  2. Master control - Wikipedia

    en.wikipedia.org/wiki/Master_control

    Master control is the technical hub of a broadcast operation common among most over-the-air television stations and television networks. [1] It is distinct from a production control room (PCR) in television studios where the activities such as switching from camera to camera are coordinated.

  3. Bang–bang control - Wikipedia

    en.wikipedia.org/wiki/Bang–bang_control

    Symbol for a bang–bang control. In control theory, a bang–bang controller (hysteresis, 2 step or on–off controller), is a feedback controller that switches abruptly between two states. These controllers may be realized in terms of any element that provides hysteresis. They are often used to control a plant that accepts a binary input, for ...

    When fuel flowing into the pump falls to very low pressure, gas bubbles form in the fuel. Bubble collapse on the high pressure side can cause damage to the pump's outlet ports. This video shows cavitation in a gear pump similar to that used in the Boeing 777. Mock-up of G-YMMM's fuel delivery system

  5. Pressure drop - Wikipedia

    en.wikipedia.org/wiki/Pressure_drop

    Pressure drop (often abbreviated as "dP" or "ΔP") [1] is defined as the difference in total pressure between two points of a fluid carrying network. A pressure drop occurs when frictional forces, caused by the resistance to flow, act on a fluid as it flows through a conduit (such as a channel, pipe, or tube).

  6. Optimal control - Wikipedia

    en.wikipedia.org/wiki/Optimal_control

    Optimal control problem benchmark (Luus) with an integral objective, inequality, and differential constraint. Optimal control theory is a branch of control theory that deals with finding a control for a dynamical system over a period of time such that an objective function is optimized. [1]

  8. Cathode-ray tube - Wikipedia

    en.wikipedia.org/wiki/Cathode-ray_tube

    The electron guns in color CRTs are driven by a video amplifier which takes a signal per color channel and amplifies it to 40–170 V per channel, to be fed into the electron gun's cathodes; [249] each electron gun has its own channel (one per color) and all channels may be driven by the same amplifier, which internally has three separate ...
