  2. Light-time correction - Wikipedia

    en.wikipedia.org/wiki/Light-time_correction

    Light-time correction is a displacement in the apparent position of a celestial object from its true position (or geometric position) caused by the object's motion during the time it takes its light to reach an observer. Light-time correction occurs in principle during the observation of any moving object, because the speed of light is finite.

  3. Optical proximity correction - Wikipedia

    en.wikipedia.org/wiki/Optical_proximity_correction

    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 ...

  4. Pitch correction - Wikipedia

    en.wikipedia.org/wiki/Pitch_correction

    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.

  5. Camera lucida - Wikipedia

    en.wikipedia.org/wiki/Camera_lucida

    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.

  6. Holm–Bonferroni method - Wikipedia

    en.wikipedia.org/wiki/Holm–Bonferroni_method

    The simple Bonferroni correction rejects only null hypotheses with p-value less than or equal to , in order to ensure that the FWER, i.e., the risk of rejecting one or more true null hypotheses (i.e., of committing one or more type I errors) is at most . The cost of this protection against type I errors is an increased risk of failing to reject ...

  7. OR-Tools - Wikipedia

    en.wikipedia.org/wiki/OR-Tools

    Google OR-Tools is a free and open-source software suite developed by Google for solving linear programming (LP), mixed integer programming (MIP), constraint programming (CP), vehicle routing (VRP), and related optimization problems. OR-Tools is a set of components written in C++ but provides wrappers for Java, .NET and Python.

  8. Bauernfeind prism - Wikipedia

    en.wikipedia.org/wiki/Bauernfeind_prism

    The Bauernfeind prism is commonly used in microscope tubes and in geodesy to deviate the path to the eyepiece in order make the device more ergonomic. [5] More recent applications are glasses that deflect the viewing angle either downwards (for relaxed reading or watching TV [6] ), or upwards (as in belay glasses for watching a climber while ...

  9. Digital room correction - Wikipedia

    en.wikipedia.org/wiki/Digital_room_correction

    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 ...
