K correction. K correction converts measurements of astronomical objects into their respective rest frames. The correction acts on that object's observed magnitude (or equivalently, its flux ). Because astronomical observations often measure through a single filter or bandpass, observers only measure a fraction of the total spectrum, redshifted ...
Prism: Light the Way is a two-dimensional puzzle video game developed by British company Morpheme Game Studios. In the game, the player, with the help of "Bulboids" that emit light beams, must direct the correct color of light into the "Glowbos". To aid in this objective are a variety of mirrors, T-splitters, filter blocks, and Prisms ...
The Pediatric Risk of Mortality ( PRISM) score was developed from the Physiologic Stability Index (PSI) [1] to reduce the number of physiologic variables required for pediatric intensive-care unit (PICU) mortality risk assessment, from 34 (in the PSI) to 14, [2] and to obtain an objective weighting of the remaining variables. [citation needed ...
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 ...
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 ...
Camera lucida in use. A camera lucida is an optical device used as a drawing aid by artists and microscopists . The camera lucida projects an optical superimposition of the subject being viewed, onto the surface upon which the artist is drawing. The artist sees both scene and drawing surface simultaneously, as in a photographic double exposure.
The Program Assessment Rating Tool, or PART, was a program run through the United States Office of Management and Budget to rate the effectiveness of all federal programs, PART was instituted by President George W. Bush in 2002. It was discontinued by the Obama administration . PART was spearheaded by OMB Director Mitch Daniels.
Pitch correction. Pitch correction is an electronic effects unit or audio software that changes the intonation (highness or lowness in pitch) of an audio signal so that all pitches will be notes from the equally tempered system (i.e., like the pitches on a piano ). Pitch correction devices do this without affecting other aspects of its sound.
