13. Estudo eletromiografico da influencia dos musculos biceps e triceps do braço e braquiorradial, nas diferentes posições articulares do ombro
The purpose of this study was to analyze the influence of biceps raquialis, braquiorradial, and triceps braquialis on the flexon activity at different positions of the shoulder joint. It was observed the isometric semipronate elbow flexion contractions with anatomical position of the shoulder, 90° shoulder flexion and 90s houder abduction. Ten healthy femal

14. Atividade eletrica dos musculos esternocleidomastoideo e trapezio - fibras superiores em individuos normais e disfonicos
The purpose of the present study was to evaluate bilateral electric activity of muscles sternocleidomastoid (SCM) and superior fibers of trapezius (SFT) in clinicalIy normal and dysphonic subjects during rest and phonation. The electric activity was measured in 20 female subjects, divided into two groups: the Control Group consisting of 10 subjects aged betw

15. Projeto de um conversor analogico/digital ultra-rapido bipolar tipo folding com uma nova tecnica de interpolação
In an analog/digital converter with folding architecture and interpolation, the most significant bits are determined by a quantization of the input signal using a folding circuit, while the least significant bits are obtained by interpolation technique. The interpolation reduces the complexity of the circuits without increasing the folding rate of the system

16. Blocos CMOS de alta performance para aplicações em VLSI
This work compiles the design of three high performance CMOSdigital circuits blocks where the best area/speed relationship was required. Those circuits are intended to be implemented in VISI circuits. One of the blocks, the 8 bits A/D Converter, was implemented using a modified flash architecture, which allows conversion ratio above 1 MHz, suitable to the mo

17. Nova tecnica de conversão analogica digital não-linear
A new technique for obtaining nonlinear A/D conversion with convencional dual slope converter is presented. The work includes the generalization of the conversion method, a particular study for linearization of polinomyal functions, and the realization of a pratical converter. The results showed that the new converter can be largely used in measument equipme
