Based on the straight pipe case, a perturbative analysis by which the boundary value conditions are exactly satisfied is employed. As such an analysis, we decompose the wave equation into a set of ordinary differential equations perturbatively. We show the conditions when secular terms due to the...
of seismic wavefield directly.The formula transformation from common-shot domain to common midpoint(CMP) domain was achieved according to the theory of wavefield double downward continuation in prestack depth migration.Then the preserved-amplitude one-way wave equation defined by double-square-root ...
A wave is represented by the equation A、Frequency= B、Amplitude=0.001mm C、MaximumVelocity of the Particle 60 mm/sec D、wavevelocity is 100m/s
First of all, the amplitude of a wave has nothing to do with its wavelength or its period. Basically here we only have the wavelength so it is... See full answer below.Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a qu...

We obtain a system of integral equations for the spinor amplitude of a wave packet describing a massive neutral Dirac particle in a curved space–time with an arbitrary geometry. This equation permits describing the spin dynamics of fermions in gravitational fields adequately to the quantum nature ...

Then, the equation of Amplitude Modulated wave will bes(t)=[Ac+Amcos(2πfmt)]cos(2πfct)s(t)=[Ac+Amcos(2πfmt)]cos(2πfct) (Equation 1)Modulation IndexA carrier wave, after being modulated, if the modulated level is calculated, then such an attempt is called as ...
Carotid-femoral pulse wave velocity (cfPWV), augmentation index (AIx), amplitude of forward wave (Pf), and backward wave (Pb) were described in different age categories for both sexes. Sex-specific reference equations for cfPWV, AIx, Pf, and Pb with age as the predictive variable were ...
