text: Modern industrial development has necessitated a wide range of joining technologies.
Self-pierce riveting has become a prevalent technique for sheet metal assembly,
especially in automotive applications. Achieving proper joint geometry and adequate
load-bearing capacity depends on appropriate tool selection and precise process
control. Material properties and condition also play a significant role in process
performance. To accommodate the inevitable variations in component characteristics
during production, a robust and stable joining process is essential. The study
focuses on investigating the influence of preformed joining partners on the joining
process and the joint's load capacity. An EN AW-6014 in T4 condition, as well
as an HCT590X, are used as materials for this study. For this purpose, an exemplary
process chain consisting of the steps of performing, joining, and shear load testing
is studied. Each process step is implemented using an FE model to predict the
outcome of subsequent steps. For analysis of the influence of pre-strain, an optimisation
software is used to plan and execute variations of the process. These variations
are used to create a meta-model that can describe the relationships between pre-forming
and characteristic parameters of subsequent process steps. The resulting model
is validated by comparing simulation and experimental data. Finally, in a novel
approach, the robustness of the presented process chain is analyzed in terms of
a tolerable performance level for the joining partners.

text: Utilizing data is crucial for economic success, but a lack of interoperability
and concerns about the misuse of ones own data are hindering the cross-organizational
use of data. Dataspaces provide the infrastructure necessary to integrate heterogeneous
data sources within an organization or ecosystem, enabling seamless data interaction
and interoperability. In addition, data spaces strengthen data sovereignty through
their decentralized nature, which enables organizations to effectively control
and manage their data. However, challenges persist in managing the complexity
and dynamic nature of dataspaces, requiring significant resources and technical
expertise. The decentralized nature leads to a large and diverse number of stakeholders,
who need to agree on the use and scope of a dataspace. Modeling is a common approach
to cope with technical complexity and heterogeneous stakeholders. In this paper,
we propose a version of SysML and a corresponding method that focus on the modelling
of data spaces. We provide a dataspace modelling method to unify the understanding
of dataspaces and scope among all stakeholders to simplify the design and development
process.

text: Verification and Validation (V&V) are essential processes in engineering Cyber-Physical
Systems. However, the role of V&V engineers is often not given sufficient attention.
Based on a systematic literature analysis and practical observations, a four-step
method for Test-oriented Resilient Requirements Engineering (ToRRE) is developed.
The steps are planning V&V, executing V&V activities, documenting V&V activities
and analyzing results of V&V activities. Applying ToRRE ensures continuous information
flow and traceability. Engineers are enabled to analyze requirements using engineering
artifacts connected through Model-Based Systems Engineering. Adopting methods
for Model-Based Effect Chain analysis to evaluated test cases and test scenarios,
conclusions on requirements engineering and change management are enabled. The
method is evaluated in an EU research project.

text: Augmented (AR) and Virtual Reality (VR) technologies have been applied very
broadly in the recent past. While prior work emphasizes the potential of these
technologies in various application domains, the process of visual attention in
and across the contexts of AR/VR environments is not exhaustively explored yet.
By now, visual attention in AR/VR environments has majorly been studied by means
of overt attention (i.e. saccadic eye movements), self-report, and process-related
visual attention proxies (like reaction time). In this work, we analyze covert
visual attention based on the (psychological) Theory of Visual Attention (TVA),
which allows us to quantify theory-based interpretable properties of the visual
attention process. For example, the TVA allows us to measure the overall processing
speed. We instantiate this TVA-based framework with a 30-participant explorative
within-subjects study. The results show a decisive difference in visual attention
between Reality (i.e. the neutral condition) and Virtual Reality and a weak difference
between Reality and Augmented Reality. We discuss the consequences of our findings
and provide ideas for future studies.

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.

text: "Nowadays, clinching is a widely used joining technique, where sheets are
joined by pure deformation to create an interlock without the need for auxiliary
parts. This leads to advantages such as reduced joining time and manufacturing\r\ncosts.
On the other hand, the joint strength solely relies on directed material deformation,
which renders an accurate material modelling essential to reliably predict the
joint forming. The formation of the joint locally involves large plastic strains
and possibly complex non-proportional loading paths, as typical of many metal
forming applications. Consequently, a finite plasticity formulation is utilised
incorporating a Chaboche–Rousselier kinematic hardening law to capture the Bauschinger
effect. Material parameters are identified from tension–compression tests on miniature
spec-\r\nimens for the dual-phase steel HCT590X. The resulting material model
is implemented in LS-Dyna to study the locally diverse loading paths and give
a quantitative statement on the importance of kinematic hardening for clinching.
It turns out that the Bauschinger effect mainly affects the springback of the
sheets and has a smaller effect on the joint forming itself."

