text: While neural network quantization effectively reduces the cost of matrix multiplications,
aggressive quantization can expose non-matrix-multiply operations as significant
performance and resource bottlenecks on embedded systems. Addressing such bottlenecks
requires a comprehensive approach to tailoring the precision across operations
in the inference computation. To this end, we introduce scaled-integer range analysis
(SIRA), a static analysis technique employing interval arithmetic to determine
the range, scale, and bias for tensors in quantized neural networks. We show how
this information can be exploited to reduce the resource footprint of FPGA dataflow
neural network accelerators via tailored bitwidth adaptation for accumulators
and downstream operations, aggregation of scales and biases, and conversion of
consecutive elementwise operations to thresholding operations. We integrate SIRA-driven
optimizations into the open-source FINN framework, then evaluate their effectiveness
across a range of quantized neural network workloads and compare implementation
alternatives for non-matrix-multiply operations. We demonstrate an average reduction
of 17\% for LUTs, 66\% for DSPs, and 22\% for accumulator bitwidths with SIRA
optimizations, providing detailed benchmark analysis and analytical models to
guide the implementation style for non-matrix layers. Finally, we open-source
SIRA to facilitate community exploration of its benefits across various applications
and hardware platforms.

text: Abstract This study explores the usability and onboarding process of a Mixed
Reality (MR) application called PEARL, designed to prepare students for laboratory
work. Originally developed for mobile Augmented Reality (mAR), PEARL was adapted
for MR to offer a more immersive and intuitive experience through hand and gesture
controls. Since many students lack experience with MR devices, a user-friendly
onboarding system is essential. The study aims to redesign PEARL’s user interface
and onboarding experience, evaluating how intuitive interaction elements impact
usability. First, a literature review will identify existing usability guidelines
for MR applications, which will guide the redesign of the interface. This new
version will then be tested with students through a user study. Feedback will
be collected via an online survey to assess the onboarding and user experience,
and the findings will be used to refine the design further. The expected outcome
is an improved onboarding process and interface, making PEARL accessible even
for MR novices, enhancing their ability to interact with 3D objects in a real-world
setting. Ultimately, the study aims to provide best practices for developing intuitive
MR interfaces and effective onboarding experiences, especially in educational
contexts.

text: This chapter explores the crucial role of simulation and modelling of electronic
and photonic components for terahertz (THz) systems. THz-related challenges already
begin with setting up the signal generation and sampling parameters and continue
with the realistic modelling of the electronic and photonic building blocks. Hereby,
photonic components require not only the modelling of the optical signal propagation
but also the modelling of the electronic interface in the THz regime. Furthermore,
when advancing to the simulation of systems like fully integrated electronic transmit
and receive frontends or photonically assisted analogue-to-digital converters
(ADCs), it is up to the designer to find a suitable level of abstraction. Size,
complexity, and available computational power versus accuracy must be taken into
consideration and prioritized against each other.

text: "Das hochschuldidaktische Konzept des Forschenden Lernens gilt als zentrales
Element der universitären Lehrkräftebildung in Deutschland und ist in fast allen
Bundesländern Bestandteil des Praxissemesters. Damit einhergehende Erwartungen
im Hinblick auf den Professionalisierungsprozess von Lehrkräften fokussieren insbesondere
die Vermittlung einer forschenden Grundhaltung, die auf eine nicht-wissenschaftsferne
Berufsausübung abzielt. Wir fassen die forschende Grundhaltung als Professionsüberzeugung,
die aus einer kognitiven, affektiven und handlungsbezogenen Komponente besteht
und untersuchen die Komponenten im Zusammenspiel sowie im Längsschnitt.\r\n
\ Mittels teilstrukturierter Interviews mit 22 angehenden Lehrkräften
im Referendariat und Berufseinstieg, die sich im Praxissemester mit Forschendem
Lernen befasst haben, werden das Verständnis (kognitive Komponente) und die Bedeutsamkeit
(affektive und handlungsbezogene Komponente) Forschenden Lernens in der jeweiligen
Ausbildungs- bzw. Berufsphase erfragt. Die Daten werden inhaltsanalytisch sowie
typenbildend ausgewertet, um das Verständnis und die Bedeutsamkeit in der jeweiligen
Phase, längsschnittliche Entwicklungen sowie das Verhältnis von Verständnis und
Bedeutsamkeit herauszuarbeiten. Die Befunde zeigen, dass die Verständnisse von
Forschendem Lernen sowohl im Referendariat als auch im Berufseinstieg variieren.
Zudem ist das Konzept – laut Schilderungen der Befragten – durchaus bedeutsam
für ihre Lern- und Handlungspraxis, jedoch nicht für alle und in unterschiedlich
ausgeprägter Form. Die Typenbildung verdeutlicht, dass die fehlende Bedeutsamkeit
Forschenden Lernens mit Fehlkonzepten einhergeht und eine höhere Bedeutsamkeit
erkennbar ist, wenn Adaptionsleistungen hinsichtlich des Konzepts vorgenommen
werden. Insgesamt ist im Sinne der Auffassung als Professionsüberzeugung die Anbahnung
einer forschenden Grundhaltung bei einigen Befragten erkennbar. Implikationen
für eine künftige Hochschulbildung ergeben sich u. a. mit Blick auf die Unterstützung
von Studierenden bei Adaptionsleistungen für die (jeweilige) Praxis."

