Abstract: Methods, systems, and computer-readable media are disclosed herein combine randomization functionalities with the machine-learning prioritization of workflows for performance testing. In aspects, a primary workflow having a sequence of user interface steps is input. Testing workflows are generated that represent each variable position of unlocked steps in the sequence of the primary workflow while maintaining the sequential position of any locked steps. These testing workflows are then ingested to a machine learning model that identifies as subset of the testing workflows to prioritize over other. Specifically, testing workflows are prioritized that at least partially match sequence patterns in historical workflow data that is associated with vulnerable computer code. The subset is output and tested by testing engine to generate a report of any vulnerable computer code.

Abstract: Methods/systems for monitoring fault duration in circuit interrupt devices perform edge detection using a second time derivative of a current or voltage waveform. The second derivative reveals peaks that may be used to establish starting and ending times for the fault duration. In some embodiments, the second derivatives are derived only for portions of the waveform within time windows that enclose the fault duration starting and ending times, respectively. The above arrangement provides a consistent way of determining durations of transitory events, such as durations of faults, and the like, that does not rely on waveform zero-crossings. The duration determinations may be implemented locally within a device, and/or the device may acquire and transfer underlying waveform data to an external system for the duration determinations. Data from multiple devices may be collected over time for analysis and modeling to provide remote support and monitoring of local devices via digital twins.
