RESUMO.O presente projeto foi desenvolvido na Faculdade de Engenharia -Unesp, Campus de Ilha Solteira, no município de Ilha Solteira, Estado de São Paulo. Estudou-se o comportamento do ambiente em duas condições de ambiente protegido, com cobertura plástica do solo e em solo nu. Avaliaram-se as médias, por quinquídio, dos valores médios, máximos e mínimos diários de temperatura e umidade relativa do ar. As médias, por quinquídio, dos: valores médios diários de déficit de saturação de vapor d'água; dos totais diários de densidade de fluxo de radiação; das transmitâncias à radiação, em cada abrigo e as regressões lineares para estimativa dos totais diários de radiação no interior dos abrigos, em função do total diário de radiação em campo aberto. O ambiente protegido reduziu em relação ao campo aberto a densidade de fluxo de radiação solar, com maior intensidade, no abrigo coberto com filme plástico térmico difusor de luz. O maior efeito dos abrigos ocorreu sobre as temperaturas máximas, tendo maiores valores a estufa coberta com filme de polietileno convencional. Não ocorreram diferenças para umidade relativa do ar entre as estufas. O mulching plástico preto aumentou a temperatura do solo a 6 e 12 cm de profundidade.Palavras-chave: polietileno, ambiência, microclima.ABSTRACT. Use of different greenhouses plastic film as cover. This project was developed in the Faculty of Engineering -Unesp, Campus of Ilha Solteira, in the municipality of Ilha Solteira -São Paulo State. We studied the environmental behavior under two conditions of protected environment, with plastic covering the soil and bare soil. It was evaluated the quinquidial averages, averages values, maximum and minimum daily temperature and relative humidity; quinquidial averages of the daily average values of deficiency of saturation of water vapor; the density of total daily flow of radiation; from transmission to radiation in each shelter and the linear regressions to estimate the total daily radiation inside the shelter, according to the daily total radiation in field open. The protected environment reduced, in relation to the open field, the density of flow of solar radiation, with higher intensity in the shelter covered with thermal plastic film lightdiffuser. The greatest effect of shelters occurred on the maximum temperature, with higher values the greenhouse covered with a conventional polyethylene film. There were no differences for air relative humidity between greenhouses. The black plastic mulching increased the soil temperature at 6 and 12 cm depth.
The application mapping on a multiprocessor platform can influence in the system performance and in the energy consumption of an embedded systems. In this context, this paper presents a meta-heuristic based approach for energy aware mapping an application into a NoC-based multiprocessor platform. The proposed approach was able to find a processor mapping that reduces the energy consumption of about 66%, in average, for the a multi-task application or a set of applications, in comparison with the worst case mapping.
