text: This paper presents a technique to extend the frequency acquisition range
for bang-bang phase-detector-based clock and data recovery (CDR) circuits without
an additional frequency acquisition loop or lock detection circuit. The per-manent
modulation of the offset current in the CDR's integral branch enhances the acquisition
range by nearly 4 times, covering the entire tuning range of the voltage controlled
oscillator. The increase in power dissipation and the chip area are negligible.
This technique was implemented and measured in a 28 Gbps NRZ bang-bang CDR chip
to confirm the working principle. In addition to the increased acquisition range,
the CDR also surpasses jitter related specifications from the OIF CEI-28G-VSR
standard.

text: We consider a geodesic billiard system consisting of a complete Riemannian
manifold and an obstacle submanifold with boundary at which the trajectories of
the geodesic flow experience specular reflections. We show that if the geodesic
billiard system is hyperbolic on its trapped set and the latter is compact and
non-grazing the techniques for open hyperbolic systems developed by Dyatlov and
Guillarmou can be applied to a smooth model for the discontinuous flow defined
by the non-grazing billiard trajectories. This allows us to obtain a meromorphic
resolvent for the generator of the billiard flow. As an application we prove a
meromorphic continuation of weighted zeta functions together with explicit residue
formulae. In particular, our results apply to scattering by convex obstacles in
the Euclidean plane.

text: "Abstract\r\n For a compact
Riemannian locally symmetric space $\\mathcal M$ of rank 1 and an associated vector
bundle $\\mathbf V_{\\tau }$ over the unit cosphere bundle $S^{\\ast }\\mathcal
M$, we give a precise description of those classical (Pollicott–Ruelle) resonant
states on $\\mathbf V_{\\tau }$ that vanish under covariant derivatives in the
Anosov-unstable directions of the chaotic geodesic flow on $S^{\\ast }\\mathcal
M$. In particular, we show that they are isomorphically mapped by natural pushforwards
into generalized common eigenspaces of the algebra of invariant differential operators
$D(G,\\sigma )$ on compatible associated vector bundles $\\mathbf W_{\\sigma }$
over $\\mathcal M$. As a consequence of this description, we obtain an exact band
structure of the Pollicott–Ruelle spectrum. Further, under some mild assumptions
on the representations $\\tau$ and $\\sigma$ defining the bundles $\\mathbf V_{\\tau
}$ and $\\mathbf W_{\\sigma }$, we obtain a very explicit description of the generalized
common eigenspaces. This allows us to relate classical Pollicott–Ruelle resonances
to quantum eigenvalues of a Laplacian in a suitable Hilbert space of sections
of $\\mathbf W_{\\sigma }$. Our methods of proof are based on representation theory
and Lie theory."

voraus, dass die Eigenschaften des Fluids hinlänglich bekannt sind.Während Fluidkenngrößen,
wie etwa die Schallgeschwindigkeit oder die Scherviskosität, für viele Flüssigkeiten
über weite Bereiche des thermodynamischen Zustandsraums bekannt sind, existieren
für die Volumenviskosität nur eine geringe Anzahl Messdaten.In dieser Arbeit wird
daher ein Messverfahren zur selektiven Bestimmung der Volumenviskosität von Flüssigkeiten,
basierend auf der Absorption von Ultraschallwellen, entwickelt und realisiert.Schwerpunkte
bilden dabei der simulationsgestützte Entwurf von Algorithmen zur Auswertung der
Messsignale sowie die Analyse und Weiterentwicklung einer Messanordnung, basierend
auf dem Puls-Echo-Verfahren. Neben der Absorption im Fluid treten dabei weitere
Effekte (zum Beispiel Beugung oder unvollständige Reflexion) auf, die das akustische
Signal schwächen oder anderweitig beeinflussen. Die Entwicklung von Verfahren
zur Trennung dieser Effekte von der akustischen Absorption bildet daher einen
weiteren Schwerpunkt dieser Arbeit.Abschließend wird die Volumenviskosität aus
der gemessenen akustischen Absorption für unterschiedliche Fluide in verschiedenen
thermodynamischen Zuständen unter Zuhilfenahme anderer bekannter Fluidkenngrößen
bestimmt sowie eine Unsicherheitsbetrachtung durchgeführt.

