  2. Rule of three (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Rule_of_three_(aeronautics)

    In aviation, the rule of three or "3:1 rule of descent" is a rule of thumb that 3 nautical miles (5.6 km) of travel should be allowed for every 1,000 feet (300 m) of descent. [1] [2] For example, a descent from flight level 350 would require approximately 35x3=105 nautical miles. This would have to be adjusted for headwind or tailwind, [1] and ...

  3. Simpson's rules (ship stability) - Wikipedia

    en.wikipedia.org/wiki/Simpson's_rules_(ship...

    For instance, in the latter, Simpson's 3rd rule is used to find the volume between two co-ordinates. To calculate the entire area / volume, Simpson's first rule is used. [7] Simpson's rules are used by a ship's officers to check that the area under the ship's GZ curve complies with IMO stability criteria.

  4. 1 in 60 rule - Wikipedia

    en.wikipedia.org/wiki/1_in_60_rule

    For a 1 degree shift at 1 NM, there are about 100 feet of offset. This becomes very useful for estimating or correcting vertical speed settings and flight path angles (FPA) during climb, descent, or approaches. If a gradient in % is required, the numbers work out with the same rule: 1% over 1 NM ≈ 60'

  5. Microphone practice - Wikipedia

    en.wikipedia.org/wiki/Microphone_practice

    In close miking, a microphone is placed relatively close to an instrument or sound source, within three to twelve inches, producing a dry or non-reverberant sound. [1] This serves to reduce extraneous noise, including room reverberation and is commonly used when attempting to record a number of separate instruments while keeping the signals ...

  6. Dynamic range - Wikipedia

    en.wikipedia.org/wiki/Dynamic_range

    Dynamic range (abbreviated DR, DNR, [1] or DYR [2]) is the ratio between the largest and smallest measurable values of a specific quantity. It is often used in the context of signals, like sound and light.

  7. Coordinate descent - Wikipedia

    en.wikipedia.org/wiki/Coordinate_descent

    Coordinate descent is an optimization algorithm that successively minimizes along coordinate directions to find the minimum of a function.At each iteration, the algorithm determines a coordinate or coordinate block via a coordinate selection rule, then exactly or inexactly minimizes over the corresponding coordinate hyperplane while fixing all other coordinates or coordinate blocks.

  8. Signal-to-noise ratio - Wikipedia

    en.wikipedia.org/wiki/Signal-to-noise_ratio

    The OSNR is the ratio between the signal power and the noise power in a given bandwidth. Most commonly a reference bandwidth of 0.1 nm is used. This bandwidth is independent of the modulation format, the frequency and the receiver. For instance an OSNR of 20 dB/0.1 nm could be given, even the signal of 40 GBit DPSK would not fit in this bandwidth.

  9. Maximal information coefficient - Wikipedia

    en.wikipedia.org/wiki/Maximal_information...

    The MIC belongs to the maximal information-based nonparametric exploration (MINE) class of statistics. [1] In a simulation study, MIC outperformed some selected low power tests, [ 1 ] however concerns have been raised regarding reduced statistical power in detecting some associations in settings with low sample size when compared to powerful ...
