Search Results for "sound wave propagation"

The WSJT project implements software for amateur radio communication using state-of-the-art digital techniques. Typical applications involve "DXing" at LF, MF, HF, and VHF+ frequencies, including meteor scatter and EME ("moonbounce"). Major emphasis is placed on weak-signal techniques. Summary Program Descriptions: WSJT-X supports the communication protocols FST4, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, WSPR, FST4W, and Echo, each optimized for different sorts of radio-wave propagation...

A spectral element method for 2D wave propagation and fracture dynamics, with emphasis on computational seismology and earthquake source dynamics.

Sound Propagation and Acoustic Radiation of Turbomachines - Aeroacoustic Noise Suppression Project : A CFD-like CAA code for predicting turbomachines noise.

A solver based on the spectral element method, used in conjunction with FEMAP, as a pre- and post- processor. It solves the elastic wave propagation problem, and the coupling with a piezoelectric materials for excitation and sensing. It is currently in 2D and has both static and transient capabilities.
