text: We present a data acquisition and visualization pipeline that allows experts
to monitor additive manufacturing processes, in particular laser metal deposition
with wire (LMD-w) processes, in immersive virtual reality. Our virtual environment
consists of a digital shadow of the LMD-w production site enriched with additional
measurement data shown on both static as well as handheld virtual displays. Users
can explore the production site by enhanced teleportation capabilities that enable
them to change their scale as well as their elevation above the ground plane.
In an exploratory user study with 22 participants, we demonstrate that our system
is generally suitable for the supervision of LMD-w processes while generating
low task load and cybersickness. Therefore, it serves as a first promising step
towards the successful application of virtual reality technology in the comparatively
young field of additive manufacturing.

text: AbstractEngineering projects for complex
technical systems such as automobiles demand extensive requirement specifications
and corresponding hierarchy levels in system architectures. Especially when considering
emergent phenomena, such as total weight or aerodynamics, a closely networked
collaboration of discipline‐specific and cross‐disciplinary roles is required.
Further, in large organizations with a group structure, resulting functional and
non‐functional contents need to be managed by distinct Systems Engineering roles.
For example, the role “property manager” takes care of achieving overarching product
properties, such as weight or aerodynamics, which cannot be directly fixed, but
result from many specifications. This paper proposes new Systems Engineering roles
and their application in a German Original Equipment Manufacturer (OEM). For validation,
the roles have already been applied in everyday engineering projects at the OEM.
The concept proved to be indispensable and transferable to other Systems Engineering
projects.

text: AbstractTo investigate the point where inappropriate
defensive movements can no longer be inhibited and to validate suitable stimulus
material for constructing a basketball-specific anticipation-response-inhibition
task, two experiments were conducted. In Experiment 1, participants without basketball
expertise (N = 25) watched a video of a basketball jump shot and were asked to
release the space bar at the point when the ball leaves the player's fingertips
(go-trials). In 25% of all trials, the video was stopped prematurely and participants
should withhold their finger-lift response (stop-trials). A staircase-tracking
algorithm was used to adjust the point-in-time when the jump shot was stopped
in a way that participants’ inhibition rate was at 50% (reflecting the so called
“point-of-no-return”, PNR). In Experiment 2, the stimulus material was adapted
so that stop-trials simulated a pump fake. The PNR in Experiment 1 was located
187 ms and in Experiment 2 177 ms before the point of ball release. Precision
performance benefit from practice across blocks and participants delayed their
responses after stop-trials in a subsequent go-trial, which reflects strategic
post-stop-trial adjustments. Based on the comparable results of previous studies,
the given stimulus material is suitable for investigating response inhibition
skills in dynamic sport-specific environments.

text: Schülerlabore haben unter anderem zum Ziel, die Motivation, insbesondere das
Interesse – i.S. einer gegenstandsbezogenen Motivation – von Schüler*innen an
MINT-Themen und -Arbeitsweisen zu fördern. Darüber hinaus konnten sie sich schneller
und produktiver als die formalen Bildungsorte den Herausforderungen der digitalen
Transformation stellen. Das Potenzial, Schülerlabore auch als innovative Orte
der Lehrkräftefortbildung (LFB) zu nutzen und digitalisierungsbezogene Kompetenzen
bei Lehrkräften aufzubauen, wurde bisher nicht ausgeschöpft. Im Verbundprojekt
mit insgesamt acht Standorten werden Schülerlabore zu LFB-Labs-digital ausgebaut
und die Frage nach Implementierungsvoraussetzungen gelingender Fortbildungen in
der digitalen Welt im MINT-Bereich bearbeitet. In diesem Artikel werden die theoretische
Fundierung, Ziele und anvisierten Forschungsarbeiten des Verbunds LFB-Labs-digital
dargelegt. Zur Unterstützung der mit der forschungsbasierten Qualitätsentwicklung
der MINT-bezogenen Aus-, Fort- und Weiterbildung von Lehrkräften betrauten Einrichtungen
in den Ländern sollen in Kooperation mit dem Kompetenzzentrum MINT des Bundes
die Lernorte „Schülerlabore“ für die digitale LFB erschlossen werden, um vermittelt
hierüber die Motivation von Schüler*innen für die MINT-Fächer zu fördern. Die
in den Schülerlaboren evaluierten und vom fächerübergreifenden adaptiven Qualitätsmanagement
für die LFB wissenschaftlich begleiteten Good-Practice-Beispiele werden zur Grundlage
für den „Referenzrahmen LFB-Labs-digital“. Dieser wird – vor dem Hintergrund einer
Ergebnistriangulation aus der Begleitforschung sowie den damit parallelisierten
Studien zur Evidenzbasierung der Lehrkräftequalifizierung in der digitalen Welt
und dem Musterqualitätshandbuch LFB – entwickelt und von einem Implementierungsbeirat
mit ausgewiesenen Expert*innen in diesem Bereich auf Transferoptionen hin geprüft.
Die digitale Infrastruktur für die LFB-Labs-digital-Veranstaltungsformate wird
hierzu prozessbegleitend ausgebaut.

