Fast Parallel Magnetic Resonance Imaging Reconstruction Based on Sparsifying Transform Learning and Structured Low-Rank Model

Duan, Jizhong; Xu, Yuhan; Huang, Huan

2023 Journal of Shanghai Jiaotong University (Science)

doi:10.1007/s12204-023-2647-2

The structured low-rank model for parallel magnetic resonance (MR) imaging can efficiently reconstruct MR images with limited auto-calibration signals. To improve the reconstruction quality of MR images, we integrate the joint sparsity and sparsifying transform learning (JTL) into the...

Dynamic Analysis and Trajectory Solution of Multi-Robot Coordinated Towing System

Zhao, Xiangtang; Zhao, Zhigang; Wei, Qizhe; Su, Cheng

2023 Journal of Shanghai Jiaotong University (Science)

doi:10.1007/s12204-023-2649-0

Multi-robot coordinated towing system is an under-constrained system. The dynamic response of the towing system can not be fully controlled since the rope can only provide a unidirectional constraint force to the suspended object. Based on the kinematics of the multi-robot coordinated towing...
