    Verify the depth z below the uniformly loaded area where the stress increase is to be obtained. Plot the plan of the loaded area with a scale of z equal to the unit length of the chart (AB). Place the plan on the influence chart in such a manner that the point below which the stress is to be determined in located at the center of the chart.

    The source free equations can be written by the action of the exterior derivative on this 2-form. But for the equations with source terms (Gauss's law and the Ampère-Maxwell equation), the Hodge dual of this 2-form is needed. The Hodge star operator takes a p-form to a (n − p)-form, where n is the number of dimensions.

    en.wikipedia.org/wiki/Special_number_field_sieve

    In number theory, a branch of mathematics, the special number field sieve (SNFS) is a special-purpose integer factorization algorithm. The general number field sieve (GNFS) was derived from it. The special number field sieve is efficient for integers of the form r e ± s, where r and s are small (for instance Mersenne numbers).

    en.wikipedia.org/wiki/Periodic_annual_increment

    In forestry, periodic annual increment (PAI) is the change in the size of a tree between the beginning and ending of a growth period, divided by the number of years that was designated as the growing period. [1] For sigmoid growth, the graph of PAI increases rapidly and then quickly declines, approaching zero. PAI may go negative if a tree ...
