The Schumann resonance frequencies are a set of eigenmodes in the extremely low frequency (ELF) portion of the electromagnetic field spectrum. These frequencies are only present for planetary-like bodies with a substantial ionosphere acting as a perfect electric conductor, thus forming a resonance cavity with the surface. In this example, the Schumann resonance frequencies for the Earth are calculated.
Image enhancement in frequency domain using Fourier center frequency, Gaussian lowpass filter, Low pass filter, high pass filter. Image restoration using medean filter, weiner filter with noise generator such as Gaussian noise, Salt and Pepper noise
X-MAC, a low power MAC
protocol for wireless sensor networks (WSNs). Standard
MAC protocols developed for duty-cycled WSNs such as
BMAC, which is the default MAC protocol for TinyOS, employ
an extended preamble and preamble sampling.
