  2. Fourier amplitude sensitivity testing - Wikipedia

    en.wikipedia.org/wiki/Fourier_amplitude...

    Fourier amplitude sensitivity testing (FAST) is a variance-based global sensitivity analysis method. The sensitivity value is defined based on conditional variances which indicate the individual or joint effects of the uncertain inputs on the output.

  3. Cycle detection - Wikipedia

    en.wikipedia.org/wiki/Cycle_detection

    A number of authors have studied techniques for cycle detection that use more memory than Floyd's and Brent's methods, but detect cycles more quickly. In general these methods store several previously-computed sequence values, and test whether each new value equals one of the previously-computed values.

  4. Rainflow-counting algorithm - Wikipedia

    en.wikipedia.org/wiki/Rainflow-counting_algorithm

    The method successively extracts the smaller interruption cycles from a sequence, which models the material memory effect seen with stress-strain hysteresis cycles. [1] This simplification allows the number of cycles until failure of a component to be determined for each rainflow cycle using either Miner's rule to calculate the fatigue damage ...

  5. Perceptual Evaluation of Audio Quality - Wikipedia

    en.wikipedia.org/wiki/Perceptual_Evaluation_of...

    Perceptual Evaluation of Audio Quality (PEAQ) is a standardized algorithm for objectively measuring perceived audio quality, developed in 1994–1998 by a joint venture of experts within Task Group 6Q of the International Telecommunication Union's Radiocommunication Sector . It was originally released as ITU-R Recommendation BS.1387 in 1998 and ...

  6. Cyclomatic complexity - Wikipedia

    en.wikipedia.org/wiki/Cyclomatic_complexity

    One common testing strategy, espoused for example by the NIST Structured Testing methodology, is to use the cyclomatic complexity of a module to determine the number of white-box tests that are required to obtain sufficient coverage of the module. In almost all cases, according to such a methodology, a module should have at least as many tests ...

  7. Kolmogorov–Smirnov test - Wikipedia

    en.wikipedia.org/wiki/Kolmogorov–Smirnov_test

    Illustration of the Kolmogorov–Smirnov statistic. The red line is a model CDF, the blue line is an empirical CDF, and the black arrow is the KS statistic.. In statistics, the Kolmogorov–Smirnov test (also K–S test or KS test) is a nonparametric test of the equality of continuous (or discontinuous, see Section 2.2), one-dimensional probability distributions.

  8. Verification and validation - Wikipedia

    en.wikipedia.org/wiki/Verification_and_validation

    Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.

  9. Soak testing - Wikipedia

    en.wikipedia.org/wiki/Soak_testing

    Soak testing involves testing a system with a typical production load, over a continuous availability period, to validate system behavior under production use. [ 1 ] It may be required to extrapolate the results, if not possible to conduct such an extended test.
