The expressiveness of models of concurrency has intrigued researchers for a number of years now. In particular, studies on the expressiveness of process calculi (such as CCS and the pi-calculus) have had considerable impact. The interest is in questions such as, e.g., under what conditions two process languages C ...

# Investigating Cooperative Scheduling in Parallel and Distributed Systems

Our ongoing work focuses on an efficient solution to implement cooperative scheduling models through a user-friendly library written using Java 8. This library translates code written in a modelling language named the Abstract Behavioural Specification Language, into executable Java code. We investigate the issues raised by nested parallelism and the ...

In this talk we will define the notion of equations and coequations for deterministic automata and, with the aid of some examples, we define what it means for a deterministic automaton to satisfy a set of equations or coequations. We will show a correspondence between sets of equations and coequations ...

read more# Composing Constraint Automata, State-by-State

When composing Constraint Automata by means of the product, one can run into cases where the amount of resources necessary grows exponentially in the number of automata. If the Constraint Automaton being calculated requires an exponential number of states by its very nature, this is not surprising. However, there are ...

read more# eScience, Theory and Experience

eScience, or enabling science, involves the theory and practice of how to enable scientists from different domains to take advantage of the latest advancements in computer science and technology. This is mainly achieved via science gateways, also known as virtual research environments, which hide the technical details of accessing and ...

read more# Virtual Prototyping for Cyber Physical Systems

Virtual Prototyping is the technology that makes it possible to develop a virtual prototype of a system under design and explore the system design space, including hardware and software. The real application software can be run over the virtual prototype platform and outputs the same results as the real system ...

read more# A new method for verification of transition systems is presented - part 2

The state space of a transition system is defined as a quotient set (i.e. a set of equivalence classes) of terms of a top most sort State, and the transitions are defined with conditional rewrite rules over the quotient set. A property to be verified is either (1) an ...

read more# Quantitative formalisms of regularity, a partial survey

Abstract. The question of extending the concept of regularity to a more quantitative setting has been considered since the origins of formal language theory and a large number of solutions to this question have been proposed. In in this lecture, I will review only a part of them. First, I ...