text: Simulation-based design of high-power ultrasonic systems depends on the accurate
modelling of the electromechanical behaviour of piezoceramic materials. In practical
transducer applications, the relevant operating points are influenced by mechanical
preload and heating, both of which give rise to changes in the elastic, dielectric,
and piezoelectric material properties. Material parameters identified under idealised,
unloaded conditions are therefore insufficient to represent piezoceramic material
behaviour under realistic operating conditions. To overcome this limitation, experimental
setups are developed that enable the measurement of electrical impedance spectra
under controlled thermal and mechanical conditions. The acquired impedance data
are used in an inverse identification procedure, in which the behaviour of a finite
element forward model is iteratively fitted to the measurements using a block
coordinate descent optimisation strategy guided by a sensitivity analysis. This
yields effective linear material parameters as a function of temperature and mechanical
stress at varying operating points. The identified temperature-dependent parameters,
for instance, can be employed in a coupled thermo-electromechanical simulation
framework to predict the temperature-dependent material behaviour during operation.
The linear identification based on varying operation points provides an initial
approximation of the nonlinear material response, establishing a basis for the
development of corresponding nonlinear material models.

text: Subject of this paper is the investigation of the influence of local
joint kinematics on the load-bearing and failure behavior of self- piercing riveted
(SPR) joints. It can be shown that the local joint kinematics of SPR joints correlate
with the failure mechanism of the joint. The kinematics are highly influenced
by the material properties of the joining partners. Detailed experimental results
from tensile tests on a representative SPR joint are presented, with local joint
kinematics quantified using multiple complementary measurement methods (optical
measurement, micrographs, in situ computer tomography). Furthermore, results of
component tests are shown where the kinematics of the joints have been measured
in the same manner. The experimental results are later used to calibrate simulation
models for crash application which are used to simulate the specimen and component
tests. The results of the investigation show that the local joint kinematic influences
the failure behavior of the joint. Simulations of the experimental tests have
shown good results, and the investigated models are able to predict the actual
joint behavior.

text: "The use of aluminium materials in the structural and bodywork areas of assemblies
has proven to be a targeted option for lightweight design. How-ever, the reliable
and cost-efficient joining of aluminium components remains a challenge. Mechanical
joining methods, such as riveting, are frequently used in the automotive and aerospace
construction industries. Rivets are made from heat-treated steels. Compared to
steel, the use of aluminium materials for fasten-ers offers several advantages
in terms of joining properties, particularly in terms of recyclability, corrosion
resistance and reduced weight of the joined structure. Additionally, the manufacturing
process is shorter since aluminium fasteners do not require coating. However,
aluminium rivets can often not be used due to the insufficient mechanical strength
of the fastener material in relation to the joining component materials.\r\nThis
study systematically investigates the requirements for using solid alu-minium
self-piercing rivets. The influence of rivet geometry adjustments on the joint
quality is analysed using numerical simulation. The results are used to derive
and evaluate an optimised rivet geometry for joining pure aluminium sheets. On
this basis, solid self-drilling rivets with optimised geometry are manufactured
from particle-reinforced aluminium produced in a continuous extrusion process
by machining. The integration of particles increases the material’s strength.
Exper-imental tests are conducted to evaluate the use of optimised solid self-piercing
rivets. The quality-relevant parameters are determined and evaluated based on
macrographs of the joints."

