Consider an infinite collection of particles travelling in d-dimensional Euclidean space and let Xn denote the initial position of the nth particle. Assume that the nth particle has through all time the random velocity Vn and that {Vn} is a sequence of dependent random variables. Let Xn(t) = Xn...

Consider a collection of vehicles on a highway. The velocity process of the kth vehicle is a Markov process with continuous paths independent of the velocity processes of the other vehicles but with the same probability law. The discharge of pollutants by the kth vehicle is described by a...
