Fabrication of Fresnel Zone Plates for Soft X-Ray and EUV Microscopy by Ion Beam Lithography
Overbuschmann, Johannes (2014-12-05)Fresnel zone plates are used as lenses for microscopes in the extreme ultraviolet (EUV) and the soft X-ray (SXR) parts of the electromagnetic spectrum. This thesis describes a novel approach for the fabrication of these ... -
Facies and sequence architecture of mixed carbonate-siliciclastic depositional systems during transforming sag to foreland basin geometries - “Sundance Basin”, Middle and Late Jurassic, western United States
Büscher, Olaf (2004)During the Middle Jurassic, the symmetric intracratonic “Sundance Basin” in the western portion of the North American continent was overridden by the approaching tectono-orogenic front of an early Cordilleran orogeny and ... -
Facility Location and Clock Tree Synthesis
Maßberg, Jens Uwe (2010-04-13)The construction of clock trees and repeater trees are major challenges in chip design. Such trees distribute an electrical clock signal from a source to a set of sinks on a chip. On recent designs there can be millions ... -
Factorability, Discrete Morse Theory and a Reformulation of K(π, 1)-conjecture
Ozornova, Viktoriya (2013-02-20)The first aim of this thesis is to study factorable groups and monoids. We give a new family of examples for factorability structures, provided by Garside theory, in particular, we provide a factorability structure on braid ... -
Factorable Groups and their Homology
Visy, Balázs (2011-07-04)In this thesis we introduce the class of factorable groups. These are normed groups together with a norm preserving decemposition (or factorization) of each group element into two factors. <br /> Already the norm alone ... -
Factorable Monoids: Resolutions and Homology via Discrete Morse Theory
Heß, Alexander (2012-07-26)We study groups and monoids that are equipped with an extra structure called factorability.<br /> A factorable group can be thought of as a group G together with the choice of a generating set S and a particularly well-behaved ... -
Factorization of holomorphic eta quotients
Bhattacharya, Soumya (2014-12-12)We conjecture the occurrence of a certain type of factor of a holomorphic eta quotient whenever it is reducible and we prove this conjecture for all prime power levels. In particular, this also implies that rescaling and ... -
Familien-basierte Assoziationsanalyse mit Haplotypen: eine Simulationsstudie zum Vergleich statistischer Methoden
Mende, Meinhard (2009-09-09)Bei der Aufklärung der Ursachen komplexer Krankheiten helfen Assoziationsverfahren genetische Varianten zu finden, die das Krankheitsrisiko beeinflussen. Familien-basierte Methoden haben dabei den Vorteil, nicht anfällig ... -
Far-infrared-to-centimeter-wave spectroscopicobservations of Planck-selected starburst galaxies
Harrington, Kevin Corneilus (2021-03-15)Star-formation processes in the early Universe have had a dramatic influence on the further development of galaxies. The peak era for stellar production occurred in early cosmic times, and most of the stars that could have ... -
The Farrell-Jones conjecture for some general linear groups
Rüping, Henrik (2013-07-10)In this thesis I prove the K- and L-theoretic Farrell-Jones conjecture with coefficients in any additive category for the general linear groups of F(x) for a finite field F. I also show that the general linear groups over ... -
Faserbasierte Simulation von Humanhaar
Sobottka, Gerrit (2009-04-09)Gegenstand dieser Arbeit ist die Entwicklung eines faserbasierten parametrischen Haarmodells zur numerischen Simulation komplexer Faseranordnungen. Parametrisch bedeutet, dass neben Geometrieinformationen grundlegende, die ... -
Faserhodoskope im COMPASS-Experiment zum Nachweis von Teilchenspuren innerhalb des Primärstrahls
Nähle, Ole Jens (2002)Für das COMPASS-Experiment am CERN wurden Hodoskope aus szintillierenden Fasern entwickelt, getestet und in das Experiment integriert. Die Spurrekonstruktion im oder in unmittelbarer Nähe des Primärstrahls stellt hohe ... -
Fast detection of protein-protein interactions with an automated FRET-based system on the flow cytometer
von Kolontaj, Kerstin (2018-03-12)Although protein-protein interactions play a major role in almost all biological functions, those interactions cannot easily be analysed, especially not on single cell level and with regard to dynamic changes in protein ... -
Fast diffusion MRI based on sparse acquisition and reconstruction for long-term population imaging
Koch, Alexandra (2019-11-21)Diffusion weighted magnetic resonance imaging (dMRI) is a unique MRI modality to probe the diffusive molecular transport in biological tissue. Due to its noninvasiveness and its ability to investigate the living human brain ... -
Fast non-destructive internal state detection of neutral atoms in optical potentials
Martínez Dorantes, Miguel (2016-11-29)Neutral atoms trapped in optical lattices are promising candidates for quantum information processing and quantum simulation. Over the last decades, elegant tools for the manipulation of the internal and external states ... -
Fast Optimised Wavelet Methods for Control Problems Constrained by Elliptic PDEs
Burstedde, Carsten (2005)In this thesis, a wavelet method for the numerical solution of an optimal control problem constrained by a linear elliptic partial differential equation is developed. The particular challenge here lies in considering and ... -
Fast Repeater Tree Construction
Bartoschek, Christoph (2014-09-18)Repeaters are used during physical design of chips to improve the electrical and timing properties of interconnections. They are added along Steiner trees that connect root gates to sinks, creating repeater trees. Their ... -
Fast Resource Sharing in VLSI Routing
Müller, Dirk (2010-02-04)Routing is the last major step in chip design. It naturally splits into <i>global</i> and <i>detailed routing</i>: In global routing, an approximate layout of electrical connections is computed, subject to constraints on ... -
Fast Time-optimal Trajectory Generation for Jerk-controlled Systems
Beul, Marius (2022-02-14)Trajectory generation plays a central role in the quest to enhance the capabilities and performance of all kinds of robots.<br /> Current state-of-the-art trajectory generation methods are either not time-optimal, need ... -
Fast, Accurate and Steerable Segmentation of Drusen in Optical Coherence Tomography
Gorgi Zadeh, Shekoufeh (2020-10-05)Age-related macular degeneration (AMD) is known to be the leading cause for blindness in developed countries. One of the early appearing biomarkers of AMD are drusen that develop between the retinal pigment epithelium (RPE) ...
