a region on a computer display screen which represents a separate computational process, controlled more or less independently from the remaining part of the screen, and having widely varying functions, from simply displaying information to comprising a separate conceptual screen in which output can be visualized, input can be controlled, program dialogs may be accomplished, and a program may be controlled independently of any other processes occurring in the computer. The window may have a fixed location and size, or (as in modern Graphical User Interfaces) may have its size and location on the screen under the control of the operator.

in computer an area on a display screen inside which a portion of a stored image or file can be displayed.

A working area on the desktop containing a software program. A window has a title bar at the top, containing the name of the program. Only one window can be active at one time. The active window receives input from the mouse and keyboard. A dialog box is a type of window.

A purpose made frame glazed and for fitment to a building or structure Raam

An opening in the wall of a building for the admission of light and air, usually closed by casements or sashes containing some transparent material, as glass, and capable of being opened and shut at pleasure.

The shutter, casement, sash with its fittings, or other framework, which closes a window opening.

The opening in a mat board through which the image will show. The window is usually 1/8 to 1/2 inch smaller than the image so the image can be taped to the back of the mat.

a framework of wood or metal that contains a glass windowpane and is built into a wall or roof to admit light or air

A user-defined area that is used to view a subset of the original map.

an analog of the APSE program's view of the terminal

an element on the workspace that presents a view of an object or conducts a dialog with the user

a user interface element and container that designers use to organize the information that users see in an application

a transparent protective device.

a transparent panel (as of an envelope) inserted in an otherwise opaque material

an infrared range that is optimized for optical transmissions

A transparent portion of a jib or mainsail.

a client-side object

a "concrete" object

an object and, as we know has properties whose values can be sent by sending certain messages

an object, because it encapsulates data and the functions that act on that data

A Fourier transform of a segment of a pure 400 Hz tone will produce a spectrum with a sharp peak at 400 Hz. But since the segment is finite, if the tone amplitude is constant, the spectrum will have "sidelobes" that extend over a wide range of frequencies. The sidelobes can be sharply reduced by contouring the amplitude with a "window." An example of the spectrum with and without a window is shown here[50 kb

Tinfoil strips dropped by Allied bombers to fog the German radars

1. Any device introduced into the atmosphere for producing an appreciable radar echo, usually for tracking some airborne device or as a tracer of wind. 2. A World War II code name for a type of radar-jamming device employed to confuse the operators of enemy radars (also referred to by the code names of rope, chaff , and clutter ). One type of window consists of packages containing thousands of small strips of paperbacked tinfoil which may be dropped from aircraft and balloons, ejected from rockets, and carried within balloons. The packages burst open upon ejection, scattering the tinfoil widely, producing a radar echo which looks like a small shower or a tight formation of aircraft on plan-position-indicator scopes. 3. Any gap in a linear continuum, as atmospheric windows , ranges of wavelengths in the electromagnetic spectrum to which the atmosphere is transparent, or firing windows , intervals of time during which conditions are favorable for launching a spacecraft on a specific mission.

Term used to denote a region of the electromagnetic spectrum where the atmosphere does not absorb radiation strongly.

a box that appears on the monitor

a drawing region that is either onscreen or offscreen

an abstract drawing region

a "region," but anything can be a region

A cut facet on overlay paperweights.

a facet polished onto a piece of rough, as uncut diamonds are called, to enable a tactician to assess the interior of a stone before cutting it

An optical "see-through" effect observed in faceted gems that have a shallow pavilion angle and are not well proportioned. This causes the stone to look watery and lack brilliance. zinc A lustrous, bluish-white metal that is brittle at room temperature but malleable when heated. Zinc is used in a variety of alloys, including brass, bronze and white gold and is not easily oxidized even in damp air.

A small facet polished on a rough diamond, through its skin, to allow a diamanteer to observe and map any internal features of the diamond prior to cutting. Also an area of a gemstone which "leaks" light or colour usually due to poor, often shallow, cutting.

The parameters of grey scale chosen for image viewing. The window level is centred on the attenuation of the tissue in question. The window width refers to the range of other tissues demonstrated.

1. Test pattern in a form of white box on black or grey background. A change of window size provides an easy way to control the average picture level. 2. A mode of test pattern generation where the main test signal is gated by a window signal to provide.

(CT) The width of the range of Hounsfield numbers over which the grey scale is spread in a particular CT scan. The absolute position of the window is set by the level. For example if the level is 0 and the window is 200 then the grey scale extends from +100HU to -100HU, if the level is -200 and the window is 400 then the grey scale extends from 0HU to -400HU. In either case any tissue with a Hounsfield number above the upper window limit will appear as white and any tissue with a Hounsfield number bellow the lower window limit will appear as black.

The period of time between the expected first principal payment and the last anticipated principal payment for a specific REMIC tranche.

In a CMO bond, the period of time between the expected first payment of principal and the expected last payment of principal.

The period of time from receipt of first principal payment to the last.
