Lamping's optimalgraph reduction technique for the -calculus is generalized to a new class of higher order rewriting systems, called Interaction Systems. Interaction Systems ...
This paper describes Bramble, a toolkit for constructing graphical editing applications. The primary focus of Bramble is improve support for graphical manipulation by employing di...
Databases are continuously evolving environments, where design constructs are added, removed or updated quite often. Research has extensively dealt with the problem of database evo...

We describe an extension of B-splines to surfacesof arbitrary topology, including arbitrary boundaries. The technique inherits many of the properties of B-splines: local control, ...
We prove formally that the first order theory of algebraically closed fields enjoy quantifier elimination, and hence is decidable. This proof is organized in two modular parts. We ...
