text: "Effect chain modelling is a method for creating information\r\nmodels for
impact analyses of changes in system elements. For\r\nthe estimation of change
propagation, dependencies between\r\nrequirements must be detected. The high number
of require-\r\nment dependencies in the engineering of complex technical\r\nsystems
results in the need for automation. In a study, it was\r\nshown that transformer
models (BERT) are suitable for the\r\nautomated dependency analysis of requirements.
However,\r\nthere are currently deficits in the applicability of the models\r\nfor
different projects without an extensive and heterogeneous\r\ntraining database.
This paper investigates how active learning\r\ncan be used to train BERT models
(active-BERT) in order to\r\nincrease the performance of the models for classifying
requi-\r\nrement dependencies of projects with heterogeneous require-\r\nments.
The results show that the performance of the models\r\nincreases significantly
through active learning. Through active-\r\nBERT, engineers are enabled to model
effect chains efficiently\r\nand to handle requirement changes effectively."

text: "\r\nPurpose\r\nThe
purpose of this study is to investigate the manufacturability of Fe-3Si lattice
structures and the resulting mechanical properties. This study could lead to the
successful processing of squirrel cage conductors (a lattice structure by design)
of an induction motor by additive manufacturing in the future.\r\n\r\n\r\nDesign/methodology/approach\r\nThe
compression behaviour of two lattice structures where struts are arranged in a
face-centred cubic position and vertical edges (FCCZ), and struts are placed at
body-centred cubic (BCC) positions, prepared by laser powder bed fusion (LPBF),
is explored. The experimental investigations are supported by finite element method
(FEM) simulations.\r\n\r\n\r\nFindings\r\nThe
FCCZ lattice structure presents a peak in the stress-strain curve, whereas the
BCC lattice structure manifests a plateau. The vertical struts aligned along the
compression direction lead to a significant increase in the load-carrying ability
of FCCZ lattice structures compared to BCC lattice structures. This results in
a peak in the stress-strain curve. However, the BCC lattice structure presents
the bending of struts with diagonal struts carrying the major loads with struts
near the faceplate receiving the least load. A high concentration of geometrically
necessary dislocations (GNDs) near the grain boundaries along cell formation is
observed in the microstructure.\r\n\r\n\r\nOriginality/value\r\nTo
the best of the authors’ knowledge, this is the first study on additive manufacturing
of Fe-3Si lattice structures. Currently, there are no investigations in the literature
on the manufacturability and mechanical properties of Fe-3Si lattice structures.\r\n"

text: Die Energieaufnahme von Haushaltskältegeräten ist seit den 1990er Jahren erheblich
gesunken. Dieser Wert wird von den Herstellern im Neuzustand der Geräte unter
Normbedingungen bestimmt. Wie jedes technische System unterliegen jedoch auch
Haushaltskältegeräte einem Alterungsprozess, der zu einem Anstieg der Energieaufnahme
über die Zeit führt. Im Rahmen dieser Dissertation wurde auf der Grundlage von
100 Messungen der Energieaufnahme, die an 32 Geräten über einen Zeitraum von 21
Jahren durchgeführt wurden, ein Alterungsmodell entwickelt. Dieses Modell ist
das erste, das mit Hilfe von Daten der Energieaufnahme real gealterter Geräte
entwickelt wurde. Es beschreibt einen Anstieg der Energieaufnahme von 27 % über
die durchschnittliche Einsatzzeit eines Haushaltskältegeräts von 16 Jahren. Der
stärkste Anstieg erfolgt in den ersten fünf Betriebsjahren. Durch Diffusionsvorgänge
in dem im Gehäuse verbauten Polyurethan-Schaum wird das im Zellgas vorhandene
Kohlenstoffdioxid durch Luft ersetzt. Hierdurch steigt die Wärmeleitfähigkeit
des Schaums um ca. 33 % an, wodurch sich die Energieaufnahme der Geräte erhöht.
Des Weiteren wurde der Einsatz von Paraffinen als Phasenwechselmaterial in Haushaltskältegeräten
untersucht. Durch deren Einsatz konnte die Energieaufnahme gesenkt und die Funktionalität
der Geräte gesteigert werden. Hierfür sind detaillierte Kenntnisse der Materialkenndaten
der Paraffine notwendig. Die Wärmeleitfähigkeit der verschiedenen Paraffin-Stoffgruppen
in der festen Phase ist jedoch bisher nur unzureichend untersucht worden. Daher
wurde ein Messaufbau entwickelt, mit dem die Wärmeleitfähigkeit von festem Paraffin
bestimmt werden kann, und es wurden entsprechende Messungen durchgeführt.

