Evaluation meaning

At the same time, we remark that if we estimate the difference between the two undertaken fittings in terms of statistical moments, the deviations that occur are rather moderate. Indeed, evaluating mean volume and mean-square volume from formulas using the numbers from Table I (entries 1 and 2), one gets for the... [Pg.468]

Evaluation of Eq. (66) with the spectrum Eq. (83) is shown in detail in Stepisnik (1993, 1994). For the narrow pulse and the finite pulse PGSE experiment, two relatively simple closed form expressions are obtained. Figure 2 shows the fit of evaluated mean-squared displacement to the experimental data (Grinberg et al., 1987). [Pg.347]

Tricyclic derivatives of types 205, 248, and 270 contain an active methylene group attached to the carbon atom of the imine moiety. To determine the relative reactivity of the active methylene group, deuteration experiments with deuterium oxide were carried out on the hydrochloride salts of 95, 203, 283, 306, 375, and 376. The results were evaluated means of H-NMR spectroscopy. " The deuteration rates k were ... [Pg.356]

When the body of Fischer assay data on the K-series samples is evaluated, mean values for the weighted averages of these cores are 10.3 and 11.9 gal/ton for Sunbury and Cleveland HGZ, respectively. Coefficients of variation of 8.2% (Sunbury) and 6.9 0 (Cleveland HGZ) were observed with a total range of assay values ranging from 5.4 to 18.4 gal/ton. Current data for some... [Pg.173]

The symbol + means a positive evaluation - means a negative evaluation means medium validity or a conflicting situation. [Pg.79]

Follw-up Studies. The results of the Tarrant and Allard study (9), combined with an incident in which several dead snowshoe hares with elevated levels of As (more than 100 ppm in various tissues) were found in a treated area, prompted an intensive effort to further elucidate patterns of applicator exposure and to evaluate means of reducing exposure to humans and other animals. [Pg.112]

The term evaluation means risk assessment, inspection, or risk assessment and inspection. [Pg.948]

The method was illustrated by application to the Isotopic COs (38) (Table JL), Friedman and Kimel (39) also evaluated mean square torques for CO In the liquid phase but their calculated values are much smaller than those derived by Gordon from measurements of the third and fourth moments of IR and Raman spectra. The most likely reason for the discrepancy is that Friedman s assumption of a spherically symmetric external force field for CO Is not justified. [Pg.112]

The various study and evaluation means of this phenomenon can be summarized in various levels of importance, but they are not exclusive to one another ... [Pg.158]

The maintenance activities shall be based on risk evaluation, meaning that the activities shall be seen in light of the probability for and the consequence of the incidents they are intended to control. [Pg.384]

This is the case with the evaluated mean activity coefficients tabulated by Goldberg (Z5). The activity coefficients were listed to 23.193 roolal and values were given for the parameters of the equation to which the activity coefficients were fit ... [Pg.403]

Owing to the gradual increase in the avaUabUity and capacity of computers, it is becoming more and more convenient and feasible to fit an analytical function to the experimental particle size distribution data and then handle this function mathematically in further treatment It is for example very much easier to evaluate mean sizes from analytical functions than from experimental data. Apart from the many curve-fitting techniques available, use can also be made of special graph papers which exist for many of the common... [Pg.42]

Integral evaluation means that the measured data are compared with the integrated form of the rate equation, for example, for a constant volume first-order... [Pg.381]

Collecting data for statistical process control (SPC) to evaluate mean time between failures (MTBF), cost of maintenance, failure rates, and so on... [Pg.27]
