text: Designprozesse von Schallwandlern werden durch zunehmende Rechenkapazitäten
immer mehr durch simulative Betrachtungen unterstützt. Dabei ist vor allem die
Wahl der Materialparameter der verwendeten Materialien wichtig für ein realitätsnahes
Simulationsergebnis. Bei Schallwandlern werden häufig Piezokeramiken als aktive
Elemente genutzt, welche sich durch eine Verkopplung mechanischer und elektrischer
Eigenschaften auszeichnen. Zur Bestimmung ihrer Materialparameter stellt der IEEE
Standard on Piezoelectricity ein standardisiertes Verfahren dar. Dazu sind fünf
Impedanzmessungen an vier unterschiedlich gefertigten Probekörpergeometrien notwendig.
Da an jedem einzelnen Probekörper nur eine Untermenge aller notwendigen Materialparameter
bestimmt werden kann, werden diese dann zu einem kompletten Materialparametersatz
zusammengefügt. Aufgrund der unterschiedlichen Prozessbedingungen, bei denen die
jeweiligen Probekörper hergestellt werden, ist dieser Materialparametersatz jedoch
inkonsistent und kann nie das Verhalten einer einzelnen Probe beschreiben. Daher
wird in der vorliegenden Arbeit ein Messverfahren entwickelt, mit dem es möglich
ist, alle relevanten Materialparameter unter besonderer Berücksichtigung von Dämpfung
an einem einzelnen Probekörper allein durch Impedanzmessungen zu bestimmen. Als
Probekörper wird dazu eine in der Anwendung häufig verwendete Scheibengeometrie
verwendet. Um eine hinreichend hohe Sensitivität auf alle Materialparameter zu
gewährleisten, wird diese mit einer optimierten Elektrodentopologie gefertigt.
Da in diesem Fall keine analytische Betrachtung mehr möglich ist, wird das Messverfahren
durch einen inversen Ansatz realisiert.

text: Design processes of ultrasonic transducers become increasingly simulation-driven
due to rising computational capabilities. Therewithin, the choice of the material
parameters for modelling the materials used is particularly important for a realistic
simulation result. Piezoceramics, which couple mechanic and electrical properties,
are often used as active elements in ultrasonic transducers.The IEEE Standard
on Piezoelectricity is a standardised procedure for determining these parameters
that requires five impedance measurements on four piezocermics of different geometry.
Since only a subset of all necessary material parameters can be determined for
each individual specimen, these are then combined to form a complete set of material
parameters. Due to different processing conditions for each specimen, this set
of material parameters is inconsistent and cannot describe the behaviour of a
single specimen appropriately. Therefore, in the present thesis, a method is developed
with enables the determination of all relevant material parameters including damping
on a single piezocermic by means of electrical impedance measurements alone. A
piezoelectric ceramic with disc-shaped geometry, which is frequently used in applications,
is used as a specimen.In order to ensure a sufficiently high sensitivity to all
material parameters, it is manufactured with an optimised electrode topology.
Because in this case analytical solutions, which relate the measurement quantities
to the material parameters, do not exist, the measurement method is implemented
using an inverse approach.

text: The progress in numerical methods and simulation tools promotes the use of
inverse problems in material characterisation problems. A newly developed procedure
can be used to identify the behaviour of piezoceramic discs over a wide frequency
range using a single specimen via fitting simulated and measured impedances by
optimising the underlying material parameters. Since there is no generally accepted
damping model for piezoelectric ceramics, several mechanical damping models are
examined for the material identification. Three models have been chosen and their
ability to replicate the measured impedances is evaluated. On the one hand, the
common Rayleigh model is considered as a reference. On the other hand, a Zener
model and a model using complex constants are extended to model the transversely
isotropic material. As the Rayleigh model is only valid for a limited frequency
range, it fails to model the broadband behaviour of the material. The model using
complex constants leads to the best fit over a wide frequency range while at the
same time only adding three additional parameters for modelling damping. Thus,
damping can be assumed approximately frequency-independent in piezoceramics.

