Dreamcast

The Dreamcast (Japanese: ドリームキャスト, Hepburn: Dorīmukyasuto) is a home video game console released by Sega on November 27, 1998 in Japan, September 9, 1999 in North America, and October 14, 1999 in Europe. It was the first in the sixth generation of video game consoles, preceding Sony's PlayStation 2, Nintendo's GameCube and Microsoft's Xbox. The Dreamcast is Sega's final home console, marking the end of the company's 18 years in the console market.

In contrast to the expensive hardware of the unsuccessful Sega Saturn, the Dreamcast was designed to reduce costs with "off-the-shelf" components, including a Hitachi SH-4 CPU and an NEC PowerVR2 GPU. Released in Japan to a subdued reception, the Dreamcast enjoyed a successful U.S. launch backed by a large marketing campaign, but interest in the system steadily declined as Sony built hype for the upcoming PlayStation 2. Sales did not meet Sega's expectations despite several price cuts, and the company continued to incur significant financial losses. After a change in leadership, Sega discontinued the Dreamcast on March 31, 2001, withdrawing from the console business and restructuring itself as a third-party publisher. 9.13 million Dreamcast units were sold worldwide.

Enigma (yacht)

Enigma (formerly ECO and Katana) is one of the world's largest private superyachts. According to Power and Motoryacht magazine, she is owned by Aidan Barclay, son of the British media tycoon David Barclay, who recently purchased the Telegraph newspaper. She was sold after her former owner, Larry Ellison, took delivery of Rising Sun, the 6th largest private yacht in the world. Measuring slightly more than 244 feet (or around 75 metres), Enigma was launched in 1991 and originally christened ECO by its former owner, Mexican mogul Emilio Azcárraga, founder and former CEO of TV and media conglomerate Televisa. Enigma is renowned for her design, including a pyramidal superstructure surrounded by convex windows and an agile design that enables her to achieve a maximum speed of 30 knots. The yacht contains 9 luxurious suites and the rear deck was originally designed to carry a Maule turboprop floatplane.

She was built by German shipyards Blohm & Voss.

Enigma is powered by two Deutz AG BV16M628 diesel engines each producing 5,000 horsepower and one GE LM1600 gas turbine producing 18,500 horsepower. Each engine drives its own water jet drive. Because of the amount of fuel consumed when using the turbine engine for full speed cruising, the owner also commissioned a fuel tanker to provide refueling capabilities mid-journey.

International Ultramarine Corps

The International Ultramarine Corps, formerly the Ultramarine Corps, is a fictional team of superheroes published by DC Comics. They first appeared in DC One Million #2 (November 1998), and were created by Grant Morrison and Howard Porter.

History

The Corps was created by the U.S. as a government-sponsored group of superhumans to rival the more independent Justice League. Led by General Wade Eiling, the original members of the team were Flow, 4-D, Pulse 8 and Warmaker One. During a fight with the JLA, the UMC realised that Eiling was dangerously insane and that they were on the wrong side; they then sided with the League against their leader.

Having developed a mistrust of governments, the Corps subsequently declared themselves independent of any and all nations and built a free-floating city in which to dwell, which they named Superbia and set in the air above the ruins of Montevideo. They put out a call to other disaffected superheroes to join them in their city, and received a number of responses from around the globe, although the total population and demographics of Superbia are unknown.

Traffic flow (computer networking)

In packet switching networks, traffic flow, packet flow or network flow is a sequence of packets from a source computer to a destination, which may be another host, a multicast group, or a broadcast domain. RFC 2722 defines traffic flow as "an artificial logical equivalent to a call or connection."RFC 3697 defines traffic flow as "a sequence of packets sent from a particular source to a particular unicast, anycast, or multicast destination that the source desires to label as a flow. A flow could consist of all packets in a specific transport connection or a media stream. However, a flow is not necessarily 1:1 mapped to a transport connection." Flow is also defined in RFC 3917 as "a set of IP packets passing an observation point in the network during a certain time interval."

Conceptual description

A flow can be uniquely identified by the following parameters within a certain time period:

Rapping

Rapping (or emceeing,MCing,spitting bars,or rhyming) is "spoken or chanted rhyming lyrics". The components of rapping include "content", "flow" (rhythm and rhyme), and "delivery". Rapping is distinct from spoken-word poetry in that it is performed in time to a beat. Rapping is often associated with and a primary ingredient of hip-hop music, but the origins of the phenomenon can be said to predate hip-hop culture by centuries. It can also be found in alternative rock such as that of Cake, gorrilaz and the Red Hot Chili Peppers. Rapping is also used in Kwaito music, a genre that originated in Johannesburg, South Africa, and is composed of hip-hop elements.

Rapping can be delivered over a beat or without accompaniment. Stylistically, rap occupies a gray area between speech, prose, poetry, and singing. The word (meaning originally "to hit") as used to describe quick speech or repartee predates the musical form. The word had been used in British English since the 16th century. It was part of the African-American dialect of English in the 1960s meaning "to converse", and very soon after that in its present usage as a term denoting the musical style. Today, the terms "rap" and "rapping" are so closely associated with hip-hop music that many use the terms interchangeably.
