acoustic wave analysis
1Acoustic theory — is the field relating to mathematical description of sound waves. It is derived from fluid dynamics. See acoustics for the engineering approach.The propagation of sound waves in a fluid (such as air) can be modeled by an equation of motion… …
2Acoustic Radiation Force Impulse (ARFI) Imaging — uses acoustic radiation force to generate images of the mechanical properties of soft tissue. How it worksAcoustic radiation force is a phenomenon associated with the propagation of acoustic waves in attenuating media. Attenuation includes both… …
3Acoustic microscopy — Introduction = Acoustic microscopes employ very high or ultra high frequency ultrasound. These microscopes operate nondestructively and penetrate most solid materials to make visible images of internal features, including defects such as cracks,… …
4Acoustic rheometer — employes piezo electric crystal that can easily launch a successive wave of extensions and contractions into the fluid. It applies an oscillating extensional stress to the system. System response can be interpreted in terms of extensional… …

6Time-frequency analysis — is a body of techniques for characterizing and manipulating signals whose component frequencies vary in time, such as transient signals.Whereas the technique of the Fourier transform can be used to obtain the frequency spectrum of a signal whose… …
7Electro Magnetic Acoustic Transducer — An Electro Magnetic Acoustic Transducer (EMAT), is a non contact inspection device that generates an ultrasonic pulse in the part or sample inspected, instead of the transducer. The waves reflected by the sample induce a varying electric current… …
8Wind wave model — NOAA Wavewatch III 120 hour Forecast for the North Atlantic In fluid dynamics, wind wave modeling describes the effort to depict the sea state and predict the evolution of the energy of wind waves using numerical techniques. These simulations… …
9Cnoidal wave — US Army bombers flying over near periodic swell in shallow water, close to the Panama coast (1933). The sharp crests and very flat troughs are characteristic for cnoidal waves. In fluid dynamics, a cnoidal wave is a nonlinear and exact periodic… …