text: AbstractCold forming of polycarbonate films
results in the formation of shear bands in the necking zone. The numerical results
obtained from standard viscoplastic material models exhibit mesh size dependency,
requiring mathematical regularization. For this purpose, we present in this work
a large deformation gradient theory for a viscoplastic isotropic material model
published before. We extend our model to a micromorphic model by introducing a
new micromorphic variable as an additional degree of freedom along with its first
gradient. This variable represents a microequivalent plastic strain. The relation
between the macroequivalent plastic strain and the micromorphic variable is accomplished
by a micromorphic coupling modulus. This coupling forces proximity between the
macro- and microvariables, leading to the targeted regularization effect. The
micromorphic model is implemented as a three-dimensional initial boundary value
problem in an in-house finite element tool. The analysis is performed for both
uniaxial and biaxial specimens. The provided numerical examples show the ability
of our model to regularize shear bands within the specimens and address the issue
of localization.

text: Food labels are supposed to quickly inform consumers about the nutritional
values of products. We provide evidence that in a system where labels are voluntary,
they are systematically distorted. The probability of finding a label on a product
of the category with the highest nutritional value is 51 percentage points larger
than in the lowest category.

text: In today's digital world, data-driven digital artefacts pose challenges for
education, as many students lack an understanding of data and feel powerless when
interacting with them. This article addresses these challenges and introduces
the data awareness framework. It focuses on understanding data-driven technologies
and reflecting on the role of data in everyday life. The paper also presents an
empirical study on young school students' data awareness. The study involves a
teaching unit on data awareness framed by a pretest-posttest design using a questionnaire
on students' awareness and understanding of and reflection on data practices of
data-driven digital artefacts. The study's findings indicate that the data awareness
framework supports students in understanding data practices of data-driven digital
artefacts. The findings also suggest that the framework encourages students to
reflect on these data practices and think about their daily behaviour. Students
learn a model about interactions with data-driven digital artefacts and use it
to analyse data-driven applications. This approach appears to enable students
to understand these artefacts from everyday life and reflect on these interactions.
The work contributes to research on data and AI literacies and suggests a way
to support students in developing self-determination and agency during interactions
with data-driven digital artefacts.

text: "Approaches to modeling and evaluating teachers’ digital competencies are
often based on the TPACK model. However, in-depth analyses of the conceptualization
of the model show that the specificities of the so-called dual subject matter
of vocational education are not sufficiently represented. This article provides
insights into the development and testing of an instrument for teachers’ self-assessment
of digital competencies in vocational education.The instrument is based on the
structure of TPACK but is adapted in various ways to reflect the specificities
of vocational education. The aim of this article is to transfer a conceptual extension
oft he TPACK model into an initial instrument\r\nand to analyze it as part of
an initial exploration.\r\n"

text: AbstractMost FPGA boards in the HPC domain
are well-suited for parallel scaling because of the direct integration of versatile
and high-throughput network ports. However, the utilization of their network capabilities is
often challenging and error-prone because the whole network stack and communication
patterns have to be implemented and managed on the FPGAs. Also, this approach
conceptually involves a trade-off between the performance potential of improved
communication and the impact of resource consumption for communication infrastructure,
since the utilized resources on the FPGAs could otherwise be used for computations.
In this work, we investigate this trade-off, firstly, by using synthetic benchmarks
to evaluate the different configuration options of the communication framework
ACCL and their impact on communication latency and throughput. Finally, we use
our findings to implement a shallow water simulation whose scalability heavily
depends on low-latency communication. With a suitable configuration of ACCL, good
scaling behavior can be shown to all 48 FPGAs installed in the system. Overall,
the results show that the availability of inter-FPGA communication frameworks
as well as the configurability of framework and network stack are crucial to achieve
the best application performance with low latency communication.

