text: Die vorliegende Dissertation beschreibt das Konzept und den Entwicklungsprozess
eines Lichtsignalanlagenregelungssystems bis zur Realumsetzung. Das Regelungssystem,
welches im Rahmen des Pilotprojekts Schlosskreuzung entstanden ist, besteht dabei
aus zwei untereinander abgestimmten Methoden zur Echtzeit-Verkehrsrekonstruktion
und zur modellprädiktiven Regelung des Verkehrssystems anhand der vorhandenen
Lichtsignalanlagen. Die Echtzeit-Verkehrsrekonstruktion approximiert dabei simulationsbasiert
den aktuellen Verkehrszustand anhand gegebener Messdaten über dynamische Verkehrszuweisungen.
Die entwickelte mehrstufige Lichtsignalanlagenregelung nutzt ein Fuzzy-System
zur Phasenvorauswahl, um anschließend über eine modellprädiktive Regelung das
nichtlineare Problem mit dem Ergebnis der optimalen Kombinationen von Phasen und
Schaltzeitpunkten zu lösen. Das Regelungssystem wird in dieser Arbeit anhand eines
ausgewählten Verkehrsgebiets zunächst rein simulativ getestet und mit dem vorliegenden
Bestandsverfahren verglichen. Im Anschluss an die prototypische Inbetriebnahme
wird dieser Vergleich durch die Feldtests abgeschlossen. Entsprechende Ergebnisse
zeigen das große Potential der Entwicklung hinsichtlich der Reduktion von Kriterien
wie Emissionen oder Wartezeiten und gleichzeitig den Handlungsbedarf für eine
standardmäßige Nutzung.

text: This dissertation describes the concept and the development process of a traffic
signal control system up to the real implementation.The control system, which
was developed in the context of the Pilotprojekt Schlosskreuzung, consists of
two mutually coordinated methods for real-time traffic reconstruction and for
model-predictive control of the traffic system based on the existing traffic light
systems.The real-time traffic reconstruction approximates the current traffic
state simulation-based using given measurement data via dynamic traffic assignments.The
designed multi-stage traffic signal control system uses a fuzzy-system for phase
preselection and subsequently employs model predictive control to solve the nonlinear
problem resulting in the optimal combinations of phases and switching times.In
this work, the control system is first tested purely simulatively on the basis
of a selected traffic area and compared with the existing inventory method.Following
the prototypical commissioning, this comparison is finalised by field tests.Corresponding
results show the great potential of the development with regard to the reduction
of criteria such as emissions or waiting times and at the same time the need for
action for use as standard.

text: Controlling the intensity of emitted light and charge current is the basis
of transferring and processing information1. By contrast, robust information storage
and magnetic random-access memories are implemented using the spin of the carrier
and the associated magnetization in ferromagnets2. The missing link between the
respective disciplines of photonics, electronics and spintronics is to modulate
the circular polarization of the emitted light, rather than its intensity, by
electrically controlled magnetization. Here we demonstrate that this missing link
is established at room temperature and zero applied magnetic field in light-emitting
diodes2,3,4,5,6,7, through the transfer of angular momentum between photons, electrons
and ferromagnets. With spin–orbit torque8,9,10,11, a charge current generates
also a spin current to electrically switch the magnetization. This switching determines
the spin orientation of injected carriers into semiconductors, in which the transfer
of angular momentum from the electron spin to photon controls the circular polarization
of the emitted light2. The spin–photon conversion with the nonvolatile control
of magnetization opens paths to seamlessly integrate information transfer, processing
and storage. Our results provide substantial advances towards electrically controlled
ultrafast modulation of circular polarization and spin injection with magnetization
dynamics for the next-generation information and communication technology12, including
space–light data transfer. The same operating principle in scaled-down structures
or using two-dimensional materials will enable transformative opportunities for
quantum information processing with spin-controlled single-photon sources, as
well as for implementing spin-dependent time-resolved spectroscopies.

