Microphysical parameters retrieval by cloud radar and comparing with aircraft observation in stratiform cloud

Liping,Zong Rong,Qi Yanbin,Liu Jian

Strategic Study of CAE 2012, Volume 14, Issue 9,   Pages 64-71

Abstract:

The relationships among reflectivity, velocity and spectrum width of stratiform cloud are simulated, and the availability of cloud radar data are analyzed. The reflectivity, velocity and spectrum width observed by cloud radar in vertical observation model are used to retrieve the liquid water content and the size distribution in stratiform cloud under the assumption of neglecting the air vertical speed and turbulence. The results show that the relationships among reflectivity, velocity and spectrum width observed by 8 mm cloud radar are similar to simulated values. The mean drop size, toll drop number and liquid water contend have obvious variations from cloud top to reflectivity center. The increase of reflectivity is due to the increase of drop size. The microphysical parameters retrieved by cloud radar have similar range with that by aircraft.

Fall preventive gait trajectory planning of a lower limb rehabilitation exoskeleton based on capture Research Article

Mei-ying Deng, Zhang-yi Ma, Ying-nan Wang, Han-song Wang, Yi-bing Zhao, Qian-xiao Wei, Wei Yang, Can-jun Yang,ycj@zju.edu.cn

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 10,   Pages 1322-1330 doi: 10.1631/FITEE.1800777

Abstract: We study the balance problem caused by forward leaning of the wearer’s upper body during rehabilitation training with a lower limb rehabilitation exoskeleton. The instantaneous is obtained by modeling the human-exoskeleton system and using the theory. By comparing the stability region with instantaneous s of different gait phases, the balancing characteristics of different gait phases and changes to the equilibrium state in the gait process are analyzed. Based on a model of the human-exoskeleton system and the condition of balance of different phases, a trajectory correction strategy is proposed for the instability of the human-exoskeleton system caused by forward leaning of the wearer’s upper body. Finally, the reliability of the trajectory correction strategy is verified by carrying out experiments on the Zhejiang University . The proposed trajectory correction strategy can respond to forward leaning of the upper body in a timely manner. Additionally, in the process of the center of gravity transferred from a double-support phase to a single-support phase, the ratio of gait cycle to zero moment point transfer is reduced correspondingly, and the gait stability is improved.
