  2. Window (geology) - Wikipedia

    en.wikipedia.org/wiki/Window_(geology)

    A tectonic window, or fenster (lit. "window" in German), is a geologic structure formed by erosion or normal faulting on a thrust system. In such a system the rock mass ( hanging wall block ) that has been transported by movement along the thrust is called a nappe .

  3. Wood warping - Wikipedia

    en.wikipedia.org/wiki/Wood_warping

    The types of wood warping include: bow: a warp along the length of the face of the wood; crook: a warp along the length of the edge of the wood; kink: a localized crook, often due to a knot; cup: a warp across the width of the face, in which the edges are higher or lower than the center of the wood

  4. Dynamic time warping - Wikipedia

    en.wikipedia.org/wiki/Dynamic_time_warping

    The windows that classical DTW uses to constrain alignments introduce a step function. Any warping of the path is allowed within the window and none beyond it. In contrast, ADTW employs an additive penalty that is incurred each time that the path is warped. Any amount of warping is allowed, but each warping action incurs a direct penalty.

  5. Randall–Sundrum model - Wikipedia

    en.wikipedia.org/wiki/Randall–Sundrum_model

    The RS1 model attempts to address the hierarchy problem. The warping of the extra dimension is analogous to the warping of spacetime in the vicinity of a massive object, such as a black hole. This warping, or red-shifting, generates a large ratio of energy scales, so that the natural energy scale at one end of the extra dimension is much larger ...

  6. Distortion (optics) - Wikipedia

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

    In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...

  7. Image geometry correction - Wikipedia

    en.wikipedia.org/wiki/Image_geometry_correction

    The simplest application of image geometry correction is a specific case known as keystone distortion correction derived from Keystone effect.Keystone distortion gets its name from the symmetric trapezoidal distortion resulting from misaligned projector placement in the vertical dimension (although the term is generally applied to the non-symmetric quadrilateral shape that occurs from an off ...

  9. Broken windows theory - Wikipedia

    en.wikipedia.org/wiki/Broken_windows_theory

    A successful strategy for preventing vandalism, according to the book's authors, is to address the problems when they are small. Repair the broken windows within a short time, say, a day or a week, and the tendency is that vandals are much less likely to break more windows or do further damage.
