A new approach to road safety – road danger reduction and Bristol Council UK Open
Although in industrialised countries recent reductions in road casualties look encouraging, this reduction is partly due to decreased exposure to the road environment as fewer people walk and cycle. This reduction in walking and cycling ha…
Psychological associations with emotionalism after stroke Open
The psychological associations with emotionalism were examined, 1 month after stroke, in 448 stroke survivors who met inclusion criteria for a randomised trial of psychological treatment. One hundred and one (21.5%) patients had emotionali…
Goal-directed, dynamic animation of human walking Open
This paper presents a hybrid approach to the animation of human locomotion which combines goal-directed and dynamic motion control. Knowledge about a locomotion cycle is incorporated into a hierarchical control process. The desired locomot…

Multiprocessor experiments for high-speed ray tracing Open
New single- and multiprocessor models for ray tracing are presented. Important features are (1) the use of custom VLSI building blocks, (2) the use of a modified hierarchical data-structure-based ray tracing algorithm with three disjoint d…
The integration of subjective and objective data in the animation of human movement Open
Animation of human movement can be based either on analog inputs derived directly from actual movements or on symbolic inputs chosen to produce the desired movement. The former type of input can be quite accurate and objective but is a des…
Projections of multidimensional data for use in man-computer graphics Open
The utility of man-computer graphics as an engineering design tool is now well recognized. With the use of an interactive visual display it is possible for a designer to input information graphically or digitally, observe the results of hi…
