Pendulum systems for harvesting vibration energy from railroad tracks and sleepers during the passage of a high-speed train: A feasibility evaluation
(Elsevier, 2019-07)
We evaluate the feasibility of recovering energy from the passage of a high-speed train, by means of a pendulum harvester. A simple mathematical model of the parametric pendulum is employed to obtain numerical predictions, ...
Delayed Bilateral Teleoperation of the Speed and Turn Angle of a Bipedal Robot
(Cambridge University Press, 2020-07)
This paper proposes a shared control scheme which aims to achieve a stable control of the speed andturn of a bipedal robot during a delayed bilateral teleoperation. The strategy allows to get a delay-dependent damping value ...
New insights into the dynamics of swarming bacteria: A theoretical study
(Cold Spring Harbor Laboratory Press, 2016-12-18)
In the present work we simulate the basic two-dimensional dynamics of swarming E. coli bacteria on the surface of a moderately soft agar plate. Individual bacteria are modelled by self-propelled ridged bodies (agents), ...
New Insights into the Dynamics of Swarming Bacteria: A Theoretical Study
(Cornell University, 2016-12)
In the present work we simulate the basic two-dimensional dynamics of swarming E. coli bacteria on the surface of a moderately soft agar plate. Individual bacteria are modelled by self-propelled ridged bodies (agents), ...
Geometric rectification for nanoscale vibrational energy harvesting
(American Physical Society, 2018-02)
In this work, we present a mechanism that, based on quantum-mechanical principles, allows one to recover kinetic energy at the nanoscale. Our premise is that very small mechanical excitations, such as those arising from ...
Decadal predictability and prediction skill of sea surface temperatures in the South Pacific region
(Springer, 2020-05)
The South Pacific Ocean is a key driver of climate variability within the Southern Hemisphere at different time scales. Previous studies have characterized the main mode of interannual sea surface temperature (SST) variability ...
Admittance Controller with Spatial Modulation for Assisted Locomotion using a Smart Walker
(Springer, 2019-06)
Smart Walkers are robotic devices that may be used to improve the stability in people with lower limb weakness or poor balance. Such devices may also offer support for cognitive disabilities and for people that cannot ...
A self-consistent weak friction model for the tidal evolution of circumbinary planets
(EDP Sciences, 2019-07)
We present a self-consistent model for the tidal evolution of circumbinary planets that is easily extensible to any other three-body problem. Based on the weak-friction model, we derive expressions of the resulting forces ...
Dynamical impacts associated with radiation boundary conditions
(Elsevier Science, 2001-12)
It is well known that the use of radiation conditions for the non-linear shallow water equations can lead to an incorrect model response in a variety of dynamical settings. In this study, we show that conditions aimed to ...
Non-linear dynamic response of a rotating thin-walled composite beam
(Asociación Argentina de Mecánica Computacional, 2010-11)
The nonlinear planar response of a cantilever rota ting slender beam to a principal parametric resonance of its first bending mode is analyzed. The equation of motion is obtained in the form of an integro-partial differential ...
