1. Investigating Space Radiation Environment Effects on Communication of Razaksat-1
ABSTRACT: This study attempted to identify whether space radiation sources could have affected the communication on RazakSAT-1 that was orbiting in a Low Earth Orbit-Near Equatorial (LEO-NEqO). Data on galactic cosmic rays (GCR), trapped protons, trapped electrons, and solar energetic particles (SEPs) obtained from Space Environment Information System (SPENV

2. Relationship between the spectral response of sugar cane, based on AVHRR/NOAA satellite images, and the climate condition, in the state of São Paulo (Brazil), from 2001 to 2008.
The objective of this work was analyze the correlation between time series of an agroclimatic index (WRSI) and the spectral response (NDVI) of sugar cane based on images of AVHRR/NOAA satellites, in producing regions of the state of Sao Paulo (Brazil), from 2001 to 2008. The use of time series of AVHRR/NOAA images having subsequent growing seasons improved t

4. Identification of sugar cane fields in the state of sao paulo using a time series of AVHRR/NOAA satellite images.
Brazil is the first world producer of sugar cane. Despite the economic and social importance of agribusiness to Brazil, it is still difficult to estimate the harvest of the its main agricultural crops with the precision and anticipation needed, justifying the study and development of new methods based on the use of remote sensing data, for example. Even cons

5. Monitoring sugar cane crops through dtw-based method for similarity search in NDVI time series.
Brazil is an important sugar cane producer, which is the main resource for ethanol production, a renewable source of energy. Due to the strategical importance of this agricultural commodity, it is necessary to improve models that assist the crops monitoring process. Recently, remote sensing images have also been used to crops monitoring. Vegetation index ima

6. InferÃncia do Estado Geral da Umidade Superficial do Solo Pelo Ãndice de Seca Temperatura-VegetaÃÃo e por Imagens do SatÃlite NOAA-17: AplicaÃÃes no SemiÃrido do Cearà / Inference of the General State of the Surface Soil Moisture by the Temperature-Vegetation Dryness Index and NOAA-17 Satellite Images: Applications in Semiarid CearÃ
A observaÃÃo da superfÃcie terrestre por meio de satÃlites em Ãrbita de nosso planeta tornou-se corriqueira no mundo contemporÃneo. As inferÃncias de variÃveis ambientais diversas feitas a partir de imagens e dados fornecidos por satÃlites cada vez mais aumentam em qualidade e aplicabilidade de maneira que um nÃmero crescente de hidrologistas, mete

7. Evaluation of EOS/MODIS and NOAA/AVHRR sensors in the detection and reporting of fires and burnings / Avaliação dos sensores EOS/MODIS e NOAA/AVHRR na detecção e registro de incêndios e queimadas
The efficiency of detection and monitoring of fire forests is fundamental for fire control and reduction of costs and damages in firefighting operations. Therefore the need for efficient methods for forest fire detection, allowing a faster action and better decision-making. Remote sensing can be a suitable tool for preventing and fighting forest fires. The o

11. Estimativa dos componentes do balanço radiativo à superfície mediante satélites meteorológicos / Estimation of components the budget radiation surface by using meteorological satellites
The budget between incoming radiation surface and outgoing is called Budget Radiation Surface (BRS). Conventional methods of measure of this budget are prompt and therefore representative of small areas, while that the meteorological satellites allow to all have a regular covering of the globe. This thesis has as objective basic to analyze methods of estimat

12. Processamento de imagens AVHRR/NOAA visando o monitoramento de estiagem
A great part of the Brazilian territory is vulnerable to the occurrence of frequent intense dry periods since there is a difference between the precipitation and the annual potential evaporation during the year. Some methods have been proposed to assess and monitor the occurrence of a drought, such as that ones based on agroclimatic indexes calculated with g
