Peers in peer-to-peer file-sharing systems use conjunctive queries as a way of controlling query cost in the absence of information about the behavior of other peers. Conjunctive ...
We show that typability for a natural form of polymorphic recursive typing for rank-2 intersection types is undecidable. Our proof involves characterizing typability as a context ...
Presently, there is no satisfactory model for dealing with political autonomy of agents in policy based management. A theory of atomic policy units called ‘promises’ is therefo...
We present Scilog, an experimental knowledge base to facilitate scientific discovery and reasoning. Scilog extends Prolog by supporting (1) dedicated predicates for specifying and ...
