Factores relevantes de la inestabilidad del mercado petrolero
(Universidad Externado de Colombia, 2021-07-01)
El mercado petrolero es inestable e impredecible debido al impacto de los elementos politicos, militares, tecnologicos y climaticos. La nueva y estrecha relación con el mercado inanciero, en particular con los mercados a ...
Computation of the electron beam quality kQ,Q0 factors for the NE2571, NE2571A and NE2581A thimble ionization chambers using PENELOPE
(ASSOCIAZIONE ITALIANA DI FISICA MEDICA, 2017-06-01)
The quality correction factor kQ,Q0 for electron beams was calculated for three thimble ionization chambers, namely, NE2571, NE2571A and NE2581A. The Monte Carlo code PENELOPE was used to estimate the overall correction ...

Electron beam quality kQ,Q0 factors for various ionization chambers: A Monte Carlo investigation with PENELOPE
(INSTITUTE OF PHYSICS PUBLISHING, 2014-11-07)
In this work we calculate the beam quality correction factor kQ,Q0 for various plane-parallel ionization chambers. A set of Monte Carlo calculations using the code penelope/penEasy have been carried out to calculate the ...
On designing linearly tunable high-Q OTA-C filters with low sensitivity
(2004-09-07)
This paper discusses a design approach for a high-Q low-sensitivity OTA-C biquad bandpass section. An optimal relationship is established between transconductances defining the differenceβ - γ in the Q-factor denominator, ...
