  2. 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.

  3. Atmospheric radiative transfer codes - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_radiative...

    The radiative transfer equation is a monochromatic equation to calculate radiance in a single layer of the Earth's atmosphere. To calculate the radiance for a spectral region with a finite width (e.g., to estimate the Earth's energy budget or simulate an instrument response), one has to integrate this over a band of frequencies (or wavelengths).

  4. Cellular network - Wikipedia

    en.wikipedia.org/wiki/Cellular_network

    The first commercial cellular network, the 1G generation, was launched in Japan by Nippon Telegraph and Telephone (NTT) in 1979, initially in the metropolitan area of Tokyo. Within five years, the NTT network had been expanded to cover the whole population of Japan and became the first nationwide 1G network. It was an analog wireless network.

  5. IEEE 802.3 - Wikipedia

    en.wikipedia.org/wiki/IEEE_802.3

    IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer 's media access control (MAC) of wired Ethernet. The standards are produced by the working group of Institute of Electrical and Electronics Engineers (IEEE). This is generally a local area network (LAN) technology with some wide area ...

  6. 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.

  7. Gigabit Ethernet - Wikipedia

    en.wikipedia.org/wiki/Gigabit_Ethernet

    For the camera protocol, see GigE vision. Intel PRO/1000 GT PCI network interface controller. In computer networking, Gigabit Ethernet (GbE or 1 GigE) is the term applied to transmitting Ethernet frames at a rate of a gigabit per second. The most popular variant, 1000BASE-T, is defined by the IEEE 802.3ab standard.

  8. General circulation model - Wikipedia

    en.wikipedia.org/wiki/General_circulation_model

    Atmospheric models calculate winds, heat transfer, radiation, relative humidity, and surface hydrology within each grid and evaluate interactions with neighboring points. [1] A general circulation model (GCM) is a type of climate model. It employs a mathematical model of the general circulation of a planetary atmosphere or ocean.

  9. Radiative transfer - Wikipedia

    en.wikipedia.org/wiki/Radiative_transfer

    Radiative transfer. Radiative transfer (also called radiation transport) is the physical phenomenon of energy transfer in the form of electromagnetic radiation. The propagation of radiation through a medium is affected by absorption, emission, and scattering processes. The equation of radiative transfer describes these interactions mathematically.
