Knowing Your Place in Real World Environments
The topic of mobile robot self-localisation is usually divided into the sub-problems of global localisation and position tracking. Both are now well understood individually, but few mobile robots can deal simultaneously with the two problems in large, complex environments. While eecient solutions have been found for metric maps, topological maps have, by nature of their compactness, the potenti...
متن کاملKnowing Your Place in the Real World
This paper addresses the scalability of existing techniques for mobile robot navigation to work in large, unstructured environments. In particular, we are interested in the problem of relocalisation after the robot has been placed at some arbitrary location (unknown to the robot) in a previously explored environment. In the rst instance, we assess the problems found when a system previously sho...

Status is the prominence, respect, and influence individuals enjoy in the eyes of others. Theories of positive illusions suggest that individuals form overly positive perceptions of their status in face-to-face groups.

Somatosensation is a broadly defined perceptual system that involves, among others, the experience of being touched or stroked on the skin, but also sensing temperature and feeling pain. In addition, somatosensat...
متن کاملThe Value of Knowing Your Enemy
Many auction settings implicitly or explicitly require that bidders are treated equally exante. This may be because discrimination is philosophically or legally impermissible, or because it is practically difficult to implement or impossible to enforce. We study so-called anonymous auctions to understand the revenue tradeoffs and to develop simple anonymous auctions that are approximately optim...
