Blue

Blue is the colour between violet and green on the optical spectrum of visible light. Human eyes perceive blue when observing light with a wavelength between 450 and 495 nanometres. Blues with a higher frequency and thus a shorter wavelength gradually look more violet, while those with a lower frequency and a longer wavelength gradually appear more green. Pure blue, in the middle, has a wavelength of 470 nanometres. In painting and traditional colour theory, blue is one of the three primary colours of pigments, along with red and yellow, which can be mixed to form a wide gamut of colours. Red and blue mixed together form violet, blue and yellow together form green. Blue is also a primary colour in the RGB colour model, used to create all the colours on the screen of a television or computer monitor.

The modern English word blue comes from Middle English bleu or blewe, from the Old French bleu, a word of Germanic origin, related to the Old High German word blao. The clear sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. When sunlight passes through the atmosphere, the blue wavelengths are scattered more widely by the oxygen and nitrogen molecules, and more blue comes to our eyes. Rayleigh scattering also explains blue eyes; there is no blue pigment in blue eyes. Distant objects appear more blue because of another optical effect called atmospheric perspective.

Blue (queue management algorithm)

Blue is an scheduling discipline for the network scheduler developed by graduate student Wu-chang Feng for Professor Kang G. Shin at the University of Michigan and others at the Thomas J. Watson Research Center of IBM in 1999.

Functioning

Like random early detection (RED), it operates by randomly dropping or marking packet with explicit congestion notification mark before the transmit buffer of the network interface controller overflows. Unlike RED, however, it requires little or no tuning to be performed by the network administrator. A Blue queue maintains a drop/mark probability p, and drops/marks packets with probability p as they enter the queue. Whenever the queue overflows, p is increased by a small constant p_d, and whenever the queue is empty, p is decreased by a constant p_i < p_d.

If the mix of traffic on the interface does not change, p will slowly converge to a value that keeps the queue within its bounds with full link utilization.

Air (classical element)

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.

Greek and Roman tradition

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.

AIR (nightclub)

AIR was a 2,000 capacity superclub located in Digbeth, Birmingham in England. AIR originally started out life as a spray shop for buses, when in 2000 the building was bought by Godskitchen and converted into a club, originally named CODE. In 2003, CODE had a complete refit and was renamed AIR, with an extra room of music being added to the two already in use. The club features state-of-the-art lighting and sound systems and in addition to Saturday nights Godskitchen AIR has hosted parties by Helter Skelter, Babooshka, Polysexual, Raveology, Hardcore Til I Die & Atomic Jam.

AIR is situated in an area of Digbeth synonymous with club culture, the "Custard Factory Quarter", named after the nearby Custard Factory, a centre for music and arts. Adjacent to the Custard Factory is the HMV Institute (formerly the Digbeth Institute), the original home of Godskitchen.

The 20-year lease contract originally taken out by Angel Music Group still remains in place but since 6 May 2012 the club has remained closed due to the slow demise of the Godskitchen brand caused mainly by a lack of direction and leadership and the high costs imposed by the Custard Factory landlords making it far cheaper to keep the doors closed than to open them.

Air 500

Air 500 Inc. was a Canadian airline. Founded in 1988,the airline was operated a fleet of 1 Beechcraft 99, 1 Douglas C-47 and 1 Mitsubishi MU-2. It ceased operations in April 2007.
