Multimedia

Multimedia is media that uses multiple forms of information content and information processing to inform or amuse the audience. Multimedia referred to the use of electronic media to store and experience multimedia content. Multimedia is similar to traditional mixed media in fine art, but with a broader scope. The term rich media is identical for interactive multimedia. Multimedia means that computer info can be represented through audio, graphics, image, video and animation in addition to traditional media (text and graphics). Hypermedia can be considered one particular multimedia application.

Multimedia may be generally divided into linear and non-linear categories. Linear dynamic content progresses without any navigation control for the observer such as a cinema presentation. Non-linear content offers user interactivity to control progress as used with a computer game or used in self-paced computer based training. Non-linear content is also known as hypermedia content.
Multimedia presentations can be exist or recorded. A recorded presentation may allocate interactivity via a navigation system. A live multimedia presentation may allow interactivity via interaction with the presenter or performer.

Ocean

Ocean covers almost three quarters of the surface of the Earth, and nearly half of the world's marine waters are over 3000 m deep.
This global, consistent body of salt water, called the World Ocean, is divided by the continents and archipelagos into the following four bodies, from the largest to the smallest: the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, and the Arctic Ocean, and, according to some authorities such as International Hydrographic Organization, a fifth ocean, the Southern Ocean.
Some geographers and some governments but not the US, recognizes the IHO as defining official water body names and boundaries. The IHO officially sanctioned the Southern Ocean name only in 2000, but its definition by a line of latitude has left its acceptance as a fifth ocean open to question. The National Geographic Society and some other leading geographers and cartographers continue to use "South Pacific", "South Atlantic", and "Indian" Ocean for the waters around Antarctica. A few Oceanographers recognize only four oceans also, treating the Arctic Ocean as a part of the Atlantic Ocean.

Transistor

The transistor is a solid state semiconductor device which can be used for amplification, switching, voltage stabilization, signal modulation and many other functions. It acts as a variable valve which, based on its input current (BJT) or input voltage (FET), allows a precise amount of current to flow through it from the circuit's voltage supply.In essence, a transistor have three terminals. A current or voltage applied through/across two terminals controls a larger current through the other terminal and the common terminal. In analog circuits, transistors are used in amplifiers. Analog circuits comprise audio amplifiers, stabilised power supplies and radio frequency amplifiers. In digital circuits, transistors function basically as electrical switches. Digital circuits include logic gates, RAM (random access memory) and microprocessors.Transistor was also the common name in the sixties for a transistor radio, a portable radio that used transistors (rather than vacuum tubes) as its active electronic components. This is still one of the dictionary definitions of transistor.

Artist amp

Artist amp refers to a postage stamp-like art form. It is similar to a Cinderella stamp, in that it is not valid for postage, but it differs from a forgery or a bogus stamp in that no intention is made to fool any post office or collector of stamps. The artist amp is intended to be a miniature art form which can depict or remember any subject its creator chooses.

Techniques for the creation of artist amps may or may not include perforating the boundaries of the piece to more resemble a stamp, as well as applying gum to the reverse side of the paper. Whole sheets of such stamps are often made at one time. The artwork can be hand-drawn or painted, lithographed or offset-printed, photographed, Xeroxed, rubber stamped, or even output by computer-driven printer.

Creators of art within this genre include Donald Evans, Anna Banana, Steve Smith and the surprisingly prolific New Zealander Bruce Henderson. Henderson's output spans more than three decades and encompasses an entire alternative universe of artist amp countries. These include the Sultanate of Occussi-Ambeno, the Kingdom of all the Sedan, the Sultanate of Upper Yafa, the People's Republic of Kemp land, the Free Vineland Republic, the Republic of Liegerland, the Republic of Port Maria, Tui Tui, Aldabra, Karenni, Raoul, the Land of Muggy, Terra Candella, Cryonica, Aramoana, Whangamomona, Laré, Nova Arcadia, the Antarctic Confederation and the Khanate of Bokhara. Henderson's artist amp world even has its own imaginary "United Nations," the "International Council of Independent States". His creations are sometimes identified as micro nations, however, being completely imaginary and without "participants", they do not fit the definition.

Delta Air Lines

Delta Air is a major U.S. airline headquartered in Atlanta, Georgia, operating a large domestic and international network that spans North America, South America, Europe, Asia, and the Caribbean.

Delta operates hubs at Atlanta, Cincinnati, New York-JFK, and Salt Lake City. Delta also has great operations in many other cities, including Boston, Columbus, Fort Lauderdale, Los Angeles, New York-LaGuardia, Orlando, and Washington-Reagan. Delta is also the foremost hauler in Florida. Its key worldwide gateways are Atlanta, Cincinnati, and New York-JFK.

In terms of passengers approved, Delta is the second-largest airline in the world. In terms of total operating revenues, Delta is the fourth-largest airline in the world As of September 1, 2005, Delta served 178 domestic cities in 46 states, Puerto Rico, and the U.S. Virgin Islands, as well as 71 international cities, including 10 future ones, in 45 countries.

Early history

Delta timetable from 1934
Delta Boeing 747, operated by Pan Am, at London Heathrow Airport in May 1974.The corporation has its roots in Huff Daland Dusters, which was founded in 1924 in Macon, Georgia by more than a few partners with Collett E. Woolman becoming the world's first aerial crop dusting company. Huff Daland moved to Monroe, Louisiana the following year. In 1928, Huff Daland Dusters was purchased by C.E. Woolman and renamed Delta Air military after the Mississippi Delta, where its route joined Dallas, Texas to Jackson, Mississippi, via Shreveport, Louisiana and Monroe. By 1934, Delta Air began mail service from Charleston to Fort Worth, including Atlanta, Augusta and other stops in Georgia.

In 1941, Delta enthused its headquarters from Monroe to Atlanta, Georgia, to center itself along its new way network that joined Chicago and New Orleans to Florida and Ohio which would later become a Delta hub. In the 1950s, Delta began flights from New Orleans to the Caribbean and Venezuela, becoming the number 2 U.S. carrier in the region after Pan Am and Braniff. On May 1, 1953, Delta combined with Chicago and Southern to enlarge routes in Midwest. In 1955 Delta introduced the "hub and spoke system" where flights are running scared to a central point then sent out to other cities. By the early 1960s, Delta's route network extended to the West Coast, and Dallas was emerging as its second hub city.
