Innovative adaptation of coagulation-sedimentation-filtration process in lightly polluted urban rivers with seasonal high turbidity by Yujie Yuan, Tao Zhang, Yaqian Zhao, Yuan Liu, Song He, Yamei Cai, Yuanbo Liu, Shu Wang

“…Furthermore, the system was capable of adapting to flow variations during the rainfall events by adjusting the surface load. These findings are of great significance for the in-depth comprehension of urban river pollution dynamics in the plain area and provide effective scientific and technological support for the remediation of such lightly-polluted river with high turbidity.…”

Tibiofemoral Joint Contact Force Estimation Based on OpenSim Musculoskeletal Modeling by WANG Xiaoling, JIAN Jiawei, XIE Qiurong, LIAN Zhanghui, GUO Chunming, GUO Jiemei, LI Yurong

“…Based on the generic model gait2392 in the OpenSim model library, a new model was built, which contained 28 joints and 43 degrees of freedom, adjusted the knee joint structure to have 3 directional degrees of freedom in flexion-extension, adduction-abduction, and internal-external rotation, added an upper limb structure with 4 joints and 7 degrees of freedom in a single arm capable of torque actuation, and adjusted the contact point of the tibiofemoral joint from a single to a double contact point.Through the model scaling, inverse kinematics, inverse dynamics analysis, residual reduction processing and muscle control and analysis, the medial and lateral tibiofemoral contact forces were estimated during walking gait, comprehensively considering the contributions of external forces and internal muscle strength. …”
