An atlas is a collection of maps; it is typically a map of Earth or a region of Earth, but there are atlases of the other planets (and their satellites) in the Solar System. Furthermore, atlases of anatomy exist, mapping out the human body or other organisms. Atlases have traditionally been bound into book form, but today many atlases are in multimedia formats. In addition to presenting geographic features and political boundaries, many atlases often feature geopolitical, social, religious and economic statistics. They also have information about the map and places in it.
The word atlas dates from 1636, first in reference to the English translation of Atlas, sive cosmographicae meditationes de fabrica mundi (1585) by Flemish geographer Gerhardus Mercator, who might have been the first to use this word in this way. A picture of the Titan Atlas holding up the world appeared on the frontispiece of this and other early map collections.
The first work that contained systematically arranged woodcut maps of uniform size, intended to be published in a book, thus representing the first modern atlas, was De Summa totius Orbis (1524–26) by the 16th-century Italian cartographer Pietro Coppo. Nonetheless, this distinction is conventionally awarded to the Flemish cartographer Abraham Ortelius who in 1570 published the collection of maps Theatrum Orbis Terrarum.
The Atlas Computer was a joint development between the University of Manchester, Ferranti, and Plessey. The first Atlas, installed at Manchester University and officially commissioned in 1962, was one of the world's first supercomputers, considered to be the most powerful computer in the world at that time. It was said that whenever Atlas went offline half of the United Kingdom's computer capacity was lost. It was a second-generation machine, using discrete germanium transistors. Two other Atlas machines were built: one for British Petroleum and the University of London, and one for the Atlas Computer Laboratory at Chilton near Oxford.
A derivative system was built by Ferranti for Cambridge University. Called the Titan, or Atlas 2, it had a different memory organisation and ran a time-sharing operating system developed by Cambridge University Computer Laboratory. Two further Atlas 2s were delivered: one to the CAD Centre in Cambridge (later called CADCentre, then AVEVA), and the other to the Atomic Weapons Research Establishment (AWRE), Aldermaston.
In mathematics, particularly topology, one describes a manifold using an atlas. An atlas consists of individual charts that, roughly speaking, describe individual regions of the manifold. If the manifold is the surface of the Earth, then an atlas has its more common meaning. In general, the notion of atlas underlies the formal definition of a manifold and related structures such as vector bundles and other fibre bundles.
The definition of an atlas depends on the notion of a chart. A chart for a topological space M (also called a coordinate chart, coordinate patch, coordinate map, or local frame) is a homeomorphism from an open subset U of M to an open subset of Euclidean space. The chart is traditionally recorded as the ordered pair .
An atlas for a topological space M is a collection of charts on M such that . If the codomain of each chart is the n-dimensional Euclidean space and the atlas is connected, then M is said to be an n-dimensional manifold.
A DJ mix or DJ mixset is a sequence of musical tracks typically mixed together to appear as one continuous track. DJ mixes are usually performed using a DJ mixer and multiple sounds sources, such as turntables, CD players, digital audio players or computer sound cards, sometimes with the addition of samplers and effects units, although it's possible to create one using sound editing software.
DJ mixing is significantly different from live sound mixing. Remix services were offered beginning in the late 1970s in order to provide music which was more easily beatmixed by DJs for the dancefloor. One of the earliest DJs to refine their mixing skills was DJ Kool Herc.Francis Grasso was the first DJ to use headphones and a basic form of mixing at the New York nightclub Sanctuary. Upon its release in 2000, Paul Oakenfold's Perfecto Presents: Another World became the biggest selling dj mix album in the US.
A DJ mix is often put together with music from genres that fit into the more general term electronic dance music. Other genres mixed by DJ includes hip hop, breakbeat and disco. Four on the floor disco beats can be used to create seamless mixes so as to keep dancers locked to the dancefloor. Two of main characteristics of music used in dj mixes is a dominant bassline and repetitive beats. Music mixed by djs usually has a tempo which ranges from 120 bpm up to 160 bpm.
WWFS (102.7 FM) is a New York City hot adult contemporary radio station owned and operated by CBS Radio. WWFS' studios are in the combined CBS Radio facility in the West Soho section of Manhattan, and its transmitter sits atop the Empire State Building.
WWFS is best remembered for its previous incarnation, rock music-formatted WNEW-FM. The station shared the WNEW call letters between 1958 and 1986 with former sister AM station WNEW (1130 kHz) and television station WNEW-TV (channel 5), with all being owned by Metromedia. After WNEW-TV was sold to the News Corporation in 1986 (and became WNYW), and the AM station was sold to Bloomberg L.P. in 1992 (and became WBBR), 102.7 FM retained the WNEW-FM callsign until it was changed in 2007. CBS Radio has since reused the WNEW call sign; the present-day WNEW-FM in the Washington, D.C., area is connected to this station only through their common ownership.
WWFS broadcasts in the HD Radio format.
The 102.7 FM frequency was first assigned in the mid-1940s as WNJR-FM from Newark, New Jersey. Intended to be a simulcasting sister to WNJR (1430 AM, now WNSW), the FM station never made it to the air despite being granted several extensions of its construction permit. WNJR gave up and turned in the FM license to the Federal Communications Commission (FCC) in 1953.
KMXV ("Mix 93.3") is a Top 40 (CHR) station based in Kansas City, Missouri, United States. The Steel City Media outlet operates at 93.3 MHz with an ERP of 100 kW. Its current slogan is "Kansas City's #1 Hit Music Station". It is also one of two Top 40's competing in the Kansas City Metropolitan Area, the other being KCHZ. The station's studios are located at Westport Center in Midtown Kansas City, and the transmitter site is in the city's East Side.
The station was sold off by CBS Radio to Wilks Broadcasting in November 2006 as part of a nationwide reduction of radio stations by CBS. On June 12, 2014, Wilks announced that it is selling its Kansas City cluster (of which KMXV is part of) to Pittsburgh-based Steel City Media. The sale was approved on September 26, 2014, and was consummated on September 30.
The station began in 1958 as KCMK-FM (Kansas City, Missouri/Kansas), a classical station, but had several format changes (primarily country) over the next sixteen years. County DJ Jack Wesley "Cactus Jack" Call was at the station (from KCKN) for one week when he was killed on January 25, 1963 in a car crash. Singer Patsy Cline sang at a benefit for him at Memorial Hall (Kansas City, Kansas) on March 3, 1963. She was unable to leave Kansas City the next day because the airport was fogged in and was killed in a plane crash on March 5, 1963 en route from Fairfax Airport to Nashville.
