Harmonic analysis on 2-step stratified Lie groups without the Moore-Wolf condition
(2022-04-07)In this thesis we investigate harmonic analysis on a particular class of sub-Riemannian manifold, namely the 2-step stratified Lie groups $\mathbb{G}$, as well as its applications in partial differential equations. This ... -
Heterogeneous Multiscale Change-Point Inference and its Application to Ion Channel Recordings
(2018-02-09)Ion channel recordings by the patch clamp technique are a major tool to quantify the electrophysiological dynamics of ion channels in the cell membrane, which is for instance important in medicine for the development of ... -
Hierarchically linked extended features for fingerprint processing
(2009-03-23)This thesis discusses a novel approach for fingerprint feature extraction. A new fingerprint structure has been proposed as a basis for the extraction of extended features. These new features ... -
High-order Unfitted Discretizations for Partial Differential Equations Coupled with Geometric Flow
(2023-02-17)We consider a moving free boundary problem where a diffusion equation posed on an evolving domain bounded by a smooth surface is coupled with a mean curvature flow of the bounding surface. The evolution velocity of the ... -
High-Performance Persistent Identification for Research Data Management
(2018-09-17)Durable identification and access to datasets, especially to research datasets, become increasingly important. This is mainly driven by the explosive dataset growth in the current age. Although the Internet was originally ... -
Higher Currents for the sine-Gordon Model in perturbative Algebraic Quantum Field Theory
(2024-09-19)The main results of this thesis are the establishment of the super-renormalizability by power counting and of the summability of an infinite number of (classically conserved) higher currents for the sine-Gordon model in ... -
Higher Groupoid Actions, Bibundles, and Differentiation
(2014-08-13)In this thesis, we employ simplicial methods to study actions, principal bundles and bibundles of higher groupoids. Roughly, we use Kan fibrations to model actions of higher groupoids; we use pairs of a Kan fibration ... -
Higher Lefschetz invariants for foliated manifolds
(2012-05-22)Let $(M, F)$ be a compact foliated manifold. Suppose that a compact Lie group $Γ$ acts on $(M, F)$ by diffeomorphisms of Mthat map each leaf onto itself. We call such a structure a foliated $Γ$ -manifold and denote it ... -
Identification of model and grid parameters for incompressible turbulent flows
(2007-10-24)The present thesis studies the behavior of turbulence models for incompressible flows based on the DLR-THETA-code and calibrates relevant model and grid parameters arising in the numerical ... -
Identification of Online Users' Social Status via Mining User-Generated Data
(2019-09-11)With the burst of available online user-generated data, identifying online users’ social status via mining user-generated data can play a significant role in many commercial applications, research and policy-making in many ... -
Identifying dependencies among delays
(2008-02-29)The treatment of disturbances in case of capacity restrictions in the Delay management problem has been theoretically and numerically examined. A new formulation of these secondary conditions for the macromodel of the ... -
Imbalance Learning and Its Application on Medical Datasets
(2021-05-28)To gain more valuable information from the increasing large amount of data, data mining has been a hot topic that attracts growing attention in this two decades. One of the challenges in data mining is imbalance learning, ... -
Improvement of the jpHMM approach to recombination detection in viral genomes and its application to HIV and HBV
(2011-08-08)Accurate virus genotyping and the detection of recombinant strains are of crucial importance for understanding viral evolution as well as the design of potential vaccines and treatment ... -
Improving IoT device transparency by means of privacy labels
(2022-05-20)The Internet of Things (IoT) is an umbrella-term that applies to sensors, actuators and other devices that can interact with each other, or with other systems over the Internet. This technology has the potential to improve ... -
Improving the analysis of aeroacoustic measurements through machine learning
(2023-11-20)This thesis focuses on improving the analysis of aeroacoustic imaging methods using automated data processing and machine learning. Imaging methods result in beamforming maps that are challenging to explore manually since ... -
Increasing the robustness of active upper limb prostheses
(2017-02-02)This thesis is based on my work done at the Institute for Neurorehabilitation Systems at the University Medical Center Goettingen. My work has been partially founded by German Ministry for Education and Research (BMBF) via ... -
Index theory and groupoids for filtered manifolds
(2020-12-21)In this thesis, we propose to use generalized fixed point algebras as an approach to the pseudodifferential calculus on filtered manifolds. A filtered manifold is a manifold \(M\) with a filtration of its tangent ... -
Index Theory and Positive Scalar Curvature
(2020-07-24)The aim of this dissertation is to use relative higher index theory to study questions of existence and classification of positive scalar curvature metrics on manifolds with boundary. First we prove a theorem relating ... -
Index Theory and Positive Scalar Curvature
(2012-06-22)Obstructions to the existence of positive scalar curvature metrics are considered. This thesis has two fairly independent parts. The first part of this thesis proves that the Roe (or coarse) index of the Dirac-Rosenberg ... -
Individuelle Curricula von Lehrkräften in der Algebra
(2016-08-04)The framework of the Research Project Subjective Theories (RPST) is used to reconstruct secondary teachers’ belief systems on their classroom practices concerning algebra. It aims at describing the individual knowledge and ...
