text: "Iron oxide nanoparticles are very interesting for many applications in different
industrial sectors. A promising\r\nprocess to manufacture these nanoparticles
is flame spray pyrolysis (FSP). A lack of understanding of the\r\nindividual sub-processes
in FSP makes it challenging to tailor nanoparticle properties. This work provides\r\ninsights
into the formation of iron oxide nanoparticles in a turbulent spray flame using
Large Eddy Simulations\r\n(LES), which are based on a comprehensive model, including
customized submodels. Highlights are the\r\nadaption of a turbulent combustion
model and a bivariate hybrid method of moments for modeling nanoparticle\r\ndynamics.
The work focuses on the SpraySyn burner, which is a standardized laboratory burner
and was\r\noperated with a precursor-solvent mixture of ethanol and iron(III)
nitrate nonahydrate. For studying the\r\nrelevance of precursor chemistry, LES
using an evaporation-limited precursor chemistry model is compared\r\nwith a model
that includes detailed iron chemistry. A further novelty is the inclusion of adsorption
in the\r\nsimulation, which defines a third model for comparison. Sufficient validation
is achieved for the undoped LES\r\nusing experimental data from the literature.
A strong impact of the detailed iron chemistry and adsorption\r\nis found on the
precursor consumption and the aggregate and primary particle formation. Comparing
the\r\nparticle diameters with experimental measurements from the literature and
data generated for this work is\r\nfound unsuitable to asses the precursor chemistry
model and revealed an urgent need for future experimental\r\nand numerical research.
This work serves as a step forward in realizing a reliable model."

text: 'In virtual reality (VR), participants may not always have hands,
bodies, eyes, or even voices—using VR helmets and two controllers, participants
control an avatar through virtual worlds that do not necessarily obey familiar
laws of physics; moreover, the avatar’s bodily characteristics may not neatly
match our bodies in the physical world. Despite these limitations and specificities,
humans get things done through collaboration and the creative use of the environment.
While multiuser interactive VR is attracting greater numbers of participants,
there are currently few attempts to analyze the in situ interaction systematically.
This paper proposes a video-analytic detail-oriented methodological framework
for studying virtual reality interaction. Using multimodal conversation analysis,
the paper investigates a nonverbal, embodied, two-person interaction: two players
in a survival game strive to gesturally resolve a misunderstanding regarding an
in-game mechanic—however, both of their microphones are turned off for the duration
of play. The players’ inability to resort to complex language to resolve this
issue results in a dense sequence of back-and-forth activity involving gestures,
object manipulation, gaze, and body work. Most crucially, timing and modified
repetitions of previously produced actions turn out to be the key to overcome
both technical and communicative challenges. The paper analyzes these action sequences,
demonstrates how they generate intended outcomes, and proposes a vocabulary to
speak about these types of interaction more generally. The findings demonstrate
the viability of multimodal analysis of VR interaction, shed light on unique challenges
of analyzing interaction in virtual reality, and generate broader methodological
insights about the study of nonverbal action.'

text: As a simplified version of a three-component taxis cascade model
accounting for different migration strategies of two population groups in search
of food, a two-component nonlocal nutrient taxis system is considered in a two-dimensional
bounded convex domain with smooth boundary. For any given conveniently regular
and biologically meaningful initial data, smallness conditions on the prescribed
resource growth and on the initial nutrient signal concentration are identified
which ensure the global existence of a global classical solution to the corresponding
no-flux initial-boundary value problem. Moreover, under additional assumptions
on the food production source these solutions are shown to be bounded, and to
stabilize toward semi-trivial equilibria in the large time limit, respectively.

text: 'The success of engineering complex technical systems is determined
by meeting customer requirements and institutional regulations. One example relevant
to the automobile industry is the United Nations Economic Commission of Europe
(UN ECE), which specifies the homologation of automobile series and requires proof
of traceability. The required traceability can be achieved by modeling system
artifacts and their relations in a consistent, seamless model—an effect-chain
model. Currently, no in-depth methodology exists to support engineers in developing
certification-compliant effect-chain models. For this purpose, a new methodology
for certification-compliant effect-chain modeling was developed, which includes
extensions of an existing method, suitable models, and tools to support engineers
in the modeling process. For evaluation purposes, applicability is proven based
on the experience of more than 300 workshops at an automotive OEM and an automotive
supplier. The following case example is chosen to demonstrate applicability: the
development of a window lifter that has to meet the demands of UN ECE Regulations
R156 and R21. Results indicate multiple benefits in supporting engineers with
the certification-compliant modeling of effect chains. Three benefits are goal-oriented
modeling to reduce the necessary modeling capacity, increasing model quality by
applying information quality criteria, and the potential to reduce costs through
automatable effect-chain analyses for technical changes. Further, companies in
the automotive and other industries will benefit from increased modeling capabilities
that can be used for architecture modeling and to comply with other regulations
such as ASPICE or ISO 26262.'

