    Analysis of helium bubble growth in radioactive waste
    (Nonlinear Analysis: Real World Applications, 2010) Carpio Rodríguez, Ana María; Tapiador Fernández, Bárbara
    A discrete kinetic model for the growth of helium bubbles in plutonium is proposed and analyzed. This model captures some relevant qualitative features of the time behavior of the distribution of bubble sizes. Analytic formulae for the solutions are given, which agree reasonably well with the numerical solutions, and a rigorous existence theory is established for three different equivalent formulations.

    Nonreflecting boundary conditions for discrete waves
    (Journal of Computational Physics, 2010) Tapiador Fernández, Bárbara; Carpio Rodríguez, Ana María
    We introduce a new class of nonreflecting boundary conditions for lattice models, which minimizes reflections at artificial boundaries. Exact integrodifferential boundary conditions for finite chains and half-spaces are obtained by means of Green's functions for initial value problems. Truncating the resulting integrals in time, we obtain absorbing boundary conditions. Numerical tests illustrate the ability of these conditions to suppress reflections.
