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.

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"

text: 'In order to reduce the fuel consumption and consequently the greenhouse emissions,
the automotive industry is implementing lightweight constructions in the body
in white production. As a result, the use of aluminum alloys is continuously increasing.
Due to poor weldability of aluminum in combination with other materials, mechanical
joining technologies like clinching are increasingly used. In order to predict
relevant characteristics of clinched joints and to ensure the reliability of the
process, it is simulated numerically during product development processes. In
this regard the predictive accuracy of the simulated process highly depends on
the implemented friction model. In particular, the frictional behavior between
the sheet metals affects the geometrical formation of the clinched joint significantly.
This paper presents a testing method, which enables to determine the frictional
coefficients between sheet metal materials for the simulation of clinching processes.
For this purpose, the correlation of interface pressure and the relative velocity
between aluminum sheets in clinching processes is investigated using numerical
simulation. Furthermore, the developed testing method focuses on the specimen
geometry as well as the reproduction of the occurring friction conditions between
two sheet metal materials in clinching processes. Based on a methodical approach
the test setup is explained and the functionality of the method is proven by experimental
tests using sheet metal material EN AW6014. '

text: Ultrasonic wire bonding is a solid-state joining process, used in the electronics
industry to form electrical connections, e.g. to connect electrical terminals
within semiconductor modules. Many process parameters affect the bond strength,
such like the bond normal force, ultrasonic power, wire material and bonding frequency.
Today, process design, development, and optimization is most likely based on the
knowledge of process engineers and is mainly performed by experimental testing.
In this contribution, a newly developed simulation tool is presented, to reduce
time and costs and efficiently determine optimized process parameter. Based on
a co-simulation of MATLAB and ANSYS, the different physical phenomena of the wire
bonding process are considered using finite element simulation for the complex
plastic deformation of the wire and reduced order models for the transient dynamics
of the transducer, wire, substrate and bond formation. The model parameters such
as the coefficients of friction between bond tool and wire and between wire and
substrate were determined for aluminium and copper wire in experiments with a
test rig specially developed for the requirements of heavy wire bonding. To reduce
simulation time, for the finite element simulation a restart analysis and high
performance computing is utilized. Detailed analysis of the bond formation showed,
that the normal pressure distribution in the contact between wire and substrate
has high impact on bond formation and distribution of welded areas in the contact
area.

text: As an effective and accurate method for modelling composite materials, mean-field
homogenization is still not well studied in modelling non-linear and damage behaviours
of UD composites. Investigated micro FE-simulations show that the matrix of UD
composites exhibits different average plastic behaviour, named as average asymmetric
matrix plasticity (AAMP), when the composite behaves different under shear, longitudinal
and transverse loadings. In this study, a non-linear mean-field debonding model
(NMFDM) combining a mean-field model and a fibre–matrix interface debonding model,
is developed to simulate UD composites under consideration of AAMP, fibre–matrix
interface damage and progressive failure. AAMP is considered by using so-called
stress mode factor, which is expressed in terms of basic invariants of the matrix
deviatoric stress tensor and is used as an indicator for detection of differences
in the loading mode. The material behaviour of UD composites with imperfect interface
is assumed identical as for perfect interface and stiffness reduced fibres. Progressive
failure criteria are established with consideration of fibre breakage and matrix
crack for different fibre orientations. As a representative example for the NMFDM,
a C30/E201 UD composite is studied. To verify the model, experiments are conducted
on polymers, carbon fibres and UD CFRPs. Finally, the model is applied to simulate
a perforated CFRP laminate, which shows excellent prediction ability on deformation,
debonding and progressive failure.

text: "The online fitting of a microscopic traffic simulation model to reconstruct
the current state of a real traffic\r\narea can be challenging depending on the
provided data. This paper presents a novel method based on limited\r\ndata from
sensors positioned at specific locations and guarantees a general accordance of
reality and\r\nsimulation in terms of multimodal road traffic counts and vehicle
speeds. In these considerations, the actual\r\npurpose of research is of particular
importance. Here, the research aims at improving the traffic flow by\r\ncontrolling
the Traffic Light Systems (TLS) of the examined area which is why the current
traffic state and\r\nthe route choices of individual road users are the matter
of interest. An integer optimization problem is derived\r\nto fit the current
simulation to the latest field measurements. The concept can be transferred to
any road traffic\r\nnetwork and results in an observation of the current multimodal
traffic state matching at the given sensor\r\nposition. First case studies show
promosing results in terms of deviations between reality and simulation."
