Unification (computer Science)
In logic and computer science, specifically automated reasoning, unification is an algorithmic process of solving equations between symbolic expression (mathematics), expressions, each of the form ''Left-hand side = Right-hand side''. For example, using ''x'',''y'',''z'' as variables, and taking ''f'' to be an uninterpreted function, the Singleton (mathematics), singleton equation set is a syntactic first-order unification problem that has the substitution as its only solution. Conventions differ on what values variables may assume and which expressions are considered equivalent. In first-order syntactic unification, variables range over first-order terms and equivalence is syntactic. This version of unification has a unique "best" answer and is used in logic programming and programming language type system implementation, especially in Hindley–Milner based type inference algorithms. In higher-order unification, possibly restricted to higher-order pattern unification, terms may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graph Theory
In mathematics and computer science, graph theory is the study of ''graph (discrete mathematics), graphs'', which are mathematical structures used to model pairwise relations between objects. A graph in this context is made up of ''Vertex (graph theory), vertices'' (also called ''nodes'' or ''points'') which are connected by ''Glossary of graph theory terms#edge, edges'' (also called ''arcs'', ''links'' or ''lines''). A distinction is made between undirected graphs, where edges link two vertices symmetrically, and directed graphs, where edges link two vertices asymmetrically. Graphs are one of the principal objects of study in discrete mathematics. Definitions Definitions in graph theory vary. The following are some of the more basic ways of defining graphs and related mathematical structures. Graph In one restricted but very common sense of the term, a graph is an ordered pair G=(V,E) comprising: * V, a Set (mathematics), set of vertices (also called nodes or points); * ...

Han Unification
Han unification is an effort by the authors of Unicode and the Universal Character Set to map multiple character sets of the Han characters of the so-called CJK languages into a single set of unified characters. Han characters are a feature shared in common by written Chinese ( hanzi), Japanese (kanji), Korean (hanja) and Vietnamese (chữ Hán). Modern Chinese, Japanese and Korean typefaces typically use regional or historical variants of a given Han character. In the formulation of Unicode, an attempt was made to unify these variants by considering them as allographsdifferent glyphs representing the same "grapheme" or orthographic unit hence, "Han unification", with the resulting character repertoire sometimes contracted to Unihan. Nevertheless, many characters have regional variants assigned to different code points, such as Traditional (U+500B) versus Simplified (U+4E2A). Rationale and controversy The Unicode Standard details the principles of Han unificat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unification (physics)
Unification of theories about observable fundamental phenomena of nature is one of the primary goals of physics. The two great unifications to date are Isaac Newton’s unification of gravity and astronomy, and James Clerk Maxwell’s unification of electromagnetism; the latter has been further unified with the concept of electroweak interaction. This process of "unifying" forces continues today, with the ultimate goal of finding a theory of everything. Unification of gravity and astronomy The "first great unification" was Isaac Newton's 17th century unification of gravity, which brought together the understandings of the observable phenomena of gravity on Earth with the observable behaviour of celestial bodies in space. His work is credited with laying the foundations of future endeavors for a grand unified theory. For example, it has been stated that "If we have to take any single individual as the originator of the quest for a unified theory of physics, and, by implication, t ...

Grand Unified Theory
A Grand Unified Theory (GUT) is any Mathematical model, model in particle physics that merges the electromagnetism, electromagnetic, weak interaction, weak, and strong interaction, strong fundamental interaction, forces (the three gauge theory, gauge interactions of the Standard Model) into a single force at high energy, energies. Although this Unification (physics), unified force has not been directly observed, many GUT models theorize its existence. If the unification of these three interactions is possible, it raises the possibility that there was a grand unification epoch in the Chronology of the universe#Very early universe, very early universe in which these three fundamental interactions were not yet distinct. Experiments have confirmed that at high energy, the electromagnetic interaction and weak interaction unify into a single combined electroweak interaction. GUT models predict that at even grand unification energy, higher energy, the strong and electroweak interaction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unified Field Theory
In physics, a Unified Field Theory (UFT) or “Theory of Everything” is a type of field theory that allows all fundamental forces of nature, including gravity, and all elementary particles to be written in terms of a single physical field. According to quantum field theory, particles are themselves the quanta of fields. Different fields in physics include vector fields such as the electromagnetic field, spinor fields whose quanta are fermionic particles such as electrons, and tensor fields such as the metric tensor field that describes the shape of spacetime and gives rise to gravitation in general relativity. Unified field theories attempt to organize these fields into a single mathematical structure. For over a century, the unified field theory has remained an open line of research. The term was coined by Albert Einstein, who attempted to unify his general theory of relativity with electromagnetism. Einstein attempted to create a classical unified field theory. Among othe ...

