It can penetrate up to 15 inches (38 cm) of metal or 11 ft (3.4 m) of concrete, depending on the height from which it is dropped, and causes lethal fragmentation to a radius of 400 yards (370 m). Many Mark 84s have been retrofitted with stabilizing and retarding devices to provide precision guidance capabilities.
A Rao–Blackwell estimator δ 1 (X) of an unobservable quantity θ is the conditional expected value E(δ(X) | T(X)) of some estimator δ(X) given a sufficient statistic T(X). Call δ(X) the "original estimator" and δ 1 (X) the "improved estimator". It is important that the improved estimator be observable, i.e. that it
Rakon Limited is a technology company founded in 1967 that designs and manufactures frequency control products, primarily quartz crystals and temperature-compensated crystal oscillators ( TCXO ), [1] oven controlled crystal oscillators ( OCXO) and voltage controlled crystal oscillators ( VCXO ). [2] Its head office is in Auckland, New Zealand ...
A cost estimate is the approximation of the cost of a program, project, or operation. The cost estimate is the product of the cost estimating process. The cost estimate has a single total value and may have identifiable component values. A problem with a cost overrun can be avoided with a credible, reliable, and accurate cost estimate.
The mirror has a polished area of 26.3 m 2 (283 sq ft), of which 0.9 m 2 (9.7 sq ft) is obscured by the secondary support struts, giving a total collecting area of 25.4 m 2 (273 sq ft). This is over six times larger than the collecting area of Hubble's 2.4 m (7.9 ft) diameter mirror, which has a collecting area of 4.0 m 2 (43 sq
Time-resolved simulation of a pulse reflecting from a Bragg mirror. A distributed Bragg reflector (DBR) is a reflector used in waveguides, such as optical fibers.It is a structure formed from multiple layers of alternating materials with different refractive index, or by periodic variation of some characteristic (such as height) of a dielectric waveguide, resulting in periodic variation in the ...
The geometric series on the real line. In mathematics, the infinite series 1 2 + 1 4 + 1 8 + 1 16 + ··· is an elementary example of a geometric series that converges absolutely. The sum of the series is 1. In summation notation, this may be expressed as. The series is related to philosophical questions considered in antiquity, particularly ...
