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 global and detailed routing: 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.
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) ... -
Faster Circuits for And-Or Paths and Binary Addition
Hermann, Anna (2020-07-24)We consider the problem of constructing fast circuits both for binary addition and And-Or paths. And-Or paths are Boolean functions of the form t0 ∧ ( t1 ∨ ( t2 ... -
The fate of a recessive allele in a Mendelian diploid model
Ströfer, Rebecca Sarah (2017-08-23)The omnipresence of sexual reproduction in a highly competitive world is a fascinating phenomenon. Its evolution and maintenance is up to now not completely understood since it is known that sexual reproduction require ... -
Fault Roughness and Fault Complexity: Field Study, Multi-Scale Analysis and Numerical Fault Model
Navarro, Martin (2002)We study the roughness of normal faults in lignite and its relevance to the complex process of faulting by means of field observations and a numerical model for wear at rough fault surfaces. Roughness data is collected at ... -
Faunal Provinces and Patterns of Diversity in Late Cretaceous (Santonian-Maastrichtian) Larger Foraminifera
Goldbeck, Elke J. (2008)A detailed biogeographical analysis of the global distribution of 25 different genera of larger symbiont-bearing foraminifera from the Late Cretaceous reveals that they exhibit distinct patterns. On a generic level, the ... -
Fälschungen pflanzlicher Arzneimittel, Lebensmittel und Kosmetika: Regulierung von Arzneimitteln und Lebensmitteln im Hinblick auf die Fälschungssicherheit von pflanzlichen Produkten
Müller, Iris Annette (2015-11-18)Pflanzliche Arzneimittel, Medizinprodukte und Lebensmittel oder Kosmetika werden von immer mehr gesundheits- und umweltbewussten Patienten verwendet. Auf der anderen Seite nimmt die Zahl von Arzneimittelfälschungen und ... -
Feasibility and Efficacy of a Collaborative Medication Management for Elderly, Multimorbid Patients
Rose, Olaf (2017-08-29)Medication Review and Medication Management are new pharmaceutical care services with a strong potential to contribute to patients’ health care outcomes. The aim of this work was to evaluate an interprofessional, collaborative ... -
Federated Query Processing over Heterogeneous Data Sources in a Semantic Data Lake
Endris, Kemele M. (2020-05-05)Data provides the basis for emerging scientific and interdisciplinary data-centric applications with the potential of improving the quality of life for citizens. Big Data plays an important role in promoting both manufacturing ... -
Femtosekunden-Infrarot-Spektroskopie von dreiatomigen Pseudohalogenid-Ionen sowie organischen und anorganischen Pseudohalogenid-Verbindungen
Czurlok, Denis (2016-01-20)Die charakteristische, starke Resonanz dreiatomiger Pseudohalogenide im Frequenzbereich von 2000 cm-1 wurde als spektrale Sonde verwendet, um ultraschnelle Vorgänge in kondensierter Materie aufzuklären. Dazu ... -
Fermat Reals: Nilpotent Infinitesimals and Infinite Dimensional Spaces
Giordano, Paolo (2010-01-20)The main aim of the present work is to start a new theory of actual infinitesimals, called theory of Fermat reals. After the work of A. Robinson on nonstandard analysis (NSA), several theories of infinitesimals have been ... -
Fernerkundungsgestützte Modellierung kleinräumiger Biodiversität am Beispiel des Turtmanntals in der Schweiz
Kleinod, Konstanze (2008)Hochgebirge sind Regionen mit extrem hoher Biodiversität. Sie erschließen die dritte Dimension, das heißt sie enthalten eine vertikale Klimazonierung auf sehr kurzer Distanz, was zu einer Komprimierung der Vegetationszonen ... -
Ferredoxin-dependent electron transport during methanogenesis from acetate
Welte, Cornelia (2011-09-12)Methanogenic archaea are one of the key groups in global carbon turnover. They metabolize the conversion of the end products of the anaerobic food chain to methane. Of particular importance is the methanogenesis with acetate ... -
Ferromagnetic Semiconductor-Metal Transition in Europium Monoxide
Arnold, Michael (2007)We present a microscopical model to describe the simultaneous parato- ferromagnetic and semiconductor-to-metal transition in electrondoped EuO. The physical properties of the model are systematically studied, whereas the ... -
