Abstract: Provided herein are systems and methods for real time processing of signals from an array of transducers for detecting transient elastic waves originating from unknown locations in a body, which may propagate in a dispersive fashion. The systems and methods allow real time combination and analysis of signals, including decisions regarding storage as new data is received. The methods described herein include designing arrays of detectors and methods for processing signals in real time given the constraints of the body under test determining whether to store the set of information while a new set of information is received for processing within a real time environment. The methods described herein include methods which result in the determination or small time shifts which place all signals into a coherent time base which are then combined achieving a composite waveform that possesses an increased signal-to-noise ratio over any single element.

Abstract: Provided herein are systems and methods for achieving an extended service life for a pressure vessel that has experienced a prior service life. In some embodiments, the service life of the vessel has expired. The service vessel has an unknown damage condition, including defects sustained during the service life. Despite these defects and unknown accumulated damage state, the embodiments described herein may be used to test these vessels, to safely pressurize the vessels beyond pressures deemed safe for the vessel to experience in its damaged state, and to recommission a new service life for the vessel. The recommissioning of the vessel for an additional service interval may include meeting certain requirements for the pressure vessel, and embodiments described herein include exemplary measurements and observations to assure these requirements of the rejuvenated vessel are met.