text: Expanding renewable energy sources is essential for a sustainable energy supply
but challenges grid stability, as the volatility of solar and wind causes periods
of over- and undersupply. Private households are central to this transition, combining
dynamic consumption with decentralised generation. This paper presents a multi-agent
microgrid simulation built on the Mesa framework, focusing on the heterogeneous
objectives and technological capabilities of residential participants. Households
are modelled as autonomous agents with individual strategies, while a dedicated
“grid agent” represents the distribution system operator and regulates the microgrid
in a grid-supportive manner. The emission factor serves as the key indicator for
grid-friendly behaviour. Results show that in summer, unmanaged PV feed-in from
heterogeneous households causes substantial grid stress and balancing effort for
the distribution system operator. Dynamic electricity prices can incentivise grid-friendly
dispatch, but their effectiveness depends on the correlation between price signals
and renewable availability and cannot guarantee grid-supportive behaviour alone.
The grid agent reliably improves the grid-supportive coefficient, yet its operating
strategy, for instance additional peak-reduction objectives, can interfere with
price-based incentives. Effective demand-side management therefore requires careful
analysis of stakeholder interactions. Building on this insight, thepaper provides
a basic framework for the design, implementation, and assessment of both integrated
and individual energy management strategies within a microgrid environment. By
simulating the dynamic interactions among system participants and strategies,
it enables comprehensive evaluation of their collective impact on the grid, supporting
the development of robust solutions for future electricity networks.

text: "ABSTRACT:\r\n Engineers
simulate system behavior to support decisions in product engineering. Leveraging
such engineering simulation data in strategic product planning can support idea
generation and early evaluation of design alternatives and limitations. However,
limited resources and expertise hinder broader uptake in strategic product planning.
This paper investigates simulator integration into automated workflows and key
processing components to enable simulation without in-depth expertise. This approach
improves strategic product planning by creating data-based decision support."

text: Resilient systems require monitoring and prediction of environmental and intrinsic
conditions and the ability to adapt to changing circumstances to optimize the
trade-off between performance, power consumption, and fault tolerance. TETRISC
was introduced as a resilient multicore RISC-V processor system based on the PULPissimo
platform. This paper presents the migration of TETRISC to the Rocket Chip SoC,
which is freely scalable to the number of processors through parametrizable Chisel
models. As such, we discuss and evaluate the main advantages and obstacles that
come with the Chipyard framework for RTL simulation and FPGA synthesis for the
rapid prototyping of resilient, scalable architectures that are online configurable
through software for different multicore and lock-step modes.

text: The key to achieving energy efficiency and reducing carbon emissions in transportation
lies in the effectiveness of vehicles and their associated mechatronic systems.
A notable example of a mechatronic system is the headlamp at the front of a vehicle,
which emits adaptive headlights, such as the well-known adaptive cornering lights
or glare-free high beam. The rise of these and other Advanced Driver Assistance
Systems (ADAS) has led to a proliferation of sensor data. However, the full potential
of ADAS sensor data for increasing energy efficiency has not yet been exploited
in the past. This study demonstrates that utilizing the data to dynamically adapt
headlights to the upcoming driving scenario leads to a substantial reduction in
power consumption. This objective is pursued by focusing on the predominant carbon
footprint driver, namely the low beam.

text: Manufacturing companies increasingly integrate the strive towards sustainability
into product engineering to reduce resource consumption and environmental impacts.
A substantial share of a product’s environmental performance is determined during
engineering. Early assessments rely on generic data, which is gradually replaced
by more concrete simulation and primary data as product maturity increases. The
effective use of engineering simulation models for Life Cycle Assessment (LCA)
therefore remains a central challenge under heterogeneous, distributed and rapidly
evolving data. This article presents a systematic review of product engineering
approaches for integrating simulation models into LCA. A seven-step research approach
is applied to identify, categorize and evaluate existing approaches across CAx
tools. Relevant simulation parameters for sustainability assessment, including
material properties, process descriptors, consumables and waste streams, are identified
and analyzed. Based on identified data characteristics, the potential of Data
Science and Artificial Intelligence methods for LCA data preparation is assessed.
A conceptual knowledge-graph-based decision support approach is derived to enable
structured integration, traceability and reuse of simulation data for sustainability
assessment. The approach is evaluated using criteria from literature. Structured
integration of simulation data improves early-stage data quality and supports
decision-making in sustainable product engineering.

