  2. Faxén's law - Wikipedia

    en.wikipedia.org/wiki/Faxén's_law

    Faxén's law is a correction to Stokes' law for the friction on spherical objects in a viscous fluid, valid where the object moves close to a wall of the container. [4]

  3. Free-air gravity anomaly - Wikipedia

    en.wikipedia.org/wiki/Free-air_gravity_anomaly

    Gravity is computed on the ellipsoid surface using the International Gravity Formula. For studies of subsurface structure, the free-air anomaly is further adjusted by a correction for the mass below the measurement point and above the reference of mean sea level or a local datum elevation. [3] This defines the Bouguer anomaly.

  4. Statistical process control - Wikipedia

    en.wikipedia.org/wiki/Statistical_process_control

    Control charts attempt to differentiate "assignable" ("special") sources of variation from "common" sources. "Common" sources, because they are an expected part of the process, are of much less concern to the manufacturer than "assignable" sources. Using control charts is a continuous activity, ongoing over time.

  5. Smith chart - Wikipedia

    en.wikipedia.org/wiki/Smith_chart

    The Smith chart (sometimes also called Smith diagram, Mizuhashi chart (水橋チャート), Mizuhashi–Smith chart (水橋スミスチャート), [1] [2] [3] Volpert–Smith chart (Диаграмма Вольперта—Смита) [4] [5] or Mizuhashi–Volpert–Smith chart), is a graphical calculator or nomogram designed for electrical and electronics engineers specializing in radio ...

  6. False discovery rate - Wikipedia

    en.wikipedia.org/wiki/False_discovery_rate

    Using MFDR and formulas above, an adjusted MFDR (or AFDR) is the minimum of the mean for m dependent tests, i.e., () = (+) [⁡ +] +. Another way to address dependence is by bootstrapping and rerandomization.

  7. Šidák correction for t-test - Wikipedia

    en.wikipedia.org/wiki/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.If we want to test the locations of multiple sequences of such variables, Šidák correction should be applied in order to calibrate the level of the Student's t-test.

  8. Refractive index - Wikipedia

    en.wikipedia.org/wiki/Refractive_index

    The gem is placed on a high refractive index prism and illuminated from below. A high refractive index contact liquid is used to achieve optical contact between the gem and the prism. At small incidence angles most of the light will be transmitted into the gem, but at high angles total internal reflection will occur in the prism.

  9. Vertex distance - Wikipedia

    en.wikipedia.org/wiki/Vertex_distance

    Since most refractions (the measurement that determines the power of a corrective lens) are performed at a vertex distance of 12–14 mm, the power of the correction may need to be modified from the initial prescription so that light reaches the patient's eye with the same effective power that it did through the phoropter or trial frame.
