Boss is an autonomous vehicle that uses on-board sensors (global positioning system, lasers, radars, and cameras) to track other vehicles, detect static obstacles, and localize itself relative to a road model. A three-layer planning system combines mission, behav-ioral, and motion planning to drive in urban environments. The mission planning layer considers(More)

An emerging approach to teaching young people about sustainability is the use of immersive game spaces and virtual environments. This project focuses on children's virtual worlds with an environmental values orientation to examine the ways these worlds work as vehicles of sustainability literacy. These worlds position themselves explicitly as ethical and(More)
We tested the effects of variation of stimulus onset asynchrony (SOA) on visual working memory (WM) performance across different load levels and the underlying brain activation patterns using functional magnetic resonance imaging (fMRI) in 48 healthy participants. Participants were instructed to memorise arrays of coloured squares and had to perform a(More)
Executive Summary The Urban Challenge represents a technological leap beyond the previous Grand Challenges. The challenge encompasses three primary behaviors: driving on roads, handling intersections and maneuvering in zones. In implementing urban driving we have decomposed the problem into five components. Mission Planning determines an efficient route(More)
