Explaining the Frequency Dependence of the DC-Biased Dielectric Response of Polar Nanoregions by Field-Enhanced Correlation Length

Autor: Jianwei Zhang, Xiaoping Du, Jiguang Zhao, Yongsheng Duan

Publikováno v: Nanomaterials, Vol 12, Iss 8, p 1293 (2022)

Understanding the effects of polar nanoregions (PNRs) dynamics on dielectric properties is a complex question of essential importance for both fundamental studies of relaxor ferroelectrics and their applications to electro-optic devices. The frequenc

Impacts of experimental advisory exit speed sign on traffic speeds for freeway exit ramp.

Autor: Yongfeng Ma, Wenbo Zhang, Xin Gu, Jiguang Zhao

Publikováno v: PLoS ONE, Vol 14, Iss 11, p e0225203 (2019)

Many crashes occur around freeway exit ramp areas in China due to excessive speeds and large speed variances. Traditionally, a single posted ramp speed limit sign is installed around the physical gore area to manage the speed. To address this issue,

Hydrodynamic Ram Effect Caused by Debris Hypervelocity Impact on Satellite Tank

Autor: Beilei Zhao, Jiguang Zhao, Cunyan Cui, Yongsheng Duan

Publikováno v: Applied Sciences, Vol 9, Iss 20, p 4200 (2019)

To study the hydrodynamic ram effect caused by the debris hypervelocity impact on the satellite tank, a numerical simulation of the spherical debris impacting the satellite tank at the velocity of 7000 m/s was carried out based on ANSYS/LS-DYNA softw

Shock Initiation of a Satellite Tank under Debris Hypervelocity Impact

Autor: Beilei Zhao, Jiguang Zhao, Cunyan Cui, Yan Wang

Publikováno v: Applied Sciences, Vol 9, Iss 19, p 3957 (2019)

For the risk assessment of a satellite to determine whether the satellite tank explodes under the hypervelocity impact, the Walker−Wasley criterion is selected to predict the shock initiation of the satellite tank. Then, the minimum power density o
