  2. Anderson's theory of faulting - Wikipedia

    en.wikipedia.org/wiki/Anderson's_Theory_of_Faulting

    Anderson's theory of faulting, devised by Ernest Masson Anderson in 1905, is a way of classifying geological faults by use of principal stress. [ 1 ] [ 2 ] A fault is a fracture in the surface of the Earth that occurs when rocks break under extreme stress. [ 3 ]

    The CPT code revisions in 2013 were part of a periodic five-year review of codes. Some psychotherapy codes changed numbers, for example 90806 changed to 90834 for individual psychotherapy of a similar duration. Add-on codes were created for the complexity of communication about procedures.

  4. Stress testing - Wikipedia

    en.wikipedia.org/wiki/Stress_testing

    The goal and objectives, the time frame, the stress test level and the total costs of the stress test are defined. Phase 2: Assessment, during which the stress test at the component and the system scope is performed, including fragility [12] and risk [13] analysis of the CIs for the stressors defined in Phase 1. The stress test can result in ...

    en.wikipedia.org/wiki/Cone_penetration_test

    A CPT truck operated by the USGS. Symbol used in drawings Simplified version of a cone penetrometer.. The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy.

  6. Fatigue testing - Wikipedia

    en.wikipedia.org/wiki/Fatigue_testing

    These tests usually determine the rate of crack growth per cycle / versus the stress intensity factor range =, where the minimum stress intensity factor corresponds to the minimum load for > and is taken to be zero for , and is the stress ratio = /. Standardised tests have been developed to ensure repeatability and to allow the stress intensity ...

  7. Modern searches for Lorentz violation - Wikipedia

    en.wikipedia.org/wiki/Modern_searches_for...

    Early models assessing the possibility of slight deviations from Lorentz invariance have been published between the 1960s and the 1990s. [3] In addition, a series of test theories of special relativity and effective field theories (EFT) for the evaluation and assessment of many experiments have been developed, including:

  8. Anderson–Darling test - Wikipedia

    en.wikipedia.org/wiki/Anderson–Darling_test

    The Anderson–Darling test is a statistical test of whether a given sample of data is drawn from a given probability distribution. In its basic form, the test assumes that there are no parameters to be estimated in the distribution being tested, in which case the test and its set of critical values is distribution-free. However, the test is ...

  9. Cardiac stress test - Wikipedia

    en.wikipedia.org/wiki/Cardiac_stress_test

    The nuclear stress test exhibits a sensitivity of 81% and a specificity ranging from 85 to 95%. [22] To arrive at the patient's post test likelihood of disease, the interpretation of the stress test result necessitates the integration of the patient's pretest likelihood with the test's sensitivity and specificity.
