A Hybrid Fitted Mesh Numerical Scheme for Solving Singularly Perturbed Reaction–Diffusion Equation With Mixed Shifts

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
This study develops a robust hybrid numerical scheme for a class of time‐dependent, singularly perturbed differential‐difference equations characterized by a small positive parameter multiplying the highest order derivative term and mixed spatial shifts (delay and advance) in the reaction terms.

Oscillations of Numerical Solutions for Nonlinear Delay Differential Equations in the Control of Erythropoiesis

open access: yesDiscrete Dynamics in Nature and Society, 2013
We consider the oscillations of numerical solutions for the nonlinear delay differential equations in the control of erythropoiesis. The exponential θ-method is constructed and some conditions under which the numerical solutions oscillate are presented ...

Nonoscillatory solutions for first-order neutral dynamic equations with continuously distributed delay on time scales

open access: yesAdvances in Difference Equations, 2019
In this paper, we establish the existence of nonoscillatory solutions to the neutral dynamic equation [x(t)−∫abp(t,η)x(g(t,η))Δη]Δ+∫cdω(t,ν)x(h(t,ν))Δν=0 $$\biggl[x(t)- \int_{a}^{b}p(t,\eta)x\bigl(g(t,\eta)\bigr)\Delta \eta \biggr]^{\Delta }+ \int_{c}^{d}

Exact Solitary Wave Solutions in Nonlinear Carbon Nanotube Composite Beams on Viscoelastic Foundations Under M‐Truncated Derivative

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
In this study, the nonlinear partial differential equation that governs the free vibration of a carbon nanotube composite beam is analytically investigated using the truncated M‐fractional derivative. This model is a beam supported by a nonlinear viscoelastic base and reinforced by carbon nanotubes.

Manipulator Control Using CSRT Algorithm in Image‐Based Visual Servoing Technique and ROS 2 Tools

open access: yesJournal of Robotics, Volume 2026, Issue 1, 2026.
Achieving precise robotic manipulation is difficult when objects are unknown or not pretrained, and the environment is unpredictable. Traditional cameras often struggle with depth perception and lag when a robot gets close to its target. To address these limitations, this study explores the design and implementation of an image‐based visual servoing ...

Dynamics of Downdrafts Around a Growing Convective Cloud: A Numerical Study

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 22, 28 November 2025.
Abstract We examine the dynamics of cloud‐edge downdrafts over the growth phase of isolated cumuli, combining Eulerian and Lagrangian analyses. As in previous studies, our results show that growing cumuli are surrounded by downdrafts linked to cloud‐scale quasi‐toroidal circulations at all times at middle and upper cloud levels consistent with the ...

Asymptotic properties of nonoscillatory solutions of higher order neutral difference equations [PDF]

open access: yesOpuscula Mathematica, 2006
In this paper we study asymptotic behavior of solutions of a higher order neutral difference equation of the form \[\Delta^m(x_n+p_nx_{n-\tau})+f(n,x_{\sigma (n)})=h_n.\] We present conditions under which all nonoscillatory solutions of the above ...

Necessary and sufficient conditions for oscillation of the solutions of even order differential equations

open access: yesJournal of Numerical Analysis and Approximation Theory, 2012
In this paper, we establish several necessary and sufficient conditions for oscillation of the solutions of the following even order differential equation\[x^{(n)}(t) + q(t)x^\gamma (t) = 0, \quad \mbox{$n$ is even},\]where \( q(t) \in C([t_0 ,\infty ),{\