text: The construct of noticing is considered to be of crucial importance for professional
action of (prospective) physical education (PE) teachers in the context of (inclusive)
PE. In order to implement the demands of inclusive PE teaching, noticingwith regard
to processes of recognition proves to be particularly significant. Due to the
relevance of physicality, the design of recognition relationships that encourage
pupils' development results in specific requirements for the selective attention
and the theory-based interpretation of processes of recognition and disregard
in complex teaching situations. This facet of competence has hardly been studied
so far, partly due to the lack of instruments for standardised assessment of this
construct. In the context of this paper, the development and validation of a standardised,
video vignette-based test instrument for the measurement of noticingwith regard
to processes of recognition of prospective PE teachers is presented. The validation
focuses on the content of the test and the internal structure of the instrument
as well as on correlations with related constructs in terms of content. The results
from three consecutive validation studies provide indications of the reliability
and validity of the test score interpretation of the instrument ViProQiS_A. The
findings so far indicate that the standardised measurement of noticingwith regard
to processes of recognitionin inclusive PE could be realized on the basis of the
test instrument developed here.

text: In control design most control strategies are model-based and require accurate
models to be applied successfully. Due to simplifications and the model-reality-gap
physics-derived models frequently exhibit deviations from real-world-systems.
Likewise, purely data-driven methods often do not generalise well enough and may
violate physical laws. Recently Physics-Guided Neural Networks (PGNN) and physics-inspired
loss functions separately have shown promising results to conquer these drawbacks.
In this contribution we extend existing methods towards the identification of
non-autonomous systems and propose a combined approach PGNN-L, which uses a PGNN
and a physics-inspired loss term (-L) to successfully identify the system's dynamics,
while maintaining the consistency with physical laws. The proposed method is demonstrated
on two real-world nonlinear systems and outperforms existing techniques regarding
complexity and reliability.

text: Within this work, we investigate how data-driven numerical approximation methods
of the Koopman operator can be used in practical control engineering applications.
We refer to the method Extended Dynamic Mode Decomposition (EDMD), which approximates
a nonlinear dynamical system as a linear model. This makes the method ideal for
control engineering applications, because a linear system description is often
assumed for this purpose. Using academic examples, we simulatively analyze the
prediction performance of the learned EDMD models and show how relevant system
properties like stability, controllability, and observability are reflected by
the EDMD model, which is a critical requirement for a successful control design
process. Subsequently, we present our experimental results on a mechatronic test
bench and evaluate the applicability to the control engineering design process.
As a result, the investigated methods are suitable as a low-effort alternative
for the design steps of model building and adaptation in the classical model-based
controller design method.

text: The integrated modeling of behavior and reliability in system development
delivers a model-based approach for reliability investigation by taking into account
the dynamic system behavior as well as the system architecture at different phases
of the development process. This approach features an automated synthesis of a
reliability model out of a behavior model enabling for the closed loop modeling
of degradation of the system and its (dynamic) behavior. The approach is integrated
into the development process following Systems Engineering. It is based on standard
models used in model-based development methodologies i.e. SysML or Matlab/Simulink.
In addition to the theoretical description of the necessary steps the procedure
is validated by an application example at two stages of the development process.

text: "Today, mobile and embedded real-time systems have to cope with the migration\r\nand
allocation of multiple software tasks running on top of a real-time operating\r\nsystem
(RTOS) residing on one or several system processors. Each RTOS has to\r\nbe configured
towards the individual needs of the application and environment.\r\nFor this,
different scheduling strategies and task priorities have to be evaluated in\r\norder
to keep execution and response times for a given task set. Abstract RTOS\r\nsimulation
is applied to analyze different parameters in early design phases. This\r\nchapter
presents a SystemC RTOS library for abstract yet accurate RTOS sim-\r\nulation,
supporting modeling of preemption in the presence of prioritized and\r\nnested
interrupts. After introducing basic principles of abstract RTOS simula-\r\ntion,
we present our SystemC library in detail. Thereafter, we discuss related\r\napproaches
and close with applications in electronic automotive systems design\r\nand some
evaluations."

text: UML has been widely accepted by the software community for several years.
As electronic systems design can no longer be seen as an isolated hardware design
activity, UML becomes of significant interest as a unification language for systems
description combining both HW and SW components. This article provides a comprehensive
view of the UML applied to System-on-Chip (SoC) and hardware-related embedded
systems design. The modeling concepts in the UML language are first introduced,
including major diagrams for the representation of the behavior and the structure
of systems. The principles behind application specific UML customizations (UML
profiles) are summarized, and several examples relevant for SoC design are given,
such as the SysML (System Modeling Language) and the SoC Profile. Thereafter,
various approaches associating UML with existing HW/SW design languages are presented.
Beyond language aspects, the article addresses the question of UML-based design
flows, and shows how UML can be applied concretely to the development of electronic-based
systems. The current situation about tool support constitutes the last focus of
the article. In particular, we show how UML tools can be combined with well-known
simulation environments, such as MATLAB.
