On the Axiomatizability of Impossible Futures: Preorder versus Equivalence
We investigate the (in)equational theory of impossible futures semantics over the process algebra BCCSP. We prove that no finite, sound axiomatization for BCCSP modulo impossible...

Fast positive-real balanced truncation of symmetric systems using cross Riccati equations
We present a computationally efficient implementation of positive-real balanced truncation (PRBT) for symmetric multiple-input multiple-output (MIMO) systems. The solution of a p...

Hybrid MPI-Thread Parallelization of the Fast Multipole Method
We present in this paper multi-thread and multi-process parallelizations of the Fast Multipole Method (FMM) for Laplace equation, for uniform and non uniform distributions. These ...

Pi-Calculus in Logical Form
Abramsky’s logical formulation of domain theory is extended to encompass the domain theoretic model for picalculus processes of Stark and of Fiore, Moggi and Sangiorgi. This is ...

The Rewriting Calculus as a Combinatory Reduction System
The last few years have seen the development of the rewriting calculus (also called rho-calculus or ρ-calculus) that uniformly integrates first-order term rewriting and λ-calcul...
