text: Many-body perturbation theory based on density-functional theory calculations
is used to determine the quasiparticle band structures and the dielectric functions
of the isomorphic ferroelectrics rubidium titanyl phosphate (RbTiOPO4) and potassium
titanyl arsenide (KTiOAsO4). Self-energy corrections of more than 2 eV are found
to widen the transport band gaps of both materials considerably to 5.3 and 5.2
eV, respectively. At the same time, both materials are characterized by strong
exciton binding energies of 1.4 and 1.5 eV, respectively. The solution of the
Bethe-Salpeter equation based on the quasiparticle energies results in onsets
of the optical absorption within the range of the measured data.

text: Wood–plastic composites (WPC) are enjoying a steady increase in popularity.
In addition to the extrusion of decking boards, the material is also used increasingly
in injection molding. Depending on the formulation, geometry and process parameters,
WPC tends to exhibit irregular filling behavior, similar to the processing of
thermosets. In this work, the influence of matrix material and wood fiber content
on the flow, mold filling and segregation behavior of WPC is analyzed. For this
purpose, investigations were carried out on a flow spiral and a sheet cavity.
WPC based on thermoplastic polyurethane (TPU) achieves significantly higher flow
path lengths at a wood mass content of 30% than polypropylene (PP)-based WPC.
The opposite behavior occurs at higher wood contents due to the different shear
thinning behavior. Slightly decreased wood contents could be observed at the beginning
of the flow path and greatly increased wood contents at the end of the flow path,
compared to the starting material. When using the plate cavity, flow anomalies
in the form of free jets occur as a function of the wood content, with TPU exhibiting
the more critical behavior. The flow front is frayed, but in contrast to the flow
spiral, no significant wood accumulation could be detected due to the shorter
flow path lengths.

text: Al-Li-based alloys are an attractive material for aircraft and aerospace applications.
Preparation of these alloys by twin-roll casting (TRC), which combines rapid metal
solidification and subsequent plastic reduction in a single processing step, could
improve the properties of the alloys compared to materials prepared by conventional
direct-chill casting. A commonly used approach for identifying primary phases
is a chemical analysis by energy dispersive spectroscopy (EDS). More accurate
results can be achieved by combining the method with diffraction analysis. This
process can be considerably simplified in microscopes equipped with automated
crystal orientation and phase mapping (ACOM-TEM). Al-Cu-Li-Mg-Zr alloy was prepared
by twin-roll casting. A combination of TEM and STEM images with chemical analysis
by EDS and ACOM-TEM was used to obtain complex information about phases of boundary
primary particles. The efficiency of the individual methods for the phase identification
in TRC Al-Li-based alloys is discussed.

text: "AbstractWith an innovative optical characterization
method, using high-temperature digital image correlation in combination with thermal
imaging, the local change in strain and change in temperature could be determined
during thermo-mechanical treatment of flat steel specimens. With data obtained
by this optical method, the transformation kinetics for every area of interest
along the whole measuring length of a flat specimen could be analyzed by the generation
of dilatation curves. The benefit of this innovative optical characterization
method compared to a dilatometer test is that the experimental effort for the
design of a tailored component could be strongly reduced to the investigation
of only a few tailored thermo-mechanical processed specimens. Due to the implementation
of a strain and/or temperature gradient within the flat specimen, less metallographic
samples are prepared for hardness analysis and analysis of the microstructural
composition by scanning electron microscopy to investigate the influence of different
process parameters. Compared to performed dilatometer tests in this study, the
optical method obtained comparable results for the transformation start and end
temperatures. For the final design of a part with tailored properties, the optical
method is suitable for a time-efficient material characterization.\r\n

text: In biomedical engineering, laser powder bed fusion is an advanced manufacturing
technology, which enables, for example, the production of patient-customized implants
with complex geometries. Ti-6Al-7Nb shows promising improvements, especially regarding
biocompatibility, compared with other titanium alloys. The biocompatible features
are investigated employing cytocompatibility and antibacterial examinations on
Al2O3-blasted and untreated surfaces. The mechanical properties of additively
manufactured Ti-6Al-7Nb are evaluated in as-built and heat-treated conditions.
Recrystallization annealing (925 °C for 4 h), β annealing (1050 °C for 2 h), as
well as stress relieving (600 °C for 4 h) are applied. For microstructural investigation,
scanning and transmission electron microscopy are performed. The different microstructures
and the mechanical properties are compared. Mechanical behavior is determined
based on quasi-static tensile tests and strain-controlled low cycle fatigue tests
with total strain amplitudes εA of 0.35%, 0.5%, and 0.8%. The as-built and stress-relieved
conditions meet the mechanical demands for the tensile properties of the international
standard ISO 5832-11. Based on the Coffin–Manson–Basquin relation, fatigue strength
and ductility coefficients, as well as exponents, are determined to examine fatigue
life for the different conditions. The stress-relieved condition exhibits, overall,
the best properties regarding monotonic tensile and cyclic fatigue behavior.

