Three-dimensional instantaneous orbit map for rotor-bearing system based on a novel multivariate complex variational mode decomposition algorithm

no code implementations29 Jul 2021 Xiaolong Cui, Jie Huang, Chaoshun Li, Yujie Zhao

It can simultaneously extract the forward and backward components of multiple bearing sections and realize non-stationary complex signal decomposition of multiple bearing sections of the rotor.

Accelerate the Warm-up Stage in the Lasso Computation via a Homotopic Approach

no code implementations26 Oct 2020 Yujie Zhao, Xiaoming Huo

At the same time, each surrogate function is strictly convex, which enables a provable faster numerical rate of convergence.
