Beyond the Kinetic Chain Process in a Stroke using a Triple Pendulum Model [PDF]
, 2016 The efficient way to transfer input potential energy to the kinetic energy of a racket or bat was analyzed by two coupled harmonic triple pendulums. We find the most efficient way to transfer energy based on the kinetic chain process. Using control parameters, such as the release times, lengths and masses of the triple pendulum, we optimize the kinetic

Optimisation of the operating-power of the circuit breaker interrupter
The Journal of Engineering, 2019 To reduce the operation power of the circuit breaker interrupter, here, the operation power is divided into two parts: the arc reaction force and kinetic energy of the moving parts, then the reaction force and the reactive force work calculation method ...

An accurate theoretical formula for linear momentum, force and kinetic energy
Bibechana, 2023 The paper demonstrates that the existing mathematical formulas of linear momentum, force and kinetic energy in physics are incomplete, since such formulas have been formulated without incorporation of mass-energy equivalence relation E = mc2. Therefore,

Importance of the Doppler Effect to the Determination of the Deuteron Binding Energy [PDF]
, 1999 The deuteron binding energy extracted from the reaction ${}^1H(n,\gamma){}^2H$ is reviewed with the exact relativistic formula, where the initial kinetic energy and the Doppler effect are taken into account.

The Impact of Horizontal Resolution on Energy Transfers in Global Ocean Models
Fluids, 2017 The ocean is a turbulent fluid with processes acting on a variety of spatio-temporal scales. The estimates of energy fluxes between length scales allows us to understand how the mean flow is maintained as well as how mesoscale eddies are formed and ...

Holographic kinetic k-essence model [PDF]
Phys.Lett.B679:293-297,2009, 2008 We consider a connection between the holographic dark energy density and the kinetic k-essence energy density in a flat FRW universe. With the choice $c\geq1$, the holographic dark energy can be described by a kinetic k-essence scalar field in a certain way. In this paper we show this kinetic k-essential description of the holographic dark energy with $

Compressible Turbulence: The Cascade and its Locality
, 2011 We prove that inter-scale transfer of kinetic energy in compressible turbulence is dominated by local interactions. In particular, our results preclude direct transfer of kinetic energy from large-scales directly to dissipation scales, such as into ...

The power of microRNA regulation—insights into immunity and metabolism
FEBS Letters, EarlyView.MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...
