Performance analysis of modeling scale on multiband oscillations in grid-connected wind farm
Frontiers in Energy Research, 2023 Grid-connected permanent magnet synchronous generator (PMSG) wind farms may be susceptible to oscillation when connected to weak grids. This paper explores the root causes of the oscillations from two perspectives: the model and the oscillation frequency

Powder Optimization Strategies for Binder Jetting Printing of BaTiO3 and Ba0,6Sr0,4TiO3 Ceramics
Advanced Engineering Materials, EarlyView.Powder optimization is investigated to enable binder jetting of BaTiO3 and Ba0.6Sr0.4TiO3 ferroelectric ceramics. The antagonistic relationship between flowability and binder compatibility is addressed through binder impregnation of granulated powders and fumed silica addition to fine powders.

LOW-FREQUENCY SWASH OSCILLATION
Doboku Gakkai Ronbunshu, 1993 Swash oscillation の周期は入射波のそれに比べて長くなることが知られている. こうした swash oscillation の長周期化を水理実験および有限振幅長波理論に基づく数値モデルにより検討し, 長周期波のほかに, swash zone での寄せ波と引き波の時系列に依存する追い付き・合体・吸収といった相互干渉によっても長周期の swash oscillation が形成されることを示した.

Nonergodic Brownian oscillator: low-frequency response
Journal of Statistical Mechanics: Theory and Experiment, 2023 Abstract An undisturbed Brownian oscillator may not reach thermal equilibrium with the thermal bath due to the formation of a localized normal mode. The latter may emerge when the spectrum of the thermal bath has a finite upper bound ω 0 and the oscillator natural frequency exceeds a critical value

Damping of low frequency pressure oscillation [PDF]
, 2007 A hydraulic line between a hydraulic pump and an actuator comes under much stress when a pulsatile actuator is used. It causes a huge pressure oscillation in the hydraulic system and thus decreases reliability.
