Spatial interpolation of water quality index based on Ordinary kriging and Universal kriging
Geomatics, Natural Hazards & Risk, 2023 Water is a very vital needed substance in order to maintain the important activities of humans. However, contaminated water can transmit diseases such as typhoid, dysentery, diarrhea, cholera and polio.

Using Universal Kriging to Improve Neighborhood Physical Disorder Measurement [PDF]
Sociological Methods and Research, 2020 Ordinary kriging, a spatial interpolation technique, is commonly used in social sciences to estimate neighborhood attributes such as physical disorder. Universal kriging, developed and used in physical sciences, extends ordinary kriging by supplementing the spatial model with additional covariates.

Universal Kriging Prediction of Line-of-Sight Microwave Fading [PDF]
IEEE Access, 2020 Prediction of the severity of multipath fading is fundamental to the design of point-to-point terrestrial fixed microwave links at frequencies below 10 GHz, but error in this prediction may be significant in countries such as Australia, not represented ...

Universal kriging for spatio‐temporal data
Mathematical Modelling and Analysis, 2003 In this article we have used wide applicable classes of spatio‐temporal nonseparable and separable covariance models. One of the objectives of this paper is to furnish a possibility how to avoid the usage of complicated covariance functions.

The improvement of strain estimation using universal kriging [PDF]
Acta Geodaetica Et Geophysica, 2015 In this paper, universal kriging with linear trend is used to interpolate the strain tensor elements over a region along San Andreas Fault in California. The main goal of this paper is to improve the ordinary kriging interpolation results. A 7-year time series (2006–2012) of 12 permanent stations is utilized to obtain the coordinate changes in UTM ...

Universal Kriging Prediction of nonstationary Spatial Stochastic Process [PDF]
المجلة العراقية للعلوم الاحصائية, 2010 Spatial Stochastic processes are often divided into two types that are stationary spatial stochastic processes and other nonstationary. In most practical applications the processes are nonstationary .Prediction of these processes are performed by ...

Spatial analyses of groundwater levels using universal kriging
Journal of Earth System Science, 2007 For water levels, generally a non-stationary variable, the technique of universal kriging is applied in preference to ordinary kriging as the interpolation method. Each set of data in every sector can fit different empirical semivariogram models since they have different spatial structures.

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