In mean field theory, the mean field appearing in the single-site problem is a time-independent scalar or vector quantity.

For instance, DMFT can be applied...

In meantone systems, there are two different semitones.

The chromatic semitone is usually smal...

Cam followers come in a vast array of different configurations, however the most defining characteristic is how the cam follower mounts to its mating part; s...

In mechanical engineering, a compliant mechanism is a flexible mechanism that achieves force and motion transmission through elastic body deformation. It gains some or all of its motion from the relative flexibility of its members rather than from rigid-body joints alone. These may be monolithic (single-piece) or joint...

In mechanical engineering, a compression seal fitting, also known as a sealing gland, is intended to seal some type of element (probe, wire, conductor, pipe, tube, fiber optic cable, etc.) when the element must pass through a pressure or environmental boundary. A compression seal fitting may serve several purposes: It ...

In mechanical engineering, a crosshead is a mechanical joint used as part of the slider-crank linkages of long reciprocating engines (either internal combustion or steam) and reciprocating compressors to eliminate sideways force on the piston. Also, the crosshead enables the connecting rod to freely move outside the cy...

In mechanical engineering, a diaphragm seal is a flexible membrane that seals and isolates an enclosure. The flexible nature of this seal allows pressure effects to cross the barrier but not the material being contained. Common uses for diaphragm seals are to protect pressure sensors from the fluid whose pressure is be...

In mechanical engineering, a docking sleeve or mounting boss is a tube or enclosure used to couple two mechanical components together, or for chilling, or to retain two components together; this permits two equally sized appendages to be connected via insertion and fixing within the construction. Docking sleeves may be...

In mechanical engineering, a face seal is a seal in which the sealing surfaces are normal to the axis of the seal. Face seals are typically used in static applications and are used to prevent leakage in the radial direction with respect to the axis of the seal. Face seals are often located in a groove or cavity on a fl...
