  2. Thermodynamic databases for pure substances - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_databases...

    Thermodynamic data is usually presented as a table or chart of function values for one mole of a substance (or in the case of the steam tables, one kg). A thermodynamic datafile is a set of equation parameters from which the numerical data values can be calculated. Tables and datafiles are usually presented at a standard pressure of 1 bar or 1 ...

  3. Enthalpy–entropy chart - Wikipedia

    en.wikipedia.org/wiki/Enthalpy–entropy_chart

    The Mollier enthalpy–entropy diagram for water and steam. The "dryness fraction", x , gives the fraction by mass of gaseous water in the wet region, the remainder being droplets of liquid. An enthalpy–entropy chart , also known as the H – S chart or Mollier diagram , plots the total heat against entropy, [ 1 ] describing the enthalpy of a ...

    Joseph Henry Keenan (August 24, 1900 – July 17, 1977) was an American thermodynamicist and mechanical engineer noted for his work in the calculation of steam tables, research in jet-rocket propulsion, and his work in furthering the development in the understanding of the laws of thermodynamics in the mid 20th century.

  6. Bicubic interpolation - Wikipedia

    en.wikipedia.org/wiki/Bicubic_interpolation

    In mathematics, bicubic interpolation is an extension of cubic spline interpolation (a method of applying cubic interpolation to a data set) for interpolating data points on a two-dimensional regular grid.

  7. Difference engine - Wikipedia

    en.wikipedia.org/wiki/Difference_engine

    The London Science Museum's difference engine, the first one actually built from Babbage's design. The design has the same precision on all columns, but in calculating polynomials, the precision on the higher-order columns could be lower.

  9. Lanczos resampling - Wikipedia

    en.wikipedia.org/wiki/Lanczos_resampling

    Lanczos windows for a = 1, 2, 3. Lanczos kernels for the cases a = 1, 2, and 3, with their frequency spectra. A sinc filter would have a cutoff at frequency 0.5. The effect of each input sample on the interpolated values is defined by the filter's reconstruction kernel L(x), called the Lanczos kernel.
