteuert
    werden können, speichern,\r\n• eine Fuzzy-Logik (F) zur Vorselektion von möglichen
    Verkehrsleitphasen basierend auf einem aktuellen Verkehrszustand, wobei für jede
    mögliche Verkehrsleitphase basierend auf dem aktuellen Verkehrszustand ein Prioritätswert
    ermittelt wird, wobei für die weitere Verarbeitung nur eine vorbestimmte Anzahl
    von vorselektierten nachfolgenden Verkehrsleitphasen anhand der Priorität ausgewählt
    wird,\r\n• wobei die so vorausgewählten Verkehrsleitphasen einer modellprädiktiven
    Regelung mit einer Verkehrsprädiktionssimulation (MPC) zugeführt werden, wobei
    die Regelung basierend auf den Phasenfolgen (gebildet aus den vorselektierten
    Verkehrsleitphasen), dem aktuellen Verkehrszustand und dem aktuellen Status der
    gesteuerten Lichtsignalanlagen eine geeignete prädiktive zeitliche Phasensteuerung
    ermittelt, wobei die Schaltzeitpunkte der Phasenfolgen durch ein Optimierungsverfahren
    berechnet werden,\r\n• wobei die so ermittelte prädiktive zeitliche Phasensteuerung
    keine, eine oder mehrere zu schaltenden Folgephasen mit den ermittelten Schaltzeitpunkten
    aufweist,\r\n• wobei anhand der Bewertungen der einzelnen prädiktiven zeitlichen
    Phasensteuerungen ermittelt wird, welche der prädiktiven zeitlichen Phasensteuerungen
    zur weiteren Steuerung der Lichtsignalanlagen ausgewählt und verwendet wird."

  text: Ein Trend in der Produktion sind individualisierte Produkte und damit eine
    höhere Variantenvielfalt, die idealerweise durch effiziente Produktionsprozesse
    hergestellt werden. Effizienz bedeutet in diesem Fall, dass die Produkte kostengünstig
    und bedarfsgerecht hergestellt werden. Der Trend geht hierbei auch in der Massenproduktion
    zu einer flexiblen Produktion, um das gebundene Kapital zu reduzieren und zeitnah
    auf Kundenwünsche reagieren zu können. Dies führt zu einem häufigeren Umrüsten
    der Werkzeuge in den Maschinen und somit zu einem immer häufigeren Einrichten
    der Prozesse.In dieser Arbeit wird eine Systematik für ein adaptives Einrichtassistenzsystem
    entwickelt, welches den Maschinenbediener beim Einrichten mithilfe eines definierten
    Vorgehens durch den Prozess leitet. Der Bediener wird dabei unterstützt die momentane
    Produktqualität zu bewerten und bekommt einen quantitativen Vorschlag zur Variation
    der Justagemöglichkeiten. So kann der Einrichtprozess zielgerichteter und fehlerfreier
    durchgeführt werden. Ermöglicht wird dies durch die Abbildung des notwendigen
    Expertenwissens in datengetriebenen Modellen. Mithilfe des so abgebildeten Expertenwissens
    werden optimierte Einstellungen berechnet und am Werkzeug eingestellt. Es ist
    nicht davon auszugehen, dass das virtualisierte Expertenwissen die Realität allumfassend
    abbilden und alle akuten Umwelteinflüsse messtechnisch ermittelt werden können.
    Etwaige Abweichungen der Produktqualität werden direkt in der entwickelten Optimierung
    und bei Bedarf mithilfe der vorgeschlagenen Kompensationsstrategie eliminiert.Die
    Systematik wird anhand eines Folgeverbundprozesses validiert. Nach der Analyse
    des Prozesses werden die wesentlichen Komponenten für das System entwickelt und
    mithilfe von Versuchen und Simulationen die Funktionsfähigkeit erfolgreich nachgewiesen.

  text: A trend in production are individualized products and thus a higher number
    of variants, which are ideally produced by efficient production processes. In
    this case, efficiency means that the products are manufactured at low cost and
    in line with demand. This trend, flexible manufacturing, is also valid for mass
    production, in order to reduce tied up capital and still be able to react promptly
    to customer demands. This leads to more frequent retooling in the machines and
    thus also to an increasingly frequent setting up of the processes.In this thesis,
    a systematic for an adaptive set-up assistant is developed, which guides the machine
    operator through the process during setup. The machine operator is supported in
    evaluating the current product quality and receives a quantitative proposal for
    the variation of the adjustment possibilities. Thus, the set-up process can be
    carried out in a more targeted and error-free manner. This is made possible by
    mapping the necessary expert knowledge in data-driven models. The expert knowledge
    is used to calculate optimized settings and adjust them on the tool. It cannot
    be assumed that virtualized expert knowledge will comprehensively map reality
    and that all acute environmental influences can be measured. Any deviations in
    product quality are directly eliminated in the developed optimization and, if
    necessary, with a proposed compensation strategy.The system is validated with
    a progressive tool. After analyzing the process, the essential components for
    the system are developed and their functionality is successfully demonstrated
    by means of tests and simulations.

  text: State estimation when only a partial model of a considered system is available
    remains a major challenge in many engineering fields. This work proposes a joint,
    square-root unscented Kalman filter to estimate states and model uncertainties
    simultaneously by linear combinations of physics-motivated library functions.
    Using a sparsity promoting approach, a selection of those linear combinations
    is chosen and thus an interpretable model can be extracted. Results indicate a
    small estimation error compared to a traditional square-root unscented Kalman
    filter and exhibit the enhancement of physically meaningful models.

