  • 121Scale invariance — In physics and mathematics, scale invariance is a feature of objects or laws that do not change if length scales (or energy scales) are multiplied by a common factor. The technical term for this transformation is a dilatation (also known as… …

  • 124Power law — A power law is any polynomial relationship that exhibits the property of scale invariance. The most common power laws relate two variables and have the form:f(x) = ax^k! +o(x^k),where a and k are constants, and o(x^k) is of x. Here, k is… …

  • 128Scale factor (computer science) — A scale factor is used in computer science when a real world set of numbers needs to be represented on a different scale in order to fit a specific number format. For instance, a 16 bit unsigned integer ( uint16 ) can only hold a value as large… …
