text: Diese Arbeit behandelt die Modellierung und Optimierung von mit Phasenwechselmaterialien
(PCM) ausgestatteten, energietechnischen Komponenten anhand zweier Fallstudien.
PCM sind Materialien, deren Phasenwechseleigenschaften während des Schmelzens
und Erstarrens für Heiz- und Kühlzwecke genutzt werden. Zunächst werden die theoretischen
Grundlagen zu Wärmeübertragungsproblemen mit Phasenwechsel erörtert und entsprechende
numerische Lösungsmethoden diskutiert. Ein Modell für Phasenwechselvorgänge wird
vorgestellt, welches anhand analytischer Lösungen validiert wurde und in den Fallstudien
zum Einsatz kam. Für beide Fallstudien wird der Stand der Technik erörtert und
die entsprechenden Forschungsfragen werden formuliert. Die erste Fallstudie behandelt
PCM-integrierte Photovoltaikmodule und die zweite Festbett-Latentwärmespeicher,
welche nicht-kugelförmiger PCM-Kapseln verwenden. Für beide Systeme wurden thermische
Model-le entwickelt und anhand experimenteller Daten mit guter Genauigkeit validiert.
Diese Modelle wurden in Parameterstudien eingesetzt, um optimierte Systemkonfigurationen
zu identifizieren. Die vorgestellten Ergebnisse zeigen, dass ein PCM-Kühlkörper
mit ausreichender Dicke und Wärmeleitfähigkeit den Wirkungsgrad und die Lebensdauer
von Photovoltaikmodulen erheblich erhöht. Darüber hinaus verbessern PCM-Kapseln
mit hoher Packungs-dichte und Oberfläche sowohl die volumenspezifische Speicherkapazität
als auch die thermische Leistung von Festbett-Latentwärmespeichern.

text: This thesis explores the modeling and optimization of energy system components
incorporating phase change materials (PCM) through two different case studies.
PCM are materials whose phase change characteristics during melting and solidification
are utilized for heating and cooling purposes. The theoretical foundations of
heat transfer problems involving phase change, along with the relevant numerical
solution methods, are discussed. A phase change model is presented, which was
validated against analytical solutions and applied in the case studies. For both
case studies, a review of the state of the art is provided, followed by the formulation
of specific research problems. The first case study investigated PCM-enhanced
photovoltaic modules, while the second focused on packed bed latent heat storages
(PBLHS) utilizing non-spherical PCM capsules. Thermal models were developed for
both systems and validated with good accuracy against experimental data. These
models were employed in parameter studies to identify optimized system configurations.
The presented results demonstrate that a PCM heat sink with sufficient thickness
and thermal conductivity can significantly improve the efficiency and lifespan
of photovoltaic modules. Furthermore, PCM capsules with both high packing density
and surface area increase the volume-specific storage capacity and thermal power
output of PBLHS.

text: 'To obtain a more comprehensive understanding of the specific properties
of complex-shaped technical aerosols—such as partially sintered aggregates formed
in combustion processes or structured particles resulting from complex synthesis
processes—it is essential to measure more than a single equivalent size. This
study examines a novel method for determining a two-dimensional distribution of
two distinct particle properties within the size range from 50nm to 1000nm: the
Centrifugal Differential Mobility Analyzer (CDMA). The CDMA enables the simultaneous
measurement of both mobility and Stokes equivalent diameters, providing a detailed
two-dimensional particle property distribution. This, in turn, allows for the
extraction of shape-related information, which is essential for characterizing
particles in terms of their chemical composition, reactivity, and other physicochemical
properties. This paper presents a detailed evaluation of a first CDMA prototype.
First, CFD simulations of the flow field within the classifier are presented in
order to assess and understand non-idealities arising from the exact geometry.
Subsequently, the transfer function is evaluated by particle trajectory calculations
based on the simulated flow field. It can be demonstrated that the simulated transfer
functions agree quite well with transfer functions derived from streamlines of
an ideal flow field, indicating that the non-idealities in the classifying region
are almost negligible in their effect on the classification result. An experimental
determination of the transfer function shows additional effects not covered by
the previous simulations, like broadening by diffusion and losses due to diffusion
and precipitation within the in- and outlet of the classifier. Finally, the determined
transfer functions are used to determine the full two-dimensional distribution
with regard to the mobility and Stokes equivalent diameter of real aerosols, like
spherical particles and aggregates at different sintering stages, respectively.'

