text: Abstract. Lightweight design is one of the central topics of the automotive
industry since reducing mass can save emissions over the entire life cycle of
a component. Nowadays, vehicle structures usually consist of a multi-material
design, which poses the additional challenge of joining these different materials.
Mechanical joining is the most common way of joining different types of materials.
Cast aluminium alloys of the AlSi system have a low ductility, which causes cracks
during the mechanical joining process in the joint. One research approach is to
achieve a fine microstructure by influencing the solidification rate since this
results in increased mechanical properties, specifically the elongation at fracture
and yield strength. A very fine microstructure can be achieved by utilizing Twin-roll
casting (TRC) which is a continuous casting process in which high solidification
rates of more than 100 K/s occur. In this study, the hypoeutectic cast aluminium
alloy AlSi9 is processed in the TRC process using copper rollers. The cast strips
are investigated regarding the microstructure-property correlation. A variation
of the roller materials and cooling conditions allows for an increase in the solidification
rate, whereby a defined, fine microstructure can be achieved, which enhances the
mechanical properties of the hypoeutectic aluminium casting alloys.

text: Abstract. Twin-Roll-Casting (TRC) is an energy- and cost-efficient
process to produce near-net-shape aluminum strips. Due to the high affinity of
molten aluminum to steel surfaces, those rollers show signs of wear throughout
the rolling campaign. This leads to the necessity of restoring the worn surfaces
to suitable parameters. The easiest way is to grind the surface till all superficial
defects are omitted. However, the thickness of the roller is not endless, therefore
the rollers must be replaced after a certain amount of surface reconditioning.
This ultimately leads to the non-usability of the roller. This research shows
a route to recondition the surface including the possibility of renewing worn-down
surfaces with an energy- and cost-efficient high-velocity oxygen fuel (HVOF) treatment
with subsequent grinding to the desired initial surface parameters.

text: In the face of climate change and growing sustainability awareness, industrial
companies are at a pivotal point in transforming from a linear to a circular economy
(CE) model. Yet, aligning their business with the principles of the CE is a challenging
task. Utilizing a systematic literature review (SLR) and thematic analysis a framework
for the business transformation towards the CE has been developed. It considers
the dimensions product, business strategy, corporate management, and value chain.
The circular business transformation (CBT) framework includes incentives for entering
the CE, fields of action, design options, and associated challenges. For researchers,
it provides a comprehensive overview and serves as a basis for in-depth studies
of each dimension of CBT. Furthermore, it acts as a practical guide that enables
industrial companies to strategically navigate through the complexity of the CBT
and to effectively design it.

text: Stress plays a crucial role in thin films and layered systems, and thus significantly
influences the material's electrical, mechanical and (nonlinear) optical responses.
Despite lithium niobate's wide applicability as a nonlinear optical material,
the impact of mechanical stress on its nonlinear optical properties is not well
characterized. In this work, we systematically study both experimentally and theoretically,
the nonlinear optical responses of thin film lithium niobate (TFLN) single crystals.
Compressive and tensile stress is applied in our experiment using a piezodriven
strain cell. We then record the second-harmonic-generated (SHG) response in back-reflection
geometry, and compare these results to theoretical modeling using density functional
theory (DFT). Both methods consistently reveal that uniaxial stress induces changes
of the nonlinear optical susceptibility of certain tensor elements on the order
of up to 1 pm/(V GPa). The exact value depends on the tensor element that is addressed
in our SHG analysis, on the crystal orientation, and also whether using compressive
or tensile stresses. Furthermore, a lowering of the crystal symmetry when applying
stress along the x
or y
crystallographic axes is observed by the appearance of new nonlinear optical tensor
elements within the strained crystals.

text: Fähigkeiten zur Wahrnehmung und Regulation von Emotionen sind von
besonderer Relevanz für Studierende, da Fördermaßnahmen im Bereich der Emotionsregulation
auch positive Effekte auf die Studienqualität, den Studienerfolg und die allgemeine
Persönlichkeitsentwicklung haben können. Jedoch wird diesem Thema wenig Aufmerksamkeit
geschenkt und hochschuldidaktisch steht die Gestaltung von kognitiven und inhaltsbezogenen
Lernarrangements im Zentrum. Die Einbindung von Gelegenheiten zur Emotionsreflexion
in die Lehre bietet eine niederschwellige Maßnahme zur Förderung emotionaler Kompetenzen,
weshalb im vorliegenden Beitrag ein Instrument zur Umsetzung dieser Aufgabe vorgeschlagen
wird.

text: The constantly increasing demand for climate protection and resource conservation
requires innovative and versatile joining processes that improve adaptability
to the joining task and robustness to enable flexible manufacturing on a production
line. Therefore, the versatile SPR (V-SPR) and tumbling SPR (T-SPR) were developed.
Using the example of a mixed material combination HCT590X+Z (t0 = 1.0 mm) / EN
AW-6014 T4 (t0 = 2.0 mm), these processes were examined and compared with regard
to the binding mechanisms form closure and force closure using micrographs, non-destructive
resistance measurements and destructive torsion tests. For this purpose, a new
sample geometry was defined, and the methods were adapted to the SPR process variants.

