Re: underground communication using seismic waves

For a magnetic system, we would relate the transmitter's magnetic moment to the received magnetic field strength. What is the equivalent in seismic terms? Would it be to relate the pressure lev...

Re: PHP DIO module

Have you checked the process has permission to create that directory? Well, I wondered about that, but this is Windows we're talking about, so can permissions be an issue?

Have you considered GD Graphics which is already install?
