This technique is particularly helpful when the group is in danger of domination by certain participants, or when team members may hold back because of the group makeup. However, if you re looking for more outside-the-box ideas, other ideation techniques may be more powerful, such as Provocation and Movement (Technique 22) or Creative Challenge (Technique 15). 

When you re finished generating ideas, review the list. li you need additional ideas, repeat the steps with a different random stimulus. Or, try another idea generation technique such as Provocation and Movement (Technique 22). 

The Provocative Thoughts you generated in step 3 should have the team thinking outside its normal frame of reference. The next step is to make these PT statements more realistic and feasible by applying one or more movement techniques to each statement. Movement techniques can be categorized as follows ... 

Solving Class 4 problems is what you do when you don t know what you re doing—basic research, where discoveries are made but the path to commercialization is unclear. As such they fall outside the scope of this book—although techniques like Biomimicry (Technique 26), Trend Prediction (Technique 14), Provocation and Movement (Technique 22) and Design of Experiments (Technique 50) can help the Class 4 problem solver. 

Reservoir engineers describe the relationship between the volume of fluids produced, the compressibility of the fluids and the reservoir pressure using material balance techniques. This approach treats the reservoir system like a tank, filled with oil, water, gas, and reservoir rock in the appropriate volumes, but without regard to the distribution of the fluids (i.e. the detailed movement of fluids inside the system). Material balance uses the PVT properties of the fluids described in Section 5.2.6, and accounts for the variations of fluid properties with pressure. The technique is firstly useful in predicting how reservoir pressure will respond to production. Secondly, material balance can be used to reduce uncertainty in volumetries by measuring reservoir pressure and cumulative production during the producing phase of the field life. An example of the simplest material balance equation for an oil reservoir above the bubble point will be shown In the next section. 

The prediction of the size and permeability of the aquifer is usually difficult, since there is typically little data collected in the water column exploration and appraisal wells are usually targeted at locating oil. Hence the prediction of aquifer response often remains a major uncertainty during reservoir development planning. In order to see the reaction of an aquifer, it is necessary to produce from the oil column, and measure the response in terms of reservoir pressure and fluid contact movement use is made of the material balance technique to determine the contribution to pressure support made by the aquifer. Typically 5% of the STOMP must be produced to measure the response this may take a number of years. 

The previous investigations of hard particle transport processes during laser beam dispersing have shown, that the high speed microfocus radioscopy system is a usable arrangement to observe and analyse the movements, velocities and accelerations of particles inside the molten bath. That possibility was, until now, not given by conventional techniques of process... 

Often industry requires fast techniques to measure movements, deformations, etc. The optics methods, between them those based in speckle K gives quick solutions to this problems. 

We have presented a method to analyze the composite displacement and rotation movements. On Tables 1 and 2 we can see the agreement between the experimental values and that obtained from equations (1) or (2). This technique allows to follow the movement in real time, observing directly on the PC screen the ring size and position variations. In this way, we can determine the center and the radius of the ring. 

It has also been shown that sufiBcient surface self-diflfiision can occur so that entire step edges move in a concerted maimer. Although it does not achieve atomic resolution, the low-energy electron microscopy (LEEM) technique allows for the observation of the movement of step edges in real time [H]. LEEM has also been usefiil for studies of epitaxial growth and surface modifications due to chemical reactions.

Shielding and Stabilization. Inclusion compounds may be used as sources and reservoirs of unstable species. The inner phases of inclusion compounds uniquely constrain guest movements, provide a medium for reactions, and shelter molecules that self-destmct in the bulk phase or transform and react under atmospheric conditions. Clathrate hosts have been shown to stabiLhe molecules in unusual conformations that can only be obtained in the host lattice (138) and to stabiLhe free radicals (139) and other reactive species (1) similar to the use of matrix isolation techniques. Inclusion compounds do, however, have the great advantage that they can be used over a relatively wide temperature range. Cyclobutadiene, pursued for over a century has been generated photochemicaHy inside a carcerand container (see (17) Fig. 5) where it is protected from dimerization and from reactants by its surrounding shell (140). 

Photon Correlation Spectroscopy. Photon correlation spectroscopy (pcs), also commonly referred to as quasi-elastic light scattering (qels) or dynamic light scattering (dls), is a technique in which the size of submicrometer particles dispersed in a Hquid medium is deduced from the random movement caused by Brownian diffusion motion. This technique has been used for a wide variety of materials (60—62). 

In the apphcation of dyes three techniques are used the dye Uquor is moved as the material is held stationary, the textile material is moved without mechanical movement of the Uquor, or both move. 

One of the most important material-handling techniques in the chemical industry is the movement of material suspended in a stream of air over horizontal and vertical distances ranging from a few to several hundred feet. Materials ranging from fine powders through 6.35-mm (lA-in) pellets and bulk densities of 16 to more than 3200 kg/m (1 to more than 200 Ib/ft ) can be handled. A large, capable manufacturing...
