Transfers between the Lagrangian points and the primaries considering radiation pressure
(2016-01-01)
The idea of the present paper is to study transfers in the restricted three-body problem considering the effects of the radiation pressure in the trajectory of the spacecraft in a bi-impulsive maneuver. Three systems of ...
TRANSFERS BETWEEN THE LAGRANGIAN POINTS AND THE PRIMARIES CONSIDERING RADIATION PRESSURE
(Univelt Inc, 2016-01-01)
The idea of the present paper is to study transfers in the restricted three-body problem considering the effects of the radiation pressure in the trajectory of the spacecraft in a bi-impulsive maneuver. Three systems of ...
Lyapunov-based low-energy low-thrust transfers to the Moon
This paper investigates the numerical computation of low-fuel low-thrust Earth-Moon transfers in a full ephemeris model incorporating the gravitational influence of the Sun, the Moon and all planets of the solar system ...
Probabilistic analysis of the active earth pressure on retaining wall for c-f soil backfill under seismic loading conditions
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2017-07-01)
This paper describes a methodology based on the Rosenblueth point estimate method to analyze the active earth pressure developed on retaining walls for c-f soil backfill under seismic loading conditions. The fundamentals ...
Projeto de contenção de talude com cortina atirantada
(Universidade Estadual Paulista (Unesp), 2021-09-22)
This thesis has as goal doing a study of the development of hypothetical tied- back, applying the concepts of resistance of reinforced concrete, orestressed anchors and also involves soil properties. All of this to prevent ...
Phase transition-like behavior of the magnetosphere during substorms
(Blackwell Publishing Ltd, 2000)
The behavior of substorms as sudden transitions of the magnetosphere is studied using the Bargatze et al. [1985] data set of the solar wind induced electric field vBs and the auroral electrojet index AL. The data set is ...
Debris perturbed by radiation pressure: relative velocities across circular orbits
(Elsevier B.V., 2004-01-01)
In the present work we consider a dynamical system of mum size particles around the Earth subject to the effects of radiation pressure. Our main goal is to study the evolution of its relative velocity with respect to the ...

Pressure-Induced Hexagonal to Monoclinic Phase Transition of Partially Hydrated CePO 4
(American Chemical Society, 2019-03)
We present a study of the pressure dependence of the structure of partially hydrated hexagonal CePO 4 up to 21 GPa using synchrotron powder X-ray diffraction. At a pressure of 10 GPa, a second-order structural phase ...
