Análise cinemática e geração de trajetórias estáveis para um robô bípede antropomórfico
(Florianópolis, SC, 2012)
Development of a new kinetostatic model for humanoid robots using screw theory
(2017)
Abstract : Humanoid robots (HRs) research and development have been increasing in the world due to motion versatility of such robots and also due to the high degree of spatial and environmental adaptability provided by th ...
MODELING AND ANALYSIS OF A BALL AND BEAM SYSTEM INCLUDING IMPACTS AND DRY FRICTION
(Amer Soc Mechanical Engineers, 2014-01-01)
The Ball and Beam system is a common didactical plant that presents a complex nonlinear dynamics. This comes from the fact that the ball rolls over the beam, which rotates around its barycenter. In order to deduce the ...
Earthquake magnitude calculation without saturation from the scaling of peak ground displacement
(Amer Geophysical Union, 2015)
GPS instruments are noninertial and directly measure displacements with respect to a
global reference frame, while inertial sensors are affected by systematic offsets—primarily tilting—that
adversely impact integration ...
Seeking the local convergence depth. II. Tully-Fisher observations of the clusters A114, A119, A194, A2295, A2457, A2806, A3193, A3381, and A3744
(UNIV CHICAGO PRESS, 1998-02)
We present Tully-Fisher (T-F) observations for nine rich Abell clusters of galaxies. This is the second such data installment of an all-sky survey of similar to 50 clusters in the redshift range 0.02 less than or similar ...
And yet it moves: the dangers of artificially fixing the Milky Way center of mass in the presence of a massive large Magellanic Cloud
(Iop Publishing, 2015-04)
Motivated by recent studies suggesting that the Large Magellanic Cloud (LMC) could be significantly more massive than previously thought, we explore whether the approximation of an inertial Galactocentric reference frame ...
Observations of meteor-head echoes using the Jicamarca 50 MHz radar in interferometer mode
(European Geosciences Union (EGU), 2004-03)
We present results of recent observations of meteor-head echoes obtained with the high-power largeaperture Jicamarca 50 MHz radar (11.95◦ S, 76.87◦ W) in an interferometric mode. The large power-aperture of the system ...
Turbulencia generada por una corriente de gravedad
(Asociación de Física Argentina, 2000-12)
Estudiamos las características de las fluctuaciones del campo de velocidad en la parte delantera o cabeza de corrientes de gravedad inerciales generadas en un canal de sección rectangular. Las corrientes estudiadas tienen ...
