Vibrations of dam–plate of a hydro-technical structure under seismic load [PDF]
E3S Web of Conferences, 2021 In present paper, the problem of the vibration of a viscoelastic dam-plate of a hydro-technical structure is investigated, based on the Kirchhoff-Love hypothesis in the geometrically nonlinear statement.

Electronic Journal of Qualitative Theory of Differential Equations, 2009 We consider the Cauchy problem on the positive half-line for the differential-delay equation $$ \ddot u(t)+2c_0(t)\dot u(t)+c_1(t)\dot u(t-h)+d_0(t)u(t)+d_1(t)u(t-h)+d_2(t)u(t-2h)=0 $$ where $c_k(t), d_j(t) (t\geq 0; k=0,1; j=0,1,2)$ are continuous ...

Partial Differential Equations in Applied Mathematics, 2023 Many applications and natural phenomena in the fields of physics and engineering are described by ordinary and partial differential equations. Therefore, obtaining solutions to these equations helps to analyze and understand the dynamics of these systems,

On a nonlinear impulsive system of integro-differential equations with degenerate kernel and maxima
Nanosystems: Physics, Chemistry, Mathematics, 2022 A nonlocal boundary value problem for a system of ordinary integro-differential equations with impulsive effects, degenerate kernel and maxima is investigated. The boundary value problem is given by the integral condition.

A method for solving nonlinear Volterra’s population growth model of noninteger order
Advances in Difference Equations, 2017 Many numerical methods have been developed for nonlinear fractional integro-differential Volterra’s population model (FVPG). In these methods, to approximate a function on a particular interval, only a restricted number of points have been employed.

Distributed Control and the Lyapunov Characteristic Exponents in the Model of Infectious Diseases
Complexity, 2019 The Marchuk model of infectious diseases is considered. Distributed control to make convergence to stationary point faster is proposed. Medically, this means that treatment time can be essentially reduced.

A Certain Approximate Solutions of Nonlinear Flutter Equation
Engineering Transactions, 2015 A nonlinear integro-differential flutter equation of a thin airfoil placed in an incompressible flow is solved by two different methods. The first method involves the center-manifold reduction and gives the asymptotic limit cycle amplitude and frequency ...

Optimal dividends for a NatCat insurer in the presence of a climate tipping point
Canadian Journal of Statistics, EarlyView.Abstract We study optimal dividend strategies for an insurance company facing natural catastrophe claims, anticipating the arrival of a climate tipping point after which the claim intensity and/or the claim size distribution of the underlying risks deteriorates irreversibly.
