Yaw Angle
The Euler angles are three angles introduced by Leonhard Euler to describe the orientation of a rigid body with respect to a fixed coordinate system.Novi Commentarii academiae scientiarum Petropolitanae 20, 1776, pp. 189–207 (E478PDF/ref> They can also represent the orientation of a mobile frame of reference in physics or the orientation of a general basis in 3-dimensional linear algebra. Alternative forms were later introduced by Peter Guthrie Tait and George H. Bryan intended for use in aeronautics and engineering. Chained rotations equivalence Euler angles can be defined by elemental geometry or by composition of rotations. The geometrical definition demonstrates that three composed ''elemental rotations'' (rotations about the axes of a coordinate system) are always sufficient to reach any target frame. The three elemental rotations may be extrinsic (rotations about the axes ''xyz'' of the original coordinate system, which is assumed to remain motionless), or intrins ...

Yaw (name)
Yaw is a masculine given name originating from the Akan people and their day naming system, meaning born on a Thursday in Akan language, following their day naming system. People born on particular days are supposed to exhibit the characteristics or attributes and philosophy, associated with the days. Yaw has the appellation "Preko" or "Opereba" meaning brave. Origin and meaning of Yaw In the Akan culture, day names are known to be derived from deities. Yaw originated from Yawoada the Day of Reproduction. Males named Yaw are known to be courageous and aggressive in a warlike manner (preko). They tend to be guarded, judgemental and appear to be ungrateful. Male variants of Yaw Day names in Ghana vary in spelling among the various Akan subgroups. The name is spelt Yaw by the Akuapem, Ashanti and Fante subgroups.{{Cite web, date=2019-11-09, title='Day born names' in Dagbani, Ewe and Fante, url=https://www.ghanaweb.com/GhanaHomePage/NewsArchive/Day-born-names-in-Dagbani-Ewe ...

Yaws
Yaws is a tropical infection of the skin, bones, and joints caused by the spirochete bacterium ''Treponema pallidum pertenue''. The disease begins with a round, hard swelling of the skin, in diameter. The center may break open and form an ulcer. This initial skin lesion typically heals after 3–6 months. After weeks to years, joints and bones may become painful, fatigue may develop, and new skin lesions may appear. The skin of the palms of the hands and the soles of the feet may become thick and break open. The bones (especially those of the nose) may become misshapen. After 5 years or more, large areas of skin may die, leaving scars. Yaws is spread by direct contact with the fluid from a lesion of an infected person. The contact is usually of a nonsexual nature. The disease is most common among children, who spread it by playing together. Other related treponemal diseases are bejel (''T. pallidum endemicum''), pinta (''T. carateum''), and syphilis (''T. p. pallidum''). Yaw ...

Yaw-Yan
Yaw-Yan, also called Sayaw ng Kamatayan (English:''Dance of Death''), is a Filipino martial art developed by Napoleon A. Fernandez and based on older Filipino martial arts. Since its inception in the 1970s, it has dominated the kickboxing scene in the Philippines and has proven very effective against other stand-up fighting arts. Yaw-Yan closely resembles Muay Thai, but differs in the hip-torquing motion as well as the downward-cutting nature of its kicks, and the emphasis on delivering attacks from long range (while Muay Thai focuses more on clinching). Yaw-yan practitioners participate in various Filipino mixed-martial arts tournaments such as the Universal Reality Combat Championship and Fearless Fighting. History The originator of Yaw-Yan is Napoleon A. Fernandez or "Master Nap", a native of Quezon province, who originally studied Jujutsu. The word ''Yaw-Yan'' was derived from the last two syllables of ''Sayaw ng Kamatayan'' meaning "Dance of Death". Fernandez had a backg ...

