Analysis and Manipulation of Repetitive Structures of Varying Shape
(2013-05-22)
Self-similarity and repetitions are ubiquitous in man-made and natural objects. Such structural regularities often relate to form, function, aesthetics, and design considerations. Discovering structural redundancies along ...
Image-Based Approaches to Hair Modeling
(2013-06-06)
Hair is a relevant characteristic of virtual characters, therefore the modeling of plausible facial hair and hairstyles is an essential step in the generation of computer generated (CG) avatars. However, the inherent ...
From Acoustic Mismatch Towards Blind Acoustic Model Selection in Automatic Speech Recognition
(2013-05-24)
Acoustic distortion and acoustic mismatch are two of the most critical aspects influencing automatic speech recognition. A speech signal recorded from a speaker in a certain acoustic environment compared to a signal from ...
Formation Navigation and Relative Localisation of Multi-Robot Systems
(2013-05-07)
When proceeding from single to multiple robots, cooperative action is one of the most relevant topics. The domain of robotic security systems contains typical applications for a multi-robot system (MRS). Possible scenarios ...
Algebraic Uncertainty Theory: A Unifying Perspective on Reasoning under Uncertainty
(2013-05-22)
The question of how to represent and process uncertainty is of fundamental importance to the scientific process, but also in everyday life. Currently there exist a lot of different calculi for managing uncertainty, each ...
Pedestrian Mobility Mining with Movement Patterns
(2013-12-11)
In street-based mobility mining, pedestrian volume estimation receives increasing attention, as it provides important applications such as billboard evaluation, attraction ranking and emergency support systems. In practice, ...
Free Theorems in Languages with Real-World Programming Features
(2013-11-07)
Free theorems, type-based assertions about functions, have become a prominent reasoning tool in functional programming languages. But their correct application requires a lot of care. Restrictions arise due to features ...
Approximability of Combinatorial Optimization Problems on Power Law Networks
(2013-10-30)
One of the central parts in the study of combinatorial optimization is to classify the NP-hard optimization problems in terms of their approximability. In this thesis we study the Minimum Vertex Cover (Min-VC) problem and ...
Dilation, Transport, Visibility and Fault-Tolerant Algorithms
(2014-07-09)
Connecting some points in the plane by a road network is equivalent to constructing a finite planar graph G whose vertex set contains a predefined set of vertices (i. e., the possible destinations in the road ...
Fast Repeater Tree Construction
(2014-09-18)
Repeaters are used during physical design of chips to improve the electrical and timing properties of interconnections. They are added along Steiner trees that connect root gates to sinks, creating repeater trees. Their ...
