As a first approximation, the guidelines should point to the appropriate methods that should be used for analysis and will be later refined.
Based on analytical simulation using a simple parallel-plate approximation, scaling guideline is derived in terms of pull-in, release voltage, pull-in time and release time.
Fit statistics chosen for this analysis were the Comparative Fit Index (CFI), Tucker-Lewis Index (TLI) and the Root Mean Square Error of Approximation (RMSEA), with guidelines for appropriate fit being > 0.95; > 0.95, and < 0.08 respectively [ 13].
Along these lines, we decided to use the following indices: the relative chi-square (CMIN/DF), the goodness-of-fit index (GFI), Bentler's comparative fit index (CFI) [ 24], the Tucker-Lewis Index (TLI) [ 25], and the root mean square error of approximation (RMSEA), following the guidelines by Jackson et al. [ 26].
It should be pointed out that in order to understand the object of the study, an initial approximation was sought with the guidelines that guide the Brazilian health system due to its peculiarities.
Although guidelines for facial approximations, including those for the eye, are in use in South Africa, limited data on African populations exist to confirm its validity.
Furthermore, we show that the relations found for the operating, structural and material properties on the basis of these simple configurations can provide design guidelines and first approximations for more realistic process equipment geometries.
Compared to more accurate simulations, these guidelines result in an average approximation error in the transfer functions of 1.3 dB in the third octave band SPLs while considerably reducing the evaluation time.
Categorical data were analyzed in frequency tables that fulfilled the guidelines for " a large sample" approximation and χ2 test was used to test the null hypothesis (e.g. QS producers in mucoid vs nonmucoid isolates).
Based on the cases considered here, we suggest the following guidelines for saline convection: the OB approximation is valid for cases with ερ < 0.05, and the full NOB set of equations needs to be used for cases with ερ > 0.10.
