Hoffman equation
Nettet24. apr. 2024 · Modeling his learning, L, as percent of mastery, we can write the differential equation L ′ = k(100 − L) Solving as we did in the previous example, we obtain L = Ae − kt + 100. Since he started not knowing any of the codes L(0) = 0, so 0 = Ae − k ( 0) + 100, so A = − 100. Using that Jim mastered 70 of the codes in 4 days, L(4) = 70, so NettetThe equation is expressed as Values of γ varies from 0 to 1; for metals the γ values are in the range 0.4 to 0.8. If γ = 0.5, the Walker equation is reduced to SWT criterion. With the adjustable fitting parameter γ, Walker equation gives superior results.

The Lauritzen–Hoffman plot (right) models the three different regimes when (logG) + U*/k(T-T0) is plotted against (TΔT) . It can be used to describe the rate at which secondary nucleation competes with lateral addition at the growth front among the different temperatures. This theory can be used to help understand the preferences of nucleation and growth based on the polymer's properties in…
