A more optimistic cost number would be about $10 billion per person using the current model based on extrapolation from moon landings, he said.
It is therefore a predictive model, based on the extrapolation of past variations.
In addition, climatic conditions were obtained for each population of origin (Additional file 3: Table S3), using an extrapolation model, based on 1971 2000 measurements from nearby weather stations, and implemented in BioSIM [ 86, 87].
Though an optimized splitting positive definite mixed FE extrapolation (OSPDMFEE) model based on the POD technique for the 2D viscoelastic wave equation is developed in [27], it has three unknown functions and the OSPDMFEE model has more degrees of freedom than the current OFEE format, so that its theoretical analysis and numerical simulations have more difficulties than the current OFEE method.
Choi et al. [7] developed the AZRED model based on an experimental data filled lookup table with interpolation or extrapolation for inputs not in the table to model both imperfect mixing at crosses and Double T-junctions.
For instance, models based on linear extrapolations of V P-ρ relation argue for about 2 wt% silicon alloyed with iron in the inner core (Badro et al., 2007; Antonangeli et al., 2010), while a recent model using a power law for the V P-ρ extrapolation leads to 8 wt% silicon (Mao et al., 2012).
Since 2014, the reduced-order extrapolation MFE models based on POD for the 2D hyperbolic equations, unsteady parabolized Navier-Stokes (NS) equations, and viscoelastic wave equation have been proposed by Luo's team (see, e.g., [22 24]) to avert the vain reduplicated calculations.
Variation in street-level noise with regards to vehicle traffic and road proximity has been explored, [ 18] but most studies on traffic noise have relied on modeling of noise levels from a network of roads, land use regression, or extrapolation of models based on a small number of noise samples [ 22- 24].
Both approaches gave very similar results, which are as similar or different as are predictions resulting from extrapolation with PBPK models based on different published sets of parameter values for children (Table 1 ).
Estimates of mortality rates are based on data from vital registration systems where possible, and from other available data and model-based extrapolations elsewhere.
While doubtless imperfect, plausible model-based extrapolations such as a recent one from America's Centres for Disease Control and Prevention CDCC) suggest, in the absence of intervention, that there could be 1.4m cases in west Africa in the next three months.Not that Ebola will necessarily be contained in west Africa.
