A Correction Method of Estimating the Pointing Error for Reflector Antenna by Jie Zhang, Jin Huang, Wei Liang, Youran Zhang, Qian Xu, Letian Yi, Congsi Wang

“…Based on the dynamic model of antenna structure and the analyzing model of pointing error, using the displacement information of sampling points on reflector, this paper proposes a correction method to achieve the purpose of accurately estimating the pointing error caused by the structural deformation. Using a 7.3-m Ka band antenna, the results show that the antenna maximum pointing error in theoretical model calculation is 0.0041° at 10m/s wind speed condition; however, the corrected pointing error would be about 0.0054° with considering the modeling error. …”

STUDY ON MECHANICAL BEHAVIOR ANALYSIS AND OPTIMIZATION OF STIFFENED RIBBED PLATE (MT) by ZHANG ChenFan, DENG QingTian, LI XinBo, HOU ZhaoYang

“…The research shows that the reinforcement effect of the plate is better than the positive distribution when the square configuration is distributed in the 45° direction, and the vertical distribution of the regular hexagon and the inner concave configuration has better plate reinforcement effect than the horizontal distribution and the 45° direction distribution; the smaller the angle between the pores of the stiffened configuration is, the better the reinforcement effect of the plate is; the use of sinusoids in the stiffened layer instead of the straight line boundary can significantly improve the bearing capacity of the stiffened plate; through the analysis of the crack path of the stiffened plate, it can be obtained that all the stiffened layers of the stiffened plate expand along the longitudinal rib wall at the load-bearing position after bending and deformation.…”

Representación histórica, televisualidad y formación ciudadana: contrastes de los biopics televisivos Sudamerican Rockers (2014) y Los Prisioneros (2020) by Consuelo Ábalos

“…This proposal contrasts the narrative strategies of two series about the same musical band, the Chilean group Los Prisioneros. Through a narratological analysis (Aumont and Marie, 2009) of the series Sudamerican Rockers (2014) and Los Prisioneros (2020), we identify the differences in the way in which the story of the same musical group is constructed and the impact that the production conditions have on the emphasis of the same “story” and its historical context.…”
