The Artist Placement Group (APG) was conceived by Barbara Steveni in London in 1965, [1] and established in 1966 as an artist-run organisation seeking to refocus art outside the gallery, predominantly through attaching an artist in a business or governmental context for a period of time. Then the participating artists would try to create and ...
Optical proximity correction ( OPC) is a photolithography enhancement technique commonly used to compensate for image errors due to diffraction or process effects. The need for OPC is seen mainly in the making of semiconductor devices and is due to the limitations of light to maintain the edge placement integrity of the original design, after ...
The New York State Commission of Correction is "empowered to visit and inspect all penal institutions and to promote humane and efficient administration of these institutions." [1] It's a part of the New York State Executive Department. [1] [2]
In acoustics, end correction is a short distance applied or added to the actual length of a resonance pipe, in order to calculate the precise resonant frequency of the pipe. The pitch of a real tube is lower than the pitch predicted by the simple theory. A finite diameter pipe appears to be acoustically somewhat longer than its physical length.
The prism is named for its inventors, the French instrument maker Ph. Pellin and professor of physiological optics André Broca. [1] The prism consists of a four-sided block of glass shaped as a right prism with 90°, 75°, 135°, and 60° angles on the end faces. Light enters the prism through face AB, undergoes total internal reflection from ...
Digital room correction (or DRC) is a process in the field of acoustics where digital filters designed to ameliorate unfavorable effects of a room's acoustics are applied to the input of a sound reproduction system. Modern room correction systems produce substantial improvements in the time domain and frequency domain response of the sound ...

Image Geometry Correction (often referred to as Image Warping) is the process of digitally manipulating image data such that the image’s projection precisely matches a specific projection surface or shape. [1] Image geometry correction compensates for the distortion created by off-axis projector or screen placement or non-flat screen surface ...
