The MOS is measured on a scale of one to five, although 4.4 is technically the highest score possible on a VoIP network [source: TestYourVoIP.com]. An MOS of 3.5 or above is considered a "good call" [source: ManageEngine]. To come up with the MOS, call monitoring hardware and ...
The "strength" of a rocket engine is called its thrust. Thrust is measured in "pounds of thrust" in the U.S. and in Newtons under the metric system (4.45 Newtons of thrust equals 1 pound of thrust). A pound of thrust is the amount of thrust it would take to keep a 1-pound objec...
The wavelength of light is the distance from one peak of the wave to the next. This relates to the wave's frequency, or the number of waves that pass a point in a given period of time. The frequency of light determines its color and is measured in cycles per second, or Hertz (Hz)...

How far is far? 来自 IEEEXplore 喜欢 0 阅读量: 151 作者:E.F. Knott,T.B.A. Senior 摘要: Recent comparisons of computed and measured backscattering cross sections of cylindrical bodies revealed unexpectedly large discrepancies which were apparently due to the finite range used in the measurements...
The radical scavenging activity was measured for each specimen as percentage inhibition of DPPH = (1 − As/Ac)× 100, where As stands for sample absorbance and Ac for negative control. The IC50± SD (µg/mL) values were then calculated, representing the percentage required by the samples...
According to [53], competition includes rivalry between cities that is measured by other cities. According to [54], urban landscape competitiveness is a relative value rather than an absolute quantity. The entropy weight method is a straightforward way to determine the relative weight in multiobject...

[Note: All in all, the differences in stated length and measured length via a straight-tape measurement are typically within 1-3 cm, which is quite small; the other sections here are typically much more important to consider when thinking about how long various skis feel on snow. But, it...