text: The development of autonomous vehicles and their introduction in urban traffic
offer many opportunities for traffic improvements. In this paper, an approach
for a future traffic control system for mixed autonomy traffic environments is
presented. Furthermore, a simulation framework based on the city of Paderborn
is introduced to enable the development and examination of such a system. This
encompasses multiple elements including the road network itself, traffic lights,
sensors as well as methods to analyse the topology of the network. Furthermore,
a procedure for traffic demand generation and routing is presented based on statistical
data of the city and traffic data obtained by measurements. The resulting model
can receive and apply the generated control inputs and in turn generates simulated
sensor data for the control system based on the current system state.

text: "Abstract\r\n Sandwich packings
represent new separation column internals, with a potential to intensify mass
transfer. They comprise two conventional structured packings with different specific
geometrical surface areas. In this work, the complex fluid dynamics in sandwich
packings is modeled using a novel approach based on a one-dimensional, steady
momentum balance of the liquid and gas phases. The interactions between the three
present phases (gas, liquid, and solid) are considered by closures incorporated
into the momentum balance. The formulation of these closures is derived from two
fluid-dynamic analogies for the film and froth flow patterns. The adjustable parameters
in the closures are regressed for the film flow using dry pressure drop measurements
and liquid hold-up data in trickle flow conditions. For the froth flow, the tuning
parameters are fitted to overall pressure drop measurements and local liquid hold-up
data acquired from ultra-fast X-ray tomography (UFXCT). The model predicts liquid
hold-up and pressure drop data with an average relative deviation of 16.4 % and
19 %, respectively. Compared to previous fluid dynamic models for sandwich packings,
the number of adjustable parameters could be reduced while maintaining comparable
accuracy."

text: "Recent reinforcement learning approaches for continuous control in wireless
mobile networks have shown impressive\r\nresults. But due to the lack of open
and compatible simulators, authors typically create their own simulation environments
for training and evaluation. This is cumbersome and time-consuming for authors
and limits reproducibility and comparability, ultimately impeding progress in
the field.\r\n\r\nTo this end, we propose mobile-env, a simple and open platform
for training, evaluating, and comparing reinforcement learning and conventional
approaches for continuous control in mobile wireless networks. mobile-env is lightweight
and implements the common OpenAI Gym interface and additional wrappers, which
allows connecting virtually any single-agent or multi-agent reinforcement learning
framework to the environment. While mobile-env provides sensible default values
and can be used out of the box, it also has many configuration options and is
easy to extend. We therefore believe mobile-env to be a valuable platform for
driving meaningful progress in autonomous coordination of\r\nwireless mobile networks."

text: Distributed, software-intensive systems (e.g., in the automotive sector) must
fulfill communication requirements under hard real-time constraints. The requirements
have to be documented and validated carefully using a systematic requirements
engineering (RE) approach, for example, by applying scenario-based requirements
notations. The resources of the execution platforms and their properties (e.g.,
CPU frequency or bus throughput) induce effects on the timing behavior, which
may lead to violations of the real-time requirements. Nowadays, the platform properties
and their induced timing effects are verified against the real-time requirements
by means of timing analysis techniques mostly implemented in commercial-off-the-shelf
tools. However, such timing analyses are conducted in late development phases
since they rely on artifacts produced during these phases (e.g., the platform-specific
code). In order to enable early timing analyses already during RE, we extend a
scenario-based requirements notation with allocation means to platform models
and define operational semantics for the purpose of simulation-based, platform-aware
timing analyses. We illustrate and evaluate the approach with an automotive software-intensive
system.

text: In this work, methods will be evaluated to numerically calculate the passive
electrical parameters of planar coils. These parameters can then be used to optimize
inductive applications such as wireless power transmission. The focus here will
be on inductive localization, which uses high-frequency magnetic fields and the
resulting induced voltage to provide localization through the coupling parameter
mutual inductance. To achieve localization with high accuracy and best possible
operation (resonance, signal strength, etc.), the coil parameters need to be well
known. For this reason, some numerical methods for the calculation of these quantities
are presented and validated. In addition, the physical effects are thereby considered
in more detail, allowing the localization procedure to be better optimized compared
to simulative black-box methods. The goal should be a dedicated simulation platform
for planar coils to be able to develop training data for neural networks and to
test and optimize localization algorithms.

text: Predicting the durability of components subjected to mechanical load under
environmental conditions leading to corrosion is one of the most challenging tasks
in mechanical engineering. The demand for precise predictions increases with the
desire of lightweight design in transportation due to environmental protection.
Corrosion with its manifold of mechanisms often occurs together with the production
of hydrogen by electrochemical reactions. Hydrogen embrittlement is one of the
most feared damage mechanisms for metal constructions often leading to early and
unexpected failure. Until now, predictions are mostly based on costly experiments.
Hence, a rational predictive model based on the fundamentals of electrochemistry
and damage mechanics has to be developed in order to reduce the costs. In this
work, a first model approach based on classical continuum damage mechanics is
presented to couple both, the damage induced by the mechanical stress and the
hydrogen embrittlement. An elaborated two-scale model based on the selfconsistent
theory is applied to describe the mechanical damage due to fatigue. The electrochemical
kinetics are elucidated through the Langmuir adsorption isotherm and the diffusion
equation to consider the impact of hydrogen embrittlement on the fatigue. The
modeling of the mechanism of hydrogen embrittlement defines the progress of damage
accumulation due to the electrochemistry. The durability results like the S-N
diagram show the influence of hydrogen embrittlement by varying, e.g. the fatigue
frequency or the stress ratio.

