Wilkinson Polynomials: Accuracy Analysis Based on Numerical Methods of the Taylor Series Derivative

Desimal, 2020
Some of the numeric methods for solutions of non-linear equations are taken from a derivative of the Taylor series, one of which is the Newton-Raphson method. However, this is not the only method for solving cases of non-linear equations.

Three‐dimensional hardening‐softening elastoplastic modeling of nondilatant rock‐like materials with nonorthogonal flow rule

Deep Underground Science and Engineering, EarlyView.
A novel three‐dimensional elastoplastic constitutive model is developed for nondilatant rock‐like materials under true‐triaxial stress conditions. A piecewise yield function captures the evolution of 3D yield surfaces during hardening‐softening processes, while a fractional‐order‐controlled nonorthogonal flow rule enables flexible regulation of ...

Two Two‐Tier Stochastic Frontier Replications

Journal of Applied Econometrics, EarlyView.
ABSTRACT We replicate the two foundational studies which proposed the two‐tier stochastic frontier model, first in the cross‐sectional setting and then for the fixed effects panel data model. We explore matters of software then and now, different mathematical formulations of the likelihood, and alternative current software tools.

Analysis of Mechanical‐Electrical‐Hydraulic Coupled Vibration Response Characteristics of Thermal Control Circulating Pumps Supported by Water‐Lubricated Bearings

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

Finite‐Difference Reduced Transfer Matrix Method for Multibody Systems With Rotating Beams

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Multibody systems with rotating beams serve as critical simplified models of core components in engineering systems; however, existing analytical and numerical methods have limitations in analyzing their complex dynamic behavior. This paper proposes the Finite‐Difference Reduced Multibody System Transfer Matrix Method (FD‐RMSTMM), which ...
