: The problem of view updatesin deductive databasesis studiedby casting this in anaturally associatedabductive framework.It is shownthat this abductiveapproachdeals successfully, i...
We study generalized fixed-point equations over idempotent semirings and provide an efficient algorithm for the detection whether a sequence of Kleene's iterations stabilizes ...
Fast is a tool designed for the analysis of counter systems, i.e. automata extended with unbounded integer variables. Despite the reachability set is not recursive in general, Fast...
We consider the problem of simplifying a triangle mesh using edge contractions, under the restriction that the resulting vertices must be a subset of the input set. That is, contr...

Securing the mobile code commerce is not an easy task at all. We propose in this paper a framework to tackle this problem. In a first step, we analyse the general issues that must ...
