Rendimiento de la técnica de acceso múltiple no ortogonal en un sistema de comunicación móvil Long-Term Evolution
(Universidad Nacional de Chimborazo, 2020)
Desempenho de redes cooperativas full-duplex baseadas em NOMA e seleção parcial de relays
(Universidade Estadual Paulista (Unesp), 2018)
With the rapidly increasing demand for wireless-based applications and services, the need to efficiently exploit the radio spectrum is imperative. In addition, fifth-generation (5G) networks must satisfy some requirements ...
Interaction of shockwaves with infected kidney stones: Is there a bactericidal effect?
(2008)
Background and Purpose: Many calculi contain bacteria, which can remain active inside kidney stones and cause infection after lithotripsy. Reduction in renal infections after extracorporeal shockwave lithotripsy has been ...
Production of Thermostable Lipase by Thermomyces lanuginosus on Solid-State Fermentation: Selective Hydrolysis of Sardine Oil
(2014)
A naturally immobilized biocatalyst with lipase activity was produced by Thermomyces lanuginosus on solid-state fermentation with perlite as inert support. Maxima lipase activities (22 and 120 U/g of dry matter, using ...
High sensitivity fiber laser temperature sensor
(2015)
This paper presents an erbium-doped fiber laser temperature sensor, which is based on an intracavity fiber filter immersed in glycerol/water solutions. The sensing element is the intracavity fiber filter, consisting of a ...
Diffracto-astrometry measurements: Kinematics of the orion trapezium
(2014)
Using the historical database of the Washington Double Star Catalog (WDS) and astrometric data obtained by applying the Diffracto-Astrometry (DiAs) technique to Hubble Space Telescope Wide Field Planetary Camera 2 (HST/WFPC2) ...

Diffracto-astrometry measurements: The technique
(2014)
We investigate the possibility of performing precision astrometry on saturated stellar images of the Hubble Space Telescope (HST) Wide Field Planetary Camera 2 (WFPC2). We obtain the position of the stellar photocentres ...
Electron detachment cross sections of CH4 - colliding with O2 and N2 below 10 keV energies
(2014)
Negative methane is an interesting molecular anion from a fundamental point of view and also because it can be a source of thermal electrons in low temperature hydrocarbon plasma. Measurements of collisional electron ...
