slender body; Sub-carangiform, in which the wave increases quickly in amplitude towards the tail; Carangiform, in which the wave is concentrated near...

in different locations around the world. The wave often occurs as an amplitude-ordered series of waves forming bands of roll clouds. The southern part...

classical algorithms, however. Grover's algorithm, along with variants like amplitude amplification, can be used to speed up a broad range of algorithms. In...

antiresonance, by analogy with resonance, is a pronounced minimum in the amplitude of an oscillator at a particular frequency, accompanied by a large, abrupt...

brightness by astronomer P. M. Corben in 1971. It was said to have an amplitude of 0.18 magnitudes. A year later, HD 33684 was given the variable star...

the scattering amplitude as a function of the cosine of the scattering angle as the power law for the falloff of scattering amplitudes at high energy...

antimode. The difference between the major and minor modes is known as the amplitude. In time series the major mode is called the acrophase and the antimode...

unaffected, until translated into a vehicle yaw oscillation of increasing amplitude, producing loss of control. Vehicles that can experience this oscillation...

identities which impose the symmetry on the level of the quantum mechanical amplitudes. This generalized sense should be distinguished when reading literature...

star with a mean apparent magnitude of +3.93, and a variable star of low amplitude. The radial velocity of V382 Carinae has long been known to be variable...

wavefront becomes the source of a secondary spherical wavelet and that the amplitude of the optical field E at a point on the screen is given by the superposition...

same as acousto-optic modulators (AOMs). In both an AOM and an AOD, the amplitude and frequency of different orders are adjusted as light is diffracted...

spinning at 30 times the rate of synchronous rotation. In 1991, the eclipse amplitude was found to have changed multiple times, declining from a magnitude difference...

IRAC. A relative small amplitude of 4–5% was measured. Water ice cloud models predicted a large amplitude. This small amplitude might suggest that the...
