  2. Contact resistance - Wikipedia

    en.wikipedia.org/wiki/Contact_resistance

    Contact resistance values are typically small (in the microohm to milliohm range). Contact resistance can cause significant voltage drops and heating in circuits with high current. Because contact resistance adds to the intrinsic resistance of the conductors, it can cause significant measurement errors when exact resistance values are needed.

    Contact mechanics is the study of the deformation of solids that touch each other at one or ... Friction drive – Mechanical power transmission by friction between ...

  4. Contact tracing - Wikipedia

    en.wikipedia.org/wiki/Contact_tracing

    In public health, contact tracing is the process of identifying people who may have been exposed to an infected person ("contacts") and subsequent collection of further data to assess transmission. [ 1 ] [ 2 ] By tracing the contacts of infected individuals, testing them for infection, and isolating or treating the infected, this public health ...

  5. Contact (1997 American film) - Wikipedia

    en.wikipedia.org/wiki/Contact_(1997_American_film)

    Contact was released on LaserDisc, VHS and the (then new) DVD format in December 1997. Among the special features are three audio commentaries: by director Zemeckis and producer Starkey, by visual effects supervisors Ken Ralston and Stephen Rosenbaum, and by star Jodie Foster. [34] Contact was released on Blu-ray Disc on October 6, 2009 ...

  6. Transfer length method - Wikipedia

    en.wikipedia.org/wiki/Transfer_length_method

    The Transfer Length Method or the "Transmission Line Model" (both abbreviated as TLM) is a technique used in semiconductor physics and engineering to determine the specific contact resistivity between a metal and a semiconductor.

  7. Frictional contact mechanics - Wikipedia

    en.wikipedia.org/wiki/Frictional_contact_mechanics

    Finally there are the processes at the contact interface: compression and adhesion in the direction perpendicular to the interface, and friction and micro-slip in the tangential directions. The last aspect is the primary concern of contact mechanics. It is described in terms of so-called contact conditions. For the direction perpendicular to ...

  8. Thermal contact conductance - Wikipedia

    en.wikipedia.org/wiki/Thermal_contact_conductance

    Thermal contact resistance is significant and may dominate for good heat conductors such as metals but can be neglected for poor heat conductors such as insulators. [2] Thermal contact conductance is an important factor in a variety of applications, largely because many physical systems contain a mechanical combination of

  9. Normal contact stiffness - Wikipedia

    en.wikipedia.org/wiki/Normal_contact_stiffness

    Normal contact stiffness is a physical quantity related to the generalized force displacement behavior of rough surfaces in contact with a rigid body or a second similar rough surface. [ 1 ] [ 2 ] Specifically it is the amount of force per unit displacement required to compress an elastic object in the contact region.
