  2. Quantum indeterminacy - Wikipedia

    en.wikipedia.org/wiki/Quantum_indeterminacy

    Indeterminacy in measurement was not an innovation of quantum mechanics, since it had been established early on by experimentalists that errors in measurement may lead to indeterminate outcomes. By the later half of the 18th century, measurement errors were well understood, and it was known that they could either be reduced by better equipment ...

  3. Quantum error correction - Wikipedia

    en.wikipedia.org/wiki/Quantum_error_correction

    That these codes allow indeed for quantum computations of arbitrary length is the content of the quantum threshold theorem, found by Michael Ben-Or and Dorit Aharonov, which asserts that you can correct for all errors if you concatenate quantum codes such as the CSS codes—i.e. re-encode each logical qubit by the same code again, and so on, on ...

  4. False positives and false negatives - Wikipedia

    en.wikipedia.org/wiki/False_positives_and_false...

    The false positive rate (FPR) is the proportion of all negatives that still yield positive test outcomes, i.e., the conditional probability of a positive test result given an event that was not present. The false positive rate is equal to the significance level. The specificity of the test is equal to 1 minus the false positive rate.

  5. Statically indeterminate - Wikipedia

    en.wikipedia.org/wiki/Statically_indeterminate

    A statically indeterminate structure can only be analyzed by including further information like material properties and deflections. Numerically, this can be achieved by using matrix structural analyses, finite element method (FEM) or the moment distribution method (Hardy Cross) .

  6. Observational error - Wikipedia

    en.wikipedia.org/wiki/Observational_error

    Random errors are errors in measurement that lead to measurable values being inconsistent when repeated measurements of a constant attribute or quantity are taken. Random errors create measurement uncertainty. Systematic errors are errors that are not determined by chance but are introduced by repeatable processes inherent to the system. [3]

  7. Standard addition - Wikipedia

    The silver concentration in the test sample is the x-intercept of the plot. The dilution factor is multiplied by this initial concentration to determine the original concentration. Matrix effects occur even with methods such as plasma spectrometry , which have a reputation for being relatively free from interferences.

  9. L'Hôpital's rule - Wikipedia

    en.wikipedia.org/wiki/L'Hôpital's_rule

    Here is a basic example involving the exponential function, which involves the indeterminate form ⁠ 0 / 0 ⁠ at x = 0: + = (+) = + = This is a more elaborate example involving ⁠ 0 / 0 ⁠ . Applying L'Hôpital's rule a single time still results in an indeterminate form.
