Exploiting Network Coding in Lossy Wireless Networks
(2009-06-08)Users increasingly depend on Wireless LANs (WLANs) for business and entertainment. It is well-known that wireless links are error-prone and require retransmissions to recover from errors ... -
Exploring Stickiness in CAT(κ) Spaces
(2024-10-10)The Fréchet mean is a natural generalization of the expectation to probability distributions on arbitrary metric spaces. In recent years, several seemingly related phenomena were observed for certain distributions on ... -
Extending the Programming Language XL to Combine Graph Structures with Ordinary Differential Equations
(2012-04-13)Natural sciences try to discover laws that allow to explain and predict observations. Often, models are created with the purpose to verify or falsify proposed theories, which are based on these laws and certain other ... -
Extension of the Rule-Based Programming Language XL by Concepts for Multi-Scaled Modelling and Level-of-Detail Visualization
(2015-04-28)Dissertation on the extension of the programming language XL by concepts of multi-scaled modelling. This dissertation includes work on definitions of graph models and grammar for multiscale modelling, particularly in the ... -
Extreme-Value Analysis of Self-Normalized Increments
(2007-06-20)We prove a distributional convergence version of Levy's theorem on the continuity modulus of the Brownian motion. The result is extended to totally skewed alpha-stable processes. -
Facility Location in the Phylogenetic Tree Space
(2019-03-25)Phylogenetics is a field of biology trying to describe the evolutionary history of a given set of populations or species. Evolutionary relationships are obtained through statistical models for phylogenetic inference. In ... -
Fast methods for metagenomic sequence search and annotation
(2022-06-16)The past two decades have seen the development of metagenomics, the study of genes and genomes of multiple organisms simultaneously. In contrast to traditional genomic techniques, which require isolating and growing ... -
Field and Shape Reconstruction in Fluid Dynamics
(2011-07-20)Inverse problems are concerned with the reconstruction of quantities from remote measurements. Inverse fluid flow problems are important for many applications, for example for determining ... -
Field reconstructions and range tests for acoustics and electromagnetics in homogeneous and layered media
(2008-06-02)In acoustic and electromagnetic scattering various methods for the reconstruction of the shape of an unknown object are examined. In particular, the multiwave range test is developed based ... -
Financial Models of Interaction Based on Marked Point Processes and Gaussian Fields
(2013-01-16)This thesis deals with interaction phenomena in marked point processes, with particular attention being paid to the extreme value theory framework and with application to high-frequency financial data. While ... -
Fingerprint Growth Prediction, Image Preprocessing and Multi-level Judgment Aggregation
(2011-01-06)Finger growth is studied in the first part of the thesis and a method for growth prediction is presented. The effectiveness of the method is validated in several tests. Fingerprint image ... -
Finite Alphabet Blind Separation
(2018-01-04)This thesis considers a particular blind source separation problem, where the sources are assumed to only take values in a known finite set, denoted as the alphabet. More precisely, one observes M linear mixtures of m ... -
Finite Element Methods with Local Projection Stabilization for Thermally Coupled Incompressible Flow
(2015-09-15)This thesis considers conforming finite element discretizations for the time-dependent Oberbeck-Boussinesq model with a pressure-correction projection scheme of second order in time. Discrete inf-sup stability of the ansatz ... -
Finite-element simulation of buoyancy-driven turbulent flows
(2003-08-25)Turbulent flows driven or significantly affected by buoyancy occur in a variety of problems including building ventilation, cooling of electrical equipment, and environmental science. The ... -
Eine Finite-Elemente-Methode für nicht-isotherme inkompressible Strömungsprobleme
(2011-10-31)In this thesis, various aspects of the implementation of a solver for turbulent non-isothermal incompressible flow problems are considered. This includes in particular a spatial discretization ... -
Firewall Traversal in Mobile IPv6 Networks
(2008-11-26)Middleboxes such as firewalls are an important aspect for a majority of IP networks today. Current IP networks are predominantly based on IPv4 technology, and hence various firewalls as ... -
Fixed Point Algorithms for Nonconvex Feasibility with Applications
(2014-07-31)Projection algorithms for solving (nonconvex) feasibility problems provide powerful and computationally efficient schemes for a wide variety of applications. Algorithms as Alternating Projections (AP) and Douglas-Rachford ... -
Foliated Positive Scalar Curvature
(2021-11-11)In this thesis we study different questions on scalar curvatures. The first part is devoted to obstructions against existence of a (Riemannian) metric with positive scalar curvature on a closed manifold. The second ... -
Fourier and Variational Based Approaches for Fingerprint Segmentation
(2015-05-22)Fingerprint recognition plays an important role in many commercial applications and is used by millions of people every day, e.g. for unlocking mobile phones. Fingerprint image segmentation is typically the first processing ... -
