  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. 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 ...

  4. 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]

  5. Fault model - Wikipedia

    en.wikipedia.org/wiki/Fault_model

    A fault model, falls under one of the following assumptions: single fault assumption: only one fault occur in a circuit. if we define k possible fault types in our fault model the circuit has n signal lines, by single fault assumption, the total number of single faults is k×n. multiple fault assumption: multiple faults may occur in a circuit.

  6. Electronic circuit simulation - Wikipedia

    en.wikipedia.org/wiki/Electronic_circuit_simulation

    Simulation software allows for the modeling of circuit operation and is an invaluable analysis tool. Due to its highly accurate modeling capability, many colleges and universities use this type of software for the teaching of electronics technician and electronics engineering programs. Electronics simulation software engages its users by ...

  7. 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.

  8. 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).

  9. Adaptive step size - Wikipedia

    en.wikipedia.org/wiki/Adaptive_step_size

    Let us now apply Euler's method again with a different step size to generate a second approximation to y(t n+1). We get a second solution, which we label with a (). Take the new step size to be one half of the original step size, and apply two steps of Euler's method. This second solution is presumably more accurate.
