  2. Stability derivatives - Wikipedia

    "X" or "x" axis runs from back to front along the body, called the Roll Axis. "Y" or "y" axis runs left to right along the wing, called the Pitch Axis. "Z" or "z" runs from top to bottom, called the Yaw Axis. Two slightly different alignments of these axes are used depending on the situation: "body-fixed axes", and "stability axes".

  4. Z-pinch - Wikipedia

    en.wikipedia.org/wiki/Z-pinch

    In fusion power research, the Z-pinch (zeta pinch) is a type of plasma confinement system that uses an electric current in the plasma to generate a magnetic field that compresses it (see pinch). These systems were originally referred to simply as pinch or Bennett pinch (after Willard Harrison Bennett ), but the introduction of the θ-pinch ...

  5. Axes conventions - Wikipedia

    en.wikipedia.org/wiki/Axes_conventions

    For positive y- and z-axis, we have to face two different conventions: In case of land vehicles like cars, tanks etc., which use the ENU-system (East-North-Up) as external reference (World frame), the vehicle's (body's) positive y- or pitch axis always points to its left, and the positive z- or yaw axis always points up. World frame's origin is ...

  6. Directional stability - Wikipedia

    en.wikipedia.org/wiki/Directional_stability

    Directional stability is stability of a moving body or vehicle about an axis which is perpendicular to its direction of motion. Stability of a vehicle concerns itself with the tendency of a vehicle to return to its original direction in relation to the oncoming medium (water, air, road surface, etc.) when disturbed (rotated) away from that original direction.

  7. 2.5D (machining) - Wikipedia

    en.wikipedia.org/wiki/2.5D_(machining)

    A 2.5D machine, also called a two-and-a-half-axis mill, possesses the capability to translate in all three axes but can perform the cutting operation only in two of the three axes at a time due to hardware or software limitations, or a machine that has a solenoid instead of a true, linear Z axis. A typical example involves an XY table that ...

  9. H-infinity methods in control theory - Wikipedia

    en.wikipedia.org/wiki/H-infinity_methods_in...

    The phrase H ∞ control comes from the name of the mathematical space over which the optimization takes place: H ∞ is the Hardy space of matrix-valued functions that are analytic and bounded in the open right-half of the complex plane defined by Re(s) > 0; the H ∞ norm is the supremum singular value of the matrix over that space.
