However, it is difficult for the fitting of the variation function to reflect the spatial variation law of the geological conditions (the variation law of sedimentary facies and the spatial distribution of channel sand bodies, etc).. Therefore, based on the modelling of the sedimentary facies, this modelling is constrained by geological experience in removing the singular values.
The proposed reordering is related to the Gestalt laws of pattern visual perception [14], and more specifically to the spatial proximity law.
Production traits and hormone and metabolite concentrations were analyzed by repeated measures using the MIXED procedure with days as the repeated effect and first-order autoregressive (for evenly spaced data) or spatial power law (for unevenly spaced data) as the covariance structure.
Reorganization of rows and columns of a matrix does not modify data but may ease or impair visual analysis of data similarities in this structure, according to Gestalt spatial proximity laws.
Once the domain of macroecologists, spatial scaling laws have recently been advanced for the microbial majority and are providing powerful, scale-invariant models of local-to-global distributions of key biodiversity metrics (Fenchel and Finlay 2004; Green and Bohannan 2006).
Temporal as well as spatial power-law correlations were observed and their significance was discussed.
Based on thoroughly geomechanics tests around the group of chambers, the spatial characteristics and law of the stress distribution around the chambers were studied, the characteristics of chamber deformation and damage were also researched.
A new algorithm is developed here for Monte Carlo simulation of turbulent diffusion with random velocity fields having a power law spatial spectrum, arbitrarily many statistical scales, long range correlations, and infrared divergence.
(We use cross-parenting in preference to cross-breeding, the term common in biology, as it has a greater connotation of voluntary choice. Note too that the term population mixing in our context differs from its definition in epidemiology where it refers to contacts among people as a result of spatial movement; see Law et al. 2008).
The temporal variations of the phase and the intensity of the received signal provide information on the spatial spectrum (power law) of density inhomogeneities, the anisotropy of inhomogeneities, the inner turbulence scale, and the bulk velocity of plasma (Patzold et al., 1996; Imamura et al., 2005; Efimov et al., 2010).
