  2. Vertical integration - Wikipedia

    en.wikipedia.org/wiki/Vertical_integration

    Vertical integration is the degree to which a firm owns its upstream suppliers and its downstream buyers. The differences depend on where the firm is placed in the order of the supply chain. There are three varieties of vertical integration: backward (upstream) vertical integration, forward (downstream) vertical integration, and balanced (both ...

  3. Horizontal integration - Wikipedia

    en.wikipedia.org/wiki/Horizontal_integration

    Marketing. Horizontal integration is the process of a company increasing production of goods or services at the same level of the value chain, in the same industry. A company may do this via internal expansion or through mergers and acquisitions. [ 1][ 2][ 3] The process can lead to monopoly if a company captures the vast majority of the market ...

  4. Fubini's theorem - Wikipedia

    en.wikipedia.org/wiki/Fubini's_theorem

    One generally also assumes that the measures on and are complete, otherwise the two partial integrals along vertical or horizontal lines may be well-defined but not measurable. For example, if f {\displaystyle f} is the characteristic function of a product of a measurable set and a non-measurable set contained in a measure 0 set then its single ...

  5. Integration by parts - Wikipedia

    en.wikipedia.org/wiki/Integration_by_parts

    Integration by parts is a heuristic rather than a purely mechanical process for solving integrals; given a single function to integrate, the typical strategy is to carefully separate this single function into a product of two functions u(x)v(x) such that the residual integral from the integration by parts formula is easier to evaluate than the ...

  6. Lebesgue integral - Wikipedia

    en.wikipedia.org/wiki/Lebesgue_integral

    e. In mathematics, the integral of a non-negative function of a single variable can be regarded, in the simplest case, as the area between the graph of that function and the X axis. The Lebesgue integral, named after French mathematician Henri Lebesgue, is one way to make this concept rigorous and to extend it to more general functions.

    List of Jim Crow law examples by state. A Black American drinks from a segregated water cooler in 1939 at a streetcar terminal in Oklahoma City. This is a list of examples of Jim Crow laws, which were state, territorial, and local laws in the United States enacted between 1877 and 1965. Jim Crow laws existed throughout the United States and ...

  8. Horizontal integration facility - Wikipedia

    en.wikipedia.org/wiki/Horizontal_Integration...

    Construction was completed in June 2000. Its floors are said to be the most level in the United States, varying less than 0.38 in (9.6 mm) across each bay. The first and second stages of the rocket, along with any boosters that are being used for that flight, are integrated in the HIF, and then the stack is moved to the pad and raised to vertical.

  9. Geodetic datum - Wikipedia

    en.wikipedia.org/wiki/Geodetic_datum

    A vertical datum is a reference surface for vertical positions, such as the elevations of Earth features including terrain, bathymetry, water level, and human-made structures. An approximate definition of sea level is the datum WGS 84 , an ellipsoid , whereas a more accurate definition is Earth Gravitational Model 2008 (EGM2008), using at least ...
