  • 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.
  • Confidence interval
    In statistics, a confidence interval (CI) is a type of interval estimate of a population parameter.
  • Observational error
    Observational error (or measurement error) is the difference between a measured value of quantity and its true value.
  • Distance
    Distance is a numerical description of how far apart objects are.
  • 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.
  • 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.
  • 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.
  • 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.
  • Uncertainty
    Uncertainty is a situation which involves imperfect and/or unknown information.
  • 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.
  • Scale (map)
    The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground.
  • 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.
  • System of measurement
    A system of measurement is a collection of units of measurement and rules relating them to each other.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • Flow measurement
    Flow measurement is the quantification of bulk fluid movement.
  • 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.
  • 3D data acquisition and object reconstruction
    3D data acquisition and reconstruction is the generation of three-dimensional or spatiotemporal models from sensor data.
  • 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".
  • Measurement uncertainty
    In metrology, measurement uncertainty is a non-negative parameter characterizing the dispersion of the values attributed to a measured quantity.
  • Current sensing techniques
    Current sensing is a vital task in electrical sector, where the current information is required for monitoring and control purposes.
  • Weights and Measures Acts (UK)
    Weights and measures acts are acts of the British Parliament determining the regulation of weights and measures.
  • Rate (mathematics)
    In mathematics, a rate is the ratio between two related quantities.
  • 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.
  • Studentized residual
    In statistics, a studentized residual is the quotient resulting from the division of a residual by an estimate of its standard deviation.
