Lagrange interpolation processes based on the zeros of anti-Gauss Jacobi polynomials
Patricia Díaz de Alba, Luisa Fermo, Valerio Loi +1
This paper introduces and investigates a new Lagrange interpolation process based on the zeros of anti-Gauss Jacobi polynomials. Fundamental properties of anti-Gauss nodes, includi…
Anti-Gauss Lagrange interpolation: Christoffel-Darboux form, barycentric representation, and orthogonal expansion
Patricia Díaz de Alba, Luisa Fermo, Valerio Loi
The paper deals with new formulations of a Lagrange interpolant polynomial based on the nodes of the well-known anti-Gauss rule. A first representation is given in terms of the cla…
Anti-Gauss cubature rules with applications to Fredholm integral equations on the square
Patricia Diaz de Alba, Luisa Fermo, Giuseppe Rodriguez
The purpose of this paper is to develop the anti-Gauss cubature rule for approximating integrals defined on the square whose integrand function may have algebraic singularities at…
Forward electromagnetic induction modelling in a multilayered half-space: An open-source software tool
Gian Piero Deidda, Patricia Díaz de Alba, Federica Pes +1
Electromagnetic induction (EMI) techniques are widely used in geophysical surveying. Their success is mainly due to their easy and fast data acquisition, but the effectiveness of d…
Regularized minimal-norm solution of an overdetermined system of first kind integral equations
Patricia Díaz de Alba, Luisa Fermo, Federica Pes +1
Overdetermined systems of first kind integral equations appear in many applications. When the right-hand side is discretized, the resulting finite-data problem is ill-posed and adm…
FDEMtools: a MATLAB package for FDEM data inversion
Gian Piero Deidda, Patricia Díaz de Alba, Caterina Fenu +2
Electromagnetic induction surveys are among the most popular techniques for non-destructive investigation of soil properties in order to detect the presence of either ground inhomo…