text: Recently different evolutionary computation approaches have been developed
that generate sets of high quality diverse solutions for a given optimisation
problem. Many studies have considered diversity 1) as a mean to explore niches
in behavioural space (quality diversity) or 2) to increase the structural differences
of solutions (evolutionary diversity optimisation). In this study, we introduce
a co-evolutionary algorithm to simultaneously explore the two spaces for the multi-component
traveling thief problem. The results show the capability of the co-evolutionary
algorithm to achieve significantly higher diversity compared to the baseline evolutionary
diversity algorithms from the literature.

text: ' We introduce a new phase field model for tumor growth where viscoelastic
effects are taken into account. The model is derived from basic thermodynamical
principles and consists of a convected Cahn–Hilliard equation with source terms
for the tumor cells and a convected reaction–diffusion equation with boundary
supply for the nutrient. Chemotactic terms, which are essential for the invasive
behavior of tumors, are taken into account. The model is completed by a viscoelastic
system consisting of the Navier–Stokes equation for the hydrodynamic quantities,
and a general constitutive equation with stress relaxation for the left Cauchy–Green
tensor associated with the elastic part of the total mechanical response of the
viscoelastic material. For a specific choice of the elastic energy density and
with an additional dissipative term accounting for stress diffusion, we prove
existence of global-in-time weak solutions of the viscoelastic model for tumor
growth in two space dimensions [Formula: see text] by the passage to the limit
in a fully-discrete finite element scheme where a CFL condition, i.e. [Formula:
see text], is required. Moreover, in arbitrary dimensions [Formula:
see text], we show stability and existence of solutions for the fully-discrete
finite element scheme, where positive definiteness of the discrete Cauchy–Green
tensor is proved with a regularization technique that was first introduced by
Barrett and Boyaval [Existence and approximation of a (regularized) Oldroyd-B
model, Math. Models Methods Appl. Sci. 21 (2011) 1783–1837]. After that, we improve
the regularity results in arbitrary dimensions [Formula: see text] and in two
dimensions [Formula: see text], where a CFL condition is required. Then, in two
dimensions [Formula: see text], we pass to the limit in the discretization parameters
and show that subsequences of discrete solutions converge to a global-in-time
weak solution. Finally, we present numerical results in two dimensions [Formula:
see text]. '

text: In timing chain drives, the chain is the critical component regarding the
wear. Relative movements take place at the chain joint between pin and bush, which
lead to wear of the chain joint due to friction and so to chain elongation. The
chain joint is generally lubricated with oils, through which elastohydrodynamic
processes can occur in the gap between the pin and the bush of the chain joint.
A simulation model is developed here to examine these elastohydrodynamic processes
considering a mass conserving cavitation model, the Newtonian flow behaviour of
the lubricant and the structuring of the bush surface, whereby the real form of
the bush is considered. MBS simulations are used to obtain realistic loads on
the chain joint.

- lang: ger
text: "Anwendungen von Laser-Sinter Bauteilen als Sichtteile sind aufgrund der vergleichsweise
schlechten Oberflächenqualität sehr begrenzt. In dieser Arbeit werden dreidimensionale
Kennwerte benutzt, um die Oberflächenqualität von Laser-Sinter Bauteiloberflächen
und die Einflüsse aus unterschiedlichen Bereichen der gesamten Prozesskette zu
evaluieren. Beispielsweise wurden objektive Kennwerte, mit deren Hilfe Orangenhaut
zu identifizieren ist, und Prozessparameter, die diese deutlich vermindern, gefunden.
Mittels Durchführung von haptischen Versuchen wurde das subjektive Empfinden ermittelt
und konnten zu objektiven Kennwerten korreliert werden. Eine mikroskopische Betrachtung
des flachen Oberflächenwinkels mit verschieden farbigen Pulvern zeigt neue Erkenntnisse
zum Anschmelzvorgang von Partikeln an die Schmelze. Zur nachträglichen Glättung
von Oberflächen wurden mechanische, chemische und optische Nachbehandlungsmethoden
verwendet und deren Potential aufgezeigt. Eine abschließende neuartige Simulation
der dreidimensionalen Topografie bildet die Grundlage für ein Programm zur automatischen
und funktionsgerechten Orientierung von Bauteilen, welche am Beispiel eines realen
Bauteils erfolgreich validiert wurde. Zusammengenommen zeigen die Ergebnisse,
dass die richtige Wahl von Bauorientierung und Prozessparametern entscheidend
für die Bauteilqualität ist und selbst eine aufwendige Nachbearbeitung eine ungeschickte
Wahl derer nur schwerlich ausgleichen kann.\r\n"
