Books and magazines often contain pages containing audacious mixtures of color images and text. Our problem consists in coding the background colors of a such documents without wa...
This paper addresses the complexity of computing the smallest-radius infinite cylinder that encloses an input set of n points in 3-space. We show that the problem can be solved in...
A trigger system in High Energy Physics Experiments (HEPE) has to decide, in few µs, if the data related to a nuclear event have to be stored or not. Normally, these data, are co...
