  2. Component parts of internal combustion engines - Wikipedia

    en.wikipedia.org/wiki/Component_parts_of...

    An illustration of several key components in a typical four-stroke engine. For a four-stroke engine, key parts of the engine include the crankshaft (purple), connecting rod (orange), one or more camshafts (red and blue), and valves. For a two-stroke engine, there may simply be an exhaust outlet and fuel inlet instead of a valve system.

  3. Control chart - Wikipedia

    en.wikipedia.org/wiki/Control_chart

    Control charts are graphical plots used in production control to determine whether quality and manufacturing processes are being controlled under stable conditions. (ISO 7870-1) [1] The hourly status is arranged on the graph, and the occurrence of abnormalities is judged based on the presence of data that differs from the conventional trend or deviates from the control limit line.

  4. Enthalpy–entropy chart - Wikipedia

    en.wikipedia.org/wiki/Enthalpy–entropy_chart

    An enthalpy–entropy chart, also known as the H–S chart or Mollier diagram, plots the total heat against entropy, [1] describing the enthalpy of a thermodynamic system. [2] A typical chart covers a pressure range of 0.01–1000 bar, and temperatures up to 800 degrees Celsius. [3] It shows enthalpy in terms of internal energy , pressure and ...

Bhabha scattering. electron-positron scattering. Penguin diagram. a quark changes flavor via a W or Z loop. Tadpole diagram. One loop diagram with one external leg.

  6. Bessemer process - Wikipedia

    en.wikipedia.org/wiki/Bessemer_process

    Bessemer process. The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature ...

  7. Process control block - Wikipedia

    en.wikipedia.org/wiki/Process_control_block

    A process control block ( PCB ), also sometimes called a process descriptor, is a data structure used by a computer operating system to store all the information about a process . When a process is created (initialized or installed), the operating system creates a corresponding process control block, which specifies and tracks the process state ...

  8. s-process - Wikipedia

    en.wikipedia.org/wiki/S-process

    s. -process. The slow neutron-capture process, or s-process, is a series of reactions in nuclear astrophysics that occur in stars, particularly asymptotic giant branch stars. The s -process is responsible for the creation ( nucleosynthesis) of approximately half the atomic nuclei heavier than iron . In the s -process, a seed nucleus undergoes ...

  9. Event-driven process chain - Wikipedia

    en.wikipedia.org/wiki/Event-driven_Process_Chain

    Example of a more complex EPC diagram (in German). An event-driven process chain ( EPC) is a type of flow chart for business process modeling. EPC can be used to configure enterprise resource planning execution, and for business process improvement. It can be used to control an autonomous workflow instance in work sharing.
