A substantial reduction in the mass of nonlinear energy sinks has been achieved. At the same time, the effect of vibration suppression is improved. Introducing the inertance without the mass, the equation of motion for the inertial nonlinear energy sink is established. By applying the harmonic ...
In this short communication, an enhanced nonlinear energy sink (NES) referred to as a nonlinear energy sink-inerter (NESI) is proposed. The NESI is similar to a traditional NES, except an inerter is position between the NES mass and a fixed point. The results of this study demonstrate the...
The paper introduces a novel type of nonlinear energy sink, designed as a simple rotating eccentric mass, which can rotate with any frequency and; therefore, inertially couple and resonate with any mode of the primary system. We report on theoretical and experimental investigations of targeted energ...

This results in a reduction of 67% of wind power input at near-inertial frequencies in the region of study. Wind-current feedback also provides a net energy sink for internal tides, removing energy at a rate of 0.2 mW/m2 on average, corresponding to 8% of the local internal tide ...
lacer was silenced. The PF tracked, but did not intercept the orchid bee,Euglossa dilemma. The system effectively intercepted flying vectors, but not bees, at a distance of 30 m, heralding the use of photonic energy, rather than chemicals, to control flying vectors....
Secondly, in applications like continuous monitoring, usage of static sink causes the clusters near the sink to die out faster, as the cluster heads in these clusters form the fixed path for data routing, hence resulting in hot spot problems. In this work, an energy based cluster head ...

“You are aware that the physics is invariant to the choice of the inertial frame of reference of the observer, correct? So as long as the wing is not accelerating relative to the ground, the analysis of the flow by an observer traveling along with the velocity of the wing yields the sa...
To reduce size and weight of the inertial mass required in traditional nonlinear energy sink (NES), an inerter nonlinear energy sink (INES) for suppressing thetorsional vibrationof therotor systemis developed in this paper. The INES is a combination of a NES with piecewise linear stiffness and ...
