  2. Little–Parks effect - Wikipedia

    en.wikipedia.org/wiki/Little–Parks_effect

    In condensed matter physics, the Little–Parks effect was discovered in 1962 by William A. Little and Ronald D. Parks in experiments with empty and thin-walled superconducting cylinders subjected to a parallel magnetic field. [1] It was one of the first experiments to indicate the importance of Cooper-pairing principle in BCS theory. [2]

  3. Skewness - Wikipedia

    en.wikipedia.org/wiki/Skewness

    In the older notion of nonparametric skew, defined as () /, where is the mean, is the median, and is the standard deviation, the skewness is defined in terms of this relationship: positive/right nonparametric skew means the mean is greater than (to the right of) the median, while negative/left nonparametric skew means the mean is less than (to ...

  4. Experiment - Wikipedia

    en.wikipedia.org/wiki/Experiment

    Experiments might be categorized according to a number of dimensions, depending upon professional norms and standards in different fields of study. In some disciplines (e.g., psychology or political science), a 'true experiment' is a method of social research in which there are two kinds of variables.

  5. Taylor column - Wikipedia

    en.wikipedia.org/wiki/Taylor_column

    Taylor column in fluid. Taylor columns have been rigorously studied. For Re<<1, Ek<<1, Ro<<1, the drag equation for a cylinder of radius, a, the following relation has been found.

  6. Bias (statistics) - Wikipedia

    en.wikipedia.org/wiki/Bias_(statistics)

    Detection bias occurs when a phenomenon is more likely to be observed for a particular set of study subjects. For instance, the syndemic involving obesity and diabetes may mean doctors are more likely to look for diabetes in obese patients than in thinner patients, leading to an inflation in diabetes among obese patients because of skewed detection efforts.

  7. Nonparametric skew - Wikipedia

    en.wikipedia.org/wiki/Nonparametric_skew

    In statistics and probability theory, the nonparametric skew is a statistic occasionally used with random variables that take real values. [ 1 ] [ 2 ] It is a measure of the skewness of a random variable's distribution —that is, the distribution's tendency to "lean" to one side or the other of the mean .

  8. Skew - Wikipedia

    en.wikipedia.org/wiki/Skew

    Skew lines, neither parallel nor intersecting. Skew normal distribution, a probability distribution; Skew field or division ring; Skew-Hermitian matrix; Skew lattice; Skew polygon, whose vertices do not lie on a plane; Infinite skew polyhedron; Skew-symmetric graph; Skew-symmetric matrix; Skew tableau, a generalization of Young tableaux

  9. Cylinder - Wikipedia

    en.wikipedia.org/wiki/Cylinder

    If the elements of the cylinder are perpendicular to the planes containing the bases, the cylinder is a right cylinder, otherwise it is called an oblique cylinder. If the bases are disks (regions whose boundary is a circle) the cylinder is called a circular cylinder. In some elementary treatments, a cylinder always means a circular cylinder. [2]
