Nonequilibrium Steady State in Vibrating Granular Gases [PDF]
Progress of Theoretical Physics Supplement, 2006 Statistical properties of nonequilibrium steady states in vibrating granular gases in an slightly tilted container are investigated in terms of the discrete-element method. It is found that the steady behavior of this granular flow is difficult to be described by the steady Fokker-Planck equation with Coulomb friction.

Rapidly Solidified High‐Strength Invar 36 Prepared by Planar‐Flow Melt Spinning
Advanced Engineering Materials, EarlyView.The Invar 36 alloy was rapidly solidified using the planar‐flow melt‐spinning technique. Ribbon samples with thicknesses ranging from 20 to 160 mm were produced. As the grain size of the ribbon decreased to sub‐micron levels, the hardness increased by more than 2 times.

On the Steady State Motion of Electro-Magnetic Vibrator
Transactions of the Japan Society of Mechanical Engineers, 1959 In vibratory machineries electro-magnetic vibrators are frequently used as the source of vibration. These vibrators for practical use are of moving-coil or electro-magnet type and are excited with sinusoidal or half-wave rectified current. In order to investigate the fundamental performance of vibratory machineries, the steady state motion of vibrators

Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System
Advanced Engineering Materials, EarlyView.Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.

Steady-State Oscillations in Resonant Electrostatic Vibration Energy Harvesters [PDF]
IEEE Transactions on Circuits and Systems I: Regular Papers, 2013 In this paper, we present a formal analysis and description of the steady-state behavior of an electrostatic vibration energy harvester operating in constant-charge mode and using different types of electromechanical transducers. The method predicts parameter values required to start oscillations, allows a study of the dynamics of the transient process,
