Design array

As another example of the reduction in the number of runs, consider an experiment to investigate three design and four environmental variables, all at three levels. A Taguchi crossed array might use a 3 fractional factorial design for the design array and a 3 fractional factorial design... 

Some of these differences reflect different philosophical approaches to data analysis. Taguchi s analysis of robust design experiments is frequently conducted in terms of a performance statistic, such as a signal-to-noise ratio, that is calculated for each point of the design array using data obtained from the environmental (noise) array about that point.

Feed water source also influences the design array of the RO unit. This is because the feed water flow and concentrate flow rates are also determined based on feed water quality. Higher feed water quality allows for higher feed flows and lower concentrate flows to be employed. Higher feed water flows and lower concentrate flows reduce the number of membrane modules required in the RO system. 

The magnetic field inside a superconducting solenoid is not particularly homogeneous, and compensation of the field gradients is quite a complex problem that has been solved49 by the provision of mathematically designed arrays of superconducting or normal, resistive shim-coils, or both. 

Second, the implementation of designed arrays of 2-D colloidal crystals immobilized on a polymer was demonstrated. Two sets of gratings were formed... 

Furthermore, the surface waves here are not related to the well-known surface waves that can exist on infinite arrays in a stratified medium next to the elements. These will readily show up in PMM calculations. These are simply grating lobes trapped in the stratified medium and will consequently show up only at higher frequencies, typically above resonance but not necessarily so in a poorly designed array. In contrast, the surface waves associated with finite arrays will typically show up below resonance (20-30%) and only if the interelement spacing is <0.5)t.
