History-based weighted average voter: A novel software voting algorithm for fault-tolerant computer systems (2001)
Presentation / Conference Contribution

Voting algorithms have been widely used in the realisation of fault-tolerant systems. We propose a new software voting algorithm which uses the history record of redundant modules to compute the final output. Two versions for the novel algorithm are...

Extensive and computationally complex signal processing and control applications are commonly constructed from small computational blocks where the load decomposition and balance may not be easily achieved. This requires the development of mapping an... Read More about Mapping and scheduling for heterogeneous architectures.

An open environment for the specification, design and code generation of control algorithms (1998)
Presentation / Conference Contribution

Proposals for an open, yet integrated, design environment to ease the design of complex process control systems are presented. A hierarchical approach to the allocation of computing resources is typically used in process control systems. The lower en...

Design tools for hybrid control systems (1997)
Book Chapter
Hajji, M., Bass, J., Browne, A., & Fleming, P. (1997). Design tools for hybrid control systems. . Springer. https://doi.org/10.1007/BFb0014717

Hybrid systems exhibit a variety of discrete and continuous behaviour. Extensions to the Development Framework, an environment for real-time control system design, are described here. These extensions allow the management of discrete events such as m... Read More about Design tools for hybrid control systems.

A proposed design environment for dependable embedded systems (1997)
Presentation / Conference Contribution

Proposals for an integrated design environment to ease the design of complex embedded systems are presented. Embedded systems are computer-based systems which must respond to external stimuli within time scales determined by the external environment....

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...
