[2] His M.Sc. thesis was entitled Electrical characteristics and theory of operation of a dry electrolytic rectifier (1926). In his doctoral studies he worked on analog computers with Vannevar Bush, developing the ... WebThe Higbie penetration model for mass transfer compensates for transient behavior. It assumes that mass transfer occurs during brief phase contacts that do not allow enough time for steady-state conditions. In other words, the phases collide but do not have a definitive and continuous interface with respect to time.
