A numerical method with properties of consistency in the energy domain for a class of dissipative nonlinear wave equations with applications to a Dirichlet boundary-value problem
J. E. Macías-Díaz, A. Puri
In this work, we present a conditionally stable finite-difference scheme that consistently approximates the solution of a general class of (3+1)-dimensional nonlinear equations tha…
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 transmission of binary bits in discrete Josephson-junction arrays
J. E. Macías-Díaz, A. Puri
In this work, we use supratransmission and infratransmission in the mathematical modeling of the propagation of digital signals in weakly damped, discrete Josephson-junction arrays…
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
