A Comparative Study of One‐Step and Multi‐Step Numerical Methods for Solving Ordinary Differential Equations in Water Tank Drainage Systems

Engineering Reports, Volume 7, Issue 3, March 2025.
This study compares one‐step and multi‐step numerical methods for draining a water tank, assessing accuracy, stability, computational time, and memory. Multi‐step methods offer greater efficiency but require careful initialization and are more memory‐intensive.

Fractal-Fractional-Order Modeling of Liver Fibrosis Disease and Its Mathematical Results with Subinterval Transitions

Fractal and Fractional
In this paper, we study human liver disease with a different approach of interval-based investigation by introducing subintervals. This investigation may be referred to as a short memory investigation.

Characterizing the Central Structure of a Mesoscale Eddy‐Ring Dipole in the Mozambique Channel From In Situ Observations

Journal of Geophysical Research: Oceans, Volume 130, Issue 3, March 2025.
Abstract During the RESILIENCE cruise aboard the R/V Marion Dufresne II (April 19–24 May 2022), a high‐resolution in situ observation campaign investigated a mesoscale dipole in the Mozambique Channel, composed of a large anticyclonic ring and a cyclonic eddy.

N ordsieck form of multirate integration method for flexible multibody dynamic analysis

Computer Assisted Methods in Engineering and Science, 2023
A Nordsieck form of multirate integration scheme has been proposed for flexible multibody dynamic systems of which motions are represented by large gross motion coupled with small vibration.

The Benefits of Hierarchical Ecosystem Models: Demonstration Using EcoState, a New State‐Space Mass‐Balance Model

Fish and Fisheries, Volume 26, Issue 2, Page 203-218, March 2025.
ABSTRACT Ecosystem models predict changes in productivity and status for multiple species, and are important for incorporating climate‐linked dynamics in ecosystem‐based fisheries management. However, fishery regulations are primarily informed by single‐species stock assessment models, which estimate unexplained variation in dynamics (e.g., recruitment,

Scalar Auxiliary Variable (SAV) Stabilization of Implicit‐Explicit (IMEX) Time Integration Schemes for Non‐Linear Structural Dynamics

International Journal for Numerical Methods in Engineering, Volume 126, Issue 2, 30 January 2025.
ABSTRACT Implicit‐explicit (IMEX) time integration schemes are well suited for non‐linear structural dynamics because of their low computational cost and high accuracy. However, the stability of IMEX schemes cannot be guaranteed for general non‐linear problems.

Block Milne’s Implementation For Solving Fourth Order Ordinary Differential Equations [PDF]

, 2018
Block predictor-corrector method for solving non-stiff ordinary differential equations (ODEs) started with Milne’s device. Milne’s device is an extension of the block predictor corrector method providing further benefits and better results.
