Photoluminescence of radial heterostructured GaAs/AlGaAs/GaAs nanowires
(American Institute of Physics - AIPCollege Park, 2013-02)
Photoluminescence (PL) of high-density GaAs nanowires (NWs) encapsulated by a double AlGaAs/GaAs shell is studied. Two lines are found and assigned to the radiative recombinations of photoexcited electrons confined in the ...
Desarrollo y solución computacional de un modelo electrostático para celdas solares de nanoalambres de unión radial
(Universidad Nacional de ColombiaManizales - Ciencias Exactas y Naturales - Maestría en Ciencias - FísicaFacultad de Ciencias Exactas y NaturalesManizales, ColombiaUniversidad Nacional de Colombia - Sede Manizales, 2022)
En este trabajo, se presenta el desarrollo un modelo electrostático general para
heterouniones de nanoalambres de unión radial resolviendo la ecuación de Poisson en coordenadas cilíndricas. A diferencia de las homouniones ...
Representación femenina en los spots audiovisuales de la campaña Belleza Real de DOVE
(PUCE-Quito, 2018)
El eje central de la presente investigación es el modo en el cual la marca DOVE comunica la forma de representar a la mujer dentro de los tres spots seleccionados de la Campaña publicitaria por la Belleza Real: “¿Marchita ...
Propostas de modelagem matemática para o problema de restauração de sistemas de distribuição de energia elétrica radiais
(Universidade Estadual Paulista (Unesp), 2014-06-06)
This work presents proposals of mathematical modeling to optimize the restoration problem of radial distribution electrical systems. The restoration problem consists in strategies of topological reconfiguration of the ...
The empty primordial asteroid belt
(Amer Assoc Advancement Science, 2017-09-01)
The asteroid belt contains less than a thousandth of Earth's mass and is radially segregated, with S-types dominating the inner belt and C-types the outer belt. It is generally assumed that the belt formed with far more ...
Use of generalized hypergeometric functions in analytic stellar models
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 1989)
The present paper deals with the technique of integration theory of special functions applied to two simple analytic stellar models. We consider two cases, one with a non-linear dependence of the radial density and the ...
Macroscopic growth of filamentous fungi on solid substrate explained by a microscopic approach
(JOHN WILEY & SONS INC, 1999)
A quantitative model predicting biomass growth an solid media has been developed. The model takes into account steric interactions between hyphae and tips at the microscopic level (competition for substrate and tip-hypha ...
Kinematic properties of the field elliptical NGC 7507
(Edp Sciences, 2012-02)
The dark matter (DM) halos of field elliptical galaxies have not been well-studied and their properties appear controversial in the literature. While some galaxies appear to be nearly devoid of DM, others show clear evidence ...