text: 'The computation of electron repulsion integrals (ERIs) is a key component
for quantum chemical methods. The intensive computation and bandwidth demand for
ERI evaluation presents a significant challenge for quantum-mechanics-based atomistic
simulations with hybrid density functional theory: due to the tens of trillions
of ERI computations in each time step, practical applications are usually limited
to thousands of atoms. In this work, we propose SERI, a high-throughput streaming
accelerator for ERI computation on HBM-based FPGAs. In contrast to prior buffer-based
designs, SERI proposes a novel streaming architecture to address the on-chip buffer
limitation and the floorplanning challenge, and leverages the high-bandwidth memory
to overcome the bandwidth bottleneck in prior designs. Moreover, to meet the varying
computation, bandwidth, and floorplanning requirements between the 55 canonical
quartet classes in ERI calculation, we design an automation tool, together with
an accurate performance model, to automatically customize the architecture and
floorplanning strategy for each canonical quartet class to maximize their throughput.
Our performance evaluation on the AMD/Xilinx Alveo U280 FPGA board shows that,
SERI achieves an average speedup of 9.80 x over the previous best-performing FPGA
design, a 3.21x speedup over a 64-core AMD EPYC 7713 CPU, and a 15.64x speedup
over an Nvidia A40 GPU. It reaches a peak throughput of 23.8 GERIS ($10^9$ ERIs
per second) on one Alveo U280 FPGA. SERI will be released soon at https://github.com/SFU-HiAccel/SERI.'

text: AbstractA new control method aims at the
precise high dynamic control of the force signal for experimental vibration analysis,
which is generated by an electrodynamic shaker. A bending beam is used as a nonlinear
test object. A design and a surrogate model of the test rig are shown and parameterized
based on test rig measurements. The force control algorithm using input/output
linearisation is described and implemented in Matlab/Simulink for simulative validation
studies. Conclusions drawn from the mathematical description of the problem as
well as simulation results show that the design of the contact between shaker
and test object is crucial to achieve a high control bandwidth and at the same
time reduce the energy consumption of the shaker. This leads to the practical
application using a novel damping contact element. Finally, experimental test
rig results are presented which show a closed loop bandwidth of at least 250 Hz
for sinusoidal excitation signals.

text: The widespread adoption of ultra-high strength steels, due to their high bulk
resistivity, intensifies expulsion issues in resistance spot welding (RSW), deteriorating
both the spot weld and surface quality. This study presents a novel approach to
prevent expulsion by employing a preheating current. Through characteristic analysis
of joint formation under critical welding current, the importance of plastic material
encapsulation around the weld nugget (plastic shell) at high temperatures in preventing
expulsion is highlighted. To evaluate the effect of preheating on the plastic
shell and understand its mechanism in expulsion prevention, a two-dimensional
welding simulation model for dissimilar ultra-high strength steel joints was established.
The results showed that optimal preheating enhances the thickness of the plastic
shell, improving its ability to encapsulate the weld nugget during the primary
welding phase, thereby diminishing expulsion risks. Experimental validation confirmed
that by employing the optimal preheating current, the maximum nugget diameter
was enhanced to 9.42 mm, marking an increase of 13.4 % and extending the weldable
current range by 27.5 %. Under quasi-static cross-tensile loading, joints with
preheating demonstrated a 7.9 % enhancement in maximum load-bearing capacity compared
to joints without preheating, showing a reproducible and complete pull-out failure
mode within the heat-affected zone. This study offers a prevention method based
on underlying mechanisms, providing a new perspective for future research on welding
parameter optimization with the aim of expulsion prevention.
