  2. Gebhart factor - Wikipedia

    en.wikipedia.org/wiki/Gebhart_factor

    Gebhart factor. The Gebhart factors are used in radiative heat transfer, it is a means to describe the ratio of radiation absorbed by any other surface versus the total emitted radiation from given surface. As such, it becomes the radiation exchange factor between a number of surfaces.

  3. Linear energy transfer - Wikipedia

    en.wikipedia.org/wiki/Linear_energy_transfer

    Linear energy transfer. Diffusion cloud chamber with tracks of ionizing radiation (alpha particles) that are made visible as strings of droplets. In dosimetry, linear energy transfer (LET) is the amount of energy that an ionizing particle transfers to the material traversed per unit distance. It describes the action of radiation into matter.

  4. Orthogonal frequency-division multiplexing - Wikipedia

    en.wikipedia.org/wiki/Orthogonal_frequency...

    Conceptually, OFDM is a specialized frequency-division multiplexing (FDM) method, with the additional constraint that all subcarrier signals within a communication channel are orthogonal to one another. In OFDM, the subcarrier frequencies are chosen so that the subcarriers are orthogonal to each other, meaning that crosstalk between the sub ...

  5. Charge transport mechanisms - Wikipedia

    en.wikipedia.org/wiki/Charge_transport_mechanisms

    Characterization of transport properties requires fabricating a device and measuring its current-voltage characteristics. Devices for transport studies are typically fabricated by thin film deposition or break junctions. The dominant transport mechanism in a measured device can be determined by differential conductance analysis.

    statvolt (CGS unit) statV. ≘ c ⋅ (1 μJ/A⋅m) = 299.792458V. volt (SI unit) V. The difference in electric potential across two points along a conducting wire carrying one ampere of constant current when the power dissipated between the points equals one watt. [ 32 ] = 1 V = 1 W/A = 1 kg⋅m2/ (A⋅s3) = 1 J/C.

  7. Multi-mode optical fiber - Wikipedia

    en.wikipedia.org/wiki/Multi-mode_optical_fiber

    Multi-mode optical fiber. A stripped multi-mode fiber. Multi-mode optical fiber is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Multi-mode links can be used for data rates up to 800 Gbit/s. Multi-mode fiber has a fairly large core diameter that enables multiple light modes ...

    The SET rate follows the inverse of the fourth power of the distance [2] = where ⁠ ⁠ is the donor emission lifetime; ⁠ ⁠ is the distance between donor-acceptor; ⁠ ⁠ is the distance at which SET efficiency decreases to 50% (i.e., equal probability of energy transfer and spontaneous emission).

  9. Ethernet physical layer - Wikipedia

    en.wikipedia.org/wiki/Ethernet_physical_layer

    The physical-layer specifications of the Ethernet family of computer network standards are published by the Institute of Electrical and Electronics Engineers (IEEE), which defines the electrical or optical properties and the transfer speed of the physical connection between a device and the network or between network devices.