text: Within the current energy and environmental crisis, new material- and energy-saving
processes are needed. For this reason, this study focuses on the development of
a new forming technology for Ti-6Al-4V sheet metal. It is based on combination
of solution treatment by resistive heating with rapid tool-based quenching and
subsequent annealing. This new “TISTRAQ” process is comparable with press-hardening
already known for steels and hot die quenching known for aluminium alloys. One
of the main influencing factors for this process is the heat transfer coefficient
(HTC). It is an important driver for adjustment of basic parameters, as selection
of tool material or the forming speed but also plays an important role while elaborating
temperature distribution in the numerical model. Therefore, a new and unique test
rig was developed to determine the HTC and to perform tool-based heat treatment
at specimen level under laboratory conditions. The test rig was used to investigate
the influence of the titanium-tool-lubricant system on HTC and cooling rate. Further
the effect of heat treatment in the test rig and tool-based quenching on microstructure
and mechanical properties was studied. To improve the prediction of the temperature
distribution of the titanium during cooling, the HTC was integrated into the numerical
process simulation

text: Validating assertions before adding them to a knowledge graph is an essential
part of its creation and maintenance. Due to the sheer size of knowledge graphs,
automatic fact-checking approaches have been developed. These approaches rely
on reference knowledge to decide whether a given assertion is correct. Recent
hybrid approaches achieve good results by including several knowledge sources.
However, it is often impractical to provide a sheer quantity of textual knowledge
or generate embedding models to leverage these hybrid approaches. We present FaVEL,
an approach that uses algorithm selection and ensemble learning to amalgamate
several existing fact-checking approaches that rely solely on a reference knowledge
graph and, hence, use fewer resources than current hybrid approaches. For our
evaluation, we create updated versions of two existing datasets and a new dataset
dubbed FaVEL-DS. Our evaluation compares our approach to 15 fact-checking approaches—including
the state-of-the-art approach HybridFC—on 3 datasets. Our results demonstrate
that FaVEL outperforms all other approaches significantly by at least 0.04 in
terms of the area under the ROC curve. Our source code, datasets, and evaluation
results are open-source and can be found at https://github.com/dice-group/favel.

text: Clinical depression is a serious mental disorder that poses challenges for
both personal and public health. Millions of people struggle with depression each
year, but for many, the disorder goes undiagnosed or untreated. Over the last
decade, early depression detection on social media emerged as an interdisciplinary
research field. However, there is still a gap in detecting hesitant, depression-susceptible
individuals with minimal direct depressive signals at an early stage. We, therefore,
take up this open point and leverage posts from Reddit to fill the addressed gap.
Our results demonstrate the potential of contemporary Transformer architectures
in yielding promising predictive capabilities for mental health research. Furthermore,
we investigate the model’s interpretability using a surrogate and a topic modeling
approach. Based on our findings, we consider this work as a further step towards
developing a better understanding of mental eHealth and hope that our results
can support the development of future technologies.

text: Verifying assertions is an essential part of creating and maintaining knowledge
graphs. Most often, this task cannot be carried out manually due to the sheer
size of modern knowledge graphs. Hence, automatic fact-checking approaches have
been proposed over the last decade. These approaches aim to compute automatically
whether a given assertion is correct or incorrect. However, most fact-checking
approaches are binary classifiers that fail to consider the volatility of some
assertions, i.e., the fact that such assertions are only valid at certain times
or for specific time intervals. Moreover, the few approaches able to predict when
an assertion was valid (i.e., time-point prediction approaches) rely on manual
feature engineering. This paper presents TEMPORALFC, a temporal fact-checking
approach that uses multiple sources of background knowledge to assess the veracity
and temporal validity of a given assertion. We evaluate TEMPORALFC on two datasets
and compare it to the state of the art in fact-checking and time-point prediction.
Our results suggest that TEMPORALFC outperforms the state of the art on the fact-checking
task by 0.13 to 0.15 in terms of Area Under the Receiver Operating Characteristic
curve and on the time-point prediction task by 0.25 to 0.27 in terms of Mean Reciprocal
Rank. Our code is open-source and can be found at https://github.com/dice-group/TemporalFC.

