Frequency entrainment for micromechanical oscillator
Frequency entrainment micromechanical oscillator
2015/8/27
We demonstrate synchronization of laser-induced self-sustained vibrations of radio-frequency micromechanical resonators by applying a small pilot signal either as an inertial drive at the natural freq...
Perturbation analysis of entrainment in a micromechanical limit cycle oscillator
Resonance MEMS Bifurcation Perturbation

The nonlinear dynamics of micromechanical oscil-lators are explored experimentally. Devices consist of singly and doubly supported Si beams, 200nm thick and 35 μm long.When illuminated within a laser ...
Developmental acquisition of entrainment skills in robot swinging using van der Pol oscillators
van der Pol oscillator swinging robot entrainment skills degrees of freedom problem

In this study we investigated the effects of different morphological configurations on a robot swinging task using van der Pol oscillators. The task was examined using two separate degrees of freedom ...
CFD Approaches for Modelling Bubble Entrainment by an Impinging Jet
Modelling Bubble Entrainment Impinging Jet
2009/9/3
This contribution presents different approaches for the modeling of gas entrainment under water by a plunging jet. Since the generation of bubbles happens on a scale which is smaller than the bubbles,...
