Dispersion

In statistics, the placement of data points along a chart relative to an average or mean line. Dispersion is important to finance as the data points of say, a stock, determine the mean, which in turn helps determines the stock's trend. Dispersion is also used to determine volatility: data points all over the chart indicate that a stock has wild fluctuation in price.

UV-Vis spectroscopy of all these dispersions were undertaken to see the dispersion capability of these solvents.
Figure 5 shows a comparative study giving the dispersion properties with and without the liquid with the optimized PCF design.
To achieve the dispersion near +4.5 ps/km/nm we have increased the value of parameter a of near-zero dispersion flattened fiber to 2.5 [micro]m and all other parameters are kept same.
1, peaks 2 and 3 from the left), and the dispersion becomes unstable.
Saffman (1959) developed a model for the dispersion of tracer in a network of randomly orientated straight pores of circular section by considering a random walk of a tracer particle.
Note that the pigment is flocculated at all but the very lowest thickener concentrations, and that the dispersant had little effect on the dispersion state.
The concentration measurements indicated that significant reduction in the dispersion effectiveness of CF3I occurred when it was used at temperatures below its normal boiling.
In the dispersion phase (Figure 2), mechanical energy is used to break up chunks, clumps, and clusters.
For the purpose of analysis of the dispersion data for SAWs, NIST developed a computationally efficient representation of the Green's function to model the elastodynamic characteristics of an anisotropic thin film on an anisotropic substrate.
Here are ways to improve each step of the dispersion process.
One of the most intricate parts of the dispersion process is the milling and grinding of agglomerates of pigments to separate them so that they can be reduced to microscopic-sized primary particles which must be stabilized to prevent them coming together again.
For FEVE emulsions and the dispersion, the mill-base was prepared by dispersing [TiO.sub.2] pigment (Ti-Pure R-706) in water along with a dispersant and a de-foamer.
