  2. Hadamard factorization theorem - Wikipedia

    en.wikipedia.org/wiki/Hadamard_factorization_theorem

    With Hadamard factorization we can prove some special cases of Picard's little theorem. Theorem: [ 4 ] If f {\displaystyle f} is entire, nonconstant, and has finite order, then it assumes either the whole complex plane or the plane minus a single point.

  3. Principal component analysis - Wikipedia

    en.wikipedia.org/wiki/Principal_component_analysis

    Principal component analysis (PCA) is a linear dimensionality reduction technique with applications in exploratory data analysis, visualization and data preprocessing.. The data is linearly transformed onto a new coordinate system such that the directions (principal components) capturing the largest variation in the data can be easily identified.

  4. China Fusion Engineering Test Reactor - Wikipedia

    As such, to tackle the 19 key system problems posed by the CFETR, individual teams have been formed to tackle each issue in isolation. [8] This initiative is spearheaded by the Comprehensive Research Facility for Fusion Technology (CRAFT) and their team of 300 scientists, engineers and researchers in China in an attempt to resolve these ...

    en.wikipedia.org/wiki/Algorithm

    Flowchart of using successive subtractions to find the greatest common divisor of number r and s. In mathematics and computer science, an algorithm (/ ˈ æ l ɡ ə r ɪ ð əm / ⓘ) is a finite sequence of mathematically rigorous instructions, typically used to solve a class of specific problems or to perform a computation. [1]

  6. Stress–strain curve - Wikipedia

    en.wikipedia.org/wiki/Stress–strain_curve

    In engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strain.It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing).

  7. ITER - Wikipedia

    en.wikipedia.org/wiki/ITER

    [29] [30] Regardless of the final cost, ITER has already been described as the most expensive science experiment of all time, [31] the most complicated engineering project in human history, [32] and one of the most ambitious human collaborations since the development of the International Space Station (€100 billion or $150 billion budget) and ...

  8. Viscosity - Wikipedia

    en.wikipedia.org/wiki/Viscosity

    The proportionality factor is the dynamic viscosity of the fluid, often simply referred to as the viscosity. It is denoted by the Greek letter mu ( μ ). The dynamic viscosity has the dimensions ( m a s s / l e n g t h ) / t i m e {\displaystyle \mathrm {(mass/length)/time} } , therefore resulting in the SI units and the derived units :

  9. Big O notation - Wikipedia

    en.wikipedia.org/wiki/Big_O_notation

    Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. Big O is a member of a family of notations invented by German mathematicians Paul Bachmann, [1] Edmund Landau, [2] and others, collectively called Bachmann–Landau notation or asymptotic notation.
