Effect of denoising on the quality of reconstructed images in digital breast tomosynthesis
(SPIESan Francisco, 2013-03)
Individual projection images in Digital Breast Tomosynthesis (DBT) must be acquired with low levels of radiation,
which significantly increases image noise. This work investigates the influence of a denoising algorithm ...

(Bogotá - Ciencias - Maestría en Ciencias - FísicaDepartamento de FísicaUniversidad Nacional de Colombia - Sede Bogotá, 2019-12-20)
Resumen
Este trabajo se reportan aportes hechos en la síntesis y estudio de propiedades ópticas, eléctricas, morfológicas y estructurales de películas delgadas del compuesto CsPbBr3 crecido con estructura Perovskita usando ...
A emissão do gás da região de linhas estreitas em galáxias Seyfert próximas
(Universidade Federal de Santa MariaBrasilFísicaUFSMPrograma de Pós-Graduação em FísicaCentro de Ciências Naturais e Exatas, 2017-12-21)
The Active Galactic Nuclei (AGNs) show high luminosities ( 109 L ) and emit energy from
the accretion disk around the central Supermassive Black Hole (SMBH). The Narrow Line
Region (NLR) is the only AGN structure spatially ...
The SPHERE view of the planet-forming disk around HD 100546
(ESO, 2016-04)
Context. The mechanisms governing planet formation are not fully understood. A new era of high-resolution imaging of protoplanetary disks has recently started, thanks to new instruments such as SPHERE, GPI, and ALMA. The ...
The red dwarf pair GJ65 AB: inflated, spinning twins of Proxima Fundamental parameters from PIONIER, NACO, and UVES observations
(EDP Sciences, 2016)
The nearby red dwarf binary GJ65 AB (UV + BL Ceti, M5.5Ve + M6Ve) is a cornerstone system to probe the physics of very low-mass stars. The radii of the two stars are currently known only from indirect photometric estimates, ...
Emprego da piroidrólise como método de preparo de amostras para a determinação de tungstênio em carbeto de silício por técnicas baseadas em plasma indutivamente acoplado
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2020-02-26)
In this work, pyrohydrolysis was proposed as a sample preparation method for the
tungsten volatilization of the silicon carbide (SiC) and subsequent determination by
induced coupled plasma optical emission spectroscopy ...
Spectroscopic characterisation of microlensing events: Towards a new interpretation of OGLE-2011-BLG-0417
(Edp Sciences, 2016-11)
The microlensing event OGLE-2011-BLG-0417 is an exceptionally bright lens binary that was predicted to present radial velocity variation at the level of several km s-1. Pioneer radial velocity follow-up observations with ...
