This chapter provides the Three-Phase Model as risk management technique. With this model, a manager can come to grips with the situation in which an organization finds itself, or in which various of its sub-components are situated.

A few of the foams mentioned in Chapter 4 contained suspended solid particles in addition to the two essential phases, that is, a dispersed gas and a liquid medium. Foams, in which a third (solid) phase is highly important, are used on a large scale in froth flotation. This procedure is employed to separate valuable (say, A) from unneeded minerals (say,

Experimental studies on FEs and related materials show that they are characterized by various heterophase states. Amongst the heterophase states that have been studied in the last decades, the three-phase states are of particular interest for a number of reasons.

The sinusoidal waveform, at a given frequency, is characterized by its amplitude and phase. In a single-phase source we studied so far, it is assumed that a sinusoidal wave is the input. However, keeping the amplitude the same, a source with three sinusoidal waveforms differing in equal amount of phase turns out to be better for electric-power ...
