We present a new 3D shape descriptor based on conformal geometry. Our descriptor is invariant under non-rigid quasi-isometric transformations, such as pose changes of articulated ...
The open, decentralized nature of the Semantic Web demands fundamental changes in our approach to ontology development and deployment. To maximize the expressiveness and robustnes...

In this paper we present an extension to the classical particle system. We unify particles, particle sources, and force generators into a second order particle system. In the seco...
In this paper we present meta-rules to express an infinite class of semantically related graph transformation rules in the context of pure topological modelling with G-maps. Our p...
In this paper, we report findings on how user behaviors vary in tasks with different difficulty levels as well as of different types. Two behavioral signals: document dwell time a...
