The present invention applies computer techniques to the power spectrum analysis of brain wave signals, wherein the power spectrum fluctuations of supra-slow wave is obtained by selecting the maximum value of the power amplitude within 0. In one embodiment, a method involves transmitting a primary data transmission over a computer network from a source host to a receiving host. When the semiconductor material is annealed, the second dopant becomes mobile and moves through the lattice so as to promote atomic disorder.
