The most commonly used method among the multistage designs is a two-stage design.
Figure 3 shows histograms computed by the SSA, Poisson τ-leap and the methods with s = 3, 5. Visual inspection of the plots shows a consistent improvement over the original τ-leap method by means of the multistage RK methods developed here.
To simplify the multistage method reasonably and accommodate the importance of the initial loaded state, we propose a new analytical mechanical model with a vertical wellbore and isotropic horizontal in-situ stresses.
The multistage method 24 takes validation into consideration at each stage of scale development and has been used successfully in previous studies.
The application results of the method show multistage interwell chemical tracing can reflect dynamic variation of fractured parameters effectively, and the monitoring results match with the dynamic production testing results, demonstrating good adaptability of the method.
Analyses were performed using methods that accounted for the multistage, clustered sampling of NHANES III.
CGSS2008 uses the method of multistage random sampling, collecting a sample of 6000 in Chinese mainland with 3982 samples from urban areas and 2018 samples from rural area, which is representative of the national scale.
Using the method of multistage systematic sampling, 596 children aged between 8 and 16 years were randomly selected from severely affected areas of the earthquake.
The solution method was employed to explore the multistage countercurrent cake washing in a segregated and a non-segregated wash effluent circulation.
Herein, a crystallization of mesoporous calcium carbonate nanospheres (CCNSs) with hierarchical structure was prepared by a new facile binary solvent method which is involved in the multistage self-assembly of calcium carbonate crystallites into hierarchical spheres under the templating effect of CO2 (as shown in Figure 1).
