Razi Ahmed, 2022, "A microwave photonic receiver for high performance radars", https://doi.org/10.48577/jpl.P82OII, Workshop on Nonlinear and Quantum Optics, JPL Open Repository
A resonant photonic receiver is designed to efficiently upconvert a weak microwave signal, such as a return signal of a millimeter-wave radar, to optical frequency domain and then transfer this signal to an intermediate microwave frequency, convenient for further processing. Such... |

Klaus Havelund, 2022, "Runtime Verification as Documentation", https://doi.org/10.48577/jpl.TZVKY7, ISoLA 2022 - 11th International Symposium On Leveraging Applications of Formal Methods, Verification and Validation, JPL Open Repository
In runtime verification, a monitor is used to return a Boolean verdict on the behavior of a system. We present several examples of the use of monitors to instead document system behavior. In doing so, we demonstrate how runtime verification can be combined with techniques from da... |
