A computational system is called autonomous if it is able to make its own decisions, or take
its own actions, without human supervision or control. The capability and spread of such …

Abstract Robonaut2 (R2) is a humanoid robot onboard the International Space Station (ISS),
performing specialized tasks in collaboration with astronauts. After deployment, R2 …

R2U2 is a modular runtime verification framework capable of monitoring sets of
specifications in real time and in resource-constrained environments. Such environments …

Legal properties involve reasoning about data values and time. Metric first-order temporal
logic (MFOTL) provides a rich formalism for specifying legal properties. While MFOTL has …

Experimental aerospace projects often require flight vehicle platforms for testing, such as
high-altitude balloons, sounding rockets, unmanned aerial systems (UAS), and CubeSats …

For developing safe automated systems, recognizing safety-critical situations in data from
their complex operational domain is imperative. This capability is, for example, essential …

Abstract Unmanned Aerial Systems (UAS) are quickly integrating into the National Air Space
(NAS). With the number of registered small (under 55 pounds) UAS in the USA alone at over …

When applying formal verification to a system that interacts with the real world, we must use
a model of the environment. This model represents an abstraction of the actual environment …

Signal-based temporal properties (SBTPs) characterize the behavior of a system when its
inputs and outputs are signals over time; they are very common for the requirements …

We take another look at intractable temporal logic specifications, where the intractability
stems from self-reference, unboundedness, or the need for explicit counting. A classic …
