text: The current investigation shows the feasibility of 316L steel powder
production via three different argon gas atomisation routes (closed coupled atomisation,
free fall atomisation with and without hot gas), along with subsequent sample
production by laser powder bed fusion (PBF-LB). Here, a mixture of pure Fe and
atomised 316L steel powder is used for PBF-LB to induce a chemical composition
gradient in the microstructure. Optical microscopy and μ-CT investigations proved
that the samples processed by PBF-LB exhibit very little porosity. Combined EBSD-EDS
measurements show the chemical composition gradient leading to the formation of
a local fcc-structure. Upon heat treatment (1100 °C, 14 h), the chemical composition
is homogeneous throughout the microstructure. A moderate decrease (1060 to 985
MPa) in the sample’s ultimate tensile strength (UTS) is observed after heat treatment.
However, the total elongation of the as-built and heat-treated samples remains
the same (≈22%). Similarly, a slight decrease in the hardness from 341 to 307
HV1 is observed upon heat treatment.

text: "This paper reveals the 3D character of the intermetallic layer at the aluminum–steel
interface which pops\r\nup above the original sample surface during annealing.
Popping out of the intermetallics was proven using\r\natomic force microscopy.
The phase expands out of the plane due to the exothermic formation of the Al5Fe2\r\nphase
and the feasibility of surface diffusion. Milling by a focused ion beam enabled
the comparison of the\r\nchemical composition of the surface layer with the bulk
interface, showing no difference. The growth direction\r\nis both towards aluminum
and steel — the main diffusion flux is from aluminum towards steel, and the new\r\nintermetallic
phase emerges at the steel side. The shortage of Al atoms causes a shift of the
intermetallic as a\r\nwhole towards aluminum."

text: "AbstractThree prominent low order implicit
time integration schemes are the first order implicit Euler-method, the second
order trapezoidal rule and the second order Ellsiepen method. Its advantages are
stability and comparatively low computational cost, however, they require the
solution of a nonlinear system of equations. This paper presents a general approach
for the construction of third order Runge–Kutta methods by embedding the above
mentioned implicit schemes into the class of ELDIRK-methods. These will be defined
to have an Explicit Last stage in the general Butcher
array of Diagonal Implicit Runge–Kutta (DIRK) methods,
with the consequence, that no additional system of equations must be solved. The
main results—valid also for non-linear ordinary differential equations—are as
follows: Two extra function calculations are required in order to embed the implicit
Euler-method and one extra function calculation is required for the trapezoidal-rule
and the Ellsiepen method, in order to obtain the third order properties, respectively.
Two numerical examples are concerned with a parachute with viscous damping and
a two-dimensional laser beam simulation. Here, we verify the higher order convergence
behaviours of the proposed new ELDIRK-methods, and its successful performances
for asymptotically exact global error estimation of so-called reversed embedded
RK-method are shown.\r\n"

text: The development of automotive components with reduced greenhouse gas
(GHG) emissions is needed to reduce overall vehicle emissions. Life Cycle Engineering
(LCE) based on Life Cycle Assessment (LCA) supports this by providing holistic
information and improvement potentials regarding eco-efficient products. Key factors
influencing LCAs of automotive components, such as material production, will change
in the future. First approaches for integrating future scenarios for these key
factors into LCE already exist, but they only consider a limited number of parameters
and scenarios. This work aims to develop a method that can be practically applied
in the industry for integrating prospective LCAs (pLCA) into the LCE of automotive
components, considering relevant parameters and consistent scenarios. Therefore,
pLCA methods are further developed to investigate the influence of future scenarios
on the GHG emissions of automotive components. The practical application is demonstrated
for a vehicle component with different design options. This paper shows that different
development paths of the foreground and background system can shift the ecological
optimum of design alternatives. Therefore, future pathways of relevant parameters
must be considered comprehensively to reduce GHG emissions of future vehicles.
This work contributes to the methodological and practical integration of pLCA
into automotive development processes and provides quantitative results.

text: 'Many applications require explainable node classification in knowledge graphs.
Towards this end, a popular ``white-box'''' approach is class expression learning:
Given sets of positive and negative nodes, class expressions in description logics
are learned that separate positive from negative nodes. Most existing approaches
are search-based approaches generating many candidate class expressions and selecting
the best one. However, they often take a long time to find suitable class expressions.
In this paper, we cast class expression learning as a translation problem and
propose a new family of class expression learning approaches which we dub neural
class expression synthesizers. Training examples are ``translated'''' into class
expressions in a fashion akin to machine translation. Consequently, our synthesizers
are not subject to the runtime limitations of search-based approaches. We study
three instances of this novel family of approaches based on LSTMs, GRUs, and set
transformers, respectively. An evaluation of our approach on four benchmark datasets
suggests that it can effectively synthesize high-quality class expressions with
respect to the input examples in approximately one second on average. Moreover,
a comparison to state-of-the-art approaches suggests that we achieve better F-measures
on large datasets. For reproducibility purposes, we provide our implementation
as well as pretrained models in our public GitHub repository at https://github.com/dice-group/NeuralClassExpressionSynthesis'

