8. Accuracy of intraoral and extraoral digital data acquisition for dental restorations
ABSTRACT The computer-aided design (CAD) and computer-aided manufacturing (CAM) process chain for dental restorations starts with taking an impression of the clinical situation. For this purpose, either extraoral digitization of gypsum models or intraoral digitization can be used. Despite the increasing use of dental digitizing systems, there are only few st

11. 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

12. Uma Linguagem de ProgramaÃÃo Paralela Orientada a Objetos para Arquiteturas DistribuÃdas / A Programming Language for Parallel Object-Oriented Distributed Architectures
Em programaÃÃo orientadas a objetos (POO) , a habilidade de encapsular interesses de software da dominante decomposiÃÃo em objetos à a chave para alcanÃar alto nÃvel de modularidade e diminuiÃÃo de complexidade em projetos de larga escala. Entretanto, o paralelismo de memÃria distribuÃda tende a quebrar modularidade, encapsulamento e a independÃn