text: The importance of fiber-reinforced plastics for lightweight construction applications
is steadily increasing due to their outstanding weight-specific property values.
However, a decisive disadvantage of these composite materials has so far been
the high material and process costs, which is why fiber-reinforced plastics are
almost exclusively used in small to medium-sized series. Optimization of manufacturing
methods is of great importance to reduce the production cost. In this study, two
concepts are proposed that can optimize vacuum assisted light resin transfer molding
(VA-LRTM) further, leading to a possibility of fully automatic process. Conventional
VA-LRTM methods are used to produce complex fiber-reinforced plastics (FRP) and
hybrid components. Traditional molds used to produce components via VA-LRTM are
sealed using polymer materials to prevent the leakage of matrix system. The seals
undergo tremendous amounts of thermal, chemical, and mechanical loadings. Thus,
sealings must be replaced in short intervals. In the current study, a concept
where sealing is achieved by accelerating the curing of matrix system itself with
the help of heating elements and catalysts resulting in a self-sealing approach
is proposed. Another concern is mold surface contamination during component production.
To address this, a modified automatic cleaning technique based on ultrasonic cleaning
was proposed which can be integrated into the production line with minimum modification.
Both the proposed concepts were validated and optimized using experiments, simulations,
and analytical approaches by producing metal-FRP hybrid shafts.

text: Partial coverage of the traditional grid is one of the factors that con-tribute
to the low electrical energy access levels in developing countries. This often
results in long distances between the grid and unconnected communities. Microgrids,
due to their distributed energy resources, have the potential to increase energy
access levels. However, there is limited access to microgrids-related knowledge.
The knowledge is essential for the effective and efficient use of energy, operation,
and hence sustainability of microgrids. To contribute to the sustainability of
microgrids, a Virtual and Interactive Microgrids Learning Environment (VIMLE)
for microgrids knowledge transfer is developed. VIMLE development is guided by
design-based research. With knowledge transfer and skills acquisition through
the use of VIMLE, local capacity for designing, installing, operating and maintenance
of microgrids is built. Skilled local capacity will contribute to microgrids sustainability.
Hence, improve electrical energy access levels and contribute to the achievement
of SDG 7.

text: The production of hydrogen and the utilization of biomass for sustainable
concepts of energy conversion and storage require gas sensors that discriminate
between hydrogen (H2) and carbon monoxide (CO). Mesoporous copper–ceria (Cu–CeO2)
materials with large specific surface areas and uniform porosity are prepared
by nanocasting, and their textural properties are characterized by N2 physisorption,
powder XRD, scanning electron microscopy, transmission electron microscopy, and
energy-dispersive X-ray spectroscopy. The oxidation states of copper (Cu+, Cu2+)
and cerium (Ce3+, Ce4+) are investigated by XPS. The materials are used as resistive
gas sensors for H2 and CO. The sensors show a stronger response to CO than to
H2 and low cross-sensitivity to humidity. Copper turns out to be a necessary component;
copper-free ceria materials prepared by the same method show only poor sensing
performance. By measuring both gases (CO and H2) simultaneously, it is shown that
this behavior can be utilized for selective sensing of CO in the presence of H2.

text: "Consider the practical goal of making a desired action profile played,\r\n\r\nwhen
the planner can only change the payoffs, bound by \r\n\r\nstringent constraints.\r\n\r\nApplications
include motivating people\r\n\r\nto choose the closest school, the closest subway
station, or to coordinate\r\n\r\non a communication protocol or an investment
strategy.\r\n\r\nEmploying subsidies and tolls, we adjust the game so that choosing
this predefined action profile\r\n\r\nbecomes strictly dominant. \r\n\r\nInspired
mainly by the work of Monderer and Tennenholtz,\r\n\r\nwhere the promised subsidies
do not materialise in the not played\r\n\r\nprofiles, we provide a fair and individually
rational game\r\n\r\nadjustment, such that the total outside investments sum up\r\n\r\nto
zero at any profile, thereby facilitating easy and frequent\r\n\r\nusage of our
adjustment without bearing costs, even if some\r\n\r\nplayers behave unexpectedly.
The resultant action profile itself needs no\r\n\r\nadjustment. Importantly, we
also prove that our adjustment minimises \r\n\r\nthe general transfer among all
such adjustments, counting the total subsidising and taxation."

text: In this study, quasi-unidirectional continuous fiber reinforced thermoplastics
(CFRTs) are joined with metal sheets via cold formed cylindrical, elliptical and
polygonal pin structures which are directly pressed into the CFRT component after
local infrared heating. In comparison to already available studies, the unique
novelty is the use of non-rotational symmetric pin structures for the CFRT/metal
hybrid joining. Thus, a variation in the fiber orientation in the CFRT component
as well as a variation in the non-rotational symmetric pins’ orientation in relation
to the sample orientation is conducted. The created samples are consequently mechanically
tested via single lap shear experiments in a quasi-static state. Finally, the
failure behavior of the single lap shear samples is investigated with the help
of microscopic images and detailed photographs. In the single lap shear tests,
it could be shown that non-rotational symmetric pin structures lead to an increase
in maximum testing forces of up to 74% when compared to cylindrical pins. However,
when normalized to the pin foot print related joint strength, only one polygonal
pin variation showed increased joint strength in comparison to cylindrical pin
structures. The investigation of the failure behavior showed two distinct failure
modes. The first failure mode was failure of the CFRT component due to an exceedance
of the maximum bearing strength of the pin-hole leading to significant damage
in the CFRT component. The second failure mode was pin-deflection due to the applied
testing load and a subsequent pin extraction from the CFRT component resulting
in significantly less visible damage in the CFRT component. Generally, CFRT failure
is more likely with a fiber orientation of 0° in relation to the load direction
while pin extraction typically occurs with a fiber orientation of 90°. It is assumed
that for future investigations, pin structures with an undercutting shape that
creates an interlocking joint could counteract the tendency for pin-extraction
and consequently lead to increased maximum joint strengths.

