Envelope-Based Variable-Gain Control Strategy for Vibration Suppression of Solar Array Using Reaction Wheel Actuator by Song Wu, Guoan Tang, Bifa Chen

“…Changing the gain coefficient to be inversely proportional to the envelope function of vibration, a variable-gain control strategy is proposed to improve the damping effect of the RW actuator. Simulation results show that the vibration suppression performance of the RW actuator is improved compared to the constant-gain control. …”

Characteristics of Low Reynolds Number Shear-Free Turbulence at an Impermeable Base by W. H. M. Wan Mohtar, A. ElShafie

“…Both velocity components sharply decreased towards zero at a distance of ≈1/3 of the integral length scale above the base due to viscous damping. The lower limit where Rel obeys the standard profile was found to be within the range 114≤Rel≤116.…”

Investigation of the lateral performance of trapezoidal double corrugated steel shear walls with two different corrugation angles by Yuanyuan Hu, Xianhui Yan

“…The obtained results have shown that the change in the angle of one of the double corrugated plates has no significant effect on the shape of the hysteresis curve and the amount of equivalent viscous damping. Nonetheless, it can lead to a change in the value of maximum resistance and energy absorption. …”

Investigation on Mercury Reemission from Limestone-Gypsum Wet Flue Gas Desulfurization Slurry by Chuanmin Chen, Songtao Liu, Yang Gao, Yongchao Liu

“…Secondary atmospheric pollutions may result from wet flue gas desulfurization (WFGD) systems caused by the reduction of Hg2+ to Hg0 and lead to a damping of the cobenefit mercury removal efficiency by WFGD systems. …”

Mathematical Modeling and Analysis of Drill String Longitudinal Vibration with Lateral Inertia Effect by Jialin Tian, Chunming Wu, Lin Yang, Zhi Yang, Gang Liu, Changfu Yuan

“…The researches show that the smaller the length of the drill string, the greater the cross-sectional area of the drill string, the greater the damping coefficient of bottom hole on the bottom of the drill string, and the more evident the effect on the dynamic stiffness of the drill string with lateral inertia effect. …”

Analysis and Experimental Verification of New Power Flow Control for Grid-Connected Inverter with LCL Filter in Microgrid by Herong Gu, Yajuan Guan, Huaibao Wang, Baoze Wei, Xiaoqiang Guo

“…In this paper, the small-signal model of the power flow control for the grid-connected inverter is established, from which it can be observed that the conventional power flow control may suffer from the poor damping and slow transient response. While the new power flow control can mitigate these problems without affecting the steady-state power flow regulation. …”

Vortical waves in a quantum fluid with vector, axial and helical charges. II. Dissipative effects by Sergio Morales-Tejera, Victor E. Ambruş, Maxim N. Chernodub

“…On the other hand, usual dissipative effects, such as charge diffusion, lead to significant damping of ultraviolet modes. We end this paper with a discussion of the regimes where these vortical waves may propagate.…”

Psychopathology of Time in Brain Disease and Schizophrenia by John Cutting, Herta Silzer

“…A review of the literature on the effect of brain damage revealed that some phenomena (déjà vu, reduplication of time, altered tempo to events) were linked with right hemisphere dysfunction, one phenomenon (incorrect sequencing of events) was linked with left anterior brain damage, and others (disrupted “biological clock”, disturbed serise of rate of flow of current or past events) could arise from subcortical as well as focal cortical damage. …”
