Draft: More complex graph computations for undirected graphical models by the CoCo bundle for R

An auto flow controller which may be used to automatically release a number of component liquids which are to be transmitted to a mixing tank without constantly having to replenish the liquid component chemicals. A sensor located in a mixing tank is equipped with sensors which commands a set of storage containers to release a predetermined quantity of liquid component chemical. This quantity may be controlled by use of level graduated sensors which control pumps or solenoids or by means of a single sensor which initiates timer equipped pumps or solenoids. A combination of these methods may be used. Pump feed, gravity feed or combination of both are utilized.
