Developing CRS iterative methods for periodic Sylvester matrix equation
Advances in Difference Equations, 2019 In this paper, by applying Kronecker product and vectorization operator, we extend two mathematical equivalent forms of the conjugate residual squared (CRS) method to solve the periodic Sylvester matrix equation AjXjBj+CjXj+1Dj=Ejfor j=1,2,…,λ.

Elasto-plastic analysis of the contact region between a rigid ellipsoid and a semi-flat surface
Advances in Mechanical Engineering, 2018 When the load acting on a mechanical structure is greater than the yield strength of the material, the contact surface will undergo plastic deformation. Cumulative plastic deformation has an important influence on the lifespan of mechanical parts.

Wave-equation-based travel-time seismic tomography – Part 1: Method [PDF]
Solid Earth, 2014 In this paper, we propose a wave-equation-based travel-time seismic tomography method with a detailed description of its step-by-step process. First, a linear relationship between the travel-time residual Δt = Tobs–Tsyn and the relative ...
