High-order Energy-stable and Charge-conservative Lagrangian FEM for 3D Incompressible Inductionless MHD equations with Variable Density
Lingxiao Li, Bijie Song, Haiyan Su +1
In this paper, we consider the solution of variable-density, incompressible inductionless magnetohydrodynamic (MHD) equations with moving interface. We propose a high-order, energy…
Optimal error estimate of an isoparametric upwind discontinuous Galerkin method for radiation transport equation on curved domains
Changhui Yao, Yunpan Ma, Lingxiao Li
In recent years, high-order finite element methods on high-order meshes have attracted considerable attention. This work investigates the isoparametric upwind discontinuous Galerki…
Parametric charge-conservative mixed finite element method for 3D incompressible inductionless MHD equations on curved domains
Xue Jiang, Lei Li, Lingxiao Li
This paper develops a charge-conservative mixed finite element method with optimal convergence rates for the stationary incompressible inductionless MHD equations on three-dimensio…
A divergence-free parametric finite element method for 3D Stokes equations on curved domains
Lingxiao Li, Haiyan Su, He Zhang +1
The Stokes equations play an important role in the incompressible flow simulation. In this paper, a novel divergence-free parametric mixed finite element method is proposed for sol…
radarODE: An ODE-Embedded Deep Learning Model for Contactless ECG Reconstruction from Millimeter-Wave Radar
Yuanyuan Zhang, Runwei Guan, Lingxiao Li +3
Radar-based contactless cardiac monitoring has become a popular research direction recently, but the fine-grained electrocardiogram (ECG) signal is still hard to reconstruct from m…
