  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

    P0rn is not a typo but an example of obfuscation, where people make a word harder for filtering software to understand while retaining its meaning to human readers. In mapping, it was common practice to include deliberate errors so that copyright theft could be identified. Typosquatting

  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. Differential GPS - Wikipedia

    en.wikipedia.org/wiki/Differential_GPS

    Differential GPS. Transportable DGPS reference station Baseline HD by CLAAS for use in satellite-assisted steering systems in modern agriculture. Differential Global Positioning Systems ( DGPSs) supplement and enhance the positional data available from global navigation satellite systems (GNSSs). A DGPS for GPS can increase accuracy by about a ...

  6. 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.

  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 ...

  9. 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.

    Power conditioner. A power conditioner (also known as a line conditioner or power line conditioner) is a device intended to improve the quality of the power that is delivered to electrical load equipment. The term most often refers to a device that acts in one or more ways to deliver a voltage of the proper level and characteristics to enable ...

    en.wikipedia.org/wiki/Apochromat

    An apochromat, or apochromatic lens (apo), is a photographic or other lens that has better correction of chromatic and spherical aberration than the much more common achromat lenses. The prefix apo-comes from the Greek preposition ἀπό-, meaning free from or away from.
