Flatland: A Romance of Many Dimensions is a satirical novella by the English schoolmaster Edwin Abbott Abbott, first published in 1884 by Seeley & Co.
Standard conditions for temperature and pressure
Standard conditions for temperature and pressure are standard sets of conditions for experimental measurements to be established to allow comparisons to be made between different sets of data.
Measurement
Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events.
Nondestructive testing
Nondestructive testing or Non-destructive testing (NDT) is a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage.
Uncertainty
Uncertainty is a situation which involves imperfect and/or unknown information.
High availability
High availability is a characteristic of a system, which aims to ensure an agreed level of operational performance, usually uptime, for a higher than normal period.
Vernier scale
A vernier scale is a device that lets the user measure more precisely than could be done unaided when reading a uniformly divided straight or circular measurement scale.
Confidence interval
In statistics, a confidence interval (CI) is a type of interval estimate of a population parameter.
Scale (map)
The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground.
Observational error
Observational error (or measurement error) is the difference between a measured value of quantity and its true value.
Colorimetry
Colorimetry (American English) or Colourimetry (British English; see spelling differences) is "the science and technology used to quantify and describe physically the human color perception.
System of measurement
A system of measurement is a collection of units of measurement and rules relating them to each other.
Calibration
Calibration in measurement technology and metrology is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy.
Flow measurement
Flow measurement is the quantification of bulk fluid movement.
Distance
Distance is a numerical description of how far apart objects are.
Weights and Measures Acts (UK)
Weights and measures acts are acts of the British Parliament determining the regulation of weights and measures.
Cross section (physics)
The cross section is an effective area that quantifies the intrinsic likelihood of a scattering event when an incident beam strikes a target object, made of discrete particles.
3D data acquisition and object reconstruction
3D data acquisition and reconstruction is the generation of three-dimensional or spatiotemporal models from sensor data.
Physical constant
A physical constant, sometimes fundamental physical constant, is a physical quantity that is generally believed to be both universal in nature and having constant value in time.
Current sensing techniques
Current sensing is a vital task in electrical sector, where the current information is required for monitoring and control purposes.
Rate (mathematics)
In mathematics, a rate is the ratio between two related quantities.
Measurement uncertainty
In metrology, measurement uncertainty is a non-negative parameter characterizing the dispersion of the values attributed to a measured quantity.
Reproducibility
Reproducibility is the ability of an entire experiment or study to be duplicated, either by the same researcher or by someone else working independently.
Errors and residuals
In statistics and optimization, errors and residuals are two closely related and easily confused measures of the deviation of an observed value of an element of a statistical sample from its "theoretical value".
UXR
The User Experience Rating (UXR) is a metric that correlates IT end-user experience with application wait times.
Level of measurement
Level of measurement or scale of measure is a classification that describes the nature of information within the numbers assigned to variables.
Pulse-per-second signal
A pulse per second (PPS or 1PPS) is an electrical signal that has a width of less than one second and a sharply rising or abruptly falling edge that accurately repeats once per second.
Concrete number
A concrete number is a number associated with the things being counted, in contrast to an abstract number which is a number as a single entity.
Signal-to-noise ratio
Signal-to-noise ratio (abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise.

Studentized residual
In statistics, a studentized residual is the quotient resulting from the division of a residual by an estimate of its standard deviation.
