  2. MacCormack method - Wikipedia

    en.wikipedia.org/wiki/MacCormack_method

    The application of MacCormack method to the above equation proceeds in two steps; a predictor step which is followed by a corrector step. Predictor step: In the predictor step, a "provisional" value of u {\displaystyle u} at time level n + 1 {\displaystyle n+1} (denoted by u i p {\displaystyle u_{i}^{p}} ) is estimated as follows

  3. CHAPS detergent - Wikipedia

    en.wikipedia.org/wiki/CHAPS_detergent

    CHAPS is a zwitterionic surfactant used in the laboratory to solubilize biological macromolecules such as proteins.It may be synthesized from cholic acid [1] and is zwitterionic due to its quaternary ammonium and sulfonate groups; it is structurally similar to certain bile acids, such as taurodeoxycholic acid and taurochenodeoxycholic acid.

  4. Chapman–Kolmogorov equation - Wikipedia

    en.wikipedia.org/wiki/Chapman–Kolmogorov_equation

    As a corollary, it follows that to calculate the transition matrix of jump t, it is sufficient to raise the transition matrix of jump one to the power of t, that is =. The differential form of the Chapman–Kolmogorov equation is known as a master equation.

  5. MUSCL scheme - Wikipedia

    en.wikipedia.org/wiki/MUSCL_scheme

    In the study of partial differential equations, the MUSCL scheme is a finite volume method that can provide highly accurate numerical solutions for a given system, even in cases where the solutions exhibit shocks, discontinuities, or large gradients.

  6. Difference engine - Wikipedia

    en.wikipedia.org/wiki/Difference_engine

    A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions. It was designed in the 1820s, and was created by Charles Babbage . The name difference engine is derived from the method of finite differences , a way to interpolate or tabulate functions by using a small set of polynomial co-efficients.

  7. 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 ...

  8. Meshfree methods - Wikipedia

    en.wikipedia.org/wiki/Meshfree_methods

    Then we can use these definitions of (,) and its spatial derivatives to write the equation being simulated as an ordinary differential equation, and simulate the equation with one of many numerical methods. In physical terms, this means calculating the forces between the particles, then integrating these forces over time to determine their motion.

  9. Chapman–Enskog theory - Wikipedia

    en.wikipedia.org/wiki/Chapman–Enskog_theory

    The difference in this equation from classical Chapman–Enskog theory lies in the streaming operator , within which the velocity distribution of the two particles are evaluated at different points in space, separated by , where is the unit vector along the line connecting the two particles centre of mass.
