A numerical method for computing radially symmetric solutions of a dissipative nonlinear modified Klein-Gordon equation
J. E. Macías-Díaz, A. Puri
In this paper we develop a finite-difference scheme to approximate radially symmetric solutions of the initial-value problem with smooth initial conditions in an open sphere around…
On the propagation of binary signals in damped mechanical systems of oscillators
J. E. Macías-Díaz, A. Puri
In the present work, we explore efficient ways to transmit binary information in discrete, semi-infinite chains of coupled oscillators using the process of nonlinear supratransmiss…
An application of nonlinear supratransmission to the propagation of binary signals in weakly damped, mechanical systems of coupled oscillators
J. E. Macías-Díaz, A. Puri
In the present article, we simulate the propagation of binary signals in semi-infinite, mechanical chains of coupled oscillators harmonically driven at the end, by making use of th…
An energy-based computational method in the analysis of the transmission of energy in a chain of coupled oscillators
J. E. Macías-Díaz, A. Puri
In this paper we study the phenomenon of nonlinear supratransmission in a semi-infinite discrete chain of coupled oscillators described by modified sine-Gordon equations with const…