text: Curvature scale-space (CSS) analysis is an important technique for contour-based
object recognition in digital images. To compute the CSS for a given contour,
it is systematically convolved (smoothed) with Gaussians with increasing standard
deviation. The convolutions are computationally expensive, especially for large
and high resolution contours, but can be approximated using box filtering (also
known as mean and average filtering). Together with running sums, the convolutions
can be accelerated by 2–3 magnitudes without significant loss of precision. Nonetheless,
box filtering has not been systematically investigated in connection with CSS
computation. In this work, we present a theoretical and experimental analysis
of different box-filtering techniques in this context and conclude which is the
most efficient implementation. Based on this, the CSS of a contour can be computed
in real time with high precision.

text: As a complementary technology to existing Radio Frequency (RF)-based solutions
such as Cellular V2X (C-V2X) and Dedicated Short Range Communication (DSRC), Vehicular
VLC (V-VLC) is gaining more attention in the research community as well as in
the industry. This paper introduces a complete IEEE 802.11 compliant V-VLC system.
The system relies on Universal Software Radio Peripheral (USRP) software defined
radios programmed using the GNU Radio framework, a typical car headlight plus
a custom driver electronics for the high-power car LEDs (sender), and a photodiode
(receiver). Building upon our earlier work, we, for the first time, experimentally
explore the communication performance in outdoor scenarios, even in broad daylight,
and show that rather simple optical modifications help to reduce the ambient noise
to enable long distance visible light communication. Our system also supports
Orthogonal Frequency-Division Multiplexing (OFDM) with a variety of Modulation
and Coding Schemes (MCS) up to 64-QAM and is fully compliant with IEEE 802.11.
We performed an extensive series of experiments to explore the performance of
our system, even using higher order MCS in daylight. Our results demonstrated
a high reliability for distances up to 75m with the presented system, regardless
of the time of the day.

text: We present a guaranteed quality mesh generation algorithm for the
curvilinear triangulation of planar domains with piecewise polynomial boundary.
The resulting mesh consists of higher-order triangular elements which are not
only regular (i.e., with injective geometric map) but respect strict bounds on
quality measures like scaled Jacobian and MIPS distortion. This also implies that
the curved triangles' inner angles are bounded from above and below. These are
key quality criteria, for instance, in the field of finite element analysis. The
domain boundary is reproduced exactly, without geometric approximation error.
The central idea is to transform the curvilinear meshing problem into a linear
meshing problem via a carefully constructed transformation of bounded distortion,
enabling us to leverage key results on guaranteed-quality straight-edge triangulation.
The transformation is based on a simple yet general construction and observations
about convergence properties of curves under subdivision. Our algorithm can handle
arbitrary polynomial order, arbitrarily sharp corners, feature and interface curves,
and can be executed using rational arithmetic for strict reliability.

text: We describe an efficient algorithm to compute a discrete metric with
prescribed Gaussian curvature at all interior vertices and prescribed geodesic
curvature along the boundary of a mesh. The metric is (discretely) conformally
equivalent to the input metric. Its construction is based on theory developed
in [Gu et al. 2018b] and [Springborn 2020], relying on results on hyperbolic ideal
Delaunay triangulations. Generality is achieved by considering the surface's intrinsic
triangulation as a degree of freedom, and particular attention is paid to the
proper treatment of surface boundaries. While via a double cover approach the
case with boundary can be reduced to the case without boundary quite naturally,
the implied symmetry of the setting causes additional challenges related to stable
Delaunay-critical configurations that we address explicitly. We furthermore explore
the numerical limits of the approach and derive continuous maps from the discrete
metrics.

text: AbstractA homeomorphism between two surfaces
not only defines a (continuous and bijective) geometric correspondence of points
but also (by implication) an identification of topological features, i.e. handles
and tunnels, and how the map twists around them. However, in practice, surface
maps are often encoded via sparse correspondences or fuzzy representations that
merely approximate a homeomorphism and are therefore inherently ambiguous about
map topology. In this work, we show a way to infer topological information from
an imperfect input map between two shapes. In particular, we compute a homology
map, a linear map that transports homology classes of cycles from one surface
to the other, subject to a global consistency constraint. Our inference robustly
handles imperfect (e.g., partial, sparse, fuzzy, noisy, outlier‐ridden, non‐injective)
input maps and is guaranteed to produce homology maps that are compatible with
true homeomorphisms between the input shapes. Homology maps inferred by our method
can be directly used to transfer homological information between shapes, or serve
as foundation for the construction of a proper homeomorphism guided by the input
map, e.g., via compatible surface decomposition.
