Waves generated by collisions of solitary waves

Physical Review A, 1987
The small-amplitude, long-wavelength perturbation expansion of the water-wave equation has been extended to the fourth order of approximation for overtaking collisions of solitary waves. It is found that collisions of solitary waves generate, besides the dispersive wave train reported by us earlier [Q.-s. Zou and C.-H. Su, Phys. Fluids 20, 2113 (1986)],

Lambda Waves and Occipital Generators

Clinical EEG and Neuroscience, 2013
The objective of this study was to identify the relationship between lambda waves (LWs) and other occipital waveforms, in a retrospective analysis of electroencephalograms (EEGs) of clinic and hospitalized patients at a single center. The LWs were correlated with α rhythm, photic driving, and positive occipital sharp transients of sleep (POSTS).

Waves generated by an inclined‐plate wave generator

International Journal for Numerical Methods in Fluids, 1988
AbstractThis paper describes the characteristics of small‐amplitude waves generated by a sinusoidally oscillating, inclined paddle‐type wavemaker operating in a constant‐depth channel. Two‐dimensional, linearized potential flow is assumed. A semi‐analytical method, the boundary collocation method, is used to establish the relationship between wave ...

Harmonic Generation in an Electromagnetic Wave

ZAMP Zeitschrift für angewandte Mathematik und Physik, 1973
A plane electromagnetic wave is propagated in a non-linear non-dissipative isotropic dielectric. A method is given for the calculation of the change in the amplitudes and phases of harmonics of all orders, as the wave progresses, for any specified dependence of the dielectric constant on the magnitude of the electric field and for any initial wave form.

The Generation of a Tollmien-Schlichting Wave by a Sound Wave

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1980
Abstract A spectral numerical method is used to study the two-dimensional unsteady flow over a flat plate in the presence of a plane sound wave propagating parallel to the flow. For s = ωx/U∞ > O(1), no observable interaction or energy interchange between the sound wave and the Tollmien-Schlichting wave is present.
