    • Comparative study between EDXRF and ASTM E572 methods using two-way ANOVA 

      Krummenauer, Alex; Veit, Hugo Marcelo; Ferreira, Jane Zoppas (2018) [Journal article]
      Comparison with reference method is one of the necessary requirements for the validation of non-standard methods. This comparison was made using the experiment planning technique with two-way ANOVA. In ANOVA, the results ...
    • Computational image analysis as an alternative tool for the evaluation of corrosion in salt spray test 

      Moreira, Vitor Bonamigo; Krummenauer, Alex; Ferreira, Jane Zoppas; Veit, Hugo Marcelo; Armelin, Elaine; Meneguzzi, Alvaro (2020) [Journal article]
      The current standards for evaluating corrosion during salt spray tests rely on the visual analysis of the specimens, and this may be a limitation when higher resolution quantitative outputs are desired. In this work, ...
    • Evaluation of mass loss in different stages of printed circuit boards recycling employed in temperature controllers 

      Schneider, Eduardo Luís; Hamerski, Fernando; Veit, Hugo Marcelo; Krummenauer, Alex; Cenci, Marcelo Pilotto; Chaves, Rodrigo de Andrade; Hartmann, Wagner Luiz; Dias, Moisés de Mattos; Robinson, Luiz Carlos; Vargas, Alexandre Silva de (2019) [Journal article]
      The aim of this work was to evaluate mass loss in each stage of the recycling process for metal recovery from PCBs of controllers and temperature indicators of cold chambers. The stages of process consists of grinding, ...
