Concurrent and distributed systems have traditionally been modelled using nondeterministic transitions over configurations. The minism provides an abstraction over scheduling, net...
Abstract. We develop a variant of Gordon and Hankin's concurrent object calculus with support for flexible access control on methods. We investigate safe administration and ac...
In this work we discuss a number of issues for the design of hypertext systems in an actor-based model of computation. We examine how the "traditional" basic concepts whi...
Abstract. Many long-lived and distributed systems must remain available yet evolve over time, due to, e.g., bugfixes, feature extensions, or changing user requirements. To facilit...
