Given changes in government and public attitudes to research funding, this will be an increasing concern in the near future. In this paper, we define a taxo...

With the rapid advancement of Formal Methods, Model-based Safety Analysis (MBSA) has been gaining tremendous attention for its ability to rigorously verify whether safety-critical scenarios are adequately addressed by design solution a cyber-physical human system.
