Kinetic Energy Harvesting [PDF]
, 2008 This paper reviews kinetic energy harvesting as a potential localised power supply for wireless applications. Harvesting devices are typically implemented as resonant devices of which the power output depends upon the size of the inertial mass, the frequency and amplitude of the driving vibrations, the maximum available mass displacement and the ...

On the Bending Kinetic Energy and a Revisit to Cross-Scale Kinetic Energy Diagnostics
Ocean-Land-Atmosphere ResearchA comprehensive and accurate representation of kinetic energy (KE) is crucial for understanding multiscale processes in the Earth system. Traditional 2-reservoir frameworks, which partition total kinetic energy into mean kinetic energy (MKE) and eddy ...

A new dynamic subgrid-scale model using artificial neural network for compressible flow
Theoretical and Applied Mechanics Letters, 2022 The subgrid-scale (SGS) kinetic energy has been used to predict the SGS stress in compressible flow and it was resolved through the SGS kinetic energy transport equation in past studies.

Can the Hartree–Fock kinetic energy exceed the exact kinetic energy?
The Journal of Chemical Physics, 2022 The Hartree–Fock (HF) approximation has been an important tool for quantum-chemical calculations since its earliest appearance in the late 1920s and remains the starting point of most single-reference methods in use today. Intuition suggests that the HF kinetic energy should not exceed the exact kinetic energy; but no proof of this conjecture exists ...

Energy Dissipation in Magnetic Islands Formed during Magnetic Reconnection
The Astrophysical Journal, 2023 Magnetic reconnection converts magnetic energy into particle kinetic energy, and satellite observations have shown that 20%–50% of magnetic energy is channeled into electron kinetic energy.

Obstacle Avoidance with Kinetic Energy Buffer [PDF]
2021 IEEE International Conference on Robotics and Automation (ICRA), 2021 This paper presents Kinetic Energy Difference (KED) as a metric for collision proximity. The calculation of KED for differentially driven robots is explained, along with an example obstacle avoidance algorithm that utilizes it. This example algorithm is computationally efficient and simulations show that it is capable of guiding robots with slow ...

Kinetic energy density study of some representative semilocal kinetic energy functionals [PDF]
The Journal of Chemical Physics, 2007 There is a number of explicit kinetic energy density functionals for noninteracting electron systems that are obtained in terms of the electron density and its derivatives. These semilocal functionals have been widely used in the literature. In this work, we present a comparative study of the kinetic energy density of these semilocal functionals ...
