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: The introduction of Systems Engineering is an approach for dealing
with the increasing complexity of products and their associated product development.
Several introduction strategies are available in the literature; nevertheless,
the introduction of Systems Engineering into practice still poses a great challenge
to companies. Many companies have already gained experience in the introduction
of Systems Engineering. Therefore, as part of the SE4OWL research project, the
need to conduct a study including expert interviews and to collect the experiences
of experts was identified. A total of 78 hypotheses were identified from 13 expert
interviews concerning the lessons learned. Using exclusion criteria, 52 hypotheses
were validated in a subsequent quantitative survey with 112 participants. Of these
52 hypotheses, 40 could be confirmed based on the survey results. Only four hypotheses
were rejected, and eight could neither be confirmed nor rejected. Through this
research, guidance is provided to companies to leverage best practices for the
introduction of their own Systems Engineering and to avoid the poor practices
of other companies.

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: "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: "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."
