Avionics and Airborne Computers: What Could Possibly Go Wrong?

Location: DAYSH 1.29 (please note an unusual venue!) Date/Time: 10th June 2015, 14:00 - 16:00
Speaker(s): Dr Steve Wright, University of the West of England.

Brief Description:In this talk, Dr Steve Wright looks at how an aircraft's avionics and their associated sensor/actuator systems can fail (and they do fail), and how these systems are designed to be resilient to these failures in hardware, software and architecture. The talk will include practical examples from aircraft industry history and Steve's own experience.

A behavioural model for the discussion of resilience, elasticity, and antifragility

Location: CLT 7.01 Date/Time: 16th June 2015, 14:00 - 15:00
Speaker(s): Vincenzo De Florio (University of Antwerp).

Brief Description:In this talk I tackle this problem by introducing a behavioural model of resilience. I interpret resilience as the property emerging from the interaction of the behaviours produced by two "players": a system and a hosting environment. The outcome of said interaction depends on both intrinsic and extrinsic factors, including the systemic "traits" of the system but also how the system's endowment matches the requirements expressed by the behaviours of the environment. I show how the behavioural approach provides a unifying framework within which it is possible to express coherent definitions for elasticity, change tolerance, and antifragility.
