Assessment of Severity of Droughts Using Geostatistics Method(Case Study: Southern Iran) [PDF]

open access: yesDesert, 2013
Drought monitoring is a fundamental component of drought risk management. It is normally performed usingvarious drought indices that are effectively continuous functions of rainfall and other hydrometeorological variables.In many instances, drought ...

Ordinary kriging as a tool to estimate historical daily streamflow records [PDF]

open access: yesHydrology and Earth System Sciences, 2016
Efficient and responsible management of water resources relies on accurate streamflow records. However, many watersheds are ungaged, limiting the ability to assess and understand local hydrology.

Mapping the topsoil pH and humus quality of forest soils in the North Bohemian Jizerské hory Mts. region with ordinary, universal, and regression kriging: cross-validation comparison

open access: yesSoil and Water Research, 2013
North Bohemia belongs to one of the most heavily industrialized and polluted regions in Europe. The enormous acid deposition which culminated in the 1970s has largely contributed to the accelerated acidification process in the soils and consequently to ...

Monitoring of power factor for induction machines using estimation techniques [PDF]

open access: yes, 2015
Power factor is a significant element in power systems which is defined as the angle difference between voltages and currents that produces power fluctuation between sources and loads.

On Prediction Properties of Kriging: Uniform Error Bounds and Robustness

open access: yes, 2019
Kriging based on Gaussian random fields is widely used in reconstructing unknown functions. The kriging method has pointwise predictive distributions which are computationally simple. However, in many applications one would like to predict for a range of

Kriging Interpolating Cosmic Velocity Field

open access: yes, 2015
[abridged] Volume-weighted statistics of large scale peculiar velocity is preferred by peculiar velocity cosmology, since it is free of uncertainties of galaxy density bias entangled in mass-weighted statistics.

Simplicial Indicator Kriging

open access: yesJournal of China University of Geosciences, 2008
Indicator kriging (IK) is a spatial interpolation technique devised for estimating a conditional cumulative distribution function at an unsampled location. The result is a discrete approximation, and its corresponding estimated probability density function can be viewed as a composition in the simplex. This fact suggested a compositional approach to IK
