1. Evaluation of OSEB and SEBAL models for energy balance of a crop area in a humid subtropical climate
ABSTRACT This study evaluated the adequacy of the One-Source Energy Balance (OSEB) and Surface Energy Balance Algorithm for Land (SEBAL) models to estimate evapotranspiration in grain growing areas with humid subtropical climate in Rio Grande do Sul, southern Brazil. The dataset was obtained from a micrometeorological station (Eddy Covariance) and MODIS (Mod

2. Mathematical Modeling And Numerical Simulation of Dropwise Condensation on an Inclined Circular Tube
ABSTRACT: Dropwise condensation can improve heat transfer process and, consequently, leads to considerable reduction in size and weight of condensers as well as improvement in the dehumidification process in many applications, especially in civil transport aircraft. It can also be used as an efficient cooling tool for electronics and electrical systems in ai

3. Analysis of energy fluxes and vegetation-atmosphere parameters in irrigated and natural ecosystems of semi-arid Brazil.
Knowledge on evapotranspiration is essential in quantifying water use depletion and to allocate scarce water resources to competing uses. Despite that an extensive literature describes the theoretical mechanisms of turbulent water vapour transport above and within crop canopies fewer studies have examined land surface parameters within composite landscapes o

5. EVAPOTRANSPIRAÇÃO DA MELANCIA IRRIGADA POR MEIO DO SEBAL, BALANÇO HÍDRICO E CORRELAÇÕES TURBULENTAS / ESTIMATING IRRIGATED WATERMELON EVAPOTRANSPIRATION USING SEBAL, SOIL-WATER BALANCE AND EDDY CORRELATIONS
In applications of the SEBAL (Surface Energy Balance Algorithm for Land) algorithm parameters for physical processes adjusted for other regions of the planet are commonly used. Therefore, there is a need for validation of the estimates made with the algorithm compared with other conventional methods of estimating evapotranspiration. Thus, this study main goa

6. Análise do Balanço de Calor através da superfície no Atlântico Tropical Sul por satélites. / Analysis of the Heat Budget in the South Atlantic Ocean by Satelites
O objetivo deste trabalho é investigar a variabilidade das componentes do balanço de calor pela superfície no Atlântico Sul, entre 5oS e 30oS e para o período entre 2000 a 2004, através da combinação de dados provenientes de múltiplos satélites. Com isso, visamos verificar se os processos de troca de calor no oceano são dominados por variabilidade

7. O impacto da vegetação nos microclimas urbanos / The Impact of vegetation in urban microclimates
The main purpose of this research is the effects of vegetation in urban microclimate conditions, under the premise that the presence of vegetation influences the microclimate and its surroundings. Considering different forms of green space distribution and using native species, it could quantify the intensity and spatial distribution for the microclimate eff

9. Mapeamento das estimativas do saldo de radiação e índices de vegetação em área do estado de Alagoas com base em sensores remotos. / Mapping of the estimates of the balance of radiation and indices of vegetation in an area of the state of Alagoas based on remote sensing.
The balance of radiation at the surface is of great importance in studies related to the flow of heat in the atmosphere, particularly in agricultural crops in areas and basins. This work mapped the components of the radiation balance of the land surface and vegetation indices of the area with the river basin Pratagy in Alagoas, by means of remote sensing dat
