Miller twist rule is a mathematical formula derived by American physical chemist and historian of science Donald G. Miller (1927-2012) to determine the rate of twist to apply to a given bullet to provide optimum stability using a rifled barrel. [1]
Spread Component (SC) (as used in the National Fire Danger Rating System) is a rating of the forward rate of spread of a headfire. [1] Deeming states that "the spread component is numerically equal to the theoretical ideal rate of spread expressed in feet-per-minute."
SC is the spread component, and ERC is the Energy Release Component. Consequently, the equation for the Burning Index is: [1] = where is the Burning Index scaling factor of (10/ft). Therefore, dividing the Burning Index by 10 produces a reasonable estimate of the flame length at the head of a fire.

The evolution of college sports into a more professionalized entity may soon take another step: jersey patches. While jersey patches are still prohibited under NCAA rules, college leaders have ...
If the symbol duration is long enough compared to the delay spread (typically 10 times as big would be good enough), one can expect an equivalent ISI-free channel. The correspondence with the frequency domain is the notion of coherence bandwidth (CB), which is the bandwidth over which the channel can be assumed flat (i.e. channel that passes ...
