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 ...
Transistor-Level Layout of Integrated Circuits
(2014-07-29)
In this dissertation, we present the toolchain BonnCell and its underlying algorithms. It has been developed in close cooperation with the IBM Corporation and automatically generates the geometry for functional groups of ...
Steuerung und Überwachung einer Zeitprojektionskammer mit GEM-Auslese
(2014-03-10)
Für ein tieferes Verständnis der starken Wechselwirkung und des Aufbaus der Nukleonen untersucht das CBELSA/TAPS-Experiment im Rahmen des Sonderforschungsbereichs SFB/TRR 16 "Elektromagnetische Anregung subnuklearer Systeme" ...
Automated Optimization Methods for Scientific Workflows in e-Science Infrastructures
(2014-04-22)
Scientific workflows have emerged as a key technology that assists scientists with the design, management, execution, sharing and reuse of in silico experiments. Workflow management systems simplify the management of ...
Shape Retrieval Methods for Architectural 3D Models
(2014-02-21)
This thesis introduces new methods for content-based retrieval of architecture-related 3D models. We thereby consider two different overall types of architectural 3D models. The first type consists of context objects that ...
Three-dimensional Laser-based Classification in Outdoor Environments
(2014-02-18)
Robotics research strives for deploying autonomous systems in populated environments, such as inner city traffic. Autonomous cars need a reliable collision avoidance, but also an object recognition to distinguish different ...
The knowledge-based search for water-related information system for the Mekong delta, Vietnam
(2014-03-14)
In recent years, the World Wide Web has strongly changed way of sharing and accessing data. Moreover, with new methods of data collection are developed we have much more data today. However, it is not straightforward to ...
Visibility Domains and Complexity
(2014-02-05)
Two problems in discrete and computational geometry are considered that are related to questions about the combinatorial complexity of arrangements of visibility domains and about the hardness of path planning under cost ...
Smoothed Analysis of Selected Optimization Problems and Algorithms
(2014-03-20)
Optimization problems arise in almost every field of economics, engineering, and science. Many of these problems are well-understood in theory and sophisticated algorithms exist to solve them efficiently in practice. ...
