text: Far-field multi-speaker automatic speech recognition (ASR) has drawn increasing
attention in recent years. Most existing methods feature a signal processing frontend
and an ASR backend. In realistic scenarios, these modules are usually trained
separately or progressively, which suffers from either inter-module mismatch or
a complicated training process. In this paper, we propose an end-to-end multi-channel
model that jointly optimizes the speech enhancement (including speech dereverberation,
denoising, and separation) frontend and the ASR backend as a single system. To
the best of our knowledge, this is the first work that proposes to optimize dereverberation,
beamforming, and multi-speaker ASR in a fully end-to-end manner. The frontend
module consists of a weighted prediction error (WPE) based submodule for dereverberation
and a neural beamformer for denoising and speech separation. For the backend,
we adopt a widely used end-to-end (E2E) ASR architecture. It is worth noting that
the entire model is differentiable and can be optimized in a fully end-to-end
manner using only the ASR criterion, without the need of parallel signal-level
labels. We evaluate the proposed model on several multi-speaker benchmark datasets,
and experimental results show that the fully E2E ASR model can achieve competitive
performance on both noisy and reverberant conditions, with over 30% relative word
error rate (WER) reduction over the single-channel baseline systems.

text: AbstractComprehensive data understanding
is a key success driver for data analytics projects. Knowing the characteristics
of the data helps a lot in selecting the appropriate data analysis techniques.
Especially in data-driven product planning, knowledge about the data is a necessary
prerequisite because data of the use phase is very heterogeneous. However, companies
often do not have the necessary know-how or time to build up solid data understanding
in connection with data analysis. In this paper, we develop a methodology to organize
and categorize and thus understand use phase data in a way that makes it accessible
to general data analytics workflows, following a design science research approach.
We first present a knowledge base that lists typical use phase data from a product
planning view. Second, we develop a taxonomy based on standard literature and
real data objects, which covers the diversity of the data considered. The taxonomy
provides 8 dimensions that support classification of use phase data and allows
to capture data characteristics from a data analytics view. Finally, we combine
both views by clustering the objects of the knowledge base according to the taxonomy.
Each of the resulting clusters covers a typical combination of analytics relevant
characteristics occurring in practice. By abstracting from the diversity of use
phase data into artifacts with manageable complexity, our approach provides guidance
to choose appropriate data analysis and AI techniques.

text: Mounting sensors in disk stack separators is often a major challenge
due to the operating conditions. However, a process cannot be optimally monitored
without sensors. Virtual sensors can be a solution to calculate the sought parameters
from measurable values. We measured the vibrations of disk stack separators and
applied machine learning (ML) to detect whether the separator contains only water
or whether particles are also present. We combined seven ML classification algorithms
with three feature engineering strategies and evaluated our model successfully
on vibration data of an experimental disk stack separator. Our experimental results
demonstrate that random forest in combination with manual feature engineering
using domain specific knowledge about suitable features outperforms all other
models with an accuracy of 91.27 %.

text: Praxeologische Kompetenzansätze verstehen Kompetenz als sozial erlernt
und folglich als relativ zum sozialen Kontext. Damit einher geht die Frage, wie
solche praxeologisch gerahmten Kompetenzen eigentlich unabhängig von der sie hervorbringenden
Praxis evaluiert werden können – und eben dadurch erst für einen breiteren Kompetenzdiskurs
fruchtbar sind. Die Dokumentarische Evaluationsforschung bietet hierzu erste Anhaltspunkte,
offenbart aber auch Grenzen, die mit dem Evaluationsverständnis zusammenhängen,
sich jedoch in der Forschungspraxis so nicht finden lassen. Aus der Differenz
zwischen Methode und Praxis dokumentarischer Evaluation lässt sich formulieren,
wie eine praxeologische Evaluation gestaltet werden könnte. Dabei spielt die Formulierung
von Referenzrahmen eine zentrale Rolle, welche einerseits der zu evaluierenden
Praktik external sein, andererseits praktisch formuliert werden müssen, damit
sie soziale Praktiken jenseits ihrer eigenen Sinnhaftigkeit evaluativ (er-)fassen
können.

