The spatial damping of magnetohydrodynamic waves in a flowing partially ionised prominence plasma
, 2010 Solar prominences are partially ionised plasmas displaying flows and oscillations. These oscillations show time and spatial damping and, commonly, have been explained in terms of magnetohydrodynamic (MHD) waves. We study the spatial damping of linear non-

Effects of inertia on the steady-shear rheology of disordered solids [PDF]
, 2015 We study the finite-shear-rate rheology of disordered solids by means of molecular dynamics simulations in two dimensions. By systematically varying the damping magnitude $\zeta$ in the low-temperature limit, we identify two well defined flow regimes ...

Study of the effect of specimen size and frequency on the structural damping property of beam
Mechanical Engineering Journal, 2016 It is said that the parameters that characterize structural damping, i.e., the loss factor, are identical to the material of the specimen, but in actuality, the damping property is sometimes affected by specimen size or the frequency.

Evaluation Damping Performance for Hydrostatic Bearing Film by Damping Ratio Scaling
DEStech Transactions on Computer Science and Engineering, 2019 This paper investigates how to evaluate the damping ratio in practical measurement for hydrostatic bearing which possesses overdamped damping. The traditional methods such as decayed response, band width of resonant peak, transient response of step excitation and hysteresis circle cannot be utilized for get over overdamped behavior.

Modulating Electrochemical CO2 Reduction Pathways via Interfacial Electric Field
Advanced Functional Materials, EarlyView.Engineering interfacial electric fields in Cu/ITO electrodes enables precise control of CO2 reduction pathways. Charge transfer from Cu to ITO generates positively charged Cu species that steer selectivity from ethylene toward methane. This work demonstrates how interfacial electric‐field modulation can direct reaction intermediates and transform ...

Seismology of Standing Kink Oscillations of Solar Prominence Fine Structures [PDF]
, 2010 We investigate standing kink magnetohydrodynamic (MHD) oscillations in a prominence fine structure modeled as a straight and cylindrical magnetic tube only partially filled with the prominence material, and with its ends fixed at two rigid walls ...
