  3. Optical transfer function - Wikipedia

    en.wikipedia.org/wiki/Optical_transfer_function

    The MTF data versus spatial frequency is normalized by fitting a sixth order polynomial to it, making a smooth curve. The 50% cut-off frequency is determined and the corresponding spatial frequency is found, yielding the approximate position of best focus .

    The Mil-HDBK-217 reliability calculator manual in combination with RelCalc software (or other comparable tool) enables MTBF reliability rates to be predicted based on design. A concept which is closely related to MTBF, and is important in the computations involving MTBF, is the mean down time (MDT). MDT can be defined as mean time which the ...

    In finance, market depth is a real-time list displaying the quantity to be sold versus unit price. The list is organized by price level and is reflective of real-time market activity.

  7. Move-to-front transform - Wikipedia

    en.wikipedia.org/wiki/Move-to-front_transform

    The move-to-front (MTF) transform is an encoding of data (typically a stream of bytes) designed to improve the performance of entropy encoding techniques of compression. When efficiently implemented, it is fast enough that its benefits usually justify including it as an extra step in data compression algorithm .
