Waste recovery a way reduce production process by using system generate with no more fuel or consumption. In typical plant, 25% energy, 75% ...

An image on the retina of a human eye enters the visual system through an array of photoreceptors that sets the boundaries on the spatial detail available for neural representation. In order to investigate the extent to which the input spatial detail is preserved by the human neural system, we compare the anatomical spatial limits as determined by the Nyquist frequency, the highest spatial freq...
