Stiction in control loops lead to oscillations and loss of productivity. Timely detection of stiction in control valves can be used in scheduling valve maintenance and deployment of compensation techniques to reduce their impact. Several approaches have been proposed for detection of stiction. Data-based approaches use unique shapes of the PV and OP data to(More)
Sense-response applications are widely being used for safeguarding critical infrastructure. In such applications, the sensor nodes detect and report events of interest to the base-station which promptly responds with a physical response. A concern that arises immediately is regarding the ability of the sensor nodes to encounter malicious entities that(More)