text: The prerequisite for a complete description of fluid dynamic and acoustic
processes is that all properties of the fluid are known.While fluid parameters
such as the speed of sound or the shear viscosity are known for many liquids over
a wide range of thermodynamic states, only limited measurement data exist for
the bulk viscosity.In this thesis, a measurement method for the selective determination
of the bulk viscosity of liquids, based on the absorption of ultrasonic waves,
is developed and implemented.The focus is on the simulation-driven design of algorithms
for processing the measurement signals as well as the analysis and further development
of a measurement set-up based on the pulse-echo method.In addition to absorption
in the fluid, there are other effects (for example diffraction or incomplete reflection)
that weaken or otherwise influence the acoustic signal.Therefore, the development
of procedures to separate these effects from acoustic absorption is another focus
of this work.The bulk viscosity is determined from the measured acoustic absorption
for different fluids in different thermodynamic states. An uncertainty analysis
of the measured quantities concludes this thesis.

text: The kinetic Brownian motion on the sphere bundle of a Riemannian manifold
M is a stochastic process that models a random perturbation of the geodesic flow.
If M is an orientable compact constantly curved surface, we show that in the limit
of infinitely large perturbation the L2-spectrum of the infinitesimal generator
of a time-rescaled version of the process converges to the Laplace spectrum of
the base manifold.

text: Modular solid-state transformers (SSTs) are a promising technology in converting
power from a 10kV three-phase medium voltage to a lower DC-voltage in the range
of 100…400V to provide pure DC power to applications such as electrolyzers for
hydrogen generation, data centers with a DC power distribution and DC micro grids.
Modular SSTs which can be interpreted as modular multilevel converters with an
isolated DC-DC output stage per module, are designed with redundant modules to
increase reliability. Usually, each of the three arms operates independently,
and therefore, only a fixed number of faulty modules can be compensated in each
arm, even if all modules are operational in the remaining two arms. With the proposed
zero-sequence voltage injection, up to 100% more faulty modules can be compensated
in an arm by employing the same hardware. In addition, module power imbalances
are nearly eliminated by utilizing a fundamental frequency zero-sequence voltage.
A dominant 3rd harmonic zero-sequence voltage injection in combination with the
5th, 7th and several higher order harmonics with adaptive (small) amplitudes minimize
the required arm voltages at steady-state. For nominal operation or symmetrical
faults, the proposed technique is equivalent to the well known Min-Max voltage
injection, which already reduces the peak arm voltage by 13.4% compared to a constant
star point potential. A statistical analysis proves, that the expected number
of tolerable faulty modules of the 1MW SST increases by 12% without the need for
additional hardware.

text: While 2D Gibbsian particle systems might exhibit orientational order resulting
in a lattice-like structure, these particle systems do not exhibit positional
order if the interaction between particles satisfies some weak assumptions. Here
we investigate to which extent particles within a box of size may fluctuate from
their ideal lattice position. We show that particles near the center of the box
typically show a displacement at least of order . Thus we extend recent results
on the hard disk model to particle systems with fairly arbitrary particle spins
and interaction. Our result applies to models such as rather general continuum
Potts type models, e.g. with Widom–Rowlinson or Lenard-Jones-type interaction.

text: "Consider a set of jobs connected to a directed acyclic task graph with a\r\nfixed
source and sink. The edges of this graph model precedence constraints and\r\nthe
jobs have to be scheduled with respect to those. We introduce the Server\r\nCloud
Scheduling problem, in which the jobs have to be processed either on a\r\nsingle
local machine or on one of many cloud machines. Both the source and the\r\nsink
have to be scheduled on the local machine. For each job, processing times\r\nboth
on the server and in the cloud are given. Furthermore, for each edge in\r\nthe
task graph, a communication delay is included in the input and has to be\r\ntaken
into account if one of the two jobs is scheduled on the server, the other\r\nin
the cloud. The server can process jobs sequentially, whereas the cloud can\r\nserve
as many as needed in parallel, but induces costs. We consider both\r\nmakespan
and cost minimization. The main results are an FPTAS with respect for\r\nthe makespan
objective for a fairly general case and strong hardness for the\r\ncase with unit
processing times and delays."
