text: Requirements for energy distribution networks are changing fast due to the
growing share of renewable energy, increasing electrification, and novel consumer
and asset technologies. Since uncertainties about future developments increase
planning difficulty, flexibility potentials such as synergies between the electricity,
gas, heat, and transport sector often remain unused. In this paper, we therefore
present a novel module-based concept for a decision support system that helps
distribution network planners to identify cross-sectoral synergies and to select
optimal network assets such as transformers, cables, pipes, energy storage systems
or energy conversion technology. The concept enables long-term transformation
plans and supports distribution network planners in designing reliable, sustainable
and cost-efficient distribution networks for future demands.

text: Ein zentraler Aspekt bei der Untersuchung dynamischer Systeme ist die Analyse
ihrer invarianten Mengen wie des globalen Attraktors und (in)stabiler Mannigfaltigkeiten.
Insbesondere wenn das zugrunde liegende System von einem Parameter abhängt, ist
es entscheidend, sie im Bezug auf diesen Parameter effizient zu verfolgen. Für
die Berechnung invarianter Mengen stützen wir uns für ihre Approximation auf numerische
Algorithmen. Typischerweise können diese Methoden jedoch nur auf endlich-dimensionale
dynamische Systeme angewendet werden. In dieser Arbeit präsentieren wir daher
einen numerischen Rahmen für die globale dynamische Analyse unendlich-dimensionaler
Systeme. Wir werden Einbettungstechniken verwenden, um das core dynamical system
(CDS) zu definieren, welches ein dynamisch äquivalentes endlich-dimensionales
System ist.Das CDS wird dann verwendet, um eingebettete invariante Mengen, also
eins-zu-eins Bilder, mittels Mengen-orientierten numerischen Methoden zu approximieren.
Bei der Konstruktion des CDS ist es entscheidend, eine geeignete Beobachtungsabbildung
auszuwählen und die geeignete inverse Abbildung zu entwerfen. Dazu werden wir
geeignete numerische Implementierungen des CDS für DDEs und PDEs vorstellen. Für
eine nachfolgende geometrische Analyse der eingebetteten invarianten Menge betrachten
wir eine Lerntechnik namens diffusion maps, die ihre intrinsische Geometrie enthüllt
sowie ihre Dimension schätzt. Schließlich wenden wir unsere entwickelten numerischen
Methoden an einigen bekannten unendlich-dimensionale dynamischen Systeme an, wie
die Mackey-Glass-Gleichung, die Kuramoto-Sivashinsky-Gleichung und die Navier-Stokes-Gleichung.

text: One central aspect in the study of dynamical systems is the analysis of its
invariant sets such as the global attractor and (un)stable manifolds. In particular,
when the underlying system depends on a parameter it is crucial to efficiently
track those set with respect to this parameter. For the computation of invariant
sets we rely on numerical algorithms for their approximation but typically those
tools can only be applied to finite-dimensional dynamical systems. Thus, in thesis
we present a numerical framework for the global dynamical analysis of infinite-dimensional
systems. We will use embedding techniques for the definition of the core dynamical
system (CDS) which is a dynamically equivalent finite-dimensional system. The
CDS is then used for the approximation of related embedded invariant sets, i.e,
one-to-one images, by set-oriented numerical methods. For the construction of
the CDS it is crucial to choose an appropriate observation map and to design its
corresponding inverse. Therefore, we will present suitable numerical realizations
of the CDS for DDEs and PDEs. For a subsequent geometric analysis of the embedded
invariant set we will consider a manifold learning technique called diffusion
maps which reveals its intrinsic geometry and estimates its dimension. Finally,
we apply our develop numerical tools on some well-known infinite-dimensional dynamical
systems such as the Mackey-Glass equation, the Kuramoto-Sivashinsky equation and
the Navier-Stokes equation.

text: 'Fault coverage analysis and fault simulation are well-established methods
for the qualification of test vectors in hardware design. However, their role
in virtual prototyping and the correlation to later steps in the design process
need further investigation. We introduce a metric for RISC-V instruction and register
coverage for binary software. The metric measures if RISC-V instruction types
are executed and if GPRs, CSRs, and FPRs are accessed. The analysis is applied
by the means of a virtual prototype which is based on an abstract instruction
and register model with direct correspondence to their bit level representation.
In this context, we analyzed three different openly available test suites: the
RISC-V architectural testing framework, the RISC-V unit tests, and programs which
are automatically generated by the RISC-V Torture test generator. We discuss their
tradeoffs and show that by combining them to a unified test suite we can arrive
at a 100% GPR and FPR register coverage and a 98.7% instruction type coverage.'

