This work reports the observation of quasiperiodic behavior during the oscillatory electrodeposition of Cu/Sn multilayers. By employing a wavelet transform on the current from the time-series, and by varying the temperature, it was possible to extract two apparent activation energies from the oscillation frequencies, of two different domains: one believed to be mainly activation limited (near 50 kJ/mol), extracted from a higher frequency oscillation, and one thought to be mainly diffusion limited (near 20 kJ/mol), extracted from a lower frequency oscillation. These energies are comparable to those calculated using current values from the cyclic voltametry in different temperatures.

The aim of this paper is to describe the importance of quantitative research methods using databases, also describes the steps taken for the development of a free tool -BRAVO. The tool offers, in a simplified way, the generation of dynamic filters and reports for educational researchers, using as the source of knowledge extraction the databases and microdata provided by Instituto Nacional de Estudos e Pesquisas em Educacionais Anísio Teixeira (INEP), timeline 2007-2014. Resumo. O objetivo deste trabalho é expor a importância dos métodos de pesquisa quantitativos utilizando-se bancos de dados assim como apresentar o desenvolvimento de uma ferramenta livre de apoio à pesquisa em educação -BRAVO. A ferramenta oferece, de forma simplificada, a geração de filtros dinâmicos e relatórios gerenciais para pesquisadores da área da educação e afins, utilizando-

This study employ a multivariate statistical analysis in chemical and electrochemical oscillators to determine accurately the effect of experimental parameters on the oscillation frequency. This work has been published in Physical Chemistry Chemical Physics (PCCP) and highlighted as an outside front cover.
