Fig. 1 shows a block diagram of a regulated adaptive process. The method makes a hypothetical material. Its regulation is disturbed by an exogenous material of exactly the same composition (see Peper 2004b). The diagram comprises the digestive tract, the bloodstream, the process, the procedure regulator and an adaptive regulator. When the exogenous material alterations the level of your material from the bloodstream the adaptive regulator right for this disturbance by readjusting the output level of the procedure.
