Abstract: This new CPS Synergy project is concerned with Management-Coupled Cyber and Physical Infrastructures (MCCPIs), which are infrastructures whose cyber- and physical- components are coupled by their wide-area management functions.  The main objective of the project is to develop a framework and tool set for threat assessment for MCCPIs which acknowledges their cyber, physical, and human elements, and to apply these tools and methods in a case study of the air traffic management system.  Three broad types of threats are considered: en

Abstract: The objective of this research is to develop tools for comprehensive design and optimization of air traffic flow management capabilities at multiple spatial and temporal resolutions: at a national airspace-wide scale and one-day time horizon (strategic time- frame); and at a regional scale (of one or a few Centers) and a two-hour time horizon (tactical time-frame). The following results were obtained in Year 4 of the project:

Abstract:  Understanding failure in protection system using Temporal Causal Diagrams  Situational  awareness  in  large  electrical  systems  and  eventual  fault  source  identification  and  possibly prognostics is a very challenging problem. State of the art relies on a network of protection devices that include relays to detect anomalies and engage circuit breakers to isolate the faulty component(s) in the system.
