A Lagrange dynamic model is established based on the assumed mode method. An approach is proposed to reduce residual vibration of the flexible elevating link by optimizing acceleration of rigid link using the Pontryagin maximum principle (PMP). A numerical solution to the proposed optimization problem including a two-point boundary-value problem (2PBVP) is developed. Residual vibration of the flexible elevating link of the optimal acceleration profile is compared with that of the optimal trapezoid velocity profile. The result shows that the proposed trajectory optimization method can reduce the residual vibration more effectively.展开更多

The callers included various age groups (aged 12-7 8), different marital status, from Shanghai and outside. In total, the numbers o f men and women on hotline calls were almost same. The contents of the hotline c ounseling covered all aspects of reproductive health care; among them, the issue concerning male and female sex problems and prenatal and infant health care con stituted 26.5% and 34% respectively. Men asked questions about sex more frequent ly than women, whereas women asked questions more about baby care. Questions a bout sex problems were asked more often in the late evening until next early mor ning. Conclusions: Shanghai people showed higher needs in sexual heal th care, prenatal care and baby care. When they came across some related problem s or confusions, they would like to receive the professional instant counseling. Relevant health care programmes should be established in order to meet the fer tile-aged public's reproductive health needs.展开更多

On August 28, the hotline was connected with the provincial government's 24-hour hotline, 0898-12345.展开更多
