1. Acionamento vetorial de motores de indução trifásicos com enfraque-cimento de campo e maximização do conjugado por ampère
This work investigates the operation of three phase induction motors in field weakening and high speed regions. Maximum torque per ampère is imposed by using an indirect vector control strategy. Mathematical models that accounts for magnetic saturation is used for simulations and adjustment of controllers used in control algorithm. The driving structure is

2. Suporte a simulação distribuída em SystemC
The ever increasing evolution of microelectronics allows the integration of more and more complex systems in semiconductor devices. Present day System on Chip (SoC) may integrate processors, memories, analog, mixed-signals, digital and RF modules in a single chip. The simulation of a SoC is a fundamental step in system design, since it permits the verificati

3. MultiplexaÃÃo por DivisÃo em MultirresoluÃÃo: um novo sistema baseado em wavelets / Multiresolution division multiplex: A new wavelet - based system
A new multiplex scheme is introduced, which is based on Mallatâs multiresolution formulation of wavelet systems. After the presentation of the basic tools for the development of this work, the system is introduced and a number of schemes is shown, with different configurations, so as to illustrate the potential and versatility of this new multiplex approach

4. Performance Analisys of Multicarrier Systems in Peak Clipping Channels / Análise de Desempenho de Sistemas Multiportadora em Canais com Ceifamento de Pico
The advent of Digital Television brought a new scenario to the digital telecommunication systems, presenting new problems and challenges to be efficiently solved. Today, there are three different standards for Digital Television available: the ATSC developed in USA, DVB-T developed in Europe and ISDB-T developed in Japan. Two of these standards use a transmi
