Nondestructive Detection of Hollow Heart in Potatoes Using Ultrasonics
… were used to detect hollow heart in potatoes nondestructively. Fifty Russet Burbank potatoes were evaluated physically and sonically. A pair of dry-coupling 50-kHz ultrasonic transducers were used to generate an ultrasonic pulse with a power level of 0.22 W for the test of acoustic …

Nondestructive detection of foundation pile embedment depths for high mast light towers
Records of pile lengths are not available for several hundred high mast light towers (HMLTs) throughout Minnesota. The foundation systems, typically steel H-piles or concrete-filled steel pipe piles connected to a triangular concrete pile cap, risk overturning in the event of peak wind loadings if …

Probabilistic impact-echo method for nondestructive detection of defects around steel reinforcing bars in reinforced concrete
… assessment of engineered infrastructure using nondestructive testing (NDT) is critical to the proper scheduling of the maintenance and/or replacement of infrastructure components. In reinforced concrete structures, potentially adverse changes in the bond between concrete and reinforcing steel …

A photon-photon interface with an atomic ensemble in an optical cavity
… modes: an all-optical switch and transistor, a nondestructive photon detector, a phase shifter, and a quantum state generator. These devices rely on a nonlinear optical interface comprised of a few thousand atoms inside of a high-finesse optical cavity. Signal light is sent through a mode …
