  • Trilateration - GIS Wiki | The GIS Encyclopedia

    Trilateration is a method for determining the intersections of three sphere surfaces given the centers and radii of the three spheres. Trilateration is used by GPS devices to compute exact location based on signals received from a satellite and the time that signal takes to get from the satellite to the receiver.

  • Switchgear - Wikipedia

    In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply.

  • Greenhouse gas - Wikipedia

    A greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect. The primary greenhouse gases in Earths atmosphere are water vapor (H 2 O), carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), and ozone (O 3).Without greenhouse gases, the average temperature of Earths surface would be about
