Validation and Storage of Polyhedra through Constrained Delaunay Tetrahedralization
Abstract. Closed, watertight, 3D geometries are represented by polyhedra. Current data models define these polyhedra basically as a set of polygons, leaving the test on intersectin...

Adding a path connectedness operator to FO+poly (linear)
In the constraint database community, FO+poly and FO+linear have been proposed as foundations for spatial database query languages. One of the strengths of this approach is that t...

Progressive lossless compression of arbitrary simplicial complexes
Efficient algorithms for compressing geometric data have been widely developed in the recent years, but they are mainly designed for closed polyhedral surfaces which are manifold ...

Embedding Imperative Synchronous Languages in Interactive Theorem Provers
We present a new way to define the semantics of imperative synchronous languages by means of separating the control and the data flow. The control flow is defined by predicates th...
