Physical possibilities of remote diagnostics and manipulation with the state of the propagation medium by the methods of wave tomosynthesis are considered. This refers to the electromagnetic and acoustic waves as well as waves of other nature. Important are multi-position measurements with retention of phase information at each point of the medium that

TRAVELLING WAVES FOR FORCED FISHER'S EQUATION
Nonlinear Analysis: Theory, Methods & Applications, 1986The author studies travelling waves (the solutions of the form \(u(x,t)=U(x-ct))\) for Fisher's equations \[ u_ t=u_{xx}+f(u),\quad u_ t=u_{xx}+f(u)+\mu g(x-ct), \] where \(\mu\) is a small parameter, f twice continuously differentiable and \(f(0)=f(1)=0,\quad f'(0)\neq 0>f'(1).\) Two cases of functions f are considered: (i) \(f(u)>0\) for ...

The present paper investigates the application of boundary element methods [1] [2] to compute wave forces on fixed and floating offshore structures of arbitrary shapes. Although the present work deals only with two dimensional applications, a similar theory can be applied to three-dimensional problems [3] Results are then compared against the ...

Reviews of Geophysics, 1978
This paper concerns the linear response of the ocean to forcing at a specified frequency and wave number in the absence of mean currents. It discusses the details of the forcing function, the general properties of the equations of motion, and possible simplifications of these equations.

Journal of Waterway, Port, Coastal, and Ocean Engineering, 1991
Revised criteria is presented for wave shoaling after breaking on a plane beach and for resulting wave forces on a wall landward of the still-water line. Existing criteria is based on the assumption that the wave height above still water will remain constant between the point of wave breaking and the shoreline.

Probabilistic descriptors are developed for Morison‐type wave forces. They are based on the actual distribution of these forces and on the hypothesis that wave forces follow Gaussian distributions. The Gaussian hypothesis is characteristic of analyses based on statistical linearization.

Quasi‐geostrophic planetary wave forcing
Quarterly Journal of the Royal Meteorological Society, 1978AbstractThe problem of stationary planetary wave forcing by orography and longitudinal asymmetry of heating is re‐examined in the light of recent observations and theories of stratospheric motion. It is deduced that the region between 30 and 60km is a sink of planetary wave energy for zonal wavenumbers one and two in winter and that, in contrast to ...
