text: Modern companies often face various challenges in concept development of products
or systems. Design engineers prepare initial concepts as 3D models. These are
then simulated by computational engineers. If requirements are not met, this necessitates
an iterative process that runs between the design and computation departments
until a valid concept is created. Design methods such as topology optimization
are often used here. The upcoming result is then attempted to be adapted to certain
manufacturing processes. These iteration loops can sometimes take a very long
time, since the model construction and structural optimization generate large
computational efforts. The present work shows on an example a methodical approach,
which represents a first proof of concept, to solving this problem, including
a description of methods and techniques, as well as possible problems in a detailed
analysis concerning training data for neural networks and their abstraction capabilities.
It is evident that additional research work needs to be conducted for further
utilization in order to address all arising questions.

text: "AbstractFeCo alloys are important materials
used in pumps and motors in the offshore oil and gas drilling industry. These
alloys are subjected to marine environments with a high NaCl concentration, therefore,
corrosion and catastrophic failure are anticipated. So, the surface dissolution
of additively manufactured FeCo samples is investigated in a quasi-in
situ manner, in particular, the pitting corrosion in 5.0 wt pct
NaCl solution. The local dissolution of the same sample region is monitored after
24, 72, and 168 hours. Here, the formation of rectangular and circular pits of
ultra-fine dimensions (less than 0.5 µm) is observed
with increasing immersion time. In addition, the formation of a corrosion-inhibiting
surface layer is detected on the sample surface. Surface dissolution leads to
a change in the surface structure, however, no change in grain shape or grain
size is noticed. The surface topography after local dissolution is correlated
to the grain orientation. Quasi-in situ analysis shows
the preferential dissolution of high-angle grain boundaries (HAGBs) leading to
a change in the fraction of HAGBs and low-angle grain boundaries fraction (LAGBs).
For the FeCo sample, a potentiodynamic polarisation test reveals a corrosion potential
(Ecorr) of − 0.475 V referred to the standard hydrogen electrode
(SHE) and a corrosion exchange current density (icorr) of
0.0848 A/m2. Furthermore, quasi-in situ
experiments showed that grains oriented along certain crystallographic directions
are corroding more compared to other grains leading to a significant decrease
in the local surface height. Grains with a plane normal close to the $$\\langle
{1}00\\rangle$$\r\n
\ \r\n ⟨\r\n 100\r\n
\ ⟩\r\n \r\n
direction reveal lower surface dissolution and higher corrosion resistance, whereas
planes normal close to the $$\\langle
{11}0\\rangle$$\r\n
\ \r\n ⟨\r\n 110\r\n
\ ⟩\r\n \r\n
direction and the $$\\langle
{111}\\rangle$$\r\n
\ \r\n ⟨\r\n 111\r\n
\ ⟩\r\n \r\n
direction exhibit a higher surface dissolution."

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: "Zusammenfassung\r\n Aufgrund
aktueller Transformationsprozesse kommt der automatisierten und ressourceneffizienten
Fertigung hochfester Leichtbauteile eine steigende Bedeutung zu, beispielsweise
im Flugzeug- und Fahrzeugbau. Für kleine Losgrößen bietet sich hier insbesondere
das Fertigungsverfahren des Drückwalzens an. Der konventionelle, industriell genutzte
Drückwalzprozess stößt allerdings aufgrund der Prozesskomplexität hinsichtlich
der Reproduzierbarkeit an seine Grenzen. Dies wird in der Praxis teilweise durch
personengebundenes Erfahrungswissen kompensiert. Auch ist es nicht möglich, Bauteileigenschaften
definiert einzustellen. Aus diesem Grund bietet der Einsatz einer neuartigen Eigenschaftsregelung
Chancen zur Weiterentwicklung des Fertigungsprozesses und die Möglichkeit zur
Prozessautomatisierung. Hier werden die Werkzeugbahnen abhängig einer Online-Eigenschaftsmessung
über eine zusätzliche Reglerkaskade manipuliert. Die Entwicklung einer solchen
Eigenschaftsregelung erfordert den Einsatz geeigneter, modellbasierter Entwurfsmethoden.
In diesem Beitrag wird daher ein regelungstechnisches Systemmodell für das Drückwalzen
metastabiler austenitischer Edelstähle vorgestellt. Das Simulationsmodell weist
aufgrund seiner Echtzeitfähigkeit neben dem Einsatz als reines Entwurfsmodell
weitere Nutzungsmöglichkeiten z.B. in Beobachtern auf und grenzt sich somit von
domänenspezifischen Simulationstools wie der FEM ab."

text: Abstract. Climate change, rare resources and industrial transformation
processes lead to a rising demand of multi-complex lightweight forming parts,
especially in aerospace and automotive sectors. In these industries, flow forming
is often used to produce cylindrical forming parts by reducing the wall thickness
of tubular semifinished parts, e.g. for the production of hydraulic cylinders
or gear shafts. The complexity and functionality of flow forming workpieces could
be significantly increased by locally graded microstructure and geometry structures.
This enables customized complex hardness distributions at wear surfaces or magnetic
QR codes for a unique, tamper-proof product identification. The production of
those complex, 2D (axial and angular) graded forming parts currently depicts a
great challenge for the process and requires new solutions and strategies. Hence,
this paper proposes a novel control strategy that includes online measurements
from an absolute encoder to determine the angular workpiece position. Workpieces
of AISI 304L stainless steel with 2D-graded structures are successfully manufactured
using this new strategy and analyzed regarding the possible accuracy and resolution
of the gradation. At this point, a dependency of the gradations on the sensor
and actuator dynamics, accuracy and geometry could be noted. It is further evaluated
how the control strategy could be extended by an observer-based closed-loop property
control approach to enhance the accuracy of the suggested strategy.

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."
