It is argued that Markov models and auto-regressive models, generally used for synthetic wind speed data generation, do not contain sufficient low-frequency information related to seasonal and diurnal patterns.
The experimental semivariograms were fitted to various theoretical models generally used in earth sciences, such as spherical, exponential, and Gaussian models (Mehrjardi et al. 2009).
In this situation, close to the emission and height of the emission, Gaussian models generally used to predict the behaviour of atmospheric releases are not well adapted.
The capability to implement model in a GIS environment has anticipated rise in the number of models, generally used to predict soil loss, sediment yield, nutrient loss, pollutant transport in watershed and groundwater movement.
The models generally used to reconstruct past cultural trajectories in the Saharan region often emphasize the concept of 'optimality', represented by wet periods, and tend to link dry intervals with the abandonment of sites or regions.
The comparison of the results proved satisfactory and highlighted the interest of considering a more realistic mechanical behavior of hard rock masses in rock engineering compared with the elastic perfectly plastic models generally used in numerical modeling of underground deep mines.
While built on a sound physical foundation, isentropic, one-dimensional models generally used to analyze the dynamics of dilute two-phase (feed-powder particles suspended in a carrier gas) flow during the cold-gas dynamic-spray process, require the use of numerical procedures to obtain solutions for the governing equations.
Previous experimental evolution studies with viral models generally used either individual populations or homogeneous spatially structured experimental design.
