  2. Cryptogram - Wikipedia

    en.wikipedia.org/wiki/Cryptogram

    A cryptogram is a type of puzzle that consists of a short piece of encrypted text. [1] Generally the cipher used to encrypt the text is simple enough that the cryptogram can be solved by hand. Substitution ciphers where each letter is replaced by a different letter, number, or symbol are frequently used. To solve the puzzle, one must recover ...

    1.5 equals 384/256; 384 is stored, 256 is inferred because it is a Q8 number. If the Q number's base is to be maintained (n remains constant) the Q number math operations must keep the denominator constant. The following formulas show math operations on the general Q numbers and .

  5. Interquartile range - Wikipedia

    en.wikipedia.org/wiki/Interquartile_range

    Upper 1.5*IQR whisker = Q 3 + 1.5 * IQR = 9 + 3 = 12. (If there is no data point at 12, then the highest point less than 12.) Pattern of latter two bullet points: If there are no data points at the true quartiles, use data points slightly "inland" (closer to the median) from the actual quartiles. This means the 1.5*IQR whiskers can be uneven in ...

  6. Quantum cryptography - Wikipedia

    en.wikipedia.org/wiki/Quantum_cryptography

    Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. [1] [2] The best known example of quantum cryptography is quantum key distribution, which offers an information-theoretically secure solution to the key exchange problem.

  7. Q value (nuclear science) - Wikipedia

    en.wikipedia.org/wiki/Q_value_(nuclear_science)

    A reaction with a negative Q value is endothermic, i.e. requires a net energy input, since the kinetic energy of the final state is less than the kinetic energy of the initial state. [1] Observe that a chemical reaction is exothermic when it has a negative enthalpy of reaction, in contrast a positive Q value in a nuclear reaction.
