A system for classification of mail pieces using range images is proposed. Position, orientation, size and shape parameters of volumetric models of single mail pieces are recovered using least squares minimization of a fitting function. The models are superquadrics with global deformations. The recovered parameters serve for classification. Comments University of Pennsylvania Department of Comp...

We consider the question whether top tennis players in a top tournament (Wimbledon) employ an optimal (efficient) service strategy. We show that top players do not, in general, follow an optimal strategy. The estimated inefficiencies are not large: the inefficiency regarding winning a point on service is on average 1.1% for men and 2.0% for women. Thus, by adopting an efficient service strategy...

This paper discusses the stability of algorithms for independent component analysis and the blind separation of signals. It builds on previous analysis of local asymptotic stability to present a simple, unifying view of the stability conditions and to provide a statistical interpretation of these conditions.

The number of independent countries has almost tripled since World War II: in 1946 there were 76 independent countries; today there are 193. Until recently, most countries had their own currencies. Hence, the expansion of the number of countries led to a proliferation of the number of currencies. More recently, however, the identification of currencies with countries has weakened, and the discu...
