A comparison of the Jacobi method, Successive Over-Relaxation (SOR), Conjugate Gradient (CG), and Preconditioned Conjugate Gradient (PCG) in solving linear systems / Allisya Farhana Azmi Hisham [PDF]

, 2023
Four iterative approaches to solve a system of linear equations are considered in this study. The four iteratives approach are Jacobi method, Successive Over Relaxation Method Conjugate Gradient and Preconditioned Conjugate Gradient.

Interfacial Redox Engineering Driven Forming‐Free Intrinsic Bipolar Switching in SiOx Memristors

Advanced Electronic Materials, EarlyView.
Redox engineering at the Sc/SiOx interface spontaneously establishes a stable oxygen‐vacancy‐rich region that preconditions the defect landscape in SiOx memristors. This facilitates controlled vacancy percolation, eliminates electroforming, and enables forming‐free bipolar resistive switching with improved switching uniformity, long endurance, and ...

Reliable Evaluation of Na‐Ion Battery Materials: Eliminating Na‐Metal Distortions

Advanced Energy Materials, EarlyView.
Na metal is highly reactive in carbonate electrolytes, forming unstable interphases and triggering parasitic reactions that distort measurements and undermine reproducibility. To enable accurate evaluation of materials for Na‑ion batteries, this work suggests that NASICON‑type counter electrodes provide a practical and stable platform for distortion ...

The numerical solution of a nonseparable elliptic partial differential equation by preconditioned conjugate gradients

, 1980
In this report the combination of an iterative technique, the conjugate gradient algorithm, with a fast direct method, cyclic reduction, is used to solve the linear algebraic equations resulting from discretization of a nonseparable elliptic partial ...

A Two‐Stage Characterization Pipeline and Open‐Source Framework for Reproducible Tactile Sensing

Advanced Intelligent Systems, EarlyView.
The same soft tactile sensor returns different numbers when embodied in different robots. This is an Embodiment Gap that no shared framework currently captures transparently. A two‐stage characterization pipeline, paired with a FAIR open‐source digital datasheet, decouples intrinsic sensor behavior from embodiment effects and condenses cross‐laboratory

Simulation of Fluid-Thermal Field in Oil-Immersed Transformer Winding Based on Dimensionless Least-Squares and Upwind Finite Element Method

Energies, 2018
In order to study the coupling fluid and thermal problems of the local winding in oil-immersed power transformers, the least-squares finite element method (LSFEM) and upwind finite element method (UFEM) are adopted, respectively, to calculate the fluid ...

Continuous Sewing Machine‐Like Suture Provides Higher Failure and Yield Load Compared to Traditional Techniques for Meniscal Root Repair in a Biomechanical Porcine Model

Arthroscopy, EarlyView.
Purpose To evaluate the biomechanical performance of the sewing machine‐like suture (SMS) technique against three established techniques (two cinch‐loop (TCL), modified Mason‐Allen (MMA), and double Mason‐Allen (DMA)) for transtibial pull‐out repair of posterior medial meniscal root tear (PMMRT) in a porcine model.

Inexact Preconditioned Conjugate Gradient Method with Inner-Outer Iteration

, 1997
An important variation of preconditioned conjugate gradient algorithms is inexact preconditioner implemented with inner-outer iterations [5], where the preconditioner is solved by an inner iteration to a prescribed precision.
