DETERMINAÇÃO SIMULTÂNEA DE METAIS EM GASOLINA, ATRAVÉS DE MÉTODO ELETROANALÍTICO ALTERNATIVO, COM O USO DE CALIBRAÇÃO MULTIVARIADA / REDES NEURAIS
Autor: Edmar P. Marques, Joseany M. S. Almeida, Delano Brandes Marques, Elmo de Sena Ferreira Júnior, Aldaléa L. B. Marques
Publikováno v: Cadernos de Pesquisa.
Devido a complexidade de amostras como a gasolina, a utilização de microemulsões, bem como de estratégias de calibração multivariada tem sido cada vez maior. Este trabalho apresenta o uso do programa STATISTICA 10.0 na aplicação de redes neur
