  3. Repeating decimal - Wikipedia

    en.wikipedia.org/wiki/Repeating_decimal

    A repeating decimal or recurring decimal is a decimal representation of a number whose digits are eventually periodic (that is, after some place, the same sequence of digits is repeated forever); if this sequence consists only of zeros (that is if there is only a finite number of nonzero digits), the decimal is said to be terminating, and is not considered as repeating.

  4. Aortic valve area calculation - Wikipedia

    en.wikipedia.org/wiki/Aortic_valve_area_calculation

    This gives an LV stroke volume of 3.14 * 24 = 75.40 cc. Divide the LV stroke volume, 75.40 cc by the Aortic Valve VTI, 50 cm and this gives an aortic valve area of 75.40 / 50 = 1.51 cm 2. The weakest aspect of this calculation is the variability in measurement of LVOT area, because it involves squaring the LVOT dimension.

  5. Experimental uncertainty analysis - Wikipedia

    en.wikipedia.org/wiki/Experimental_uncertainty...

    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. Using rules for the transformation of random variables [ 5 ] it can be shown that if the T measurements are Normally distributed, as in Figure 1, then the estimates of g follow another (complicated ...

  6. Splitting circle method - Wikipedia

    en.wikipedia.org/wiki/Splitting_circle_method

    In mathematics, the splitting circle method is a numerical algorithm for the numerical factorization of a polynomial and, ultimately, for finding its complex roots.It was introduced by Arnold Schönhage in his 1982 paper The fundamental theorem of algebra in terms of computational complexity (Technical report, Mathematisches Institut der Universität Tübingen).

  7. Mach number - Wikipedia

    en.wikipedia.org/wiki/Mach_number

    As the Mach number is defined as the ratio of two speeds, it is a dimensionless quantity. If M < 0.2–0.3 and the flow is quasi-steady and isothermal, compressibility effects will be small and simplified incompressible flow equations can be used. [1] [2]

  8. Big O notation - Wikipedia

    en.wikipedia.org/wiki/Big_O_notation

    Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. Big O is a member of a family of notations invented by German mathematicians Paul Bachmann, [1] Edmund Landau, [2] and others, collectively called Bachmann–Landau notation or asymptotic notation.

  9. Fibonacci sequence - Wikipedia

    en.wikipedia.org/wiki/Fibonacci_sequence

    Fibonacci numbers are used in a polyphase version of the merge sort algorithm in which an unsorted list is divided into two lists whose lengths correspond to sequential Fibonacci numbers—by dividing the list so that the two parts have lengths in the approximate proportion φ.
