Mobile Ambients (MA) have acquired a fundamental role in modelling mobility in systems with mobile code and mobile devices, and in computation over administrative domains. We pres...
This paper presents a framework to define a semantics for a real-time object-orientation programming language and to verify programs written in the language. The semantics is defi...
We examine the power of incremental evaluation systems that use an SQL-like language for maintaining recursively-de ned views. We show that recursive queries such as transitive clo...
This paper considers the theory of database queries on the complex value data model with external functions. Motivated by concerns regarding query evaluation, we first identify re...
Timed Interval Calculus (TIC) is a highly expressive set-based notation for specifying and reasoning about embedded real-time systems. However, it lacks mechanical proving support...
