Since Galen states that he is using observations of monkeys ( human dissection was prohibited ) to give an account of what the body looks like, Vesalius could portray himself as using Galen's approach of description of direct observation to create a record of the exact details of the human body, since he worked in a time when human dissection was allowed.

When describing the lexicon a reductionist approach is used, trying to remain general while using a minimal description.

A mathematical model is a description of a system using mathematical concepts and language.

In 1990, in a paper entitled " Climate and Smoke: An Appraisal of Nuclear Winter ," TTAPS give a more detailed description of the short-and long-term atmospheric effects of a nuclear war using a three-dimensional model:

Most optical phenomena can be accounted for using the classical electromagnetic description of light.

A description using the approach of underspecification would not attempt to assign to a specific phoneme in some or all of these cases, although it might be assigned to an archiphoneme, written something like | A |, which reflects the two neutralized phonemes in this position.

The purpose of using pseudocode is that it is easier for people to understand than conventional programming language code, and that it is an efficient and environment-independent description of the key principles of an algorithm.

Wireless service providers may deploy equipment using any of several air interface and channel access methods, as long as the network meets the service description characteristics described in the standard.

One way is by intensional definition, using a rule or semantic description:

The main facility is the element, where the document can be described using Dublin Core metadata properties ( e. g., title, creator / author, subject, description, etc ).

An often stated ambition of systems biology is the modeling and discovery of emergent properties, properties of a system whose theoretical description is only possible using techniques which fall under the remit of systems biology.

* Layman's introduction: A simple description of using SFG techniques in language and literacy tuition

Dublin Core Metadata can be used for multiple purposes, from simple resource description, to combining metadata vocabularies of different metadata standards, to providing interoperability for metadata vocabularies in the Linked data cloud and Semantic web implementations.

Because markup languages, and more generally data description languages ( not necessarily textual markup ), are not programming languages ( they are data without instructions ), they are more easily manipulated than programming languages – for example, web pages are presented as HTML documents, not C code, and thus can be embedded within other web pages, displayed when only partially received, and so forth.

* Web-based Intranet and Internet Information and Applications: assures accessibility to web content, e. g., text description for any visuals such that users of with a disability or users that need assistive technology such as screen readers and refreshable Braille displays, can access the content.

The following is a list of published crawler architectures for general-purpose crawlers ( excluding focused web crawlers ), with a brief description that includes the names given to the different components and outstanding features:

It has come to be used as a general method for conceptual description or modeling of information that is implemented in web resources, using a variety of syntax formats.

According to the description on the BBC Radio 3 web site, " Dalton's adaptation builds on the film's themes: the madness of society, the inner workings of the human mind and the paranoia of a country in the aftermath of a war.

The UPnP description for a device is expressed in XML and includes vendor-specific manufacturer information like the model name and number, serial number, manufacturer name, URLs to vendor-specific web sites, etc.

Adding relevant keywords to a web page's meta data, including the title tag and meta description, will tend to improve the relevancy of a site's search listings, thus increasing traffic.

The brief description of the prizes awarded by the Academy are taken from the " priser ( Prizes )" section of their web site.

Thus, for example, a WSDL description of a remote web service can be viewed as a form of reference ; it includes a complete specification of how to locate and bind to a particular web service.

It is a description of what happens when a system embraces specialization and trade and " constitutes an information gathering process, able to call up, and put to use, widely dispersed information that no central planning agency, let alone any individual, could know as a whole, possess or control .” The result is an interconnected web where people can benefit from the actions and knowledge of those they don't know.

The following is a description of the book from No Starch Press ' web site.

Further, many web page elements are interactive, so description of and directions for manipulation of interactive elements in the parallel frame or frames can easily be followed.

The simple alternative for a side-by-side look at things is to embed the element of information being discussed within a single web page, with the result that if the description is not kept very short, the media element being described scrolls off the page while the description is being read.

In the past years, Iptscrae has even been utilized in computer peer groups through open-source language compilers, using not only transformation and hardware description languages, but also combining it with several other genres of computer languages to create an intertwined web of user-friendliness and application compatibility.
