Stochastics of bedform dimensions [PDF]

open access: yes, 2005
Often river dunes are considered as regular bed patterns, with a mean dune height and a mean dune length. In reality however, river dunes are threedimensional and irregular features that cannot be fully described by their mean values.

Application of Weighted Semivariogram Model (WSVM) based on fitness to experimental semivariogram on estimation of rainfall amount

open access: yes, 2011
Abstract. This study presents a weighted semivariogram model (WSVM) which is intended to reduce the uncertainties in the selection of the best-fit semivariogram model and associated parameters. The proposed WSVM is based on the combined forecast method, providing the weighted average semivariogram by summing up the product of estimated semivariograms ...

Relationship between exports, imports, and economic growth in France: evidence from cointegration analysis and Granger causality with using geostatistical models [PDF]

open access: yes
This paper introduces a new way of investigating linear and nonlinear Granger causality between exports, imports and economic growth in France over the period 1961-2006 with using geostatistical models (kiriging and inverse distance weighting ...

Production of a Porosity Map by Kriging in Sandstone Reservoirs, Case Study from the Sava Depression

open access: yesKartografija i Geoinformacije, 2008
Variogram analyses and usages of geostatistical interpolations have been standard analytical tools in Croatian geology in the last five years. Such analyses have especially been applied in the mapping of petroleum geological data.

Using Spatial Analysis to Study the Values of Variable Rate Technology and Information [PDF]

open access: yes
We present a review of the last few years' literature on the economic feasibility of variable rate technology in agriculture. Much of the research on this topic has involved the estimation of site-specific yield response functions.

Empirical semivariograms for kriging interpolation

open access: yes, 2009
Kriging interpolation is one of the more interesting techniques introduced in the field of surrogate modeling in the last years. This technique has been motivated by the necessity of data interpolation in the geological field in the late sixties. This approach is founded on the availability of the so called "variogram", defined as "a curve representing
