Computing the exact arrangement of circles on a sphere, with applications in structural biology: video
The Bentley-Ottmann (BO) algorithm, initially designed to report the intersection points of line-segments in the plane, is the prototypical sweep-line algorithm. This video presen...

Two Linear-Time Algorithms for Computing the Minimum Length Polygon of a Digital Contour
The Minimum Length Polygon (MLP) is an interesting first order approximation of a digital contour. For instance, the convexity of the MLP is characteristic of the digital convexit...

A New Type of Size Function Respecting Premeshed Entities
This paper describes the creation of a new type of size function – the mesh size function that honors the existing mesh on premeshed geometry entities and radiates the mesh size...

A Proof of Regularity for Finite Splicing
We present a new proof that languages generated by (non extended) H systems with finite sets of axioms and rules are regular.

Hierarchical Correctness Proofs for Distributed Algorithms
Abstract: We introduce the input-output automaton, a simple but powerful model of computation in asynchronous distributed networks. With this model we are able to construct modular...
