Spatio-Temporal Analysis of Drought Severity Using Drought Indices and Deterministic and Geostatistical Methods (Case Study: Zayandehroud River Basin) [PDF]

open access: yesDesert, 2016
Drought monitoring is a fundamental component of drought risk management. It is normally performed using various drought indices that are effectively continuous functions of rainfall and other hydrometeorological variables.

Enhanced universal kriging for transformed input parameter spaces

open access: yesProbabilistic Engineering Mechanics, 2023
With computational models becoming more expensive and complex, surrogate models have gained increasing attention in many scientific disciplines and are often necessary to conduct sensitivity studies, parameter optimization etc. In the scientific discipline of uncertainty quantification (UQ), model input quantities are often described by probability ...

Augmenting Geostatistics with Matrix Factorization: A Case Study for House Price Estimation

open access: yesISPRS International Journal of Geo-Information, 2020
Singular value decomposition (SVD) is ubiquitously used in recommendation systems to estimate and predict values based on latent features obtained through matrix factorization.

Regional scale surface of the top of the Variscan basement in the central sector of Italy

open access: yesJournal of Maps, 2023
In this study, we combined regional geology and geostatistical analytical processing to model the top surface of the Variscan basement in Italy. This surface, which is overlain by the pre-Alpine sedimentary cycle (Upper Carboniferous – Permian) followed ...

COMPARISON OF ORDINARY AND UNIVERSAL KRIGING INTERPOLATION TECHNIQUES ON A DEPTH VARIABLE (A CASE OF LINEAR SPATIAL TREND), CASE STUDY OF THE ŠANDROVAC FIELD

open access: yesRudarsko-geološko-naftni Zbornik, 2016
Universal Kriging has not until now been used for mapping of geological data in Croatia. However, it is one of the most frequently used methods of Kriging, probably the most adequate in cases when the input data is marked by a common trend.

Comparation to the Methods of Interpolation with ASTER GDEM V2 Based on ICESat/GLA14 Lvliang Mountains in Shanxi Province

open access: yesChemical Engineering Transactions, 2015
ICESat/GLA14, a series of altitude points with high accuracy, it can be used for ASTER GDEM data’s accuracy correction, while the rational interpolation method is the important guarantee for the quality of ASTER GDEM data correction results.

Calibration and Improved Prediction of Computer Models by Universal Kriging [PDF]

open access: yesNuclear Science and Engineering, 2014
This paper addresses the use of experimental data for calibrating a computer model and improving its predictions of the underlying physical system. A global statistical approach is proposed in which the bias between the computer model and the physical system is modeled as a realization of a Gaussian process.
