A formally verified compiler back-end [PDF]

, 2008
This article describes the development and formal verification (proof of semantic preservation) of a compiler back-end from Cminor (a simple imperative intermediate language) to PowerPC assembly code, using the Coq proof assistant both for programming ...

Feature refinement [PDF]

, 2007
Development by formal stepwise refinement offers a guarantee that an implementation satisfies a specification. But refinement is frequently defined in such a restrictive way as to disallow some useful development steps.

On More or Less Appropriate Notions of ‘Computation’

South African Computer Journal, 2018
Half a century after the emergence of computer science (a.k.a. informatics) as an academic discipline, the notion of “computation” is not yet “settled”. On the contrary: recent developments in the natural sciences, in mathematics, as well as in computer ...

A robust semantics hides fewer errors [PDF]

, 2009
In this paper we explore how formal models are interpreted and to what degree meaning is captured in the formal semantics and to what degree it remains in the informal interpretation of the semantics.

Neurolinguistics Research Advancing Development of a Direct-Speech Brain-Computer Interface

iScience, 2018
A direct-speech brain-computer interface (DS-BCI) acquires neural signals corresponding to imagined speech, then processes and decodes these signals to produce a linguistic output in the form of phonemes, words, or sentences.

The global environmental agenda urgently needs a semantic web of knowledge

Environmental Evidence, 2022
Progress in key social-ecological challenges of the global environmental agenda (e.g., climate change, biodiversity conservation, Sustainable Development Goals) is hampered by a lack of integration and synthesis of existing scientific evidence.

Conceptualising Programming Language Semantics

Philosophies
The semantics of programming languages tend to be discussed with high levels of formality; much of the previous research—both philosophical and historical—has investigated them from this perspective.

A Theory of Sampling for Continuous-time Metric Temporal Logic

, 2009
This paper revisits the classical notion of sampling in the setting of real-time temporal logics for the modeling and analysis of systems. The relationship between the satisfiability of Metric Temporal Logic (MTL) formulas over continuous-time models and