text: Raman imaging, based on incoherent spontaneous Raman scattering (SR) or coherent
techniques such as broadband coherent anti-Stokes Raman spectroscopy (BCARS),
is a powerful tool for visualizing local lattice distortions. It can thus be employed,
e.g., to identify and visualize ferroelectric (FE) domain walls (DWs). While SR-based
DW imaging relies on small changes in the intensity or position of Raman peaks
at the DW, BCARS measurements may detect DW signatures with a drastically increased
contrast and orders of magnitude faster imaging speed. However, while SR-based
contrasts can be predicted from existing models, the increased DW contrasts in
BCARS remain poorly understood. In this work, we develop a first-principles approach
for the simulation of CARS spectra to investigate the origin of this BCARS signal
contrast at periodically poled stoichiometric lithium niobate (sPPLN) DWs. Combining
these atomistic simulations with strain modeling allows us to explore how strain
affects the CARS signal generation at FE DWs. We then apply polarization-sensitive
BCARS to image sPPLN DWs for different polarization configurations. Our results
reveal additional Raman peaks specific to the DWs across all investigated polarization
combinations, yielding a strong DW-to-bulk contrast that enables in situ identification
and localization of DWs in two-dimensional BCARS maps. This study demonstrates
the practical utility of polarization-sensitive BCARS for fast DW imaging and
provides fundamental insights into the BCARS contrast mechanism in FE materials,
both in strained regions and in the unstrained bulk.

text: "Germany is experiencing a shortage of teachers, a situation that is particularly
evident in the \r\ndomain of technical vocational education. In response to this,
various pathways into vocational \r\nteacher education have been established.
These pathways are diverse in their nature but all lead to \r\nthe same teacher
degree as traditional teacher education. In two interview studies (n=22 (pre\r\nservice)
vocational teachers), initial motives of entering teacher education (based on
FIT-Choice) \r\nas well as retrospective views on the career choice after entering
the profession (based on PLP\r\nmodel) are analyzed. The present study compares
the reflective views of pre-service teachers and \r\ncareer-changing in-service
teachers (CCIT). Although both groups generally perceive their career \r\nchoice
positively, the results raise questions about why CCITs did not enter the field
of teacher \r\neducation in the first place. Additionally, the analysis allows
for further discussion about existing \r\nteacher education programs in times
of teacher shortage."

text: Three‐dimensional (3D) assemblies of gold nanoparticles (AuNPs) offer a rich
platform for plasmonic coupling and near‐field engineering, yet their optical
behavior is often complex due to structural disorder and fabrication‐induced variability.
Here, we present a systematic optical investigation of large‐scale 3D AuNP assemblies
fabricated via meniscus‐guided assembly, focusing on the reproducibility, spatial
uniformity, and mode evolution of their plasmonic responses. Spatially‐resolved
dark‐field scattering measurements reveal that high‐aspect‐ratio AuNP pillars
exhibit uniform scattering spectra along their height and across different pillars,
despite variations in geometry and structure. Electromagnetic simulations suggest
that this robustness arises from a collective many‐particle plasmonic response
that remains optically active despite structural perturbations. The corresponding
near‐field and surface‐charge distributions remain spatially distributed under
representative structural perturbations, consistent with volumetric averaging
across the three‐dimensional assembly. Building on this robust platform, we introduce
compositional modulation through a core–satellite architecture by incorporating
smaller AuNPs. This yields a composition‐dependent spectral redistribution, including
the emergence of an additional long‐wavelength spectral feature in the core–satellite
assemblies. Wavelength‐dependent surface‐enhanced Raman scattering measurements
reveal contrasting responses under 633 and 785 nm excitation, reflecting redistribution
of local plasmonic coupling pathways. These results provide process‐enabled guidelines
for using meniscus‐guided 3D‐nanoprinting to realize robust nanoparticle assemblies.
