wave equation n (General Physics) physics a partial differential equation describing wave motion. It has the form ∇2φ = (1/c2)× (∂2φ/∂t2), where ∇2 is the Laplace operator, t the time, c the speed of propagation, and φ is a function characterizing the displacement of...
wave speedminimax representationestimates35K57A nonlocal reaction-diffusion equation arising in various applications is studied. The speed of travelling waves is determined by means of a minimax representation. It is used to obtain the wave speed estimates and asymptotic values....
Eventually, the dynamics is governed by an equation analogous to that of a pendulum, in which the center of mass of the soliton is subjected to a periodic potential. Consequently, the soliton speed is not constant and generally contains a periodic component. Furthermore, the interaction between ...
Speed = Wavelength • Frequency The above equation is known as the wave equation. It states the mathematical relationship between the speed (v) of a wave and its wavelength (λ) and frequency (f). Using the symbols v,λ, and f, the equation can be rewritten as v = f • λ As ...

This allowed the construction of a speed-frequency chart for each tissue sample. In the next section will be represented the mean and standard deviation of the shear wave speeds using data from all the tissue samples. The high differences on the frequency ranges of the two techniques should be...
Their results show that the high-resolution wind forcing, as well as the generated wave field, have a dependence on the radius of maximum wind and the cyclone’s translation speed. When the translation speed is low, the wave direction is determined by the distance to the center of the ...
