6D-Posenbestimmung und 3D-Objektrekonstruktion mittels der 2D-Form von Bildsegmenten
(2022-04-14)This thesis presents a template-based method for the calculation of the 6D pose with a following 3D reconstruction of objects in a scene. In applications for computer-aided manipulations, e.g., in the field of robotics, ... -
A Bayesian approach to initial model inference in cryo-electron microscopy
(2016-03-18)Single-particle cryo-electron microscopy (cryo-EM) is widely used to study the structure of macromolecular assemblies. Tens of thousands of noisy two-dimensional images of the macromolecular assembly viewed from different ... -
A Biased Urn Model for Taxonomic Identification
(2009-03-24)We consider a stochastic model for the problem of taxonomic identification in bacterial genomes, motivated by the detection of horizontal gene transfer between non-closely related species. ... -
A Bio-Inspired Autonomous Authentication Mechanism in Mobile Ad Hoc Networks
(2012-12-21)A Mobile Ad hoc NETwork (MANET) is an infrastructureless self-configuring network in that nodes themselves create and manage the network in a self-organized manner. Nodes can communicate only with their neighbors that ... -
A Bioinformatics Pipeline for Identifying Dysregulated Pathways in Cancer from Comparative RNA-Seq Transcriptome Analysis
(2022-04-07)Cancer is characterized as a multifactorial disease which undergoes genetic and epige- netic changes during invasive tumor growth. Thus, numerous tumor samples have been profiled using high-throughput sequencing technologies ... -
A Central Limit Theorem for Functions on Weighted Sparse Inhomogeneous Random Graphs
(2023-07-13)We prove a central limit theorem for a certain class of functions on weighted sparse inhomogeneous random graphs. The proof uses a perturbative form of Stein's method and relies on a careful analysis of the local structure ... -
A Chimera simulation method and Detached Eddy Simulation for vortex-airfoil interactions
(2011-01-25)The present thesis introduces, verifies and validates a numerical simulation method based on an overset grid (or Chimera) technique that allows to simulate the generation and transport ... -
A classification of localizing subcategories by relative homological algebra
(2015-12-17)In this thesis, we use the tools of relative homological algebra in triangulated categories to define a sensible notion of support for objects in the bootstrap class of a Kasparov category of C*-algebras over a finite ... -
A colimit construction for groupoids
(2016-08-03)We consider Ore monoid actions in a certain bicategory of étale groupoids Gr_prop. Examples of such actions include self-similar groups, higher rank graphs and actions of Ore monoids on spaces by topological correspondences. ... -
A Comparison of Models and Methods for Spatial Interpolation in Statistics and Numerical Analysis
(2010-06-18)Interpolation of spatial data is a very general mathematical problem with many applications, such as surface reconstruction, the numerical solution of partial differential equations, learning ... -
A Content-Oriented Architecture for Publish/Subscribe Systems
(2015-04-01)With the user behavior of Internet shifting towards data dissemination and retrieval, Information Centric Networking (ICN) is proposed to suit these demands. ICN treats content as the first-class entity, with nodes exchanging ... -
A discrete geometric view on shear-deformable shell models
(2012-08-15)This thesis presents the construction of a geometrically nonlinear shear-deformable (Cosserat type) shell model by methods from discrete differential geometry (DDG). The model aims at applications in real-time simulations ... -
A Fine-Grain Scalable and Channel-Adaptive Hybrid Speech Coding Scheme for Voice over Wireless IP
(2006-12-13)Wireless LANs (WLANs) are being more and more widely deployed at present. They are a key element in dynamic business environments where permanent access to network resources is vital. They ... -
A Framework for managing Quality of Service in Cloud Computing through Service Level Agreements
(2017-01-16)Until today, Cloud providers only offer a limited set of non-negotiable service levels to their customers. Most often these service levels are expressed as guarantees for availability together with the offer to have ... -
A Framework for Property-preserving Encryption in Wide Column Store Databases
(2017-08-15)While traditional database software usually relies on the relational SQL model, a lot of alternative approaches, commonly referred to as NoSQL (short for \Not only SQL") databases, occurred within the last years to meet ... -
A Grid-Adaptive Algebraic Hybrid RANS/LES Method
(2016-04-04)The present thesis considers the compressible Navier-Stokes equations to simulate the flow of air about basic and complex test cases. As numerical solution method the unstructured finite-volume solver DLR-TAU is used. The ... -
A Hybrid Method for Inverse Obstacle Scattering Problems
(2007-05-30)We are interested in solving the time-harmonic inverse acoustic scattering problem. In this work, we present the state of the art of a new iterative method to numerically solve this problem. ... -
A knowledge base for generating patient-specific pathways for individualized treatment decisions in clinical applications
(2022-09-29)The vast amount of published data on molecular interactions makes it increasingly challenging for researchers and practitioners to find and extract the most relevant information to target the underlying diseases. Network ... -
A level set approach to integer nonlinear optimization
(2013-11-19)Integer nonlinear optimization programs form a class of very hard problems. Often it is much easier to solve the continuous relaxation. Therefore we are interested in this thesis in identifying special cases of integer ... -