Yaw (god)
Yam (also ''Yamm''; Semitic: ) is the god of the sea in the Canaanite pantheon. He takes the role of the adversary of Baal in the Ugaritic ''Baal Cycle''. The deity's name derives from the Canaanite word for "Sea", and is one name of the Ugaritic god of Rivers and Sea. Also titled ''ṯpṭ nhr'' (" the Judge of the River"), he is also one of the '' 'ilhm'', or sons of El, the name given to the Levantine pantheon. Of all the gods, despite being the champion of El, Yam holds special hostility against Baal Hadad, son of Dagon. He is a deity of the sea and his palace is in the abyss associated with the depths, or Biblical tehom, of the oceans. Yam is the deity of the primordial chaos and represents the power of the sea, untamed and raging; he is seen as ruling storms and the disasters they wreak, and was an important divinity to the maritime Phoenicians. The gods cast out Yam from the heavenly mountain Sappan (modern Jebel Aqra; ''Sappan'' is cognate to '' Tsephon''). Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ellen Beach Yaw
Ellen Beach Yaw (September 14, 1869 – September 9, 1947) was an American coloratura soprano, best known for her concert career and extraordinary vocal range, and for originating the title role in Arthur Sullivan's ''The Rose of Persia'' (1899). Early life and career Yaw was born in the small town of Boston, near Buffalo, New York, the daughter of Ambrose Yaw, who manufactured cow and sheep bells. Her family moved to Los Angeles when she was very young, but her father died when she was a small child, and the family was very poor. Yaw began singing and composing songs as a child. She studied singing in America, first with her mother; then with Hervor Anna Sofia Torpadie, the wife of tenor Theodore Bjorksten; and then with baritone Enrico Delle Sedie. Yaw sang in concerts, beginning as a child in the 1880s, to make money to pay for singing lessons. Tours of the southern United States, California, England, Switzerland, and Germany followed, and on her return to America she ...

Yaw (aviation)
An aircraft in flight is free to rotate in three dimensions: '' yaw'', nose left or right about an axis running up and down; ''pitch'', nose up or down about an axis running from wing to wing; and ''roll'', rotation about an axis running from nose to tail. The axes are alternatively designated as ''vertical'', ''lateral'' (or ''transverse''), and ''longitudinal'' respectively. These axes move with the vehicle and rotate relative to the Earth along with the craft. These definitions were analogously applied to spacecraft when the first manned spacecraft were designed in the late 1950s. These rotations are produced by torques (or moments) about the principal axes. On an aircraft, these are intentionally produced by means of moving control surfaces, which vary the distribution of the net aerodynamic force about the vehicle's center of gravity. Elevators (moving flaps on the horizontal tail) produce pitch, a rudder on the vertical tail produces yaw, and ailerons (flaps on the wings ...

Yaws (web Server)
Yaws (Yet another web server) is a web server written in Erlang by Claes (klacke) Wikström. Yaws can be embedded into other Erlang-based applications or run as a regular standalone web server. Because Yaws uses Erlang's lightweight threading system, it performs well under high concurrency. A load test conducted in 2002 comparing Yaws and Apache found that with the hardware tested, Apache The Apache () are a group of culturally related Native American tribes in the Southwestern United States, which include the Chiricahua, Jicarilla, Lipan, Mescalero, Mimbreño, Ndendahe (Bedonkohe or Mogollon and Nednhi or Carrizaleño a ... 2.0.39 with the worker MPM failed at 4,000 concurrent connections, while Yaws continued functioning with over 80,000 concurrent connections.

Yaw Drive
The yaw drive is an important component of the horizontal axis wind turbines' yaw system. To ensure the wind turbine is producing the maximal amount of electric energy at all times, the yaw drive is used to keep the rotor facing into the wind as the wind direction changes. This only applies for wind turbines with a horizontal axis rotor. The wind turbine is said to have a yaw error if the rotor is not aligned to the wind. A yaw error implies that a lower share of the energy in the wind will be running through the rotor area. (The generated energy will be approximately proportional to the cosine of the yaw error). History When the windmills of the 18th century included the feature of rotor orientation via the rotation of the nacelle, an actuation mechanism able to provide that turning moment was necessary. Initially the windmills used ropes or chains extending from the nacelle to the ground in order to allow the rotation of the nacelle by means of human or animal power. Another ...
