Prentice's rule, named so after the optician Charles F. Prentice, is a formula used to determine the amount of induced prism in a lens: = where: P is the amount of prism correction (in prism dioptres) c is decentration (the distance between the pupil centre and the lens's optical centre, in millimetres)
In nuclear physics, the internal conversion coefficient describes the rate of internal conversion. The internal conversion coefficient may be empirically determined by the following formula:
Šidák correction for t-test. One of the application of Student's t-test is to test the location of one sequence of independent and identically distributed random variables.
A direct formula for the conversion from a quaternion to Euler angles in any of the 12 possible sequences exists. [2] For the rest of this section, the formula for the sequence Body 3-2-1 will be shown. If the quaternion is properly normalized, the Euler angles can be obtained from the quaternions via the relations:
The formula for decay correcting is: [1] where is the original activity count at time zero, is the activity at time "t", "λ" is the decay constant, and "t" is the elapsed time. The decay constant is where " " is the half-life of the radioactive material of interest.
Conversion to dose rate. Count rate does not universally equate to dose rate, and there is no simple universal conversion factor. Any conversions are instrument-specific. Counts is the number of events detected, but dose rate relates to the amount of ionising energy deposited in the sensor of the radiation detector. The conversion calculation ...
Bolometric correction is the correction made to the absolute magnitude of an object in order to convert an object's visible magnitude to its bolometric magnitude. Alternatively, the bolometric correction can be made to absolute magnitudes based on other wavelength bands beyond the visible electromagnetic spectrum. [4]
The mathematical derivation for the Eötvös effect for motion along the Equator explains the factor 2 in the first term of the Eötvös correction formula. What remains to be explained is the cosine factor.
The error analysis for the Global Positioning System is important for understanding how GPS works, and for knowing what magnitude of error should be expected. The GPS makes corrections for receiver clock errors and other effects but there are still residual errors which are not corrected.
In animal husbandry, feed conversion ratio ( FCR) or feed conversion rate is a ratio or rate measuring of the efficiency with which the bodies of livestock convert animal feed into the desired output. For dairy cows, for example, the output is milk, whereas in animals raised for meat (such as beef cows, [1] pigs, chickens, and fish) the output ...
