Lux

The lux (symbol: lx) is the SI unit of illuminance and luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watts per square metre, but with the power at each wavelength weighted according to the luminosity function, a standardized model of human visual brightness perception. In English, "lux" is used in both singular and plural.

Explanation

Illuminance

Illuminance is a measure of how much luminous flux is spread over a given area. One can think of luminous flux (measured in lumens) as a measure of the total "amount" of visible light present, and the illuminance as a measure of the intensity of illumination on a surface. A given amount of light will illuminate a surface more dimly if it is spread over a larger area, so illuminance (lux) is inversely proportional to area when the luminous flux (lumens) is held constant.

Nyx

Nyx (English /ˈnɪks/;Ancient Greek: Νύξ, "Night";Latin: Nox) is the Greek goddess (or personification) of the night. A shadowy figure, Nyx stood at or near the beginning of creation, and mothered other personified deities such as Hypnos (Sleep) and Thanatos (Death), with Erebus (Darkness). Her appearances are sparse in surviving mythology, but reveal her as a figure of such exceptional power and beauty, that she is feared by Zeus himself.

Mythology and literature

Hesiod

In Hesiod's Theogony, Nyx is born of Chaos. With Erebus (Darkness), Nyx gives birth to Aether (Brightness) and Hemera (Day). Later, on her own, Nyx gives birth to Moros (Doom, Destiny), Ker (Destruction, Death), Thanatos (Death), Hypnos (Sleep), the Oneiroi (Dreams), Momus (Blame), Oizys (Pain, Distress), the Hesperides, the Moirai (Fates), the Keres, Nemesis (Indignation, Retribution), Apate (Deceit), Philotes (Friendship), Geras (Old Age), and Eris (Strife).

In his description of Tartarus, Hesiod locates there the home of Nyx, and the homes of her children Hypnos and Thanatos. Hesiod says further that Nyx's daughter Hemera (Day) left Tartarus just as Nyx (Night) entered it; continuing cyclicly, when Hemera returned, Nyx left. This mirrors the portrayal of Ratri (night) in the Rigveda, where she works in close cooperation but also tension with her sister Ushas (dawn).

Nox (platform)

NOX is a piece of the software-defined networking (SDN) ecosystem. Specifically, it’s a platform for building network control applications.

The first SDN technology to get real name recognition was OpenFlow, and NOX was initially developed at Nicira Networks side-by-side with OpenFlow — NOX was the first OpenFlow controller. Nicira donated NOX to the research community in 2008, and since then, it has been the basis for many and various research projects in the early exploration of the SDN space.

Final (competition)

The final of a competition is the match or round in which the winner of the entire event is decided.

In sports competitions following a knockout system, where only two individuals or teams compete in each match, the final is usually played between the winners of two semi-finals. However, if more than two entrants are required for each match, then qualification for the final may be through some other process such as winning heats.

The final is usually, but not always, the last match in a tournament to be played, and the winner of this match is declared the winner of the whole tournament. In many contests, the winner(s) and runner(s)-up receive gold and silver medals respectively. Another game, or competition, between the two players who lost in the semi-finals is done to determine who receives the bronze medal. Unusually, many teams (32 in recent years) qualify for the FIFA World Cup finals. These teams then play each other in various formats until the ultimate two 'finalists' play off for the gold and silver medals.

Final (band)

HIDDEN ERROR: Usage of "Instruments" is not recognized

Final is a project of Justin Broadrick, creator of the band Godflesh, which he started when he was just 13 years old. Unlike Godflesh, Final is primarily electronic in nature, taking on a space-like, dark ambient sound.

In 2006 Final performed across Europe, including a slot on the Supersonic Festival at the Custard Factory, Birmingham on 23 July, and as special guests supporting Isis on 24 July.
