✦ Synopsis

The problem of matching modal vectors that stem from two different sources is addressed. While the traditional solution is to maximise the trace of a certain matrix of MAC (modal assurance criterion)-numbers, an improvement by which the full matrix is taken into account is suggested. The proposed method does not invoke any lengthy calculation and embraces the conventional approach as a special case. An industrial finite element model updating application is used to illustrate the performances of the traditional and modified strategies.

## Abstract We consider a boundary problem for an elliptic system in a bounded region Ω ⊂ ℝ^__n__^ and where the spectral parameter is multiplied by a discontinuous weight function __ω__ (__x__) = diag(__ω__~1~(__x__), …, __ω~N~__ (__x__)). The problem is considered under limited smoothness assump

## Abstract There are several reasons for investigating the inverse scattering problem in medical image processing. A typical case, that of ultrasonic fields, is considered. Assuming that a plane wave illuminates a weakly inhomogeneous two‐dimensional object, the fundamental equation is derived for

This paper is inspired by recent work of G.A.

We review Barnard's work, and generalize his family of priors in a mann

## Abstract The coronal loop problem is characterized by mixed boundary conditions and the loop length condition, which is global. Using singular perturbation methods one can identify and construct two boundary layers at the base of the loop. Extending this to a combined asymptotic‐numerical treat

## Abstract Both practical and conceptual problems arise in standard theories of multicomponent diffusion. They include the sometimes arbitrary and even artificial selection of one component as the solvent, the lack of explicit dependence on the properties of the solvent, and the difficulty in form
