The scale of a map or enlarged or reduced model indicates the ratio between the distances on the map or model and the corresponding distances in reality or the original.
a map of scale 1:50,000 shows a distance of 50,000 cm (=500 m) as 1 cm on a map, and a model on a scale 1:25 of a building with a height of 30 m has a model height of 1.20 m.

 Measurement
Measurement is the assignment of numbers to objects in such a way that physical relationships and operations among the objects correspond to arithmetic relationships and operations among the numbers.
Different levels of measurement are defined by the number and kind of correspondences that hold between the physical relations among objects and the arithmetic relations among the scores.
The different levels of measurement are distinguished by which arithmetic operations on the measured scores have counterparts in physical operations on the objects.

Photogrametry is a method to determine the spatial distribution of microstrains at the sample surface by measurement of changes in the three dimensional plastic displacement field during a deformation experiment [1, 8].
In order to measure the three dimensional surface coordinates digital stereo pair images of the sample were acquired using two high resolution CCD cameras as shown in Fig.
The resulting gray scale pattern on the surface of the specimen was recorded and reference coordinates for the different experimental methods (microtexture, metallography, microstrain determination) were fixed on the sample surface.

As an example, a possible way to measure path capacity is to blast the path with a continuous stream of UDP packets that will gradually eliminate the congestion-responsive TCP traffic from the link, and measure (by consuming) the maximum possible throughput.
Paxson observed that the distribution of bandwidth measurements is multimodal, and he elaborated on the identification and final selection of a capacity estimate from these modes [21].
Better bandwidth measurement algorithms are needed by a large class of network applications, traffic engineers controlling path selection and service class differentiation, and users wanting to verify they are receiving the access bandwidth they expect.

By measuring mRNA turnover rates comprehensively, we identified unexpected relationships between the function of a gene and its mRNA stability.
The adjusted R-squared statistic, which is a measure of correlation between the observed data values and the predicted values from the linear model, shows how well a first-order kinetics model would describe the mRNA degradation rates.
First, the mRNA abundance at X h, as measured by the ratio of the array element (Cy5/Cy3) must have decreased by at least twofold.

The standard unit of linear measurement used by carpenters was the ‘royal cubit’, which was based on the length of a man’s forearm.
Although these measurements were standardised, ‘royal cubit rods’ have been discovered, as one might expect, with an error of up to plus or minus 2 mm in overall length.
The author has found that evidence of measurement can also be seen on other types of furniture where the ‘royal cubit’ or ‘short cubit’ were often used as the initial measure to determine either the length, width or height of a piece of furniture.

The thermal properties include thermal diffusivity, thermal conductivity, emissivity and transmissivity, and they may need to be measured on a small scale, as in the case of semiconductors, or in-situ in situations where sample preparation is impractical.
For example, the validity of a particular radiation-based thermometry measurement on gas turbine blades can be verified by checking the instrument against a LART instrument in a laboratory simulation of the blade environment.

Paired comparisons of a heterogeneous set of ten natural sounds were collected from 60 listeners in order to determine: (1) if the sensation of unpleasantness is judged consistently across a wide range of acoustic stimuli; and (2) which sound features contribute to that sensation.
The judgments conformed with the highly restrictive BTL model [R. Luce, Individual Choice Behavior (Wiley, New York, 1959)], thus justifying ratio-scale representation of perceived unpleasantness.
The resulting scale values varied by a factor of 100 (diesel engine versus jackhammer).

ABSTRACT: The extent to which there are aggregate returns to scale at the level of aggregate production has important implications both for the types of shocks generating business cycles and for optimal policy.
However, prior attempts to measure the extent of these returns using instrumental variable techniques have yielded quite imprecise estimates.
In this article, we show that the production shocks implied by a range of returns to scale that encompasses both large increasing returns and large decreasing returns are almost identical.
