  2. Sixth nerve palsy - Wikipedia

    en.wikipedia.org/wiki/Sixth_nerve_palsy

    Sixth nerve palsy, or abducens nerve palsy, is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve), which is responsible for causing contraction of the lateral rectus muscle to abduct (i.e., turn out) the eye. [1]

  3. Corrective Optics Space Telescope Axial Replacement

    en.wikipedia.org/wiki/Corrective_Optics_Space...

    The budgeted cost of the COSTAR was US$50,000,000. [5] To fit the COSTAR system onto the telescope, one of the other instruments had to be removed, and astronomers selected the High Speed Photometer to be sacrificed, which was the least important of the four axial detectors.

  4. Šidák correction - Wikipedia

    en.wikipedia.org/wiki/Šidák_correction

    The Šidák correction is derived by assuming that the individual tests are independent. Let the significance threshold for each test be α 1 {\displaystyle \alpha _{1}} ; then the probability that at least one of the tests is significant under this threshold is (1 - the probability that none of them are significant).

  5. Error analysis for the Global Positioning System - Wikipedia

    en.wikipedia.org/wiki/Error_analysis_for_the...

    Some military and expensive survey-grade civilian receivers calculate atmospheric dispersion from the different delays in the L1 and L2 frequencies, and apply a more precise correction. This can be done in civilian receivers without decrypting the P(Y) signal carried on L2, by tracking the carrier wave instead of the modulated code.

  6. Cunningham correction factor - Wikipedia

    en.wikipedia.org/wiki/Cunningham_correction_factor

    In fluid dynamics, the Cunningham correction factor, or Cunningham slip correction factor (denoted C), is used to account for non-continuum effects when calculating the drag on small particles. The derivation of Stokes' law , which is used to calculate the drag force on small particles, assumes a no-slip condition which is no longer correct at ...

  7. Tidal prism - Wikipedia

    en.wikipedia.org/wiki/Tidal_Prism

    A tidal prism is the volume of water in an estuary or inlet between mean high tide and mean low tide, [1] or the volume of water leaving an estuary at ebb tide. [2]The inter-tidal prism volume can be expressed by the relationship: P=H A, where H is the average tidal range and A is the average surface area of the basin. [3]

  8. Strabismus surgery - Wikipedia

    en.wikipedia.org/wiki/Strabismus_surgery

    The earliest successful strabismus surgery intervention is known to have been performed on 26 October 1839 by Johann Friedrich Dieffenbach on a 7-year-old esotropic child; a few earlier attempts had been performed in 1818 by William Gibson of Baltimore, a general surgeon and professor at the University of Maryland. [2]

  9. Value of life - Wikipedia

    en.wikipedia.org/wiki/Value_of_life

    It is also referred to as the cost of life, value of preventing a fatality (VPF), implied cost of averting a fatality (ICAF), and value of a statistical life (VSL). In social and political sciences , it is the marginal cost of death prevention in a certain class of circumstances.
