The following study deals with the characteristics of the reaction to form BaSO4 and BaCO3 from Na2SO4 and Na2CO3, respectively, using BaS as the other reactant. These reactions would theoretically increase the efficiency of the chemical recovery process in papermaking to near 100% by completely converting Na2SO4 to Na2S and Na2CO3 to NaOH. Kinetic data were collected, and it was determined tha...

An augmented compact genetic algorithm (acGA) is presented in this paper. It exhibits all the desirable characteristics of compact genetic algorithm (cGA). While the selection strategy of cGA is similar to (steady-state) tournament selection with replacement (TSR), the proposed algorithm employs a strategy akin to tournament selection without replacement (TS/R). The latter is a common feature o...
