It is straightforward to see that the relative surface coverage of the respective phases can be conveniently determined by image analysis, such as bearing analysis, in the illustrative examples shown above (see also Chap. 2). In addition, one can investigate the often crucially important interface region between the phases (Sect. 3.4.5). 

We shall see that there are certain generic features of the thin-film approximation that have already been illustrated by the journal-bearing analysis, which will appear whenever the thin-film approximation is used. The most significant feature of the journal-bearing analysis, which is shared by all thin-film theories, is the assumption that velocity gradients in the direction parallel to the boundaries are asymptotically small compared with those... 

Work to date has resulted in evolving designs for all three blowers, as shown in Figures 1, 2 and 3. All three designs utilized a typical turbo-machine design process that included tasks such as specific speed analysis, blade optimization, rotor-dynamic analysis, bearing analysis, thermal analysis, and motor optimization studies. Each machine has been...

Masonry plates help to more uniformly distribute loads from a bearing to supporting concrete substructure elements below. Additionally, they provide platforms to facilitate maintenance and repairs of bearings. Analysis shows that a steel masonry plate will deform under concentrated bearing loads (Stanton 1999). This potential deformation, which tends to cause a dishing effect because of the relatively flexible... 

Two-layer LB films following the treatment in water or aqueous electrolyte solutions were investigated by AFM. Besides the representative three-dimensional images the cross-sections of the layer are also displayed. The surface of the LB film treated in water (Fig. 2) seems to be rather smooth with some holes or hollows of various sizes. From the bearing analysis two depth levels can be identified with a difference between them of about 5.4-5.5 nm. That value is quite close to the thickness of the cadmium arachidate bilayer (5.6 nm), so the depth levels can be supposed to correspond to the bare substrate and to the top of the two-layer LB film. The coverage of the substrate was proved to be more than 90% by calculating it from six images recorded at different areas on the sample.

The program used for this design work incorporates finite difference forms of the Reynolds and energy equations for the oil film, plus closed-form equations for the pressure and thermal distortions of the pad. These are all iteratively related, including factors to compensate for the carryover of heat from pad to pad. This program was first written in the raid 60 s and has been revised numerous times since then to incorporate advances in bearing analysis and to include empirical correction factors from test results.
