,Guards, Failure, and Partiality: Dijkstra’s Guarded-Command Language Formulated Topologically,t. We reexamine Dijkstra’s language, redefining its denotational semantics with powerdomains formulated in topological terms. The results refine existing work, give a sound semantics of guards, failure, and divergence for non-flat storage domains, and reveal the important role that general topology

Enhancing Top-Down Solving with Widening and Narrowing,In contrast to corresponding enhancements proposed for other standard fixpoint algorithms, no extra priorities on variables are required. Still, a mechanism can be devised so that occurrences of the widening/narrowing operator are inserted as well as removed dynamically.

Modal Intersection Types, Two-Level Languages, and Staged Synthesis,eory of subtyping and distributivity of the modal and intersection type operators. We describe how a stratification of . leads to a multi-linguistic framework for staged program synthesis, where metaprograms are automatically synthesized which, when executed, generate code in a target language. We s

,Last Mile’s Resources, the second analysis cannot be anticipated, because information about availability, implementation and other aspects of resources are unknown until the application is injected in the current environment.

,Static Timing Analysis – What is Special?,the properties of this application of abstract interpretation that differ from those in the standard applications of abstract interpretation in compilation and in verification. It also shows how some particular designs of the underlying abstract domains made efficient timing analysis possible.

Game Theory and Industrial Control Systems,optimisation to produce decision support tools to help system administrators optimise their investment in cyber defence. We will describe how our game theoretic work might be used to provide novel approaches to protecting ICS against cyber attacks.

,Probabilistic Abstract Interpretation: From Trace Semantics to DTMC’s and Linear Regression, (PAI) and statistical or linear regression analysis. While classical Abstract Interpretation, based on Galois connection, allows only for worst-case analyses, the use of the Moore-Penrose pseudo inverse in PAI opens the possibility of exploiting statistical and noisy observations in order to analyse and identify various system properties.
