13. Functional vision barriers: a new concept analyzed in terms of human visual performance
In this work we introduce a new category of barriers that we call "functional vision barriers." This expression refers to lighting and visual elements that may complicate or hinder functional vision and may make life even more difficult for people with visual defects. These barriers appear as a consequence of certain negative effects caused by the poor desig

14. Rastreamento em vídeo das características da pupila / Video tracking of pupil features
The study of the pupil s movements has signicant clinical interest because it acts as an objective indicator of retinal sensitivity to light and, consequently, of the optic nerve. Its permanent oscillation is the result of balance between opposing ows of the sympathetic and parasympathetic nervous system. The pupil s state of an individual allows the diagnos

15. Sistemas de iluminação para galpões de frangos de corte / Lighting systems for broiler houses
A iluminação é um importante fator para a produção avícola. O tipo de lâmpada usada nos galpões interfere diretamente na relação custo/benefício da atividade. Apesar de a lâmpada incandescente ser a mais usada, existem novas tecnologias de iluminação artificial que apresentam menor consumo de energia, porém, essas têm sido pouco utilizadas pa

16. Iluminação natural em setores de produção de edifícios industriais : estudos de caso na região metropolitana de Campinas / Daylighting in manufacturing sectors of industrial buildings : case studies in the metropolitan region of Campinas
Although daylighting is a renewable resource, clean and costless, support to energy efficiency of a built environment and promoter of wellness state and health, it is not yet used in an efficient way in industrial building design, probably because architects and its clients ignore its principles, resources and possibilities. On the other hand, one notes an i

17. Estudo da eficiência para a ventilação natural dos sheds em hospitais da Rede Sarah / Study of the efficiency of natural ventilation of sheds Sarah network in Hospitals
Natural ventilation in tropical regions is an efficient design strategy for achieving thermal comfort and reducing energy consumption. The utilization of natural resources and climate conditions improves integration of the building with its surroundings and allows comfort conditions through passive systems of conditioning. The effects of wind on a building a

18. Uma avaliação sobre características espaço-temporais baseadas em invariantes de cor para reconhecimento de ações
Local spatiotemporal feature has been proved to be a powerful tool to represent latent patterns of moving objects in video scenes. In particular, recognition of human actions has been the principal focus for various growing applications, including video indexing, content-based video retrieval, video summarization, filtering of unwanted content, rating of mov

19. Curtain color and lighting program in broiler production: I - general performance
The objective of the present study was to evaluate mortality and performance, darkling beetle population (Alphitobius diaperinus), light intensity, electrical energy consumption and economic efficiency of broilers reared under two lighting programs (nearly continuous or intermittent) and two curtain colors (yellow or blue). The experiment was conducted betwe

24. Sistema visual de segmentação de objetos robusto à iluminação para monitoramento automático de tráfego de veículos terrestres
This study presents a proposal for a moving object segmentation system that is resistant to changes in lighting conditions and can detect and suppress moving shadows. The technique of background subtraction using mixtures of gaussians provided a basis for this study. To better deal with illumination changes, that technique was adapted to use the HSV color sp
