In the first part of the data analysis, we used IBM PASW Statistics 18 for descriptive statistical analyses, and the data were presented as means (standard deviations), percentages, medians, and minimum and maximum values, where appropriate.
Continuous variables were expressed with mean, standard deviation, and minimum-maximum values where categorical variables were reported as frequency and related percentage.
The process of HDI determination consists of choosing upper and lower parameters for each indicator and the normalization is given by an equation that measures the distance between the observed value for the indicator and the minimum value as a proportion of the distance between the maximum and minimum value where I = (observed value-minimum value)/(maximum value-minimum value).
Consequently, the function has a single maximum value at, where (2.34).
Let and, respectively, be the minimum and maximum value of, where the points in have been neglected.
The maximum Coulomb failure stress attains a maximum value when β = 1/2 arctan (1/µ), where β is the angle between the direction of the maximum compression and the fault plane orientation (Fig. 4).
At Ra = 104, the maximum Nu number occurs at about 40°, and at Ra = 106, the Nu number attains its maximum value at 26°, where 0° denotes a differentially heated enclosure. .
(b) holds for x that is less than or equal to the maximum value x 0 where all the spherical caps do not overlap, as shown in Figure 3.
To avoid bias for the few patients with extremely long observation times, the time under risk was truncated at a fixed maximum value (17.5 years) where at least 10 patients of the cohort were still at risk.
