Haken (band)
Haken () are an English progressive metal band formed in 2007 by multi-instrumentalist Richard Henshall, guitarist Matthew Marshall, and vocalist Ross Jennings. While Henshall, Marshall, and Jennings first had the idea of forming Haken in 2004, they opted to pursue their instruments and songwriting first. Upon recruiting other members three years later, they eventually released the demo ''Enter the 5th Dimension'' in 2008, signing with Sensory Records and releasing their first album ''Aquarius'' in 2010. , they have released six studio albums, an EP, and two live albums. History Early years Richard Henshall, Matthew Marshall, and Ross Jennings had grown up as friends in their teenage years and first had the idea to form Haken in 2004, when they would regularly play together in "casual bedroom jams". Henshall mentioned on some occasions that "Haken" was the name of a fictional character he and some friends came up with in their school days, under the influence of alcohol or weed ...

Haken (employment)
is the Japanese term for temporary employees dispatched to companies by staffing agencies. Background The temporary staffing industry in Japan is regulated by the 1985 Worker Dispatch Law. The original aim of this law was to regulate the extra-legal system of subcontractor personnel dispatching that had become commonplace in the automobile and electronics industries.Protected Employment Economies, pp. 8-9 Designed to allow project-based work and temporary staffing in sectors plagued by shortages of highly skilled workers (e.g., software specialists), the 1985 law limited temporary staffing to a "white list" of 13 occupations. But subsequent revisions steadily expanded its range of application. Notably, the 1999 revision replaced the "white list" with a short "black list" of occupations where temporary staffing remained restricted. This had the effect of opening most of the labor market to the temporary staffing industry.Protected Employment Economies, p. 15 Finally, the 2004 rev ...

Haken Manifold
In mathematics, a Haken manifold is a compact, P²-irreducible 3-manifold that is sufficiently large, meaning that it contains a properly embedded two-sided incompressible surface. Sometimes one considers only orientable Haken manifolds, in which case a Haken manifold is a compact, orientable, irreducible 3-manifold that contains an orientable, incompressible surface. A 3-manifold finitely covered by a Haken manifold is said to be virtually Haken. The Virtually Haken conjecture asserts that every compact, irreducible 3-manifold with infinite fundamental group is virtually Haken. This conjecture was proven by Ian Agol. Haken manifolds were introduced by . proved that Haken manifolds have a hierarchy, where they can be split up into 3-balls along incompressible surfaces. Haken also showed that there was a finite procedure to find an incompressible surface if the 3-manifold had one. gave an algorithm to determine if a 3-manifold was Haken. Normal surfaces are ubiquitous in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eduard Haken
Eduard Haken (22 March 1910 – 12 January 1996, Prague) was a Czech operatic bass who had a lengthy career at the National Theatre in Prague during the 20th century. Although he mostly performed within his own nation, Haken did appear at a number of important international music festivals and opera houses in Europe while traveling with the National Theatre. He was also active as a concert soloist and recitalist. Haken possessed a dark and glossy voice that was agile and powerful enough to assail a wide array of parts from the dexterous bel canto repertoire to heavier dramatic roles. A fine actor with a good sense of comic timing, he also excelled in the basso buffo repertoire. His voice is preserved on numerous opera recordings made with the Supraphon record label. Biography Born in Šklin, Ukraine to parents of Czech descent, Haken initially pursued a career as a doctor and in fact passed his medical examinations in 1932. While a student he took singing lessons with D. Levytsk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermann Haken
Hermann Haken (born 12 July 1927) is physicist and professor emeritus in theoretical physics at the University of Stuttgart. He is known as the founder of synergetics. He is a cousin of the mathematician Wolfgang Haken, who proved the Four color theorem. He is a nephew of Werner Haken, a doctoral student of Max Planck. Biography After his studies in mathematics and physics in Halle (Saale) and Erlangen, receiving his PhD in mathematics in 1951 at the University of Erlangen and being guest lecturer at universities in the UK and US, Haken was appointed as a full professor in theoretical physics at the University of Stuttgart. His research has been in non linear optics (his specialities are laser physics, particle physics, statistical physics and group theory). Haken developed his institute in a relatively short time to be an international centre for laser theory, starting in 1960 when Theodore Maiman built the first experimental laser. The interpretation of the laser princip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rianne Ten Haken
Rianne ten Haken (born 27 November 1986) is a Dutch model. She was born to a Dutch Father and a Belgian mother in Lelystad, Flevoland, and began modeling after she won the 2001 Elite Model Look competition at the age of 15. In 2003, Rianne walked her first runways. In New York, she debuted at the Marc Jacobs, show and was subsequently picked up by clients. In December 2003 she landed her first major cover for Italian Vogue, photographed by Steven Meisel. That same month she also appeared on the cover of Numero photographed by Mert & Marcus. Rianne has worked with several famous fashion photographers as Steven Meisel, Craig McDean, Patrick Demarchelier and Peter Lindbergh Peter Lindbergh (born Peter Brodbeck; 23 November 1944 – 3 September 2019) was a German fashion photographer and film director.

Wolfgang Haken
Wolfgang Haken (June 21, 1928 – October 2, 2022) was a German American mathematician who specialized in topology, in particular 3-manifolds. Biography Haken was born in Berlin, Germany. His father was Werner Haken, a physicist who had Max Planck as a doctoral thesis advisor. In 1953, Haken earned a Ph.D. degree in mathematics from Christian-Albrechts-Universität zu Kiel (Kiel University) and married Anna-Irmgard von Bredow, who earned a Ph.D. degree in mathematics from the same university in 1959. In 1962, they left Germany so he could accept a position as visiting professor at the University of Illinois at Urbana-Champaign. He became a full professor in 1965, retiring in 1998. In 1976, together with colleague Kenneth Appel at the University of Illinois at Urbana-Champaign, Haken solved the four-color theorem. They proved that any two-dimensional map, with certain limitations, can be filled in with four colors without any adjacent “countries” sharing the same color. ...
