text: "Abstract. The miniaturisation of components leads to new demands on measurement
systems. One of these is the resolution. As a volumetric analysis method and method
of non-destructive testing, industrial X-ray computed\r\ntomography (XCT) has
the ability to measure geometrical features and their corresponding dimensions
without destroying them and can therefore be used for quality assurance. However,
the concept of resolution is not trivial for XCT and has not yet been finally
clarified. In particular, the interface structural resolution, the detectability
of two surfaces facing each other after surface segmentation, faces a lack of
a test specimen, a corresponding\r\nmeasurand and a reliable method. Simulation-based
XCT investigations of a method to determine this type of resolution are presented
in this article using the geometry of a test specimen that contains several radially\r\narranged
holes of the same size. The borehole diameters correspond to the distance between
the holes to investigate the resolvability of surfaces and interfaces. The evaluation
is based on mean and extreme values of grey value\r\nprofiles between the individual
boreholes of the reconstructed volume. It is shown that the geometrical detectability
of the test specimen surface and interface can be extended by a reasonable choice
of the threshold value for\r\nsurface segmentation within a defined interval.
With regard to the resolving capability, a distinction is made between assured
detectability and possible detectability, as well as the threshold value used
when using the ISO50\r\nthreshold for surface segmentation and measurement chain
completion. "

text: The production of hydrogen and the utilization of biomass for sustainable
concepts of energy conversion and storage require gas sensors that discriminate
between hydrogen (H2) and carbon monoxide (CO). Mesoporous copper–ceria (Cu–CeO2)
materials with large specific surface areas and uniform porosity are prepared
by nanocasting, and their textural properties are characterized by N2 physisorption,
powder XRD, scanning electron microscopy, transmission electron microscopy, and
energy-dispersive X-ray spectroscopy. The oxidation states of copper (Cu+, Cu2+)
and cerium (Ce3+, Ce4+) are investigated by XPS. The materials are used as resistive
gas sensors for H2 and CO. The sensors show a stronger response to CO than to
H2 and low cross-sensitivity to humidity. Copper turns out to be a necessary component;
copper-free ceria materials prepared by the same method show only poor sensing
performance. By measuring both gases (CO and H2) simultaneously, it is shown that
this behavior can be utilized for selective sensing of CO in the presence of H2.

text: 'The aim of the present study was to investigate if the presence of
anterior cruciate ligament (ACL) injury risk factors depicted in the laboratory
would reflect at-risk patterns in football-specific field data. Twenty-four female
footballers (14.9 ± 0.9 year) performed unanticipated cutting maneuvers in a laboratory
setting and on the football pitch during football-specific exercises (F-EX) and
games (F-GAME). Knee joint moments were collected in the laboratory and grouped
using hierarchical agglomerative clustering. The clusters were used to investigate
the kinematics collected on field through wearable sensors. Three clusters emerged:
Cluster 1 presented the lowest knee moments; Cluster 2 presented high knee extension
but low knee abduction and rotation moments; Cluster 3 presented the highest knee
abduction, extension, and external rotation moments. In F-EX, greater knee abduction
angles were found in Cluster 2 and 3 compared to Cluster 1 (p = 0.007). Cluster
2 showed the lowest knee and hip flexion angles (p < 0.013). Cluster 3 showed
the greatest hip external rotation angles (p = 0.006). In F-GAME, Cluster 3 presented
the greatest knee external rotation and lowest knee flexion angles (p = 0.003).
Clinically relevant differences towards ACL injury identified in the laboratory
reflected at-risk patterns only in part when cutting on the field: in the field,
low-risk players exhibited similar kinematic patterns as the high-risk players.
Therefore, in-lab injury risk screening may lack ecological validity.'

text: Sport-related concussions (SRC) are characterized by impaired autonomic
control. Heart rate variability (HRV) offers easily obtainable diagnostic approaches
to SRC-associated dysautonomia, but studies investigating HRV during sleep, a
crucial time for post-traumatic cerebral regeneration, are relatively sparse.
The aim of this study was to assess nocturnal HRV in athletes during their return
to sports (RTS) after SRC in their home environment using wireless wrist sensors
(E4, Empatica, Milan, Italy) and to explore possible relations with clinical concussion-associated
sleep symptoms. Eighteen SRC athletes wore a wrist sensor obtaining photoplethysmographic
data at night during RTS as well as one night after full clinical recovery post
RTS (>3 weeks). Nocturnal heart rate and parasympathetic activity of HRV (RMSSD)
were calculated and compared using the Mann–Whitney U Test to values of eighteen;
matched by sex, age, sport, and expertise, control athletes underwent the identical
protocol. During RTS, nocturnal RMSSD of SRC athletes (Mdn = 77.74 ms) showed
a trend compared to controls (Mdn = 95.68 ms, p = 0.021, r = −0.382, p adjusted
using false discovery rate = 0.126) and positively correlated to “drowsiness”
(r = 0.523, p = 0.023, p adjusted = 0.046). Post RTS, no differences in RMSSD
between groups were detected. The presented findings in nocturnal cardiac parasympathetic
activity during nights of RTS in SRC athletes might be a result of concussion,
although its relation to recovery still needs to be elucidated. Utilization of
wireless sensors and wearable technologies in home-based settings offer a possibility
to obtain helpful objective data in the management of SRC.

