High-intensity transient signals.
An asymptomatic 33 year-old Caucasian male presented for routine imaging following a St. Jude's bi-leaflet aortic valve replacement some 6 months previously. The images show high-intensity transient signals (HITS) just below the aortic valve in both par-asternal and apical long axis views. The valve replacement otherwise appeared healthy. HITS are thought to be microbubbles which occur due to c...
متن کاملParameter Recovery for Transient Signals
Transient signals naturally arise in numerous disciplines for which the decay rates and amplitudes carry some informational significance. Even when the decay rates are known, solving for the amplitudes results in an ill-conditioned formulation. Transient signals in the presence of noise are further complicated as the signal-to-noise ratio asymptotically decreases in time. In this thesis the Dis...

متن کاملInterpreting signals from astrophysical transient experiments.
Time-domain astronomy has come of age with astronomers now able to monitor the sky at high cadence, both across the electromagnetic spectrum and using neutrinos and gravitational waves. The advent of new observing facilities permits new science, but the ever-increasing throughput of facilities demands efficient communication of coincident detections and better subsequent coordination among the ...
متن کاملBroadband matched-field processing of transient signals
Range and depth source localization in shallow water amounts to the estimation of the normalmode structure of the acoustic field. As "seen" by a vertical array, and from a modeling point of view, the normal-mode structure appears as a set of nonplane coherent waves closely spaced at a vertical angle. This paper presents a full-wave-field narrow-band high-resolution technique that uses the spect...
