The first two population distribution parameters and are usually characterized as location and scale parameters, while the remaining parameter(s), if any, are characterized as shape parameters, e.g. skewness and kurtosis parameters, although the model may be applied more generally to the parameters of any population distribution with up to four ...
NMRA standard S-1.2 covers the popular model railway scales and S-1.3 defines scales with deep flanges for model railways with very sharp curves or other garden railway specific design features. In certain NMRA scales an alternative designation is sometimes used corresponding the length of one prototype foot in scale either in millimetres or in ...
This scale is today the most popular modelling scale in the UK, although it once had some following in the US (on 19 mm / 0.748 in gauge track) before World War II. 00 or "Double-Oh", together with EM gauge and P4 standards are all to 4 mm scale as the scale is the same, but the track standards are incompatible. 00 uses the same track as HO (16 ...
2.059 mm: Model railways (British N) British N model railroad scale. 1:144: 1 ⁄ 12 in: 2.117 mm HOO scale - Popular for ships, aircraft, rockets, spacecraft. Occasionally used with NASCAR cars. Also some Japanese N scale trains, as well as Japanese giant robot models (such as Gunpla) and toys. Dollhouse for a dollhouse scale for 1:12 dollhouses.
OO gauge or OO scale (also, 00 gauge and 00 scale) is the most popular standard gauge model railway standard in the United Kingdom, [1] outside of which it is virtually unknown. OO gauge is one of several 4 mm-scale standards (4 mm to 1 ft (304.8 mm), or 1:76.2), and the only one to be marketed by major manufacturers.
The result of uniform scaling is similar (in the geometric sense) to the original. A scale factor of 1 is normally allowed, so that congruent shapes are also classed as similar. Uniform scaling happens, for example, when enlarging or reducing a photograph, or when creating a scale model of a building, car, airplane, etc. More general is scaling ...
Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building. [1] In such cases the scale is dimensionless and exact throughout the model or drawing. The scale can be expressed in four ways: in words (a lexical scale), as a ratio, as a fraction and as a graphical (bar) scale.
