A Client’s Guide To Site Investigation Introduction Why Carry Out a Site Investigation? The objective of this brief guide is to inform promoters of civil engineering and building projects of the importance of adequate site investigation for the successful completion of their project. It indicates what a site investigation is likely to comprise‚ the important role of the promoter‚ and the risk to the project of undertaking an inappropriate or inadequate site investigation.

Ave‚ Cambridge‚ MA 02139 We have developed MATLAB software and a Simulink subsystem block which work in tandem to extract the transfer function (amplitude and phase) of a system using ‘swept sine’ excitation. The resulting dynamic signal analyzer provides a convenient tool for obtaining empirical Bode plots of system and controller dynamics within the dSPACE environment.

process of phase conjugation in the frequency domain‚4–8 focuses sound from a source–receive array ~SRA! back to the probe source ~PS! which ensonified the SRA. The SRA receives the probe-source field‚ time reverses it ~phase conjugation in the frequency domain!‚ and then uses the time-reversed data as the excitation for an array of sources which are collocated with the receiving hydrophones. If the ocean environment does not change significantly during the two-way travel time‚ the phase-conjugate
