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 ... -
Confidence bands for structural relationship models
(2007-01-29)The goal of the thesis is to construct the simultaneous confidence bands for structural relationship models introduced by Freitag (2000), Freitag and Munk (2005). Consider the two-sample ... -
Conformal Properties of Generalized Dirac Operator
(2013-07-24)In this thesis we study the non-linear Dirac operator in dimension four and the associated generalization of the Seiberg-Witten equations in dimension four. The central object of this generalization is a hyperK ahler ... -
Constructing Temporal Transcriptional Regulatory Cascades in the Context of Development and Cell Differentiation
(2020-07-14)Cell differentiation is a complex process orchestrated by sets of regulators appearing at precise temporal points, resulting in regulatory cascades that affect the expression of broader sets of genes, ending up in the ... -
Consumer Behavior Analysis and Repeat Buyer Prediction for E-commerce
(2019-12-16)The proliferation of mobile devices especially smart phones brings remarkable opportunities for both industry and academia. In particular, the massive data generated from users' usage logs provide the possibilities for ... -
Content Agnostic Malware Detection in Networks
(2012-07-04)Bots are the root cause of many security problems on the Internet - they send spam, steal information from infected machines, and perform distributed denial of service attacks. Given their security impact, it is not ... -
Context- and Physiology-aware Machine Learning for Upper-Limb Myocontrol
(2018-05-16)The world around us is shaped in such a way that our hands are necessary to accomplish most activities of daily living. It is therefore undeniable that the loss of the upper limb, partial or total, represents a severe ... -
Continuous Wavelet Transformation on Homogeneous Spaces
(2021-03-29)The classical Continuous Wavelet Transformation (cCWT) is an important and well-studied tool in signal processing and data analysis. Because of its deep connection to representation theory, it has come into focus of pure ... -
Contributions to the Theory of Statistical Optimal Transport
(2022-07-01)The application of optimal transport based methodologies for statistical purposes has experienced a surge of interest and activity in recent years. This doctoral thesis collects the work of four research articles on the ... -
Controlling Data Streams of IoT Devices in Smart Homes from a User Perspective
(2024-04-16)Increasingly, humans are surrounded by intelligent devices, such as smart devices, in the Internet of Things (IoT) context. These smart devices are used in various environments, such as smart environments as well as homes. ... -
Convergence of the Genealogy of the Spatial Cannings Model
(2016-11-16)In this thesis we consider the genealogy of a spatial Cannings model. This is a population model in which individuals are distributed over a countable set of sites G. The reproduction of individuals at each site is ... -
Convergence rates for variational regularization of inverse problems in exponential families
(2020-07-16)We consider statistical inverse problems with statistical noise. By using regularization methods one can approximate the true solution of the inverse problem by a regularized solution. The previous investigation of convergence ... -
Convergence rates for variational regularization of statistical inverse problems
(2020-05-13)We consider inverse problems with statistical (noisy) data. By applying regularization methods one can approximate the true solution of the inverse problem by a regularized solution. In this thesis we show convergence rates ... -
Convergence Rates in Dynamic Network Models
(2018-02-23)The stochastic network model by Britton and Lindholm (Journal of Statistical Physics 3, 2010) describes a class of reasonably realistic dynamics for a complex system with an underlying network structure. In a closed social ... -
Cooperative Internet Access in Resource Constrained Environments
(2011-04-07)Access to the Internet has become available at virtually any place in developed and developing countries, either by fixed-line or wireless access. The Internet users are used to check ... -
Critical exponents for semilinear Tricomi-type equations
(2016-11-24)In this thesis, we consider the semilinear Tricomi-type equations. In particular, we work on the global Cauchy problem for the semilinear Tricomi-type equation with suitable initial data. The main objective of this thesis ... -
Cryptanalysis of the Fuzzy Vault for Fingerprints: Vulnerabilities and Countermeasures
(2013-07-08)The fuzzy fingerprint vault is a popular approach to protect a fingerprint's minutiae as a building block of a security application. In this thesis simulations of several attack scenarios are conducted against implementations ... -
CUDA-based Scientific Computing
(2013-02-12)The first goal of this thesis is the design of SciPAL (Scientific and Parallel Algorithms Library), a C++-based and operating-system-independent library. The core of SciPAL is a domain-specific embedded language for dense ... -
Cyclotomic Norm Diophantine Equations
(2023-10-25)In this thesis, I consider two Diophantine norm equations. For the equation of the Nagell-Ljunggren equation $\frac{x^p-1}{x-1} = p^e y^q$ with distinct odd prime exponents $p, q$, I show that, for $p > 3$, it has no ...
