The composite signal flow model of computation targets systems with significant control and data processing parts. It builds on the data flow and synchronous data flow models ...
In this paper we present a formal approach to analyse performance for distributed systems, which is integrated in the early stages of the software development process. We propose ...
This paper deals with the modelling and evaluation of mission-phased systems devoted to space applications. We propose a two level hierarchical method that allows to model such sy...