text: We show that narrow trenches in a high-contrast silicon-photonics slab can
act as lossless power dividers for semi-guided waves. Reflectance and transmittance
can be easily configured by selecting the trench width. At sufficiently high angles
of incidence, the devices are lossless, apart from material attenuation and scattering
due to surface roughness. We numerically simulate a series of devices within the
full 0-to-1-range of splitting ratios, for semi-guided plane wave incidence as
well as for excitation by focused Gaussian wave bundles. Straightforward cascading
of the trenches leads to concepts for 1×M-power dividers and a polarization beam
splitter.

text: "Macrodiversity is a key technique to increase the capacity of mobile networks.
It can be realized using coordinated multipoint (CoMP), simultaneously connecting
users to multiple overlapping cells. Selecting which users to serve by how many
and which cells is NP-hard but needs to happen continuously in real time as users
move and channel state changes. Existing approaches often require strict assumptions
about or perfect knowledge of the underlying radio system, its resource allocation
scheme, or user movements, none of which is readily available in practice.\r\n\r\nInstead,
we propose three novel self-learning and self-adapting approaches using model-free
deep reinforcement learning (DRL): DeepCoMP, DD-CoMP, and D3-CoMP. DeepCoMP leverages
central observations and control of all users to select cells almost optimally.
DD-CoMP and D3-CoMP use multi-agent DRL, which allows distributed, robust, and
highly scalable coordination. All three approaches learn from experience and self-adapt
to varying scenarios, reaching 2x higher Quality of Experience than other approaches.
They have very few built-in assumptions and do not need prior system knowledge,
making them more robust to change and better applicable in practice than existing
approaches."

text: "Die Werkzeugdemonstration des QEMU Timing Analyzers (QTA) stellt eine Erweiterung
des quelloffenen CPU Emulators QEMU zur Simulation von Softwareprogrammen und
deren Worst-Case Zeitverhaltens vor, das durch eine statische Zeitanalyse vorher
aus dem Softwareprogramm extrahiert wurde. Der Ablauf der Analyse gliedert sich
in mehrere Schritte: Zunächst wird für das zu simulierende Binärprogramm eine
WCET-Analyse mit aiT durchgeführt. Im Preprocessing des aiT-Reports wird daraufhin
ein WCET-annotierter Kontrollflussgraph erzeugt. Dabei entsprechen die Knoten
im Kontrollflussgraph den aiT-Blöcken und die Kanten dem jeweiligen Worst-Case-Zeitverbrauch,
um das Programm im aktuellen Ausführungskontext vom Quell- bis zum Zielblock laufen
zu lassen. Nach dem Preprocessing werden Binärprogramm und der zuvor erzeugte,
zeitannotierte Kontrollflussgraph von QEMU geladen und gemeinsam simuliert.\r\n\r\nDie
Implementierung des QTA basiert auf der Standard TGI Plugin API (Tiny Code Generator
Plugin API), die seit Ende 2019 mit QEMU V4.2 verfügbar ist. Dieses API erlaubt
die Entwicklung von versionsunabhängigen QEMU-Erweiterungen. Die QEMU-QTA-Erweiterung
wird zum Zeitpunkt der Werkzeugdemonstration inklusive des ait2qta-Preprozessors
unter github.com im Quellcode frei verfügbar sein.\r\n\r\nDie Demonstration geht
von einer existierenden aiT-Analyse eines für TriCore© kompilierten binären Softwareprograms
aus, erläutert das Kontrollflusszwischenformat und zeigt die zeitannotierte Simulation
der Software."

text: A locally compact contraction group is a pair (G,α), where G is a locally
compact group and α:G→G an automorphism such that αn(x)→e pointwise as n→∞. We
show that every surjective, continuous, equivariant homomorphism between locally
compact contraction groups admits an equivariant continuous global section. As
a consequence, extensions of locally compact contraction groups with abelian kernel
can be described by continuous equivariant cohomology. For each prime number p,
we use 2-cocycles to construct uncountably many pairwise non-isomorphic totally
disconnected, locally compact contraction groups (G,α) which are central extensions0→Fp((t))→G→Fp((t))→0
of the additive group of the field of formal Laurent series over Fp=Z/pZ by itself.
By contrast, there are only countably many locally compact contraction groups
(up to isomorphism) which are torsion groups and abelian, as follows from a classification
of the abelian locally compact contraction groups.

