Controle y Automacao, v. 16, v. 1, p. 34-43, January/March, 2005.0103-1759https://repositorio.fei.edu.br/handle/FEI/4371This work presents the methodology from the determination the charge's superficial density, in two simple structure a to straight thread and in plane plates, both finite and submitted to a constant potential. That involves the method of the moments using as expansion function the wavelets instead of the pulse function, in order to reach a good precision and reducing the computational execution time. We also intends to take advantages of the wavelets application through the Cholesky decomposition, talking about formation of scattered matrixes, and the detection of nulls values.Acesso AbertoArtigo de revisão10.1590/s0103-17592005000100004Wavelets
