  2. Five-qubit error correcting code - Wikipedia

    en.wikipedia.org/wiki/Five-qubit_error...

    In this code, 5 physical qubits are used to encode the logical qubit. [2] With X {\displaystyle X} and Z {\displaystyle Z} being Pauli matrices and I {\displaystyle I} the Identity matrix , this code's generators are X Z Z X I , I X Z Z X , X I X Z Z , Z X I X Z {\displaystyle \langle XZZXI,IXZZX,XIXZZ,ZXIXZ\rangle } .

  3. Error correction model - Wikipedia

    en.wikipedia.org/wiki/Error_correction_model

    Forecasts from such a model will still reflect cycles and seasonality that are present in the data. However, any information about long-run adjustments that the data in levels may contain is omitted and longer term forecasts will be unreliable. This led Sargan (1964) to develop the ECM methodology, which retains the level information. [4] [5]

  4. Errors-in-variables model - Wikipedia

    en.wikipedia.org/wiki/Errors-in-variables_model

    Linear errors-in-variables models were studied first, probably because linear models were so widely used and they are easier than non-linear ones. Unlike standard least squares regression (OLS), extending errors in variables regression (EiV) from the simple to the multivariable case is not straightforward, unless one treats all variables in the same way i.e. assume equal reliability.

  5. Inertial measurement unit - Wikipedia

    en.wikipedia.org/wiki/Inertial_measurement_unit

    For example, if an IMU installed in an aeroplane moving along a certain direction vector were to measure a plane's acceleration as 5 m/s 2 for 1 second, then after that 1 second the guidance computer would deduce that the plane must be traveling at 5 m/s and must be 2.5 m from its initial position (assuming v 0 =0 and known starting position ...

  6. Error correction code - Wikipedia

    en.wikipedia.org/wiki/Error_correction_code

    If the number of errors within a code word exceeds the error-correcting code's capability, it fails to recover the original code word. Interleaving alleviates this problem by shuffling source symbols across several code words, thereby creating a more uniform distribution of errors. [ 21 ]

  7. Miniature inertial measurement unit - Wikipedia

    en.wikipedia.org/wiki/Miniature_inertial...

    Miniature inertial measurement unit (MIMU) is an inertial measurement unit (IMU) developed and built by Honeywell International [2] to control and stabilize spacecraft during mission operations. MIMUs can also be configured to perform as an inertial reference unit (IRU).

  8. Interval arithmetic - Wikipedia

    en.wikipedia.org/wiki/Interval_arithmetic

    As is the case with computing with real numbers, computing with complex numbers involves uncertain data. So, given the fact that an interval number is a real closed interval and a complex number is an ordered pair of real numbers , there is no reason to limit the application of interval arithmetic to the measure of uncertainties in computations ...

  9. Transfer alignment - Wikipedia

    en.wikipedia.org/wiki/Transfer_alignment

    Different factors will affect the accuracy of the transfer alignment, such as reference information delay, mounting error, sensor measurement error, lever-arm effect [2] and flexure of the carrier body.
