A description of the vertical structure and the phase speed of long linear internal waves c can be found (in the Boussinesq approximation) from the following Sturm-Liouville problem:

The first mode corresponds to the case when the mode function [PHI](z) does not vanish within the interval [0, H] and the phase speed c is the largest eigenvalue of the Sturm-Liouville problem (3), (4).

Seasonal changes in so-called linear parameters of internal wave propagation--the phase speed c (Fig.

These characteristics are similar to those discussed by Karpman [11] as 'soliton radiation', in which a soliton emits dispersive waves whose phase speed is equal to that of the soliton.

The observed phase speed of the upstream waves is equal to the speed of the solitary wave, in agreement with the soliton radiation theory.

where A is the area of impact, K is an empirical constant between 3 and 10, [rho] is the water density and C is the wave phase speed.

The acceleration increases as a function of the wave height (h), length of the arms (D) and the phase speed (C).

Effective electron beam-wave interaction for amplification purpose is only possible in the constant phase speed region of the first 'allowed region'.

The calculated phase speed of these waves is about 10-13 cm/s and according to the theoretical distribution of amplitudes, they exist in the near-shore region up to 15-20 km from the coastline.

A pair of hydrophones or transducers is used to transmit and receive a series of short monochromatic bursts of varying frequencies from which the attenuation and phase speed in the bubbly liquid are determined.

Structure change in the process of a pulling should obviously lead to some mismatch of phase speeds of waves interacting in PPLN, to compensation of the induced wave unbalancing (at the constant period of a domain grid), and as a result of temperature influence to the leveling of own crystal matrix absorption.

Since the curve of a phase speeds mismatch in PPLN has not only temperature dependence, but also dependence on structure of a crystal which forms PPLN structure, due to dependence of n([lambda],T,[C.
