Acoustics in the Klebanoff-Saric Wind Tunnel: Background Identification, Forcing, and Active Control (2012-07-16)Low disturbance wind tunnels, such as the Klebanoff–Saric Wind Tunnel (KSWT), offer an ideal environment to study boundary layer transition. In particular, the leading-edge receptivity of sound can be measured by creating ...

(2020-09-11)Passive acoustic monitoring is an effective tool for delineating population structure of blue whales (Balaenoptera musculus). Globally, there are at least nine regionally distinct blue whale songs, with two to three distinct ...
-
(2014-05-06)In recent years, research has shown that the educational environment has a profound effect on learning and performance among students, especially those with autism. Many design solutions that target autistic populations ...
