  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%.

  7. Girdling - Wikipedia

    en.wikipedia.org/wiki/Girdling

    A farmer would place a girdle (bark removal) at base of a large branch or at the trunk. Thus, all sugars manufactured by the leaves have no sinks but the fruit, which grows to above the normal size. For grapes girdling or cincturing is used to make the grapes large and sweeter on the grape canopy and are sold as girdled grapes.

  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. Spark spread - Wikipedia

    en.wikipedia.org/wiki/Spark_spread

    The terms dark spread, quark spread and bark spread [1] [2] refer to the similarly defined differences ("spreads") between cash streams for coal-fired power plants, nuclear power plants and bio-mass power plants, respectively.