text: Conventional mechanical joining processes are typically rigid in their tool
systems and can only react to changing process and disturbance variables to a
limited extent. At the same time, various industries are increasingly trending
towards multi-material systems consisting of parts with varying geometric and
mechanical properties. Due to the varying properties, rigid mechanical joining
processes require sampling procedures and periodic changes of tool components
or auxiliary joining parts. Consequently, research is focusing on versatile mechanical
joining processes that allow increased control by modifying the process parameters.
Two processes based on self-piercing riveting can achieve a significant increase
in process influence possibilities through a multi-linear actuator as versatile
self-piercing riveting (V-SPR) and a tumbling superimposed actuator as tumbling
self-piercing riveting (T-SPR). Initial research into V-SPR has shown that this
process can be used to achieve a higher variation in overall package thickness
by adapting the rivet geometry and using multiple linear actuators. The T-SPR
process also enables increased material flow control by means of targeted compression
of the rivet using the tumbling actuator, thereby extending the range of joints
that can be manufactured. Based on these two processes, a combination of the two
mechanisms of action is to be developed.

text: Abstract. Mechanical joints are traditionally analyzed through destructive
micrograph analysis, which may compromise internal geometry and morphology, as
evidenced by radial cracks in semi-tubular self-pierce riveting. In contrast,
industrial X-ray computed tomography (XCT) offers a non-destructive method for
component diagnosis, providing volumetric insights without damaging the sample
and enabling dimensional measurement. The DFG-funded Collaborative Research Center
TRR 285 is exploring XCT's application in assessing mechanical joinability across
various joining processes and materials, particularly in multi-material systems
like steel-aluminum joints. XCT faces challenges in accurately capturing multi-material
compositions, leading to artifacts that complicate interface detection. This research
aims to validate XCT for joint investigations, yielding quantitative characteristics
that surpass those from traditional micrograph analysis.

text: The article introduces a method to learn dynamical systems that are governed
by Euler–Lagrange equations from data. The method is based on Gaussian process
regression and identifies continuous or discrete Lagrangians and is, therefore,
structure preserving by design. A rigorous proof of convergence as the distance
between observation data points converges to zero and lower bounds for convergence
rates are provided. Next to convergence guarantees, the method allows for quantification
of model uncertainty, which can provide a basis of adaptive sampling techniques.
We provide efficient uncertainty quantification of any observable that is linear
in the Lagrangian, including of Hamiltonian functions (energy) and symplectic
structures, which is of interest in the context of system identification. The
article overcomes major practical and theoretical difficulties related to the
ill-posedness of the identification task of (discrete) Lagrangians through a careful
design of geometric regularisation strategies and through an exploit of a relation
to convex minimisation problems in reproducing kernel Hilbert spaces.

text: Pillow-plate heat exchangers (PPHEs) represent a viable alternative to conventional
shell-and-tube and plate heat exchangers. The waviness of their channels intensifies
fluid mixing in the boundary layers and facilitates heat transfer. Applying secondary
surface structuring can further enhance the overall thermo-hydraulic performance
of PPHEs, thus increasing their competitiveness against conventional heat exchangers.
In this work, streamlined secondary structures applied on the PPHE surface were
studied numerically to explore their potential in enhancing near-wall fluid mixing.
Computational fluid dynamics (CFD) simulations of single-phase turbulent flow
in the inner PPHE channel were performed and pressure drop, heat transfer coefficients,
and overall thermo-hydraulic efficiency were determined. The simulation results
clearly demonstrate a favourable influence of secondary structuring on the heat
transfer performance of PPHEs.

text: Heat pumps play a crucial role in decarbonizing the chemical industry. The
integration and sizing of heat pumps in chemical processes is a challenging task
in multi-product chemical processes due to the fluctuating waste heat supply and
heat demand. Integrating heat pumps may require a retrofit of the utility system.
Mathematical optimization is a useful tool to tackle this challenge by enabling
the analysis of correlation between relevant system parameters and equipment sizing.
This study demonstrates the utilization of mathematical optimization and parameter
studies for utility system equipment sizing addressing fluctuating heat supply
and demand profiles.

text: Despite the advantages that the virtual knowledge graph paradigm has brought
to many application domains, state-of-the-art systems still do not support popular
graph database management systems like Neo4j. Their query rewriting algorithms
focus on languages like conjunctive queries and their unions, which were developed
for relational data and are poorly suited for graph data. Moreover, they also
limit the expressiveness of the ontology languages that admit rewritings, restricting
them to those that enjoy the so-called FO-rewritability property. Rewritings have
thus focused on the DL-Lite family of Description Logics. In this paper, we propose
a technique for rewriting a family of navigational queries for a suitably tailored
fragment of ELHI. Leveraging navigational features in the target query language,
we can include some widely-used axiom shapes not supported by DL-Lite. We implemented
a proof-of-concept prototype that rewrites into Cypher queries, and tested it
on a real-world cognitive neuroscience use case with promising results.

text: While existing studies have extensively explored various facets of international
students’ experiences, a gap remains in understanding the connection between their
social capital accumulation and information-seeking practices that shape the incoming
students’ extended transition process. Successful information-seeking is not solely
related to academic outcome; it is also influenced by the social capital resources
available within and beyond familiar cultural groups. This article sheds light
on how international students’ social capital accumulation shapes their information
searches across various online and offline social networks. A total of ten international
students were interviewed at the beginning and the end of their first semester
in Germany during the 2022–23 academic year. The findings demonstrate that the
incoming students’ information-seeking strategies and social capital accumulation
change over time. The students rely on their previously established social connections
offline and online when preparing for their departure. Upon arrival in Germany,
the students continue to search for information within their linguistic and cultural
familiar groups, but their information-seeking process shifts to local in-person
contexts. During the semester, lecturers and fellow students become useful information
sources at the university while the students develop confidence in their foreign
language skills.