text: The components of a body in white consist of many individual thin-walled sheet
metal parts, which usually are manufactured in deep-drawing processes. In general,
the conditions in a deep-drawing process change due to changing tribology conditions,
varying degrees of spring back, or scattering material properties in the sheet
blanks, which affects the resulting pre-strain. Mechanical joining processes,
especially clinching, are influenced by these process-related pre-strains. The
final geometric shape of a clinched joint is affected to a significant level by
the prior material deformation when joining with constant process parameters.
That leads to a change in the stiffness and force transmission in the clinched
joint due to the different geometric dimensions, such as interlock, neck thickness
and bottom thickness, which directly affect the load bearing capacity. Here, the
influence of the pre-straining in the deep drawing process on the force distribution
in clinch points in an automotive assembly is investigated by finite-element models
numerically. In further studies, the results are implemented in an optimization
tool for designing clinched components. The methodology starts with a pre-straining
of metal sheets. This step is followed by 2D rotationally symmetric forming simulations
of the joining process. The resulting mesh of each forming simulation is rotated
and 3D models are obtained. The clinched joint solid model with pre-strains is
used further to determine the joint stiffnesses. With the simulation of the same
test set-up with an equivalent point-connector model, the equivalent stiffness
for each pre-strain combination is determined. Simulations are performed on a
clinched component to assess the influence of pre-strain and sheet thinning on
the clinched joint loadings by using the equivalent stiffnesses. The investigations
clearly show that for the selected component, the loadings at the clinch points
are dependent on the sheet thinning and the stiffnesses due to pre-strain. The
magnitude of the influence varies depending on the quantity considered. For example,
the shear force is more sensitive to the joint stiffness than to the sheet thinning.

text: By monitoring the recoating process within polymer laser sintering production,
it was shown that multiple powder-spread-flaws can be detected. Those groove-like
flaws are expected to be the result of agglomerates jamming between the recoater
and the last powder layer. This work is analyzing the interaction between powder-spread-flaws
and part properties, showing the influence of the recoating process on the performance
of laser sintering parts. Therefore, artificial powder-spread-flaws are applied
to the build jobs of tensile test specimens which are measured and analyzed regarding
the elongation at break, strength and fracture position. For the characteristics
of the flaws, the artificial grooves are varied in depth and width. Furthermore,
the position of the flaw is changed form mid part to close to surface areas. It
was shown, that several flaws are visible at the part surface, resulting in stress
concentration and reduced performance. But there are as well parts with flaw-layers,
which are not visible after the build process on the part. Those parts can have
significantly reduced mechanical properties as well.

text: "Die Anforderungen an die Entwicklung mechatronischer Systeme sind seit der
Erstfassung der VDI Richtlinie 2206 im Jahr 2004 stetig gestiegen. Nach einer
umfassenden Überarbeitung ist 2021 die Richtline im Weißdruck neu veröffentlicht
worden. Neben dem Systemdenken als gestärktes Kernelement des V-Modells und sechs
Kontrollpunkten nur Gliederung der sachlogischen Aufgaben ist die durchgängig
explizite „Modellierung und Analyse“ eine wesentliche Neuerung der Richtlinie.
Da sich die Kontrollfragen nur auf den Entwicklungsprozess im Ganzen beziehen,
wird durch die Betrachtung der Modellierung eines Batteriesystems aus einem Entwicklungsprojekt
eines deutschen Automobilherstellers die folgende Forschungsfrage betrachtet:
Welche spezifischen Kontrollfragen zu Fortschritt und Reifegrad der Modellierung
eines Batteriesystems können aus den Kontrollpunkten des V-Modells (VDI 2206:2020)
gefolgert werden?\r\nAls Ergebnis der Forschung liegen hinsichtlich der Modellierung
eines spezifischen Systems detaillierte Kontrollfragen vor, die eine methodische
Unterstützung für die modellbasierte Systementwicklung komplexer mechatronischer
Systeme bieten. Zusätzlich ermöglichen sie der Projektleitung die Überprüfung
des aktuellen Status der Entwicklung und sichern die Vollständigkeit des Systemmodells
ab."

text: "The requirements for the development of mechatronic systems have steadily
increased since the first version of VDI Guideline 2206 in 2004. After a comprehensive
revision, the guideline has been republished in white print. In addition to systems
thinking as a strengthened core element of the V-Modell and six control points
for structuring the factual-logical tasks, the consistently explicit \"modeling
and analysis\" is an essential innovation of the guideline. Since the control
questions only refer to the development process as a whole, the following research
question is considered by looking at the modeling of a battery system from a development
project of a German automobile manufacturer: Which specific control questions
regarding the progress of the modeling of a battery management system can be derived
from the control points of the V-model (VDI 2206:2020)?\r\nThe results of the
research are detailed control questions with regard to the modeling of a specific
system, which provide methodological support for the Model-Based Systems Engineering
of complex mechatronic systems. In addition, they enable the project management
to check the current status of the development and ensure the completeness of
the system model."

text: At least 5% of questions submitted to search engines ask about cause-effect
relationships in some way. To support the development of tailored approaches that
can answer such questions, we construct Webis-CausalQA-22, a benchmark corpus
of 1.1 million causal questions with answers. We distinguish different types of
causal questions using a novel typology derived from a data-driven, manual analysis
of questions from ten large question answering (QA) datasets. Using high-precision
lexical rules, we extract causal questions of each type from these datasets to
create our corpus. As an initial baseline, the state-of-the-art QA model UnifiedQA
achieves a ROUGE-L F1 score of 0.48 on our new benchmark.