text: "Reading between the lines has so far been reserved for humans. The present
dissertation addresses this research gap using machine learning methods.\r\nImplicit
expressions are not comprehensible by computers and cannot be localized in the
text. However, many texts arise on interpersonal topics that, unlike commercial
evaluation texts, often imply information only by means of longer phrases. Examples
are the kindness and the attentiveness of a doctor, which are only paraphrased
(“he didn’t even look me in the eye”). The analysis of such data, especially the
identification and localization of implicit statements, is a research gap (1).
This work uses so-called Aspect-based Sentiment Analysis as a method for this
purpose. It remains open how the aspect categories to be extracted can be discovered
and thematically delineated based on the data (2). Furthermore, it is not yet
explored how a collection of tools should look like, with which implicit phrases
can be identified and thus made explicit\r\n(3). Last, it is an open question
how to correlate the identified phrases from the text data with other data, including
the investigation of the relationship between quantitative scores (e.g., school
grades) and the thematically related text (4). Based on these research gaps, the
research question is posed as follows: Using text mining methods, how can implicit
rating content be properly interpreted and thus made explicit before it is automatically
categorized and quantified?\r\nThe uniqueness of this dissertation is based on
the automated recognition of implicit linguistic statements alongside explicit
statements. These are identified in unstructured text data so that features expressed
only in the text can later be compared across data sources, even though they were
not included in rating categories such as stars or school grades. German-language
physician ratings from websites in three countries serve as the sample domain.
The solution approach consists of data creation, a pipeline for text processing
and analyses based on this. In the data creation, aspect classes are identified
and delineated across platforms and marked in text data. This results in six datasets
with over 70,000 annotated sentences and detailed guidelines. The models that
were created based on the training data extract and categorize the aspects. In
addition, the sentiment polarity and the evaluation weight, i. e., the importance
of each phrase, are determined. The models, which are combined in a pipeline,
are used in a prototype in the form of a web application. The analyses built on
the pipeline quantify the rating contents by linking the obtained information
with further data, thus allowing new insights.\r\nAs a result, a toolbox is provided
to identify quantifiable rating content and categories using text mining for a
sample domain. This is used to evaluate the approach, which in principle can also
be adapted to any other domain."

text: This work reports a fully guided setup for single-mode squeezing on
integrated titanium-indiffused periodically poled nonlinear resonators. A continuous-wave
laser beam is delivered and the squeezed field is collected by single-mode fibers;
up to −3.17(9) dB of useful squeezing is available in fibers. To showcase the
usefulness of such a fiber-coupled device, we applied the generated squeezed light
in a fiber-based phase sensing experiment, showing a quantum enhancement in the
signal-to-noise ratio of 0.35 dB. Moreover, our investigation of the effect of
photorefraction on the cavity resonance condition suggests that it causes system
instabilities at high powers.

text: We present a concept for quantifying evaluative phrases to later compare rating
texts numerically instead of just relying on stars or grades. We achievethis by
combining deep learning models in an aspect-based sentiment analysis pipeline
along with sentiment weighting, polarity, and correlation analyses that combine
deep learning results with metadata. The results provide new insights for the
medical field. Our application domain, physician reviews, shows that there are
millions of review texts on the Internet that cannot yet be comprehensively analyzed
because previous studies have focused on explicit aspects from other domains (e.g.,
products). We identify, extract, and classify implicit and explicit aspect phrases
equally from German-language review texts. To do so, we annotated aspect phrases
representing reviews on numerous aspects of a physician, medical practice, or
practice staff. We apply the best performing transformer model, XLM-RoBERTa, to
a large physician review dataset and correlate the results with existing metadata.
As a result, we can show different correlations between the sentiment polarity
of certain aspect classes (e.g., friendliness, practice equipment) and physicians’
professions (e.g., surgeon, ophthalmologist). As a result, we have individual
numerical scores that contain a variety of information based on deep learning
algorithms that extract textual (evaluative) information and metadata from the
Web.

text: "The computation of electron repulsion integrals (ERIs) over Gaussian-type
orbitals (GTOs) is a challenging problem in quantum-mechanics-based atomistic
simulations. In practical simulations, several trillions of ERIs may have to be\r\ncomputed
for every time step.\r\nIn this work, we investigate FPGAs as accelerators for
the ERI computation. We use template parameters, here within the Intel oneAPI
tool flow, to create customized designs for 256 different ERI quartet classes,
based on their orbitals. To maximize data reuse, all intermediates are buffered
in FPGA on-chip memory with customized layout. The pre-calculation of intermediates
also helps to overcome data dependencies caused by multi-dimensional recurrence\r\nrelations.
The involved loop structures are partially or even fully unrolled for high throughput
of FPGA kernels. Furthermore, a lossy compression algorithm utilizing arbitrary
bitwidth integers is integrated in the FPGA kernels. To our\r\nbest knowledge,
this is the first work on ERI computation on FPGAs that supports more than just
the single most basic quartet class. Also, the integration of ERI computation
and compression it a novelty that is not even covered by CPU or GPU libraries
so far.\r\nOur evaluation shows that using 16-bit integer for the ERI compression,
the fastest FPGA kernels exceed the performance of 10 GERIS ($10 \\times 10^9$
ERIs per second) on one Intel Stratix 10 GX 2800 FPGA, with maximum absolute errors
around $10^{-7}$ - $10^{-5}$ Hartree. The measured throughput can be accurately
explained by a performance model. The FPGA kernels deployed on 2 FPGAs outperform
similar computations using the widely used libint reference on a two-socket server
with 40 Xeon Gold 6148 CPU cores of the same process technology by factors up
to 6.0x and on a new two-socket server with 128 EPYC 7713 CPU cores by up to 1.9x."

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"
