Lighthouse: A spacebased mission concept for the surveillance of geosynchronous space debris from low earth orbit [PDF]

, 2018
In this paper, a new mission is proposed for space debris surveillance in geosynchronous orbit (GEO). The mission "Lighthouse", here proposed as a concept study, describes the use of a small satellite in a low polar orbit, equipped with a Schmidt ...

Use of spatiotemporal analysis of laboratory submission data to identify potential outbreaks of new or emerging diseases in cattle in Great Britain. [PDF]

, 2011
BACKGROUND: New and emerging diseases of livestock may impact animal welfare, trade and public health. Early detection of outbreaks can reduce the impact of these diseases by triggering control measures that limit the number of cases that occur.

Learning object behaviour models [PDF]

, 1998
The human visual system is capable of interpreting a remarkable variety of often subtle, learnt, characteristic behaviours. For instance we can determine the gender of a distant walking figure from their gait, interpret a facial expression as that of ...
