  2. Direct–inverse alignment - Wikipedia

    en.wikipedia.org/wiki/Directinverse_alignment

    As can be seen, the only difference between these two verbs is the directinverse opposition, rather than case markers (or word order, when distinct nominals are used). An inverse verb is not equivalent to a passive verb. There is a separate passivity marker, denoted in literature as "indefinite person (X)", ranked in topicality hierarchy ...

  3. Proportionality (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Proportionality_(mathematics)

    With inverse proportion, an increase in one variable is associated with a decrease in the other. For instance, in travel, a constant speed dictates a direct proportion between distance and time travelled; in contrast, for a given distance (the constant), the time of travel is inversely proportional to speed: s × t = d.

  4. Spin Hall effect - Wikipedia

    en.wikipedia.org/wiki/Spin_Hall_effect

    The direct and inverse spin Hall effect can be monitored by optical means. The spin accumulation induces circular polarization of the emitted light, as well as the Faraday (or Kerr) polarization rotation of the transmitted (or reflected) light. Observing the polarization of emitted light allows the spin Hall effect to be observed.

  5. Symmetrical components - Wikipedia

    en.wikipedia.org/wiki/Symmetrical_components

    As shown in the figure to the above right, the three sets of symmetrical components (positive, negative, and zero sequence) add up to create the system of three unbalanced phases as pictured in the bottom of the diagram. The imbalance between phases arises because of the difference in magnitude and phase shift between the sets of vectors.

  6. Inverse kinematics - Wikipedia

    en.wikipedia.org/wiki/Inverse_kinematics

    Forward vs. inverse kinematics. In computer animation and robotics, inverse kinematics is the mathematical process of calculating the variable joint parameters needed to place the end of a kinematic chain, such as a robot manipulator or animation character's skeleton, in a given position and orientation relative to the start of the chain.

  7. Vincenty's formulae - Wikipedia

    Difference in longitude of the points on the auxiliary sphere; α 1, α 2: forward azimuths at the points; α: forward azimuth of the geodesic at the equator, if it were extended that far; s: ellipsoidal distance between the two points; σ: angular separation between points: σ 1: angular separation between the point and the equator: σ m

  8. Rashba–Edelstein effect - Wikipedia

    en.wikipedia.org/wiki/Rashba–Edelstein_effect

    As for the direct effect, this analysis has been carried out for the inverse Edelstein effect because in this case only two energy branches are present. For what concerns the inverse Rashba–Edelstein effect, the process is very similar despite the presence of four energy branches, with spin-momentum locking, in the dispersion relation and two ...

  9. Inverted repeat - Wikipedia

    en.wikipedia.org/wiki/Inverted_repeat

    Thus, recombination occurring at a pair of inverted sites will invert the DNA sequence between the two sites. [10] Very stable chromosomes have been observed with comparatively fewer numbers of inverted repeats than direct repeats, suggesting a relationship between chromosome stability and the number of repeats.
