mechanical: Thekinetic energyproduced by the vibration of some objects can be harvested and transformed into electric power by using the piezoelectric mechanism in order to power sensors. Additionally, the mechanical energy produced fromturbine wheelrotation in fluids can be transformed into electric powe...
Most of the excess photonic energy that does not get converted into electricity in a PV cell is converted into heat (lattice vibration) as a consequence of thermalization and non-absorption losses. As such, cooling of the PV cells using passive and/or active heat exchanging in a CPV system...
This work presents an examination of the validity of the simple linear Landau-Teller-type model proposed by Lee for the electron-vibration energy exchange term in nitrogen [in Thermal Design of Aeroassisted Orbital Transfer Vehicles, edited by H. F. Nelson (AIAA, New York, 1985), Vol. 96,...

Furthermore, magnetostrictive materials11,14, magnetic shape memory alloys15, and triboelectrification16 have also been proposed for vibration energy harvesting. This work is linked to electrostatic energy harvesters that are based on electrically charged capacitors, the capacitance of which is varied by ...
Then by utilizing the theory of random vibration, the frequency response function of the system is obtained. This is used to derive an expression for the mean power produced by the harvester when it is subjected to broadband and band-limited stationary Gaussian white noise. The power expressions...
Corrections to thevibrational energyof spherical top molecules, diagonal in a basis of functions|v,lm⟩, can be found byperturbation theoryfrom the expandedHamiltonian(seeChapter 6: Expansion and transformations of the vibration-rotation Hamiltonian). These corrections are similar to those reported inE...
If the natural vibration frequency approaches the first-order frequency at the rated speed of the impeller, resonance and amplification of dynamic load will occur (Kallehave et al., 2015) and the whole structure can easily be damaged, which may cause heavy property losses (Huber, 1991). In ...
