Derivations of Higher Order in Prime Rings

Canadian Mathematical Bulletin, 1996
AbstractLet R be a prime ring of characteristic not 2 and d a derivation of R. It is shown that if d2n is a derivation of R, where n is a positive integer, then d2n-1 = 0.

Two-temperature thermoelastic model without energy dissipation including higher order time-derivatives and two phase-lags

Materials Research Express, 2019
In the current analysis, we have constructed a new general thermoelastic heat conduction model with two-temperature including higher order time-derivatives and two phase-lags. The thermoelastic models established by Chen and Gurtin Chen, Gurtin 1968.

A novel generalized thermoelasticity with higher-order time-derivatives and three-phase lags

, 2019
In this work, a modified thermoelastic model of heat conduction, including higher order of time derivative, is constructed by extending the Roychoudhuri model (TPL) (Choudhuri, 2007).

Instantaneous Higher Order Phase Derivatives

Digital Signal Processing, 2002
Abstract Nelson, D. J., Instantaneous Higher Order Phase Derivatives, Digital Signal Processing 12 (2002) 416–428 We present methods, based on the short time Fourier transform, which may be used to analyze the structure of multicomponent FM modulated signals instantaneously in time and frequency.

QUALITATIVE REASONING WITH HIGHER-ORDER DERIVATIVES

1990
The goals of qualitative physics are to identify the distinctions and laws which govern qualitative behavior of devices such that it is possible to predict and explain the behavior of physical devices without recourse to quantitative methods. Although qualitative analysis lacks quantitative information, it predicts significant characteristics of device

A higher order stable numerical approximation for time‐fractional non‐linear Kuramoto–Sivashinsky equation based on quintic B‐‐spline

Mathematical methods in the applied sciences
This article deals with designing and analyzing a higher order stable numerical analysis for the time‐fractional Kuramoto–Sivashinsky (K‐S) equation, which is a fourth‐order non‐linear equation.

Runge–Kutta with higher order derivative approximations

Applied Numerical Mathematics, 2000
This paper deals with a new class of Runge-Kutta methods for initial value problems \(y'= f(x,y)\). New third- and fourth-order numerical integration techniques inspired by the Runge-Kutta method are presented. These methods exploit the use of higher-order derivatives, specially \(f'\). A technique utilizing an approximation to \(f'\) is presented. The

Impact of mixed boundary conditions and nonsmooth data on layer‐originated nonpremixed combustion problems: Higher‐order convergence analysis

Studies in applied mathematics (Cambridge)
This work explores the theoretical and computational impacts of mixed‐type flux conditions and nonsmooth data on boundary/interior layer‐originated singularly perturbed semilinear reaction–diffusion problems.
