However, because such models are significantly less sensitive than dispersion models to the contributions of one or a few sources, as well as to the interactions among sources that are widely distributed geographically, if you wish to use a grid model, you should consult with the appropriate EPA Regional Office to develop an appropriate modeling protocol.
Current literature contains multitude of reports studying the epithelium turnover process [6], [7], [8], [9], [10], [11], [12] by using either a grid model [13], lattice-free model [7] or discrete multi-compartmental model [9].
In previous work, we have developed a concept for up-scaling pore-scale molecular diffusion coefficients using a grid-based model for the sample pore structure.
The importance of adequately modeling the floor slab is highlighted and the often employed approach of using a grid of beams to model the slab system is shown to be impracticable for simulating collapse within the APM framework that involves the removal of column elements.
Fig. 5 Best source model inferred by strainmeter data using a grid search (see Table 1, Model (3) for details).
We developed an atom-based 3D-QSAR model by using a grid spacing of 1.0 Å and a maximum PLS factor of four.
We extend this approach in two ways: (1) using a grid-based landscape model, as described above, thus obviating the need for discrete waypoints, and (2) taking into account not only the divergent part of trajectories, but also the length of the shared part.
Tsuchiya et al. (2005) examine the economic effect of 2004 Chuetsu Earthquake with a Spatial Computable General Equilibrium (SCGE) model and Yamano et al. (2007) attempt the same using a regional grid model.
The 3D lithofacies architecture of the thrust-imbricated Paleoproterozoic 85.5 Mt Flin Flon volcanogenic massive sulfide (VMS) ore system, Trans-Hudson orogen, Canada has been mapped in 3D using a numerical grid modeling methodology.
However, predicting inundated area in floodplains using a sub-grid model has not been rigorously validated.
