Hi, my name is Guilherme Oliveira de Brito. I add some knowledge in mathematics and engineering that is widespread in my region (south of Brazil) which I can't find on the English Wikipedia. I suppose most of them are part of folk mathematics/folk engineering, since they are absent in the English version. By the way, I am a fan of bond graphs and I am currently working towards expanding its Wikpedia's article.
