Defunctionalization is generally considered a whole-program transformation and thus incompatible with separate compilation. In this paper, we formalize a modular variant of defunctionalization which can support separate compilation for a functional programming language with parametric polymorphism. Our technique allows modules in a Haskell-like language to be separately defunctionalized and com...

We study the problem of finding best approximate circuit that is closest (in some pertinent metric) to a target circuit, and which satisfies number hardware constraints, like gate alphabet connectivity. look at in CNOT+rotation set from mathematical programming standpoint, offering contributions both terms understanding mathematics its efficient solution. Among results we present, are able deri...

This paper summarises the results of several studies of individual differences among users navigating in virtual environments. These differences relate to performance of navigational tasks, and the degree of sense of presence experienced by the users. The individual differences addressed in this paper refer primarily to personality and demographic factors. The possibility of improving the desig...
