Requirements formalization has become increasingly popular in industrial settings as an
effort to disambiguate designs and optimize development time and costs for critical system …

Differential dynamic logic (dL) is a formal framework for specifying and reasoning about
hybrid systems, ie, dynamical systems that exhibit both continuous and discrete behaviors …

Abstract Mission-time Linear Temporal Logic (MLTL) represents the most practical fragment
of Metric Temporal Logic; MLTL resembles the popular logic Linear Temporal Logic (LTL) …

Safety-critical infrastructures must operate in a safe and reliable way. Fault tree analysis is a
widespread method used for risk assessment of these systems: fault trees (FTs) are required …

Differential temporal dynamic logic dTL2 is a logic to specify and verify temporal properties
of hybrid systems. It extends differential dynamic logic (dL) with temporal operators that …

In this thesis we present an approach to apply formal analysis methods in order to improve
the quality of requirements. The approach enables the application of formal analysis …

The ongoing efforts to deploy safety-critical autonomous robots that operate in semi-
structured, dynamic, and uncertain environments, reinforce the importance of supplementing …

Like software, requirements evolve and change frequently during the development process.
Refactoring is the process of reorganising software without changing its behaviour, to make …

When considering risky events or actions, we must not downplay the role of involved objects:
a charged battery in our phone averts the risk of being stranded in the desert after a flat tyre …

Mission-time Linear Temporal Logic (MLTL) is rapidly increasing in popularity as a
specification logic, eg, for runtime verification, model checking, and other formal methods …
