Fixing two eigenvalues by a minimal perturbation
Linear Algebra and its Applications, 2005 The author presents a generalization of the optimal perturbation \(\Delta M\) to a given matrix \(M\) (in the sense that \(\|\Delta M\|_2\) is minimal such that \(M-\Delta M\) has a given eigenvalue \(\lambda_0\)), namely: finding \(\|\Delta M\|_2\) optimal perturbation of \(M\) such that \(M-\Delta M\) has two given eigenvalues \(\lambda_0\) and ...

IET Power Electronics, EarlyView., 2022 This paper introduces the research on the inductance‐capacitor‐capacitor‐inductance grid‐connected inverter using active disturbance rejection and grid voltage feedforward coordinated control technology. The pade approximation is performed on the inductance‐capacitor‐capacitor‐inductance filter to derive the first‐order discretization mathematical ...

European Eating Disorders Review, EarlyView.ABSTRACT Objective Social media use can negatively impact both physical and mental well‐being by influencing aspects like body image and potentially leading to eating disorders. This issue is particularly significant during pregnancy, a time when maternal and foetal health are heavily influenced by nutrition. This study aims to examine how social media

On the Behavior of Two C1 Finite Elements Versus Anisotropic Diffusion
International Journal for Numerical Methods in Fluids, EarlyView.Bi‐cubic Hemite‐Bézier and reduced cubic Hsieh‐Clough‐Tocher finite elements, of class C1, are compared for the solution of a highly anisotropic diffusion equation. They are tested numerically for various ratios of the diffusion coefficients on different meshes, even aligned with the anisotropy.

Error analysis of householder transformations as applied to the standard and generalized eigenvalue problems [PDF]
Backward error analyses of the application of Householder transformations to both the standard and the generalized eigenvalue problems are presented. The analysis for the standard eigenvalue problem determines the error from the application of an exact ...
