Fading is the variation in received signal strength due to changes in the physical characteristics of the propagation medium, which alter the interaction of multipath components of the transmitted signal. The principal means of counteracting fading are diversity methods, which are based on the exploitation of the latent redundancy in two or more ...

On the Fade Duration Distribution in Nakagami Fading Channels
2007 IEEE International Conference on Communications, 2007During almost fifty years the fade duration distribution (FDD) of random signals has been an open research topic. However, for Nakagami fading channels, and in general for the great majority of non-Gaussian processes, closed form general solutions are still unknown.

The fading of colouring matters
Journal of Applied Chemistry, 1964AbstractAn outline of the causes and nature of fading of organic colouring matters is given. Atmospheric fading, in absence of light, is produced by nitrogen oxides in urban air, especially with blue and violet disperse dyes on some hydrophobic fibres, but sulphur dioxide and ozone can also cause fading.

Two English women are described who developed chestnut-brown pigmentation of the distal part of the finger- and thumb-nail plates whilst using 'over the counter' topical hydroquinone depigmenting creams. In both individuals there was marked deepening of the pigmentation during periods of intense sun exposure.

A faded mountain at the edge of a threadbare field. Smoke and dust trudging the last rungs of a sky. And now a narrow dirt road that twists between snatches of shivering trees and snatches of shadow. Then a gasping river, and cattle and goats and children running across an empty yard, yelling into the wind.

Comparative Education Review, 1987
Tennyson's evocative sense of the future, though alluding to Homeric Greece, pertains to our technological age and more truly depicts the prospect of the majority of human beings on the eve of the twenty-first century than does any forecast or scenario wrought from technological optimism.

In 1884 Ivo Bruns began his Lucrez-Studien, on the relationship between Lucretius' treatment of Epicureanism and the exposition by the philosopher himself in the extant Epistles, with the question (p.4) for whom did Lucretius write? His answer was to show (p.l 1) that the general public, who were the poet's real objective, were very different readers ...
