  2. Scaling (geometry) - Wikipedia

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

    Such a scaling changes the diameter of an object by a factor between the scale factors, the area by a factor between the smallest and the largest product of two scale factors, and the volume by the product of all three. The scaling is uniform if and only if the scaling factors are equal (v x = v y = v z). If all except one of the scale factors ...

  3. Fractal - Wikipedia

    en.wikipedia.org/wiki/Fractal

    We see that for ordinary self-similar objects, being n-dimensional means that when it is rep-tiled into pieces each scaled down by a scale-factor of 1/r, there are a total of r n pieces. Now, consider the Koch curve. It can be rep-tiled into four sub-copies, each scaled down by a scale-factor of 1/3.

  4. Aerial photographic and satellite image interpretation

    en.wikipedia.org/wiki/Aerial_photographic_and...

    Reaching the requirements of the two chosen, overlapping images is simple. The principal points (central point of the image in geometry) of the two photos must be in different locations on the terrain. [2] Another restriction is that the scale of the images must be the same. [2] The flying routes of the planes and the time of day are not ...

  5. Similarity (geometry) - Wikipedia

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

    If two angles of a triangle have measures equal to the measures of two angles of another triangle, then the triangles are similar. Corresponding sides of similar polygons are in proportion, and corresponding angles of similar polygons have the same measure. Two congruent shapes are similar, with a scale factor of 1. However, some school ...

    Such a scaling changes the diameter of an object by a factor between the scale factors, the area by a factor between the smallest and the largest product of two scale factors, and the volume by the product of all three. The scaling is uniform if and only if the scaling factors are equal (v x = v y = v z). If all except one of the scale factors ...

  7. Fractal dimension - Wikipedia

    en.wikipedia.org/wiki/Fractal_dimension

    The theoretical fractal dimension for this fractal is 5/3 ≈ 1.67; its empirical fractal dimension from box counting analysis is ±1% [8] using fractal analysis software. A fractal dimension is an index for characterizing fractal patterns or sets by quantifying their complexity as a ratio of the change in detail to the change in scale.

  8. Spacetime - Wikipedia

    en.wikipedia.org/wiki/Spacetime

    A scale factor, (conventionally called the speed-of-light) relates distances measured in space to distances measured in time. The magnitude of this scale factor (nearly 300,000 kilometres or 190,000 miles in space being equivalent to one second in time), along with the fact that spacetime is a manifold, implies that at ordinary, non ...

  9. Elliptic coordinate system - Wikipedia

    en.wikipedia.org/wiki/Elliptic_coordinate_system

    The scale factors for the elliptic coordinates (,) are equal to = = ⁡ + ⁡ = ⁡ ⁡. Using the double argument identities for hyperbolic functions and trigonometric functions, the scale factors can be equivalently expressed as
