  2. Numeric precision in Microsoft Excel - Wikipedia

    en.wikipedia.org/wiki/Numeric_precision_in...

    Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...

  3. Gurney equations - Wikipedia

    en.wikipedia.org/wiki/Gurney_equations

    A key simplifying assumption Gurney made was that there is a linear velocity gradient in the explosive detonation product gases; in situations where this is strongly violated, such as implosions, the accuracy of the equations is low.

    The following apply for the nuclear reaction: a + b ↔ R → c in the centre of mass frame , where a and b are the initial species about to collide, c is the final species, and R is the resonant state .

  6. 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.

  7. Nuclear reaction analysis - Wikipedia

    en.wikipedia.org/wiki/Nuclear_reaction_analysis

    Rutherford backscattering (RBS) reactions are elastic (Q = 0), and the interaction (scattering) cross-section σ given by the famous formula derived by Lord Rutherford in 1911. But non -Rutherford cross-sections (so-called EBS , elastic backscattering spectrometry ) can also be resonant: for example, the 16 O(α,α) 16 O reaction has a strong ...

    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 ...

    the Green–Naghdi rate of the Cauchy stress, and; the Zaremba-Jaumann rate of the Cauchy stress. [2] The adjacent figure shows the performance of various objective rates in a simple shear test where the material model is hypoelastic with constant elastic moduli. The ratio of the shear stress to the displacement is plotted as a function of time ...
