Modeling automation within an abstraction hierarchy

Radio forensics could unmask nearby off-axis gamma-ray bursts

“…Swift/UVOT began observations 67 s after the trigger, but found no UV counterpart down to a limiting magnitude of 19.6 mag with its White filter Emery & Gropp 2017). Several optical telescopes followed up the event, including the 0.5m robotic telescope D50 (Trobl et al 2017), Zeiss-1000 (East) of Tien Shan Astronomical Observatory and AZT-8 telescope of CrAO (Mazaeva et al 2017b), and the Reionization and Transients Infrared Camera (RATIR) on the 1.5m Harold Johnson Telescope at the Observatorio Astronomico Nacional (Butler et al 2017). These observations rule out a GW170817-like kilonova within 1 Gpc.…”

“…Swift/UVOT began observing 66 s after the trigger, but found no credible optical counterpart but found no UV counterpart down to a limiting magnitude of 19.6 mag with its White filter (Siegel & Mingo 2017). The event was followed up by optical telescopes, including the 60-cm robotic telescope REM located at the La Silla Observatory (D'Avanzo et al 2017), the MASTER robotic telescope (R. Podesta et al 2017), RATIR (Troja et al 2017b), and the AS-32 (0.7m) telescope of Abastumani Observatory (Mazaeva et al 2017a). The most sensitive of these observations was RATIR's that reached 19 mag in the r, i, Z and Y bands about 3 hours after the burst.…”

Identifying Problems and Generating Recommendations for Enhancing Complex Systems: Applying the Abstraction Hierarchy Framework as an Analytical Tool

“…Because functional purposes and abstract functions are global and can be shared by other domain subsystems and components, higher order "aircraft" level functions can be linked to specific functional structures of the automation. Thus, this approach also illustrates how automation is integrated into the AH modeling of an overall work domain (i.e., the aircraft being controlled in this case), which has been recently explored by other studies (Ho & Burns, 2003;Mazaeva & Bisantz, 2003).…”
