  2. ADDIE Model - Wikipedia

    en.wikipedia.org/wiki/ADDIE_Model

    ADDIE is an instructional systems design (ISD) framework that many instructional designers and training developers use to develop courses. [1] The name is an acronym for the five phases it defines for building training and performance support tools:

  3. Blowoff valve - Wikipedia

    en.wikipedia.org/wiki/Blowoff_valve

    A blowoff valve is designed to release pressure in the intake system when the throttle is closed. A "recirculating" type blowoff valve releases the pressurised air back into the non-pressurized section of the intake (i.e. upstream of the turbocharger), while an "atmospheric venting" type blowoff valve dumps the air directly into the atmosphere.

    Permanent start-up, flush and bypass lines; Pipelines and flowlines; Blinds and spectacle blinds; Insulation and heat tracing; Process control instrumentation and designation (names, numbers, unique tag identifiers), including: Valves and their types and identifications (e.g. isolation, shutoff, relief and safety valves, valve interlocks)

  5. Bypass - Wikipedia

    en.wikipedia.org/wiki/Bypass

    Bypass capacitor, used to bypass a power supply or other high impedance component; Bypass ratio in turbofan aircraft engines Bypass duct, whose size controls the bypass ratio; Bypass switch, access port for an in-line active security appliance; Bypass (telecommunications) Bypass valve A blowoff valve on a compressor

  6. Wastegate - Wikipedia

    en.wikipedia.org/wiki/Wastegate

    An internal wastegate is a built-in bypass valve and passage within the turbocharger housing which allows excess exhaust pressure to bypass the turbine into the downstream exhaust. Control of the internal wastegate valve by a pressure signal from the intake manifold is identical to that of an external wastegate.

  7. Crankcase ventilation system - Wikipedia

    en.wikipedia.org/wiki/Crankcase_ventilation_system

    The crankcase air outlet, where the PCV valve is located, is generally placed as far as possible from the crankcase breather. For example, the breather and outlet are frequently on opposite valve covers on a V engine, or on opposite ends of the valve cover on an inline engine. The PCV valve is often, but not always, placed at the valve cover ...

  8. Self-contained breathing apparatus - Wikipedia

    en.wikipedia.org/wiki/Self-contained_breathing...

    Demand: 2000 psi to the regulator from the main valve, plus a bypass valve in case of failure, with a two-stage regulator reducing pressure to 50-100 psi. Pressure-Demand : Similar to demand, but with a spring in the diaphragm, which holds the admission valve open, for continuous air flow to the facepiece.

  9. Carry-skip adder - Wikipedia

    en.wikipedia.org/wiki/Carry-skip_adder

    A carry-skip adder [nb 1] (also known as a carry-bypass adder) is an adder implementation that improves on the delay of a ripple-carry adder with little effort compared to other adders. The improvement of the worst-case delay is achieved by using several carry-skip adders to form a block-carry-skip adder.
