Basic experimental study of the coupling between flow instabilities and incident sound... Instability waves in the shear layer of a subsonic jet, excited by a point sound source located external to the jet, were first visualized using an ensemble averaging technique....
Using addition theorem and superposition technique yi-jhou lin1*, ying-te lee1, i-lin chen2 and jeng-tzong chen1,3In this paper, we employ the addition theorem and superposition technique to solve the scattering problem with multiple circular cylinders arising from a point sound source....
Interactive viewpoint-space navigation for visual-audio exhibition of painting... There are three parts in our system: (1) we allocate a voice dubbing or background music, which is treated as a point sound source, onto the 2D painting and obtain its position in the 2D space....
Numerical calculation of seafloor synthetic seismograms caused by low frequency point sound source ... In order to analyze the wave components and the propagating properties of ship seismic wave, the numerical calculation of synthetic seismograms on seafloor aroused by a low frequency point sound source is carried out using a wave number integration technique combined with inverse Fourier transform....
