  2. Tree crown measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_crown_measurement

    All four circumscribe the crown area's drip-line with a polygon and divide the polygon into a series of adjacent triangles, measure the area of each triangle and sum them. One option, the Polygonal Method, measures each side of a triangle to compute its area. The second and third methods uses azimuths and one distance to the trunk calculate the ...

  3. Nuclear drip line - Wikipedia

    en.wikipedia.org/wiki/Nuclear_drip_line

    Up to germanium, the location of the drip line for many elements with an even number of protons is known, but none past that point are listed in the evaluated nuclear data. There are a few exceptional cases where, due to nuclear pairing, there are some particle-bound species outside the drip line, such as 8 B and 178 Au.

    en.wikipedia.org/wiki/Drip_line

    Drip line may refer to: Nuclear drip line, the lines beyond which protons or neutrons leak out of nuclei; Tree drip line, the area defined by the outermost circumference of a tree canopy where water drips from and onto the ground, useful for tree crown measurement; Drip irrigation line, where the tubes and hoses are laid

    Beyond the proton drip line along the upper right, nuclides decay by proton emission. Drip lines have only been established for some elements. Drip lines have only been established for some elements. The island of stability is a hypothetical region in the top right cluster of nuclides that contains isotopes far more stable than other ...

    en.wikipedia.org/wiki/Semi-empirical_mass_formula

    A dashed line is included to show nuclides that have been discovered by experiment. The difference between the energies predicted and that of known binding energies, given in kiloelectronvolts. Phenomena present can be explained by further subtle terms, but the mass formula cannot explain the presence of lines, clearly identifiable by sharp ...
