Congruence of data to normal dispersion was evaluated using Kolmogorov-Smirnov Z test.
The role of the normal dispersion in SC of subpicosecond laser pulses is analyzed in [8].
It was demonstrated that the DW emission is no longer thought to be the exclusive of solitons because the dispersive wave can be emitted even when pumping in the normal dispersion regime in the presence of a zero GVD wavelength [21].
The negative value of the parameter P creates a reversed Airy-like pulse (oscillatory tail in front of the pulse) in case of normal dispersion. In case of the positive value of P a soliton train emerges and the velocity and the amplitude of the leading soliton and the number of solitons are directly related to the value of the nonlinear parameter P.
Dielectric constant and tangent loss showed normal dispersion behavior.
Some our offered mathematical models of the delay line demonstrated at low frequencies not only abnormal but normal dispersion also.
There is anomalous dispersion regions when 2.25 < E <2.95 eV and E > 4.85 eV, as well as normal dispersion when 2.95 < < 3.45 eV for doped samples.
The second segment is channel waveguide with width of [W.sub.2], which has a normal dispersion at the pump wavelength.
Two DW peaks centered in the normal dispersion region can be used as the pump and Stokes pulses for the high resolution CARS microscopy.

From 465 observations the measurements result of the slag compound, for annually production, it's observed that is existing one pronounced variation of value of slag components and this variation is of not determinate character with normal dispersion ore lognormal.
