Abstract
A system and methods for alleviating an anomaly in a structure are presented. At least one anomaly detector structural member is embedded in the structure. A measurement signal is sent to the anomaly detector structural member and a feedback signal is received from the anomaly detector structural member in response to the measurement signal. A difference between the measurement signal and the feedback signal is calculated to determine a change in the structure, and at least one non-optimal event is identified in real-time if the change exceeds an event threshold.
