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…

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…

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…
