text: In this contribution, we address the estimation of the frequency-dependent
elastic parameters of polymers in the ultrasound range, which is formulated as
an inverse problem. This inverse problem is implemented as a nonlinear regression-type
optimization problem, in which the simulation signals are fitted to the measurement
signals. These signals consist of displacement responses in waveguides, focusing
on hollow cylindrical geometries to enhance the simulation efficiency. To accelerate
the optimization and reduce the number of model evaluations and wait times, we
propose two novel methods. First, we introduce an adaptation of the Levenberg–Marquardt
method derived from a geometrical interpretation of the least-squares optimization
problem. Second, we introduce an improved objective function based on the autocorrelated
envelopes of the measurement and simulation signals. Given that this study primarily
relies on simulation data to quantify optimization convergence, we aggregate the
expected ranges of realistic material parameters and derive their distributions
to ensure the reproducibility of optimizations with proper measurements. We demonstrate
the effectiveness of our objective function modification and step adaptation for
various materials with isotropic material symmetry by comparing them with the
Broyden–Fletcher–Goldfarb–Shanno method. In all cases, our method reduces the
total number of model evaluations, thereby shortening the time to identify the
material parameters.

text: Light-emitting diodes (LEDs) are becoming increasingly important across various
sectors of the lighting industry and are being used more frequently. In the field
of symbolic projection, research is increasingly focusing on implementing light
modulation using energy-efficient, incoherent LEDs rather than lasers. Since light
modulation in micro- and nano-optics is typically achieved through phase modulation,
Finite-Difference Time-Domain (FDTD) simulations are employed for analysis. The
objective of this article is to investigate different approaches for approximating
incoherent monochromatic light sources within FDTD simulations. To this end, two
approaches based on dipole sources are considered, as well as a method involving
plane waves with modulated wavefronts based on Cosine–Fourier functions and a
method based on the superposition of Gaussian beams. These methods are evaluated
in terms of their accuracy using a two-dimensional double-slit configuration and
are compared against a fully incoherent analytical reference.

text: "Industrial electrification is increasing to reduce fossil fuel dependence,
alongside a growing share of volatile renewables.\r\nA secure and reliable energy
supply is crucial for industry, leading to a shift from centralised to decentralised
grid structures.\r\nDC microgrids becoming increasingly popular in industry, since
they enable energy recuperation from braking, reduce components and cables, and
integrate storage and local generation to manage supply interruptions or peak
loads.\r\nEVs add further synergies by serving as mobile storage units, helping
to store and redistribute locally generated renewable energy.\r\nThis paper analyses
how EV integration in droop-controlled DC grids can contribute to a more stable,
low-emission and peak-reduced load profile to the supply grid through load shifting
and bridge interruptions.\r\nA droop-controlled DC grid model has been developed,
incorporating an EV charging park based on probability functions.\r\nScalable
scenarios allow for diverse condition analysis using an energy management system
that utilises fuzzy logic and sequential MILP optimisation.\r\nIt has been shown
that a 7% improvement of coefficient represented grid-serving behaviour is possible
by load shifting.\r\nIt has also been demonstrated that an optimised EMS can reduce
the demand-based CO2 emissions by 41kg for a representative day compared to a
fuzzy logic EMS.\r\nAt the same time peak load is decreased yielding a more constant
residual load.\r\nThese results highlight the potential of a controlled bidirectional
charging infrastructure in DC grids and underscore the need to explicitly consider
charging processes to ensure a residual load as constant as possible."

text: Room-temperature lasing is a key milestone in the development of miniaturized
optoelectronic and photonic devices. We present a simple approach to synthesize
phase-pure quasi-2D layered tin perovskite nanowires with varying quantum well
thicknesses (n = 1 to 4). By incorporating a new organic spacer capable of forming
a hydrogen-bonded organic framework, this method promoted anisotropic crystal
growth and enhanced lattice rigidity. Furthermore, introducing molecular intercalants
enabled controlled crystallization into well-defined nanowires that function as
Fabry–Pérot cavities. Cavities made from n = 2 to 4 perovskites support efficient
and robust near-infrared, room-temperature optically pumped lasing with the threshold
as low as 75.8 μJ/cm2, cavity quality factor over 3000, and negligible degradation
over 106 pulses. A cleaved coupled nanolaser was fabricated as a proof-of-concept
device for photonic applications.

