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.

"We couldn't be prouder to receive recognition for our continued efforts and commitment to grow the company in such a prestigious way", says Keith Malone, commercial manager, Diamond Dispersions. "The Queen's Award is an honor that is admired across the globe, not just in the UK - and it deeply matters to every one of us at Diamond Dispersions."
The dispersions can maintain their distribution and state of dispersion during addition to latex formulations and during the drying process of a coating, when polymers begin to coalesce and entangle.

While the five-year figures above are eye-opening, this dispersion anomaly is exacerbated when looking at the extremes, shorter time periods and institutional hedge fund managers.
FiberStore dispersion compensation modules are used in optical networks to reduce the accumulated dispersion in optical signals carrying information.
Pressure, temperature and humidity all affect the amount of dispersion that will occur for a given altitude but, for the typical amateur observer, these secondary effects are very small.
A change in dispersion stability can be caused by many processes which manifest themselves by a change in particle size and thus by a change in viscosity and in sedimentation velocity (Loria et al.

Waveguide dispersion is caused by physical structure of optical fiber core and cladding (refractive index profile), and as a result different wavelengths propagate at different velocities in the core and cladding.
