1. Geração de b-splines via FPGA / B-spline generation via FPGA
The b-splines are used in CAD/CAM/CAE systems to represent and define complex curves and surfaces, being adopted by the main computer graphics standards due to features like compact mathematic representation, flexibility and affine transformations. In 3D acquisition systems and integrated CAM-CNC systems, the use of the b-spline in the geometric information

11. Sistema interativo de modelagem e simulação de sistemas flexiveis de manufatura-sisma
Inside the current complexity of the highly automated, computer-controlled manufacturing systems, even the most careful analytical planning sometimes fails to prevent major blunders. This fact has caused organizations to increasingly turn to simulation for dynamic analysis of these systems prior to any implementation. However, simulation modelling studies te
