  2. Process-data diagram - Wikipedia

    en.wikipedia.org/wiki/Process-data_diagram

    The process data diagram. A process-data diagram (PDD), also known as process-deliverable diagram is a diagram that describes processes and data that act as output of these processes. On the left side the meta-process model can be viewed and on the right side the meta-data model can be viewed. [1]

    en.wikipedia.org/wiki/Piezoelectric_direct...

    Piezoelectric direct discharge (PDD) plasma is a type of cold non-equilibrium plasma, generated by a direct gas discharge of a high voltage piezoelectric transformer.It can be ignited in air or other gases in a wide range of pressures, including atmospheric.

  4. Percentage depth dose curve - Wikipedia

    en.wikipedia.org/wiki/Percentage_depth_dose_curve

    Percent depth dose (PDD), which reflects the overall percentage of dose deposited as compared to the depth of maximum dose, depends on the depth of interest, beam energy, field size, and SSD (source to surface distance) as follows. Of note, PDD generally refers to depths greater than the depth of maximum dose

  5. Pantograph (transport) - Wikipedia

    en.wikipedia.org/wiki/Pantograph_(transport)

    The electric transmission system for modern electric rail systems consists of an upper, weight-carrying wire (known as a catenary) from which is suspended a contact wire. The pantograph is spring-loaded and pushes a contact shoe up against the underside of the contact wire to draw the current needed to run the train.