  text: "Low-quality models that miss relevant dynamics lead to major challenges in
    modelbased\r\nstate estimation. We address this issue by simultaneously estimating
    the system’s states\r\nand its model inaccuracies by a square root unscented Kalman
    filter (SRUKF). Concretely,\r\nwe augment the state with the parameter vector
    of a linear combination containing suitable\r\nfunctions that approximate the
    lacking dynamics. Presuming that only a few dynamical terms\r\nare relevant, the
    parameter vector is claimed to be sparse. In Bayesian setting, properties like\r\nsparsity
    are expressed by a prior distribution. One common choice for sparsity is a Laplace\r\ndistribution.
    However, due to disadvantages of a Laplacian prior in regards to the SRUKF,\r\nthe
    regularized horseshoe distribution, a Gaussian that approximately features sparsity,
    is\r\napplied instead. Results exhibit small estimation errors with model improvements
    detected by\r\nan automated model reduction technique."

  text: 'High-strength wire materials are usually available as strip material which
    is further processed in a forming process (e.g. punch-bending). For storage and
    transport of the semi-finished wire to the customer, the material is wound onto
    coils. The manufacturing and coiling process introduces plastic deformations into
    the wire, which lead to undesirable residual stresses and wire curvature of the
    semi-finished product. These residual stresses and curvatures cause variations
    in the material properties of the semi-finished product, which have a negative
    impact on the subsequent product quality. Straightening machines are used to compensate
    the residual stresses and the curvature in the wire. At the beginning of the straightening
    process, the straightening machines must be set up in such a way that residual
    stresses and curvatures are optimally compensated. This setup process is usually
    a manual and iterative process, where a lot of material is wasted until the optimal
    settings for the straightening machine are found.In order to reduce the amount
    of material waste, the operator must be supported in the setup process. In this
    context, a new and innovative setup assistance system was developed to support
    the operator during the setup process. The setup assistant system automatically
    detects the wire curvature by means of an optical measuring system. Based on the
    optically detected measuring points, the wire curvature is determined by a robust
    calculation algorithm. Based on a database built up through the carried out experimental
    and numerical research work, the optimum setting parameters for the straightening
    machine are suggested to the operator without lengthy trial and error. After confirmation
    by the operator, the roller settings are automatically adjusted by the mechatronic
    straightening machine. With the presented method, the conventional iterative setup
    procedure can be made more resource-efficient and a high straightening quality
    can be reproducibly achieved. '

  text: 'Due to increasing globalization and rising quality requirements, the steel
    and metal processing industry is facing growing cost and innovation pressure.
    Not least because of their high lightweight potential, high-strength steel materials
    are meeting the growing material requirements of steel and metal processing in
    areas such as aerospace and medical technology. In particular, the tight tolerance
    limits of applicable shape and dimensional accuracies pose a challenge in the
    processing of high-strength steel strip materials. Improving the processability
    of high-strength steel materials through the use of straighteners with set-up
    assistance systems significantly increases the potential for competing with other
    materials such as aluminum or magnesium alloys. '

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>This paper presents
    the characterization of the microstructure evolution during flow forming of austenitic
    stainless steel AISI 304L. Due to plastic deformation of metastable austenitic
    steel, phase transformation from γ-austenite into α’-martensite occurs. This is
    initiated by the formation of shear bands as product of the external stresses.
    By means of coupled microscopic and micromagnetic investigations, a characterization
    of the microstructure was carried out. In particular, this study shows the distribution
    of the strain-induced α’-martensite and its influence on material properties like
    hardness at different depths. The microstructural analyses by means of electron
    backscattered diffraction (EBSD) technique, evidence a higher amount of α’-martensite
    (ca. 23 %) close to the outer specimen surface, where the plastic deformation
    and the direct contact with the forming tool take place. In the middle area (ca.
    1.5 mm depth from the outer surface), the portion of transformed α’-martensite
    drops to 7 % and in the inner surface to 2 %. These results are well correlated
    with microhardness and micromagnetic measurements at different depths. EBSD and
    atomic force microscopy (AFM) were used to make a detailed characterization of
    the topography and degree of deformation of the shear bands. Likewise, the mechanisms
    of nucleation of α’-martensite were discussed. This research contributes to the
    development of micromagnetic sensors to monitor the evolution of properties during
    flow forming. This makes them more suitable for closed-loop property control,
    which offers possibilities for an application-oriented and more efficient production.</jats:p>"

  text: <jats:p>The production of complex multi-functional, high-strength parts is
    becoming increasingly important in the industry. Especially with small batch size,
    the incremental flow forming processes can be advantageous. The production of
    parts with complex geometry and locally graded material properties currently depicts
    a great challenge in the flow forming process. At this point, the usage of closed-loop
    control for the shape and properties could be a feasible new solution. The overall
    aim in this project is to establish an intelligent closed-loop control system
    for the wall thickness as well as the α’-martensite content of AISI 304L-workpieces
    in a flow forming process. To reach this goal, a novel sensor concept for online
    measurements of the wall thickness reduction and the martensite content during
    forming process is proposed. It includes the setup of a modified flow forming
    machine and the integration of the sensor system in the machine control. Additionally,
    a simulation model for the flow forming process is presented which describes the
    forming process with regard to the plastic workpiece deformation, the induced
    α’-martensite fraction, and the sensor behavior. This model was used for designing
    a closed-loop process control of the wall thickness reduction that was subsequently
    realized at the real plant including online measured feedback from the sensor
    system.</jats:p>
