  2. Scale-free network - Wikipedia

    en.wikipedia.org/wiki/Scale-free_network

    A scale-free network is a network whose degree distribution follows a power law, at least asymptotically.That is, the fraction P(k) of nodes in the network having k connections to other nodes goes for large values of k as

  3. Paschen's law - Wikipedia

    en.wikipedia.org/wiki/Paschen's_law

    [2] [3] The curve he found of voltage versus the pressure-gap length product (right) is called Paschen's curve. He found an equation that fit these curves, which is now called Paschen's law. He found an equation that fit these curves, which is now called Paschen's law.

  4. Superformula - Wikipedia

    en.wikipedia.org/wiki/Superformula

    The superformula is a generalization of the superellipse and was proposed by Johan Gielis in 2003. [1] Gielis suggested that the formula can be used to describe many complex shapes and curves that are found in nature.

  5. Capability curve - Wikipedia

    en.wikipedia.org/wiki/Capability_curve

    Capability curve of an electrical generator describes the limits of the active and reactive power that the generator can provide. The curve represents a boundary of all operating points in the MW/MVAr plane; it is typically drawn with the real power on the horizontal axis, and, for the synchronous generator , resembles a letter D in shape, thus ...

  6. Open-circuit saturation curve - Wikipedia

    en.wikipedia.org/wiki/Open-circuit_saturation_curve

    The curve is typically plotted alongside the synchronous impedance curve. [ 1 ] At the low field, the permeable iron in the magnetic circuit of the generator is not saturated , therefore the reluctance almost entirely depends on the fixed contribution of the air gap , so the part of the curve that starts at the point of origin is a linear "air ...

  7. Linear system of divisors - Wikipedia

    en.wikipedia.org/wiki/Linear_system_of_divisors

    The characteristic linear system of a family of curves on an algebraic surface Y for a curve C in the family is a linear system formed by the curves in the family that are infinitely near C. [ 4 ] In modern terms, it is a subsystem of the linear system associated to the normal bundle to C ↪ Y {\displaystyle C\hookrightarrow Y} .

  9. Diode modelling - Wikipedia

    en.wikipedia.org/wiki/Diode_modelling

    The Shockley diode equation relates the diode current of a p-n junction diode to the diode voltage .This relationship is the diode I-V characteristic: = (), where is the saturation current or scale current of the diode (the magnitude of the current that flows for negative in excess of a few , typically 10 −12 A).
