Nielsen Ratings
Nielsen Media Research (NMR) is an American firm that measures media audiences, including television, radio, theatre, films (via the AMC Theatres MAP program), and newspapers. Headquartered in New York City, it is best known for the Nielsen ratings, an audience measurement system of television viewership that for years has been the deciding factor in canceling or renewing television shows by television networks. As of May 2012, it is part of Nielsen Holdings. NMR began as a division of ACNielsen, a 1923-founded marketing research firm. In 1996, NMR was split off into an independent company, and in 1999, was purchased by the Dutch conglomerate VNU. In 2001, VNU also purchased ACNielsen, thereby bringing both companies under the same corporate umbrella. NMR is also a sister company to Nielsen//NetRatings, which measures Internet and digital media audiences. VNU was reorganized and renamed the Nielsen Company in 2007.

Nielsen Park She-Oak
''Allocasuarina portuensis'', commonly known as the Nielsen Park she-oak, is an extremely rare plant growing in Sydney, Australia. Encountered as a shrub or small slender tree, up to tall, it has green drooping branchlets up to in length. It is dioecious, that is, male and female flowers are borne on separate plants. Measuring long and 0.8–1 cm wide, the cones are perched on 0.2–1.5 cm long peduncles arising from the branchlets. The plant was discovered by Peter Brookhouse, a NPWS Ranger who worked at Sydney Harbour National Park. It was officially described by Lawrie Johnson in 1989. The specific epithet ''portuensis'' is from the Latin, meaning "inhabiting a port", as this species was originally found at Port Jackson.Les Robinson - Field Guide to the Native Plants of Sydney, p. 151 It most resembles '' Allocasuarina rigida'' and '' A. distyla'' and can be distinguished by differences in the male flowers. ''A. portuensis'' was originally identified in 1986 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nielsen Gallery
Nielsen Gallery is a commercial art gallery originally located on Newbury Street in the Back Bay area of Boston, United States. Founded in 1963 by Nina Nielsen and John Baker, the gallery won “Best Show in a Commercial Gallery in the United States,” prizes from the International Association of Art Critics, in 2005 and 2009. Originally a frame shop that also sold Japanese prints, they began to exhibit paintings in 1973. During the 46 years that the gallery was open in its original building, and also in its current online and by-appointment incarnation, it has showcased and supported contemporary American artists, especially those creating experimental and avant-garde work. The gallery's spirit was described by ''Artdeal Magazine'' as "the warmest, most intense, most powerful and inspirational art experience north of Manhattan.” Artists featured through the gallery have included Jackson Pollock, Joan Snyder, Dexter Lazenby, Nathalie Miebach, James Cambronne, Albert York, Arthur ...

Nielsen Fixed-point Theorem
Nielsen theory is a branch of mathematical research with its origins in topological fixed-point theory. Its central ideas were developed by Danish mathematician Jakob Nielsen, and bear his name. The theory developed in the study of the so-called ''minimal number'' of a map ''f'' from a compact space to itself, denoted ''MF'' 'f'' This is defined as: :\mathit = \min \, where ''~'' indicates homotopy of mappings, and #Fix(''g'') indicates the number of fixed points of ''g''. The minimal number was very difficult to compute in Nielsen's time, and remains so today. Nielsen's approach is to group the fixed-point set into classes, which are judged "essential" or "nonessential" according to whether or not they can be "removed" by a homotopy. Nielsen's original formulation is equivalent to the following: We define an equivalence relation In mathematics, an equivalence relation is a binary relation that is reflexive, symmetric and transitive. The equipollence relation between line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nielsen (crater)
Nielsen is a lunar impact crater on the Oceanus Procellarum. It is located north-east of Montes Agricola on the western hemisphere of the Moon. To the east-southeast is the crater Wollaston. Nielsen is a bowl-shaped formation that lies astride a small ridge that runs north-northwestwards towards the Mons Rümker. The latter is an unusual raised formation of lunar dome A lunar dome is a type of shield volcano that is found on the surface of the Earth's Moon. They are typically formed by highly viscous, possibly silica-rich lava, erupting from localized vents followed by relatively slow cooling. Lunar domes are ...s.

Nielsen–Olesen Vortex
In theoretical physics, a Nielsen–Olesen vortex is a point-like object localized in two spatial dimensions or, equivalently, a classical solution of field theory with the same property. This particular solution occurs if the configuration space of scalar fields contains non-contractible circles. A circle surrounding the vortex at infinity may be "wrapped" once on the other circle in the configuration space. A configuration with this non-trivial topological property is called the Nielsen–Olesen vortex, after Holger Bech Nielsen and Poul Olesen (1973). The solution is formally identical to the solution of Quantum vortex in superconductor. See also * Nielsen–Olsen string * Abrikosov vortex *Montonen–Olive duality *S-duality In theoretical physics, S-duality (short for strong–weak duality, or Sen duality) is an equivalence of two physical theories, which may be either quantum field theories or string theories.
