Chicago Tribune
The ''Chicago Tribune'' is a daily newspaper based in Chicago, Illinois, United States, owned by Tribune Publishing. Founded in 1847, and formerly self-styled as the "World's Greatest Newspaper" (a slogan for which WGN radio and television are named), it remains the most-read daily newspaper in the Chicago metropolitan area and the Great Lakes region. It had the sixth-highest circulation for American newspapers in 2017. In the 1850s, under Joseph Medill, the ''Chicago Tribune'' became closely associated with the Illinois politician Abraham Lincoln, and the Republican Party's progressive wing. In the 20th century under Medill's grandson, Robert R. McCormick, it achieved a reputation as a crusading paper with a decidedly more American-conservative anti-New Deal outlook, and its writing reached other markets through family and corporate relationships at the ''New York Daily News'' and the ''Washington Times-Herald.'' The 1960s saw its corporate parent owner, Tribune Company, rea ...

White Gaussian Noise
In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density. The term is used, with this or similar meanings, in many scientific and technical disciplines, including physics, acoustical engineering, telecommunications, and statistical forecasting. White noise refers to a statistical model for signals and signal sources, rather than to any specific signal. White noise draws its name from white light, although light that appears white generally does not have a flat power spectral density over the visible band. In discrete time, white noise is a discrete signal whose samples are regarded as a sequence of serially uncorrelated random variables with zero mean and finite variance; a single realization of white noise is a random shock. Depending on the context, one may also require that the samples be independent and have identical probability distribution (in other words independent and identica ...

Additive White Gaussian Noise
Additive white Gaussian noise (AWGN) is a basic noise model used in information theory to mimic the effect of many random processes that occur in nature. The modifiers denote specific characteristics: * ''Additive'' because it is added to any noise that might be intrinsic to the information system. * ''White'' refers to the idea that it has uniform power across the frequency band for the information system. It is an analogy to the color white which has uniform emissions at all frequencies in the visible spectrum. * ''Gaussian'' because it has a normal distribution in the time domain with an average time domain value of zero. Wideband noise comes from many natural noise sources, such as the thermal vibrations of atoms in conductors (referred to as thermal noise or Johnson–Nyquist noise), shot noise, black-body radiation from the earth and other warm objects, and from celestial sources such as the Sun. The central limit theorem of probability theory indicates that the summation ...

WGN, Journal Of The International Meteor Organization
The International Meteor Organization (IMO) was formally founded in 1988 from predecessor gatherings over many years. IMO has several hundred members and was created in response to an ever-growing need for international cooperation on amateur and professional meteor work. The collection of meteor observations by several methods from all around the world ensures the comprehensive study of meteor showers and their relation to comets and interplanetary dust. IMO publishes a bimonthly journal called ''WGN''WGN = "werkgroepnieuws" (Dutch language), in English as "workgroup news". WGN was initially a circular before it became a journal. and holds an annual International Meteor Conference (IMC) in September.IMO website. See also *American Meteor Society *List of astronomical societies *Meteoritics Meteoritics is the science that deals with meteors, meteorites, and meteoroids. It is closely connected to cosmochemistry, mineralogy and geochemistry. A specialist who studies meteoritics i ...
