Deterministic k-tape and multitape Turing machines with one-way, two-way and without a separated input tape are considered. We investigate the classes of languages acceptable by s...
We study the complexity of approximating the Stieltjes integral R 1 0 f(x)dg(x) for functions f having r continuous derivatives and functions g whose sth derivative has bounded va...
Abstract. In this paper, we introduce weak bisimulation in the framework of Labeled Concurrent Markov Chains, that is, probabilistic transition systems which exhibit both probabili...
This paper investigates the design and implementation of mobile computations in Java. We discuss various issues encountered while building a Java library that allows active objects...
Tilings of the plane by translation show interesting regularity in the disposition of the tiles: in particular, we point out that in the case of a single tile, the obtained congur...
