Identification of mechanisms of ion induced electron emission by factor analysis
(Elsevier Science, 2005-04)
Introducing the use of the Factor Analysis method to analyze electron emission spectra we identify different mechanisms for electron emission from clean Al surfaces under bombardment by Ar+ and Li+ ions. The analysis of ...
Analysis of the influence of baffles and shields on the cooling of a digital transmission equipment
(Institute of Electrical and Electronics Engineers (IEEE), 1996-01-01)
In this work design criteria for cooling of electronic systems used in a digital transmission equipment are considered. An experimental study using a simulated electronic equipment in which vertically oriented circuit ...
Predicting the performance of the inter-Coulombic electron capture from single-electron quantities
(IOP Publishing, 2019-11-01)
The probability of the inter-Coulombic electron capture (ICEC) is studied for nanowire-embedded quantum-dot pairs where electron capture in one dot leads to electron emission from the other. Previous studies pointed to an ...

Wannier threshold theory for the description of the two-electron cusp in the ion-induced double ionization of atoms
(Elsevier, 2016-02-15)
The double electron capture into the continuum states of the projectile (double ECC) is investigated theoretically in collisions of 100 keV He2+ ions with He atoms. The process is described within the framework of the ...

Metodología para la generación de mapas tridimensionales a partir de fotogrametría con vehículo aéreo no tripulado
(Instituto Tecnológico de Costa Rica, 2016)
Costa Rica is a country with many natural resources, where the economic development is linked to the agricultural production. Therefore, the loss of nutrients and problems related to erosion has a high impact. Some of the ...
