The formulation is based on the indi rect variational boundary element method (IVBEM). The quiver of the cum is computed from off functions de®ned between the ®eld points, where the acoustic push of the accredited ®eld is appointed, and the surface of the source. The IVBEM is employed for deriving the withdraw functions.

The capability to account for the presence of obstacles in the ®eld attached to the vibrating sources is include in the source reconstruction process. Treatment of arcsecond frequencies is include in the IVBEM formulation employed in this work and the reconstruction of the source can be achieved for all irradiation conditions. A sin gular value decomposition (SVD) solver is m! erged with the IVBEM computations in order to evaluate the vibration of the source from the transfer functions and the acoustic ®eld data. An algorithm that identi®es the optimum ®eld points where the acoustic pressure of the original ®eld must be prescribed in order to accomplish the most ef®cient source reconstruction is also developed. The optimum ®eld points are...If you want to rush a full essay, order it on our website: OrderCustomPaper.com
