2. Ore resource estimation based on radial based functions - Case study on União Luiz and Morro do Carrapato Gold Deposits (Alta Floresta Gold Province)
Abstract Radial basis functions can be used as an alternative method for mineral resource estimation when ordinary kriging cannot be done because it is impossible to calculate an experimental variogram. Interpolation based on radial based functions is a method that is similar to ordinary kriging. In this context, this article presents the results of gold res

3. Two-scale topology optimization of macrostructure and porous microstructure composed of multiphase materials with distinct Poisson’s ratios
Abstract Negative Poisson’s ratio (NPR) material attracts a lot of attentions for its unique mechanical properties. However, achieving NPR is at the expense of reducing Young’s modulus. It has been observed that the composite stiffness can be enhanced when blending positive Poisson’s ratio (PPR) material into NPR material. Based on the respective inter

4. A TVD scheme for 3d unstructured grids applied to compositional reservoir simulation
Abstract In reducing the grid orientation effect for the numerical solution of partial differential equations, interpolation functions play an important role when the advective transport of the governing equations is considered. This is due to the fact that, in general, the unknowns are evaluated in the vertices of the elements and such properties must be ex

5. Finite Element Modelling for Static and Free Vibration Response of Functionally Graded Beam
Abstract A 1D Finite Element model for static response and free vibration analysis of functionally graded material (FGM) beam is presented in this work. The FE model is based on efficient zig-zag theory (ZIGT) with two noded beam element having four degrees of freedom at each node. Linear interpolation is used for the axial displacement and cubic hermite int

6. Comparison of an impec and a semi-implicit formulation for compositional reservoir simulation
In compositional reservoir simulation, a set of non-linear partial differential equations must be solved. In this work, two numerical formulations are compared. The first formulation is based on an implicit pressure and explicit composition (IMPEC) procedure, and the second formulation uses an implicit pressure and implicit saturation (IMPSAT). The main goal

7. Estudo baseado na interpolação 3D dos valores de RQD: barragem de Itaipu / Study based on 3D interpolation of the RQD values: Itaipu Dam (PR), Brazil
Este trabalho foi baseado na realização de simulações computacionais 3D de parâmetros de RQD obtidos de classificação geomecânica de sondagens rotativas realizadas nas fases de investigação geológico-geotécnica e construção da barragem de Itaipu (PR), Brasil. Tais simulações foram desenvolvidas em duas áreas dispostas no entorno da barragem

8. Aplicação do LIDAR no inventário de florestas plantadas / Lidar application in planted forest inventory
LIDAR (Light Detection and Ranging) has become an efficient tool for data extraction in forest inventory and other forest related studies. This works objective was to establish an efficient methodology for the use of this technology with the goal of counting the number of stems in a Eucalyptus plantation in South Bahia, Brazil, from the processing of raw dat

9. Cubic-spline interpolation to estimate effects of inbreeding on milk yield in first lactation Holstein cows
Milk yield records (305d, 2X, actual milk yield) of 123,639 registered first lactation Holstein cows were used to compare linear regression (y = β0 + β1X + e) ,quadratic regression, (y = β0 + β1X + β2X2 + e) cubic regression (y = β0 + β1X + β2X2 + β3X3 + e) and fixed factor models, with cubic-spline interpolation models, for estimating the effects o

10. Software for interpolation of vegetative growth of yerba mate plants in 3D.
Abstract ? The objective of this work was to build mock-ups of complete yerba mate plants in several stages of development, using the InterpolMate software, and to compute photosynthesis on the interpolated structure. The mock-ups of yerba-mate were first built in the VPlants software for three growth stages. Male and female plants grown in two contrasting e

12. REGISTRO DE SÍSMICA 3D A DADOS DE POÇOS / REGISTRATION OF 3D SEISMIC TO WELL DATA
Data acquired directly from borehole are more reliable than seismic data, and then, the first can be used to adjust the second. This work proposes the correction of a volume of seismic amplitudes through a three step algorithm. The first step is the identification of common features in both sets using a pattern recognition algorithm. The second step consists