text: "In den letzten Jahren haben sich Software-Ökosysteme als neue, erfolgreiche
Geschäftsform etabliert. Unternehmen agieren hierbei als Anbieter von Software-Plattformen,
auf denen Drittanbieter Softwarelösungen für den Markt anbieten können. Etablierte
Beispiele sind hierbei sogenannte App-Stores, die z.B. von Google oder Apple angeboten
werden.\r\n\r\nBeim Aufbau von Software-Ökosystemen müssen vom Plattformanbieter
viele architektonische Entwurfsentscheidungen getroffen werden. Bisher gibt es
keine Architekturrichtlinien und -werkzeuge, die den Entwurf einer Ökosystemarchitektur
unterstützen. Dadurch fehlt hier systematisches, wiederverwendbares Wissen. Plattformanbieter
müssen auf ad-hoc Entscheidungen zurückgreifen. Dies kann dann zu Problemen im
Betrieb der Software-Plattformen führen, zu erhöhten Ausfallrisiken und Mehrkosten.\r\n\r\nDer
Mangel an Architekturwissen manifestiert sich konkret in zwei Gruppen von Herausforderungen:
Erstens fehlt eine Wissensbasis zu Architekturalternativen und zweitens fehlt
es an methodischem Wissen zu Entwicklung und Betrieb von Software-Ökosystemen.
Eine Architekturwissensbasis würde Orientierungshilfen zu den Bestandteilen von
Software-Ökosystemen und deren Abhängigkeiten geben, während methodisches Wissen
die Erstellung dieser Systeme erleichtern würde.\r\n\r\nIn der Dissertation werden
diese Herausforderungen durch die Entwicklung des Frameworks SecoArc für die Modellierung
von Software-Ökosystemen angegangen. Der Beitrag der Dissertation ist zweifach:
\r\n1.\tDas SecoArc-Framework umfasst eine Architekturwissensbasis, die wiederverwendbare
Architekturentwurfsentscheidungen\r\nvon Software-Ökosystemen enthält. Die Wissensbasis
wurde entwickelt, indem das Architekturwissen bestehender Ökosysteme sowie aus
existierender Fachliteratur ermittelt wurde und in einer Produktlinie für Software-Ökosysteme
konsolidiert wurde. Die Produktlinie umfasst architektonische Gemeinsamkeiten
und Variabilitäten von Software-Ökosystemen. \r\n2.\tDas SecoArc-Framework liefert
methodisches Wissen, um die Ökosystemarchitektur in Modellen zu entwerfen und
zu analysieren. Dieses Wissen wurde entwickelt, indem drei Architekturmuster identifiziert
wurden. Jedes Muster erfasst unterschiedliche Beziehungen zwischen architektonischen
Entwurfsentscheidungen zu den Qualitätsmerkmalen einer Ökosystemgesundheit und
der Erreichung von Geschäftszielen. \r\n\r\nDie Architekturmuster und die Produktlinie
wurden dazu genutzt, ein Modellierungsframework zu entwickeln und in Form eines
Prototypen umzusetzen, welches einen Entwurfsprozess, eine Modellierungssprache
und eine Architekturanalysetechnik umfasst. Es erleichtert das Modellieren, Analysieren
und Vergleichen von Ökosystemarchitekturen.\r\n\r\nDie Ergebnisse der Dissertation
wurden im Rahmen von zwei Studien evaluiert. In der ersten Validierungsstudie
wurden das Framework sowie der Prototyp verwendet, um zwei alternative Ökosystemarchitekturen
zu entwerfen und zu analysieren. In der zweiten Studie wurde eine Analyse von
existierenden Ökosystemen basierend auf den architektonischen Variabilitäten des
Frameworks durchgeführt."

