We explore the implications of supporting bags (i.e. multisets) in a data model and associated query language, and present some formal results concerned with the algebraic propert...
Requirements from new types of applications call for new database system solutions. Computational science applications performing distributed computations on Grid networks with req...
Abstract. In this paper we present a novel approach to big-step operational semantics. This approach stems from the observation that the typical type soundness property formulated ...
Session types support a type-theoretic formulation of structured patterns of communication, so that the communication behaviour of agents in a distributed system can be verified ...
Numerical modelling is now used routinely to make predictions about the behaviour of environmental systems. Model calibration remains a critical step in the modelling process and ...
