This paper presents a generalization of Kokaram's model for scratch lines detection on digital film materials. It is based on the assumption that scratch is not purely additive on a given image but shows also a destroying effect. This result allows us to design a more efficacious scratch detector… |

The gravitational-wave signal from inspiralling neutron-star--neutron-star
(or black-hole--neutron-star) binaries will be influenced by tidal coupling
in the system. An important science goal in the gravitational-wave detection
of these systems is to obtain information about the equation of… |

Many scientific applications require the solution of large and sparse linear systems of equations using Krylov subspace methods; in this case, the choice of an effective preconditioner may be crucial for the convergence of the Krylov solver. Algebraic MultiGrid (AMG) methods are widely used as… |

We study the L^2 stability of a classical solution of the one-dimensional energy transport model for semiconductors on the whole rel line, under the assumption that the thermodynamic variables remain bounded. The solution converges asymptotically in time to a state in thermodynamic equilibrium. |

Previous numerical studies have shown that the 'ultimate regime of thermal convection' can be attained in a Rayleigh-Bénard cell when the kinetic and thermal boundary layers are eliminated by replacing both lateral and horizontal walls with periodic boundary conditions (homogeneous Rayleigh-Bénard… |

Computer simulations of bi-continuous two-phase fluids with interspersed dumbbells show that, unlike rigid colloids, soft dumbbells do not lead to arrested coarsening. However, they significantly alter the curvature dynamics of the fluid-fluid interface, whose probability density distributions are… |

In recent years a number of variational models related to reconstruction problems in computer vision have been proposed. |

The energy content of cylindrical gravitational wave spacetimes is analyzed by considering two local descriptions of energy associated with the gravitational field, namely those based on the C-energy and the Bel-Robinson super-energy tensor. A Poynting-Robertson-like effect on the motion of massive… |
