shock waves

Modeling and numerical simulation of shockwaves in porous materials

A postdoctoral position is available immediately in the Laboratory of Microstructure Studies and Mechanics of Materials (LEM3) of the University of Lorraine (UL) in Metz, France.

Abstracts for the 2011 APS Topical Conference on Shock Compression of Condensed Matter are now being accepted.  This biennial meeting is the premier conference for shock compression, behavior of materials at high pressures and high strain rates, and related areas.  We hope you will be able to join us for an outstanding Conference in Chicago, Illinois, June 26 - July 1, 2011.

Dear Sir，

As we know, periodic signals are best analysed in the frequency domain while stochastic signals are usually more profitably analysed in the time domain. The analysis in the frequency domain usually concern only one signal while in the time domain often involves the comparison of several different signals.

1) what are the general methods for transforming the frequency domain into time domain, and which should be superior?
