Directed Set
In mathematics, a directed set (or a directed preorder or a filtered set) is a nonempty set A together with a reflexive and transitive binary relation \,\leq\, (that is, a preorder), with the additional property that every pair of elements has an upper bound. In other words, for any a and b in A there must exist c in A with a \leq c and b \leq c. A directed set's preorder is called a . The notion defined above is sometimes called an . A is defined analogously, meaning that every pair of elements is bounded below. Some authors (and this article) assume that a directed set is directed upward, unless otherwise stated. Other authors call a set directed if and only if it is directed both upward and downward. Directed sets are a generalization of nonempty totally ordered sets. That is, all totally ordered sets are directed sets (contrast ordered sets, which need not be directed). Join-semilattices (which are partially ordered sets) are directed sets as well, but not conversel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nintendo Direct
Nintendo Direct is a series of online presentation or live shows produced by Nintendo, where information regarding the company's upcoming content or franchises is presented, such as information about games and consoles. The presentations began in Japan and North America with the first edition on October 21, 2011, before later expanding to Europe, Australia, and South Korea. Format Nintendo Direct presentations vary in format between different presentations and regions. Regional differences Nintendo Directs generally come in both regional and international formats. International For subjects of a general worldwide appeal, a single Nintendo Direct is often localized for a simultaneous international broadcast. Usually, these will be recorded in Japanese and presented by a Japanese presenter. Prior to Nintendo president Satoru Iwata's death, he would host Directs in both English and Japanese, with other languages' presentations being subtitled. Upon Iwata's death, Nintendo ...

Direct Examination
The direct examination or examination-in-chief is one stage in the process of adducing evidence from witnesses in a court of law. Direct examination is the questioning of a witness by the lawyer/side/party that called such witness in a trial. Direct examination is usually performed to elicit evidence in support of facts which will satisfy a required element of a party's claim or defense. In direct examination, one is generally prohibited from asking leading questions. This prevents a lawyer from feeding answers to a favorable witness. An exception to this rule occurs if one side has called a witness, but it is either understood or becomes clear, that the witness is hostile to the calling lawyer's side of the controversy, the lawyer who called the witness may then ask the court to declare the person on the stand a hostile witness. If the court does so, the lawyer may thereafter ask witness leading questions during direct examination. The techniques of direct examination are t ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or '' voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power ...

DirectX
Microsoft DirectX is a collection of application programming interfaces (APIs) for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms. Originally, the names of these APIs all began with "Direct", such as Direct3D, DirectDraw, DirectMusic, DirectPlay, DirectSound, and so forth. The name ''DirectX'' was coined as a shorthand term for all of these APIs (the ''X'' standing in for the particular API names) and soon became the name of the collection. When Microsoft later set out to develop a gaming console, the ''X'' was used as the basis of the name Xbox to indicate that the console was based on DirectX technology. The ''X'' initial has been carried forward in the naming of APIs designed for the Xbox such as XInput and the Cross-platform Audio Creation Tool (XACT), while the DirectX pattern has been continued for Windows APIs such as Direct2D and DirectWrite. Direct3D (the 3D graphics API within DirectX) is widely used in the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mars Direct
Mars Direct is a proposal for a human mission to Mars which purports to be both cost-effective and possible with current technology. It was originally detailed in a research paper by Martin Marietta engineers Robert Zubrin and David Baker in 1990, and later expanded upon in Zubrin's 1996 book '' The Case for Mars''. It now serves as a staple of Zubrin's speaking engagements and general advocacy as head of the Mars Society, an organization devoted to the colonization of Mars. History Space Exploration Initiative On July 20, 1989, US President George H. W. Bush announced plans for what came to be known as the Space Exploration Initiative (SEI). In a speech on the steps of the National Air and Space Museum he described long-term plans which would culminate in a human mission to the surface of Mars. By December 1990, a study to estimate the project's cost determined that long-term expenditure would total approximately 450 billion dollars spread over 20 to 30 years. The "90 Da ...

Direct Limit
In mathematics, a direct limit is a way to construct a (typically large) object from many (typically smaller) objects that are put together in a specific way. These objects may be groups, rings, vector spaces or in general objects from any category. The way they are put together is specified by a system of homomorphisms ( group homomorphism, ring homomorphism, or in general morphisms in the category) between those smaller objects. The direct limit of the objects A_i, where i ranges over some directed set I, is denoted by \varinjlim A_i . (This is a slight abuse of notation as it suppresses the system of homomorphisms that is crucial for the structure of the limit.) Direct limits are a special case of the concept of colimit in category theory. Direct limits are dual to inverse limits, which are also a special case of limits in category theory. Formal definition We will first give the definition for algebraic structures like groups and modules, and then the general defi ...

Direct (Vangelis Album)
''Direct'' is a studio album by the Greek electronic composer Vangelis, released in 1988. The album marks a new development in Vangelis' music, during which Vangelis moved his creative base from London to Athens in Greece, and it was his first album recorded in Athens after relocation from London. Overview According to the album sleeve notes the album and its title are inspired by Vangelis' method of composing and recording, relying on spontaneity, with the compositional and recording process occurring simultaneously in the studio. This process was largely facilitated by the use of full spectrum of sound in the mixing and mastering process, due to custom MIDI performance systems designed for Vangelis and the Zyklus MIDI Performance System which was developed by technicians Bill Marshall and Pete Kellock. Release The CD tracks "Dial Out" and "Intergalactic Radio Station" were not on the LP. The LP has CD tracks 1-2-3-4-6 on side A, and CD tracks 7-8-10-11-9 on side B. In 2013 the ...
