Comparison of third-order fractional partial differential equation based on the fractional operators using the explicit finite difference method

Alexandria Engineering Journal, 2023
In this research paper, the third-order fractional partial differential equation (FPDE) in the sense of the Caputo fractional derivative and the Atangana-Baleanu Caputo (ABC) fractional derivative is investigated for the first time. The importance of the

Partial ${\cal N}=2$ Supersymmetry Breaking and Deformed Hypermultiplets [PDF]

, 2019
We study partial supersymmetry breaking from ${\cal N}=2$ to ${\cal N}=1$ by adding non-linear terms to the ${\cal N}=2$ supersymmetry transformations.

A generalization of arithmetic derivative to p-adic fields and number fields [PDF]

Notes on Number Theory and Discrete Mathematics
The arithmetic derivative is a function from the natural numbers to itself that sends all prime numbers to 1 and satisfies the Leibniz rule. The arithmetic partial derivative with respect to a prime p is the p-th component of the arithmetic derivative ...

Virtual Constant Signal Injection-Based MTPA Control for IPMSM Considering Partial Derivative Term of Motor Inductance Parameters

World Electric Vehicle Journal, 2022
The dq-axis inductance parameter value of the Internal Permanent Magnet Synchronous Motor (IPMSM) will change with the dq-axis current. The Virtual Constant Signal Injection Method (VCSIM)-based Maximum Torque Per Ampere (MTPA) control ignores the ...

Asymptotic Expansion for Harmonic Functions in the Half-Space with a Pressurized Cavity [PDF]

, 2015
In this paper, we address a simplified version of a problem arising from volcanology. Specifically, as reduced form of the boundary value problem for the Lam\'e system, we consider a Neumann problem for harmonic functions in the half-space with a cavity $

Solving Parabolic Partial Delay Differential Equations Using The Explicit Method And Higher Order Differences

Journal of Kufa for Mathematics and Computer, 2013
In this paper we use the higher order differences for second order (derivative)  in solving  parabolic partial delay differential equations by using the explicit method and we get results are more closer to the exact values than the results which can ...