Unification (album)
''Unification'' is the second studio album by the German power metal band Iron Savior. It continues the science fiction story that began on the first album '' Iron Savior''. It is the only album to feature former Gamma Ray and Freedom Call drummer Dan Zimmermann. Story In the year 2110, Earth is controlled by the Iron Savior. The gigantic machine - built in Atlantis to defend the lost continent against its enemies, the so-called Alliance - still is mistaken. The computer-unit analysis identifies man as the destroyer of Atlantis. So it continues to carry out its prime directive: Protect Atlantis and conquer the Alliance. On Earth only a few people managed to hide from the bloodhounds of the Savior in the former Earth-Defense-Headquarters (E.D.H.) underneath the everlasting ice of Greenland. The machine, from the very first moment of its arrival, was transmitting signals directly to the Atlantic Ocean, North Africa, South America, and the Easter Islands. This behavior led some p ...

The Next Generation)
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee' ...

Undisputed Championship (boxing)
In boxing, the undisputed champion of a weight class (boxing), weight class is the boxer who simultaneously holds world titles from all major organizations recognized by each other and the International Boxing Hall of Fame. There are currently four major sanctioning bodies: World Boxing Association, WBA, World Boxing Council, WBC, World Boxing Organization, WBO, and International Boxing Federation, IBF. There were many undisputed champions before the number of major sanctioning bodies recognizing each other increased to four in 2007, but there have been only 23 boxers (11 male and 12 female) to hold all four titles simultaneously. History Prior to the 1960s, most champions were "undisputed", although the term was rarely used (it does not appear in one 1970 ''Boxing Dictionary''). Early boxing champions at various weight divisions were established by acclamation between 1880 and 1920. Once a consensus champion had been awarded the title, the championship could usually be taken only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Undisputed Championship (professional Wrestling)
A undisputed championship is a professional wrestling term for a world title that is the unquestioned top championship in a promotion, often formed from two world titles being unified or held by the same individual. The first undisputed champions The reported first undisputed champion was George Hackenschmidt, who won a series of tournaments in Europe, including a world championship tournament to win the original World Heavyweight Championship. Amongst the other tournaments he won were the annual major tournaments in Paris, France; Hamburg, Germany; St. Petersburg, Russia; and Berlin, Germany. Hackenschmidt also defeated European Greco-Roman Champion Tom Cannon on September 4, 1902, in Liverpool, England to become the first undisputed World Heavyweight Champion. The only other reigning champion with claim to the belt at the time was Tom Jenkins the American Heavyweight Championship, which unified the American Greco-Roman Championship with the American Catch-As-Catch Can ...

Semantic Unification
Semantic unification is the process of unifying lexically different concept representations that are judged to have the same semantic content (i.e., meaning). In business processes, the conceptual semantic unification is defined as "the mapping of two expressions onto an expression in an exchange format which is equivalent to the given expression". Semantic unification has since been applied to the fields of business processes and workflow management. In the early 1990s Charles Petri at Stanford University introduced the term "semantic unification" for business models, later references could be found in and later formalized in Fawsy Bendeck's dissertation. Petri introduced the term 'pragmatic semantic unification" to refer to the approaches in which the results are tested against a running application using the semantic mappings. In this pragmatic approach, the accuracy of the mapping is not as important as its usability. In general, semantic unification as used in business ...

Unification Church
The Unification Church () is a new religious movement, whose members are called Unificationists or sometimes informally Moonies. It was founded in 1954 by Sun Myung Moon in Seoul, South Korea, as the Holy Spirit Association for the Unification of World Christianity (HSA-UWC; ); in 1994, the organization changed its name to the Family Federation for World Peace and Unification (FFWPU; ). It has a presence in approximately 100 countries around the world. Its leaders are Moon (prior to his death) and his wife, Hak Ja Han, whom their followers honor with the title "True Parents". Moon's book, ''The Divine Principle'', informs the beliefs of the Unification Church. Moon list of messiah claimants, considered himself the Second Coming, Second Coming of Christ, claiming to complete the mission Jesus Christ was unable to because of his crucifixion: beginning a new ideal family, and a larger human lineage, free from sin.
