    en.wikipedia.org/wiki/0,10_Exhibition

    The Last Futurist Exhibition of Paintings 0,10 (pronounced "zero-ten") [2] was an exhibition presented by the Dobychina Art Bureau at Marsovo Pole, Petrograd, from 19 December 1915 to 17 January 1916.

  3. Arithmetic coding - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_coding

    The above explanations of arithmetic coding contain some simplification. In particular, they are written as if the encoder first calculated the fractions representing the endpoints of the interval in full, using infinite precision, and only converted the fraction to its final form at the end of encoding. Rather than try to simulate infinite ...

  4. Amdahl's law - Wikipedia

    en.wikipedia.org/wiki/Amdahl's_law

    "the overall performance improvement gained by optimizing a single part of a system is limited by the fraction of time that the improved part is actually used". [ 2 ] It is named after computer scientist Gene Amdahl , and was presented at the American Federation of Information Processing Societies (AFIPS) Spring Joint Computer Conference in 1967.

  5. NACA airfoil - Wikipedia

    "a=" followed by a decimal number describing the fraction of chord over which laminar flow is maintained. a=1 is the default if no value is given. For example, the NACA 65 4 -415, has the minimum pressure placed at 50% of the chord, has a maximum thickness of 15% of the chord, design lift coefficient of 0.4 and maintains laminar flow for lift ...

  6. Abundance of the chemical elements - Wikipedia

    en.wikipedia.org/wiki/Abundance_of_the_chemical...

    The abundance of the chemical elements is a measure of the occurrences of the chemical elements relative to all other elements in a given environment. Abundance is measured in one of three ways: by mass fraction (in commercial contexts often called weight fraction), by mole fraction (fraction of atoms by numerical count, or sometimes fraction of molecules in gases), or by volume fraction.

  7. Overpotential - Wikipedia

    en.wikipedia.org/wiki/Overpotential

    Voltage efficiency describes the fraction of energy lost through overpotential. For an electrolytic cell this is the ratio of a cell's thermodynamic potential divided by the cell's experimental potential converted to a percentile.

  8. Chi-squared distribution - Wikipedia

    en.wikipedia.org/wiki/Chi-squared_distribution

    The generalized chi-squared distribution is obtained from the quadratic form z'Az where z is a zero-mean Gaussian vector having an arbitrary covariance matrix, and A is an arbitrary matrix. Gamma, exponential, and related distributions

  9. Distillation - Wikipedia

    en.wikipedia.org/wiki/Distillation

    Continuous distillation produces a minimum of two output fractions, including at least one volatile distillate fraction, which has boiled and been separately captured as a vapor and then condensed to a liquid. There is always a bottoms (or residue) fraction, which is the least volatile residue that has not been separately captured as a ...
