Plurigaussian modeling of geological domains based on the truncation of non-stationary Gaussian random fields
(Springer, 2017)
The plurigaussian model is used in miningengineering, oil reservoir characterization, hydrology andenvironmental sciences to simulate the layout of geologicaldomains in the subsurface, while reproducing their spatialcontinuity ...
Iterative algorithms for non-conditional and conditional simulation of Gaussian random vectors
(Springer, 2020)
The conditional simulation of Gaussian random vectors is widely used in geostatistical applications to quantify uncertainty in regionalized phenomena that have been observed at finitely many sampling locations. Two iterative ...
Inter-species variability of okadaic acid group toxicity in relation to the content of fatty acids detected in different marine vectors
(Taylor and Francis Ltd., 2019)
Okadaic acid group (OA-group) is a set of lipophilic toxins which are characterised by being produced by species associated with the genera Dinophysis and Prorocentrum. OA-group has been regularly detected in endemic ...
A comparison of search strategies to design the cokriging neighborhood for predicting coregionalized variables
(Springer New York LLC, 2019)
Cokriging allows predicting coregionalized variables from sampling information, by considering their spatial joint dependence structure. When secondary covariates are available exhaustively, solving the cokriging equations ...
An improved spectral turning-bands algorithm for simulating stationary vector Gaussian random fields
(2016)
We propose a spectral turning-bands approach for the simulation of second-order stationary vector Gaussian random fields. The approach improves existing spectral methods through coupling with importance sampling techniques. ...
Rapid screening fluorescence method applied to detection and quantitation of paralytic shellfish toxins in invertebrate marine vectors
(Taylor and Francis Ltd., 2019)
A rapid screening method is described for the determination of paralytic shellfish toxins (PST), in fresh marine vectors (bivalves and gastropods), at levels ranging from 0.05 to 5.0 mg STX-eq kg−1. PST are extracted from ...
