  2. Corrective and preventive action - Wikipedia

    en.wikipedia.org/wiki/Corrective_and_preventive...

    Correction is the action to eliminate a detected nonconformity or nonconformance. Preventive action includes the prediction of problems and attempts to avoid such occurrences (fail-safe) through self-initiated actions and analysis related to the processes or products.

  3. Typographical error - Wikipedia

    en.wikipedia.org/wiki/Typographical_error

    When using a typewriter without correction tape, typos were commonly struck out with another character such as a strikethrough. This saved the typist the trouble of retyping the entire page to eliminate the error, but as evidence of the typo remained, it was not aesthetically pleasing.

  4. Error detection and correction - Wikipedia

    en.wikipedia.org/wiki/Error_detection_and_correction

    Definitions. Error detection is the detection of errors caused by noise or other impairments during transmission from the transmitter to the receiver. Error correction is the detection of errors and reconstruction of the original, error-free data.

  5. Fine structure - Wikipedia

    en.wikipedia.org/wiki/Fine_structure

    Fine structure. Interference fringes, showing fine structure (splitting) of a cooled deuterium source, viewed through a Fabry–Pérot interferometer. In atomic physics, the fine structure describes the splitting of the spectral lines of atoms due to electron spin and relativistic corrections to the non-relativistic Schrödinger equation.

  6. Equalization (audio) - Wikipedia

    en.wikipedia.org/wiki/Equalization_(audio)

    Equalization (audio) A stereo graphic equalizer. For the left and right bands of the sound content, there are a series of vertical faders, which can be used to boost or cut specific frequency ranges. This equalizer is set to a smiley face curve, in which the mid-range sound frequencies are cut. Equalizers are also made in compact pedal-style ...

  7. Proofreading - Wikipedia

    en.wikipedia.org/wiki/Proofreading

    Proofreading is an iterative process of comparing galley proofs against the original manuscripts or graphic artworks to identify transcription errors in the typesetting process. [1] [2] In the past, proofreaders would place corrections or proofreading marks along the margins. [3] In modern publishing, material is generally provided in ...

  8. Corrective lens - Wikipedia

    en.wikipedia.org/wiki/Corrective_lens

    Corrective lens. A pair of contact lenses, positioned with the concave side facing upward. A corrective lens is a transmissive optical device that is worn on the eye to improve visual perception. The most common use is to treat refractive errors: myopia, hypermetropia, astigmatism, and presbyopia.

  10. Emmetropia - Wikipedia

    en.wikipedia.org/wiki/Emmetropia

    Emmetropia is the state of vision in which a faraway object at infinity is in sharp focus with the ciliary muscle in a relaxed state. That condition of the normal eye is achieved when the refractive power of the cornea and eye lens and the axial length of the eye balance out, which focuses rays exactly on the retina, resulting in perfectly sharp distance vision.
