    en.wikipedia.org/wiki/Level_(logarithmic_quantity)

    A field level (or root-power level) is a logarithmic quantity used to measure quantities of which the square is typically proportional to power (for instance, the square of voltage is proportional to power by the inverse of the conductor's resistance), etc., with commonly used units neper (Np) or decibel (dB).

    NCSA is now headquartered within its own building directly north of the Siebel Center for Computer Science, on the site of a former baseball field, Illini Field. NCSA's supercomputers are at the National Petascale Computing Facility. [2] [19] The latest supercomputing system at NCSA today is the DeltaAI, funded by the National Science ...

    en.wikipedia.org/.../NCSA_Open_Source_License

    The University of Illinois/NCSA Open Source License is a permissive free software license, based on the MIT/X11 license and the 3-clause BSD license. By combining parts of these two licenses, it attempts to be clearer and more concise than either. [3] The license is the result of efforts by a University of Illinois committee set up in 2001.

    en.wikipedia.org/wiki/Hanle_effect

    The zero-field Hanle level crossings involve magnetic fields, in which the states which are degenerate at zero magnetic field are split due to the Zeeman effect. There is also the closely analogous zero-field Stark level crossings with electric fields, in which the states which are degenerate at zero electric field are split due to the Stark ...

  9. Scientific visualization - Wikipedia

    en.wikipedia.org/wiki/Scientific_visualization

    The primary methods for visualizing two-dimensional (2D) scalar fields are color mapping and drawing contour lines. 2D vector fields are visualized using glyphs and streamlines or line integral convolution methods. 2D tensor fields are often resolved to a vector field by using one of the two eigenvectors to represent the tensor each point in ...
