  2. Frontogenesis - Wikipedia

    en.wikipedia.org/wiki/Frontogenesis

    Horizontal deformation in mid-latitude cyclones concentrates temperature gradients—cold air from the poles and warm air from the equator.. Horizontal shear has two effects on an air parcel; it tends to rotate the parcel (think of placing a wheel at a point in space and as the wind blows, the wheel rotates) and deform the parcel through stretching and shrinking.

  3. Product line extension - Wikipedia

    en.wikipedia.org/wiki/Product_line_extension

    The company can extend its product line down-market stretch, up-market stretch, or both ways. Product line extensions are a process where companies with an established brand alter the factors of a product or products to satisfy a refined segment in the market. [1] There are two types of product line extensions, horizontal and vertical.

  4. English wheel - Wikipedia

    en.wikipedia.org/wiki/English_wheel

    This is most easily done using Eckold shrinking and stretching, but can be done using heat shrinking or cold shrinking, by tucking and beating the tucked metal into itself, or by using a cold shrinking hammer and dolly. Stretching or shrinking the flange requires a correct profile hammer and dolly. The hammer and dolly must match the desired ...

  5. Scaling (geometry) - Wikipedia

    en.wikipedia.org/wiki/Scaling_(geometry)

    Each iteration of the Sierpinski triangle contains triangles related to the next iteration by a scale factor of 1/2. In affine geometry, uniform scaling (or isotropic scaling [1]) is a linear transformation that enlarges (increases) or shrinks (diminishes) objects by a scale factor that is the same in all directions (isotropically).

  6. Shear mapping - Wikipedia

    en.wikipedia.org/wiki/Shear_mapping

    An example is the linear map that takes any point with coordinates (,) to the point (+,). In this case, the displacement is horizontal by a factor of 2 where the fixed line is the x-axis, and the signed distance is the y-coordinate. Note that points on opposite sides of the reference line are displaced in opposite directions.

    Researchers have produced conflicting results when it comes to the best pre-workout stretch. For example, a well-cited August 2003 study showed evidence of static stretching for warm-ups worsening ...

  8. Lagrangian coherent structure - Wikipedia

    en.wikipedia.org/wiki/Lagrangian_coherent_structure

    As such, parabolic LCSs are composed of shrink lines and stretch lines that represent geodesics of the Lorentzian metric tensor. In contrast to hyperbolic LCSs, however, parabolic LCSs satisfy more robust boundary conditions: they remain stationary curves of the material-line-averaged shear functional even under variations to their endpoints.

    Soaking the shrunken clothes in a mixture of warm water and conditioner can help them stretch out, one user writes. The warm water relaxes the fibers while the conditioner softens and lubricates ...
