1. Simulação numérica da intermitência alfvência na heliosfera na presença de ruído / Numerical simulation of alfvénic intermittency in heliosphere in the presence of noise
The study of intermittency and chaos is necessary for our understanding of the complex physical processes governing the Sun-Earth relation, where the presence of multiple steady states can lead to complex dynamics if there is a stocastic source. The objective of this work is to apply the chaos theory to investigate the intermittent nature of the heliospheric

2. Sthocastic model for estimating potential maize productivity in Piracicaba-SP, Brazil. / Modelo estocástico para estimação de produtividade potencial de milho em Piracicaba - SP.
With the purpose of proposing a stochastic model for estimating potential maize productivity in Piracicaba (SP), as function of mean values of daily air temperature and solar radiation, a software was developed using Visual Basic for Windows, where it was applied for different agro climatic periods (sowing dates). The results allowed the following conclusion

3. Estrategias de otimização de processos
In the present work a strategy of set optimization is proposed by joining deterministic and statistics techniques. Intents to do analyses of integration of the energy point of view and mass. This strategy seeks the use of the mathematical formalism, used in the simulation and optimization units for half deterministic, as well as the employment of stocastic m

4. Integração de dados para caracterização preliminar de reservatorio de hidrocarboneto
A series of univariate and multivariate geostatistical techniques were tested and applied to a set of seismic and well-log data obtained from an oil field offshore Brazil. The goal was to estimate petrophysical parameters of the reservoir using integrated seismic and well-log data, with the use of empirical relations between seismic data and petrophysical pa
