unmanned aerial vehicle

The UAV is an acronym for Unmanned Aerial Vehicle, which is an aircraft with no pilot on board. UAVs can be remote controlled aircraft (e.g. flown by a pilot at a ground control station) or can fly autonomously based on pre-programmed flight plans or more complex dynamic automation systems. UAVs are currently used for a number of missions, including reconnaissance and attack roles. For the purposes of this article, and to distinguish UAVs from missiles, a UAV is defined as being capable of controlled, sustained level flight and powered by a jet or reciprocating engine. In addition, a cruise missile can be considered to be a UAV, but is treated separately on the basis that the vehicle is the weapon. The acronym UAV has been expanded in some cases to UAVS (Unmanned Aircraft Vehicle System). The FAA has adopted the acronym UAS(Unmanned Aircraft System) to reflect the fact that these complex systems include ground stations and other elements besides the actual air vehicles.

Officially, the term 'Unmanned Aerial Vehicle' was changed to 'Unmanned Aircraft System' to reflect the fact that these complex systems include ground stations and other elements besides the actual air vehicles. The term UAS, however, is not widely used as the term UAV has become part of the modern lexicon. 

The military role of UAV is growing at unprecedented rates. In 2005, tactical and theater level unmanned aircraft (UA) alone, had flown over 100,000 flight hours in support of Operation ENDURING FREEDOM (OEF) and Operation IRAQI FREEDOM (OIF). Rapid advances in technology are enabling more and more capability to be placed on smaller airframes which is spurring a large increase in the number of SUAS being deployed on the battlefield. The use of SUAS in combat is so new that no formal DoD wide reporting procedures have been established to track SUAS flight hours.

第四週 Leonardo DiCaprio

 Leonardo DiCaprio

Few actors in the world have had a career quite as diverse as Leonardo DiCaprio's. DiCaprio has gone from relatively humble beginnings, as a supporting cast member of the sitcom Growing Pains and low budget horror movies, such as Critters 3, to a major teenage heartthrob in the 1990s, as the hunky lead actor in movies such as Romeo + Juliet and Titanic, to then become a leading man in Hollywood blockbusters, made by internationally renowned directors such as Martin Scorsese and Christopher Nolan.Leonardo Wilhelm DiCaprio was born November 11, 1974 in Los Angeles, California, the only child of Irmelin DiCaprio (née Indenbirken) and former comic book artist George DiCaprio. His father is of Italian and German descent, and his mother, who is German-born, is of German and Russian ancestry. His middle name, "Wilhelm", was his maternal grandfather's first name. Leonardo's father had achieved minor status as an artist and distributor of cult comic book titles, and was even depicted in several issues of American Splendor, the cult semiautobiographical comic book series by the late 'Harvey Pekar', a friend of George's. Leonardo's performance skills became obvious to his parents early on, and after signing him up with a talent agent who wanted Leonardo to perform under the stage name "Lenny Williams", DiCaprio began appearing on a number of television commercials and educational programs. DiCaprio began attracting the attention of producers, who cast him in bit part roles in a number of television series, such as Roseanne and The New Lassie, but it wasn't until 1991 that DiCaprio made his film debut in Critters 3, a low-budget horror movie.While DiCaprio's stint on Growing Pains was very short, as the sitcom was axed the year after he joined, it helped bring DiCaprio into the public's attention and, after the show ended, DiCaprio began auditioning for roles in which he would get the chance to prove his acting chops.Leonardo took up a diverse range of roles in the early 1990s, including a mentally challenged youth in What's Eating Gilbert Grape, a young gunslinger in The Quick and the Dead and a drug addict in one of his most challenging roles to date, "Jim Carroll", in The Basketball Diaries, a role which the late River Phoenix originally expressed interest in.