text: "Abstract\r\n With the growing
demand for lightweight solutions to reduce emissions, especially in the transportation,
automotive and aerospace sectors, recyclable, continuous fiber-reinforced plastic
composite laminates with a thermoplastic matrix are of rising interest. To achieve
their maximum mechanical properties, the fiber-matrix adhesion (FMA) is critical.
In this work, continuous fiber-reinforced thermoplastic laminates (CFRTPL) with
a polypropylene (PP) matrix and twill woven glass fiber fabrics are produced by
film stacking. The films used contain different amounts of maleic-anhydride-grafted
PP (MA-g-PP) as a coupling agent to produce CFRTPL of different mechanical strengths.
To analyze the FMA, the CFRTPL are subjected to Charpy-impact and tensile tests.
Additionally, single fiber pull-out tests (SFPT) are conducted to further investigate
the effect of MA-g-PP on the FMA. The results of the SFPT show an improvement
in apparent interfacial shear strength (AIFSS) when the MA-g-PP content is increased,
which can be attributed to an increase in FMA. However, the research shows that
MA-g-PP has a low impact on the mechanical properties if the force is applied
parallel to the warp and weft threads during tensile testing and the results of
the Charpy-impact testing suffer from embrittlement of the matrix material. Subsequently,
the results of this study are compared to three-point flexural tests conducted
in a previous study. It can be concluded that tensile and impact tests are not
suited to investigate FMA on a macroscopic scale, while SFPT and flexural tests
provide a better alternative."

text: "Woven fibre-reinforced polymers are used in a variety of application, especially
where a low mass to stiffness ratio is required. Of paramount importance for the
tailored mechanical properties these composite materials exhibit is the type and
geometry of the fibre weave. Especially continuous fibre-reinforced thermoplastic
composites are fabricated as laminates and subsequently exposed to forming processes
which alter the geometry of the fibres unit cell and thus the local mechanical
properties of the material. An approach utilising broadband ultrasonic waves is
proposed to non-destructively determine the geometry of the unit cell of the weave.\r\n\r\nThe
dispersive behaviour of woven fibre-reinforced sheets is described in accordance
with the Flouquet-Bloch theorem as a phononic crystal. In order to develop a model
for a description of these periodically structured waveguides, the smallest repeating
unit of the wave is modelled with periodic boundary conditions. The resulting
dispersion diagram exhibits similarities to that of a homogeneous plate, but additionally
displays a periodicity in the wavenumber regime, which correspond with the size
of the unit cell. Experimental studies of the dispersive behaviour of acoustic
waves in woven fibre-reinforced samples also show a periodicity in the wavenumber
regime, enabling a measurement procedure of the unit cell geometry."

text: The LLC converter achieves the highest efficiency in resonant operation. Conventionally,
the input DC-link voltage is controlled to operate the LLC converter at resonance
for the given operating point. However, the DC-link capacitor voltage shows a
low-frequency voltage ripple (typically the second harmonic of grid frequency)
in cascaded converters so that the LLC has to adapt its switching frequency within
the grid period. Conventionally, the LLC converter operates 50% of the time above
the resonant frequency of 40 kHz and 50% below resonance. Both operating conditions
cause additional losses. However, experimental measurements indicate that the
below-resonance operation causes significantly higher losses than above-resonance
operation due to much higher primary and secondary transformer currents. It is
better to increase the DC-link voltage by 30% of the peak-to-peak low-frequency
voltage ripple to mostly avoid below-resonance operation (i.e., from 650 V to
680 V in this case). With the proposed control, the LLC converter operates about
75% of time over resonance and only 25% of time below resonance. The overall efficiency
increases from 97.66% to 97.7% for the average operating point with an 80% load
current. This corresponds to a 2% total loss reduction. Finally, the peak resonance
capacitor voltage decreases from 910 V to 790 V (−13%).
