We introduce and study Recursive Markov Chains (RMCs), which extend ordinary finite state Markov chains with the ability to invoke other Markov chains in a potentially recursive m...
Term equations involving individual and sequence variables and sequence function symbols are studied. Function symbols can have either fixed or flexible arity. A sequence variabl...
Abstract. Code obfuscations are semantics-preserving code transformations used to protect a program from reverse engineering. There is generally no expectation of complete, long-te...
Abstract. Matching is a basic operation extensively used in computation. Second-order matching, in particular, provides an adequate environment for expressing program transformatio...
This paper studies the problem of resource availability in the context of mobile code for embedded systems such as smart cards. It presents an architecture dedicated to controlling...
