SIAM Journal on Applied Mathematics, Vol. 79, No. 6 (2019), pp. 2663-2687 (25 pages) We analyze sound propagation in a waveguide filled with a random medium modeled by small-amplitude spatial and ...

The Doppler effect, discovered in 1842 by Christian Doppler, is familiar to most of us; stationary observers of waves such as sound waves will see wavelengths that depend on the relative motion ...

Handheld devices can scan the lower limbs of a patient and 'listen' to the blood flow, providing vital early indication of problems that could lead to strokes or heart attacks. But inexperience or ...

This study investigates a key aspect of how ambient flow affects the recruitment of water-dispersed marine larvae onto benthic substrata: the sweeping away of larvae that have landed on surfaces.

Above: A platform designed to stabilize a large Doppler lidar as it operates inside an airplane flying through a hurricane. You wouldn’t dream of flying through a hurricane, would you? Yet NOAA has ...
