2011), albeit not in fruit culture, were used in current study to identify the spatial variability structure of the variables by means of geostatistics and ordinary kriging interpolation.
Precipitation estimation in mountainous terrain using multivariate geostatistics.
In this context, geostatistics and simulation models are used to predict variables and create scenarios, allowing to generate zonings, thus indicating the best sowing periods with lower risks to the crop.
Geostatistics can be used to represent the spatial distributions of environmental factors and examine the ecological aspects of recovery and these tools have been used by numerous researchers to examine the spatial dependence of forest components (Rufino, Thiersch, Ferreira, Kanegae-Junior, & Fais, 2006; Amaral, Ferreira, Watzlawick, & Genu, 2010; Neves, Lemos, Gonzales, Vieira, & Siqueira, 2010; Amaral, Ferreira, Lisboa, Longhi, & Watzlawick, 2013a).
A member of the US National Academy of Engineering, he is globally recognised for his research and publications in fundamental processes, integrated reservoir characterization, geostatistics, reservoir engineering and enhanced oil recovery.
Geostatistics using modeling allows the quantitative description of the spatial variability of soil attributes and the non-biased estimation and with minimum variance of values of the attributes in non-sampled areas (Silva et al.
Integration of mid-infrared spectroscopy and geostatistics in the assessment of soil spatial variability at landscape level.
The topics include the nonlinear vibration control of three-dimensional irregular structures subjected to seismic loads, analyzing spatial variability in soil using geostatistics, adaptive fuzzy modeling using orthonormal basis functions to control the flow of network traffic, molecular dynamic simulations of the oxidative aging of asphalt molecules under stress and moisture, and applying cluster analysis in computational paleography.
Therefore, geostatistics is an important tool for estimating dendrometric characteristics as an efficient and low-cost method for guiding management techniques in planted forest areas.
The aims of this paper are to: (i) summarise, characterise and interpret sources of uncertainty in the assessment of soil change; (ii) describe applications of uncertainty analysis in soil-change research; (iii) represent uncertainty analysis in soil change in the form of a systems-based process model that captures the major sources of uncertainty in the modelling process; and (iv) provide illustrative examples in the context of error disaggregation and geostatistics.
