Scaling factor, measurement

This is defined as the tendency to inhibit emotional responses during a crisis (Roger and Nesshoever, 1987). The scale which measures this concept has four factors, namely ... [Pg.140]

Mole fractions, parts per million, and parts per billion all are ratios of moles of a particular substance to total moles of sample. Mole fraction is moles per mole, ppm is moles per million moles, and ppb Is moles per billion moles. These measures are related by scale factors ppm = 10 JT, and ppb = lO X - In other words, a concentration of 1 ppm is a mole fraction of 10 , and a concentration of 1 ppb is a mole fraction of 10. When the ozone concentration in the atmosphere reaches 0.5 ppm, the mole fraction of ozone is 0.5 X 10 , or 5 X 10. Example shows how to work with parts per million. [Pg.317]

Fitzgerald et al. (1984) measured pressure fluctuations in an atmospheric fluidized bed combustor and a quarter-scale cold model. The full set of scaling parameters was matched between the beds. The autocorrelation function of the pressure fluctuations was similar for the two beds but not within the 95% confidence levels they had anticipated. The amplitude of the autocorrelation function for the hot combustor was significantly lower than that for the cold model. Also, the experimentally determined time-scaling factor differed from the theoretical value by 24%. They suggested that the differences could be due to electrostatic effects. Particle sphericity and size distribution were not discussed failure to match these could also have influenced the hydrodynamic similarity of the two beds. Bed pressure fluctuations were measured using a single pressure point which, as discussed previously, may not accurately represent the local hydrodynamics within the bed. Similar results were... [Pg.69]

Table 2. Scale factors for ab initio model vibrational frequencies adapted from (Scott and Radom 1996). Please note that these scale factors are determined by comparing model and measured frequencies on a set gas-phase molecules dominated by molecules containing low atomic-number elements (H-Cl). These scale factors may not be appropriate for dissolved species and molecules containing heavier elements, and it is always a good idea to directly compare calculated and measured frequencies for each molecule studied. The root-mean-squared (rms) deviation of scaled model frequencies relative to measured frequencies is also shown, giving an indication of how reliable each scale factor is. Table 2.

Fractionation factors for Li-HjO clusters are calculated using ab initio vibrational models, in the gas-phase approximation. Vibrational frequencies in this system are largely unknown, and the few that have been measured are contentious. In the absence of reliable experimental constraints, Hartree-Fock model ab initio vibrational frequencies are normalized using a scaling factor of 0.8964. It is generally thought that aqueous lithium is coordinated to four water molecules (Rudolph et al. 1995). The authors speculate that 6-coordinate lithium in adsorbed or solid phases will have lower Li/ Li than coexisting aqueous LF. [Pg.107]

Since diffraction pattern has a scale factor LI all distances measured on the pattern should be recalculated into reciprocal. Following Zvyagin s notation one measures B k values on the texture pattern, which correspond to reciprocal values Hgoh by... [Pg.131]

If the circle does contain the origin of the polar chart, the distance between origin of the chart and the center of your circle is the actual residual unbalance present on the rotor correction plane. Measure the distance in units of scale you choose in Step 1 and multiply this number by the scale factor determined in Step 6. Distance in units of scale between origin and center of the circle times scale factor equals actual residual unbalance. [Pg.145]

Furthermore, Boukamp and Adler showed that when the electrodes on opposite sides of a cell are different from each other (as they are in a fuel cell), errors may not only involve a numerical scaling factor but also cross-contamination of anode and cathode frequency response in the measured half-cell impedances. For example. Figure 55a shows the calculated half-cell impedance of the cell idealized in Figure 53a, assuming alignment errors of 1 electrolyte thickness. Significant distortion of the halfcell impedances (Za and Zb) from the actual impedance of the electrodes are apparent, including cross-talk of anode and cathode frequency response (1 and 10 Hz, respectively), as well as a... [Pg.597]

GLS preprocessing can be considered a more elaborate form of variable scaling, where, instead of each variable having its own scaling factor (as in autoscaling and variable-specific scaling), the variables are scaled to de-emphasize multivariate directions that are known to correspond to irrelevant spectral effects. Of course, the effectiveness of GLS depends on the ability to collect data that can be used to determine the difference effects, the accuracy of the measured difference effects, and whether the irrelevant spectral information can be accurately expressed as linear combinations of the original x variables. [Pg.376]

EXAFS Data Analysis. A key aspect of the analysis outlined above is knowledge of the correct (k) and for a particular absorber-scatterer interaction. These parameters can either be calculated ab initio (6) or can be determined by measuring the EXAFS of structurally characterized model compounds (7). The ab initio method has the advantage that one need not prepare appropriate models for all possible unknowns. Unfortunately however, the ab initio parameters must be adjusted by a scaling factor and an assignment of E, (8). For this reason, one typically calibrates the calculated... [Pg.31]

These denominators may be regarded as scaling factors by which the clinical, regulatory, ethical or social importance of an ADR may be measured, but they are still inadequate if truly balanced decisions are to be taken. Within these... [Pg.424]

It is noteworthy that from a modeling perspective, 0j is also a scaling factor, since the expectation operator and the variance are of different dimensions. If it is desirable to obtain a term that is dimensionally consistent with the expected value term, then the standard deviation of z0 may be considered, instead of the variance, as the risk measure (in which standard deviation is simply the square root of variance). Moreover, 0i represents the weight or weighting factor for the variance term in a multiobjective optimization setting that consists of the components mean and variance. [Pg.116]
