Soundness proofs of program logics such as Hoare logics and type systems are often made easier by decorating the operational semantics with information that is useful in the proof...
Attempts to use finite models to guide the search for proofs by resolution and the like in first order logic all suffer from the need to trade off the expense of generating and m...
This system paper reports on some of the advantages tangible interaction can bring to chemistry education. The paper describes the realisation of an in-house designed Tangible Use...
