Landmine detection with a standoff acoustic/laser technique
… landmine threat. This paper explores a standoff acoustic/laser technique to discriminate landmines from other forms of man-made objects (clutter) in an urban environment. A novel approach currently under investigation by MIT Lincoln Labs, University of Mississippi, and other groups employs a …

Remote nondestructive evaluation of composite-steel interface by acoustic laser vibrometry
… of some form of nondestructive testing (NDT). Acoustic laser vibrometry is a relatively new method of NDT that shows a lot of promise in analysis of this interface. In this approach, an airborne acoustic wave is utilized to excite the location of the damage underneath the FRP sheets/plates and …

Detection of defects in FRP-reinforced concrete with the acoustic-laser vibrometry method
… advantageous. A novel approach called the acoustic-laser vibrometry method which is capable of remote assessment of damage in FRP-reinforced concrete, is investigated in this thesis. It exploits the fact that areas where the FRP has debonded from concrete will vibrate excessively compared …

Population-specific predictions for the finite Kuramoto model and collective synchronization in a system with resonant coupling
Synchronization of coupled simple harmonic oscillators is a well-studied problem in advanced undergraduate mechanics courses and the solution amounts to solving an eigenvalue problem. Synchronization of populations of auto-oscillators is a comparatively new field of study. The first scientists to …