text: Crack growth in structures depends on the cyclic loads applied on it, such
as mechanical, thermal and contact, as well as residual stresses, etc. To provide
an accurate simulation of crack growth in structures, it is of high importance
to integrate all kinds of loading situations in the simulations. Adapcrack3D is
a simulation program that can accurately predict the propagation of cracks in
real structures. However, until now, this three-dimensional program has only considered
mechanical loads and static thermal loads. Therefore, the features of Adapcrack3D
have been extended by including contact loading in crack growth simulations. The
numerical simulation of crack propagation with Adapcrack3D is generally carried
out using FE models of structures provided by the user. For simulating models
with contact loading situations, Adapcrack3D has been updated to work with FE
models containing multiple parts and necessary features such as coupling and surface
interactions. Because Adapcrack3D uses the submodel technique for fracture mechanical
evaluations, the architecture of the submodel is also modified to simulate models
with contact definitions between the crack surfaces. This paper discusses the
newly implemented attribute of the program with the help of illustrative examples.
The results confirm that the contact simulation in Adapcrack3D is a major step
in improving the functionality of the program.

text: Requirement changes and cascading effects of change propagation are
major sources of inefficiencies in product development and increase the risk of
project failure. Proactive change management of requirement changes yields the
potential to handle such changes efficiently. A systematic approach is required
for proactive change management to assess and reduce the risk of a requirement
change with appropriate effort in industrial application. Within the paper at
hand, a novel method for Proactive Management of Requirement Changes (ProMaRC)
is presented. It is developed in close collaboration with industry experts and
evaluated based on workshops, pilot users’ feedback, three industrial case studies
from the automotive industry and five development projects from research. To limit
the application effort, an automated approach for dependency analysis based on
the machine learning technique BERT and semi-automated assessment of change likelihood
and impact using a modified PageRank algorithm is developed. Applying the method,
the risks of requirement changes are assessed systematically and reduced by means
of proactive change measures. Evaluation shows high performance of dependency
analysis and confirms the applicability and usefulness of the method. This contribution
opens up the research space of proactive risk management for requirement changes
which is currently almost unexploited. It enables more efficient product development.

text: 'Content is the new oil. Users consume billions of terabytes a day while surfing
on news sites or blogs, posting on social media sites, and sending chat messages
around the globe. While content is heterogeneous, the dominant form of web content
is text. There are situations where more diversity needs to be introduced into
text content, for example, to reuse it on websites or to allow a chatbot to base
its models on the information conveyed rather than of the language used. In order
to achieve this, paraphrasing techniques have been developed: One example is Text
spinning, a technique that automatically paraphrases text while leaving the intent
intact. This makes it easier to reuse content, or to change the language generated
by the bot more human. One method for modifying texts is a combination of translation
and back-translation. This paper presents NATTS, a naive approach that uses transformer-based
translation models to create diversified text, combining translation steps in
one model. An advantage of this approach is that it can be fine-tuned and handle
technical language.'

text: "Employing a unique hand-collected sample of 956 credit risk securitization
transactions issued by 64 stock-listed\r\nEuropean banks across the EU-13 plus
Switzerland over the period from 1997 to 2010, this paper empirically analyzes\r\nthe
impact of securitization on the issuing banks’ effective tax rates. Our analysis
reveals that banks may reduce their\r\ntax expense through securitization via
a direct and indirect channel suggesting that tax avoidance may be a further\r\nmotive
for banks to engage in the securitization business. These baseline findings remain
robust under various\r\nrobustness checks, especially when implementing structural
equation models and controlling for a reverse causality\r\nbetween the banks’
tax burden and their incentive to securitize. Finally, various sensitivity analyses
provide further\r\nimportant results and implications for tax policies, banking
regulation and the ongoing process of revitalizing the\r\nEuropean securitization
market."
