✦ Synopsis

A correlation has been proposed for the transport of gases through insoluble monolayers in the form of Equation (1). This equation is applicable to an area coverage below 32A.2/molecule of the monolayer and when interactions among molecules of water, gas, and monolayer may be neglected. Therefore, it is suggested that the correlation should be applied only to slightly soluble gases and at high surface pressure of the film where the monolayer molecules are highly compacted. If information is available on the molecular size of the monolayer, then the actual void area in the film can be calculated. By also taking into consideration the interactions among molecules, we may very well be able to correlate all the systems by a single equation. However, this can be done only after the structure of the monolayer molecules and their interactions with water and gas are fully understood.

A method is proposed to solve fixed end-point, linear optimal control problems with quadratic cost and singularly perturbed state. After translating the problem into a two-point boundary value problem, we choose two points t1, t2 E [ t o , tf] and let 7 = ( t -~o ) / E and u = ( t ft)/e. The ~s c a
