Figure 9.

Cause-effect information in a mechanism $\{u_1,u_2\}$ and the partition $\{u_1\}/\{u_2\}$. In both cases, the state is $(1,2)$. The left IF corresponds to the mechanism in Figure 5. There is no integration as the IS of the partition has the same structure. The equations to build the IS and IF of the partition are those depicted in Figure 5 (bottom), but one and two are used instead of $0.5$ and $1.5$ as the constant values for the variables outside each subsystem.
