  2. Oil and gas reserves and resource quantification - Wikipedia

    en.wikipedia.org/wiki/Oil_and_gas_reserves_and...

    Reserves and resource reporting. An oil or gas resource refers to known (discovered fields) or potential accumulations of oil and/or gas (i.e undiscovered prospects and leads) in the subsurface of the Earth's crust. All reserve and resource estimates involve uncertainty in volume estimates (expressed below as Low, Mid or High uncertainty), as ...

  3. Weibull distribution - Wikipedia

    en.wikipedia.org/wiki/Weibull_distribution

    In probability theory and statistics, the Weibull distribution / ˈwaɪbʊl / is a continuous probability distribution. It models a broad range of random variables, largely in the nature of a time to failure or time between events. Examples are maximum one-day rainfalls and the time a user spends on a web page.

  4. Percentile - Wikipedia

    en.wikipedia.org/wiki/Percentile

    Percentile. Statistic which divides a data set into 100 parts and analyzes it as a percentage. In statistics, a k-th percentile, also known as percentile score or centile, is a score below which a given percentage k of scores in its frequency distribution falls (" exclusive " definition) or a score at or below which a given percentage falls ...

  5. Uncertainty quantification - Wikipedia

    en.wikipedia.org/wiki/Uncertainty_quantification

    Uncertainty quantification. Uncertainty quantification (UQ) is the science of quantitative characterization and estimation of uncertainties in both computational and real world applications. It tries to determine how likely certain outcomes are if some aspects of the system are not exactly known. An example would be to predict the acceleration ...

  7. FN P90 - Wikipedia

    en.wikipedia.org/wiki/FN_P90

    The P90 LV (Laser Visible) and P90 IR (InfraRed) models, both of which were introduced in late 1995, have an integrated laser sight manufactured by Laserex Technologies in Australia. [36] The P90 LV model projects an 8 mW visible laser intended to be used as a low-light shooting aid or for dissuasive effect, while the P90 IR model projects a 4. ...

  8. Pulse pressure - Wikipedia

    en.wikipedia.org/wiki/Pulse_pressure

    Pulse pressure is the difference between systolic and diastolic blood pressure. [1] It is measured in millimeters of mercury (mmHg). It represents the force that the heart generates each time it contracts. Healthy pulse pressure is around 40 mmHg. [1][2] A pulse pressure that is consistently 60 mmHg or greater is likely to be associated with ...

  9. Statistical dispersion - Wikipedia

    en.wikipedia.org/wiki/Statistical_dispersion

    In statistics, dispersion (also called variability, scatter, or spread) is the extent to which a distribution is stretched or squeezed. [1] Common examples of measures of statistical dispersion are the variance, standard deviation, and interquartile range. For instance, when the variance of data in a set is large, the data is widely scattered ...
