✦ Synopsis

A new direct BE formulation is proposed for the solution of elastodynamic problems. An analytical regularization procedure is devised via an integration-by-parts technique without introducing any hypothesis about either the discretization of the boundary geometry or the space-time interpolation of the elastic ΓΏelds involved. The only requirement is for continuity in the displacement ΓΏeld. The regularization of the integral equations for static elasticity using the same approach, already available in the literature, is presented as a particular case of the general procedure introduced herein. The numerical implementation of this technique is discussed and two-dimensional examples are presented.

In many cases, monitoring data for ambient airborne particles can be organized in the form of a threeway data table with one way for chemical species, one for sampling periods and one for sites. A direct trilinear decomposition followed by a matrix reconstruction (DTDMR) is developed to analyze such
