Experimental comparison of voting algorithms in cases of disagreement (1997)
Presentation / Conference Contribution

Voting algorithms are used to mask erroneous results from redundant subsystems (variants) in fault tolerant systems. While voting algorithms are well known and widely used, the authors are not aware of any detailed investigation of voter behaviour in...

Testing fault-tolerant systems using a unified error model (1997)
Presentation / Conference Contribution

This paper presents a method of designing test data based around a unified error model. The model allows error 'surfaces' to be defined for a given application, and used to define a test region(s) that give a measure of test coverage. The paper appli...

A study of smoking, alcohol and social class as risk factors for stroke in Northwest of England (1996)
Presentation / Conference Contribution

The validation of formal specifications of requirements (1996)
Presentation / Conference Contribution

We review the approaches put forward to validate formal specifications of requirements, drawing a parallel with research into the validation of knowledge bases. Using an industrial-scale case study we describe a partially implemented, integrated envi... Read More about The validation of formal specifications of requirements.

Error model for computer control systems (1996)
Presentation / Conference Contribution

This paper presents an error model that is intended to allow the dependability of computer control systems, with fault tolerant mechanisms included, to be evaluated. The model allows error `surfaces' to be defined for a given application, and used to... Read More about Error model for computer control systems.

Case control study of stroke and quality of hypertension control in Northwest of England (1996)
Presentation / Conference Contribution

Prevalence, treatment, control and awareness of high blood pressure among first-ever stroke patients in Northwest England (1996)
Presentation / Conference Contribution

The development framework: Work in progress towards a real-time control system design environment (1996)
Presentation / Conference Contribution

This paper describes work in progress on two extensions to the environment of a Development Framework for the design of control system software; hybrid system design and design of dependable systems. The Development Framework automatically converts a... Read More about The development framework: Work in progress towards a real-time control system design environment.

Intelligent voting strategies for dependable real-time control systems (1995)
Presentation / Conference Contribution

An intelligent and dependable voting mechanism for use in real-time control applications is presented. Strategies proposed by current safety standards advocate N-version software to minimise the effects from undetected software design faults (bugs)....

Dependability modelling in a prototype Development Framework (1995)
Presentation / Conference Contribution

The Development Framework provides a highly automatic translation from a specification to an implementation. The specification is in a popular, graphical control engineering notation typically representing a system with stringent reliability requirem...

Prototype framework of tools for the design of real-time distributed control software (1994)
Presentation / Conference Contribution

A prototype framework of software tools for the design of distributed real-time control system software is described here. The tools provide a highly transparent transformation from a specification to an implementation. The specification is in a fami...

Prototype framework of design tools for computer-aided control engineering (1994)
Presentation / Conference Contribution

This paper introduces a framework of tools which allow the design of distributed, potentially fault-tolerant, real-time control software. This framework takes a system specified in the control engineering domain and translates this application-orient...

Voting Software for Fault-Tolerant Aircraft Flight Control Systems (1992)
Presentation / Conference Contribution

An intelligent and robust voting service is proposed. The novel voting service, is capable of forming a consensus based on performance of redundant applications in the value, time and reliability domains. The voter is distributed using a hot backup a...

Embedding employability into an active learning curriculum
Presentation / Conference Contribution

In a globalised environment there is high competition as well as significant opportunities. It is
essential that university graduates are industry ready, equipped with the necessary
professional and technical skills. This study investigates the rel... Read More about Embedding employability into an active learning curriculum.

Workshop – building interdisciplinary working across the University
Presentation / Conference Contribution

Lockdown learning… an interdisciplinary approach
Presentation / Conference Contribution

2020 will be remembered as a critical turning point for Education. An unpredicted pandemic took nations leaders by surprise and led to freedoms we had become accustom to, being suspended. The response from education was to diversify into virtual/blen... Read More about Lockdown learning… an interdisciplinary approach.

Eating as a means to combat distress: A novel pathway to explain the association between household food insecurity and food choice
Presentation / Conference Contribution

Food insecurity is a lack of the financial resources needed to ensure reliable access to food to meet dietary, nutritional, and social needs. In the UK, 8.4 million people were food-insecure in 20141. Household food insecurity is associated with poor...
