A condition in IR reflow soldering in which component bodies block the energy from certain areas of the board, resulting in incomplete melting of the solder paste at those points.

A condition occurring during etchback in which the dielectric material, in contact with the foil, is incompletely removed although acceptable etchback may have been achieved elsewhere.

A condition in which solder fails to wet the device leads during the wave-soldering process. Generally the trailing terminations of a component are affected, because the component body blocks the proper flow of solder. Requires proper component orientation to correct the problem.

A process in which values are moved between hardware locations and RAM locations, thereby allowing the program to monitor the contents of write-only hardware registers or check the inputs form read-only hardware registers.

A recovery technique in which current page contents are never overwritten. Instead, new pages are allocated and written while the pages whose values are being replaced are retained as shadow copies until they are no longer needed to support the restoration of the system state due to a transaction rollback.

A computer's system and video BIOS code is usually stored on ROM chips. Shadowing refers to the performance-enhancement technique that copies BIOS code to faster RAM chips in the upper memory area (above 640 KB) during the boot routine.

Shade, or gradation of light and color; shading.

Shading which makes the colour darker. Sometimes the word 'shading' is used to denote this but for the sake of clarity, on this site, I have called this shadowing to allow the use of shading as a general term for both highlighting and shadowing.

A dark or discoloured area that is visible through a pigmented coating.

A technique for encapsulating private knowledge when implementing an application programmer's interface (API). The public API procedure simply validates its arguments and calls the shadow procedure, which performs the actual functionality of the API. Following the recommended naming conventions, the shadow procedure name is identical to the public API name but includes an underscore.

The procedure, often used in dichotic presentations, in which a participant is asked to repeat aloud, word for word, only what she hears through one earphone.

An approach to mentoring in which the trainee follows the mentor around for a stated period of time. [15

(dance) similar to "mirroring" except the leader faces away from the follower, with the follower shadowing the leaderÕs movement (see "mirroring").

A lead-and-follow activity for movement exploration, in which the leader faces away from the follower, and the follower shadows the leader´s movement; effective in building trust and sensi-tivity between individuals or within a group where the leader and the follower are clearly identified.

An artifact representing weakness or absence of signals located beyond structures (e.g., calcium, stent struts) with high echo-reflectivity. This artifact can hinder imaging beyond strong reflectors.

A faint representation; an adumbration.

An air transmission problem that occurs when obstacles are in the path of the radio signal and causes it to vary in strength as the mobile station is roaming in the network.

The reduction in size or intensity of a sound wave due to decreasing transmissivity of sound waves by human head tissue versus air.

Reduction in the level of light hitting an object.

following surreptitiously; keeping under surveillance; "always on guard against shadowing submarines"

Following, mimicking, and interrupting behaviors that people with dementia may experience.

the act of following someone secretly

Spending time with someone in a particular field, observing how he or she works.

is one form of professional development where more experienced staff are assigned to "buddy" other staff. Also see shadowing.

A form of help where an adult assists a child to perform a task by modeling how to do the task, or parts of it, as the child attempts the task. The adult moves through the task with the child standing close to him but without touching the child or interfering with his movements.

The process of using lighting to create interesting shadow shapes, lighting can be used to project shadows of trees, plants, statues, etc. on horizontal and vertical surfaces.

Projecting the shadow, especially of a small tree or plant, on to a wall or similar background.
