  2. Cooling load temperature difference calculation method

    en.wikipedia.org/wiki/Cooling_load_temperature...

    The first of the cooling load factors used in this method is the CLTD, or the Cooling Load Temperature Difference. This factor is used to represent the temperature difference between indoor and outdoor air with the inclusion of the heating effects of solar radiation. [1] [5] The second factor is the CLF, or the cooling load factor.

  4. Challenge-Handshake Authentication Protocol - Wikipedia

    en.wikipedia.org/wiki/Challenge-Handshake...

    In computing, the Challenge-Handshake Authentication Protocol (CHAP) is an authentication protocol originally used by Point-to-Point Protocol (PPP) to validate users. CHAP is also carried in other authentication protocols such as RADIUS and Diameter. Almost all network operating systems support PPP with CHAP, as do most network access servers.

  5. Trapeze (spreadsheet program) - Wikipedia

    en.wikipedia.org/wiki/Trapeze_(spreadsheet_program)

    It introduced the concept of using named ranges for most operations instead of cell addresses, allowing formulas to be freed of the location of the data on the page. This, in turn, made updating the sheets by moving data around a safe operation, whereas in contemporary programs like Microsoft Excel and Lotus 1-2-3 this often led to broken ...

  6. Friedman test - Wikipedia

    en.wikipedia.org/wiki/Friedman_test

    Not all statistical packages support post-hoc analysis for Friedman's test, but user-contributed code exists that provides these facilities (for example in SPSS, [10] and in R. [11]). The R package titled PMCMRplus contains numerous non-parametric methods for post-hoc analysis after Friedman, [ 12 ] including support for the Nemenyi test .

  7. Finite difference method - Wikipedia

    en.wikipedia.org/wiki/Finite_difference_method

    For example, consider the ordinary differential equation ′ = + The Euler method for solving this equation uses the finite difference quotient (+) ′ to approximate the differential equation by first substituting it for u'(x) then applying a little algebra (multiplying both sides by h, and then adding u(x) to both sides) to get (+) + (() +).

  8. Compact finite difference - Wikipedia

    en.wikipedia.org/wiki/Compact_finite_difference

    The classical Pade scheme for the first derivative at a cell with index (′) reads; ′ + ′ + + ′ = +. Where is the spacing between points with index , & +.The equation yields a fourth-order accurate solution for ′ when supplemented with suitable boundary conditions (typically periodic).

  9. Stencil (numerical analysis) - Wikipedia

    en.wikipedia.org/wiki/Stencil_(numerical_analysis)

    The finite difference coefficients for a given stencil are fixed by the choice of node points. The coefficients may be calculated by taking the derivative of the Lagrange polynomial interpolating between the node points, [3] by computing the Taylor expansion around each node point and solving a linear system, [4] or by enforcing that the stencil is exact for monomials up to the degree of the ...
