Analysis of Algorithm Efficiency for Heat Diffusion at Nanoscale Based on a MEMS Structure Investigation

open access: yesEnergies, 2020
This paper presents an analysis of the time complexity of algorithms prepared for solving heat transfer problems at nanoscale. The first algorithm uses the classic Dual-Phase-Lag model, whereas the second algorithm employs a reduced version of the model ...

LeXInt: Package for exponential integrators employing Leja interpolation

open access: yesSoftwareX, 2023
We present a publicly available software for exponential integrators that computes the φl(z)functions using polynomial interpolation. The interpolation method at Leja points have recently been shown to be competitive with the traditionally-used Krylov ...

Krylov Subspace Acceleration of Waveform Relaxation

open access: yesSIAM Journal on Numerical Analysis, 2003
In recent years, certain very old ideas of iterative algorithms traditionally used to linear algebraic problems, come back with the changed name of waveform relaxation when applied in a changed context, for example to problems of ordinary differential equations (ODEs) or partial differential equations (PDEs).

Solving Coupled Cluster Equations by the Newton Krylov Method

open access: yesFrontiers in Chemistry, 2020
We describe using the Newton Krylov method to solve the coupled cluster equation. The method uses a Krylov iterative method to compute the Newton correction to the approximate coupled cluster amplitude.

Sampling Error Analysis in Quantum Krylov Subspace Diagonalization [PDF]

open access: yesQuantum
Quantum Krylov subspace diagonalization (QKSD) is an emerging method used in place of quantum phase estimation in the early fault-tolerant era, where limited quantum circuit depth is available. In contrast to the classical Krylov subspace diagonalization

Reduced-Rank Adaptive Filtering Using Krylov Subspace

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
A unified view of several recently introduced reduced-rank adaptive filters is presented. As all considered methods use Krylov subspace for rank reduction, the approach taken in this work is inspired from Krylov subspace methods for iterative solutions ...
