  2. Repeating decimal - Wikipedia

    en.wikipedia.org/wiki/Repeating_decimal

    The repeating sequence of digits is called "repetend" which has a certain length greater than 0, also called "period". [5] In base 10, a fraction has a repeating decimal if and only if in lowest terms, its denominator has any prime factors besides 2 or 5, or in other words, cannot be expressed as 2 m 5 n, where m and n are non-negative integers.

  3. Atomic ratio - Wikipedia

    en.wikipedia.org/wiki/Atomic_ratio

    In laser physics however, the atomic ratio may refer to the doping ratio or the doping fraction. For example, theoretically, a 100% doping ratio of Yb : Y 3 Al 5 O 12 is pure Yb 3 Al 5 O 12 . The doping fraction equals,

  4. One-repetition maximum - Wikipedia

    en.wikipedia.org/wiki/One-repetition_maximum

    One repetition maximum can also be used as an upper limit, in order to determine the desired "load" for an exercise (as a percentage of the 1RM). Weight training protocols often use 1RM when programming to ensure the exerciser reaches resistance overload, especially when the exercise objective is muscular strength, endurance or hypertrophy .

  5. Binomial distribution - Wikipedia

    en.wikipedia.org/wiki/Binomial_distribution

    (These probabilities should sum to a value close to one, in order to encompass the entire sample space.) Then by using a pseudorandom number generator to generate samples uniformly between 0 and 1, one can transform the calculated samples into discrete numbers by using the probabilities calculated in the first step.

  6. Fiber volume ratio - Wikipedia

    en.wikipedia.org/wiki/Fiber_volume_ratio

    Porosity or void fraction is a measure of the void (i.e., "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0 and 100%.

  7. Hexadecimal - Wikipedia

    en.wikipedia.org/wiki/Hexadecimal

    Hexadecimal (also known as base-16 or simply hex) is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen.
