We present four coinductive operational semantics for the While language accounting for both terminating and non-terminating program runs: big-step and small-step relational semant...
We propose a new grouping operator for logic programs based on the group_by operator of SQL. The novelty of our proposal lies in the use of modes, which allows us to relax some rat...
Abstract. The importance of modularity in product innovation is analyzed in this paper. Through simulations with an agent-based modular economic model, we examine the significance...
We study the impact on observational semantics for SOC of priority mechanisms which combine dynamic priority with local pre-emption. We define manageable notions of strong and wea...

It is important for programs to have modular correctness properties. We look at non-deterministic programs expressed as termrewriting systems which compute normal forms of input t...
