  2. Conversion of scales of temperature - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_scales_of...

    This is a collection of temperature conversion formulas and comparisons among eight different temperature scales, several of which have long been obsolete.. Temperatures on scales that either do not share a numeric zero or are nonlinearly related cannot correctly be mathematically equated (related using the symbol =), and thus temperatures on different scales are more correctly described as ...

  3. EWMA chart - Wikipedia

    en.wikipedia.org/wiki/EWMA_chart

    The EWMA chart is sensitive to small shifts in the process mean, but does not match the ability of Shewhart-style charts (namely the ¯ and R and ¯ and s charts) to detect larger shifts. [ 2 ] : 412 One author recommends superimposing the EWMA chart on top of a suitable Shewhart-style chart with widened control limits in order to detect both ...

  4. Bethe formula - Wikipedia

    en.wikipedia.org/wiki/Bethe_formula

    If this approximation is introduced into formula above, one obtains an expression which is often called Bethe-Bloch formula. But since we have now accurate tables of I as a function of Z (see below), the use of such a table will yield better results than the use of formula . The figure shows normalized values of I, taken from a table. [5]

  5. Gamma correction - Wikipedia

    en.wikipedia.org/wiki/Gamma_correction

    Gamma correction or gamma is a nonlinear operation used to encode and decode luminance or tristimulus values in video or still image systems. [1] Gamma correction is, in the simplest cases, defined by the following power-law expression: =,

  6. Volume correction factor - Wikipedia

    en.wikipedia.org/wiki/Volume_Correction_Factor

    In thermodynamics, the Volume Correction Factor (VCF), also known as Correction for the effect of Temperature on Liquid (CTL), is a standardized computed factor used to correct for the thermal expansion of fluids, primarily, liquid hydrocarbons at various temperatures and densities. [1]

  7. List of optics equations - Wikipedia

    en.wikipedia.org/wiki/List_of_optics_equations

    Visulization of flux through differential area and solid angle. As always ^ is the unit normal to the incident surface A, = ^, and ^ is a unit vector in the direction of incident flux on the area element, θ is the angle between them.

  8. Euler's formula - Wikipedia

    en.wikipedia.org/wiki/Euler's_formula

    The formula is still valid if x is a complex number, and is also called Euler's formula in this more general case. [1] Euler's formula is ubiquitous in mathematics, physics, chemistry, and engineering. The physicist Richard Feynman called the equation "our jewel" and "the most remarkable formula in mathematics". [2]

  9. Fission barrier - Wikipedia

    en.wikipedia.org/wiki/Fission_Barrier

    Soviet physicist Vilen Strutinsky proposed such a method using "shell correction" and corrections for nuclear pairing to the liquid drop model. [5] In this method, the total energy of the nucleus is taken as the sum of the liquid drop model energy, E L D M {\displaystyle E_{LDM}} , the shell, δ S {\displaystyle \delta S} , and pairing, δ P ...
