Fractional Timoshenko beam with a viscoelastically damped rotational component
AIMS Mathematics, 2023 This paper is concerned with a fractional Timoshenko system of order between one and two. We address the question of well-posedness in an appropriate space when the rotational component is viscoelastic or subject to a viscoelastic controller. To this end

Flexoelectric Effects of Nanoscale Electrical Materials Under Dynamic Conditions
Energy Science &Engineering, EarlyView.ABSTRACT Material flexoelectricity is due to strain gradients at the material's small dimensions, and nanoelectronics more precisely enhances the heightened sensitivity at this reduced scale. Below, the study presents a sensitivity analysis in active applications, such as sensors and actuators, to these effects, focusing on how flexoelectricity ...

Vibrations of a Timoshenko beam on an inertial foundation under a moving load
MATEC Web of Conferences, 2018 In the paper vibrations of the Timoshenko beam on an inertial foundation subjected to a moving force are discussed. Considered model of the inertial foundation is described by three parameters.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT The supercritical drive shaft is becoming increasingly popular in helicopter transmission system. Dry friction dampers are specially employed to ensure the supercritical shafts crossing the critical speed safely. Due to design tolerances, manufacturing errors and time‐varying factors, the parameters of the damper are inherently uncertain ...

Uniform controllability for Kirchhoff and Mindlin-Timoshenko elastic systems
Electronic Journal of Differential Equations, 1999 The Mindlin-Timoshenko operator is a perturbation of the Kirchhoff operator and it is well known that there exist solutions to the exact controllability problem for their associated systems.

Riesz basis property of Timoshenko beams with boundary feedback control
International Journal of Mathematics and Mathematical Sciences, 2003 A Timoshenko beam equation with boundary feedback control is considered. By an abstract result on the Riesz basis generation for the discrete operators in the Hilbert spaces, we show that the closed-loop system is a Riesz system, that is, the sequence of

Drivers of human attitudes towards wolves Canis lupus in Kazakhstan
People and Nature, EarlyView.Abstract Kazakhstan is recognized as a key stronghold for the grey wolf (Canis lupus). Nonetheless, the wolf status and the dynamics of human‐wolf coexistence in the region remain poorly understood. This study aims to fill that gap by exploring current attitudes towards wolves in Kazakhstan and identify the underlying drivers of these attitudes.
