Porting Authorisation Code. Porting Authorization Code ( PAC) is a unique identifier (normally 9 characters long and in the format "ABC123456") used by some mobile network operators to facilitate mobile number portability (MNP). This allows users to retain their mobile telephone number when switching operators.
Overview. Mobile number portability is implemented in varying ways across the globe. The international and European standard implements "recipient-led" porting, in which a customer wishing to port a telephone number contacts the new network (recipient), which sends the number portability request (NPR) to the current network operator (donor).
The FCC since has mandated Wireless Local Number Portability starting November 24, 2003 (in metropolitan areas) and allowed operators to charge an additional monthly Long-Term Telephone Number Portability End-Use Charge as compensation.
A charging station, also known as a charge point, chargepoint, or electric vehicle supply equipment ( EVSE ), is a power supply device that supplies electrical power for recharging plug-in electric vehicles (including battery electric vehicles, electric trucks, electric buses, neighborhood electric vehicles and plug-in hybrid vehicles ).
This rose to 28,100 long tons (28,600 t) of the planned 60,250 long tons (61,220 t), or 46 percent of the planned total by midnight on 10 June. Emergency beach dumps were established by the engineer special brigades on 7 and 8 June, and the planned inland dumps were opened over the next few days.
Schnuerle porting. Schnuerle porting [1] [2] is a system to improve efficiency of a valveless two-stroke engine by giving better scavenging. The intake and exhaust ports cut in the cylinder wall are shaped to give a more efficient transfer of intake and exhaust gases.
The wave activity in the port/runner does not stop but continues to reverberate for some time. When the valve next opens, the remaining waves influence the next cycle. This graph shows the pressure taken from the valve end (blue line) and the runner entrance(red line) of an engine with a 7-inch (180 mm) port/runner and running at 4500 rpm.
CHAdeMO is a fast-charging system for battery electric vehicles, developed in 2010 by the CHAdeMO Association, formed by the Tokyo Electric Power Company and five major Japanese automakers. [1] The name is an abbreviation of "CHArge de MOve" (which the organization translates as "charge for moving") and is derived from the Japanese phrase " o ...
