7. Identificação de evasão fiscal utilizando dados abertos e inteligência artificial
Resumo A evasão fiscal é a consequência da prática da sonegação. Apenas no Brasil, estima-se que ela corresponda a 8% do PIB. Com isso, os governos necessitam de sistemas inteligentes para apoiar os auditores fiscais na identificação de sonegadores. Tais sistemas dependem de dados sensíveis dos contribuintes para o reconhecimento dos padrões, que s

The existence of words as context-free entities is not just a “cognitive idealization” however but a necessity, as otherwise speakers would have to make up their wo

12. Possible Effects of Oriented Magnetic Fields on Human Blood Pressure
Abstract Background: There have been scattered reports indicating the possibility that applied magnetic fields can lower human blood viscosity, which has been considered as encouraging for decreasing blood pressure as a result of greater fluidity. Additional motivation comes from partial studies in animals showing some response of vascular variables to magn
