text: "Micro- and smart grids (MSG) play an important role both for integrating\r\nrenewable
energy sources in conventional electricity grids and for providing\r\npower supply
in remote areas. Modern MSGs are largely driven by power\r\nelectronic converters
due to their high efficiency and flexibility.\r\nNevertheless, controlling MSGs
is a challenging task due to highest\r\nrequirements on energy availability, safety
and voltage quality within a wide\r\nrange of different MSG topologies. This results
in a high demand for\r\ncomprehensive testing of new control concepts during their
development phase\r\nand comparisons with the state of the art in order to ensure
their feasibility.\r\nThis applies in particular to data-driven control approaches
from the field of\r\nreinforcement learning (RL), whose stability and operating
behavior can hardly\r\nbe evaluated a priori. Therefore, the OpenModelica Microgrid
Gym (OMG) package,\r\nan open-source software toolbox for the simulation and control
optimization of\r\nMSGs, is proposed. It is capable of modeling and simulating
arbitrary MSG\r\ntopologies and offers a Python-based interface for plug \\& play
controller\r\ntesting. In particular, the standardized OpenAI Gym interface allows
for easy\r\nRL-based controller integration. Besides the presentation of the OMG
toolbox,\r\napplication examples are highlighted including safe Bayesian optimization
for\r\nlow-level controller tuning."

text: Mobile shopping apps have been using Augmented Reality (AR) in the last years
to place their products in the environment of the customer. While this is possible
with atomic 3D objects, there is is still a lack in the runtime configuration of
3D object compositions based on user needs and environmental constraints. For
this, we previously developed an approach for model-based AR-assisted product
configuration based on the concept of Dynamic Software Product Lines. In this demonstration
paper, we present the corresponding tool support ProConAR in the form of a Product
Modeler and a Product Configurator. While the Product Modeler is an Angular web
app that splits products (e.g. table) up into atomic parts (e.g. tabletop, table
legs, funnier) and saves it within a configuration model, the Product Configurator
is an Android client that uses the configuration model to place different product
configurations within the environment of the customer. We show technical details
of our ready to use tool-chain ProConAR by describing its implementation and usage
as well as pointing out future research directions.

text: "Modern services consist of modular, interconnected\r\ncomponents, e.g., microservices
forming a service mesh. To\r\ndynamically adjust to ever-changing service demands,
service\r\ncomponents have to be instantiated on nodes across the network.\r\nIncoming
flows requesting a service then need to be routed\r\nthrough the deployed instances
while considering node and link\r\ncapacities. Ultimately, the goal is to maximize
the successfully\r\nserved flows and Quality of Service (QoS) through online service\r\ncoordination.
Current approaches for service coordination are\r\nusually centralized, assuming
up-to-date global knowledge and\r\nmaking global decisions for all nodes in the
network. Such global\r\nknowledge and centralized decisions are not realistic
in practical\r\nlarge-scale networks.\r\n\r\nTo solve this problem, we propose
two algorithms for fully\r\ndistributed service coordination. The proposed algorithms
can be\r\nexecuted individually at each node in parallel and require only\r\nvery
limited global knowledge. We compare and evaluate both\r\nalgorithms with a state-of-the-art
centralized approach in extensive\r\nsimulations on a large-scale, real-world
network topology.\r\nOur results indicate that the two algorithms can compete
with\r\ncentralized approaches in terms of solution quality but require\r\nless
global knowledge and are magnitudes faster (more than\r\n100x)."

text: "Modern services comprise interconnected components,\r\ne.g., microservices
in a service mesh, that can scale and\r\nrun on multiple nodes across the network
on demand. To process\r\nincoming traffic, service components have to be instantiated
and\r\ntraffic assigned to these instances, taking capacities and changing\r\ndemands
into account. This challenge is usually solved with\r\ncustom approaches designed
by experts. While this typically\r\nworks well for the considered scenario, the
models often rely\r\non unrealistic assumptions or on knowledge that is not available\r\nin
practice (e.g., a priori knowledge).\r\n\r\nWe propose a novel deep reinforcement
learning approach that\r\nlearns how to best coordinate services and is geared
towards\r\nrealistic assumptions. It interacts with the network and relies on\r\navailable,
possibly delayed monitoring information. Rather than\r\ndefining a complex model
or an algorithm how to achieve an\r\nobjective, our model-free approach adapts
to various objectives\r\nand traffic patterns. An agent is trained offline without
expert\r\nknowledge and then applied online with minimal overhead. Compared\r\nto
a state-of-the-art heuristic, it significantly improves flow\r\nthroughput and
overall network utility on real-world network\r\ntopologies and traffic traces.
It also learns to optimize different\r\nobjectives, generalizes to scenarios with
unseen, stochastic traffic\r\npatterns, and scales to large real-world networks."

