During earlier work al Physics International and the Kurchatov Institute and Sandia Laboratories, a solution to the problem of power concentration was demonstrated, again beyond the scope of this article. See also Fig. 4. 

Avrami et al (Ref 46) used an electrode beam app (Physics International Mod 738 Pulserad) to rapidly heat a slab of Al. The shock thus generated by rapid energy deposition was transmitted into pressed pellets of KDNBF (K dinitro-benzfuroxan). With shocks of about 0.2 microsec duration and a pellet thickness of 0.25 inch the initiation threshold measured was about 18 kbar... 

The only assumption therefore is that the Maxwell vector potential A exists in the physical internal space of 0(3) symmetry. The gauge-invariant Lagrangian (205) can be developed as...

Auger electron spectroscopy with depth profiling via argon ion etching (position and thickness of near-surface layer), transmission electron microscopy of ultramicrotomed cross-sections (physical internal structure), elemental analysis (extent of metal salt conversion), and surface electrical resistivity versus temperature profiles (continuity of near-surface layer). The data from these techniques were used cooperatively to develop a model for these microcomposite polyimide films. The model represents the sample as three distinct regions. Fig. 1. The bulk of the film contains either converted (e.g. Ag) or nonconverted (e.g. C0CI2) additive in a predominately polyimide environment. An oxide-rich (e.g. 0 ) or metal-rich layer (e.g. Ag, Au) interspersed with polyimide accounts for the second region.

Existence of two extreme phases in the polymer is assumed. The diagram represents a polymer in the glass tiansition state with a predominant active phase (b) In the 1-D model, the frozen fraction (pf = Lf (T) /L(T) is defined as a physical internal state variable that is related to the extent of the glass transition, (c) Frozen fraction, (j>f (T), as a function of temperature, derived from curve fitting of the modified recovery strain curve divided by the predeformation strain, (d) Prediction of the free strain recovery responses during heating for polymers predeformed at different levels.

While the physicists failed to validate their models and therefore could not be certain that they caught the right processes their efforts were still seen as useful to the control project by the consultancy. Although the models fell short with regards to physics internal assessment criteria such had no consequences for the models usefulness to the control project. The fact that the control project used the physicists models, despite their inability to validate them, shows that the usefulness to process control -criterion required significantly less representational accuracy and certainty than that aimed for by the physicists. The domain of work in which the physicists representational modeling formed part, was engineering of process control that operated after a unique set of success criteria that were based on operational usefulness and impact on production yields. ...
