USS Nimitz (CVN-68) is a supercarrier of the United States Navy, and the lead ship of her class. One of the largest warships in the world, she was laid down, launched and commissioned as CVAN-68 but was redesignated CVN 68 (nuclear-powered multimission aircraft carrier) on 30 June 1975 as part of the fleet realignment.
The ship was named for World War II Pacific fleet commander Chester W. Nimitz, who was the Navy’s third fleet admiral. Nimitz had her homeport at Naval Station Norfolk until 1987, when she was relocated to Puget Sound Naval Shipyard in Bremerton, Washington. Following her Refueling and Complex Overhaul in 2001, her homeport was changed to NAS North Island in San Diego, California. The home port of Nimitz was again moved to Naval Station Everett in 2012.
In January 2015 Nimitz changed homeport from Naval Station Everett to Naval Base Kitsap.
Nimitz was authorized by Congress in fiscal year 1967 and Newport News Shipbuilding and Dry Dock Co. in Newport News, Virginia was awarded the $106.5 million (equivalent to $755.81 million today). The keel was laid down 22 June 1968. It was christened on 13 May 1972 by Catherine Nimitz Lay, the daughter of the late Admiral Nimitz. Nimitz was delivered to the Navy in 1975, and was commissioned at Naval Station Norfolk on 3 May 1975 by President Gerald Ford.
FSX may refer to:
Microsoft Flight Simulator X (abbreviated to FSX) is a 2006 flight simulation computer game originally developed and published by Microsoft Game Studios for Microsoft Windows. It is the sequel to Microsoft Flight Simulator 2004 and the tenth and most current installment of the Microsoft Flight Simulator series, which was first released in 1982. It is built on an upgraded graphics rendering engine, showcasing DirectX 10 features and was marketed by Microsoft as the most important technological milestone in the series to date. FSX is the first version in the series to be released on DVD media.
In December 2012, over six years after its release, the FSX multiplayer matchmaking system over the GameSpy network was discontinued. On July 9, 2014, Dovetail Games, the developer of Train Simulator, announced that it signed a licensing agreement with Microsoft to continue development on FSX and the production of new content. On December 18, 2014, the FSX: Steam Edition version of the simulator was made available through digital distribution via Steam. The updated release of FSX includes support for Windows 8.1 and later, along with updated hosting of FSX multiplayer features through Steam.
Operation or Operations may refer to:
A military operation is the coordinated military actions of a state, or a non-state actor, in response to a developing situation. These actions are designed as a military plan to resolve the situation in the state's favor. Operations may be of a combat or non-combat nature and are referred to by a code name for the purpose of national security. Military operations are often known for their more generally accepted common usage names than their actual operational objectives.
Military operations can be classified by the scale and scope of force employment, and their impact on the wider conflict. The scope of military operations can be:
Musical set theory provides concepts for categorizing musical objects and describing their relationships. Many of the notions were first elaborated by Howard Hanson (1960) in connection with tonal music, and then mostly developed in connection with atonal music by theorists such as Allen Forte (1973), drawing on the work in twelve-tone theory of Milton Babbitt. The concepts of set theory are very general and can be applied to tonal and atonal styles in any equally tempered tuning system, and to some extent more generally than that.
One branch of musical set theory deals with collections (sets and permutations) of pitches and pitch classes (pitch-class set theory), which may be ordered or unordered, and can be related by musical operations such as transposition, inversion, and complementation. The methods of musical set theory are sometimes applied to the analysis of rhythm as well.
Although musical set theory is often thought to involve the application of mathematical set theory to music, there are numerous differences between the methods and terminology of the two. For example, musicians use the terms transposition and inversion where mathematicians would use translation and reflection. Furthermore, where musical set theory refers to ordered sets, mathematics would normally refer to tuples or sequences (though mathematics does speak of ordered sets, and although these can be seen to include the musical kind in some sense, they are far more involved).
