Kinetic bounding volume hierarchies for deformable objects
We present novel algorithms for updating bounding volume hierarchies of objects undergoing arbitrary deformations. Therefore, we introduce two new data structures, the kinetic AAB...

Star-contours for efficient hierarchical self-collision detection
Collision detection is a problem that has often been addressed efficiently with the use of hierarchical culling data structures. In the subproblem of self-collision detection for ...

Modeling relational events via latent classes
Many social networks can be characterized by a sequence of dyadic interactions between individuals. Techniques for analyzing such events are of increasing interest. In this paper,...

Ubiquitous Parameterization - Invitation to Fixed-Parameter Algorithms
Abstract. Problem parameters are ubiquitous. In every area of computer science, we find all kinds of “special aspects” to the problems encountered. Hence, the study of paramet...

An Unfolding Algorithm for Synchronous Products of Transition Systems
Abstract. The unfolding method, initially introduced for systems modelled by Petri nets, is applied to synchronous products of transition systems, a model introduced by Arnold [2]....
