Series Transformer Inrush Current Reduction in DVR Using Metaheuristic Optimisation Algorithms in Presence of Balanced and Unbalanced Voltage Sags

open access: yesIET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
In this paper, a PI controller is improved for DVR to compensate voltage drops and reduce the series transformer inrush current effectively. The controller parameters are optimised using the modified arctic puffin optimisation (MAPO) algorithm in order to improve the performance of DVR.

Phase‐Lag Integro‐Partial Differential Equation: Local and Nonlocal Solutions

open access: yesAdvances in Mathematical Physics, Volume 2026, Issue 1, 2026.
Nonlocal information, such as material deformation, genetic genes, or the history of the disease, are essential as they provide us with additional details that increase the numerical solution’s accuracy. With the help of the phase delay, we may also predict the future of the phenomena we are researching.

Tau approximate solution of weakly singular Volterra integral equations

open access: yesMathematical and Computer Modelling, 2013
Abstract In this paper, we present a numerical solution of weakly singular Volterra integral equations including the Abel’s equations by the Tau method with arbitrary polynomial bases. The Tau method produces approximate polynomial solutions of differential, integral and integro-differential equations. An extension of the Tau method has been done for

The Novel Numerical Solutions for Time‐Fractional Fishers Equation

open access: yesAdvances in Mathematical Physics, Volume 2026, Issue 1, 2026.
A new method for solving time‐fractional partial differential equations (TFPDEs) is proposed in the paper. It is known as the fractional Kamal transform decomposition method (FKTDM). TFPDEs are approximated using the FKTDM. The FKTDM is particularly effective for solving various types of fractional partial differential equations (FPDEs), including time‐
