Verified Emulation of Legacy Mission Computer Systems. Processor obsolescence is a serious maintenance problem for long-lived computer control systems in military aircraft and other critical applications. A promising solution is to interpose an emulator program between the original "legacy" software and a replacement processor. Unfortunately, no techniques exist for accurately verifying that this procedure preserves the original system's functional and timing behaviour. A particular challenge ....Verified Emulation of Legacy Mission Computer Systems. Processor obsolescence is a serious maintenance problem for long-lived computer control systems in military aircraft and other critical applications. A promising solution is to interpose an emulator program between the original "legacy" software and a replacement processor. Unfortunately, no techniques exist for accurately verifying that this procedure preserves the original system's functional and timing behaviour. A particular challenge is that processor emulations involve both legacy code and new subroutines, written in different programming languages. This project will enable verification of safety and mission-critical emulated systems by devising a multilingual modelling and reasoning formalism, based on program refinement theory.Read moreRead less

having efficient memory utilization, presents many challenging research
issues. This project will address these issues by extending a highly

Refinement of Temporal and Epistemic Specifications in Asynchronous Systems. Designing distributed systems is a complex activity requiring rigorous mathematical models of designs and specifications. It is desirable for the mathematical notations to be as close as possible to intuitive notions used by designers. One such notion is the idea that components in a distributed system have states of knowledge. Previous work has developed a calculus enabling derivation of systems with global clock by s ....Refinement of Temporal and Epistemic Specifications in Asynchronous Systems. Designing distributed systems is a complex activity requiring rigorous mathematical models of designs and specifications. It is desirable for the mathematical notations to be as close as possible to intuitive notions used by designers. One such notion is the idea that components in a distributed system have states of knowledge. Previous work has developed a calculus enabling derivation of systems with global clock by series of correctness-preserving transformations from a knowledge-based specification. This project will generalize this work to a calculus for systems that lack a global clock, and implement a tool providing automated support for use of the calculus.Read moreRead less
Redesigning Typesetting for the Digital Age: Multilingual Layout on Multiple Media. We propose to create and develop a new model for character-level automatic typesetting, much more flexible than existing approaches. This model will support quality typesetting of all of the modern - and many ancient - languages and scripts, on media such as paper, computer screen, paper maps and online maps, for regular and safety-critical applications.

This model will support quality typesetting of all of the modern - and many ancient - languages and scripts, on media such as paper, computer screen, paper maps and online maps, for regular and safety-critical applications.
The fundamental innovations in this proposal are the use of a tree-structured parameter space (generalization of Unix environment variables) and a multiple-pass approach to typesetting (as used in compilers). These innovative techniques will be integrated into computer software used worldwide.Read moreRead less

Maximising the benefits of limited resources is crucial for our industry, our hospitals, our security and our environment. This is achievable through a technology called combinatorial optimisation, which also supports wiser investment, better engineering, and even accelerated bio-informatics. Applying the technology is highly skilled and effort intensive, so most of its potential benefits are unrealised. This project will break down some of the barriers which make it hard to use. The ultimate goal is to let the user state the problem in simple terms, and the computer work out how best to solve it. Our vision is for groups and organisations large and small to reap the benefits of combinatorial optimisation.Read moreRead less