text: "Access to precise meteorological data is crucial to be able to plan and install
renewable energy systems \r\nsuch as solar power plants and wind farms. In case
of solar energy, knowledge of local irradiance and air temperature \r\nvalues
is very important. For this, various methods can be used such as installing local
weather stations or using \r\nmeteorological data from different organizations
such as Meteonorm or official Deutscher Wetterdienst (DWD). An \r\nalternative
is to use satellite reanalysis datasets provided by organizations like the National
Aeronautics and Space \r\nAdministration (NASA) and European Centre for Medium-Range
Weather Forecasts (ECMWF). In this paper the \r\n“Modern-Era Retrospective analysis
for Research and Applications” dataset version 2 (MERRA-2) will be presented,
\r\nand its performance will be evaluated by comparing it to locally measured
datasets provided by Meteonorm and DWD. \r\nThe analysis shows very high correlation
between MERRA-2 and local measurements (correlation coefficients of 0.99) \r\nfor
monthly global irradiance and air temperature values. The results prove the suitability
of MERRA-2 data for \r\napplications requiring long historical data. Moreover,
availability of MERRA-2 for the whole world with an acceptable \r\nresolution
makes it a very valuable dataset."

text: "Efficiencies and energy yields of microinverters available on the market
during 2014‒2021 have been \r\nmeasured, compared, and ranked. Conversion efficiencies
as a function of load have been measured indoors with high \r\naccuracy and ranked
according to Euro- and CEC weightings. Energy yields have been measured outdoors
via \r\nidentical and calibrated crystalline silicon PV modules of 215 Wp (until
2020) and 360 Wp (starting 2021). Inverters \r\nwith two inputs have been fed
by two of those modules. DC input, AC power output and energy yield of each micro\x02inverter
have been recorded by individual calibrated electricity meters. CEC and EU efficiency
rankings have been \r\ncomputed and compared. To assess the influence of PV module
size, two extremes have been investigated: A rather \r\nsmall module with 215
Wp - as it has been used 10 years ago, and a brand-new module (2021) offering
360 Wp. Both \r\ntypes of modules contain 60 solar cells in series connection.
Appling the low-power modules, the challenge for the \r\ndifferent micro-inverters
has been during weak-light conditions, using the high-power modules, some inverters
\r\ntemporarily reach their power limits and yield is reduced. A method using
a reference configuration of inverter & \r\nmodule and a linear equation y = ax
+ b resulting in the actual yield, any module & inverter configuration can be
\r\ncharacterized by just the coefficients a and b."

text: Fast-growing energy demand of the world makes the researchers focus
on finding new energy sources or optimizing already-developed approaches. For
an efficient use of solar and wind energy in an energy system, correct design
and sizing of a power system is of high importance and improving or optimizing
the process of data obtaining for this purpose leads to higher performance and
lower cost per unit of energy. It is essential to have the most precise possible
estimation of solar and wind energy potential and other local weather parameters
in order to fully feed the demand and avoid extra costs. There are various methods
for obtaining local data, such as local measurements, official organizational
data, satellite obtained, and reanalysis data. In this paper, the Modern-Era Retrospective
analysis for Research and Applications dataset version 2 (MERRA-2) dataset provided
by NASA is introduced and its performance is evaluated by comparison to various
locally measured datasets offered by meteorological institutions such as Meteonorm
and Deutscher Wetterdienst (DWD, or Germany’s National Meteorological Service)
around the world. After comparison, correlation coefficients from 0.95 to 0.99
are observed for monthly global horizontal irradiance values. In the case of air
temperature, correlation coefficients of 0.99 and for wind speed from 0.81 to
0.99 are observed. High correlation with ground measurements and relatively low
errors are confirmed, especially for irradiance and temperature values, that makes
MERRA-2 a valuable dataset, considering its world coverage and availability.

text: This paper investigates an ultra-broadband sampling technique based on charge
sampling using an Integrate-and-Hold Circuit (IHC) and ultra-short integration
times. The charge sampling technique is mathematically analyzed in detail and
compared to conventional switched-capacitor sampling. The mathematical analysis
allows to predict the sampler bandwidth as well as the degradation of sampling
precision due to analog circuit impairments such as integrator gain error, integration
capacitor leakage, hold-mode droop, thermal noise, and clock jitter. Furthermore,
design, simulation, and measurement results of an ultra-broadband charge sampler
IC in SiGe BiCMOS technology are presented. The charge sampler IC achieves a 1dB
bandwidth of 70 GHz. A resolution of better than 5.9 effective number of bits
(ENOB) is measured from 0 to 70 GHz at a sampling rate of 5 GS/s. The results
suggest that charge sampling using an IHC is a viable concept for ultra-broadband
sampling.
