We describe PLAYGROUND, an interactive game developed for demonstrating the concepts of goal recognition design (grd). grd is a recently formulated task that involves the off-line analysis of goal recognition models. As such grd involves formulating measures that assess the ability to perform goal recognition within a model and finding efficient ways to compute and optimize them. PLAYGROUND is ...

BACKGROUND Recess provides a daily opportunity for children to engage in moderate-to-vigorous (MVPA) and vigorous physical activity (VPA). Limited research has investigated the effects of recess-based interventions on physical activity using large sample sizes whilst investigating variables that may influence the intervention effect. The aim of the study was to investigate the short-term effect...

Objective: The purposes of this study were to: (a) learn if and how school based occupational therapists address the social participation needs of children with disabilities, (b) to learn if school based occupational therapists utilize the school playground to address the social participation of children with disabilities, (c) if so, to understand how occupational therapists utilize the school ...

In previous work with Pous, we defined a semantics for CCS which may both be viewed as an innocent presheaf semantics and as a concurrent game semantics. It is here proved that a behavioural equivalence induced by this semantics on CCS processes is fully abstract for fair testing equivalence. The proof relies on a new algebraic notion called playground, which represents the ‘rule of the game’. ...
