  2. Stadimeter - Wikipedia

    en.wikipedia.org/wiki/Stadimeter

    A Mk 5 Mod 0 US Navy Stadimeter made in 1942 by Schick Inc. of Stamford CT. The hand held stadimeter was developed by Bradley Allen Fiske (1854–1942), an officer in the United States Navy. It was designed for gunnery purposes, but its first sea tests, conducted in 1895, showed that it was equally useful for fleet sailing and for navigation.

  3. Modulo - Wikipedia

    en.wikipedia.org/wiki/Modulo

    For example, the expression "5 mod 2" evaluates to 1, because 5 divided by 2 has a quotient of 2 and a remainder of 1, while "9 mod 3" would evaluate to 0, because 9 divided by 3 has a quotient of 3 and a remainder of 0. Although typically performed with a and n both being integers, many computing systems now allow other types of numeric operands.

  5. AGM-45 Shrike - Wikipedia

    en.wikipedia.org/wiki/AGM-45_Shrike

    The AGM-45A used the Rocketdyne Mk 39 Mod 0 (or apparently in some cases the Aerojet Mk 53 Mod 1) motor, while the AGM-45B used Aerojet Mk 78 Mod 0 which greatly increased the range of the missile. As for warheads, the Mk 5 Mod 0, Mk 86 Mod 0, and WAU-8/B could all be fitted to the AGM-45A and were all blast-fragmentation in nature.

  6. Modular arithmetic - Wikipedia

    en.wikipedia.org/wiki/Modular_arithmetic

    Adding 4 hours to 9 o'clock gives 1 o'clock, since 13 is congruent to 1 modulo 12. In mathematics, modular arithmetic is a system of arithmetic for integers, where numbers "wrap around" when reaching a certain value, called the modulus. The modern approach to modular arithmetic was developed by Carl Friedrich Gauss in his book Disquisitiones ...

    en.wikipedia.org/wiki/Proofs_of_Fermat's_little...

    Simplifications. Some of the proofs of Fermat's little theorem given below depend on two simplifications. The first is that we may assume that a is in the range 0 ≤ a ≤ p − 1. This is a simple consequence of the laws of modular arithmetic; we are simply saying that we may first reduce a modulo p.

  9. Mark 48 torpedo - Wikipedia

    en.wikipedia.org/wiki/Mark_48_torpedo

    The new version of the weapon, also known as Mk-48 Mod 5, was extensively tested and production started in 1985, with entry into service in 1988. From then on, various upgrades have been added to the torpedo. As of 2012 Mk-48 Mod 6 was in service; a Mod 7 version was test fired in 2008 in Exercise RIMPAC.
