In this paper, we propose an optimization approach that can simultaneously determine the four major aerodynamic coefficients of road tunnels: the friction coefficient of tunnel wall, the averaged drag coefficients of small-sized and large-size vehicles, and the pressure-rise coefficient of jet fans.
In the study, the sodium void effect and the major feedback coefficients are analyzed.
The optimization method employs Genetic Algorithms which make use of a full Navier-Stokes solver for accurate estimation of major aerodynamic coefficients in the evaluation of the objective function.
Additionally, the metric to measure the co-expression falls into one of two major categories: correlation coefficients or mutual information measures [ 19].
While energy density is very sensitive to turbine efficiency (sensitivity coefficient in excess of 0.60), it is relatively insensitive to all other major design parameters (sensitivity coefficients < 0.15) like compressor efficiency, inlet water temperature, scaling methodology, etc.
The measurement of partition coefficients show major differences within the sulfated mimetics as well as between the measured and calculated log P values.
Moreover, all of the major ions have high coefficients of variations (Table 1), indicating that the hydro-chemical compositions of the samples show a high variability among the study area.
For instance, even if the local branches keep their own production techniques unchanged (heterogeneous), as long as the proportions of their production to the total production change, the aggregated coefficients in major cities still may significantly fluctuate.
In this paper, we develop the partially penalty immersed finite element (PIFE) method with the Crouzeix-Raviart type polynomial spaces to solve the anisotropic flow models in which the diffusion coefficient is a piecewise definite-positive matrix, although we consider isotropic elliptic problems with piecewise scalar coefficients in major length for simplicity.
In models with categorical or binary dependent variables, unobserved heterogeneity can be a major problem because the coefficients (and subsequently odds ratios) are not only determined by the relation between the dependent und the independent variables, but also by the variances in the unobserved heterogeneity.