text: In the present work, we provide an electronic structure based method
for the “on-the-fly” determination of vibrational sum frequency generation (v-SFG)
spectra. The predictive power of this scheme is demonstrated at the air-water
interface. While the instantaneous fluctuations in dipole moment are obtained
using the maximally localized Wannier functions, the fluctuations in polarizability
are approximated to be proportional to the second moment of Wannier functions.
The spectrum henceforth obtained captures the signatures of hydrogen bond stretching,
bending, as well as low-frequency librational modes.

text: This is the second part of a project on the foundations of first-principle
calculations of the electron transport in crystals at finite temperatures, aiming
at a predictive first-principles platform that combines ab-initio molecular dynamics
(AIMD) and a finite-temperature Kubo-formula with dissipation for thermally disordered
crystalline phases. The latter are encoded in an ergodic dynamical system (Ω,G,dP),
where Ω is the configuration space of the atomic degrees of freedom, G is the
space group acting on Ω and dP is the ergodic Gibbs measure relative to the G-action.
We first demonstrate how to pass from the continuum Kohn–Sham theory to a discrete
atomic-orbitals based formalism without breaking the covariance of the physical
observables w.r.t. (Ω,G,dP). Then we show how to implement the Kubo-formula, investigate
its self-averaging property and derive an optimal finite-volume approximation
for it. We also describe a numerical innovation that made possible AIMD simulations
with longer orbits and elaborate on the details of our simulations. Lastly, we
present numerical results on the transport coefficients of crystal silicon at
different temperatures.

text: "Peer-Berater*innen nehmen während eines Beratungsgespräches teilweise intuitiv,
teilweise bewusst verschiedene\r\nRollen ein. Dieser Artikel soll einen Beitrag
zur Reflexion über das Spannungsverhältnis zwischen der Experten- und\r\nProzessberatungsrolle
leisten, um die Selbstprofessionalisierung in der Rolleneinnahme zu fördern. Dafür
werden\r\nauf theoretischer Ebene die konträren Arbeitsweisen beleuchtet, auf
denen beide Rollen basieren. Zur Betrachtung\r\nvon möglichen Einflussfaktoren
auf die Rolleneinnahme wird ein selbst entwickeltes Modell präsentiert, welches
zum\r\nAustausch über diese Faktoren motivieren soll. Zuletzt wird eine praktische
Möglichkeit zur gezielten Reflexion über\r\ndie eigene Rolleneinnahme anhand eines
Fragebogens vorgeschlagen."

text: 'Individual grains of chalcopyrite solar cell absorbers can facet in different
crystallographic directions at their surfaces. To gain a deeper understanding
of the junction formation in these devices, we correlate variations in the surface
facet orientation with the defect electronic properties. We use a combined analytical
approach based on scanning tunneling spectroscopy (STS), scanning electron microscopy,
and electron back scatter diffraction (EBSD), where we perform these experiments
on identical surface areas as small as 2 × 2 µm2 with a lateral resolution well
below 50 nm. The topography of the absorber surfaces indicates two main morphological
features: micro-faceted, long basalt-like columns and their short nano-faceted
terminations. Our STS results reveal that the long columns exhibit spectral signatures
typical for the presence of pronounced oxidation-induced surface dipoles in conjunction
with an increased density of electronic defect levels. In contrast, the nano-faceted
terminations of the basalt-like columns are largely passivated in terms of electronic
defect levels within the band gap region. Corresponding crystallographic data
based on EBSD experiments show that the surface of the basalt-like columns can
be assigned to intrinsically polar facet orientations, while the passivated terminations
are assigned to non-polar planes. Ab-initio calculations suggest that the polar
surfaces are more prone to oxidation and resulting O-induced defects, in comparison
to non-polar planes. Our results emphasize the correlation between morphology,
surface facet orientations and surface electronic properties. Furthermore, this
work aids in gaining a fundamental understanding of oxidation induced lateral
inhomogeneities in view of the p-n junction formation in chalcopyrite thin-film
solar cells.'
