1. 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

2. Mensuração do erro de métodos de interpolação para modelos geoidais: Estudo de caso na região brasileira
Resumo: O geoide é a superfície equipotencial de referência altimétrica para levantamentos cartográficos e, portanto, apresenta diversas finalidades práticas para o engenheiro. Nas últimas décadas a comunidade geodésica tem concentrado esforços no desenvolvimento de modelos geoidais altamente acurados por meio de modernas técnicas. Esses modelos s

3. Hybrid Geoid Model: Theory and Application in Brazil
Determination of the ellipsoidal height by Global Navigation Satellite Systems (GNSS) is becoming better known and used for purposes of leveling with the aid of geoid models. However, the disadvantage of this method is the quality of the geoid models, which degrade heights and limit the application of the method. In order to provide better quality in transfo

4. Relative Performance of Three Mesh-Reduction Methods in Predicting Mode III Crack-Tip Singularity
Abstract Due to their robustness in handling the inherent singularity difficulties associated with crack analysis, mesh-reduction methods present an avalanche of formulations in the literature which, sometimes, entails modifications to their conventional/standard forms for better results. Although such formulations provide a pool of alternative choices to th

5. Nova abordagem para melhorar o desempenho do modelo de translação geocêntrica utilizando tecnologia de redes neurais artificiais
Resumo: O modelo de translação geocêntrica (GTM) atualmente não tem sido muito utilizado nas pesquisas de transformação de coordenadas devido a sua exatidão. Uma transformação acurada de coordenadas é um procedimento essencial na maioria dos problemas geodésicos. Entretanto, motivado pelo sucesso na aplicação de técnicas de Inteligência Artifi

6. Finite Element Analysis and Crashworthiness Optimization of Foam-filled Double Circular under Oblique Loading
Abstract Finite element analysis and optimization design carry out for the quasi static responses of foam-filled double circular tube is presented in this paper. In the investigation of the crashworthiness capability, some aspects were considered for variations in geometry parameters of tubes and the loading condition to investigate the crashworthiness capab

7. Study on Meshfree Hermite Radial Point Interpolation Method for Flexural Wave Propagation Modeling and Damage Quantification
Abstract This paper investigates the numerical modeling of the flexural wave propagation in Euler-Bernoulli beams using the Hermite-type radial point interpolation method (HRPIM) under the damage quantification approach. HRPIM employs radial basis functions (RBFs) and their derivatives for shape function construction as a meshfree technique. The performance

8. Buckling and Vibration of Functionally Graded Non-uniform Circular Plates Resting on Winkler Foundation
Abstract An investigation on the effect of uniform tensile in-plane force on the radially symmetric vibratory characteristics of functionally graded circular plates of linearly varying thickness along radial direction and resting on a Winkler foundation has been carried out on the basis of classical plate theory. The non-homogeneous mechanical properties of

9. Aplicação de redes Neuro Fuzzy ao processamento de peças automotivas por meio de injeção de polímeros
O processamento de peças automotivas por meio de injeção de polímeros envolve vários fenômenos físicos que ocorrem simultaneamente e que possuem caráter não linear e multivariável. Softwares comerciais podem ser utilizados na previsão dos parâmetros do processo, o que pode ser caro e inviável. Pode-se determinar os parâmetros de forma analític

10. Predicting the dynamic material constants of Mooney-Rivlin model in broad frequency range for elastomeric components
In this paper, dynamic material constants of 2-parameter Mooney-Rivlin model for elastomeric components are identified in broad frequency range. To consider more practical case, an elastomeric engine mount is used as the case study. Finite element model updating technique using Radial Basis Function neural networks is implemented to predict the dynamic mater

11. Prediction of monomer reactivity in radical copolymerizations from transition state quantum chemical descriptors
In comparison with the Q-e scheme, the Revised Patterns Scheme: the U, V Version (the U-V scheme) has greatly improved both its accessibility and its accuracy in interpreting and predicting the reactivity of a monomer in free-radical copolymerizations. Quantitative structure-activity relationship (QSAR) models were developed to predict the reactivity paramet

12. Design of multiple function antenna array using radial basis function neural network
A novel approach to design Multiple Function Antenna (MFA) arrays using Artificial Neural Networks is suggested. A planar array with uniform current excitations which can generate different beam widths and gains is designed using Artificial Neural Networks. The desired beam width, gain and number of elements are given as input to the neural network. The outp
