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 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.
List of Fullmetal Alchemist characters
The Fullmetal Alchemist manga and anime series feature an extensive cast of fictional characters created by Hiromu Arakawa. The story is set in a fictional universe within the 20th Century in which alchemy is one of the most advanced scientific techniques. Although they basically start the same, the first anime, midway through its run, begins to differ greatly from the original manga; characters that are killed early on in the manga survive to the end of the first anime and vice versa. The second anime's (Fullmetal Alchemist: Brotherhood) events, however, faithfully follow those from the manga.
The story follows the adventures of two alchemist brothers named Edward and Alphonse Elric. While trying to revive their mother, the brothers lost parts of their bodies, with Alphonse's soul being contained in a suit of armor, and Edward replacing his right arm and left leg with two sets of automail, a type of advanced prosthetic limb. Advised by Roy Mustang, an alchemist from the State Military, Edward becomes a State Alchemist, and starts traveling with Alphonse through the country of Amestris in order to find a way to recover their bodies. In their search, they hear of the Philosopher's Stone, a powerful alchemy artifact that the brothers can use to recover their bodies. However, after becoming a State Alchemist, Edward discovers that several members of the military are also attempting to get the stone, most notably humanoid creatures known as homunculi, who start chasing the Elric brothers.
List of Soul characters
A comprehensive list of characters from the Soul series of fighting games produced by Namco.
Overall conception and development
The Soul series is a weapon-based fighting game franchise developed by Namco Bandai's Project Soul division and consists of eight games: Soul Edge, Soulcalibur, Soulcalibur II, Soulcalibur III, Soulcalibur Legends, Soulcalibur IV, Soulcalibur: Broken Destiny and Soulcalibur V. Set in the 16th century, the plot of the games revolve around Soul Edge, a cursed sword able to possess its wielder and devour souls. Its sprit is called Inferno, and his avatar/host is called Nightmare. Soul Calibur, a holy sword and Soul Edge's antithesis, also has a spirit called Elysium.
Characters
With each character, their weapon was decided upon before other aspects were. The design was then built to revolve around it, starting with gender, then physical measurements, and lastly background details. Once established, appearance and movement were fleshed out by the team's concept artist and rendered as a 3D model by a design team that worked solely on the character. The completed model was then animated by a motion capture artist working directly with the team. During this phase the team additionally worked with the story creators, refining the character's own role in the plot as needed throughout development. In the course of the series, two characters have been an exception to the process: Johan Druer, a berserker exclusive to the Soulcalibur Japanese player's guide, and Necrid, a character co-produced with Todd McFarlane that appears in Soulcalibur II.

Works
Seven Deadly Sins series
The Seven Deadly Sins series from Simon & Schuster features seven morally bankrupt teenagers in a small California town. Each novel revolves around one of the sins and each character's transgressions specific to that sin. They follow the lives of Harper Grace, Beth Manning, Adam Morgan, Kane Geary, Miranda Stevens, Reed Sawyer, Katherine (Kaia) Sellers, and their French teacher, Jack Powell. Novels in the series are Lust, Envy, Pride, Wrath, Sloth, Gluttony, and Greed.
The series was made into a four-hour miniseries, which debuted on the Lifetime Movie Network on May 23 and 24, 2010.
