1. ANALYSIS OF THE BASELINE DRIFT ARTIFACT IN HADAMARD TRANSFORM SEPARATION TECHNIQUES
The baseline drift artifact (BDA), namely, the baseline bias between the Hadamard transform (HT) spectrum and the signal averaging (SA) spectrum was unfortunately found in the HT pulsed separation techniques, which makes the HT analytical chemistry face the challenge of non-stability and unreliability. In order to find out the origin and eliminate the BDA ph

2. Sistema de codificação de video baseado em transformadas tridimensionais, rapidas e progressivas / Video coding system based on three dimensional, fast and progressive transforms
The research on video coding systems has always been looking for techniques that can reach the highest possible compression rate. This compression rate increase is generally achieved by means of increased coding complexity, which is supported by the continuous increase verified in computational power. However, in some video coding and transmission situations

3. Construção de um expectrofotometro com transformada de Hadamard e sua aplicação na analise por injeção em fluxo
A fast scanning Hadamard spectrophotometer which is capable to obtain a complete spectra in the visible region in time intervals down to 50 ms has been developed. The spectrophotometer control and data acquisition were performed by a single board microcomputer based on a CPU 8085. This single board sends data, in serial mode, to an IBM PC compatible microcom
