GSTools v1.3: a toolbox for geostatistical modelling in Python [PDF]

open access: yesGeoscientific Model Development, 2022
Geostatistics as a subfield of statistics accounts for the spatial correlations encountered in many applications of, for example, earth sciences. Valuable information can be extracted from these correlations, also helping to address the often encountered

A parsimonious parametrization of the Direct Sampling algorithm for multiple-point statistical simulations

open access: yesApplied Computing and Geosciences, 2022
Multiple-point statistics algorithms allow modeling spatial variability from training images. Among these techniques, the Direct Sampling (DS) algorithm has advanced capabilities, such as multivariate simulations, treatment of non-stationarity, multi ...

Assessment of uncertainty for coal quality-tonnage curves through minimum spatial cross-correlation simulation [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2018
Coal quality-tonnage curves are helpful tools in optimum mine planning and can be estimated using geostatistical simulation methods. In the presence of spatially cross-correlated variables, traditional co-simulation methods are impractical and time ...

Air velocity spatial variability in open Compost-Bedded Pack Barn system with positive pressure ventilation

open access: yesAnais da Academia Brasileira de Ciências, 2023
In Compost-Bedded Pack Barn (CBP) systems, air velocity is linked with the thermal comfort of housed dairy cattle and bedding quality and, therefore, assessing ventilation efficiency is essential.
