Furthermore, considering the intrinsic regulation capacity of the frequency and voltage, and the self-synchronization features of a conventional synchronous generator, elaborated model of three-phase virtual synchronous generator (VSG) is established in [10, 11], and such grid interface is widely recognized in three-phase system.
First, a base model was elaborated (Model 1) with only 'year of observation' entered as a fixed effect coefficient.
Three Cox models were elaborated: model 1, presence of PH; model 2, presence of PH, age, sex, body mass index, presence of smoking, diabetes and/or dyslipidemia, and systolic blood pressure; model 3, the covariates in model 2 and extracellular water.
Elaborated model uses two S N curves, i.e. for alternating stress (R = −1) and another one obtained under stress ratio R ≠ −1, for calibrating the equations of boundary condition.
Following the recommendations of Aiken and West (1991), variables were entered into the regression equation in the following order: Simple model - mean age and pubertal status variables; Elaborated model - centered behavioral and circadian measures, and diagnostic status (with controls used as the reference) and, as the final step, the aforementioned interaction terms.
The elaborated model can be then transformed into a model corresponding to the power estimation metamodel.
Much of the power, beauty, and pleasure of models comes from inventing and elaborating models for exploring their implications in new domains (Lave and March 1975).
It is therefore desirable to elaborate models that mimic the clinical situation as closely as possible.
A more elaborated fault model is constructed in the next section.
He elaborated the model in his later work.
PHS, RM, SD and MDVB have elaborated the model, proved the results and written the paper.
