Autor: WEI Qiong, LU Hao, WU Zilong, BAI Linyong, ZHANG Daode, LI Yi

Publikováno v: Xibei Gongye Daxue Xuebao, Vol 42, Iss 1, Pp 138-148 (2024)

Due to the characteristics of low stiffness, low air source pressure, and easy fluid saturation of the pneumatic servo system, the energy dissipation of the system during the working process is large, the system is easily affected by friction, and th

Autor: Zhang Daode, Lingkang Wei, Xinyu Hu, Chupeng Zhang, Xuesheng Li

Publikováno v: Archives of Electrical Engineering, Vol vol. 68, Iss No 4, Pp 843-858 (2019)

Brushless DC motors are often used as the power sources for modern ship electric propulsion systems. Due to the electromagnetic torque ripple of the motor, the traditional control method reduces the drive performance of the motor under load changes.

Quantum Identity-Based Encryption from the Learning with Errors Problem

Autor: Gao, Wenhua, Yang, Li, Zhang, DaoDe, Liu, Xia

In order to prevent eavesdropping and tampering, the network security protocols use a handshake with an asymmetric cipher to establish a session-specific shared key with which further communication is encrypted using a symmetric cipher. The commonly
