The contribution of the paper is twofold. First, we define a general notion of type system equipped with an entailment relation between type environments; this generalisation serv...
Aspect-Oriented Programming (AOP) has been proposed as a methodology that provides new modularization of software systems by allowing encapsulation of cross-cutting concerns. Aspe...
Sensor networks are one important building block towards the realisation of context-aware applications. Suitable communication protocols and middleware solutions are necessary to ...
The interest is in characterizing insightfully the power of program self-reference in effective programming systems (epses), the computability-theoretic analogs of programming lan...
