Envelope \En"vel*ope\ (?; 277), Envelop \En*vel"op\ (?; 277), n.
That which envelops, wraps up, encases, or surrounds; a wrapper; an inclosing cover; esp., the cover or wrapper of a document, as of a letter.
(Astron.) The nebulous covering of the head or nucleus of a comet; -- called also coma.
(Fort.) A work of earth, in the form of a single parapet or of a small rampart. It is sometimes raised in the ditch and sometimes beyond it.
(Geom.) A curve or surface which is tangent to each member of a system of curves or surfaces, the form and position of the members of the system being allowed to vary according to some continuous law. Thus, any curve is the envelope of its tangents.
4. A set of limits for the performance capabilities of some type of machine, originally used to refer to aircraft; -- it is often described graphically as a two-dimensional graph of a function showing the maximum of one performance variable as a function of another. Now it is also used metaphorically to refer to capabilities of any system in general, including human organizations, esp. in the phrase push the envelope. It is used to refer to the maximum performance available at the current state of the technology, and therefore refers to a class of machines in general, not a specific machine.
push the envelope to increase the capability of some type of machine or system; -- usually by technological development.
Douglas Harper's Etymology Dictionary
"a wrapper, an enclosing cover," specifically a prepared wrapper for a letter or other paper, 1705, from French enveloppe (13c.), a back-formation from envelopper "to envelop" (see envelop).
Etymology 1 n. A paper or cardboard wrapper used to enclose small, flat items, especially letters, for mailing. Etymology 2
vb. (context nonstandard English) (alternative spelling of envelop English)
n. a flat rectangular paper container for papers
any wrapper or covering
a curve that is tangent to each of a family of curves
a natural covering (as by a fluid); "the spacecraft detected an envelope of gas around the comet"
the maximum operating capability of a system; "test pilots try to push the envelope"
the bag containing the gas in a balloon [syn: gasbag]
An envelope is a common packaging item, usually made of thin flat material. It is designed to contain a flat object, such as a letter or card.
Traditional envelopes are made from sheets of paper cut to one of three shapes: a rhombus, a short-arm cross, or a kite. These shapes allow for the creation of the envelope structure by folding the sheet sides around a central rectangular area. In this manner, a rectangle-faced enclosure is formed with an arrangement of four flaps on the reverse side.
An envelope is the paper container used to hold a letter being sent by post.
Envelope may also refer to:
- Envelope (mathematics), a curve, surface, or higher-dimensional object defined as being tangent to a given family of lines or curves (or surfaces, or higher-dimensional objects, respectively)
- Viral envelope, the membranal covering surrounding the capsid of a virus
- Cell envelope of a bacterium, consisting of the cell membrane, cell wall and outer membrane
In applied science:
- Envelope (waves), a curve joining the peaks of an oscillating waveform or signal
- Envelope detector, an electronic circuit used to measure the envelope of a waveform
- ADSR envelope, the variation of a sound over time, as is used in sound synthesis
- Envelope (motion), a solid representing all positions that an object may occupy during its normal range of motion
- Flight envelope, the limits within which an aircraft can operate
- Building envelope, the exterior layer of a building that protects it from the elements
- Envelope (airships), the fabric skin covering the airship
- Envelopes (band), an indie/pop band from Sweden and France, based in the UK
- Envelope (film), a 2012 film
- Envelope (poetry), a poetic device in which a line or a stanza is repeated to enclose a section of verse
- Envelope (military) (also envelop) attacking one or both of the enemy's flanks to encircle the enemy
In geometry, an envelope of a family of curves in the plane is a curve that is tangent to each member of the family at some point. Classically, a point on the envelope can be thought of as the intersection of two "adjacent" curves, meaning the limit of intersections of nearby curves. This idea can be generalized to an envelope of surfaces in space, and so on to higher dimensions.
In mechanical engineering, an envelope is a solid representing all positions which may be occupied by an object during its normal range of motion.
Another (jargon) word for this is a "flop".
In physics and engineering, the envelope function of an oscillating signal is a smooth curve outlining its extremes. The envelope thus generalizes the concept of a constant frequency. The figure illustrates a modulated sine wave varying between an upper and a lower envelope. The envelope function may be a function of time, space, angle, or indeed of any variable.
Envelope is a 2012 American short film directed by Aleksy Nuzhny and stars Kevin Spacey. It is inspired by true events of Soviet publicist and writer Yevgeny Petrov.
Radar envelope is a critical Measure of Performance (MOP) identified in the Test and Evaluation Master Plan (TEMP). This is the volume of space where a radar system is required to reliably detect an object with a specific size and speed. This is one of the requirements that must be evaluated as part of the acceptance testing process.
Radar systems have natural deficiencies because the laws of physics create performance constraints that cannot be altered. The ambiguity function associated with pulse compression and scalloping associated with moving target indication are two examples.
Complete coverage requires radar at multiple locations and multiple different kinds of radar.
