Static program analysis has become an essential tool for developers to find and avoid bugs as well as security vulnerabilities. This is particularly important for applications requiring formal verification, e.g., safety- or security-critical ...

This paper proposes a formal framework for minimizing, analyzing and verifying stochastic process algebraic models using tools and techniques developed for the state-labeled domain, and vice versa. First, we modify the model embeddings proposed in the ...

As the development of autonomous vehicles progresses, efficient safety assurance methods become increasingly necessary. Safety assurance methods such as monitoring and scenario-based testing call for formalisation of driving scenarios. In this paper, we ...

Concrete domains have been introduced in description logic (DL) to enable reference to concrete objects (such as numbers) and predefined predicates on these objects (such as numerical comparisons) when defining concepts. The primary research goal in this ...

Metrics such as accuracy, precision, recall, F1 score, etc. are generally used to assess the performance of machine learning (ML) models. From a safety perspective, relying on such single point estimates to evaluate safety requirements is problematic ...

In this paper, we propose a machine-independent logic to verify concurrent machine code running on a single-core machine, using a combination of separation logic and rely/guarantee reasoning. Separation logic is employed to reason about local resources, ...
