Sentences with phrase «small amplitude waves»

Another highly idealized theory is a barotropic storm track which for small amplitude waves can be approximated by WKB theory (Lee 1995; Swanson et al. 1997).

It assumes a scale separation between a barotropic background flow and a small amplitude wave and predicts a change of k with the flow so that wave activity is conserved.

Not exact matches

In many versions of the theory, the amplitude of the gravitational waves is miserably small, so they would not be detectable.

In an explosion as compared with an earthquake, the amplitudes of Rayleigh waves are smaller than those of the P waves.

This term expresses the fact that the initial sphericity of the supernova shock wave is spontaneously broken, because the shock develops large - amplitude, pulsating asymmetries by the oscillatory growth of initially small, random seed perturbations.

Researchers have now built a working tractor beam that uses high - amplitude sound waves to generate an acoustic hologram which can pick up and move small objects.

The dentate gyrus also generates theta waves, which are difficult to separate from the CA1 waves because they are considerably smaller in amplitude, but there is some evidence that dentate gyrus theta is usually about 90 degrees out of phase from CA1 theta.

TERRENCE HOWARD: A solid tone; a true element is one that is able to reach the wave amplitude, but after the fifth octave, all elements carbon is no longer able to reach its full amplitude and so it breaks down into small things called isotopes.

Here I looked at the very long wave that seem to be present., almost like a wave 600 years long of small amplitude, but still present.

There it is shown that small - amplitude vacuum density waves generated by the motion of the supermassive objects located in the center of the Galaxy are constantly acting on the Sun and the Earth and are thereby producing a series of physical reactions within these celestial bodies.

Regarding your example of water in a tub, you in fact assume that amplitude of waves is much smaller than the overall water level, so you have a small parameter here, and some sort of perturbation method might be used to derive a reasonable model for the averaged level in the tub.

Looking at the amplitude the AMO could have conceivably contributed to global warming, perhaps one fiftieth to one thirtieth of the total, we are very far away from having to consider this, or any of the even smaller parts of the stadium wave, significant.
