VibrationVEHDRenewable EnergyThis paper aimed to provide an overview on a potential source of renewable energy, and take advantage of the wasted energy produced by the vibration of an electric generator. A system called VEHD or Vibration Energy Harvesting Device was designed to harness this ...
Corrections to the vibrational energy of spherical top molecules, diagonal in a basis of functions |v,lm⟩, can be found by perturbation theory from the expanded Hamiltonian (see Chapter 6: Expansion and transformations of the vibration-rotation Hamiltonian). These corrections are similar to those...
transmission tower-line system by using MR dampers.The observations from numerical investigation indicate that the wind-induced vibration of transmission tower-line system can be substantially suppressed and the proposed energy evaluation criteria can be effectively utilized in the examination on control ...

In passive vibration isolation, a bistable composite plate can be used to generate high-static low-dynamic stiffness, and in vibratory energy harvesting, when used with piezoelectric film flexing, the bistable composite plate can enhance the performance via snap-through motion. In the present work,...
Because of the absence of liquid working fluid, resorption system has good adaptation to shocks and vibration circumstances, which is very favorable for applications in locomotives, boats, and even in spacecrafts [96]. Moreover, since it involves two or more reactive salts it exhibits appreciable...
3d. Under the dynamic loads produced by moving vehicles, vibration of the bridge is unavoidable, and the vibrational energy can be harvested and converted by the bricks to supply electrical power for a network of sensors monitoring the structural health of the bridge. Experimental setup In order ...
Vibration energy harvesters scavenge energy from mechanical vibrations to energise low power electronic devices. In this work, we report on vibration energy harvesting scheme based on the charging phenomenon occurring naturally between two bodies with di
The shaker was controlled by an LDS Comet vibration controller and the output from the controller was amplified using a power amplifier (LDS PA 1000 L) before feeding to the shaker. Different vibrational accelerations (0.02–1.6 g) with a frequency range of 10 Hz to 90 Hz in ...
(1) direct transitions where the momentum of the resulting electron–hole pair is very close to zero, and (2) indirect transitions where the resulting electron–hole pair has a finite momentum. The latter transitions require the assistance of a phonon (quantum of lattice vibration). Thus there...
