The tape head interaction in magnetic recording is modelled by a coupled system of a second order differential equation for the pressure and a fourth-order differential equation for the tape deflection. There is also the constraint that the spac[...]texto impreso
In this paper we study a non-linear system of differential equations arising in chemotaxis. The system consists of a PDE that describes the evolution of a population and an ODE which models the concentration of a chemical substance. We study the[...]texto impreso
Díaz Díaz, Jesús Ildefonso ; Bermejo, R. ; Carpio, Jaime ; Tello, J. Ignacio | Pergamon-Elsevier Science Ltd | 2009-03The purpose of this paper is to carry out the mathematical and numerical analysis of a two-dimensional nonlinear parabolic problem on a compact Riemannian manifold without boundary, which arises in the energy balance for the averaged surface tem[...]texto impreso
We study the limit case corresponding to a model introduced by G.L. Stenchikov and A. Robock for the evolution of the temperature of an atmospheric column in absence of humidity. The model envolves a degenerate noncoercive quasilinear equation. [...]
