  2. Direct-drive mechanism - Wikipedia

    en.wikipedia.org/wiki/Direct-drive_mechanism

    Direct-drive systems are characterized by smooth torque transmission, and nearly-zero backlash. [9] [10] [11] The main [citation needed] benefits of a direct-drive system are increased efficiency (due to reduced power losses from the drivetrain components) and being a simpler design with fewer moving parts.

  3. Guidance, navigation, and control - Wikipedia

    en.wikipedia.org/wiki/Guidance,_navigation,_and...

    Guidance, navigation and control (abbreviated GNC, GN&C, or G&C) is a branch of engineering dealing with the design of systems to control the movement of vehicles, especially, automobiles, ships, aircraft, and spacecraft. In many cases these functions can be performed by trained humans.

  4. Bilirubin - Wikipedia

    en.wikipedia.org/wiki/Bilirubin

    Bilirubin (BR) (from the Latin for "red bile") is a red-orange compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates.This catabolism is a necessary process in the body's clearance of waste products that arise from the destruction of aged or abnormal red blood cells. [3]

  5. Flight control modes - Wikipedia

    en.wikipedia.org/wiki/Flight_control_modes

    A flight control mode or flight control law is a computer software algorithm that transforms the movement of the yoke or joystick, made by an aircraft pilot, into movements of the aircraft control surfaces. The control surface movements depend on which of several modes the flight computer is in.

  6. Direct-drive sim racing wheel - Wikipedia

    en.wikipedia.org/wiki/Direct-drive_sim_racing_wheel

    Issues, quality, and performance indicators of direct-drive wheels, and of sim racing wheels in general, include detail and fidelity of force feedback, smooth torque transmission, nearly-zero backlash, rotary encoder resolution, clipping, dynamic range, torque ripple, [2] cogging torque, [10] drivers and digital signal processing with control electronics, [2] [11] signal filtering, [8 ...

  7. Heme - Wikipedia

    en.wikipedia.org/wiki/Heme

    Excretion of bilirubin from liver to biliary canaliculi is an active, energy-dependent and rate-limiting process. The intestinal bacteria deconjugate bilirubin diglucuronide releasing free bilirubin, which can either be reabsorbed or reduced to urobilinogen by the bacterial enzyme bilirubin reductase.

  8. Proportional–integral–derivative controller - Wikipedia

    en.wikipedia.org/wiki/Proportional–integral...

    Tuning a control loop is the adjustment of its control parameters (proportional band/gain, integral gain/reset, derivative gain/rate) to the optimum values for the desired control response. Stability (no unbounded oscillation) is a basic requirement, but beyond that, different systems have different behavior, different applications have ...

  9. Direct digital control - Wikipedia

    en.wikipedia.org/wiki/Direct_digital_control

    Direct digital control is the automated control of a condition or process by a digital device (computer). [ 1 ] [ 2 ] Direct digital control takes a centralized network-oriented approach. All instrumentation is gathered by various analog and digital converters which use the network to transport these signals to the central controller.
