We present a viewing strategy for exploring the surface of an unknown object (i.e., making all of its points visible) by purposefully controlling the motion of an active observer. It is based on a simple relation between (1) the instantaneous direction of motion of the observer, (2) the visibility of points projecting to the occluding contour, and (3) the surface normal at those points: If the ...

This paper gives an overview of promising new developments in robust stability and performance analysis of linear control systems with real parametric uncertainty. The goal is to develop a practical algorithm for medium size problems, where medium size means less than 100 real parameters, and \practical" means avoiding combinatoric (nonpolynomial) growth in computation with the number of parame...

In the present study we use the property of some linguistic items to express more than one meaning in order to investigate whether there is semantic priming at the sentence level. To test such a priming effect we use the connective because that can express a causal or purposive relation. If there is a priming effect, then participants will be expected to use causal because following causal prim...
