Open cluster, a spherical collection of stars that orbits a galaxy in the galactic plane
Globular cluster, a spherical collection of stars whose orbit is either partially or completely in the halo of the parent galaxy. They are older, more densely populated, and contain more stars than open clusters.
Galaxy cluster, large gravitationally bound groups of galaxies, or groups of groups of galaxies
Supercluster, the largest gravitationally bound objects in the universe, composed of many galaxy clusters
Cluster mission, a European Space Agency mission to study the magnetosphere
Cluster was a constellation of four European Space Agency spacecraft which were launched on the maiden flight of the Ariane 5 rocket, Flight 501, and subsequently lost when that rocket failed to achieve orbit. The launch, which took place on Tuesday, 4 June 1996, ended in failure due to an error in the software design caused by assertions having been turned off, which in turn caused inadequate protection from integer overflow. This resulted in the rocket veering off its flight path 37 seconds after launch, beginning to disintegrate under high aerodynamic forces, and finally self-destructing by its automated flight termination system. The failure has become known as one of the most infamous and expensive software bugs in history. The failure resulted in a loss of more than US$370 million.
Cluster consisted of four 1,200 kilograms (2,600lb) cylindrical, spin-stabilised spacecraft, powered by 224 watt solar cells. The spacecraft were to have flown in a tetrahedral formation, and were intended to conduct research into the Earth's magnetosphere. The satellites would have been placed into highly elliptical orbits; 17,200 by 120,600 kilometres (10,700 by 74,900mi), inclined at 90 degrees to the equator.
Cluster is the eponymous debut studio album by Germanelectronic music outfit Cluster. It was recorded in 1971 and released the same year by record label Philips. It is also the only album on which Conrad Plank is credited as a member.
Cluster was recorded at Star-Studio in Hamburg, Germany in January 1971.
Cluster began a transition away from the discordant, proto-industrial sound of Kluster towards a more electronic sound. Instrumentation included a pair of organs, Hawaiian guitar, cello and audio generators, all played by Moebius and Roedelius and all of which were electronically treated by Conny Plank.
Cluster was released in 1971 by record label Philips; Cluster's only release for the label.
The album was reissued with new artwork and a new title, Cluster 71, by Sky Records in 1980. Cluster 71 was digitally remastered (from a vinyl source, not a tape) and reissued on CD in 1996 by Sky with new artwork: a total of three different cover designs for the album to date. It received its first U.S release in 2006 on the San Francisco based Water label. The Water reissue restored the original Philips cover art but retains the Cluster 71 name. A 1,000 copy limited remastered edition of Cluster 71 with the original Sky LP cover art was reissued by the Japanese Captain Trip label as a CD on September 20, 2007.
Multiple is an album by American saxophonistJoe Henderson, released in 1973 on Milestone. It was recorded mainly on January 30–31, 1973, but producer Keepnews stated there had also been a couple of additional recordings in February and April.
The early Seventies were a time of accommodation for jazz and rock. Joe Henderson even had a brief 1971 stint in the horn section of Blood, Sweat & Tears; and Larry Willis, keyboard player on this album, joined BS&T shortly after Henderson left. The stellar band assembled here shows more of these fusion leanings than it might if assembled today—one doubts that Henderson would ask Willis to play electric keyboards, or drummer Jack DeJohnette to place as much emphasis on funk rhythms. (Dave Holland, a current Henderson collaborator, still has his electric bass in mothballs.) This is not to discount Multiple's distinct energy and groove, or its uniqueness in Joe Henderson's discography with its overdubs (including the leader's vocals) and the brief presence of James "Blood" Ulmer. DeJohnette and Holland each contribute tunes, plus an infectious, uncoiling momentum that makes the date a most corgenial meeting of giants
A financial ratio or accounting ratio is a relative magnitude of two selected numerical values taken from an enterprise's financial statements. Often used in accounting, there are many standard ratios used to try to evaluate the overall financial condition of a corporation or other organization. Financial ratios may be used by managers within a firm, by current and potential shareholders (owners) of a firm, and by a firm's creditors. Financial analysts use financial ratios to compare the strengths and weaknesses in various companies. If shares in a company are traded in a financial market, the market price of the shares is used in certain financial ratios.
Ratios can be expressed as a decimal value, such as 0.10, or given as an equivalent percent value, such as 10%. Some ratios are usually quoted as percentages, especially ratios that are usually or always less than 1, such as earnings yield, while others are usually quoted as decimal numbers, especially ratios that are usually more than 1, such as P/E ratio; these latter are also called multiples. Given any ratio, one can take its reciprocal; if the ratio was above 1, the reciprocal will be below 1, and conversely. The reciprocal expresses the same information, but may be more understandable: for instance, the earnings yield can be compared with bond yields, while the P/E ratio cannot be: for example, a P/E ratio of 20 corresponds to an earnings yield of 5%.
