text: Data-driven models for nonlinear dynamical systems based on approximating
the underlying Koopman operator or generator have proven to be successful tools
for forecasting, feature learning, state estimation, and control. It has become
well known that the Koopman generators for control-affine systems also have affine
dependence on the input, leading to convenient finite-dimensional bilinear approximations
of the dynamics. Yet there are still two main obstacles that limit the scope of
current approaches for approximating the Koopman generators of systems with actuation.
First, the performance of existing methods depends heavily on the choice of basis
functions over which the Koopman generator is to be approximated; and there is
currently no universal way to choose them for systems that are not measure preserving.
Secondly, if we do not observe the full state, we may not gain access to a sufficiently
rich collection of such functions to describe the dynamics. This is because the
commonly used method of forming time-delayed observables fails when there is actuation.
To remedy these issues, we write the dynamics of observables governed by the Koopman
generator as a bilinear hidden Markov model, and determine the model parameters
using the expectation-maximization (EM) algorithm. The E-step involves a standard
Kalman filter and smoother, while the M-step resembles control-affine dynamic
mode decomposition for the generator. We demonstrate the performance of this method
on three examples, including recovery of a finite-dimensional Koopman-invariant
subspace for an actuated system with a slow manifold; estimation of Koopman eigenfunctions
for the unforced Duffing equation; and model-predictive control of a fluidic pinball
system based only on noisy observations of lift and drag.

text: "Ultraschallsysteme für das Herstellen für Bond- und Schweißverbindungen in
der Halbleiterfertigung zeigen auf Grund des Betriebes unter hohen Anregungsniveaus
nichtlineare Materialeigenschaften. Dabei wirken unterschiedliche Einflussfaktoren
auf die elektrischen Eigenschaften und die mechanischen Übertragungscharakteristiken
der Ultraschallsysteme ein. Die Herausforderungen ein solches geprägtes System
auszulegen oder effizient und zuverlässig zu betreiben, sind aufgrund der Nichtlinearitäten
relativ groß.\r\nDa für die Beschreibung der nichtlinearen Materialbeziehungen
nur wenige Modelle und kaum quantitative Angaben vorliegen, werden die komplexen
Wechselwirkungen von Materialparametern, Geometrie und Vorspannung des Schwingers,
Betriebsgrößen (Strom, Spannung), Temperatur und Prozesslasten durch systematische
Untersuchungen von Keramiken und Langevin-Schwingern messtechnisch erfasst. Aus
den Messergebnissen werden einerseits eindimensionale Modelle für Voruntersuchungen
als auch vollständige Materialparametersätze für die Simulation mittels dreidimensionaler
FE-Modelle hergeleitet.\r\nEine Methodik zur Ermittlung der Materialparameter
und ein auf iterativen Simulationen von FE-Modellen basierendes Werkzeug zur Simulation
der komplexen Wechselwirkungen werden vorgestellt. Anhand eines exemplarischen
Ultraschallsystems wird gezeigt, dass die Wirkungen temperaturbedingter Vorspannungsverluste,
Änderungen des elektrischen Klemmenverhaltens und Amplituden- und Frequenzänderungen
während des Betriebes bei großen Amplituden und Prozesslasten durch die Variationen
des Keramikvolumens und der Keramikposition positiv beeinflusst werden können."

text: Resistance spot‐welded joints containing press‐hardened steels are
seen to exhibit a fracture mode called total dome failure, where the weld nugget
completely separates from one steel sheet along the weld nugget edge. The effect
of weld nugget shape and material property gradients is studied based on damage
mechanics modeling and experimental validation to shed light on the underlying
influencing factors. For a three‐steel‐sheet spot‐welded joint combining DP600
(1.5 mm)–CR1900T (1.0 mm)–CR1900T (1.0 mm), experiments under shear loading reveal
that fracture occurs in the DP600 sheet along the weld nugget edge. In subsequent
numerical simulation studies with damage mechanics models whose parameters are
independently calibrated for every involved material configuration, three variations
of the geometrical joint configuration are considered—an approximation of the
real joint, one variation with a steeper weld nugget shape, and one variation
with a less pronounced gradient between weld nugget material and heat‐affected
zone material properties. The results of the finite‐element simulations show that
a shallower weld nugget and a more pronounced material gradient lead to a faster
increase of plastic strain at the edge of the weld nugget and promote the occurrence
of total dome failure.

