OBJECTIVE Introducing message prompts at the 'point-of-choice' (POC) between stairs and escalators increases stair choice in 'public-access' settings (e.g. malls). For nationwide campaigns, plentiful POCs appear needed. We audited the availability of POCs in public-access settings across England. METHODS Boundaries for 25 urban areas (population=6,829,874) were verified using Ordinance Survey...

This thesis studies the performance of both opportunistic spectrum access (OSA) and spectrum sharing (SS) cognitive radio networks (CRNs) using cross-layer design (CLD) approaches in order to provide reliable and optimum packet transmission at the medium access control (MAC) layer with quality of service (QoS) guarantees, to optimize the secondary user (SU) performance given the primary user (P...
