  2. Diameter Credit-Control Application - Wikipedia

    en.wikipedia.org/wiki/Diameter_Credit-Control...

    The purpose of the diameter credit control application is to provide a framework for real-time charging, primarily meant for the communication between gateways/control-points and the back-end account/balance systems (typically an Online Charging System). The application specifies methods for: Quota management (Reserve, Reauthorize, Abandon)

  3. Tailored blank - Wikipedia

    en.wikipedia.org/wiki/Tailored_blank

    Tailored blanks are semi-finished parts, which are typically made from sheets with different alloys, thicknesses, coatings or material properties. After joining, these will be subjected to deep drawing or stamping .

  4. Supercapacitor - Wikipedia

    en.wikipedia.org/wiki/Supercapacitor

    The electrochemical charge storage mechanisms in solid media can be roughly (there is an overlap in some systems) classified into 3 types: Electrostatic double-layer capacitors (EDLCs) use carbon electrodes or derivatives with much higher electrostatic double-layer capacitance than electrochemical pseudocapacitance, achieving separation of charge in a Helmholtz double layer at the interface ...

    Later thermionic vacuum tubes, mostly miniature style, some with top cap connections for higher voltages. A vacuum tube, electron tube, [1] [2] [3] [thermionic] valve (British usage), or tube (North America) [4] is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.

  7. Deep drawing - Wikipedia

    en.wikipedia.org/wiki/Deep_drawing

    Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. [1] It is thus a shape transformation process with material retention. The process is considered "deep" drawing when the depth of the drawn part exceeds its diameter.

    2 (absorbed from air or water) to form glucose and release oxygen. [108] All living cells use such fuels and oxidize the hydrogen and carbon to capture the sun's energy and reform water and CO 2 in the process (cellular respiration). Water is also central to acid-base neutrality and enzyme function. An acid, a hydrogen ion (H +
