text: In the development of model predictive controllers for PDE-constrained problems,
the use of reduced order models is essential to enable real-time applicability.
Besides local linearization approaches, proper orthogonal decomposition (POD)
has been most widely used in the past in order to derive such models. Due to the
huge advances concerning both theory as well as the numerical approximation, a
very promising alternative based on the Koopman operator has recently emerged.
In this chapter, we present two control strategies for model predictive control
of nonlinear PDEs using data-efficient approximations of the Koopman operator.
In the first one, the dynamic control system is replaced by a small number of
autonomous systems with different yet constant inputs. The control problem is
consequently transformed into a switching problem. In the second approach, a bilinear
surrogate model is obtained via a convex combination of these autonomous systems.
Using a recent convergence result for extended dynamic mode decomposition (EDMD),
convergence of the reduced objective function can be shown. We study the properties
of these two strategies with respect to solution quality, data requirements, and
complexity of the resulting optimization problem using the 1-dimensional Burgers
equation and the 2-dimensional Navier–Stokes equations as examples. Finally, an
extension for online adaptivity is presented.

text: The control of complex systems is of critical importance in many branches
of science, engineering, and industry, many of which are governed by nonlinear
partial differential equations. Controlling an unsteady fluid flow is particularly
important, as flow control is a key enabler for technologies in energy (e.g.,
wind, tidal, and combustion), transportation (e.g., planes, trains, and automobiles),
security (e.g., tracking airborne contamination), and health (e.g., artificial
hearts and artificial respiration). However, the high-dimensional, nonlinear,
and multi-scale dynamics make real-time feedback control infeasible. Fortunately,
these high- dimensional systems exhibit dominant, low-dimensional patterns of
activity that can be exploited for effective control in the sense that knowledge
of the entire state of a system is not required. Advances in machine learning
have the potential to revolutionize flow control given its ability to extract
principled, low-rank feature spaces characterizing such complex systems.We present
a novel deep learning modelpredictive control framework that exploits low-rank
features of the flow in order to achieve considerable improvements to control
performance. Instead of predicting the entire fluid state, we use a recurrent
neural network (RNN) to accurately predict the control relevant quantities of
the system, which are then embedded into an MPC framework to construct a feedback
loop. In order to lower the data requirements and to improve the prediction accuracy
and thus the control performance, incoming sensor data are used to update the
RNN online. The results are validated using varying fluid flow examples of increasing
complexity.

text: "In recent years, the success of the Koopman operator in dynamical systems\r\nanalysis
has also fueled the development of Koopman operator-based control\r\nframeworks.
In order to preserve the relatively low data requirements for an\r\napproximation
via Dynamic Mode Decomposition, a quantization approach was\r\nrecently proposed
in [Peitz & Klus, Automatica 106, 2019]. This way, control\r\nof nonlinear dynamical
systems can be realized by means of switched systems\r\ntechniques, using only
a finite set of autonomous Koopman operator-based\r\nreduced models. These individual
systems can be approximated very efficiently\r\nfrom data. The main idea is to
transform a control system into a set of\r\nautonomous systems for which the optimal
switching sequence has to be computed.\r\nIn this article, we extend these results
to continuous control inputs using\r\nrelaxation. This way, we combine the advantages
of the data efficiency of\r\napproximating a finite set of autonomous systems
with continuous controls. We\r\nshow that when using the Koopman generator, this
relaxation --- realized by\r\nlinear interpolation between two operators --- does
not introduce any error for\r\ncontrol affine systems. This allows us to control
high-dimensional nonlinear\r\nsystems using bilinear, low-dimensional surrogate
models. The efficiency of the\r\nproposed approach is demonstrated using several
examples with increasing\r\ncomplexity, from the Duffing oscillator to the chaotic
fluidic pinball."