text: In this study, quasi-unidirectional continuous fiber reinforced thermoplastics
(CFRTs) are joined with metal sheets via cold formed cylindrical, elliptical and
polygonal pin structures which are directly pressed into the CFRT component after
local infrared heating. In comparison to already available studies, the unique
novelty is the use of non-rotational symmetric pin structures for the CFRT/metal
hybrid joining. Thus, a variation in the fiber orientation in the CFRT component
as well as a variation in the non-rotational symmetric pins’ orientation in relation
to the sample orientation is conducted. The created samples are consequently mechanically
tested via single lap shear experiments in a quasi-static state. Finally, the
failure behavior of the single lap shear samples is investigated with the help
of microscopic images and detailed photographs. In the single lap shear tests,
it could be shown that non-rotational symmetric pin structures lead to an increase
in maximum testing forces of up to 74% when compared to cylindrical pins. However,
when normalized to the pin foot print related joint strength, only one polygonal
pin variation showed increased joint strength in comparison to cylindrical pin
structures. The investigation of the failure behavior showed two distinct failure
modes. The first failure mode was failure of the CFRT component due to an exceedance
of the maximum bearing strength of the pin-hole leading to significant damage
in the CFRT component. The second failure mode was pin-deflection due to the applied
testing load and a subsequent pin extraction from the CFRT component resulting
in significantly less visible damage in the CFRT component. Generally, CFRT failure
is more likely with a fiber orientation of 0° in relation to the load direction
while pin extraction typically occurs with a fiber orientation of 90°. It is assumed
that for future investigations, pin structures with an undercutting shape that
creates an interlocking joint could counteract the tendency for pin-extraction
and consequently lead to increased maximum joint strengths.

text: Unter dem Begriff der Auflösung wird für gewöhnlich das kleinste messbare
Merkmal eines Messsystems verstanden. In der dimensionellen Computertomografie
hingegen haben sich in den vergangenen Jahren mehrere Auflösungskonzepte etabliert,
die aufgrund der fehlenden Normung zueinander im Kontrast stehen. In diesem Beitrag
werden die drei häufigsten Konzepte, die Voxelgröße, die Ortsauflösung und die
metrologische Strukturauflösung in Kürze vorgestellt. Anschließend wird eine Abgrenzung
zwischen den Konzepten getroffen und ein Integration der bestehenden Konzepte
in ein gemeinsames Amplituden-Wellenlängen Diagramm diskutiert.

text: In industrial x-ray computed tomography (CT), the application of more complex
scan paths in comparison to the typical circular trajectory (${360}^{\circ}$ rotation
of the measurement object) can extend the potential of CT. One way to enable such
3D scan trajectories is to use a 6-degrees-of-freedom (DOF) object manipulator
system. In our case, a hexapod is mounted on top of the rotary table of a commercial
CT scanner. This allows for adaptive tilting of the measurement object during
the scan. For high accuracy, the geometry calibration of such setups is typically
done using the x-ray projections of a calibrated multi-sphere object. Contrary
to this, here, we demonstrate a procedure that is based on only a single sphere
and can therefore experimentally be implemented with low effort. Using the intrinsic
geometry parameters of the CT device as prior information, the hexapod coordinate
system with respect to the CT machine coordinate system is determined by means
of a one-step optimization approach. The resulting parameters are used to calculate
projection matrices that enable the volume reconstruction for 3D scan trajectories.
The method is validated using simulated x-ray images and experimental investigations
including dimensional measurements. For the used setup, geometric measurement
results for 3D scan trajectories that are calibrated with the presented method
show in sum increased errors compared to the circular scans. A limited pose accuracy
of the manipulator system is discussed as a potential cause. The results nevertheless
indicate that the presented method is generally feasible for dimensional CT measurements
provided that the pose accuracy is sufficient. The calibration procedure can therefore
be a low-cost and easier to implement alternative compared to trajectory calibration
methods based on multi-sphere objects, but with a tendency towards lower measurement
accuracy. The methodology can in principle be transferred to different setups
with 6-DOF manipulator systems, e.g. C-arm CT devices with a robot arm.

text: Crack growth in structures depends on the cyclic loads applied on it, such
as mechanical, thermal and contact, as well as residual stresses, etc. To provide
an accurate simulation of crack growth in structures, it is of high importance
to integrate all kinds of loading situations in the simulations. Adapcrack3D is
a simulation program that can accurately predict the propagation of cracks in
real structures. However, until now, this three-dimensional program has only considered
mechanical loads and static thermal loads. Therefore, the features of Adapcrack3D
have been extended by including contact loading in crack growth simulations. The
numerical simulation of crack propagation with Adapcrack3D is generally carried
out using FE models of structures provided by the user. For simulating models
with contact loading situations, Adapcrack3D has been updated to work with FE
models containing multiple parts and necessary features such as coupling and surface
interactions. Because Adapcrack3D uses the submodel technique for fracture mechanical
evaluations, the architecture of the submodel is also modified to simulate models
with contact definitions between the crack surfaces. This paper discusses the
newly implemented attribute of the program with the help of illustrative examples.
The results confirm that the contact simulation in Adapcrack3D is a major step
in improving the functionality of the program.

