Scanning visualization

However, the described method is labor-intensive and time-consuming since the ring section has to be scanned visually through the microscope to search for the maximum stress value. In addition, the results veiy much depend on the operator s skills and are therefore subjective. Gage R R studies have shown that the practically achievable reproducibility is significantly below the desired level. 

The interim examination and maintenance cell is a shielded hot-cell complex that conducts nondestructive examinations of test assemblies and core components under controlled argon-atmosphere conditions. (Its location is shown in Fig. A.l). The hot cell can also be used to perform limited maintenance of plant equipment or to prepare plant equipment for transfer to other maintenance facilities. The cell contains equipment necessary for disassembly, reassembly, and requalification of test assemblies and components. Nondestructive examinations that can be performed include dimensional checks, weighing, gamma scanning, visual inspections, and photography. Sodium removal facilities are also included. 

Finally, the multiple visualization used by the P-Scan allows to have available A, B, C and D-Scans to the screen representation. 

A-scans with a visual evaluation by the tester to be of little significance. New measuring-data-evaluation-procedures were needed to place additional information at the testers disposal. 

Templates for each of the joint configurations are stored within the system. The operator selects one of the templates, and is provided with a visual representation, as shown in Figure 3, on which he can alter the Joint dimensions and weld geometry to match those of the item to be examined any ae-cess restrictions can also be defined. Using information from a database of available probes, along with the examination level required, ProcGen then calculates the set of scans required (see Figure 4). 

After setting up the test system, the inspeetor can fully concentrate on scanning the test zones. In the case of coupling failure, an acoustic alarm horn will sound and a visual alarm message will appear on the PC display. 

Otlier fonns of microscopy have been used to evaluate nanocrystals. Scanning electron microscopy (SEM), while having lower resolution tlian TEM, is able to image nanoparticles on bulk surfaces, for direct visualization of... 

In addition, as mentioned before, the visual identification of the spot width is also open to considerable error but, if the plate is scanned, and the elution curve obtained, then both the peak width (w) or the peak width at the base (wb) can be obtained fairly accurately (assuming appropriate software is available). 

Visually, failure was mostly eohesive within the adhesive (see Figs. 34 and 46). However, there was a small area of apparent interfacial failure ( initiation zone ) located at one end of each substrate. Line scans were eondueted aeross the initiation zone, from the edge of the substrate to the area of cohesive failure within the adhesive. From the line scans, it was apparent that there were patehes of polymer present in the initiation zone, even when failure appeared to be interfaeial (see Fig. 46). SIMS images of the initiation zone were constructed for various mass numbers (see Figs. 47-49). The images showed well-defined cation-rieh... 

Note In the case of HPTLC plates the detection limit for the visual recognition of the violet = 530 nm) colored chromatogram zones was 20 ng per chromatogram zone. With the exception of the two tetrahydrosteroids the cor-ticosteriods could be detected on TLC plates with fluorescent indicators by reason of fluorescence quenching (Fig. 1 A). Figure 2 illustrates the absorption scans of the separations illustrated in Figures 1A and 1B.

Colorimeter Also called color comparator or photoelectric color comparator. An instrument for matching colors with results about the same as those of visual inspection, but more consistent. Basically the sample is illuminated by light from the three primary color filters and scanned by an electronic detecting system. It is sometimes used in conjunction with a spectrophotometer, which is used for close control of color in production. 

Limitations are obvious if the diseased tissue does not differ from normal tissue or successfully treated tissue in respect of the above-mentioned criteria. Under these conditions, even a contrast agent with high absorption of X-rays is of no help. Another drawback is the short-lasting contrast which requires repeated injections if the diagnosis is missed during the first scan or if persistent visualization of a lesion is required during an interventional procedure. 

Scanning acoustic microscopy (SAM) is a relatively new technique which broke through in the mid-seventies and was commercialized recently. The SAM uses sound to create visual images of variations in the mechanical properties of samples. The ability of acoustic waves to penetrate optically opaque materials makes it possible to provide surface or subsurface stmctural images nondestmctively, which might...
