  2. Fan-out (software) - Wikipedia

    en.wikipedia.org/wiki/Fan-out_(software)

    In message-oriented middleware solutions, fan-out is a messaging pattern used to model an information exchange that implies the delivery (or spreading) of a message to one or multiple destinations possibly in parallel, and not halting the process that executes the messaging to wait for any response to that message. [1] [2] [3]

    en.wikipedia.org/wiki/Fan-out

    A perfect logic gate would have infinite input impedance and zero output impedance, allowing a gate output to drive any number of gate inputs.However, since real-world fabrication technologies exhibit less than perfect characteristics, a limit will be reached where a gate output cannot drive any more current into subsequent gate inputs - attempting to do so causes the voltage to fall below the ...

    Edge expanders can do direct table routing and subtractive routing. (For a brief discussion of these routing mechanisms, see below). Without a fanout expander, you can use at most two edge expanders in a delivery subsystem (because you connect the subtractive routing port of those edge expanders together, and you can not connect any more ...

  5. DEX (protocol) - Wikipedia

    en.wikipedia.org/wiki/DEX_(protocol)

    DEX (data exchange) is a format for collecting audit and event data from vending machines. DEX was introduced in the late 1980s by bottlers who provided product to vending machines. It was intended to improve auditing of vending machines, simplify inventory management. DEX records cash in/out, product movement and other audit data.

  6. Direct exchange geothermal heat pump - Wikipedia

    en.wikipedia.org/wiki/Direct_exchange_geothermal...

    DX system being drilled in the 1980s. A direct exchange (DX) geothermal heat pump is a type of ground source heat pump in which refrigerant circulates through copper tubing placed in the ground unlike other ground source heat pumps where refrigerant is restricted to the heat pump itself with a secondary loop in the ground filled with a mixture of water and anti-freeze.

  7. Superexchange - Wikipedia

    en.wikipedia.org/wiki/Superexchange

    While direct exchange can be either ferromagnetic or antiferromagnetic, the superexchange interaction is usually antiferromagnetic, preferring opposite alignment of the connected magnetic moments. Similar to the direct exchange, superexchange calls for the combined effect of Pauli exclusion principle and Coulomb's repulsion of the electrons.

  8. Fiber cable termination - Wikipedia

    en.wikipedia.org/wiki/Fiber_cable_termination

    A fanout kit is a set of empty jackets designed to protect fragile tight-buffered strands of fiber from a cable. This allows the individual fibers to be terminated without splicing, and without needing a protective enclosure such as a splicebox. This is normally an option with fiber distribution cable, or sometimes loose-buffer or ribbon cable ...

  9. Copper in heat exchangers - Wikipedia

    en.wikipedia.org/wiki/Copper_in_heat_exchangers

    Geothermal heat pump technology, variously known as "ground source," "earth-coupled," or "direct exchange," relies on circulating a refrigerant through buried copper tubing for heat exchange. These units, which are considerably more efficient than their air-source counterparts, rely on the constancy of ground temperatures below the frost zone ...
