Hypsicity

As an example, Scheme 4.10 and Table 4.8 summarize the hypsicity analysis for the Craig plan. Hypsicity indices for all plans are given in column 8 of Table 4.7. Figure 4.34 illustrates the change in oxidation level profiles as a function of reaction stage. It turns out that the Campos plan with the highest RME is also the one with an HI closest to the isohypsic condition of HI = 0. In Table 4.8 a check on the computation of 2 made by taking... [Pg.125]

A parameter that tracks the oxidation length traversed over the course of a synthesis plan equal to the absolute value of the sum of all the ups and downs in a hypsicity profile or bar graph beginning with the zeroth reaction stage. [Pg.87]

For monotonic increases (hypohypsic profile) or monotonic decreases (hyperhypsic profile). lUDI is twice the height of the first bar in the hypsicity profile (see Figure 5.5 for verification). [Pg.105]