text: 'In this paper new semiparametric generalized autoregressive conditional heteroscedasticity
(GARCH) models with long memory are introduced. A multiplicative decomposition
of the volatility into a conditional component and an unconditional component
is assumed. The estimation of the latter is carried out by means of a data-driven
local polynomial smoother. According to the revised recommendations by the Basel
Committee on Banking Supervision to measure market risk in the banks’ trading
books, these new semiparametric GARCH models are applied to obtain rolling one-step
ahead forecasts for the value-at-risk and expected shortfall (ES) for market risk
assets. Standard regulatory traffic-light tests and a newly introduced traffic-light
test for the ES are carried out for all models. In addition, model performance
is assessed via a recently introduced model selection criterion. The practical

text: In this paper new semiparametric GARCH models with long memory are in- troduced.
The estimation of the nonparametric scale function is carried out by an adapted
version of the SEMIFAR algorithm (Beran et al., 2002). Recurring on the revised
recommendations by the Basel Committee to measure market risk in the banks' trading
books (Basel Committee on Banking Supervision, 2013), the semi- parametric GARCH
models are applied to obtain rolling one-step ahead forecasts for the Value at
Risk (VaR) and Expected Shortfall (ES) for market risk assets. In addition, standard
regulatory traffic light tests (Basel Committee on Banking Supervision, 1996)
and a newly introduced traffic light test for the ES are carried out for all models.
The practical relevance of our proposal is demonstrated by a comparative study.
Our results indicate that semiparametric long memory GARCH models are an attractive
alternative to their conventional, parametric counterparts.

text: The preparation of hierarchical and sophisticated particle architectures for
mimicking structural colors known from nature still remains a challenge. In this
study, the preparation of novel opal and double-inverse opal films based on thermally
treated metallopolymer core particles with a silica shell is described. Thermal
treatment leads to the formation of magnetic nanorattle-type particles. The main
challenge of artificial particles is to ensure sufficient dispersibility after
several synthetic steps. Especially silica particles providing surface hydroxyl
groups tend to sinter at high temperatures leading to agglomeration. We present
the introduction of trimethyl ethoxy silane (TMES) as an excellent functionalization
reagent as the key reaction step. The necessity and success of functionalization
are investigated by transmission electron microscopy (TEM) and zeta potential
measurements. Importantly, solid state NMR techniques are employed to gain deeper
insights into the chemical structure of the surface-attached reagent. Finally,
by this convenient functionalization the preparation of elastomeric opal films
and double-inverse opal films is proven successful revealing excellent optical
film properties. Moreover, magnetic properties of these novel films are investigated
by using magnetic force microscopy (MFM). The herein established route is expected
to pave the way for the preparation of a variety of advanced and stimuli-responsive
optical materials.

text: 'In order to avoid over-regulation, some countries have experimented with
what might be called threat-based regulation. The idea is - similarly to the contestable
market model - that actual regulation may not be necessary as long as the threat
of regulation is credible. In that case, so the idea, even monopolies will abstain
from setting monopolistic prices in order to avoid being regulated. As experience
from Germany and New Zealand has demonstrated, there are quite a number of problems
associated with threat-based regulatory systems. The most significant problem
has turned out to be the likely under-regulation and according welfare losses
from market power, and in this context, a critical issue that has been identified
is the credibility of the regulatory threat. If the threat of regulation is not
credible, a light-handed regulatory regime (LHRR) amounts to leaving monopolistic
firms unregulated, clearly an undesirable situation from a welfare point of view.
This failure of threat-based regulatory systems results from potential free-rider
problems associated with good corporate behaviour (as in the case of Germany''s
electricity market) as well as the lack of credibility of the threat either because
of the weakness of the enforcement authorities or due to political constraints.
Furthermore, a problem emerges if exercising the threat of regulation implies
an abandonment of the LHRR and a corresponding substitution with heavy-handed
ex ante regulation. An innovative way out of this dilemma has been the quasi-automatic
threshold system originally designed for New Zealand''s electricity distribution
networks, which aims at simulating the pressures that companies would face in
competitive markets. '

text: Piezoelectric transformers are well known since the publication of some patent
applications at the end of the 1950s. But until today their only business use
lies in the field of backlighting systems for LCDs. Due to key features as light-weight,
flatness, high step-up at low volume and high efficiency piezoelectric transformers
should be usable in a much broader range of applications. This contribution returns
to mind their operating principle, shows how to model and to develop such devices
as well as give some aspects for development trends that will lead to further
applications.
