Aplicação da Geoestatística Não-paramétrica para a compartimentação geomecânica de uma extensão típica do túnel do metrô - Linha 4, da cidade de São Paulo
(2006-01-01)
In view of the limited number of drill holes, interpolation of the data becomes a relatively complex task. In this study, we sought to make estimates associated with lithological types, since a quantification based on ...
Geostatistical analysis of the spatial distribution of Rotylenchulus reniformis on cotton cultivated under crop rotation
(Mylnefield Research Services, 2002-01-01)
The spatial distribution of Rotylenchulus reniformis on cotton cultivated in crop rotation with sorghum-peanut-velvetbean was studied using geostatistics. The experimental field, which had been continuously cropped with ...
Comparison between univariate and bivariate geostatistical models for estimating catch per unit of effort (cpue): A simulation study
(Elsevier B.V., 2012-06-01)
Data on catch and fishing effort are used for estimating the relative abundance of a fish stock. Geostatistical models have been used in this sort of analysis. Multivariate geostatistical models have been used in several ...
Delimitação do Embasamento da Bacia de Taubat
(2011-04-01)
The aim of this study is to define the basement map of the Taubaté Basin applying geostatistics to seismic, gravimetric and deep wells data. The study consisted of the interpretation of eleven seismic sections obtained in ...
Stochastic simulation of time-series models combined with geostatistics to predict water-table scenarios in a Guarani Aquifer System outcrop area, Brazil
(Springer, 2012-11-01)
Stochastic methods based on time-series modeling combined with geostatistics can be useful tools to describe the variability of water-table levels in time and space and to account for uncertainty. Monitoring water-level ...
Using geostatistical analysis to evaluate the presence of Rotylenchulus reniformis in cotton crops in Brazil: Economic implications
(Soc Nematologists, 2002-09-01)
In recent years, the productivity of cotton in Brazil has been progressively decreasing, often the result of the reniform nematode Rotylenchulus reniformis. This species call reduce crop productivity by up to 40%. Nematodes ...
A classification for a geostatistical index of spatial dependence
(Sociedade Brasileira de Ciência do Solo (SBCS), 2019)
Comparing three indices of catch per unit effort using Bayesian geostatistics
(Elsevier B.V., 2009-11-01)
In assessing a fish stock, indices based on catch per unit effort (CPUE) are frequently used. Estimates of three indices of catch per unit effort were compared here (CPUE(1), CPUE(2) and CPUE(3)), considering the fitting ...
Variabilidade espacial de atributos químicos em um Argissolo sob pastagem
(Universidade Estadual de Maringá (UEM), Pro-reitoria Pesquisa Pos-graduacao, 2008-10-01)
Studies show the importance of knowing the variability of soil attributes for a more efficient management. This work was carried out to evaluate the spatial variability of the chemical attributes of an Ultisol, cultivated ...
