Meteor trail diffusion and fields: 2. Analytical theory
(American Geophysical Union, 2006-12-20)
A meteoroid penetrating the Earth's atmosphere leaves behind a trail of dense plasma embedded in the lower E/upper D region ionosphere. While radar measurements of meteor trail evolution have been collected and used to ...
Avaliação do desempenho do produto MSWEP no Rio Grande do Sul
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2022-04-11)
Precipitation is a meteorological variable with high spatial and temporal variability,
requiring a dense and homogeneous ground monitoring network. In Brazil, this is
challenging, due to resources scarcity for equipment ...

Evaluation of plaque composition by intravascular ultrasound ""virtual histology"": the impact of dense calcium on the measurement of necrotic tissue
(EUROPA EDITION, 2010)
Aims: We aimed to evaluate if the co-localisation of calcium and necrosis in intravascular ultrasound virtual histology (IVUS-VH) is due to artefact, and whether this effect can be mathematically estimated. Methods and ...
Precipitation field from rainfall measurements and rainfall estimates from IPMet’s radarsCampo de Precipitação Proveniente de Medidas Pluviométricas e Estimativas de Precipitação dos Radares do IPMet
(2019-01-01)
Precipitation is an essential meteorological variable in several areas of knowledge, such as agriculture, civil defense, energy, etc. However, it is a variable known to be discontinuous both in space and time. To obtain ...
Essays on Spatial Econometrics
(2012-12-22)
Esta dissertação concentra-se nos processos estocásticos espaciais definidos em um reticulado, os chamados modelos do tipo Cliff & Ord. Minha contribuição nesta tese consiste em utilizar aproximações de Edgeworth e saddlepoint ...
The infrared and molecular environment surrounding the Wolf-Rayet star WR 130
(Oxford University Press, 2015-05)
We present a study of the molecular CO gas and mid/far-infrared radiation arising from the environment surrounding the Wolf–Rayet (WR) star 130. We use the multiwavelength data to analyse the properties of the dense gas ...
Dinâmica populacional em diferentes escalas espaciais de duas espécies arbóreas da Floresta Atlântica
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Agricultura e Ambiente - PPGAA-ArCâmpus Araras, 2018-07-13)
The population dynamics of plants can be differently influenced by environmental differences in both regional and local scales. On a regional scale, population dynamics can be influenced by climate, stochastic events and ...
