text: 'Twitter ist jetzt X und befindet sich auf dem absteigenden Ast. Auf diesem
Ast sitzt Facebook bereits seit längerem. Der Kurzvideodienst Vine, Vorgänger
von TikTok, ist Geschichte. Und auch bei Google klingeln die Alarmglocken angesichts
der „neuen“ Konkurrenz durch Microsoft und ChatGPT. Umso dringlicher wird also
die Historisierung der „sozialen Medien“, das heißt, sie in ihren historischen
Kontext einzuordnen und ihren Mythos zu entzaubern. Dabei wartet das Vorhaben
mit einer doppelten Herausforderung auf: Erstens, dass es sich bei den Unternehmen
der Branche und zweitens auch bei den dort gebildeten Gemeinschaften um recht
flüchtige, wandelhaften Gestalten handelt. Scheitern und Wandel ist Teil der „sozialen
Medien“ – und sei es nur in der schnellen Abfolge der Moden des „nächsten großen
Dings“. Dementsprechend versucht dieser Beitrag mit einem systematischeren Ansatz
als dem der gesellschaftlichen Selbstbeschreibung, die Entwicklung des sozio-digitalen
Phänomens „soziale Medien“ in dessen Zeitkontext einzuordnen.'

text: AbstractWe conducted an investigation into
the palladium‐catalyzed carbon‐sulfur cross‐coupling reaction involving a 2‐bromothiophene
derivative and potassium thioacetate as a substitute for hydrogen sulfide. This
investigation utilized kinetic and computational methods. We synthesized two palladium
complexes supported by the bisphosphane ligands bis(diphenylphosphino)ferrocene
(DPPF) and bis(diisopropylphosphino)ferrocene (DiPPF),
as well as their tentative intermediates in the catalytic cycle. Reaction rates
were measured and then compared to computational predictions.

text: A series of substituted ferrocenyl boron derivatives was synthesized.
The oxidation of the ferrocenyl unit resulted in a significant increase of the
boron‐centered Lewis acidity. The neutral and cationic Lewis acids were characterized
by NMR‐spectroscopy, crystal structure analysis and by computational methods.
The new Lewis acids were then applied in the Meinwald rearrangement of epoxides,
predominantly furnishing aldehydes as the kinetic products.

text: In applications of piezoelectric actuators and sensors, the dependability
and particularly the reliability throughout their lifetime are vital to manufacturers
and end-users and are enabled through condition-monitoring approaches. Existing
approaches often utilize impedance measurements over a range of frequencies or
velocity measurements and require additional equipment or sensors, such as a laser
Doppler vibrometer. Furthermore, the non-negligible effects of varying operating
conditions are often unconsidered. To minimize the need for additional sensors
while maintaining the dependability of piezoelectric bending actuators irrespective
of varying operating conditions, an online diagnostics approach is proposed. To
this end, time- and frequency-domain features are extracted from monitored current
signals to reflect hairline crack development in bending actuators. For validation
of applicability, the presented analysis method was evaluated on piezoelectric
bending actuators subjected to accelerated lifetime tests at varying voltage amplitudes
and under external damping conditions. In the presence of a crack and due to a
diminished stiffness, the resonance frequency decreases and the root-mean-square
amplitude of the current signal simultaneously abruptly drops during the lifetime
tests. Furthermore, the piezoelectric crack surfaces clapping is reflected in
higher harmonics of the current signal. Thus, time-domain features and harmonics
of the current signals are sufficient to diagnose hairline cracks in the actuators.

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: 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.

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."
