  2. Scaling (geometry) - Wikipedia

    en.wikipedia.org/wiki/Scaling_(geometry)

    In uniform scaling with a non-zero scale factor, all non-zero vectors retain their direction (as seen from the origin), or all have the direction reversed, depending on the sign of the scaling factor. In non-uniform scaling only the vectors that belong to an eigenspace will retain their direction. A vector that is the sum of two or more non ...

  3. Invariant (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Invariant_(mathematics)

    The three angle measures of a triangle are also invariant under rigid motions, but do not form a complete set as incongruent triangles can share the same angle measures. However, if one allows scaling in addition to rigid motions, then the AAA similarity criterion shows that this is a complete set of invariants.

  4. Procrustes transformation - Wikipedia

    en.wikipedia.org/wiki/Procrustes_transformation

    A Procrustes transformation is a geometric transformation that involves only translation, rotation, uniform scaling, or a combination of these transformations.Hence, it may change the size, position, and orientation of a geometric object, but not its shape.

  5. Procrustes analysis - Wikipedia

    en.wikipedia.org/wiki/Procrustes_analysis

    Likewise, the scale component can be removed by scaling the object so that the root mean square distance (RMSD) from the points to the translated origin is 1. This RMSD is a statistical measure of the object's scale or size: = (¯) + (¯) +

  6. Scale (ratio) - Wikipedia

    en.wikipedia.org/wiki/Scale_(ratio)

    Graphical scale bar in combination with a scale expressed as a ratio and a conversion help. The scale ratio of a model represents the proportional ratio of a linear dimension of the model to the same feature of the original. Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building ...

  7. Multiprocessor system architecture - Wikipedia

    en.wikipedia.org/wiki/Multiprocessor_system...

    The main characteristic of a cc-NUMA system is having shared global memory that is distributed to each node, although the effective "access" a processor has to the memory of a remote component subsystem, or "node", is slower compared to local memory access, which is why the memory access is "non-uniform".

  8. Image scaling - Wikipedia

    en.wikipedia.org/wiki/Image_scaling

    Image scaling can be interpreted as a form of image resampling or image reconstruction from the view of the Nyquist sampling theorem.According to the theorem, downsampling to a smaller image from a higher-resolution original can only be carried out after applying a suitable 2D anti-aliasing filter to prevent aliasing artifacts.

  9. Non-dimensionalization and scaling of the Navier–Stokes ...

    en.wikipedia.org/wiki/Non-dimensionalization_and...

    Scaling of Navier–Stokes equation refers to the process of selecting the proper spatial scales – for a certain type of flow – to be used in the non-dimensionalization of the equation. Since the resulting equations need to be dimensionless, a suitable combination of parameters and constants of the equations and flow (domain ...