text: Requirement changes and cascading effects of change propagation are
major sources of inefficiencies in product development and increase the risk of
project failure. Proactive change management of requirement changes yields the
potential to handle such changes efficiently. A systematic approach is required
for proactive change management to assess and reduce the risk of a requirement
change with appropriate effort in industrial application. Within the paper at
hand, a novel method for Proactive Management of Requirement Changes (ProMaRC)
is presented. It is developed in close collaboration with industry experts and
evaluated based on workshops, pilot users’ feedback, three industrial case studies
from the automotive industry and five development projects from research. To limit
the application effort, an automated approach for dependency analysis based on
the machine learning technique BERT and semi-automated assessment of change likelihood
and impact using a modified PageRank algorithm is developed. Applying the method,
the risks of requirement changes are assessed systematically and reduced by means
of proactive change measures. Evaluation shows high performance of dependency
analysis and confirms the applicability and usefulness of the method. This contribution
opens up the research space of proactive risk management for requirement changes
which is currently almost unexploited. It enables more efficient product development.

text: "Abstract\r\n In this paper
a measurement procedure to identify viscoelastic material parameters of plate-like
samples using broadband ultrasonic waves is presented. Ultrasonic Lamb waves are
excited via the thermoelastic effect using laser radiation and detected by a piezoelectric
transducer. The resulting measurement data is transformed to yield information
about multiple propagating Lamb waves as well as their attenuation. These results
are compared to simulation results in an inverse procedure to identify the parameters
of an elastic and a viscoelastic material model."

text: AbstractColloidal nanosphere monolayers—used
as a lithography mask for site-controlled material deposition or removal—offer
the possibility of cost-effective patterning of large surface areas. In the present
study, an automated analysis of scanning electron microscopy (SEM) images is described,
which enables the recognition of the individual nanospheres in densely packed
monolayers in order to perform a statistical quantification of the sphere size,
mask opening size, and sphere-sphere separation distributions. Search algorithms
based on Fourier transformation, cross-correlation, multiple-angle intensity profiling,
and sphere edge point detection techniques allow for a sphere detection efficiency
of at least 99.8%, even in the case of considerable sphere size variations. While
the sphere positions and diameters are determined by fitting circles to the spheres
edge points, the openings between sphere triples are detected by intensity thresholding.
For the analyzed polystyrene sphere monolayers with sphere sizes between 220 and
600 nm and a diameter spread of around 3% coefficients of variation of 6.8–8.1%
for the opening size are found. By correlating the mentioned size distributions,
it is shown that, in this case, the dominant contribution to the opening size
variation stems from nanometer-scale positional variations of the spheres.

text: The development of renewable energies and smart mobility has profoundly
impacted the future of the distribution grid. An increasing bidirectional energy
flow stresses the assets of the distribution grid, especially medium voltage switchgear.
This calls for improved maintenance strategies to prevent critical failures. Predictive
maintenance, a maintenance strategy relying on current condition data of assets,
serves as a guideline. Novel sensors covering thermal, mechanical, and partial
discharge aspects of switchgear, enable continuous condition monitoring of some
of the most critical assets of the distribution grid. Combined with machine learning
algorithms, the demands put on the distribution grid by the energy and mobility
revolutions can be handled. In this paper, we review the current state-of-the-art
of all aspects of condition monitoring for medium voltage switchgear. Furthermore,
we present an approach to develop a predictive maintenance system based on novel
sensors and machine learning. We show how the existing medium voltage grid infrastructure
can adapt these new needs on an economic scale.

Abstract
The stagnation point heat fluxes of methane/air flames impinging normal on a cylindrical surface were determined experimentally. Light induced phosphorescence from thermographic phosphors was used to investigate surface temperatures at the stagnation point from a nearly 1D laminar premixed flame burning against a water-cooled ceramic tube. The ceramic tube was coated with 1.1% chromium-doped alumina (ruby) at the impingement area and excited with a green light-emitting diode (LED) to measure the surface temperature. The flame temperature profiles were also measured with a thermocouple of type R (Pt/Pt + 13% Rh). Effects on variations in cold gas velocity (0.1 m s−1–0.5 m s−1) relative to the flame speed, equivalence ratio (Ф = 0.85–1.2), burner to impingement surface spacing (H/d = 0.5–2) and surface curvature are reported. The stagnation point heat fluxes are strongly influenced by the flame stabilization mechanism, which changes from burner to wall stabilization, which also is seen from the measured flame temperature profiles. Increasing the cold gas velocity of the reactants leads to higher stagnation point heat fluxes. In addition, decreasing the distance between the burner and impingement surface increases the heat flux, with higher heat fluxes recorded for a tube compared to a flat plate.