text: We analyze the actual behavior of agents in a matching mechanism, using data
from a clearinghouse at the Faculty of Business Administration and Economics at
a German university, where a variant of the Boston mechanism is used. We supplement
this data with data generated in a survey among the students who participated
in the clearinghouse. We find that under the current mechanism over 74% of students
act strategically by misrepresenting at least one of their preferences. Nevertheless,
not all students are able to improve their outcome by doing so. We show that this
is mainly due to the incomplete information of students and naiveté. Sophisticated
students actually reach significantly better outcomes than naive students. Thus,
we find evidence that naive students are exploited by sophisticated students in
an incomplete information setting.

text: "Softwarization facilitates the introduction of smart\r\nmanufacturing applications
in the industry. Manifold devices\r\nsuch as machine computers, Industrial IoT
devices, tablets,\r\nsmartphones and smart glasses are integrated into factory
networks\r\nto enable shop floor digitalization and big data analysis. To\r\nhandle
the increasing number of devices and the resulting traffic,\r\na flexible and
scalable factory network is necessary which can be\r\nrealized using softwarization
technologies like Network Function\r\nVirtualization (NFV). However, the security
risks increase with\r\nthe increasing number of new devices, so that cyber security
must\r\nalso be considered in NFV-based networks.\r\n\r\nTherefore, extending
our previous work, we showcase threat\r\ndetection using a cloud-native NFV-driven
intrusion detection\r\nsystem (IDS) that is integrated in our industrial-specific
network\r\nservices. As a result of the threat detection, the affected network\r\nservice
is put into quarantine via automatic network reconfiguration.\r\nWe use the 5GTANGO
service platform to deploy our\r\ndeveloped network services on Kubernetes and
to initiate the\r\nnetwork reconfiguration."

text: Diagrammatisches Schlie{\ss}en wird im Zusammenhang mit dem Lernen von Mathmematik
und ihrer Symbolsprache als wesentliche Theorie der Wissenskonstruktion diskutiert.
Dabei wird h{\"{a}}ufig davon ausgegangen, dass die Wissenskonstruktion im Sinne
diagrammatischen Schlie{\ss}ens erfolgt. Deskriptive Rekonstruktionen diagrammatischen
Schlie{\ss}ens bei Lernenden stellen jedoch ein Desiderat der mathematikdidaktischen
Forschung dar. Der vorliegende Beitrag befasst sich mit der Fragestellung, wie
sich diagrammatisches Schlie{\ss}en bei Lernenden rekonstruieren l{\"{a}}sst.
Als m{\"{o}}gliche Werkzeuge f{\"{u}}r eine solche Rekonstruktion werden Toulmins
Argumentationsschema und Vergnauds Schema-Begriff exemplarisch angewandt, um das
diagrammatische Schlie{\ss}en eines Sch{\"{u}}lerpaars beim Einstieg in die Subtraktion
negativer Zahlen zu rekonstruieren. Abschlie{\ss}end wird die tats{\"{a}}chliche
Eignung der beiden Ans{\"{a}}tze zur Rekonstruktion diagrammatischen Schlie{\ss}ens
diskutiert.

text: "We study the structure of power networks in consideration of local protests
against certain\r\npower lines (’not-in-my-backyard’). An application of a network
formation game is used to\r\ndetermine whether or not such protests arise. We
examine the existence of stable networks and\r\ntheir characteristics, when no
player wants to make an alteration. Stability within this game is\r\nonly reached
if each player is sufficiently connected to a power source but is not linked to
more\r\nplayers than necessary. In addition we introduce an algorithm that creates
a stable network."

text: AbstractLaser surface treatment of metals
is one option to improve their properties for adhesive bonding. In this paper,
a pulsed YVO4 Laser source with a wavelength of 1064 nm and a maximum power of
25 W was utilized to increase the surface area of the steel HCT490X in order to
improve its bonding properties with a carbon fibre reinforced polymer (CFRP).
Investigated was the influence of the scanning speed of the laser source on the
bonding properties. For this purpose, the steel surfaces were ablated at a scanning
speed between 1500 and 4500 mm/s. Afterwards the components were bonded with the
adhesive HexBond™ 677. After lap shear tests were carried out on the specimen,
the surfaces were inspected using scanning electron microscopy (SEM). The experiments
revealed that the bonding quality can be improved with a high scanning speed,
even when the surface is not completely ablated.
