  2. Girard form class - Wikipedia

    en.wikipedia.org/wiki/Girard_form_class

    Girard form class is a form quotient calculated as the ratio of diameter inside bark at the top of the first 16 foot log to the diameter outside bark at breast height ().Its purpose is to estimate board-foot volume of whole trees from measurement of DBH, estimation of the number of logs, and estimation of the taper of the first log, based on the general relationships identified between the ...

  3. Tree measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_measurement

    To calculate trunk volume, the tree is subdivided into a series of segments with the successive diameters being the bottom and top of each segment and its length equal to the difference in height between the lower and upper diameter. Cumulative trunk volume is calculated by adding the volume of the measured segments of the tree together.

  4. Tree volume measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_volume_measurement

    To calculate trunk volume, the tree is subdivided into a series of segments with the successive diameters being the bottom and top of each segment and segment length being equal to the difference in height between the lower and upper diameters, or if the trunk is not vertical, the segment length can be calculated using the limb length formula ...

  6. Floor area ratio - Wikipedia

    en.wikipedia.org/wiki/Floor_area_ratio

    Floor Area ratio is sometimes called floor space ratio (FSR), floor space index (FSI), site ratio or plot ratio. The difference between FAR and FSI is that the first is a ratio, while the latter is an index. Index numbers are values expressed as a percentage of a single base figure. Thus an FAR of 1.5 is translated as an FSI of 150%.

    For example, the perihelion precession of Mercury could only be explained after the emergence of Einstein's general relativity, which replaced Newton's law of gravitation as a better mathematical model. [104] There is still a philosophical debate whether mathematics is a science. However, in practice, mathematicians are typically grouped with ...

  8. Coverage probability - Wikipedia

    en.wikipedia.org/wiki/Coverage_probability

    By contrast, the (true) coverage probability is the actual probability that the interval contains the parameter. If all assumptions used in deriving a confidence interval are met, the nominal coverage probability will equal the coverage probability (termed "true" or "actual" coverage probability for emphasis).

  9. Debt service coverage ratio - Wikipedia

    en.wikipedia.org/wiki/Debt_service_coverage_ratio

    The debt service coverage ratio (DSCR), also known as "debt coverage ratio" (DCR), is a financial metric used to assess an entity's ability to generate enough cash to cover its debt service obligations, such as interest, principal, and lease payments. The DSCR is calculated by dividing the operating income by the total amount of debt service due.
