  2. Atmospheric-pressure plasma - Wikipedia

    en.wikipedia.org/wiki/Atmospheric-pressure_plasma

    Atmospheric-pressure plasma (or AP plasma or normal pressure plasma) is a plasma in which the pressure approximately matches that of the surrounding atmosphere – the so-called normal pressure. Fundamentals of atmospheric-pressure plasma generation

  3. Pressure–volume diagram - Wikipedia

    en.wikipedia.org/wiki/Pressure–volume_diagram

    A PV diagram plots the change in pressure P with respect to volume V for some process or processes. Typically in thermodynamics, the set of processes forms a cycle, so that upon completion of the cycle there has been no net change in state of the system; i.e. the device returns to the starting pressure and volume.

  4. AP Physics - Wikipedia

    en.wikipedia.org/wiki/AP_Physics

    AP Physics C: Mechanics and AP Physics 1 are both introductory college-level courses in mechanics, with the former recognized by more universities. [1] The AP Physics C: Mechanics exam includes a combination of conceptual questions, algebra-based questions, and calculus-based questions, while the AP Physics 1 exam includes only conceptual and algebra-based questions.

  5. SAP HANA - Wikipedia

    en.wikipedia.org/wiki/SAP_HANA

    SAP HANA Information Modeling (also known as SAP HANA Data Modeling) is a part of HANA application development. Modeling is the methodology to expose operational data to the end user. Reusable virtual objects (named calculation views) are used in the modelling process.

  6. Object Process Methodology - Wikipedia

    en.wikipedia.org/wiki/Object_Process_Methodology

    Object process methodology (OPM) is a conceptual modeling language and methodology for capturing knowledge and designing systems, specified as ISO/PAS 19450. [1] Based on a minimal universal ontology of stateful objects and processes that transform them, OPM can be used to formally specify the function, structure, and behavior of artificial and natural systems in a large variety of domains.

  7. Physical simulation - Wikipedia

    en.wikipedia.org/wiki/Physical_simulation

    The first model which may be used in physics engines governs the motion of infinitesimal objects with finite mass called “particles.” This equation, called Newton’s Second law (see Newton's laws) or the definition of force, is the fundamental behavior governing all motion:

  8. Event-driven process chain - Wikipedia

    en.wikipedia.org/wiki/Event-driven_Process_Chain

    These elements are used in event-driven process chain diagrams: Event Events are passive elements in event-driven process chains. They describe under what circumstances a function or a process works or which state a function or a process results in. Examples of events are "requirement captured", "material in stock", etc.

  9. Mandelstam variables - Wikipedia

    en.wikipedia.org/wiki/Mandelstam_variables

    In this diagram, two particles come in with momenta p 1 and p 2, they interact in some fashion, and then two particles with different momentum (p 3 and p 4) leave.. In theoretical physics, the Mandelstam variables are numerical quantities that encode the energy, momentum, and angles of particles in a scattering process in a Lorentz-invariant fashion.
