  2. Linear transformation in rotating electrical machines - Wikipedia

    en.wikipedia.org/wiki/Linear_transformation_in...

    Transformation of three phase electrical quantities to two phase quantities is a usual practice to simplify analysis of three phase electrical circuits. Polyphase a.c machines can be represented by an equivalent two phase model provided the rotating polyphases winding in rotor and the stationary polyphase windings in stator can be expressed in a fictitious two axes coils.

  3. Alpha–beta transformation - Wikipedia

    en.wikipedia.org/wiki/Alpha–beta_transformation

    The transformation can be thought of as the projection of the three phase quantities (voltages or currents) onto two stationary axes, the alpha axis and the beta axis. However, no information is lost if the system is balanced, as the equation I a + I b + I c = 0 {\displaystyle I_{a}+I_{b}+I_{c}=0} is equivalent to the equation for I γ ...

  4. Angle of attack - Wikipedia

    en.wikipedia.org/wiki/Angle_of_attack

    Angle of attack of an airfoil. In fluid dynamics, angle of attack (AOA, α, or ) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving. [1]

  5. Alpha–beta pruning - Wikipedia

    en.wikipedia.org/wiki/Alpha–beta_pruning

    Alpha–beta pruning is a search algorithm that seeks to decrease the number of nodes that are evaluated by the minimax algorithm in its search tree. It is an adversarial search algorithm used commonly for machine playing of two-player combinatorial games ( Tic-tac-toe , Chess , Connect 4 , etc.).

  7. Stringer (slag) - Wikipedia

    en.wikipedia.org/wiki/Stringer_(slag)

    Stringers are filaments of slag left in wrought iron after the production process. In their correct proportions their presence is beneficial, as they help to control the ductility of the finished product, but when the proportion of slag is too high, or when the filaments run at right angles to the direction of tension, they can cause weakness.

  8. Video matting - Wikipedia

    en.wikipedia.org/wiki/Video_matting

    Video matting is a technique for separating the video into two or more layers, usually foreground and background, and generating alpha mattes which determine blending of the layers. The technique is very popular in video editing because it allows to substitute the background, or process the layers individually.

  9. Generation Z - Wikipedia

    en.wikipedia.org/wiki/Generation_Z

    Generation Z (often shortened to Gen Z), also known as Zoomers, [1] [2] [3] is the demographic cohort succeeding Millennials and preceding Generation Alpha.Researchers and popular media use the mid-to-late 1990s as starting birth years and the early 2010s as ending birth years, with the generation most frequently being defined as people born from 1997 to 2012.
