This paper is concerned with a new prediction methodology for longitudinally invariant soil-structure interaction problems in elastodynamics. The method uses the finite-element method to model the structure, the boundary-element ...

In this paper, a new prediction methodology to deal with longitudinally invariant soil-structure interaction problems in elastodynamics is presented. The method uses the finite-element method to model the structure, the ...

For the production of representative noise maps, a large amount of information is necessary, which includes, among others, on-site measurements of environmental noise. Thus, mobile sampling emerges as a possible solution ...

This article elaborates on an extension to the classical stiffness matrix method to obtain the Green's functions for two-and-a-half dimensional (2.5D) elastodynamic problems in homogeneous and horizontally layered half-spaces. ...

In this paper, a comprehensive numerical approach formulated in two-and-a-half dimension (2.5D) for modelling track/tunnel/soil systems in the context of ground-borne railway-induced vibration problems considering a ...

The reduction on sound transmission through an aperture by active means is theoretically investigated. The primary field is composed by a plane wave that arrives at a rectangular aperture placed in an infinite rigid thin ...

In many cities can be found areas where there is a high concentration of local leisure activities and evening entertainment (music bars, nightclubs, restaurants…) that develop their activity in coexistence with the residential ...

A passive acoustic method for aircraft localization is experimentally tested in this paper. The method relies on the Doppler effect influencing the signals received by a mesh of microphones distributed over the acoustic ...

The present paper presents a passive acoustic method for aircraft tracking. The Acoustical Doppler Effect, characteristic of signals received by a mesh of spatially distributed microphones is the basis of the method. A ...
