Abstract: Tendon sheath mechanism (TSM) is an essential mechanical element for the implementation of flexible endoscopic systems owing to its small volume and simple structure. However, nonlinear ...

PV-PQ switching is always a difficult problem to solve in the calculation of power flow using the Newton-Raphson (N-R) method. Firstly, suitable PV buses cannot be selected for switching, making ...

Incremental Potential Contact (IPC) is for robust and accurate time stepping of nonlinear elastodynamics. IPC guarantees intersection- and inversion-free trajectories regardless of materials, ...
