Tidal Energy Dissipation [PDF]

Nature, 1917
IN regard to my estimate of viscous dissipation of oceanic energy in its bearing on the slowing of the earth's rotation (Proc. Roy. Soc., A, 93, p. 348), I quite assent to Mr. Jeffreys's position (NATURE, vol. xcix., p. 405, July 19, 1917) that it is still open to doubt whether the viscosity of the ocean causes a very appreciable part of the earth's ...

The free energy cost of reducing noise while maintaining a high sensitivity

, 2015
Living systems need to be highly responsive, and also to keep fluctuations low. These goals are incompatible in equilibrium systems due to the Fluctuation Dissipation Theorem (FDT).

Energy Evolution and Mechanical Features of Granite Subjected to Triaxial Loading-Unloading Cycles

Advances in Civil Engineering, 2019
Energy evolution varies during the whole process of rock deformation, and mechanical parameters are markedly altered under cyclic loading and unloading.

Energy Dissipation in Fractal-Forced Flow [PDF]

, 2006
The rate of energy dissipation in solutions of the body-forced 3-d incompressible Navier-Stokes equations is rigorously estimated with a focus on its dependence on the nature of the driving force.

Rail hidden damage detection based on the modal curvature differences method

Advances in Mechanical Engineering
The rail hidden damage includes rail bottom and rail jaw cracks, which cannot be easily detected during the early development stage, and pose a significant danger and risk of rail-breaking accidents. This paper proposed an effective method to detect rail

Excess energy and photosynthesis: responses to seasonal water limitations in co-occurring woody encroachers of the semi-arid Southern Great Plains

Photosynthetica, 2023
Woody plant areal encroachment is pervasive throughout the Southern Great Plains, USA. The ability of woody plants to dissipate excess solar radiation - dynamically over the day and sustained periods without recovery overnight -is key for maintaining ...

Energy flows in vibrated granular media

, 1998
We study vibrated granular media, investigating each of the three components of the energy flow: particle-particle dissipation, energy input at the vibrating wall, and particle-wall dissipation.

Energy dissipation prediction of particle dampers [PDF]

, 2009
This paper presents initial work on developing models for predicting particle dampers (PDs) behaviour using the Discrete Element Method (DEM). In the DEM approach, individual particles are typically represented as elements with mass and rotational ...

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control

Advanced Engineering Materials, EarlyView.
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

Experimental study on energy dissipation and fragmentation characteristics of gas-bearing coal under combined dynamic and static loading

Meitan xuebao
To explore the energy dissipation and fragmentation characteristics of gas-bearing coal under combined dynamic and static load, the impact experiment of gas-bearing coal under different impact velocities and axial compressive stress ratios was carried ...
