Flexible comparison

The way of using the index is flexible. Comparisons can be made at the level of process, subprocess, subsystem, or considering only part of the factors (e.g. only process oriented factors). Different process alternatives can be compared with each other on the basis of the ISI. Also the designs of process sections can be compared in terms of their indices in order to find the most vulnerable point in the design. Sometimes a comparison based on only one or two criteria is interesting. E.g. a toxicity hazard study can be done by considering only the toxic exposure subindex. Because its flexibility the total inherent safety index is quite easily integrated to simulation and optimization tools.

Part IV showcases three works that use SWTs in engineering settings to solve all three basic tasks discussed above model integration, consistency management, and flexible comparison. We provide a summary of these chapters and discuss how they use SWT capabihties to address the three technical tasks. 

The comparison of both data sources qualitatively shows a similar picture. Regions of high mobflity are located especially between the secondary structure elements, which are marked on the abscissa of the plot in Figure 7-17. Please remember that the fluctuations plotted in this example also include the amino acid side chains, not only the protein backbone. This is the reason why the side chains of large and flexible amino acids like lysine or arginine can increase the fluctuations dramatically, although the corresponding backbone remains almost immobile. In these cases, it is useful to analyze the fluctuations of the protein backbone and side chains individually. 

Figure 9,16 Comparison of theory with experiment for rg/a versus K. The solid line is drawn according to the theory for flexible chains in a cylindrical pore. Experimental points show some data, with pore dimensions determined by mercury penetration (circles, a = 21 nm) and gas adsorption (squares, a= 41 nm). [From W. W. Yau and C. P. yidXont, Polym.

In the absence of more direc tly applicable data, the flexibility factor k and stress-intensification factor i shown in Table 10-54 may be used in flexibihty calculations in Eq. (10-101). For piping components or attachments (such as valves, strainers, anchor rings, and bands) not covered in the table, suitable stress-intensification factors may be assumed by comparison of their significant geometry with that of the components shown. 

A successful application of GA to conformation sampling is, for example, as a part of flexible docking [12-14], It should be noted, however, that none of the three sampling methods discussed above, MD, MC, and GA, was shown to outperform the other two in any general way. In fact, a comparison of the three methods in the context of flexible docking showed similar efficiency for all three [12], although specific advantages are likely to exist for particular apphcations. 

The foregoing comparison of different valve arrangements for both full main air blower trains and TPG trains emphasizes its importance. The range of desired regenerator control, expected modes of operation, and system constraints all influence the choice of valve aiTangements. The selected arrangement depends on safety consciousness, cost considerations, and desired process flexibility. 

In comparison to surface eondensers, contact condensers are more flexible, are simpler, and considerably less expensive to install. On the other hand, surface eondensers require far less water and produce 10 to 20 times less condensate than eontaet type eondensers. 

The VDUs (visual display units) in both control rooms were under-utilized for response to and control of abnormal events, in comparison to other industries. The control room computer had the capability to give the technicians considerable flexibility and power in controlling both productivity and safety factors offshore. However, this power was not utilized.
