effective radius

[ə¦fek·tiv ′rād·ē·əs]
(astronomy)
The distance from the center of an external galaxy within which half its luminosity is included.
(ordnance)
The radius of a circle having its center at the center of impact of a nuclear weapon, and within which a specified dosage of radiation is equaled or exceeded within a given period of time.

The theoretic effective radius of this rifle is three hundred miles, but the best they can do in actual service when equipped with their wireless finders and sighters is but a trifle over two hundred miles.
Previous work has shown that the cloud-top reflectance in the near-infrared increases in middle-latitude, deep-convective overshooting tops--the overshooting tops appear lighter than the surrounding glaciated clouds due to smaller ice crystals (2-4 [micro]m in effective radius), which are frozen nearly instantaneously in intense thunderstorm updrafts.
With an effective radius of 0.56 km, 46P's nucleus is modestly sized.
Increased the radius of explosion effect considering the actual effective radius
Determination of effective radius is very important for obtaining the effective cutting speed.
The effective radius and effective variance are [r.sub.e] = ([alpha] + 3)/[beta] and [v.sub.e] = 1/([alpha] + 3), respectively.
In the big bang theory, the ratio between the effective radius and the radius of the universe increases as the universe expands and will reach the unity at a point, which is the present time if the universe has mass [M.sub.0].
r corresponds to the effective radius which can be calculated by subtracting deposit thickness from tube inner radius.
the number of balls (z), the curvature sum (R), the equivalent elastic modulus (E), the effective radius ratio ([gamma]), the friction force, and the load.
With its effective radius of 30 feet, a single Cota charging station can simultaneously charge or power all the battery-operated devices in every room of an average home or office suite.
Usually the density may be lower; therefore, we shall define the effective radius [r.sub.eff] of the capillary dependent on the microvilli density p and their other parameters as follows:
The output data consists in approximations of particle volume size distributions which are used to compute particle effective radius ([R.sub.eff]), surface area (S), and volume concentrations (V) as well as the complex refractive index (CRI) and single scattering albedo (SSA).
