Application of the survey protocol for chytridiomycosis to Queensland, Australia.
Spread of the amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd), which causes chytridiomycosis, has resulted in the extinction of frogs, but the distribution of Bd is incompletely known. We trialled the survey protocol for Bd by attempting to systematically map its distribution in Queensland, Australia. Bd was easily detected in known infected areas, such as the Wet Tropics and South...

This document presents a formal abstract syntax in Z for fragments in the CARE language. Constraints are included which deene the \semantic checks" which deene well-formedness of fragments.

We have recently extended the sequential refinement calculus to handle real-time programs. A novel deadline command allows execution time limits to be expressed in a high-level language. The calculus allows refinement steps that separate timing constraints from non-timing requirements. Rules are provided for handling timing constraints, but the refinement of components implementing non-timing r...

This paper presents a framework for compositional verification of Object-Z specifications. Its key feature is a proof rule based on decomposition of hierarchical Object-Z models. For each component in the hierarchy local properties are proven in a single proof step. However, we do not consider components in isolation. Instead, components are envisaged in the context of the referencing super-com...

The demands placed on programmers by the needs of safety-critical systems mandate the use of formal methods, supported by an integrated toolkit, throughout software development. Many formal speciication, design and veriication techniques have been proposed in the past. As the next step in the maturation of these techniques we are aiming to integrate previously disparate methods. Our overall met...
