  2. Rotation model of learning - Wikipedia

    en.wikipedia.org/wiki/Rotation_Model_of_Learning

    Station rotation: a rotation model in which for a given course or the subject, the student rotates on a fixed schedule or at teacher's discretion one online learning station to another which might be activities such as small group instruction, group projects, and individual tutoring. It differs from individual-rotation model.

  3. Bishop Ring (habitat) - Wikipedia

    en.wikipedia.org/wiki/Bishop_Ring_(habitat)

    A Bishop Ring [1] is a type of hypothetical rotating wheel space station originally proposed in 1997 by Forrest Bishop of the Institute of Atomic-Scale Engineering. [2] The concept is a smaller scale version of the Banks Orbital , which itself is a smaller version of the Niven ring . [ 3 ]

  4. International Terrestrial Reference System and Frame

    en.wikipedia.org/wiki/International_Terrestrial...

    First solution that combines unconstrained space geodesy solutions free from any tectonic plate motion model. [4] From this version onwards, the motion of the tectonic plate is represented in the solution for each station as a velocity vector. Previous ITRFs only continued the initial positions, using a motion model to fill in the velocity ...

  5. Geneva drive - Wikipedia

    en.wikipedia.org/wiki/Geneva_drive

    The Geneva drive or Geneva mechanism is a gear mechanism that translates a continuous rotation movement into intermittent rotary motion. The rotating drive wheel is usually equipped with a pin that reaches into a slot located in the other wheel (driven wheel) that advances it by one step at a time. The drive wheel also has an elevated circular ...

  6. Rotation matrix - Wikipedia

    en.wikipedia.org/wiki/Rotation_matrix

    Every rotation in three dimensions is defined by its axis (a vector along this axis is unchanged by the rotation), and its angle — the amount of rotation about that axis (Euler rotation theorem). There are several methods to compute the axis and angle from a rotation matrix (see also axis–angle representation ).
