A new Savage-Hutter type model for submarine avalanches and generated tsunami
(Elsevier, 2008)
In this paper we present a new two-layer model of Savage-Hutter type to study submarine avalanches. A layer composed of fluidized granular material is assumed to flow within an upper layer composed of an inviscid fluid (e. ...

Renormalized Solutions to a Nonlinear Parabolic-Elliptic System
(SIAM: Society for Industrial and Applied Mathematics, 2005)
The aim of this paper is to show the existence of renormalized solutions to a parabolicelliptic system with unbounded diffusion coefficients. This system may be regarded as a modified version of the well-known thermistor ...

L1-spaces of vector measures defined on δ-rings
(Springer, 2005)
Given a vector measure ν defined on a δ-ring with values in a Banach space, we study the relation between the analytic properties of the measure ν and the lattice properties of the space L1(ν) of real functions which are ...

Positive Representations of L1 of a Vector Measure
(Springer, 2007)
We characterize the vector measures n on a Banach lattice such that the map |·|dn provides a quasi-norm which is equivalent to the canonical norm · n of the space L1(n) of integrable functions as an specific type ...

On a matrix function interpolating between determinant and permanent
(Elsevier, 2005)
A matrix function, depending on a parameter t, and interpolating between the determinant and the permanent, is introduced. It is shown this function admits a simple expansion in terms of determinants and permanents of ...

On the cohomology of 3D digital images
(2005)
We propose a method for computing the cohomology ring of three-dimensional (3D) digital binary-valued pictures. We obtain the cohomology ring of a 3D digital binary-valued picture I , via a simplicial complex K(I)K(I) ...

The thermistor problem with degenerate thermal conductivity and metallic conduction
(American Institute of Mathematical Sciences, 2007)
The aim of this work is to establish the existence of a capacity solution to the thermistor problem supposing that the thermal and the electrical conductivities are not bounded below by a positive constant value. ...

Maximizing Trip Coverage in the Location of a Single Rapid Transit Alignment
(Springer, 2005)
This article describes several heuristics for the construction of a rapid transit alignment. The objective is the maximization of the total origin-destination demand covered by the alignment. Computational results show ...

Explicit Comparison Theorems for D -modules
(Elsevier, 2001)
We prove in an explicit way a duality formula between two A2-modules Mlog and Mflog associated to a plane curve and we give an application of this duality to the comparison between Mflog and the A2-module of rational ...

Absolute continuity theorems for abstract Riemann integration
(Springer, 2007)
Absolute continuity for functionals is studied in the context of proper and abstract Riemann integration examining the relation to absolute continuity for finitely ad ditive measures and giving results in both directions: ...
