Tree is an album by Irish folk singer Johnny Duhan.
In computer science, a tree is a widely used abstract data type (ADT)--or data structure implementing this ADT--that simulates a hierarchical tree structure, with a root value and subtrees of children with a parent node, represented as a set of linked nodes.
A tree data structure can be defined recursively (locally) as a collection of nodes (starting at a root node), where each node is a data structure consisting of a value, together with a list of references to nodes (the "children"), with the constraints that no reference is duplicated, and none points to the root.
Alternatively, a tree can be defined abstractly as a whole (globally) as an ordered tree, with a value assigned to each node. Both these perspectives are useful: while a tree can be analyzed mathematically as a whole, when actually represented as a data structure it is usually represented and worked with separately by node (rather than as a list of nodes and an adjacency list of edges between nodes, as one may represent a digraph, for instance). For example, looking at a tree as a whole, one can talk about "the parent node" of a given node, but in general as a data structure a given node only contains the list of its children, but does not contain a reference to its parent (if any).
Tree is a 2001 album by Gaelic Storm.
Beggarman, Black is the Colour, New York Girl, An Poc Ar Buile, and Go Home Girl are traditionals. Beggarman, which is played fast, is a standard in their live set list and features a didgeridoo very prominently. Black is the Colour, sung by guitarist Steve Twigger, is very slow and mournful, reminiscent of the original composition from the previous album She Was the Prize. An Poc Ar Buile is the band's first venture in the Irish language. The song is normally slowly sung, but Gaelic Storm puts a twist into it by singing it fast, complete with hoots and hollers. Go Home, Girl is a faster tune about a girl who falls in love with a gypsy, only to have her advances turned down for an ironic reason.
Wind Mobile is a Canadian wireless telecommunications provider operated by Globalive. It was one of several new mobile carriers launched in Canada after a government initiative to encourage competition in the wireless sector, alongside Mobilicity (later acquired by Rogers Communications) and Public Mobile (later acquired by Telus). With 940,000 active subscribers, Wind is Canada's fourth-largest mobile operator.
Wind initially launched mobile data and voice services in the Greater Toronto and Hamilton Area, Ontario on December 16, 2009 and two days later in Calgary, Alberta. Since then, Southern Ontario has been the main target of network expansion: first with Ottawa in Q1 2011, and then with about half a dozen additional regions, the most recent being Brantford on July 3, 2014. In Western Canada, coverage was added to Edmonton, Alberta and has expanded around Edmonton to include Sherwood Park, Fort Saskatchewan, St. Albert and Edmonton International Airport; additionally, British Columbia was also added for most of Greater Vancouver area plus Abbotsford and Whistler.
Air (also sometimes called Wind) is often seen as a universal power or pure substance. Its fundamental importance to life can be seen in words such as aspire, inspire, perspire and spirit, all derived from the Latin spirare.
Air is one of the four classical elements in ancient Greek philosophy and science. According to Plato, it is associated with the octahedron; air is considered to be both hot and wet. The ancient Greeks used two words for air: aer meant the dim lower atmosphere, and aether meant the bright upper atmosphere above the clouds.Plato, for instance writes that "So it is with air: there is the brightest variety which we call aether, the muddiest which we call mist and darkness, and other kinds for which we have no name...." Among the early Greek Pre-Socratic philosophers, Anaximenes (mid-6th century BCE) named air as the arche. A similar belief was attributed by some ancient sources to Diogenes Apolloniates (late 5th century BCE), who also linked air with intelligence and soul (psyche), but other sources claim that his arche was a substance between air and fire.Aristophanes parodied such teachings in his play The Clouds by putting a prayer to air in the mouth of Socrates.
WIND Hellas, formerly STET Hellas, is an integrated telecommunications provider with headquarters in Athens, Greece. WIND is the 3rd largest mobile operator in Greece (after Cosmote and Vodafone) with more than 4.4 million active subscribers (September 2010).
STET Hellas originated in 1992 with the establishment of TELESTET, a subsidiary of the Italian company STET, now Telecom Italia. On September 30, 1992 the Greek Ministry of Transport and Communications issued a license to STET to create a national mobile telephony services network (GSM). The company invested the sum of 30 billion drachmas (about 88 million Euros) to create the network. This constituted one of the biggest investments in Greece since the end of the Second World War. Commercial operation started on June 29, 1993 when the first call from a mobile phone took place in the country.
In 1998 TELESTET was the first Greek mobile telephony company to be listed in international stock markets, the NASDAQ in New York City and the Amsterdam Stock Exchange.
