Detection and Simulation of Dangerous Human Crowd Behavior
(2013-01-09)
Tragically, gatherings of large human crowds quite often end in crowd disasters such as the recent catastrophe at the Loveparade 2010. In the past, research on pedestrian and crowd dynamics focused on simulation of pedestrian ...
A Digital Library Framework for Heterogeneous Music Collections - from Document Acquisition to Cross-Modal Interaction
(2013-08-27)
In the digital age, increasing amounts of digitized music materials result in the need for automated management processes. Especially for libraries and other content-providing organizations holding large and due to ongoing ...
On Approximability of Bounded Degree Instances of Selected Optimization Problems
(2013-08-07)
In order to cope with the approximation hardness of an underlying optimization problem, it is advantageous to consider specific families of instances with properties that can be exploited to obtain efficient approximation ...
Music Synchronization, Audio Matching, Pattern Detection, and User Interfaces for a Digital Music Library System
(2013-07-11)
Over the last two decades, growing efforts to digitize our cultural heritage could be observed. Most of these digitization initiatives pursuit either one or both of the following goals: to conserve the documents - especially ...
Microarrayanalyse gynäkologischer Tumorentitäten
(2013-07-10)
Softwareentwicklung Die Analyse von Genexpressionsprofilen fällt nicht länger exklusiv in den Aufgabenbereich von Bioinformatik Experten. Jedoch gestaltet sich der Erhalt von statistisch signifikanten Resultaten schwierig ......
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 ...
