Randomized Row and Column Iterative Methods with a Quantum Computer [PDF]

open access: yes, 2019
We consider the quantum implementations of the two classical iterative solvers for a system of linear equations, including the Kaczmarz method which uses a row of coefficient matrix in each iteration step, and the coordinate descent method which utilizes

Some Hyperbolic Iterative Methods for Linear Systems

open access: yesJournal of Applied Mathematics, 2020
The indefinite inner product defined by J=diagj1,…,jn, jk∈−1,+1, arises frequently in some applications, such as the theory of relativity and the research of the polarized light.

Adaptive Iterative Splitting Methods for Convection-Diffusion-Reaction Equations

open access: yesMathematics, 2020
This article proposes adaptive iterative splitting methods to solve Multiphysics problems, which are related to convection−diffusion−reaction equations. The splitting techniques are based on iterative splitting approaches with adaptive ideas.

Unambiguous range extension for pulse‐Doppler radar via Poisson disk sampling

open access: yesIET Radar, Sonar & Navigation, 2021
Since the maximum unambiguous range in the traditional single‐channel pulse‐Doppler (PD) radar is restricted by the pulse repetition interval (PRI), there is a trade‐off between the maximum unambiguous range and the maximum unambiguous velocity.

Iterative methods for k-Hessian equations

open access: yes, 2018
On a domain of the n-dimensional Euclidean space, and for an integer k=1,...,n, the k-Hessian equations are fully nonlinear elliptic equations for k >1 and consist of the Poisson equation for k=1 and the Monge-Ampere equation for k=n.

Nonlinear Preconditioning: How to use a Nonlinear Schwarz Method to Precondition Newton's Method [PDF]

open access: yes, 2015
For linear problems, domain decomposition methods can be used directly as iterative solvers, but also as preconditioners for Krylov methods. In practice, Krylov acceleration is almost always used, since the Krylov method finds a much better residual ...

An approach of extrapolation methods for the solution of nonlinear Volterra–Fredholm integral equations of the second kind [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization
This study presents the process of using extrapolation methods to solve the nonlinear Volterra–Fredholm integral equations of the second kind. To do this, by approximating the integral terms contained in equations by a quadrature rule, the nonlinear ...

Computation of saddle type slow manifolds using iterative methods [PDF]

open access: yes, 2015
This paper presents an alternative approach for the computation of trajectory segments on slow manifolds of saddle type. This approach is based on iterative methods rather than collocation-type methods.

Bandlimited Frequency-Constrained Iterative Methods

open access: yesRemote Sensing
Variable aperture sampling reconstruction matrices have a history of being computationally intensive due to the need to compute a full matrix inverse. In the field of remote sensing, several spaceborne radiometers and scatterometers, which have irregular
