  2. lambda-connectedness - Wikipedia

    en.wikipedia.org/wiki/Lambda-connectedness

    The lambda-connected segmentation is a region-growing segmentation method in general. It can also be made for split-and-merge segmentation. [ 4 ] Its time complexity also reaches the optimum at O ( n l o g n ) {\displaystyle O(nlogn)} where n {\displaystyle n} is the number of pixels in the image.

  3. Hubble's law - Wikipedia

    en.wikipedia.org/wiki/Hubble's_law

    The redshift z is often described as a redshift velocity, which is the recessional velocity that would produce the same redshift if it were caused by a linear Doppler effect (which, however, is not the case, as the velocities involved are too large to use a non-relativistic formula for Doppler shift).

  4. Reed–Solomon error correction - Wikipedia

    en.wikipedia.org/wiki/Reed–Solomon_error...

    Reed & Solomon (1960) described a theoretical decoder that corrected errors by finding the most popular message polynomial. The decoder only knows the set of values to and which encoding method was used to generate the codeword's sequence of values. The original message, the polynomial, and any errors are unknown.

  5. Redshift - Wikipedia

    en.wikipedia.org/wiki/Redshift

    The effect is sometimes called the "Doppler–Fizeau effect". In 1868, British astronomer William Huggins was the first to determine the velocity of a star moving away from the Earth by the method. [5] In 1871, optical redshift was confirmed when the phenomenon was observed in Fraunhofer lines, using solar rotation, about 0.1 Å in the red. [6]

  6. Fixed-point combinator - Wikipedia

    en.wikipedia.org/wiki/Fixed-point_combinator

    A class is used to contain the fix function, called fixer. The function to be fixed is contained in a class that inherits from fixer. The fix function accesses the function to be fixed as a virtual function. As for the strict functional definition, fix is explicitly given an extra parameter x, which means that lazy evaluation is not needed.

  7. Lambda calculus - Wikipedia

    so that FIX G = G (FIX G) = (λn.(1, if n = 0; else n × ((FIX G) (n−1)))) Given a lambda term with first argument representing recursive call (e.g. G here), the fixed-point combinator FIX will return a self-replicating lambda expression representing the recursive function (here, F). The function does not need to be explicitly passed to ...

  8. Redshift (renderer) - Wikipedia

    en.wikipedia.org/wiki/Redshift_(renderer)

    According to the developer's claim, Redshift is the first 3D renderer with full GPU acceleration on the market. It was initially released in 2014 by Redshift Rendering Technologies Inc. [ 2 ] [ 3 ] In 2017 Redshift experimented with a virtual reality input user interface, initially tailored for architects.

  9. Connection (vector bundle) - Wikipedia

    en.wikipedia.org/wiki/Connection_(vector_bundle)

    Let M be a differentiable manifold, such as Euclidean space.A vector-valued function can be viewed as a section of the trivial vector bundle. One may consider a section of a general differentiable vector bundle, and it is therefore natural to ask if it is possible to differentiate a section, as a generalization of how one differentiates a function on M.
