The effective sample size for multivariate spatial processes with an application to soil contamination
(2021)
Effective sample size accounts for the equivalent number of independent observations contained in a sample of correlated data. This notion has been widely studied in the context of univariate spatial variables. In that ...

Sample arrangements and spatial variability characterization of dendometrics parameters of Eucalyptus camaldulensis and physical soil attributes
(2021-01-01)
To evaluate the performance of different sampling arrangements, this work aimed to study, in a field of Eucalyptus camaldulensis, the variability and spatial dependence of some attributes of plant and soil (LATOSSOLO ...
Does spatial visualization ability improve after studying technical drawing?
(Springer, 2010-08-01)
Two studies were carried out to analyze whether learning technical drawing improves a person's ability for spatial visualization. Visualization and inductive reasoning tests were applied at the beginning and end of a course ...

The sugarcane borer Diatraea saccharalis (Fabr.) (Lep., Crambidae) and its parasitoids: a synchrony approach to spatial and temporal dynamics
(Blackwell Verlag Gmbh, 2003-05-01)
A data set on Diatraea saccharalis and its parasitoids, Cotesia flavipes and tachinid flies, was analysed at five spatial scales-sugarcane mill, region, intermediary, farm and zone-to determine the role of spatial scale ...
