13. Implementação de uma metodologia para mineração de dados aplicada ao estudo de núcleos convectivos / Implementation of methodology for data mining applied to the study of convective nucleous
In this work, a methodology for data mining was implemented using the rough sets theory and applied to the study of convective nucleous. Data mining has been used to analyze large volumes of data trying to identify frequent correlations, patterns, and outliers, in the most varied domains of applications, including scientific research. In this study, data min

14. ESTUDO PARA O DESENVOLVIMENTO DE UM PREVISOR DE DESCARGAS ELÉTRICAS ATMOSFÉRICAS APLICADO À REGIÃO COSTEIRA DO ESTADO DO RIO DE JANEIRO
The atmospheric dynamics evidently is very complex. There are many macro and micron scales processes and meteorological variables involved in the atmospheric physicalphenomena. The storms with electrical discharges are distinguished, among these phenomena, by the damage consequences to the human beings, directly or indirectly. Many researchers have pursued t

15. Effect of air-oxygen and argon-oxygen mixtures on dielectric barrier discharge decomposition of toluene
One alternative application in the decomposition and destruction of volatile organic compounds (VOCs) by a silent plasma dielectric barrier discharge (DBD) has been successfully accomplished. For this purpose, we have designed and constructed two pairs of cells, of rectangular and circular geometries, 333.96 cm³ each cell, and a similar second pair of 62.25

16. Projeto otimizado de uma unidade de air stripping para remover VOCs clorados de aguas residuarias
At present, it is more and more common to find water resources contaminated by substances resulting from anthropogenic activities, especially those originating from of the discards of industrial processes. These chemicals usually represent a threat to human health and to aquatic ecosystems equilibrium. The effects are still more harmful when such substances

17. Estudo da forma de onda de campo elétrico de relâmpagos / Study of the electric field waveform of lightning.
Neste trabalho são analisadas formas de onda de campo elétrico da radiação eletromagnética gerada por relâmpagos ocorridos na cidade de São José dos Campos e vizinhança. Para a aquisição das formas de onda de campo elétrico foi utilizado um aparato composto por uma antena ligada a uma eletrnica, a qual processa o sinal proveniente da antena e o
