Social-Based Data Routing Strategies in Delay Tolerant Networks
(2014-04-03)Delay Tolerant networks (DTNs) are intermittently connected mobile networks in which the end-to-end paths do not exist. Data delivery in such networks relies upon the contacts that use "store-carry-and-forward" paradigm ... -
Solution approaches for facility layout problems
(2021-01-29)The chief executive officers of real-world factories aim to implement a cost efficient production. The layout of the operating equipment is one of the main influencing factors and this leads to facility layout problems. ... -
Solution Methods for Multi-Objective Robust Combinatorial Optimization
(2018-05-02)This thesis addresses combinatorial optimization problems with several objectives containing uncertain parameters. A variety of robustness concepts for multi-objective optimization problems have been developed during the ... -
Some Aspects on Coarse Homotopy Theory
(2010-01-08)The most important examples of coarse spaces arise from proper metrics on spaces or from metrisable compactifications. In both cases, the bounded subsets are precisely the relatively compact ones. On the other hand, one ... -
Some remarks on the central limit theorem for stationary Markov processes
(2004-05-19)The central limit theorem for additive functionals of stationary ergodic Markov processes is investigated via the method of martingale approximations. We give a necessary and sufficient ... -
Sparse Fast Trigonometric Transforms
(2019-07-22)Trigonometric transforms like the Fourier transform or the discrete cosine transform (DCT) are of immense importance in signal and image processing, physics, engineering, and data processing. The research of past decades ... -
Spatial Coherence Enhancing Reconstructions for High Angular Resolution Diffusion MRI
(2016-01-21)A main step in processing and analyzing data obtained from High Angular Resolution Diffusion MRI is the reconstruction of some measure of diffusion per spatial location and per direction in the volume under examination. ... -
Spatial Interpolation and Prediction of Gaussian and Max-Stable Processes
(2012-07-04)This thesis deals with different aspects of spatial interpolation and prediction of random fields. In the case of Gaussian random fields, best linear predictors and conditional distributions are well-known, provided that ... -
Spatio-temporal reasoning for semantic scene understanding and its application in recognition and prediction of manipulation actions in image sequences
(2020-04-21)Human activity understanding has attracted much attention in recent years, due to a key role in a wide range of applications and devices, such as human- computer interfaces, visual surveillance, video indexing, intelligent ... -
Stabilisierte Lagrange Finite-Elemente im Elektromagnetismus und in der inkompressiblen Magnetohydrodynamik
(2015-11-05)This thesis deals with the usage of nodal-based finite element methods in electromagnetism and incompressible magnetohydrodynamics. At first, we start to investigate the induction equation from Maxwell's equation. We give ... -
Stabilized Finite Element Methods for Coupled Incompressible Flow Problems
(2016-01-28)In this thesis, a finite element discretization of the incompressible Navier-Stokes equations for a non-isothermal and electrically conducting fluid in a possibly rotating frame of reference is considered. In particular, ... -
Stable Bases for Kernel Based Methods
(2013-03-18)Kernels K arise in many contexts, including approximation, surface reconstruction, numerical analysis of fluid-structure interactions, and geostatistics. In particular, the span of translates K(.,x) for scattered ... -
Statistical and Structural Aspects of Unbalanced Optimal Transport Barycenters
(2022-10-20)Optimal transport (OT) has seen a stellar rise in interest and relevance in the past two decades. More recently, severe limitation of OT have started to surface. Two key factors prevent it from becoming a standard tool in ... -
Statistical Inference for Propagation Processes on Complex Networks
(2014-07-29)Scientists of various research fields have discovered the advantages of network-centric analysis, which captures complex systems by networks and allows for their representation as a collection of nodes connected by links. ... -
Statistical Limit Laws for Graph Cuts and Efficient Surrogate Algorithms
(2024-12-05)Graph cuts are a powerful tool that has been used in many applications, from image segmentation and machine learning to network analysis and cluster identification, often in the form of a convex relaxation such as spectral ... -
