SF is determined by measuring the difference between two threshold measurements at 10 different points across the entire field during the same test.
By measuring the difference between 0th-order and 1st-order diffraction efficiencies, the measurement sensitivity is improved, while common mode laser source noise is eliminated.
This is as good a way as any, I suppose, of measuring the difference between real imagination and mere phant'sy.
Finally, salt marsh impacts were estimated by measuring the difference in annual loss costs between properties with and without marshes.
The result of the t-test measuring the difference between them is statistically significant (p = 0.0207).
Smart phones currently have fingerprint sensors, based on measuring the difference in capacitance between air and human tissue.
A technique that measures the rotational diffusion of fluorophores by measuring the difference in the polarization of excitation and emission light.
Here, the phase encoded signal interferes with a local oscillator and is detected by a balanced detector measuring the difference signal of two equal photodiodes.
We determined the contribution of peatlands to bird regional diversity by measuring the difference between peatland and associated regional avifaunas.
The unknown parameters are estimated by minimizing a cost function measuring the difference between experimental and simulated concentration profiles.
It is used to quantify vegetation by measuring the difference between near-infrared (which vegetation strongly reflects) and red light (which vegetation absorbs).
