Sentences with phrase «small amplitude»

Large fluctuations in lower density parts of the Universe have an effect similar to that of smaller amplitude fluctuations in denser regions and the two can not be distinguished by observations of weak lensing.

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).

For example, analytic solutions of «linear» differential equations that describe simple harmonic motions are only found in dynamical systems with small amplitudes, where non - linear terms are assumed to be negligible.

«But we know that even at the quantum ground state, at zero - temperature, very small amplitude fluctuations — or noise — remain.»

Our notes described the ride as «cushy», except at very low speeds, where small amplitude bumps were quite noticeable.

Second, sub-stage 19c lies near the middle - Pleistocene, a time when the climate system appears to have been most clearly transitioning from smaller amplitude, shorter period, and more symmetric glacial cycles, to the larger, longer, and more saw - toothed glacial cycles of the late Pleistocene.

Until now, experiments could only obtain such superpositions at small amplitudes that limited their use.

Prior to the onset of a nearly monotone booming, burps of sound of smaller amplitude occur over a significantly broader span of frequencies.

This novel experimental scheme is highly sensitive and allows for the first time to kick off and detect extremely small amplitudes of atomic vibrations.

It is also a suspected small amplitude variable star.

Large washouts pose little threat to the car's composure — the small exception being some busyness over minor small amplitude imperfections.

Similarly, a large amplitude, slow frequency cat - like tail swish means the dog reeeeally doesn't like you and a high frequency, small amplitude vibration at the tip of the dog's perpendicularly held tail, generally signals the animal is extremely tense and stressed and about to react.

These considerations apply to the growth phase of small amplitude eddies.

Assuming small amplitude waves and scale separation and that the dynamics of barotropic storm tracks dominate the problem, Doppler correction would not be necessary.

Imagine their surprise when they see that the ensemble averages you publish have much smaller amplitude.»

A solar component July — August 2017 Handled by Vincent Courtillot «''... we uncover two more components, with smaller amplitude than the three first ones, but well identified, periodic with periods of 11 and 5.5 years, respectively, undoubtedly linked to solar activity.

«We were wondering: how could it happen that a very tiny wave with a very small amplitude could trigger earthquakes a thousand kilometres away?»

These strategies typically involve generating additional waves of smaller amplitude (additional, smaller steps, for example) or attempts to increase the width (duration) of the pulse at the expense of pulse amplitude by using a tapered section to extend the area change over a longer period of time.

It seems that the different disturbances lead mainly to a small amplitude noise that blurs the underlying periodic signal.»

Eclipsing variables of this type may develop into eruptive «dwarf novae» similar to U Geminorum and SS Cygni, and U Pegasi has been observed to exhibit flares or eruptions of small amplitude that may presage more violent activity at a later stage of evolution.

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.

If the length of BNO (R) cycle shortens while the amplitude of the forcing remains constant, it will result in a smaller amplitude of the temperature response, and if the cycle lengthens it will increase in amplitude of the temperature wobble.

In the Northern Hemisphere, the trend agrees in sign but is of smaller amplitude than that observed during recent decades.
