Finally, the HawkRank scoring function was derived by determining the most optimal weights for five energy terms based on the training set.
Subject to the constraints of total sample number, test termination time as well as the stress region, an optimum constant-stress ADT plan is derived by determining the combination of stress levels and the number of samples allocated to each stress level, when the degradation path comes from inverse Gaussian (IG) process model with covariates and random effects.
Bedrock ages were derived by determining the geologic classification of the bedrock (e.g. Phanerozoic complex, Mesozoic complex) using the Global GIS Database v. 6.2, U.S. Geological Survey, Flagstaff, AZ, USA (www.agiweb.org/pubs/).
This estimate was derived by determining the type and frequency of visit or service, applying the appropriate unit cost for each and multiplying it by the proportion of inpatients using that service.
Volumes were derived by determining the 'numbers of units per patient' and the numbers of patients at each stage in the process: first screening, then start therapy, first year and finally all subsequent years of the simulation.
An estimate of the incidence of PCP in a particular AID was derived by determining the number of cases of PCP in a particular AID per 1,000 hospitalisations with the said AID per year.
A population heart rate-corrected QT interval (QTcN) was derived by determining the exponent δ of the relationship: QT ~ (1000 / RR)δ (where δ is the regression effect of the covariate) using a linear mixed model on log-transformed RR and QT data (measured in ms).
The BAT value was derived by the German Research Foundation and determines the highest acceptable concentrations of substances at the workplace [ 37].
The integer score was derived by assigning points to these factors and determining total scores.
In addition, a simple and explicit formula for optimally determined macroscopic conductivity is derived by solving a nonlinear minimization problem.
