Abstract. Tree-walking automata (TWAs) recently received new attention in the fields of formal languages and databases. Towards a better understanding of their expressiveness, we c...
Abstract. We describe SAFL, a call-by-value first-order functional language which is syntactically restricted so that storage may be statically allocated to fixed locations. Evalua...
First-order translations have recently been characterized as the maps computed by aperiodic single-valued nondeterministic finite transducers (NFTs). It is shown here that this ch...

We show the decidability of model checking PA-processes against several first-order logics based upon the reachability predicate. The main tool for this result is the recognizabil...
We study the problem of strong/weak bisimilarity between processes of one-counter automata and finite-state processes. We show that the problem of weak bisimilarity between process...
We introduce a generic type system (based on Milner's sort system) for the synchronous polyadic -calculus, allowing us to mechanise the analysis of input/output capabilities o...
We consider the problem of scheduling n independent jobs on m identical machines that operate in parallel. Each job has a controllable processing time. The fact that the jobs have...
In this paper, we recall how the syntax of diagrams is captured by the diagram editor generator DIAGEN, and outline a visual, rule-based, and objectoriented programming language b...
