  2. Gloss (optics) - Wikipedia

    en.wikipedia.org/wiki/Gloss_(optics)

    For his research he used a glossmeter with a specular angle of 45° as did most of the first photoelectric methods of that type, later studies however by Hunter and D. B. Judd in 1939, [5] on a larger number of painted samples, concluded that the 60 degree geometry was the best angle to use so as to provide the closest correlation to a visual ...

  3. Technique for human error-rate prediction - Wikipedia

    en.wikipedia.org/wiki/Technique_for_human_error...

    The degree to which each high-level task is broken down into lower-level tasks is dependent on the availability of HEPs for the successive individual branches. The HEPs may be derived from a range of sources such as the THERP database; simulation data; historical accident data, and expert judgment.

  4. Graph factorization - Wikipedia

    en.wikipedia.org/wiki/Graph_factorization

    A perfect pair from a 1-factorization is a pair of 1-factors whose union induces a Hamiltonian cycle. A perfect 1-factorization (P1F) of a graph is a 1-factorization having the property that every pair of 1-factors is a perfect pair. A perfect 1-factorization should not be confused with a perfect matching (also called a 1-factor).

    They are sometimes collectively known as the shell. The term rime covers the nucleus plus coda. In the one-syllable English word cat, the nucleus is a (the sound that can be shouted or sung on its own), the onset c, the coda t, and the rime at. This syllable can be abstracted as a consonant-vowel-consonant syllable, abbreviated CVC.

    Aphakia correction: High degree hypermetropia due to absence of lens (aphakia) is best corrected using intraocular lens implantation. [ citation needed ] Refractive lens exchange (RLE): A variation of cataract surgery where the natural crystalline lens is replaced with an artificial intraocular lens ; the difference is the existence of abnormal ...

    The data from the experiments showed a high degree of correlation between the four factors, which were consistent with a similar study performed several years prior. In that study, an increase in muscle fiber conduction velocity was observed when there was a higher level of voluntary muscle contraction, which agrees with the gradual recruitment ...

  8. 4-polytope - Wikipedia

    en.wikipedia.org/wiki/4-polytope

    Just as a 3D shape can be projected onto a flat sheet, so a 4-D shape can be projected onto 3-space or even onto a flat sheet. One common projection is a Schlegel diagram which uses stereographic projection of points on the surface of a 3-sphere into three dimensions, connected by straight edges, faces, and cells drawn in 3-space.

  9. Hilbert series and Hilbert polynomial - Wikipedia

    The typical situations where these notions are used are the following: The quotient by a homogeneous ideal of a multivariate polynomial ring, graded by the total degree. The quotient by an ideal of a multivariate polynomial ring, filtered by the total degree. The filtration of a local ring by the powers of its maximal ideal.
