1. Real-time photographic local tone reproduction using summed-area tables / Reprodução fotográfica local de tons em tempo real usando tabelas de áreas acumuladas
A síntese de imagens com alta faixa dinâmica é uma prática cada vez mais comum em computação gráfica. O desafio consiste em relacionar o grande conjunto de intensidades da imagem sintetizada com um sub-conjunto muito inferior suportado por um dispositivo de exibição, evitando a perda de detalhes contrastivos. Os operadores locais de reprodução de

2. Uso de imagens Radarsat-1 para fins de mapeamento de uso da terra e cobertura do solo em ambiente tropical úmido urbano: o caso de Manaus, Estado do Amazonas. / Use of radarsat-1 data in the identification of targets related to land use and land cover in urban humid tropical region: the case of Manaus, state of the Amazon, Brazil
The use of remote sensing data acquired through Synthetic Aperture Radar has been a recent common trend for land use and land cover mapping purposes. The information derived from this kind of data has been applied to distinct related application fields, such as: urban pattern analysis and mapping, settlements identification, urban change detection and even m

3. The Use of Computer Mapping in Health Research
Display of quantitative data characterizing geographic regions is often most graphically accomplished by the use of outline maps, with enclosed regions shaded or toned to represent data associated with them. Such maps are of considerable value to hospital or regional health planners in demonstrating geographic and demographic characteristics of their service

4. Measurement of abdominal wall compliance in normal subjects and tetraplegic patients.
On inspiration descent of the diaphragm is opposed by the passive properties of the abdominal wall, the tone of its muscles, and the inertia of the abdominal contents. As a result, intra-abdominal pressure rises and promotes rib cage expansion. In patients with high spinal injury the diaphragm is the most important muscle of inspiration and abdominal wall di

5. Parsing a Cognitive Task: A Characterization of the Mind's Bottleneck
Parsing a mental operation into components, characterizing the parallel or serial nature of this flow, and understanding what each process ultimately contributes to response time are fundamental questions in cognitive neuroscience. Here we show how a simple theoretical model leads to an extended set of predictions concerning the distribution of response time

6. The Dissonance Mutant of Courtship Song in Drosophila Melanogaster: Isolation, Behavior and Cytogenetics
The dissonance mutant of courtship song was induced by chemical mutagenesis. This X-chromosomal mutation causes the D. melanogaster male's acoustical output, resulting from his wing vibrations directed at a female, to include very long and loud tone ``pulses.'' Yet, a given train of pulses starts out as normal, with the signals in all but the shortest singin