text: The energy consumption of household refrigeration appliances has decreased
significantly since the 1990s. This value is determined by the manufacturers under
standard conditions when the appliances are new. However, like any other technical
system, these appliances are also subject to an aging process that leads to an
increase of energy consumption over the time of usage. As part of this thesis,
an aging model was developed on the basis of 100 standard energy consumption measurements
carried out on 32 appliances over a period of 21 years. This model is the first
to be developed on the basis of energy consumption data from real aged appliances.
It describes an increase of energy consumption by 27 % over 16 years, which is
the average period of use of a household refrigeration appliance. The largest
increase occurs in the first five years of use. Diffusion processes in the polyurethane
foam installed in the cabinet of the appliances result in an exchange of carbon
dioxide with air. This gas exchange increases the thermal conductivity of the
foam by approximately 33 %, which rises the energy consumption of the appliances.
Furthermore, the use of paraffins, as one type of phase change materials, in household
refrigeration appliances was investigated. The use of these materials made it
possible to reduce energy consumption and increase the functionality of the appliances.
This application of paraffins requires detailed knowledge of their material characteristics.
However, the thermal conductivity of paraffins in the solid state has so far only
been investigated insufficiently. Therefore, a measurement setup for determining
the thermal conductivity of solid paraffins was developed and corresponding measurements
were carried out.

text: In this work, the influence of the filler–matrix adhesion on the tensile properties
of laser-sintered parts built with Polyamide 613 filled with glass beads was investigated.
For this purpose, dry blends of glass beads with and without organosilane coupling
agents and polyamide powder were prepared and processed into tensile specimens
on an EOS P396 laser sintering system. The samples were tested both in the dry
state and after an accelerated conditioning in a climate chamber. Furthermore,
finite element method (FEM) simulations were performed to model the extreme cases
of optimum adhesion and no adhesion. By correlating the tensile tests with the
simulation results and by analyzing the fracture surfaces, it was shown that the
filler–matrix adhesion is sufficient in the dry state but is strongly degraded
by conditioning. Even the presence of various organosilane thin films could not
prevent a strong deterioration of the filler–matrix adhesion and the associated
deterioration of the mechanical properties. Since a comparison with an injection-molded
sample of the same polymer filler combination shows identical behavior after conditioning,
it is assumed that this problem is not limited to additively manufactured parts.

text: In the laser sintering technology, the semi-crystalline polymer material is
exposed to elevated temperatures during processing, which leads to serious material
ageing for most materials. This has already been investigated intensively by various
authors. However, the ageing of the material at ambient temperatures during shelf
life has not been the focus so far. The need to analyse the shelf life can be
derived from an ecological and economic point of view. This work is focusing on
the shelf life of PA2200 (PA12). To reduce the potential influences of powder
production fluctuations, two different powder batches stored for 5.5 years and
6.5 years are investigated and compared to a reference powder produced 0.5 years
before these investigations. Multiple powder analyses and part characterisations
have been performed. A significant yellowing and molecular chain length reduction
can be derived from the measurement results. Whereas the influence on mechanical
part performance was minor, the parts built with the stored powders are more yellowish.
As it is most likely that this is due to the consumption of polyamide stabilisers,
it can be assumed that these parts will be subject to significantly faster ageing.
Therefore, it is still not recommended to use the stored powders for critical
parts or light intense and humid environments.
