  2. Rule of replacement - Wikipedia

    en.wikipedia.org/wiki/Rule_of_replacement

    In logic, a rule of replacement [1] [2] [3] is a transformation rule that may be applied to only a particular segment of an expression. A logical system may be constructed so that it uses either axioms, rules of inference, or both as transformation rules for logical expressions in the system. Whereas a rule of inference is always applied to a ...

  3. Order of operations - Wikipedia

    en.wikipedia.org/wiki/Order_of_operations

    Furthermore, because many operators are not associative, the order within any single level is usually defined by grouping left to right so that 16/4/4 is interpreted as (16/4)/4 = 1 rather than 16/(4/4) = 16; such operators are referred to as "left associative".

  4. Experimental uncertainty analysis - Wikipedia

    The mean (vertical black line) agrees closely [4] with the known value for g of 9.8 m/s 2. It is sometimes possible to derive the actual PDF of the transformed data. In the pendulum example the time measurements T are, in Eq(2), squared and divided into some factors that for now can be considered constants.

  5. Hume-Rothery rules - Wikipedia

    en.wikipedia.org/wiki/Hume-Rothery_rules

    Hume-Rothery rules, named after William Hume-Rothery, are a set of basic rules that describe the conditions under which an element could dissolve in a metal, forming a solid solution. There are two sets of rules; one refers to substitutional solid solutions, and the other refers to interstitial solid solutions.

    en.wikipedia.org/wiki/Q-system_(Geotechnical...

    The numerical values of the class boundaries for the different rock mass qualities are subdivisions of the Q range on a logarithmic scale. The Q-value determines the quality of the rock mass, but the support of an underground excavation is based not only on the Q-value but is also determined by the different terms in the above equation. This ...

  9. Likelihood function - Wikipedia

    en.wikipedia.org/wiki/Likelihood_function

    Stated in terms of odds, Bayes' rule states that the posterior odds of two alternatives, ⁠ ⁠ and ⁠ ⁠, given an event ⁠ ⁠, is the prior odds, times the likelihood ratio. As an equation: O ( A 1 : A 2 ∣ B ) = O ( A 1 : A 2 ) ⋅ Λ ( A 1 : A 2 ∣ B ) . {\displaystyle O(A_{1}:A_{2}\mid B)=O(A_{1}:A_{2})\cdot \Lambda (A_{1}:A_{2}\mid ...
