Characteristic and necessary minutiae in fingerprints
(2021-10-22)Fingerprints feature a ridge line pattern inducing an undirected orientation field (OF) which usually features some singularities. Ridges vary in width, inducing a moderately varying ridge frequency (RF). In fingerprint ... -
Characteristic classes of vector bundles with extra structure
(2007-02-05)This work is about properties of characteristic cohomology classes which occur when a special structure on vector bundles is given. I have focused on two different types of these structures, treated in two independent parts. ... -
Characterization and construction of max-stable processes
(2013-08-30)Max-stable processes provide a natural framework to model spatial extremal scenarios. Appropriate summary statistics include the extremal coefficients and the (upper) tail dependence coefficients. In this thesis, the full ... -
Characters on infinite groups and rigidity
(2018-05-02)We show that for a strong extension of discrete measured groupoids $1\to\mathcal{S}\to\mathcal{G}\to\mathcal{Q}\to 1$ with $L\mathcal{G}$ a finite factor, $\mathcal{Q}$ has poperty (T) if and only if the inclusion of ... -
Charakterisierung eines Gebiets durch Spektraldaten eines Dirichletproblems zur Stokesgleichnung
(2004-02-17)We consider an inverse boundary value problem associated with the Stokes equation (in two and in three dimensions) and Dirichlet boundary condition.This problem requires the reconstruction of the ... -
Classical Conjectures in Iwasawa Theory for the split prime Z_p-extension and the cyclotomic Z_p-extension
(2021-04-15)This thesis constist of three parts. The first one considers the so called split prime Z_p extension over an imaginary quadratic field in which the rational prime p splits. In this setup we discuss the mu=0 conjecture as ... -
Classifiers for Discrimination of Significant Protein Residues and Protein-Protein Interaction Using Concepts of Information Theory and Machine Learning
(2012-01-18)The field of protein-analysis is a major research area for bioinformatics. Especially the field of predicting important sites in proteins is in the focus of research to reduce the cost and ... -
Classifying spaces for quasi-topological groups
(2025-10-24)This thesis provides a quick introduction into quasi-topological spaces, first introduced by Spanier. It then constructs notions of numerable principal G-bundles in the quasi-topological case and constructs a quasi-topological ... -
Coarse Cohomology with twisted Coefficients
(2019-04-18)This thesis studies sheaf cohomology on coarse spaces. -
Coarse Geometry for Noncommutative Spaces
(2016-11-23)We develop an analogoue of coarse geometry for noncommutative spaces in terms of unitizations of the given C* -algebra. Examples for our theory come from Rieffel deformation of compactifications under strongly continuous ... -
Composition theorems for paired Lagrangian distributions
(2012-04-12)The aim of this research is to determine whether the composition of paired Lagrangian distributions belongs to well-known classes such as marked Lagrangian, isotropic Lagrangian, paired Lagrangian or generalized ... -
Compressed Sensing and ΣΔ-Quantization
(2019-02-11)The main issue of my thesis is to bound the error while recovering signals from their compressed and quantized form. Especially my central contribution is that, together with my co-authors, we provide the first analysis ... -
Compression of visual data into symbol-like descriptors in terms of a cognitive real-time vision system
(2012-10-16)Humans have main senses: sight, hearing, touch, smell, and taste. Most of them combine several aspects. For example vision addresses at least three perceptual modalities: motion, color, and luminance. Extraction of these ... -
Computation with finitely L-presented groups
(2012-06-20)We develop algorithms for certain infinitely presented groups, the so-called finitely L-presented groups. For this purpose, we generalize the well-known algorithms for finitely presented groups to finite L-presentations. ... -
Computational Complexity Meets Statistical Efficiency: From Change Point Estimation to Monotonicity Testing
(2025-04-04)In the Information Age, statistical efficiency and computational tractability have become equally important. In this dissertation, we propose two novel statistical procedures: the Fast and Optimal Monotonicity Test (FOMT) ... -
Computational methods for random tomography with applications to cryo-EM data
(2022-08-01)Over the last decade, Cryo Electron Microscopy (cryo-EM) has emerged as a powerful and reliable technique to determine the three-dimensional (3D) structure of large macro-molecular assemblies at near atomic resolution. ... -
Computer Vision for Automated Robotic Device Disassembly: Object Detection, Pose Estimation, and Action Prediction
(2024-11-12)The growth in population and technology has led to an increased demand for electronic products, resulting in a higher volume of end-of-life devices. While recycling these products is critical for reducing environmental ... -
Concepts of Robustness for Uncertain Multi-Objective Optimization
(2014-04-30)In this thesis, several concepts of handling uncertainties in the formulation of mathematical optimization problems are presented. Some of these concepts are extensions of classical concepts of robustness for single objective ... -
Concordances in Positive Scalar Curvature and Index Theory
(2023-02-24)We apply the strategy to study of diffeomorphisms via block diffeomorphisms to the world of positive scalar curvature (psc) metrics. For each closed psc manifold, we construct the cubical set of all psc block metrics, the ... -
Conditional Privacy-Preserving Authentication Protocols for Vehicular Ad Hoc Networks
(2019-06-12)The Conditional Privacy-Preserving Authentication (CPPA) protocol has applications in the construction of secure Vehicular Ad hoc Networks (VANETs) due to its capability to achieve both privacy preservation and authentication ...
