Design and Analysis of Opaque Signatures
(2011-07-04)
Digital signatures were introduced to guarantee the authenticity and integrity of the underlying messages. A digital signature scheme comprises the key generation, the signature, and the verification algorithms. The key ......
The Efficient Discovery of Interesting Closed Pattern Collections
(2011-11-18)
Enumerating closed sets that are frequent in a given database is a fundamental data mining technique that is used, e.g., in the context of market basket analysis, fraud detection, or Web personalization. There are two ...
Surface Deformation Potentials on Meshes for Computer Graphics and Visualization
(2011-10-11)
Shape deformation models have been used in computer graphics primarily to describe the dynamics of physical deformations like cloth draping, collisions of elastic bodies, fracture, or animation of hair. Less frequent is ...
Modeling Visit Potential of Geographic Locations Based on Mobility Data
(2012-05-07)
Every day people interact with the environment by passing or visiting geographic locations. Information about such entity-location interactions can be used in a number of applications and its value has been recognized by ...
Reconstruction of Human Motions Based on Low-Dimensional Control Signals
(2012-08-09)
This thesis addresses the question to what extent it is possible to reconstruct human full-body motions from very sparse control signals.
To this end, we first investigate the use of multi-linear representations of ...

A Statically Typed Logic Context Query Language With Parametric Polymorphism and Subtyping
(2012-07-18)
The objective of this thesis is programming language support for context-sensitive program adaptations. Driven by the requirements for context-aware adaptation languages, a statically typed Object-oriented logic Context ...
Semantics-aware planning methodology for automatic web service composition
(2012-07-23)
Service-Oriented Computing (SOC) has been a major research topic in the past years. It is based on the idea of composing distributed applications even in heterogeneous environments by discovering and invoking network-available ......
Analysis of Trajectories by Preserving Structural Information
(2012-07-18)
The analysis of trajectories from traffic data is an established and yet fast growing area of research in the related fields of Geo-analytics and Geographic Information Systems (GIS). It has a broad range of applications ...
Experimental and numerical studies on solute transport in unsaturated heterogeneous porous media under evaporation conditions
(2012-08-31)
Groundwater level rise, root water uptake, or evaporation induces local upward water and solute fluxes in soils, causing soil salinization and rise of contaminants to the soil surface, and influencing the migration of ...
Design Rules in VLSI Routing
(2012-08-17)
One of the last major steps in the design of highly integrated circuits (VLSI design) is routing. The task of routing is to compute disjoint sets of wires connecting different parts of a chip in order to realize the desired ...
