When assuming highly randomizing transmission, but incomplete measurement of input and output channels, the transmission matrix is often modelled as a random matrix with complex Gaussian elements.

Now let’s turn to closed-loop control. A closed-loop control system gathers feedback information from sensors and makes appropriate process adjustments at its output, automatically and without human ...

Earlier work (Sonis and Hewings, 1993, 1995; Sonis, Hewings and Miyazawa 1997a) has explored new ways of examining the structure of regional economies using input-output and social accounting systems.
