  2. Error analysis for the Global Positioning System - Wikipedia

    en.wikipedia.org/wiki/Error_analysis_for_the...

    Some military and expensive survey-grade civilian receivers calculate atmospheric dispersion from the different delays in the L1 and L2 frequencies, and apply a more precise correction. This can be done in civilian receivers without decrypting the P(Y) signal carried on L2, by tracking the carrier wave instead of the modulated code.

    1. How about an illustration of the difference that prismatic lenses make in a user's view over that of regular lenses? 2. How about an illustration to visually explain what it meant by the "prism dioptres" section? 3. Can prismatic lenses be included with bifocals, progressive lenses, polarizing, tinting, Crizol lenses, etc? 4.

  4. Characteristic length - Wikipedia

    en.wikipedia.org/wiki/Characteristic_length

    In physics, a characteristic length is an important dimension that defines the scale of a physical system. Often, such a length is used as an input to a formula in order to predict some characteristics of the system, and it is usually required by the construction of a dimensionless quantity, in the general framework of dimensional analysis and in particular applications such as fluid mechanics.

  5. Frustum - Wikipedia

    en.wikipedia.org/wiki/Frustum

    Square frustum A regular octahedron can be augmented on 3 faces to create a triangular frustum. A frustum's axis is that of the original cone or pyramid. A frustum is circular if it has circular bases; it is right if the axis is perpendicular to both bases, and oblique otherwise.

  6. 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]

  7. Welch's t-test - Wikipedia

    en.wikipedia.org/wiki/Welch's_t-test

    It is named for its creator, Bernard Lewis Welch, and is an adaptation of Student's t-test, [1] and is more reliable when the two samples have unequal variances and possibly unequal sample sizes. [ 2 ] [ 3 ] These tests are often referred to as "unpaired" or "independent samples" t -tests, as they are typically applied when the statistical ...

  8. Tukey's range test - Wikipedia

    en.wikipedia.org/wiki/Tukey's_range_test

    Tukey's range test, also known as Tukey's test, Tukey method, Tukey's honest significance test, or Tukey's HSD (honestly significant difference) test, [1] is a single-step multiple comparison procedure and statistical test.

  9. History of Formula One - Wikipedia

    en.wikipedia.org/wiki/History_of_Formula_One

    This new "International Formula" was initially known variously as Formula A, Formula I, or Formula 1 with the corresponding "Voiturette" formula being titled Formula B, Formula II, or Formula 2. [2] When the 500cc formula was internationally recognised as Formula 3 in 1950 it was never titled as "Formula C" so the three International Formulae ...
