Spatial Prediction and Optimized Sampling Design for Sodium Concentration in Groundwater. [PDF]

open access: yesPLoS ONE, 2016
Sodium is an integral part of water, and its excessive amount in drinking water causes high blood pressure and hypertension. In the present paper, spatial distribution of sodium concentration in drinking water is modeled and optimized sampling designs ...

Kriging Model for Time-Dependent Reliability: Accuracy Measure and Efficient Time-Dependent Reliability Analysis Method

open access: yesIEEE Access, 2020
As the performance function of a mechanical structure is usually based on time-consuming computer codes, predicting time-dependent reliability analysis requires a large number of costly simulations in engineering.

Efficient simulation-driven design optimization of antennas using co-kriging [PDF]

open access: yes, 2012
We present an efficient technique for design optimization of antenna structures. Our approach exploits coarse-discretization electromagnetic (EM) simulations of the antenna of interest that are used to create its fast initial model (a surrogate) through ...

Detailed mapping of soil texture of a paddy growing soil using multivariate geostatistical approaches

open access: yesTropical Agricultural Research, 2018
This study was conducted to explore performances of multivariate geostatistical techniques, co-kriging and regression kriging in contrast to univariate ordinary kriging, to generate detailed maps of soil texture by using proximally sensed apparent ...

Metamodel-Assisted Multidisciplinary Design Optimization of a Radial Compressor

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2019
Kriging is increasingly used in metamodel-assisted design optimization. For expensive simulations; however, one can afford only a few samples to build the Kriging model, which consequently lacks prediction accuracy.

Comparison of sensitivity of interpolation methods by rain gauge network density [PDF]

open access: yesعلوم و مهندسی آبیاری
Different interpolation methods, each with their own strengths and weaknesses, are used to temporal and spatial estimation of precipitation. The accuracy of this estimate depends on the density of point data measured at rain gauge stations. In this study,

Review of Dace-Kriging Metamodel [PDF]

open access: yesInterdisciplinary Description of Complex Systems, 2023
This paper presents a conceptual review of the kriging metamodel that is introduced for the design and analysis of computer experiments (DACE). Kriging is a statistical interpolation method to build an approximation model from a set of evaluations of the
