Determination of onboard coplanar orbital maneuvers with orbits determined using GPS
(2012-10-01)
In the present paper a study is made in order to find an algorithm that can calculate coplanar orbital maneuvers for an artificial satellite. The idea is to find a method that is fast enough to be combined with onboard ...
Modular mathematical model for a low-speed maneuvering simulator
(ASMESan Francisco, 2014-06-08)
This paper presents the mathematical model of the real-time ship simulator for low-speed maneuvering developed by the University of São Paulo, Transpetro and Petrobras, with the technical collaboration of Brazilian Pilots ...
An abbreviated diagostic maneuver for posterior benign positional paroxysmal vertigo
(Frontiers Research Foundation, 2016)
Introduction
Benign paroxysmal positional vertigo (BPPV) secondary to canalolithiasis of the posterior semicircular canal is perhaps the most frequent cause of vertigo and dizziness. One of its properties is a high ...

Introduction
Benign paroxysmal positional vertigo (BPPV) secondary to canalolithiasis of the posterior semicircular canal is perhaps the most frequent cause of vertigo and dizziness. One of its properties is a high ...
A numerical mapping of energy gains in a powered Swing-By maneuver
(Springer, 2017-07-01)
The present paper studies the effects of a powered Swing-By maneuver, considering the particular and important situations where there are energy gains for the spacecraft. The objective is to map the energy variations ...
An abbreviated diagostic maneuver for posterior benign positional paroxysmal vertigo
(Frontiers Media, 2016-07)
Introduction: Benign paroxysmal positional vertigo (BPPV) secondary to canalolithiasis of the posterior semicircular canal is perhaps the most frequent cause of vertigo and dizziness. One of its properties is a high response ...
A Chair-based Abbreviated Repositioning Maneuver (ChARM) for fast treatment of posterior BPPV
(Springer Verlag, 2019)
© 2019, Springer-Verlag GmbH Germany, part of Springer Nature.Purpose: To assess the effectiveness of a variation of the Epley maneuver, which we have titled “Chair-based Abbreviated Repositioning maneuver (ChARM)”, in ...
Conduct after Epley`s maneuver in elderly with posterior canal BPPV in the posterior canal
(ASSOC BRASILEIRA OTORRINOLARINGOLOGIA & CIRURGIA CERVICOFACIAL, 2010)
Benign Paroxysmal Positional Vertigo is the most common peripheral vestibular disorder, especially in the elderly and presents as the predominant etiology in this population of the degeneration of the utricular macula. ...
Atmospheric close approaches with the Earth considering drag and lift forces
(2016-10-01)
A maneuver called “Aero-Gravity Assisted” is known in the literature to increase the energy gains given by a close approach between a spacecraft and a planet using the atmosphere of the planet. In a sequence of studies ...
Using low Lift-to-Drag spacecraft to perform upper atmospheric Aero-Gravity Assisted maneuvers
(Elsevier, 2022-05-21)
The Gravity Assisted Maneuver has been applied in lots of space missions, to change the spacecraft heliocentric velocity vector and the geometry of the orbit, after the close approach to a celestial body, saving propellant ...
