Universal Kriging Prediction of nonstationary Spatial Stochastic Process [PDF]

open access: yesالمجلة 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 ...

Calibration and improved prediction of computer models by universal Kriging [PDF]

open access: yesNuclear Science and Engineering, 2013
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 ...

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.

Universal Kriging for Accurate Shadow Fading Modeling in LOS/NLOS Conditions

open access: yesIEEE Open Journal of Antennas and Propagation
Traditional path loss (PL) models often fail to capture the spatial characteristics of wireless channels in environments combining line-of-sight (LOS) and non-line-of-sight (NLOS) conditions, where shadow fading exhibits clear spatial non-stationarity ...

Comprehensive Measurement-Based Assessment of Downlink RF-EMF Exposure in Urban Environments: Multi-Method Analysis and Intercomparison. [PDF]

open access: yesBioelectromagnetics
ABSTRACT This paper presents a comprehensive measurement‐based assessment of radio‐frequency (RF) electromagnetic field (EMF) exposure level in a French city. Three types of assessment methods are used to collect measurement data: drive test (DT), spot measurements, and sensor networks. The DT measurements were conducted by a portable spectrum analyzer,

A geostatistical analysis of multiscale metallicity variations in galaxies [II]: Predicting the metallicities of H ii and diffuse ionised gas regions via universal kriging [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2022
The metallicity of diffuse ionised gas (DIG) cannot be determined using strong emission line diagnostics, which are calibrated to calculate the metallicity of H ii regions.

An Optimized Fingerprinting-Based Indoor Positioning with Kalman Filter and Universal Kriging for 5G Internet of Things

open access: yesWireless Communications and Mobile Computing, 2021
Fingerprinting technique for indoor positioning based on 5G system has attracted attention. Kalman filter (KF) is used as preprocessing of raw data to reduce the disturbance of Received Signal Strength (RSS) values. After preprocessing, Universal Kriging
