On the ADI method for Sylvester equations

open access: yesJournal of Computational and Applied Mathematics, 2009
This paper is concerned with numerical solutions of large scale Sylvester equations AX − XB = C, Lyapunov equations as a special case in particular included, with C having very small rank. For stable Lyapunov equations, Penzl (2000) and Li and White (2002) demonstrated that the so called Cholesky factored ADI method with decent shift parameters can be ...

On the ADI method for the Sylvester Equation and the optimal-$\mathcal{H}_2$ points [PDF]

open access: yesarXiv.org, 2012
The ADI iteration is closely related to the rational Krylov projection methods for constructing low rank approximations to the solution of Sylvester equation.

Polarimetric Stationarity Omnibus Test (PSOT) for Selecting Persistent Scatterer Candidates with Quad-Polarimetric SAR Datasets

open access: yesSensors, 2020
In the traditional single polarimetric persistent scatterers interferometric (PSI) technology, the amplitude dispersion index (ADI) is usually used to select persistent scatterer candidates (PSC).

ADI Methods for Three-dimensional Fractional Diffusions

open access: yesInternational Journal of Computers and Communications, 2022
ADI methods can be generalized to solve numerically multidimensional fractional diffusion equations, which describe fluid flows through porous media better than classical diffusion equations. A new, unconditionally stable, second-order and well balanced in space, third-order in time ADI scheme has been constructed and its convergence accelerated by an ...

Socioeconomic Deprivation and Vocal Handicap in Adults With Voice Disorders. [PDF]

open access: yesLaryngoscope
This study examined the relationship between socioeconomic deprivation and quality of life as measured by the Voice Handicap Index (VHI) in adults with voice disorders. Patients living with socioeconomic deprivation experienced greater voice‐related handicap from voice disorders than those from more affluent backgrounds, even when controlling for ...

An ADI Method for the Numerical Solution of 3D Fractional Reaction-Diffusion Equations

open access: yes, 2020
A numerical method for solving fractional partial differential equations (fPDEs) of the diffusion and reaction–diffusion type, subject to Dirichlet boundary data, in three dimensions is developed.

Parallel implementation of Thomas algorithm for the 2D heat equation

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2019
In this paper was considered a parallel implementation of the Thomas algorithm for the 2D heat equation. MPI was chosen as the technology for parallelization. The numerical solution of the two-dimensional heat conduction problem was solved using the two

Microstructure and mechanical properties of manganese-alloyed austempered ductile iron produced by novel modified austempering process

open access: yesCogent Engineering, 2022
Austempered ductile iron (ADI) has numerous applications because it is lightweight and has excellent mechanical properties. However, although the ADI obtained by the traditional austempering process possesses high strength and hardness, it has low ...
