Wave Dispersion and Attenuation on Human Femur Tissue
Sensors, 2014 Cortical bone is a highly heterogeneous material at the microscale and has one of the most complex structures among materials. Application of elastic wave techniques to this material is thus very challenging.

Broadband Waveform Modeling Over a Dense Seismic Network [PDF]
, 2006 We developed a "two-way" calibration technique for studying clustered events, particularly their mechanisms and rupture directivities. First, we demonstrate that the magnitude 4 events with known source mechanisms can be used to calibrate the path ...

A fast Maximum Likelihood method for improving AMCW lidar precision using waveform shape
, 2009 Amplitude Modulated Continuous Wave imaging lidar systems use the time-of-flight principle to determine the range to objects in a scene. Typical systems use modulated illumination of a scene and a modulated sensor or image intensifier.

The imprint of crustal density heterogeneities on regional seismic wave propagation
, 2016 Density heterogeneities are the source of mass transport in the Earth. However, the 3-D density structure remains poorly constrained because travel times of seismic waves are only weakly sensitive to density.
