    en.wikipedia.org/wiki/Self-phase_modulation

    Self-phase modulation (SPM) is a nonlinear optical effect of light–matter interaction. An ultrashort pulse of light, when travelling in a medium, will induce a varying refractive index of the medium due to the optical Kerr effect. [1]

  5. Atomic force microscopy - Wikipedia

    en.wikipedia.org/wiki/Atomic_force_microscopy

    Atomic force microscopy [1] (AFM) is a type of SPM, with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit. The information is gathered by "feeling" or "touching" the surface with a mechanical probe.

  6. Scanning probe microscopy - Wikipedia

    en.wikipedia.org/wiki/Scanning_probe_microscopy

    Scanning probe microscopy (SPM) is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. SPM was founded in 1981, with the invention of the scanning tunneling microscope , an instrument for imaging surfaces at the atomic level.

    While managing R&D projects for the Army and later at GE, Putnam noticed software staffing profiles followed the Rayleigh distribution. [2]Putnam used his observations about productivity levels to derive the software equation:

  8. Sum of perpetuities method - Wikipedia

    en.wikipedia.org/wiki/Sum_of_Perpetuities_Method

    SPM is derived from the compound interest formula via the present value of a perpetuity equation. The derivation requires the additional variables X {\displaystyle X} and R {\displaystyle R} , where X {\displaystyle X} is a company's retained earnings, and R {\displaystyle R} is a company's rate of return on equity.
