We introduce Isabelle/UTP, a novel mechanisation of Hoare and He's Unifying Theories of
Programming (UTP) in Isabelle/HOL. UTP is a framework for the study, formalisation, and …

We describe an approach to the model-based engineering of embedded and cyber-physical
systems, based on the semantic integration of diverse discipline-specific notations and tools …

When designing highly interactive distributed systems such as e-learning environments, a
system-of-systems (SoS) perspective enables dynamic adaptation to situations of use and …

We describe our work on a UTP semantics for the dynamic systems modelling language
Modelica. This is a language for modelling a system's continuous behaviour using a …

We describe the denotational semantics of a subset of the COMPASS Modelling Language
(CML), using Hoare & He's Unifying Theories of Programming. The subset consists of rich …

This is an introduction to mechanised theory engineering in Isabelle, an LCF-style
interactive theorem prover. We introduce an embedding of Hoare & He's Unifying Theories …

of data interopera. bility. However, today, information ecosystems in which organizations are …

Building Systems of Systems (SoS) has gained momentum in various domains. Today,
complex applications require to let several systems developed independently cooperate …

The US Navy understands full spectrum cyber warfare and is devoted to discovering where
