  2. Laser - Wikipedia

    en.wikipedia.org/wiki/Laser

    A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission of radiation. [1] [2] The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles ...

  3. Laser-assisted new attachment procedure - Wikipedia

    en.wikipedia.org/wiki/Laser-assisted_new...

    Laser-assisted new attachment procedure ( LANAP) is a surgical therapy for the treatment of periodontitis, intended to work through regeneration rather than resection.

  4. Pressure-correction method - Wikipedia

    en.wikipedia.org/wiki/Pressure-correction_method

    The correction for the velocity that is obtained from the second equation one has with incompressible flow, the non-divergence criterion or continuity equation. is computed by first calculating a residual value , resulting from spurious mass flux, then using this mass imbalance to get a new pressure value. The pressure value that is attempted ...

  5. Laser beam machining - Wikipedia

    en.wikipedia.org/wiki/Laser_beam_machining

    Laser beam machining. Laser beam machining ( LBM) is a form of machining that uses heat directed from a laser beam. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. The high frequency of monochromatic light will fall on the surface, thus heating, melting and vaporizing the material due to the impinge of ...

  6. Family-wise error rate - Wikipedia

    en.wikipedia.org/wiki/Family-wise_error_rate

    The reason why this procedure controls the family-wise error rate for all the m hypotheses at level α in the strong sense is, because it is a closed testing procedure.

  7. Lift-off (microtechnology) - Wikipedia

    en.wikipedia.org/wiki/Lift-off_(microtechnology)

    The lift-off process in microstructuring technology is a method of creating structures (patterning) of a target material on the surface of a substrate (e.g. wafer) using a sacrificial material (e.g. photoresist ). It is an additive technique as opposed to more traditional subtracting technique like etching . The scale of the structures can vary ...

  8. Small incision lenticule extraction - Wikipedia

    en.wikipedia.org/wiki/Small_incision_lenticule...

    ReLEx Small incision lenticule extraction ( SMILE ), second generation of ReLEx Femtosecond lenticule extraction ( FLEx ), is a form of laser based refractive eye surgery developed by Carl Zeiss Meditec used to correct myopia, and cure astigmatism. Although similar to LASIK laser surgery, the intrastromal procedure uses a single femtosecond laser referenced to the corneal surface to cleave a ...

  9. Cointegration - Wikipedia

    en.wikipedia.org/wiki/Cointegration

    Cointegration. Cointegration is a statistical property of a collection (X1, X2, ..., Xk) of time series variables. First, all of the series must be integrated of order d (see Order of integration ). Next, if a linear combination of this collection is integrated of order less than d, then the collection is said to be co-integrated.
