On the One-Leg Methods for Solving Nonlinear Neutral Differential Equations with Variable Delay [PDF]

open access: yesJournal of Applied Mathematics, 2012
Based on A-stable one-leg methods and linear interpolations, we introduce four algorithms for solving neutral differential equations with variable delay. A natural question is which algorithm is better.

Convergence of One-Leg Hybrid Methods for Implicit Mixed Differential Algebraic Systems [PDF]

open access: yesAbstract and Applied Analysis, 2015
This paper focuses on a hybrid multistep and its twin one-leg methods and implementing them on implicit mixed differential algebraic equations. The orders of convergence for the above methods are discussed and numerical tests are solved.

Stability analysis of one-leg methods for nonlinear functional differential and functional equations

open access: yesJournal of Computational and Applied Mathematics, 2010
The aim of this paper is to deal with the numerical methods for a nonlinear system \[ \begin{aligned} y'(t) & = f(t,y(t), y(t-\tau), z(t-\tau))\\ z'(t) & = g(t,y(t), y(t-\tau), z(t-\tau)), t\geq 0 \end{aligned} \] The adaptation of one-leg method is considered for solving systems of nonlinear functional differential and functional equations.

The effects of leg preference and leg dominance on static and dynamic balance performance in highly-trained tennis players.

open access: yesPLoS ONE, 2021
In this study, 90 (51 males, 39 females) tennis players performed single-leg quiet stance and single-leg landing tasks. For the static standing task, center-of pressure (CoP) velocities, amplitudes, frequency and area were calculated.

A simple anthropometric estimation formula for healthy female labourers’ leg volume

open access: yesAnnals of Human Biology, 2023
Background Leg volume (LV) is an important reference in nutrition, physiology in exercise, or clinical diagnosis. Therefore, how to evaluate LV easily and quickly with accuracy is important in these areas.
