Rotations of a Rigid Body Close to the Lagrange Case under the Action of Nonstationary Perturbation Torque [PDF]
Journal of Applied and Computational Mechanics, 2022 Perturbed motions of a rigid body, close to the Lagrange case, under the action of restoring and perturbation torques of forces are investigated in the paper. The following problem is formulated: investigating solutions behavior of system of equations of

Mathematical Modelling and Analysis, 2016 We consider averaging methods for solving the 3-D boundary-value problem of second order in multilayer domain. The special hyperbolic and exponential type splines, with middle integral values of piece-wise smooth function interpolation are considered ...

Commutator method for averaging lemmas
Analysis & PDE, 2022 We introduce a commutator method with multipliers to prove averaging lemmas, the regularizing effect for the velocity average of solutions for kinetic equations. This method requires only elementary techniques in Fourier analysis and shows a new range of assumptions that are sufficient for the velocity average to be in $L^2([0,T],H^{1/2}_x).$ This ...

Моделирование и анализ информационных систем, 2014 In this paper we study the asymptotic integration problem in the neighborhood of infinity for a certain class of linear functional differential systems. We construct the asymptotics for the solutions of the considered systems in a critical case.

Averaging Methods for Second-Order Differential Equations and Their Application for Impact Systems
Mathematics, 2020 In this paper, we discuss the averaging method for periodic systems of second order and the behavior of solutions that intersect a hyperplane. We prove an averaging theorem for impact systems.

Oscillation Control Algorithms for Resonant Sensors with Applications to Vibratory Gyroscopes
Sensors, 2009 We present two oscillation control algorithms for resonant sensors such as vibratory gyroscopes. One control algorithm tracks the resonant frequency of the resonator and the other algorithm tunes it to the specified resonant frequency by altering the ...
