  2. 1951 USAF resolution test chart - Wikipedia

    en.wikipedia.org/wiki/1951_USAF_resolution_test...

    A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.

  3. Architectural pattern book - Wikipedia

    en.wikipedia.org/wiki/Architectural_pattern_book

    A pattern book, or architectural pattern book, is a book of architectural designs, usually providing enough for non-architects to build structures that are copies or significant derivatives of major architect-designed works. A number of pattern books have been very influential in spreading architectural styles.

    [W 106] Additionally, "Wikipedia for Schools", the Wikipedia series of CDs / DVDs produced by Wikipedia and SOS Children, is a free selection from Wikipedia designed for education towards children eight to seventeen. [W 107] There have been efforts to put a select subset of Wikipedia's articles into printed book form. [246]

    en.wikipedia.org/wiki/Philips_circle_pattern

    Philips circle pattern was also used by Channel 7 from 1995 (when station was replacing its previously Telefunken FuBK [102] [103] which was used from 1982 until 1995) [104] [105] [106] until it switched to a 24/7 schedule on 11 March 2010. the Philips circle pattern was also used by MCOT HD (then as Channel 9) [107] from 1995 until it switched ...

  6. Test card - Wikipedia

    en.wikipedia.org/wiki/Test_card

    Test cards typically contain a set of patterns to enable television cameras and receivers to be adjusted to show the picture correctly (see SMPTE color bars).Most modern test cards include a set of calibrated color bars which will produce a characteristic pattern of "dot landings" on a vectorscope, allowing chroma and tint to be precisely adjusted between generations of videotape or network feeds.

  7. Fault coverage - Wikipedia

    en.wikipedia.org/wiki/Fault_coverage

    A fault coverage test passes when at least a specified percentage of all possible faults can be detected. If it does not pass, at least three options are possible. First, the designer can augment or otherwise improve the vector set, perhaps by using a more effective automatic test pattern generation tool. Second, the circuit may be re-defined ...

  8. Pattern (architecture) - Wikipedia

    en.wikipedia.org/wiki/Pattern_(architecture)

    Pattern in architecture is the idea of capturing architectural design ideas as archetypal and reusable descriptions. The term pattern in this context is usually attributed to Christopher Alexander, [1] an Austrian born American architect. The patterns serve as an aid to design cities and buildings. The concept of having collections of "patterns ...

  9. Basis path testing - Wikipedia

    en.wikipedia.org/wiki/Basis_path_testing

    The method normally uses McCabe cyclomatic complexity to determine the number of linearly independent paths and then generates test cases for each path thus obtained. [2] Basis path testing guarantees complete branch coverage (all edges of the control-flow graph ), but achieves that without covering all possible paths of the control-flow graph ...
