✦ Synopsis

Here, it is shown that the ''traditional approach'' to variable bubble-point problems, using black-oil models, is not consistent, because it violates the ''bubble-point conservation law.'' In order to have a consistent approach, it is necessary to incorporate shocks-discussed in previous papers-in which the bubble-point is discontinuous. A ''consistent approach'' is applied to specific examples, and results compared with those of the ''traditional'' one. The conclusion that the ''traditional approach'' generally yields large errors for the production rates and other parameters of interest in the oil industry, is reached.

An effective way to extend to the multi-input case the variable structure control philosophy is the method based on a set of m#1 control vectors forming a simplex in RK, and on the corresponding switching of the controlled system from one to another of m#1 different structures.

A theoretical discussion is presented for the separation attainable via adsorption at the surfaces of bubbles rising up through a liquid solution. This heretofore neglected operation, which is culled bubble frocfioncition, differs from both foam fractionation and gas desorption.

The aim of the present paper is to make use of the modern theory of point processes to study optimal solutions for single-item inventory. Demand for goods is assumed to occur according to a compound Poisson process and production occurs continuously and deterministically between times of demand, suc
