Operation Sigma Sigma

The Sigma is an experimental glider developed in Britain from 1966 by a team led by Nicholas Goodhart. After disappointing performance during flight testing the Sigma was passed on to a Canadian group which carried out modifications, making the Sigma more competitive.

Design and development

Designed to compete in the 1970 World Championships, the team aimed to develop a wing that would climb well through a high lift coefficient and a large wing area, but equally had the "maximum possible reduction of area for cruise at low lift coefficients". At the same time for the minimum possible drag they aimed for "extensive" laminar flow. To achieve this they employed flaps that would alter both wing area and wing camber. Based on analysis of the nature of thermals encountered in cross-country flying, they reasoned that by having a slow turning circle, their sailplane could stay close to the central (and strongest) part of the thermal and gain maximum benefit.

Its unusual feature is its ability to vary its wing area using Fowler flaps. It had been tried before by the Hannover Akaflieg in 1938 with their AFH-4, the South African Beatty-Johl BJ-2 Assegai and the SZD Zefir gliders.

Sigma baryon

The Sigma baryons are a family of subatomic hadron particles which have a +2, +1 or −1 elementary charge or are neutral. They are baryons containing three quarks: two up and/or down quarks, and one third quark, which can be either a strange (symbols Σ+, Σ0, Σ−), a charm (symbols Σ++
c, Σ+
c, Σ0
c), a bottom (symbols Σ+
b, Σ0
b, Σ−
b) or a top (symbols Σ++
t, Σ+
t, Σ0
t) quark. However, the top Sigmas are not expected to be observed as the Standard Model predicts the mean lifetime of top quarks to be roughly 6975500000000000000♠5×10⁻²⁵ s. This is about 20 times shorter than the timescale for strong interactions, and therefore it does not form hadrons.

List

The symbols encountered in these lists are: I (isospin), J (total angular momentum), P (parity), u (up quark), d (down quark), s (strange quark), c (charm quark), t (top quark), b (bottom quark), Q (charge), B (baryon number), S (strangeness), C (charmness), B′ (bottomness), T (topness), as well as other subatomic particles (hover for name).

Six Sigma

Six Sigma is a set of techniques and tools for process improvement. It was introduced by engineer Bill Smith while working at Motorola in 1986.Jack Welch made it central to his business strategy at General Electric in 1995. Today, it is used in many industrial sectors.

Six Sigma seeks to improve the quality of the output of a process by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes. It uses a set of quality management methods, mainly empirical, statistical methods, and creates a special infrastructure of people within the organization, who are experts in these methods. Each Six Sigma project carried out within an organization follows a defined sequence of steps and has specific value targets, for example: reduce process cycle time, reduce pollution, reduce costs, increase customer satisfaction, and increase profits.

The term Six Sigma originated from terminology associated with statistical modeling of manufacturing processes. The maturity of a manufacturing process can be described by a sigma rating indicating its yield or the percentage of defect-free products it creates. A six sigma process is one in which 99.99966% of all opportunities to produce some feature of a part are statistically expected to be free of defects (3.4 defective features per million opportunities). Motorola set a goal of "six sigma" for all of its manufacturing operations, and this goal became a by-word for the management and engineering practices used to achieve it.

Oxygen (Marie Serneholt song)

"Oxygen" is the third single by the Swedish pop music singer Marie Serneholt, released from her first album Enjoy the Ride in 2006.

After so much speculation about Marie's third single, promotional copies of the song were sent to Swedish radios in the second week of October. The video was premiered on 26 October on Swedish Music Channels. The song had already been released for digital download on 9 October. No physical release was made for this single. The song peaked at number seventy-six, failing to chart inside the Top 60.

Music video

The video was filmed in Stockholm, Sweden, on 22 September and it was premiered on 26 October.

Serneholt posted on her official blog: "Yay!! My new video is done and i'm so happy and proud over it! Can't wait for you to see it! I'm so excited! I wrote this in the Swedish forum, but i just want to thank all of you who's supporting me and my music, this Monday i received my first prize here in Sweden:-) it is called Guldmobilen, and you get that prize when your song's been downloaded more than 10000 times from 3s portal. So THANK YOU!!!:-) A big hug to all of you! //Your Marie"

Oxygen (Baptiste Giabiconi album)

Oxygen is the debut album from French male model and singer Baptiste Giabiconi. It was released on 24 September 2012 on the My Major Company fan-supported record label. The album is in English except for the track "Speed of Light (L'amour et les étoiles)", which is bilingual with some additional French lyrics. It was produced by Pete Boxta Martin and recorded in London. It went straight into #1 on the SNEP official French Albums Chart dated 30 September 2012.

Oxygen (Hadouken! song)

"Oxygen" is a song by British new rave band Hadouken!. It was released as the second single from their third studio album Every Weekend on 7 November 2010. The EP was released later on 18 January 2011.

Background

"Oxygen" is the second of two songs (the other being "Mecha Love") that the band had confirmed to be released as singles in 2010, before the rest of their third album is recorded in January 2011.

The song was mistakenly released on Beatport on the same date as "Mecha Love", several weeks before the announced release date. To compensate for this, the official release date was pushed back into December and the release was extended into an EP.

Music video

The music video was first published through Hadouken!'s YouTube channel on 8 January 2011. It features scenes of a woman in a bath tub attached to wires while the band is performing the song. An alternate video for the song was also released on 27 January.
