Dual Coordination for Bilateral Teleoperation of a Mobile Robot with Time Varying Delay
(Institute of Electrical and Electronics Engineers, 2020-10)
This paper proposes a P+d like control scheme and calibration guidelines addressed to achieve stable dual coordination of force and motion in a bilateral teleoperation system of a mobile robot considering time-varying ...
A semiempirical approach to a viscously damped oscillating sphere
(IOP Publishing, 2005-12)
A simple model of damped harmonic motion is usually presented in undergraduate physics textbooks and straightforwardly applied for a variety of well-known experiments in student laboratories. Results for the decaying ...
Damping micromechanisms for bones above room temperature
(Trans Tech Publications, 2014-03)
The wide damping maximum which is reported to appear in bones, involving bothcortical and cancellous parts, between around 280 K and 420 K; has been determined to be acomposition of different processes taking place at ...
Hysteretic depinning of a particle in a periodic potential: Phase diagram and criticality
(American Physical Society, 2020-08)
We consider a massive particle driven with a constant force in a periodic potential and subjected to a dissipative friction. As a function of the drive and damping, the phase diagram of this paradigmatic model is well known ...
Electrostatically actuated encased cantilevers
(Beilstein-Institut züur Forderung der Chemischen Wissenschaften, 2018-05)
Background: Encased cantilevers are novel force sensors that overcome major limitations of liquid scanning probe microscopy. By trapping air inside an encasement around the cantilever, they provide low damping and maintain ...
Frequency–amplitude behavior in the incipient movement of grains under vibration
(Elsevier Science Inc, 2018-10)
The onset of the movement of particles placed on a horizontal rough surface subject to a vertical sinusoidal vibration is investigated through tracking experiments, theoretical analysis, and numerical simulations. The ...
Numerical stability analysis and control of umbilical-ROV systems in one-degree-of-freedom taut-slack condition
(Springer, 2007-07)
In this paper, the stability of an umbilical-ROV system under nonlinear oscillations in heave motion is analyzed using numerical methods for the uncontrolled and controlled cases comparatively. Mainly the appearance of the ...
Optimum viscoelastic absorbers for cubic nonlinear systems
(Sage Publications Ltd, 2014-07)
Dynamic vibration absorbers are efficient devices used in vibration and noise control of several mechanical systems. In recent years, some studies about these control devices comprising systems with nonlinear characteristics ...
Assessment of Reynolds-averaged Navier-Stokes method for modeling the startup regime of a Darrieus rotor
(American Institute of Physics, 2021-03)
In this article, the suitability of the Reynolds-averaged Navier-Stokes (RANS) to predict the dynamic response in the startup process of small-scale Darrieus vertical-axis wind turbines (VAWT) was investigated. Using ...
