High Voltage, EarlyView.ABSTRACT The emergence of (ultra)wide bandgap ((U)WBG)‐based devices has significantly enhanced performance in high‐frequency switching applications, enabling breakthroughs in electric transportation, aerospace, and renewable energy systems. However, it also presents considerable challenges to insulation systems, such as electric motor winding ...

An IMEX scheme combined with Richardson extrapolation methods for some reaction-diffusion equations [PDF]
, 2013 An implicit-explicit (IMEX) method is combined with some so-called Richardson extrapolation (RiEx) methods for the numerical solution of reaction-diffusion equations with pure Neumann boundary conditions.

Applied Sciences, 2018 The atmospheric stability and ground topography play an important role in shaping wind-speed profiles. However, the commonly used power-law wind-speed extrapolation method is usually applied, ignoring atmospheric stability effects. In the present work, a

Richardson extrapolation of iterated discrete projection methods for eigenvalue approximation
, 2009 In this paper, the eigenvalue approximation of a compact integral operator with a smooth kernel is discussed. We propose asymptotic error expansions of the iterated discrete Galerkin and iterated discrete collocation methods, and asymptotic error ...

What Do Analyst Financial Modelling Mistakes Tell Us? Evidence from the Properties of Accounting
Abacus, EarlyView.This study develops a novel measure of sell‐side analyst financial modelling mistakes, based on whether an analyst's simultaneous forecasts of earnings, book value of equity, and dividends are internally consistent with the accounting clean surplus relation. I find that the discrepancy of an analyst's forecasts from clean surplus (a proxy for financial

Investigation of a Two-Grid Method of Improved Accuracy for the Elliptic Reaction–Diffusion Equation with Boundary Layers [PDF]
Учёные записки Казанского университета: Серия Физико-математические науки, 2015 A two-grid method for the elliptic equation with a small parameter ε multiplying the highest derivative is investigated. The ε-uniformly convergent difference scheme on the Shishkin mesh is considered.

On the numerical solutions of two-dimensional scattering problems for an open arc
Boundary Value Problems, 2020 For the scattering problems of acoustic wave for an open arc in two dimensions, we give a uniqueness and existence analysis via the single layer potential approach leading to a system of integral equations that contains a weakly singular operator.
