Figure 15.3 shows the results of the second SEM analysis designed to give a qualitative determination of the depth of fluorination. A carefully prepared cross section of the O-ring was analyzed using the so-called mapping technique. The light streak across Picture 3.2 shows where the fluorine is concentrated. With the aid of the microscale shown it can be estimated that the fluorination is approximately 5 pm deep. [Pg.236]

It may be possible to use Geographic Information Systems (GIS) to map biomonitoring results to determine whether there is a spatial pattern in exposure concentrations. This could be overlaid with GIS maps of environmental data (for example, air or water pollution or distribution of waste sites) to determine whether biomonitoring results correspond to specific environmental sources. However, mapping techniques are generally not useful for sporadic, localized sources such as food or consumer products. In such cases, survey questionnaires and sampling of the home environment are of more direct use in understanding exposure sources. [Pg.207]

The success of the simulation depends on your ability to describe the process in sufficient enough detail to produce realistic results. You can derive this information from a Process Map or Value Stream Map (Technique 46). Be sure to include key subprocesses, decision points, and queues (waiting lines). [Pg.249]

Xu and Miu determined the contents of alcohol and many other chemical parameters in beer samples and classified them by using the PCA and nonlinear mapping technique [18]. This data set is processed by PP PCA and SVD. The results is shown in Figure 7. One sample (No.l7 ) which was first classified into plain beer by the manufacture is classified into imperial one. The beer expert s further examination confirmed this classification. PP PCA compared favourably with the traditional SVD algorithm and was at least as good as the nonlinear mapping technique. [Pg.175]

The application of Co XAS techniques to organocobalamins and their models has been reported. Several of the results appear controversial, with a very recent (2001) methodological study presented that explains the origin of the controversies. " Proposals to improve EXAFS structure-parameter refinement by first-shell filtering, and the importance of mapping techniques in this regard, have been described. [Pg.684]

In this section we describe our recent progress in nanomechanical analysis to make it applicable to conditions where we cannot ignore the adhesive and viscoelastic effects, and where JKR contact plays an important role, as explained in Section 3.3. Then we discuss the realistic applicable limit of this theory based on several experimental results. Furthermore, the viscoelastic effect is treated experimentally and theoretically to some extent, with the future goal of making nanomechanical mapping a nanorheological mapping technique. [Pg.148]

The well-established elastic-predictor/plastic-corrector return mapping algorithm can be utilized to obtain the inelastic responses of the microscale amorphous and crystalline phases. Here, we only outline the steps to be used. A detailed description of this solution algorithm can be foimd in References [103] to [105]. The return mapping technique is capable of handling both associative and nonassociative flow rules with variant tangent stiffnesses and results in a consistent solution approach [105]. It is noted that this algorithm is applicable to the material, intermediate, or spatial formulations. [Pg.193]
