biological definition of



Definitionism is a school of thought which considered that the correct explanation of a theory consists of concepts used by this theory is well defined. This approach has been criticized for his dismissal of the importance of ostensive definition.


High-definition television

High definition television describes television system provides an image resolution significantly higher resolution than the previous generation. The term has been used since 1936, but in modern times refers to the generation after the standard-definition television, often abbreviated as HDTV. This is the current standard video format used in most broadcasting, terrestrial television broadcasting, cable television, satellite television and Blu-ray discs and streaming video. HDTV may be transmitted in various formats: 720p 1280×720 progressive scan: 921.600 pixel ~0.92 megapixels per frame. 1080p 1920×1080 progressive scan: no broadcast standard for ATSC 1.0. 1080i 1920×1080 interlaced: 1.036.800 pixels ~1.04 MP in the field or 2.073.600 pixels ~2.07 MP per frame. Some countries also use non-standard CEA resolution, for example 1440×1080i resolution: pixels 777.600 ~0.78 MP in the field or 1.555.200 pixels ~1.56 MP per frame. At two megapixels per frame, HDTV provides about five times more pixels compared to standard definition SD channels. The increased resolution provides a clearer, more detailed image. In addition, progressive scan and high-frame rate the resulting image with less flicker and display rapid movement. HDTV as it is known today first began official broadcasting in 1989 in Japan, under the Muse / hi-Vision analog system. HDTV has been widely adopted worldwide in the late 2000s.


System V Interface Definition

The System V Interface Definition is a standard that describes the AT&amp,T UNIX System V behavior, including that of system calls, C libraries, available programs and devices. While it was not the first attempt at a standardizations document, it was an important effort of early standardization of UNIX in a period when UNIX variants were multiplying rapidly and portability was problematic at best. By 1986, AT&amp,T required conformance with SVID issue 2 if vendors were to actually brand their products "System V R3". By the 1990s, however, its importance was largely eclipsed by POSIX and the Single UNIX Specification, which were based in part upon the SVID. Part of the reason for this was undoubtedly their vendor-independent approach.


Field of definition

In mathematics, the field of definition of an algebraic variety V is essentially the smallest field to which the coefficients of the polynomials defining V can belong. Given polynomials, with coefficients in a field K, it may not be obvious whether there is a smaller field k, and other polynomials defined over k, which still define V. The question of the definition concerned with Diophantine geometry.


Counterfactual definiteness

In quantum mechanics, counterfactual definiteness is the ability to speak "meaningfully" of the definiteness of the results of measurements that have not been performed. The term "counterfactual definiteness" is used in discussions of physics calculations, especially those related to the phenomenon called quantum entanglement and those related to the Bell inequalities. In such discussions "meaningfully" means the ability to treat these unmeasured results on an equal footing with measured results in statistical calculations. It is this aspect of counterfactual definiteness that is of direct relevance to physics and mathematical models of physical systems and not philosophical concerns regarding the meaning of unmeasured results. "Counterfactual" may appear in physics discussions as a noun. What is meant in this context is "a value that can be measured, but, for whatever reason, was not."


Document type definition

A document type definition is a set of markup declarations that define a document type for a SGML-family markup language. The DTD defines the valid building blocks of an XML document. It defines the document structure with a list of checked elements and attributes. In a DTD can be embedded within the XML document or as external reference. XML uses a subset of SGML DTD. As of 2009, a new XML namespace-aware schema languages such as W3C XML schema and ISO relax NG pushed otd. Namespace-well-known version of the otd developed in the framework of the 9th international standard ISO DSDL. Otd persist in applications which need special publishing characters such as the XML and HTML character entity references, which derive from larger sets defined as part of ISO efforts SOAR.
