Interval temporal logics are expressive formalisms for temporal representation and reasoning, which use time intervals as primitive temporal entities. They have been extensively studied for the past two decades and successfully applied in AI and computer science. Unfortunately, they lack the ability of expressing promptness conditions, as it happens with the commonly-used temporal logics, e.g.,...

A second order linear scalar diierential equation including a zero-th order term is approximated using rst the standard Galerkin method enriched with bubble functions. Static condensation of the bubbles suggest an unusual stabilized nite element method for which we establish a convergence study and obtain successful numerical simulations. The method is generalized to allow for a convection oper...

A permanent, full-time instrument for prompt-gamma activation analysis is nearing completion as part of the Cold Neutron Research Facility (CNRF). The design of the analytical system has been optimized for high gamma detection efficiency and low background, particularly for hydrogen. Because of the purity of the neutron beam, shielding requirements are modest and the scatter-capture background ...

This study examines phonological and phonetic properties of contrastive referential expressions. An interactive holiday tree decoration task provided sequences of ornaments to prompt production of target noun phrases in spontaneous conversation. This paper presents an analysis of a subset of referential expressions that were uttered in contrastive discourse contexts, focusing on the production ...
