The problem of acceleration in the dynamics of a double-link wheeled vehicle with arbitrarily directed periodic excitation [PDF]

open access: yesTheoretical and Applied Mechanics, 2023
This study investigates the motion of a nonholonomic mechanical system that consists of two wheeled carriages articulated by a rigid frame. There is a point mass which oscillates at a given angle 𝛼 to the main axis of one of the carriages.

Dynamics of full-coupled chains of a great number of oscillators with a large delay in couplings [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика, 2023
The subject of this work is the study of local dynamics of full-coupled chains of a great number of oscillators with a large delay in couplings. From a discrete model describing the dynamics of a great number of coupled oscillators, a transition has been

Asymptotic expansions for approximate solutions of boundary integral equations [PDF]

open access: green
This paper uses the Modified Projection Method to examine the errors in solving the boundary integral equation from Laplace equation. The analysis uses weighted norms, and parallel algorithms help solve the independent linear systems. By applying the method developed by Kulkarni, the study shows how the approximate solution behaves in polygonal domains.

Asymptotically periodic solutions to Volterra integral equations in epidemic models

open access: bronzeJournal of Mathematical Analysis and Applications, 1985
The author studies the equation \[ x(t)=f(t)+\int^{t}_{0}a(s)P(t- s)g(x(s))ds \] which arises in models for SIS epidemics and he proves some results saying that if either f or a are periodic functions, then the solution x is asymptotically periodic. These results are applied to several models used in describing epidemics of gonorrhea and some numerical

Asymptotics of Solutions of Some Integral Equations Connected with Differential Systems with a Singularity [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2020
Our studies concern some aspects of scattering theory of the singular differential systems y ′ − x −1Ay − q(x)y = ρBy, x 0 with n × n matrices A, B, q(x), x ∈ (0, ∞), where A, B are constant and ρ is a spectral parameter.

Uniform Approximation to the Solution of a Singularly Perturbed Boundary Value Problem with an Initial Jump

open access: yesMathematics, 2020
In this study, a third-order linear integro-differential equation with a small parameter at two higher derivatives was considered. An asymptotic expansion of the solution to the boundary value problem for the considered equation is constructed by ...

Asymptotic growth of the 4d N $$ \mathcal{N} $$ = 4 index and partially deconfined phases

open access: yesJournal of High Energy Physics, 2020
We study the Cardy-like asymptotics of the 4d N $$ \mathcal{N} $$ = 4 index and demonstrate the existence of partially deconfined phases where the asymptotic growth of the index is not as rapid as in the fully deconfined case.
