1. EXPLORAÇÃO DE OPERADORES ARITMÉTICOS NA TRANSFORMADA RÁPIDA DE FOURIER / ARITHMETICS OPERATORS EXPLORATION IN FAST FOURIER TRANSFORM
The power consumption reduction in the fast Fourier transform (FFT) is important because applications in battery-powered embedded systems grows daily. Thus this work focuses on the application of techniques to reduce power in specific projects of FFT algorithms. The goal is to achieve an architectural exploration in the FFT core, the decimation in time butte

2. Circuitos aritméticos e representação numérica por resíduos / Arithmetic circuits and residue number system
Este trabalho mostra os diversos sistemas de representação numérica, incluindo o sistema numérico normalmente utilizado em circuitos e alguns sistemas alternativos. Uma maior ênfase é dada ao sistema numérico por resíduos. Este último apresenta características muito interessantes para o desenvolvimento de circuitos aritméticos nos dias atuais, com

3. Modelagem de sistemas dinamicos não lineares utilizando sistemas fuzzy, algoritmos geneticos e funções de base ortonormal / Modeling of nonlinear dynamics systems using fuzzy systems, genetic algorithms and orthonormal basis functions
This work introduces a methodology for the generation and optimization of Takagi-Sugeno (TS) fuzzy models with Orthonormal Basis Functions (OBF) for nonlinear dynamic systems based on a genetic algorithm. Orthonormal basis functions have been used because they provide models with properties like absence of output feedback and the possibility to reach a reaso

4. Traces, ideals, and arithmetic means
This article grew out of recent work of Dykema, Figiel, Weiss, and Wodzicki (Commutator structure of operator ideals) which inter alia characterizes commutator ideals in terms of arithmetic means. In this paper we study ideals that are arithmetically mean (am) stable, am-closed, am-open, soft-edged and soft-complemented. We show that many of the ideals in th
