A Family of Higher‐Order Theories for Wave Propagation in One‐Dimensional Structural Elements
International Journal for Numerical Methods in Engineering, Volume 126, Issue 19, 15 October 2025.ABSTRACT This paper proposes a systematic framework for the development and classification of higher‐order theories for modeling wave propagation in one‐dimensional structural elements. Building upon and organizing the existing higher‐order models, a generalized approach is introduced to construct an entire family of such theories with controllable ...

Advanced Theory and Simulations, Volume 8, Issue 10, October 2025.This work proposes a surface elasticity‐based nonlocal model for analyzing the vibrations of bi‐directionally graded tapered nanobeam. The results demonstrate that, in absence of surface effect, the increasing value of tapered parameter leads to stiffness‐hardening of the nanobeam. However, the consideration of surface effect changes this trend and the

Iterative Optimal Control for Flexible Rotor–AMB System [PDF]
Acta Montanistica Slovaca, 2010 In this paper we propose an optimal control design technique for a class of nonlinear and control non-affine equations.The dynamic equations of a flexible shaft supported by a pair of active magnetic bearings (AMBs) are used as the nonlinear control ...

Local solutions for a Timoshenko system in noncylindrical domains
Portugaliae Mathematica, 2008 In this paper we study a Timoshenko system modeling transverse vibrations of thin elastic beams in a moving boundary domain. Existence and uniqueness of a local solution is proved by using Faedo–Galerkin approximation.

Chemistry–Methods, Volume 5, Issue 10, October 2025.The experimental setup presented in this work combining laboratory‐based X‐ray absorption spectroscopy with an electrochemical reactor advances the fundamental understanding of electrocatalysts at extended time scales. By the example of the electrochemical reduction of CO2, the parameters are discussed that are relevant for optimizing the system to ...

Decay rate of the Timoshenko system with one boundary damping
Evolution Equations and Control Theory, 2019 In this paper, we study the indirect boundary stabilization of the Timoshenko system with only one dissipation law. This system, which models the dynamics of a beam, is a hyperbolic system with two wave speeds. Assuming that the wave speeds are equal, we

International Journal for Numerical Methods in Biomedical Engineering, Volume 41, Issue 10, October 2025.Otherwise healthy individuals with transfemoral amputation, even young athletes and servicemen, are consistently diagnosed with low levels of bone mineral density in their residual limb. Our computational analysis examined the effect of a prosthetic socket on the mechanical stimulus in 10 subjects under three fittings during ground reaction forces of ...