text: AbstractFootball is one of the most played
sports in the world and kicking with adequate accuracy increases the likelihood
of winning a competition. Although studies with different target-directed movements
underline the role of distinctive cortical activity on superior accuracy, little
is known about cortical dynamics associated with kicking. Mobile electroencephalography
is a popular tool to investigate cortical modulations during movement, however,
inherent and artefact-related pitfalls may obscure the reliability of functional
sources and their activity. The purpose of this study was therefore to describe
consistent cortical dynamics underlying target-directed pass-kicks based on test–retest
reliability estimates. Eleven participants performed a target-directed kicking
task at two different sessions within one week. Electroencephalography was recorded
using a 65-channel mobile system and behavioural data were collected including
motion range, acceleration and accuracy performance. Functional sources were identified
using independent component analysis and clustered in two steps with the components
of first and subsequently both sessions. Reliability estimates of event-related
spectral perturbations were computed pixel-wise for participants contributing
with components of both sessions. The parieto-occipital and frontal clusters were
reproducible for the same majority of the sample at both sessions. Their activity
showed consistent alpha desyhronization and theta sychnronisation patterns with
substantial reliability estimates revealing visual and attentional demands in
different phases of kicking. The findings of our study reveal prominent cortical
demands during the execution of a target-directed kick which may be considered
in practical implementations and provide promising academic prospects in the comprehension
and investigation of cortical activity associated with target-directed movements.

text: ELDIRK methods are defined to have an Explicit Last
stage in the general Butcher array of Diagonal Implicit Runge-Kutta
methods, with the consequence, that no additional system of equations must be
solved, compared to the embedded RK method. Two general formulations for second-
and third-order ELDIRK methods have been obtained recently in Mahnken [21] with
specific schemes, e.g. for the embedded implicit Euler method, the embedded trapezoidal-rule
and the embedded Ellsiepen method. In the first part of this paper, we investigate
some general stability characteristics of ELDIRK methods, and it will be shown
that the above specific RK schemes are not A-stable. Therefore, in the second
part, the above-mentioned general formulations are used for further stability
investigations, with the aim to construct new second- and third-order ELDIRK methods
which simultaneously are A-stable. Two numerical examples are concerned with the
curing for a thermosetting material and phase-field RVE modeling for crystallinity
and orientation. The numerical results confirm the theoretical results on convergence
order and stability.

abstract:

text: "Context\r\nStatic analyses are well-established to aid in understanding bugs
or vulnerabilities during the development process or in large-scale studies. A
low false-positive rate is essential for the adaption in practice and for precise
results of empirical studies. Unfortunately, static analyses tend to report where
a vulnerability manifests rather than the fix location. This can cause presumed
false positives or imprecise results.\r\nMethod\r\nTo address this problem, we
designed an adaption of an existing static analysis algorithm that can distinguish
between a manifestation and fix location, and reports error chains. An error chain
represents at least two interconnected errors that occur successively, thus building
the connection between the fix and manifestation location. We used our tool CogniCryptSUBS
for a case study on 471 GitHub repositories, a performance benchmark to compare
different analysis configurations, and conducted an expert interview.\r\nResult\r\nWe
found that 50 % of the projects with a report had at least one error chain. Our
runtime benchmark demonstrated that our improvement caused only a minimal runtime
overhead of less than 4 %. The results of our expert interview indicate that with
our adapted version participants require fewer executions of the analysis.\r\nConclusion\r\nOur
results indicate that error chains occur frequently in real-world projects, and
ignoring them can lead to imprecise evaluation results. The runtime benchmark
indicates that our tool is a feasible and efficient solution for detecting error
chains in real-world projects. Further, our results gave a hint that the usability
of static analyses may benefit from supporting error chains."
