  2. Quadratic equation - Wikipedia

    en.wikipedia.org/wiki/Quadratic_equation

    In mathematics, a quadratic equation (from Latin quadratus 'square') is an equation that can be rearranged in standard form as [1] + + =, where x represents an unknown value, and a, b, and c represent known numbers, where a ≠ 0.

  3. Error correction code - Wikipedia

    en.wikipedia.org/wiki/Error_correction_code

    Low-density parity-check (LDPC) codes are a class of highly efficient linear block codes made from many single parity check (SPC) codes. They can provide performance very close to the channel capacity (the theoretical maximum) using an iterated soft-decision decoding approach, at linear time complexity in terms of their block length.

  4. 2024 FIA Formula 3 Championship - Wikipedia

    Leonardo Fornaroli became the 2024 FIA Formula 3 Champion, and was the first to do so without any race wins. Prema Racing successfully defended their Teams' Championship title. The 2024 FIA Formula 3 Championship was a motor racing championship for Formula 3 cars sanctioned by the Fédération Internationale de l'Automobile (FIA).

  5. Borderline tree - Wikipedia

    en.wikipedia.org/wiki/Borderline_tree

    It happens when a tree cannot be easily determined as in or out when using a prism or angle gauge. Borderline trees occur only when the distance from the sampling point to the center of the tree is equal to the DBH times plot radius factor (PRF). The PRF is determined based on the type of prism or angle gauge being used.

  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. Dove prism - Wikipedia

    en.wikipedia.org/wiki/Dove_prism

    A Dove prism is a type of reflective prism which is used to invert an image. Dove prisms are shaped from a truncated right-angle prism. The Dove prism is named for its inventor, Heinrich Wilhelm Dove. Although the shape of this prism is similar to the shape described by a Dovetail joint, the etymology of the two is unrelated.

  8. API gravity - Wikipedia

    en.wikipedia.org/wiki/API_gravity

    Temperature correction: If the measurement is not performed at the standard temperature, a correction factor is applied to adjust the reading to the equivalent value at 60°F. [ 6 ] The hydrometer method is widely used due to its simplicity and low cost.

  9. Darcy friction factor formulae - Wikipedia

    en.wikipedia.org/wiki/Darcy_friction_factor_formulae

    If more than one formula is applicable in the flow regime under consideration, the choice of formula may be influenced by one or more of the following: Required accuracy; Speed of computation required; Available computational technology: calculator (minimize keystrokes) spreadsheet (single-cell formula) programming/scripting language (subroutine).
