Born in Brazil in 1969, Paulo Ricardo Lourenço Alves' early research was in Time Series Analysis in the reconstruction scheme. His work improves the method of forecasting in this area with his programs in the Algebraic Computation environment. He soon focused on a new characterization of chaos from a time series. The paper published in 2017 distinguishes chaos and randomness in systems of the real world. Nowadays, he intends to apply this method to the branch of Econophysics. The transposition of his routines for data fitting problems is also in your scope of activity. Another field of research is the detecting of stress in materials with ultrasound.
