Velocity-modulation control of electron-wave propagation in graphene

A Study of the Wave Propagation Velocity in Granular Soils Using Discrete Element Method (DEM)

In the present paper, discrete element method (DEM) is used to study wave propagation phenomenon in granular soils. The effect of factors such as coefficient of friction, frequency, normal stiffness and soil gradation on the wave velocity is studied. Using the wall motion based on the sinusoidal function is the method of loading used in this simulation, through which the pressure wave is transf...

Nonlinear wave propagation in free-electron lasers.

Wave propagation theory in offshore applications

A frequency-wavenumber-domain formulation is presented in this paper for calculation of the Green's functions and wave propagation modes in a stratified fluid body underlain by a layered viscoelastic soil medium. The Green's functions define the solid and fluid displacements and fluid pressures due to uniform disk loads acting in either the soil or fluid media. The solution is in the frequency ...

Wave Propagation in Micropolar Thermoelastic Diffusion Medium

The present investigation is concerned with the reflection of plane waves from a free surface of a micropolar thermoelastic diffusion half space in the context of coupled theory of thermoelastic diffusion. The amplitude ratios of various reflected waves are obtained in a closed form. The dependence of these amplitude ratios with an angle of propagation as well as other material parameter are sh...

Errors in estimating propagation distances in pulse wave velocity.

Errors in Estimating Propagation Distances in Pulse Wave Velocity To the Editor: Recent correspondence1,2 over the report by Lantelme et al3 exposes a more serious problem with the use of the automated pulse wave velocity (PWV) measuring instrument (Complior®). The aortic PWV reported by Lantelme et al ( 14 m/s) was approximately 50% higher than the aortic PWVs obtained by others for similarly ...
