Contact between a sphere and an elastic half-space and one-dimensional replaced model. Some contact problems can be solved with the Method of Dimensionality Reduction (MDR). In this method, the initial three-dimensional system is replaced with a contact of a body with a linear elastic or viscoelastic foundation (see fig.).

Microsoft Paint. Microsoft Paint (commonly known as MS Paint or Paint for short) is a simple raster graphics editor that has been included with all versions of Microsoft Windows. The program opens, modifies and saves image files in Windows bitmap (BMP), JPEG, GIF, PNG, and single-page TIFF formats. The program can be in color mode or two-color ...
Contact geometry. The standard contact structure on R3. Each point in R3 has a plane associated to it by the contact structure, in this case as the kernel of the one-form dz − y dx. These planes appear to twist along the y -axis. It is not integrable, as can be verified by drawing an infinitesimal square in the x - y plane, and follow the ...
Cell junction. Cell junctions[ 1] or junctional complexes are a class of cellular structures consisting of multiprotein complexes that provide contact or adhesion between neighboring cells or between a cell and the extracellular matrix in animals. [ 2] They also maintain the paracellular barrier of epithelia and control paracellular transport.
Point contacts. Point contacts may refer to: Contact breaker, a type of electrical switch. Point contact diode, a type of semiconductor diode. Point of contact, a person serving as the focal point of information concerning an activity. Point-contact transistor, the first type of solid-state electronic transistor ever constructed, in 1947.
The point-contact transistor was the first type of transistor to be successfully demonstrated. It was developed by research scientists John Bardeen and Walter Brattain at Bell Laboratories in December 1947. [1] [2] They worked in a group led by physicist William Shockley. The group had been working together on experiments and theories of ...
