  2. MUSCL scheme - Wikipedia

    en.wikipedia.org/wiki/MUSCL_scheme

    This illustrates clearly demonstrates the effectiveness of the MUSCL approach to solving the Euler equations. The simulation was carried out on a mesh of 200 cells using Matlab code (Wesseling, 2001), adapted to use the KT algorithm and Ospre limiter. Time integration was performed by a 4th order SHK (equivalent performance to RK-4) integrator.

  3. Model order reduction - Wikipedia

    en.wikipedia.org/wiki/Model_order_reduction

    MORLAB: Model Order Reduction Laboratory. This toolbox is a collection of MATLAB/OCTAVE routines for model order reduction of linear dynamical systems based on the solution of matrix equations. The implementation is based on spectral projection methods, e.g., methods based on the matrix sign function and the matrix disk function.

  4. Color moments - Wikipedia

    en.wikipedia.org/wiki/Color_moments

    Computing the features - Use the color moments formulae in order to compute the first three moments for each of the color channels in the image. For example, if the HSV color space is used, this means that for each of the images, 9 features in total will be computed (the first three order moments for the Hue, Saturation, and Value channels).

  5. HSL and HSV - Wikipedia

    en.wikipedia.org/wiki/HSL_and_HSV

    Fig. 1. HSL (a–d) and HSV (e–h). Above (a, e): cut-away 3D models of each. Below: two-dimensional plots showing two of a model's three parameters at once, holding the other constant: cylindrical shells (b, f) of constant saturation, in this case the outside surface of each cylinder; horizontal cross-sections (c, g) of constant HSL lightness or HSV value, in this case the slices halfway ...

  6. Sliding mode control - Wikipedia

    en.wikipedia.org/wiki/Sliding_mode_control

    which is a reduced-order system (i.e., the new system is of order because the system is constrained to this ()-dimensional sliding mode simplex). This surface may have favorable properties (e.g., when the plant dynamics are forced to slide along this surface, they move toward the origin x = 0 {\displaystyle \mathbf {x} =\mathbf {0} } ).

  7. State-space representation - Wikipedia

    en.wikipedia.org/wiki/State-space_representation

    The internal state variables are the smallest possible subset of system variables that can represent the entire state of the system at any given time. [13] The minimum number of state variables required to represent a given system, , is usually equal to the order of the system's defining differential equation, but not necessarily.

  8. LMS color space - Wikipedia

    en.wikipedia.org/wiki/LMS_color_space

    The LMS color space can be used to emulate the way color-blind people see color. An early emulation of dichromats were produced by Brettel et al. 1997 and was rated favorably by actual patients. An early emulation of dichromats were produced by Brettel et al. 1997 and was rated favorably by actual patients.

  9. Verlet integration - Wikipedia

    en.wikipedia.org/wiki/Verlet_integration

    The matrix code can be reused: The dependency of the forces on the positions can be approximated locally to first order, and the Verlet integration can be made more implicit. Sophisticated software, such as SuperLU [7] exists to solve complex problems using sparse matrices.
