Imago

In biology, the imago is the last stage an insect attains during its metamorphosis, its process of growth and development; it also is called the imaginal stage, the stage in which the insect attains maturity. It follows the final ecdysis of the immature instars.

In a member of the Ametabola or Hemimetabola, in which metamorphosis is "incomplete", the final ecdysis follows the last immature or nymphal stage. In members of the Holometabola, in which there is a pupal stage, the final ecdysis follows emergence from the pupa, after which the metamorphosis is complete, although there is a prolonged period of maturation in some species.

The imago is the only stage during which the insect is sexually mature and, if it is a winged species, has functional wings. The imago often is referred to as the adult stage.

Members of the order Ephemeroptera (mayflies) do not have a pupal stage, but they briefly pass through an extra winged stage called the subimago. Insects at this stage have functional wings but are not yet sexually mature.

Imago (The Butterfly Effect album)

Imago is the second full-length album by the Brisbane band The Butterfly Effect. It was released on 17 June 2006. It debuted on the Australian ARIA album charts at number 2, the Butterfly Effect's first top 10 album and their highest charting album.

Background

The track "Phoenix", which was released to Australian radio in 2005 prior to the album's release, did not make the cut for Imago, but was released as a b-side on the "A Slow Descent" single.

Sound and composition

The sound of "Imago" is much more progressive than the previous album and is less heavy as well. The album shows the band have all but lost their earlier nu-metal influences which has made them more popular. Clint Boge's vocals are also much more refined and as a result, his range is higher and more diverse than the previous releases.

The opener "Imago" is an instrumental track.

Release and promotion

The first single from Imago, titled "A Slow Descent", was released on 10 June 2006. It debuted at number 18 on the Australian Singles Chart, and in its second week rose to number 9, giving the Butterfly Effect their first top 10 single. The release was celebrated by hosting a signing at Skinny's Records in the band's hometown of Brisbane on the release date of the new album. Imago debuted at No.2 on the ARIA album charts, only narrowly beaten by local alternative rock group Eskimo Joe. After only nine weeks of release, it was certified gold for sales in excess of 35,000 copies.

Component

Component may refer to:

Software

Component (UML)

A component in the Unified Modeling Language "represents a modular part of a system, that encapsulates its content and whose manifestation is replaceable within its environment. A component defines its behavior in terms of provided and required interfaces".

A component may be replaced by another if and only if their provided and required interfaces are identical. This idea is the underpinning for the plug-and-play capability of component-based systems and promotes software reuse.

As can be seen from the above definition, UML places no restriction on the granularity of a component. Thus, a component may be as small as a figures-to-words converter, or as large as an entire document management system.

Larger pieces of a system's functionality may be assembled by reusing components as parts in an encompassing component or assembly of components, and wiring together their required and provided interfaces." Such assemblies are illustrated by means of component diagrams.

Component-based software engineering

Component-based software engineering (CBSE) (also known as component-based development (CBD)) is a branch of software engineering that emphasizes the separation of concerns in respect of the wide-ranging functionality available throughout a given software system. It is a reuse-based approach to defining, implementing and composing loosely coupled independent components into systems. This practice aims to bring about an equally wide-ranging degree of benefits in both the short-term and the long-term for the software itself and for organizations that sponsor such software.

Software engineering practitioners regard components as part of the starting platform for service-orientation. Components play this role, for example, in web services, and more recently, in service-oriented architectures (SOA), whereby a component is converted by the web service into a service and subsequently inherits further characteristics beyond that of an ordinary component.

Components can produce or consume events and can be used for event-driven architectures (EDA).