text: AlSi casting alloys combine excellent castability with high strength. Hence,
this group of alloys is often used in the automotive sector. The challenge for
this application is the brittle character of these alloys which leads to cracks
during joint formation when mechanical joining technologies are used. A rise in
ductility can be achieved by a considerable increase in the solidification rate
which results in grain refinement. High solidification rates can be realized in
twin–roll casting (TRC) by water-cooled rolls. Therefore, a hypoeutectic EN AC–AlSi9
(for European Norm - aluminum cast product) is manufactured by the TRC process
and analyzed. Subsequently, joining investigations are performed on castings in
as-cast and heat-treated condition using the self-piercing riveting process considering
the joint formation and the load-bearing capacity. Due to the fine microstructure,
the crack initiation can be avoided during joining, while maintaining the joining
parameters, especially by specimens in heat treatment conditions. Furthermore,
due to the extremely fine microstructure, the load-bearing capacity of the joint
can be significantly increased in terms of the maximum load-bearing force and
the energy absorbed.

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: In this paper, a study based on experimental and numerical simulations is
performed to analyze fatigue cracks in clinched joints. An experimental investigation
is conducted to determine the failure modes of clinched joints under cyclic loading
at different load amplitudes with single-lap shear tests. In addition, numerical
FEM simulations of clinching process and subsequent shear loading are performed
to support the experimental investigations by analyzing the state of stresses
at the location of failure. An attempt is made to explain the location of crack
initiation in the experiments using evaluation variables such as contact shear
stress and maximum principal stress.

text: "Force–displacement measurements and micrograph analyses are commonly used
methods to validate numerical models of clinching processes. However, these methods
often lead to resetting of elastic deformations and crack-\r\nclosing after unloading.
In contrast, the in situ computed tomography (CT) can provide three-dimensional
images of the clinch point under loading conditions. In this paper, the potential
of the in situ investigation of a clinching process as validation method is analyzed.
For the in situ testing, a tailored test set-up featuring a beryllium cylinder
for load-bearing and clinching tools made from ultra-high-strength titanium and
Si3N4 are used. In the experiments, the clinching of two aluminum sheets is interrupted
at specific process steps in order to perform the CT scans. It is shown that in
situ CT visualizes the inner geometry of the joint at high precision and that
this method is suitable to validate numerical models."

text: Resource-saving and sustainable production is becoming increasingly important
regarding social, political and economic aspects, thus making the use of lightweight-construction
technologies a current trend. For this reason, multi-material-systems made of
high-strength steel and aluminium as well as metal and fibre-reinforced plastics
gain in importance. However, different material properties, e.g. stiffness, thermal
expansion coefficients or chemical incompatibilities, are challenging for conventional
joining technologies. Joining by cold formed pin structures has shown to have
high potential for joining multi-material-systems. These pins can be joined either
by direct pin pressing into an unperforated joining partner or by caulking, where
the pins are inserted through a pre-punched joining partner and the pin head is
upset, resulting in a form-fit joint. Usually, cylindrical pins are used for joining.
However, non-rotationally symmetrical pin geometries offer the possibility of
introducing a predetermined breaking point or reinforcing a connection in the
principal force direction. In this work, cylindrical pins as well as non-rotationally
symmetrical pin geometries, such as polygonal and oval pin structures, are cold
extruded from the sheet metal plane of an HCT590X+Z dual phase steel and joined
in the next step with an EN AW-6014 aluminium using direct pin pressing. Since
the formation of an undercut has an crucial influence on the joint strength, the
investigations will be focused on the resulting joint geometry. In addition, the
effect of different pin heights will be examined to analyse the joint formation
at different levels of compression of the pin structures. Finally, the joints
are evaluated regarding their joint strength in tensile shear tests and cross
tension tests. Here the flow resistance of the geometry used as well as the pin
height and thus the strain hardening of the pin base during the extrusion of the
pins play a decisive role for the shear strength.
