    Sheppard's correction. In statistics, Sheppard's corrections are approximate corrections to estimates of moments computed from binned data. The concept is named after William Fleetwood Sheppard . Let be the measured kth moment, the corresponding corrected moment, and the breadth of the class interval (i.e., the bin width).

  3. Astigmatism - Wikipedia

    In some people, the external optics may have the greater influence, and in other people, the internal optics may predominate. Importantly, the axes and magnitudes of external and internal astigmatism do not necessarily coincide, but it is the combination of the two that by definition determines the overall optics of the eye.

    en.wikipedia.org/wiki/Heisler_Chart

    Heisler charts permit evaluation of the central temperature for transient heat conduction through an infinitely long plane wall of thickness 2L, an infinitely long cylinder of radius r o, and a sphere of radius r o. Each aforementioned geometry can be analyzed by three charts which show the midplane temperature, temperature distribution, and ...
