  2. Current injection technique - Wikipedia

    en.wikipedia.org/wiki/Current_injection_technique

    In summary, current injection technique makes it possible to use devices with low forward voltage drop for high frequency applications. This also imply cheaper cost of devices as less processing steps are required during the manufacturing stages where the need of carrier lifetime control techniques are reduced.

  3. Lanczos resampling - Wikipedia

    en.wikipedia.org/wiki/Lanczos_resampling

    The sum of these translated and scaled kernels is then evaluated at the desired points. Lanczos resampling is typically used to increase the sampling rate of a digital signal, or to shift it by a fraction of the sampling interval. It is often used also for multivariate interpolation, for example to resize or rotate a digital image. It has been ...

  4. Particle swarm optimization - Wikipedia

    en.wikipedia.org/wiki/Particle_swarm_optimization

    A particle swarm searching for the global minimum of a function. In computational science, particle swarm optimization (PSO) [1] is a computational method that optimizes a problem by iteratively trying to improve a candidate solution with regard to a given measure of quality.

    Likewise, one can say that set "has fewer than or the same number of elements" as set , if there is an injection from to ; one can also say that set "has fewer than the number of elements" in set , if there is an injection from to , but not a bijection between and .

  6. Inclusion map - Wikipedia

    en.wikipedia.org/wiki/Inclusion_map

    This and other analogous injective functions [3] from substructures are sometimes called natural injections. Given any morphism f {\displaystyle f} between objects X {\displaystyle X} and Y {\displaystyle Y} , if there is an inclusion map ι : A → X {\displaystyle \iota :A\to X} into the domain X {\displaystyle X} , then one can form the ...

  7. Shooting method - Wikipedia

    en.wikipedia.org/wiki/Shooting_method

    In numerical analysis, the shooting method is a method for solving a boundary value problem by reducing it to an initial value problem.It involves finding solutions to the initial value problem for different initial conditions until one finds the solution that also satisfies the boundary conditions of the boundary value problem.

  8. Fault injection - Wikipedia

    en.wikipedia.org/wiki/Fault_injection

    These parameters create the fault space realm. The fault space realm will increase exponentially by increasing system complexity. Therefore, the traditional fault injection method will not be applicable to use in the modern cyber-physical systems, because they will be so slow, and they will find a small number of faults (less fault coverage).

  9. Automatic lubrication system - Wikipedia

    en.wikipedia.org/wiki/Automatic_lubrication_system

    When the system is started, a pump increases the pressure of lubricant throughout the system to a set point. A pressure switch signals the control system that lubricant has been applied at all the lubricant distribution points have been reached. The pump stops, pressure is vented from the system and the lubricant is directed back to the pump ...
