Calculation of pipeline branches with considering nonlinearity of elastic base [PDF]

E3S Web of Conferences, 2023
When calculating systems on an elastic foundation, the generalized Reissner-Vlasov-Filomenko-Borodich model is traditionally used. Such models are acceptable for small displacements. For large displacements, there are some deviations from reality.

Existence and Stability of Periodic Solutions for Reaction-Diffusion Equations in the Two-Dimensional Case

Моделирование и анализ информационных систем, 2016
Parabolic singularly perturbed problems have been actively studied in recent years in connection with a large number of practical applications: chemical kinetics, synergetics, astrophysics, biology, and so on. In this work a singularly perturbed periodic

Stability of CW Solutions of the FDML Laser

Моделирование и анализ информационных систем, 2014
The problem of existense and stability of continuous wave (CW) solutions R exp(iΛt) of a Fourier Domain Mode Locking laser model is studied. This model consists of two differential equations with delay. The delay is sufficiently large.
